Limited access: gender, occupational composition, and flexible work scheduling.
Glauber, Rebecca
2011-01-01
The current study draws on national data to explore differences in access to flexible work scheduling by the gender composition of women's and men's occupations. Results show that those who work in integrated occupations are more likely to have access to flexible scheduling. Women and men do not take jobs with lower pay in return for greater access to flexibility. Instead, jobs with higher pay offer greater flexibility. Integrated occupations tend to offer the greatest access to flexible scheduling because of their structural locations. Part-time work is negatively associated with men's access to flexible scheduling but positively associated with women's access. Women have greater flexibility when they work for large establishments, whereas men have greater flexibility when they work for small establishments.

Rethinking the Clockwork of Work: Why Schedule Control May Pay Off at Work and at Home.
Kelly, Erin L; Moen, Phyllis
2007-11-01
Many employees face work-life conflicts and time deficits that negatively affect their health, well-being, effectiveness on the job, and organizational commitment. Many organizations have adopted flexible work arrangements but not all of them increase schedule control, that is, employees' control over when, where, and how much they work. This article describes some limitations of flexible work policies, proposes a conceptual model of how schedule control impacts work-life conflicts, and describes specific ways to increase employees' schedule control, including best practices for implementing common flexible work policies and Best Buy's innovative approach to creating a culture of schedule control.

Emotional exhaustion among healthcare workers is a widely investigated, well-recognized problem, the incidence of which has recently been linked to work environment factors, particularly work/family conflict. However, another environmental feature that may be equally influential, but that is more amenable to nurse manager action, remains less recognized: shift schedule flexibility. This study's main purposes were to assess variations in work schedule flexibility between Swiss acute care hospital units, and to investigate associations between psychosocial work environment (e.g. work schedule flexibility) and self-reported emotional exhaustion among registered nurses. This is a secondary analysis of data collected for the multi-center observational cross-sectional Match RN study, which included a national sample of 23 hospitals and 1833 registered nurses across Switzerland. Overall, self-reported work schedule flexibility among registered nurses was limited: 32% of participants reported little or no influence in planning their own shifts. Work schedule flexibility (β -0.11; CI -0.16; -0.06) and perceived nurse manager ability (β -0.30; CI -0.49; -0.10) were negatively related to self-reported emotional exhaustion. Work-family conflict (β 0.39; CI 0.33; 0.45) was positively correlated to emotional exhaustion. The study results indicate that managerial efforts to improve working environments, including special efforts to improve work schedule flexibility, might play an important role in promoting nurses' emotional health.

Contagious flexibility? A study on whether schedule flexibility facilitates work-life enrichment.
Pedersen, Vivi Bach; Jeppesen, Hans Jeppe
2012-08-01
Schedule flexibility defines an important generating resource for work-life enrichment; however, our knowledge about how such spillovers take place is limited. This multiple case study examines how workers from different working time contexts with varying levels of schedule flexibility experience work-life interplay. Given the adopted explorative design, it is important to interpret the findings in a tentative light. Nonetheless, the study offers important insight into work-life enrichment that may guide future research in this field. The findings indicate that schedule flexibility may act as a boundary-spanning resource owing to the agency potential it offers workers. Thus, it seemed that flexible schedule opportunities enabled workers to engage more fully in personal life activities, which in turn had a positive influence on their work involvement through positive affect. Such positive role engagements appeared, however, to be greatly determined by workers' boundary management and by time conditions of work and family. In conclusion, the major findings and limitation of the study are discussed against existing research and theory. © 2012 The Authors.

Periodic components inherent in actual schedules of flexible working hours and their interference with social rhythms were measured using spectrum analysis. The resulting indicators of periodicity and interference were then related to the reported social impairments of workers. The results show that a suppression of the 24 and the 168 h (seven-day) components (absence of periodicity) in the work schedules predicts reported social impairment. However, even if there are relatively strong 24 and 168 h components left in the work schedules, their interference with the social rhythm (using the phase difference between working hours and the utility of time) further predicts impairment. The results thus indicate that the periodicity of working hours and the amount of (social) desynchronization induced by flexible work schedules can be used both for predicting the impairing effects of the specific work schedules on social well-being as well as for the design of socially acceptable flexible work hours.

In order to analyze whether impairments to health and well-being under flexible working hours can be predicted from specific characteristics of the work schedules, periodic components in flexible working hours and their interference with the circadian temperature rhythm were analyzed applying univariate and bivariate spectrum analyses to both time series. The resulting indicators of spectral power and phase shift of these components were then related to reported health impairments using regression analysis. The results show that a suppression of both the 24 and the 168 h components in the work schedules (i.e., a lack of periodicity) can be used to predict reported health impairments, and that if there are relatively strong 24 and 168 h components left in the work schedules, their phase difference with the temperature rhythm (as an indicator of the interference between working time and the circadian rhythm) further predicts impairment. The results indicate that the periodicity of working hours and the amount of (circadian) desynchronization induced by flexible work schedules can be used for predicting the impairing effects of flexible work schedules on health and well-being. The results can thus be used for evaluating and designing flexible shift rosters.

Workplace flexibility, work hours, and work-life conflict: finding an extra day or two.
Hill, E Jeffrey; Erickson, Jenet Jacob; Holmes, Erin K; Ferris, Maria
2010-06-01
This study explores the influence of workplace flexibility on work-life conflict for a global sample of workers from four groups of countries. Data are from the 2007 International Business Machines Global Work and Life Issues Survey administered in 75 countries (N = 24,436). We specifically examine flexibility in where (work-at-home) and when (perceived schedule flexibility) workers engage in work-related tasks. Multivariate results indicate that work-at-home and perceived schedule flexibility are generally related to less work-life conflict. Break point analyses of sub-groups reveal that employees with workplace flexibility are able to work longer hours (often equivalent to one or two 8-hr days more per week) before reporting work-life conflict. The benefit of work-at-home is increased when combined with schedule flexibility. These findings were generally consistent across all four groups of countries, supporting the case that workplace flexibility is beneficial both to individuals (in the form of reduced work-life conflict) and to businesses (in the form of capacity for longer work hours). However, work-at-home appears less beneficial in countries with collectivist cultures. (c) 2010 APA, all rights reserved.

This study uses a dyadic approach to examine how an employee's work-family conflict is affected when his or her partner makes use of family-friendly work arrangements. We focused on 2 types of family-friendly practices, that is, reduced work hours and schedule or workplace flexibility. Hypotheses were tested with multilevel structural equation modeling using information of 186 dual-earner couples. In line with our hypotheses, we found support for both a positive and a negative crossover effect, though the results showed differences between the 2 types of family-friendly work arrangements. First, a positive crossover effect was found for both reduced work hours and schedule or workplace flexibility; however, the specific mechanisms explaining this effect differed per type of arrangements. In particular, employees whose partner made use of reduced work hours were found to experience less home demands, which was in turn associated with lower family-to-work conflict, whereas employees whose partner made use of schedule or workplace flexibility experienced a similar positive crossover effect but through an increase in the social support they perceived. Second, a negative crossover effect was found only for reduced work hours and not for schedule or workplace flexibility. Specifically, employees whose partner made use of reduced work hours were found to work on average more hours a week, which was in turn related with more work-to-family conflict, whereas employees whose partner made use of schedule or workplace flexibility worked on average fewer hours a week and consequently experienced lower work-to-family conflict. Implications for literature and practice are discussed. (c) 2016 APA, all rights reserved).

Work and Health of Parents of Adult Children with Serious Mental Illness.
Song, Jieun; Mailick, Marsha R; Greenberg, Jan S
2014-02-01
This study examined the effects of work schedule flexibility and the spillover of work stress to family life on the health of parents of adult children with serious mental illness (SMI). We compared 100 parents of adult children with SMI to 500 parents with nondisabled adult children using data from the Wisconsin Longitudinal Study. The detrimental impact on health of a lack of work flexibility and of higher levels of negative work-to-family spillover were more pronounced among parents of adult children with SMI than parents with non-disabled adult children. The results have significant implications for developing interventions to help midlife families of persons with SMI cope with work-related stress and for policies that provide for greater work schedule flexibility.
Families with school-age children.
Christensen, Kathleen; Schneider, Barbara; Butler, Donnell
2011-01-01
Most working parents face a common dilemma--how to care for their children when they are not in school but the parents are at work. In this article Kathleen Christensen, Barbara Schneider, and Donnell Butler describe the predictable and unpredictable scheduling demands school-age children place on working couples and single working parents. The authors assess the potential capacity of schools to help meet the needs of working families through changes in school schedules and after-school programs and conclude that the flexibility parents need to balance family-work responsibilities probably cannot be found in the school setting. They argue that workplaces are better able than schools to offer the flexibility that working parents need to attend to basic needs of their children, as well as to engage in activities that enhance their children's academic performance and emotional and social well-being. Two types of flexible work practices seem especially well suited to parents who work: flextime arrangements that allow parents to coordinate their work schedules with their children's school schedules, and policies that allow workers to take short periods of time off--a few hours or a day or two-to attend a parent-teacher conference, for example, or care for a child who has suddenly fallen ill. Many companies that have instituted such policies have benefited through employees' greater job satisfaction and employee retention. Yet despite these measured benefits to employers, workplaces often fall short of being family friendly. Many employers do not offer such policies or offer them only to employees at certain levels or in certain types of jobs. Flexible work practices are almost nonexistent for low-income workers, who are least able to afford alternative child care and may need flexibility the most. Moreover the authors find that even employees in firms with flexible practices such as telecommuting may be reluctant to take advantage of them, because the workplace culture explicitly or implicitly stigmatizes or penalizes employees for choosing these work arrangements. The authors conclude by making a case for creating a workplace culture that supports flexibility. Such a culture, they argue, would enable working parents to better meet the responsibilities of their jobs as they care for and build strong relationships with their children.

Flexible work schedules, older workers, and retirement.
Siegenthaler, J K; Brenner, A M
2000-01-01
Older workers in the United States indicate that they would prefer flexible work arrangements rather than abrupt retirement, yet management has done very little to make this possible. A review of two bodies of literature from the late 1980s is presented: social science writings including sociological, gerontological, and economic literature, and business and management literature. There is a clash between the way jobs are traditionally scheduled and the needs of growing numbers of older workers. Workers continue to be subject to obstacles to phased retirement due to the structuring of health care and pension benefits, downsizing, organizational inflexibility, and "corporate culture." Thus, general views among social scientists regarding the desirability of flexible schedules toward retirement will not produce real changes unless management becomes committed to such changes and they are securely embedded in company policies.

This paper proposes the impact assessment of the jobs order in the optimal time of operations in a Flexible Job Shop Scheduling Problem. In this work a real assembly cell was studied: the AIP-PRIMECA cell at the Université de Valenciennes et du Hainaut-Cambrésis, in France, which is considered as a Flexible Job Shop problem. The problem consists in finding the machines operations schedule, taking into account the precedence constraints. The main objective is to minimize the batch makespan, i.e. the finish time of the last operation completed in the schedule. Shortly, the present study consists in evaluating if the jobs order affects the optimal time of the operations schedule. The genetic algorithm was used to solve the optimization problem. As a conclusion, it's assessed that the jobs order influence the optimal time.
Enhancements of evolutionary algorithm for the complex requirements of a nurse scheduling problem
NASA Astrophysics Data System (ADS)
Tein, Lim Huai; Ramli, Razamin
2014-12-01
Over the years, nurse scheduling is a noticeable problem that is affected by the global nurse turnover crisis. The more nurses are unsatisfied with their working environment the more severe the condition or implication they tend to leave. Therefore, the current undesirable work schedule is partly due to that working condition. Basically, there is a lack of complimentary requirement between the head nurse's liability and the nurses' need. In particular, subject to highly nurse preferences issue, the sophisticated challenge of doing nurse scheduling is failure to stimulate tolerance behavior between both parties during shifts assignment in real working scenarios. Inevitably, the flexibility in shifts assignment is hard to achieve for the sake of satisfying nurse diverse requests with upholding imperative nurse ward coverage. Hence, Evolutionary Algorithm (EA) is proposed to cater for this complexity in a nurse scheduling problem (NSP). The restriction of EA is discussed and thus, enhancement on the EA operators is suggested so that the EA would have the characteristic of a flexible search. This paper consists of three types of constraints which are the hard, semi-hard and soft constraints that can be handled by the EA with enhanced parent selection and specialized mutation operators. These operators and EA as a whole contribute to the efficiency of constraint handling, fitness computation as well as flexibility in the search, which correspond to the employment of exploration and exploitation principles.

A dynamic scheduling algorithm for singe-arm two-cluster tools with flexible processing times
NASA Astrophysics Data System (ADS)
Li, Xin; Fung, Richard Y. K.
2018-02-01
This article presents a dynamic algorithm for job scheduling in two-cluster tools producing multi-type wafers with flexible processing times. Flexible processing times mean that the actual times for processing wafers should be within given time intervals. The objective of the work is to minimize the completion time of the newly inserted wafer. To deal with this issue, a two-cluster tool is decomposed into three reduced single-cluster tools (RCTs) in a series based on a decomposition approach proposed in this article. For each single-cluster tool, a dynamic scheduling algorithm based on temporal constraints is developed to schedule the newly inserted wafer. Three experiments have been carried out to test the dynamic scheduling algorithm proposed, comparing with the results the 'earliest starting time' heuristic (EST) adopted in previous literature.

One way of ensuring the continuity of health care is the shift work, which is burdensome and it can lead to sleep disturbances. The aim of the study was to measure the typical Hungarian nursing shift systems in hospitals, to analyse the causes of irregular work schedules, and to compare the sleep quality of nurses in different work schedules. 236 head nurses filled out the national online survey, and 217 nurses in clinics of the University of Pécs filled the Hungarian version of Bergen Shift Work Sleep Questionnaire. The head nurses provided data of 8697 nurses's schedules. 51.89% of nurses work in flexible shift system. 1944 employees work in regular shift system, most of them in the following order: 12-hour day shift and 12-hour night shift, followed by a one- or two-day rest. Where there is no system of shifts, the most frequent causes are the needs of nurses and the nurse shortage. Nurses who are working in irregular shift system had worse sleep quality than nurses who are working in flexible and regular shift system (p = 0.044). It would be helpful if the least burdensome shift system could be established.

This quasi-experimental study investigated how an intervention aiming at increasing eldercare workers' influence on their working hours affected the flexibility, variability, regularity and predictability of the working hours. We used baseline (n = 296) and follow-up (n = 274) questionnaire data and interviews with intervention-group participants (n = 32). The work units in the intervention group designed their own intervention comprising either implementation of computerised self-scheduling (subgroup A), collection of information about the employees' work-time preferences by questionnaires (subgroup B), or discussion of working hours (subgroup C). Only computerised self-scheduling changed the working hours and the way they were planned. These changes implied more flexible but less regular working hours and an experience of less predictability and less continuity in the care of clients and in the co-operation with colleagues. In subgroup B and C, the participants ended up discussing the potential consequences of more work-time influence without actually implementing any changes. Employee work-time influence may buffer the adverse effects of shift work. However, our intervention study suggested that while increasing the individual flexibility, increasing work-time influence may also result in decreased regularity of the working hours and less continuity in the care of clients and co-operation with colleagues.

The flexible manufacturing system (FMS) constitute of several programmable production work centers, material handling systems (MHSs), assembly stations and automatic storage and retrieval systems. In FMS, the automatic guided vehicles (AGVs) play a vital role in material handling operations and enhance the performance of the FMS in its overall operations. To achieve low makespan and high throughput yield in the FMS operations, it is highly imperative to integrate the production work centers schedules with the AGVs schedules. The Production schedule for work centers is generated by application of the Giffler and Thompson algorithm under four kind of priority hybrid dispatching rules. Then the clonal selection algorithm (CSA) is applied for the simultaneous scheduling to reduce backtracking as well as distance travel of AGVs within the FMS facility. The proposed procedure is computationally tested on the benchmark FMS configuration from the literature and findings from the investigations clearly indicates that the CSA yields best results in comparison of other applied methods from the literature.

The relationship between work arrangements and work-family conflict.
Higgins, Christopher; Duxbury, Linda; Julien, Mark
2014-01-01
A review of the literature determined that our understanding of the efficacy of flexible work arrangements (FWA) in reducing work-family conflict remains inconclusive. To shed light on this issue by examining the relationship between work-to-family conflict, in which work interferes with family (WFC), family-to-work conflict, in which family interferes with work (FWC), and four work arrangements: the traditional 9-5 schedule, compressed work weeks (CWWs) flextime, and telework. Hypotheses were tested on a sample of 16,145 employees with dependent care responsibilities. MANCOVA analysis was used with work arrangement as the independent variable and work interferes with family (WFC) and family interferes with work (FWC) as dependent variables. Work demands, non-work demands, income, job type and gender were entered into the analysis as covariates. The more flexible work arrangements such as flextime and telework were associated with higher levels of WFC than were fixed 9-to 5 and CWW schedules. Employees who teleworked reported higher FWC than their counterparts working a traditional 9-to-5 schedule particularly when work demands were high. The removal of both temporal and physical boundaries separating work and family domains results in higher levels of work-family interference in both directions. The results from this study suggest that policy makers and practitioners who are interested in improving employee well-being can reduce work-family conflict, and by extension improve employee mental health, by focusing on the effective use of traditional and CWW schedules rather than by implementing flextime and telework arrangements.

Nursing turnover is a major issue for health care managers, notably during the global nursing workforce shortage. Despite the often hierarchical structure of the data used in nursing studies, few studies have investigated the impact of the work environment on intention to leave using multilevel techniques. Also, differences between intentions to leave the current workplace or to leave the profession entirely have rarely been studied. The aim of the current study was to investigate how aspects of the nurse practice environment and satisfaction with work schedule flexibility measured at different organisational levels influenced the intention to leave the profession or the workplace due to dissatisfaction. Multilevel models were fitted using survey data from the RN4CAST project, which has a multi-country, multilevel, cross-sectional design. The data analysed here are based on a sample of 23,076 registered nurses from 2020 units in 384 hospitals in 10 European countries (overall response rate: 59.4%). Four levels were available for analyses: country, hospital, unit, and individual registered nurse. Practice environment and satisfaction with schedule flexibility were aggregated and studied at the unit level. Gender, experience as registered nurse, full vs. part-time work, as well as individual deviance from unit mean in practice environment and satisfaction with work schedule flexibility, were included at the individual level. Both intention to leave the profession and the hospital due to dissatisfaction were studied. Regarding intention to leave current workplace, there is variability at both country (6.9%) and unit (6.9%) level. However, for intention to leave the profession we found less variability at the country (4.6%) and unit level (3.9%). Intention to leave the workplace was strongly related to unit level variables. Additionally, individual characteristics and deviance from unit mean regarding practice environment and satisfaction with schedule flexibility were related to both outcomes. Major limitations of the study are its cross-sectional design and the fact that only turnover intention due to dissatisfaction was studied. We conclude that measures aiming to improve the practice environment and schedule flexibility would be a promising approach towards increased retention of registered nurses in both their current workplaces and the nursing profession as a whole and thus a way to counteract the nursing shortage across European countries.

Scheduling the future NASA Space Network: Experiences with a flexible scheduling prototype
NASA Technical Reports Server (NTRS)
Happell, Nadine; Moe, Karen L.; Minnix, Jay
1993-01-01
NASA's Space Network (SN) provides telecommunications and tracking services to low earth orbiting spacecraft. One proposal for improving resource allocation and automating conflict resolution for the SN is the concept of flexible scheduling. In this concept, each Payload Operations Control Center (POCC) will possess a Space Network User POCC Interface (SNUPI) to support the development and management of flexible requests. Flexible requests express the flexibility, constraints, and repetitious nature of the user's communications requirements. Flexible scheduling is expected to improve SN resource utilization and user satisfaction, as well as reduce the effort to produce and maintain a schedule. A prototype testbed has been developed to better understand flexible scheduling as it applies to the SN. This testbed consists of a SNUPI workstation, an SN scheduler, and a flexible request language that conveys information between the two systems. All three are being evaluated by operations personnel. Benchmark testing is being conducted on the scheduler to quantify the productivity improvements achieved with flexible requests.

Experts working for railway schedule planners still have to devote considerable time and effort for creating rolling stock allocation plans. In this paper, we propose a semiautomatic planning method for creating these plans. Our scheduler is able to interactively deal with flexible constraint-expression inputs and to output easy-to-understand failure messages. Owing to these useful features, the scheduler can provide results that are comparable to those obtained by experts and are obtained faster than before.

Telecommuting's differential impact on work-family conflict: is there no place like home?
Golden, Timothy D; Veiga, John F; Simsek, Zeki
2006-11-01
The literature on the impact of telecommuting on work-family conflict has been equivocal, asserting that telecommuting enhances work-life balance and reduces conflict, or countering that it increases conflict as more time and emotional energy are allocated to family. Surveying 454 professional-level employees who split their work time between an office and home, the authors examined how extensively working in this mode impacts work-to-family conflict and family-to-work conflict, as well as the contextual impact of job autonomy, scheduling flexibility, and household size. As hypothesized, the findings suggest that telecommuting has a differential impact on work-family conflict, such that the more extensively individuals work in this mode, the lower their work-to-family conflict, but the higher their family-to-work conflict. Additionally, job autonomy and scheduling flexibility were found to positively moderate telecommuting's impact on work-to-family conflict, but household size was found to negatively moderate telecommuting's impact on family-to-work conflict, suggesting that contextual factors may be domain specific.

Objective To document the role job control and schedule control play in shaping women’s physical activity, and how it delineates educational and racial variability in associations of job and social control with physical activity. Methods Prospective data were obtained from a community-based sample of working women (N = 302). Validated instruments measured job control and schedule control. Steps per day were assessed using New Lifestyles 800 activity monitors. Results Greater job control predicted more steps per day, whereas greater schedule control predicted fewer steps. Small indirect associations between ethnicity and physical activity were observed among women with a trade school degree or less but not for women with a college degree. Conclusions Low job control created barriers to physical activity among working women with a trade school degree or less. Greater schedule control predicted less physical activity, suggesting women do not use time “created” by schedule flexibility for personal health enhancement. PMID:24034681

Factors That Influence the Recruitment and Retention of Nurses in Public Health Agencies.
Yeager, Valerie A; Wisniewski, Janna M
Given challenges to recruiting nurses to public health and the growth in national policies focused on population health, it is crucial that public health agencies develop strategies to sustain this important group of employees. The objective of this study was to examine factors that influence nurses' decisions to work in public health agencies. This cross-sectional study examined perspectives of nurses who worked in state and local public health departments and responded to the 2010 Council on Linkages Between Academia and Public Health Practice's survey of public health workers. We calculated the mean rating of each recruitment and retention factor for nurses and non-nurses separately and compared differences by using t tests. We then used multivariate regression analysis to examine differences in ratings by role (ie, nurse or non-nurse). After controlling for personal and organizational characteristics, the influence of 5 recruitment factors was significantly stronger among nurses than among non-nurses: flexibility of work schedule ( P < .001), autonomy/employee empowerment ( P < .001), ability to innovate ( P = .002), specific duties and responsibilities ( P = .005), and identifying with the mission of the organization ( P = .02). The influence of 5 retention factors was stronger among nurses than among non-nurses : autonomy/employee empowerment ( P < .001), flexibility of work schedule ( P < .001), specific duties and responsibilities ( P < .001), opportunities for training/continuing education ( P = .03), and ability to innovate ( P = .008). Some factors that influence nurses to begin and remain working in local governmental public health agencies, such as flexible schedules and employee autonomy, are factors that governmental public health agencies can design into positions and highlight when recruiting from health care organizations, private industry, and academia.

Job sharing in clinical nutrition management: a plan for successful implementation.
Visocan, B J; Herold, L S; Mulcahy, M J; Schlosser, M F
1993-10-01
While women continue to enter the American work force in record numbers; many experience difficulty in juggling career and family obligations. Flexible scheduling is one option used to ease work and family pressures. Women's changing work roles have potentially noteworthy implications for clinical nutrition management, a traditionally female-dominated profession where the recruitment and retention of valued, experienced registered dietitians can prove to be a human resources challenge. Job sharing, one type of flexible scheduling, is applicable to the nutrition management arena. This article describes and offers a plan for overcoming obstacles to job sharing, including determining feasibility, gaining support of top management, establishing program design, announcing the job share program, and using implementation, monitoring, and fine-tuning strategies. Benefits that can be derived from a successful job share are reduced absenteeism, decreased turnover, enhanced recruitment, improved morale, increased productivity, improved job coverage, and enhanced skills and knowledge base. A case study illustrates one method for achieving job sharing success in clinical nutrition management.
Flexible working conditions and their effects on employee health and wellbeing.
Joyce, Kerry; Pabayo, Roman; Critchley, Julia A; Bambra, Clare

Flexible working conditions are increasingly popular in developed countries but the effects on employee health and wellbeing are largely unknown. To evaluate the effects (benefits and harms) of flexible working interventions on the physical, mental and general health and wellbeing of employees and their families. Our searches (July 2009) covered 12 databases including the Cochrane Public Health Group Specialised Register, CENTRAL; MEDLINE; EMBASE; CINAHL; PsycINFO; Social Science Citation Index; ASSIA; IBSS; Sociological Abstracts; and ABI/Inform. We also searched relevant websites, handsearched key journals, searched bibliographies and contacted study authors and key experts. Randomised controlled trials (RCT), interrupted time series and controlled before and after studies (CBA), which examined the effects of flexible working interventions on employee health and wellbeing. We excluded studies assessing outcomes for less than six months and extracted outcomes relating to physical, mental and general health/ill health measured using a validated instrument. We also extracted secondary outcomes (including sickness absence, health service usage, behavioural changes, accidents, work-life balance, quality of life, health and wellbeing of children, family members and co-workers) if reported alongside at least one primary outcome. Two experienced review authors conducted data extraction and quality appraisal. We undertook a narrative synthesis as there was substantial heterogeneity between studies. Ten studies fulfilled the inclusion criteria. Six CBA studies reported on interventions relating to temporal flexibility: self-scheduling of shift work (n = 4), flexitime (n = 1) and overtime (n = 1). The remaining four CBA studies evaluated a form of contractual flexibility: partial/gradual retirement (n = 2), involuntary part-time work (n = 1) and fixed-term contract (n = 1). The studies retrieved had a number of methodological limitations including short follow-up periods, risk of selection bias and reliance on largely self-reported outcome data. Four CBA studies on self-scheduling of shifts and one CBA study on gradual/partial retirement reported statistically significant improvements in either primary outcomes (including systolic blood pressure and heart rate; tiredness; mental health, sleep duration, sleep quality and alertness; self-rated health status) or secondary health outcomes (co-workers social support and sense of community) and no ill health effects were reported. Flexitime was shown not to have significant effects on self-reported physiological and psychological health outcomes. Similarly, when comparing individuals working overtime with those who did not the odds of ill health effects were not significantly higher in the intervention group at follow up. The effects of contractual flexibility on self-reported health (with the exception of gradual/partial retirement, which when controlled by employees improved health outcomes) were either equivocal or negative. No studies differentiated results by socio-economic status, although one study did compare findings by gender but found no differential effect on self-reported health outcomes. The findings of this review tentatively suggest that flexible working interventions that increase worker control and choice (such as self-scheduling or gradual/partial retirement) are likely to have a positive effect on health outcomes. In contrast, interventions that were motivated or dictated by organisational interests, such as fixed-term contract and involuntary part-time employment, found equivocal or negative health effects. Given the partial and methodologically limited evidence base these findings should be interpreted with caution. Moreover, there is a clear need for well-designed intervention studies to delineate the impact of flexible working conditions on health, wellbeing and health inequalities.

Nurses aged over 50 years and their experiences of shift work.
Clendon, Jill; Walker, Leonie
2013-10-01
The Late Career Nurse project examined views and characteristics of nurses working in New Zealand who were born before 1960. This paper focuses on the experiences of such nurses who undertake shift work. The mean age of registered nurses in New Zealand has been rising steadily, and 40% are now aged 50 years or over. While there is substantial literature on the phenomenon and consequences of the ageing nursing workforce, little is known of the particular experiences of nurses aged over 50 years who work shifts. An anonymous online survey was emailed to eligible nurse New Zealand Nurses Organisation members aged over 50 years in February 2012. Quantitative and qualitative analyses of the 3273 responses received were undertaken. Over 45% of respondents worked shifts or flexible hours. While shift work suited many, others noted deleterious effects on family and social relationships, physical and mental health (notably sleep patterns and fatigue), and decreasing tolerance for shift work as they age. Poor scheduling practices were particularly detrimental. Worldwide, workforce ageing means strategies are required to retain older nurses in the workforce. Improved scheduling practices including increasing access to flexible and part time work hours, and development of resources on coping with shift work are recommended. © 2013 John Wiley & Sons Ltd.
Breastfeeding policies and breastfeeding support programs in the mother's workplace.
Bettinelli, Maria Enrica
2012-10-01
Women should never be forced to make a choice between mother-work and other work. Many women mistakenly think they cannot breastfeed if they plan to return to work, and thus they may not talk with their employers about their intention to breastfeed or how breastfeeding might be supported at their workplace. All breastfeeding policies and strategies underline the importance of providing support for lactating mothers and highlight the need to promote specific interventions in the workplace. Possible strategies for working mothers include having the mother keep the baby with her while she works, allowing the mother to go to the baby to breastfeed during the workday, telecommuting, offering flexible work schedules, maintaining part-time work schedules, and using on-site or nearby child care centres.

How Home Health Nurses Plan Their Work Schedules: A Qualitative Descriptive Study.
Irani, Elliane; Hirschman, Karen B; Cacchione, Pamela Z; Bowles, Kathryn H
2018-06-12
To describe how home health nurses plan their daily work schedules and what challenges they face during the planning process. Home health nurses are viewed as independent providers and value the nature of their work because of the flexibility and autonomy they hold in developing their work schedules. However, there is limited empirical evidence about how home health nurses plan their work schedules, including the factors they consider during the process and the challenges they face within the dynamic home health setting. Qualitative descriptive design. Semi-structured interviews were conducted with 20 registered nurses who had greater than 2 years of experience in home health and were employed by one of the three participating home health agencies in the mid-Atlantic region of the United States. Data were analyzed using conventional content analysis. Four themes emerged about planning work schedules and daily itineraries: identifying patient needs to prioritize visits accordingly, partnering with patients to accommodate their preferences, coordinating visit timing with other providers to avoid overwhelming patients, and working within agency standards to meet productivity requirements. Scheduling challenges included readjusting the schedule based on patient needs and staffing availability, anticipating longer visits, and maintaining continuity of care with patients. Home health nurses make autonomous decisions regarding their work schedules while considering specific patient and agency factors, and overcome challenges related to the unpredictable nature of providing care in a home health setting. Future research is needed to further explore nurse productivity in home health and improve home health work environments. Home health nurses plan their work schedules to provide high quality care that is patient-centered and timely. The findings also highlight organizational priorities to facilitate continuity of care and support nurses while alleviating the burnout associated with high productivity requirements.

Poor balance between work and family can be a major stressor for women with young children and have a negative impact on emotional well-being. Family-friendly workplace attributes may reduce stress and depressive symptoms among this population. However, few studies have analyzed the role of specific workplace attributes on mental health outcomes among women with young children because available data are limited. This study examines the impact of workplace attributes on changes in depressive symptoms among working women with young children between 6 and 24 months of age. This study uses data from the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care and Youth Development (SECCYD) collected between 1991 and 1993 to examine the effects of work intensity, work schedule (night/day/variable), schedule flexibility, working from home, and work stress on changes in depressive symptoms among a national US sample of 570 women who returned to work within 6 months after childbirth. Depressive symptoms were assessed using the CES-D score. Treatment effects were estimated using fixed effects regression models. Working from home and work stress predicted within-individual changes in depressive symptoms between 6 and 24 months postchildbirth. Women who worked from home reported a statistically significant decrease in depression scores over time (β = -1.36, SE = 0.51, p = 0.002). Women who reported a one-unit increase in job concerns experienced, on average, a 2-point increase in depression scores over time (β = 1.73, SE = 0.37, p < 0.01). Work intensity, work schedule, and schedule flexibility were not associated with changes in depressive symptoms. This study is one of the few to use longitudinal data and causal-inference techniques to examine whether specific workplace attributes influence depressive symptoms among women with young children. Reducing stress in the workplace and allowing women to work from home may improve mental health among women who transition back to work soon after childbirth.

Flexibility as a management principle in dementia care: the Adards example.
Cohen-Mansfield, Jiska; Bester, Allan
2006-08-01
Flexibility is an essential ingredient of person-centered care. We illustrate the potential impact of flexibility by portraying a nursing home that uses flexibility in its approach to residents and staff members. The paper describes the management strategies, principles, and environmental features used by the Adards nursing home in Australia. Adards' flexibility in daily work and task scheduling promotes both resident and staff autonomy, which in turn allows for higher staffing levels, lower staff turnover, and more typical life experiences for residents than is found in many long-term-care facilities in the United States. The article provides an example and a basis for future discussion on this topic, with the hope that it will prompt other institutions to expand the level of flexibility in their policies and procedures.
Workplace Policies and Mental Health among Working-Class, New Parents
Perry-Jenkins, Maureen; Smith, JuliAnna Z.; Wadsworth, Lauren Page; Halpern, Hillary Paul
2017-01-01
Little research has explored linkages between workplace policies and mental health in working-class, employed parents, creating a gap in our knowledge of work-family issues across social class levels. The current U.S. study addresses this gap by employing hierarchical linear modeling techniques to examine how workplace policies and parental leave benefits predicted parents' depressive symptoms and anxiety in a sample of 125, low-income, dual-earner couples interviewed across the transition to parenthood. Descriptive analyses revealed that, on average, parents had few workplace policies, such as schedule flexibility or child care supports, available to them. Results revealed, however, that, when available, schedule flexibility was related to fewer depressive symptoms and less anxiety for new mothers. Greater child care supports predicted fewer depressive symptoms for fathers. In terms of crossover effects, longer maternal leave predicted declines in fathers' anxiety across the first year. Results are discussed with attention to how certain workplace policies may serve to alleviate new parents' lack of time and resources (minimize scarcity of resources) and, in turn, predict better mental health during the sensitive period of new parenthood.

Mixed Criticality Scheduling for Industrial Wireless Sensor Networks
Jin, Xi; Xia, Changqing; Xu, Huiting; Wang, Jintao; Zeng, Peng
2016-01-01
Wireless sensor networks (WSNs) have been widely used in industrial systems. Their real-time performance and reliability are fundamental to industrial production. Many works have studied the two aspects, but only focus on single criticality WSNs. Mixed criticality requirements exist in many advanced applications in which different data flows have different levels of importance (or criticality). In this paper, first, we propose a scheduling algorithm, which guarantees the real-time performance and reliability requirements of data flows with different levels of criticality. The algorithm supports centralized optimization and adaptive adjustment. It is able to improve both the scheduling performance and flexibility. Then, we provide the schedulability test through rigorous theoretical analysis. We conduct extensive simulations, and the results demonstrate that the proposed scheduling algorithm and analysis significantly outperform existing ones. PMID:27589741
Dynamic Appliances Scheduling in Collaborative MicroGrids System
Bilil, Hasnae; Aniba, Ghassane; Gharavi, Hamid
2017-01-01
In this paper a new approach which is based on a collaborative system of MicroGrids (MG’s), is proposed to enable household appliance scheduling. To achieve this, appliances are categorized into flexible and non-flexible Deferrable Loads (DL’s), according to their electrical components. We propose a dynamic scheduling algorithm where users can systematically manage the operation of their electric appliances. The main challenge is to develop a flattening function calculus (reshaping) for both flexible and non-flexible DL’s. In addition, implementation of the proposed algorithm would require dynamically analyzing two successive multi-objective optimization (MOO) problems. The first targets the activation schedule of non-flexible DL’s and the second deals with the power profiles of flexible DL’s. The MOO problems are resolved by using a fast and elitist multi-objective genetic algorithm (NSGA-II). Finally, in order to show the efficiency of the proposed approach, a case study of a collaborative system that consists of 40 MG’s registered in the load curve for the flattening program has been developed. The results verify that the load curve can indeed become very flat by applying the proposed scheduling approach. PMID:28824226
Benefits and work-schedule options in hospital pharmacy practice.
Gaither, C A; Mason, N A; Diokno, D A; Hoffman, E J
1994-03-15
Hospital pharmacy directors were surveyed to determine whether their departments offered specific family-related benefits and work-schedule options and how their attitudes about these options compared with those of female hospital pharmacists. Questionnaires were mailed to 300 randomly selected hospital pharmacy directors to collect the following information: vacancy rates and male:female ratios in hospital pharmacy positions, which of 13 selected benefits and work-schedule options were offered, barriers that prevented the other options from being offered, and attitudes about the listed options. The options included in the survey were selected because they represent ways of balancing home and work (e.g., maternity leave, job sharing, day care). The pharmacy directors' responses were compared with those from a similar survey of female hospital pharmacists. The usable response rate was 50.3%. Position vacancy rates ranged from 5.5% for directors to 35.8% for clinical supervisors. All full-time positions had an even distribution of men and women except for director and assistant or associate director positions. Of 13 options, only maternity leave, part-time schedules, and flexible schedules were offered by more than half of the hospitals. These three were also the only listed options that the respondents considered important in recruiting and retaining pharmacists. Barriers to offering other options included the perception that current benefits and work-schedule options were adequate, lack of staff coverage, lack of funds, and the perception that some positions are not compatible with alternative schedules. Respondents' ratings of the importance of the listed benefits and work-schedule options were significantly lower than ratings given by female hospital pharmacists in a separate survey.(ABSTRACT TRUNCATED AT 250 WORDS)

This study presents a multi-timescale control strategy to deploy demand flexibilities of electric vehicles (EV) for providing system balancing and local congestion management by simultaneously ensuring economic benefits to participating actors. First, the EV charging problem from consumer, aggregator, and grid operator’s perspective is investigated. A hierarchical control architecture (HCA) comprising scheduling, coordinative, and adaptive layers is then designed to realize their coordinative goal. This is realized by integrating a multi-time scale control, which works from a day-ahead scheduling up to real-time adaptive control. The performance of the developed method is investigated with high EV penetration in a typical distributionmore » network. The simulation results demonstrates that HCA exploit EV flexibility to solve grid unbalancing and congestions with simultaneous maximization of economic benefits by ensuring EV participation to day-ahead, balancing, and regulation markets. For the given network configuration and pricing structure, HCA ensures the EV owners to get paid up to 5 times the cost they were paying without control.« less

Employees' work responses to episodes of illness: evidence from the American time use survey.
Gifford, Brian; Jinnett, Kimberly
2014-02-01
To better understand presenteeism and absenteeism on the basis of the choices employees make about working when they experience episodes of illness. We examine nationally representative data to describe employees' work responses to episodes of illness and how different leave policies contribute to their decisions. Illness episodes typically result in absence from work rather than working a normal or adjusted routine. Employees adjust their routine when ill primarily to save leave or because they have too much work. Paid sick leave and scheduling flexibility influence the likelihood of absence in different ways. Although flexibility to adjust work routines can reduce absences, it is not known to what extent productivity suffers when this occurs. Measures of both short- and long-term presenteeism are necessary to understand the full productivity costs of illness in the workforce.
Scheduling nursing personnel on a microcomputer.
Liao, C J; Kao, C Y
1997-01-01
Suggests that with the shortage of nursing personnel, hospital administrators have to pay more attention to the needs of nurses to retain and recruit them. Also asserts that improving nurses' schedules is one of the most economic ways for the hospital administration to create a better working environment for nurses. Develops an algorithm for scheduling nursing personnel. Contrary to the current hospital approach, which schedules nurses on a person-by-person basis, the proposed algorithm constructs schedules on a day-by-day basis. The algorithm has inherent flexibility in handling a variety of possible constraints and goals, similar to other non-cyclical approaches. But, unlike most other non-cyclical approaches, it can also generate a quality schedule in a short time on a microcomputer. The algorithm was coded in C language and run on a microcomputer. The developed software is currently implemented at a leading hospital in Taiwan. The response to the initial implementation is quite promising.

This article investigates a change in the structuring of work time, using a natural experiment to test whether participation in a corporate initiative (Results Only Work Environment; ROWE) predicts corresponding changes in health-related outcomes. Drawing on job strain and stress process models, we theorize greater schedule control and reduced work-family conflict as key mechanisms linking this initiative with health outcomes. Longitudinal survey data from 659 employees at a corporate headquarters shows that ROWE predicts changes in health-related behaviors, including almost an extra hour of sleep on work nights. Increasing employees' schedule control and reducing their work-family conflict are key mechanisms linking the ROWE innovation with changes in employees' health behaviors; they also predict changes in well-being measures, providing indirect links between ROWE and well-being. This study demonstrates that organizational changes in the structuring of time can promote employee wellness, particularly in terms of prevention behaviors.

The American Board of Surgery now permits general surgery residents to complete their clinical training over a 6-year period. Despite this new policy, the level of interest in flexible scheduling remains undefined. We sought to determine why residents and program directors (PDs) are interested in flexible tracks and to understand implementation barriers. National survey. All United States general surgery residency programs that participate in the Association of Program Directors in Surgery listserv. PDs and categorical general surgery residents in the United States. Attitudes about flexible tracks in surgery training. A flexible track was defined as a schedule that allows residents to pursue nonclinical time during residency with resulting delay in residency completion. Of the 748 residents and 81 PDs who responded, 505 residents and 45 PDs were supportive of flexible tracks (68% vs 56%, p = 0.03). Residents and PDs both were interested in flexible tracks to pursue research (86% vs 82%, p = 0.47) and child bearing (69% vs 58%, p = 0.13), but residents were more interested in pursuing international work (74% vs 53%, p = 0.004) and child rearing (63% vs 44%, p = 0.02). Although 71% of residents believe that flexible-track residents would not be respected as the equal of other residents, only 17% of PDs indicated they would not respect flexible-track residents (p < 0.001). Most residents and PDs support flexible tracks, although they differ in their motivation and perceived barriers. This finding lends support to the new policy of the American Board of Surgery.

Increasing operating room productivity by duration categories and a newsvendor model.
Lehtonen, Juha-Matti; Torkki, Paulus; Peltokorpi, Antti; Moilanen, Teemu
2013-01-01
Previous studies approach surgery scheduling mainly from the mathematical modeling perspective which is often hard to apply in a practical environment. The aim of this study is to develop a practical scheduling system that considers the advantages of both surgery categorization and newsvendor model to surgery scheduling. The research was carried out in a Finnish orthopaedic specialist centre that performs only joint replacement surgery. Four surgery categorization scenarios were defined and their productivity analyzed by simulation and newsvendor model. Detailed analyses of surgery durations and the use of more accurate case categories and their combinations in scheduling improved OR productivity 11.3 percent when compared to the base case. Planning to have one OR team to work longer led to remarkable decrease in scheduling inefficiency. In surgical services, productivity and cost-efficiency can be improved by utilizing historical data in case scheduling and by increasing flexibility in personnel management. The study increases the understanding of practical scheduling methods used to improve efficiency in surgical services.
Data location-aware job scheduling in the grid. Application to the GridWay metascheduler
NASA Astrophysics Data System (ADS)
Delgado Peris, Antonio; Hernandez, Jose; Huedo, Eduardo; Llorente, Ignacio M.
2010-04-01
Grid infrastructures constitute nowadays the core of the computing facilities of the biggest LHC experiments. These experiments produce and manage petabytes of data per year and run thousands of computing jobs every day to process that data. It is the duty of metaschedulers to allocate the tasks to the most appropriate resources at the proper time. Our work reviews the policies that have been proposed for the scheduling of grid jobs in the context of very data-intensive applications. We indicate some of the practical problems that such models will face and describe what we consider essential characteristics of an optimum scheduling system: aim to minimise not only job turnaround time but also data replication, flexibility to support different virtual organisation requirements and capability to coordinate the tasks of data placement and job allocation while keeping their execution decoupled. These ideas have guided the development of an enhanced prototype for GridWay, a general purpose metascheduler, part of the Globus Toolkit and member of the EGEE's RESPECT program. Current GridWay's scheduling algorithm is unaware of data location. Our prototype makes it possible for job requests to set data needs not only as absolute requirements but also as functions for resource ranking. As our tests show, this makes it more flexible than currently used resource brokers to implement different data-aware scheduling algorithms.

This paper studies a manpower scheduling problem with multiple maintenance operations and vehicle routing considerations. Service teams located at a common service centre are required to travel to different customer sites. All customers must be served within given time window, which are known in advance. The scheduling process must take into consideration complex constraints such as a meal break during the team's shift, multiple travelling trips, synchronisation of service teams and working shifts. The main objective of this study is to develop a heuristic that can generate high quality solution in short time for large problem instances. A Two-stage Scheduling Heuristic is developed for different variants of the problem. Empirical results show that the proposed solution performs effectively and efficiently. In addition, our proposed approximation algorithm is very flexible and can be easily adapted to different scheduling environments and operational requirements.
The role of workplace characteristics in breastfeeding practices.
Jacknowitz, Alison
2008-01-01
The present analyses were undertaken to understand the role of workplace characteristics in the breastfeeding practices of working women. The effects of the perception of the availability of employer-sponsored child care, the perception of the availability of a flexible schedule, hours worked at home, and worked a fixed schedule on breastfeeding outcomes were estimated using a sample of 1,506 births from the National Longitudinal Survey of Youth 1979 and the Children of the National Longitudinal Survey of Youth 1979. The availability of employer-sponsored child care increased the likelihood of breastfeeding six months after birth by 47 percent. In addition, working an additional eight hours at home per week, at the mean, increased the probability of breastfeeding initiation by 8 percent and breastfeeding six months after birth by 16.8 percent. Workplace characteristics show promise as an effective way to increase breastfeeding rates among working women.
Nonuniform sampling by quantiles.
Craft, D Levi; Sonstrom, Reilly E; Rovnyak, Virginia G; Rovnyak, David
2018-03-01
A flexible strategy for choosing samples nonuniformly from a Nyquist grid using the concept of statistical quantiles is presented for broad classes of NMR experimentation. Quantile-directed scheduling is intuitive and flexible for any weighting function, promotes reproducibility and seed independence, and is generalizable to multiple dimensions. In brief, weighting functions are divided into regions of equal probability, which define the samples to be acquired. Quantile scheduling therefore achieves close adherence to a probability distribution function, thereby minimizing gaps for any given degree of subsampling of the Nyquist grid. A characteristic of quantile scheduling is that one-dimensional, weighted NUS schedules are deterministic, however higher dimensional schedules are similar within a user-specified jittering parameter. To develop unweighted sampling, we investigated the minimum jitter needed to disrupt subharmonic tracts, and show that this criterion can be met in many cases by jittering within 25-50% of the subharmonic gap. For nD-NUS, three supplemental components to choosing samples by quantiles are proposed in this work: (i) forcing the corner samples to ensure sampling to specified maximum values in indirect evolution times, (ii) providing an option to triangular backfill sampling schedules to promote dense/uniform tracts at the beginning of signal evolution periods, and (iii) providing an option to force the edges of nD-NUS schedules to be identical to the 1D quantiles. Quantile-directed scheduling meets the diverse needs of current NUS experimentation, but can also be used for future NUS implementations such as off-grid NUS and more. A computer program implementing these principles (a.k.a. QSched) in 1D- and 2D-NUS is available under the general public license. Copyright © 2018 Elsevier Inc. All rights reserved.

[Burden and health effects of shift work].
Heitmann, Jörg
2010-10-01
In Germany aprox. 15% of all employees have irregular or flexible working hours. Disturbed sleep and/or hypersomnia are direct consequences of shift work and therefore described as shift work disorder. Beyond this, shift work can also be associated with specific pathological disorders. There are individual differences in tolerance to shift work. Optimization of both shift schedules and sleep to "non-physiological" times of the day are measures to counteract the negative effects of shift work. There is still not enough evidence to recommend drugs for routine use in shift workers. © Georg Thieme Verlag Stuttgart · New York.

As we move into the next era of geodetic VLBI, the scheduling process is one focus for improvement in terms of increased flexibility and the ability to react with changing conditions. A range of simulations were conducted to ascertain the impact of scheduling on geodetic results such as Earth Orientation Parameters (EOPs) and station coordinates. The potential capabilities of new automated scheduling modes were also simulated, using the so-called 'dynamic scheduling' technique. The primary aim was to improve efficiency for both cost and time without losing geodetic precision, particularly to maximise the uses of the Australian AuScope VLBI array. We show that short breaks in observation will not significantly degrade the results of a typical 24 h experiment, whereas simply shortening observing time degrades precision exponentially. We also confirm the new automated, dynamic scheduling mode is capable of producing the same standard of result as a traditional schedule, with close to real-time flexibility. Further, it is possible to use the dynamic scheduler to augment the 3 station Australian AuScope array and thereby attain EOPs of the current global precision with only intermittent contribution from 2 additional stations. We thus confirm automated, dynamic scheduling bears great potential for flexibility and automation in line with aims for future continuous VLBI operations.

The Joint Astronomy Centre operates two telescopes at the Mauna Kea Observatory: the James Clerk Maxwell Telescope, operating in the submillimetre, and the United Kingdom Infrared Telescope, operating in the near and thermal infrared. Both wavelength regimes benefit from the ability to schedule observations flexibly according to observing conditions, albeit via somewhat different "site quality" criteria. Both UKIRT and JCMT now operate completely flexible schedules. These operations are based on telescope hardware which can quickly switch between observing modes, and on a comprehensive suite of software (ORAC/OMP) which handles observing preparation by remote PIs, observation submission into the summit database, conditions-based programme selection at the summit, pipeline data reduction for all observing modes, and instant data quality feedback to the PI who may or may not be remote from the telescope. This paper describes the flexible scheduling model and presents science statistics for the first complete year of UKIRT and JCMT observing under the combined system.
Applications of colored petri net and genetic algorithms to cluster tool scheduling

In this paper, we propose a method, which uses Coloured Petri Net (CPN) and genetic algorithm (GA) to obtain an optimal deadlock-free schedule and to solve re-entrant problem for the flexible process of the cluster tool. The process of the cluster tool for producing a wafer usually can be classified into three types: 1) sequential process, 2) parallel process, and 3) sequential parallel process. But these processes are not economical enough to produce a variety of wafers in small volume. Therefore, this paper will propose the flexible process where the operations of fabricating wafers are randomly arranged to achieve the best utilization of the cluster tool. However, the flexible process may have deadlock and re-entrant problems which can be detected by CPN. On the other hand, GAs have been applied to find the optimal schedule for many types of manufacturing processes. Therefore, we successfully integrate CPN and GAs to obtain an optimal schedule with the deadlock and re-entrant problems for the flexible process of the cluster tool.

This article investigates a change in the structuring of work time, using a natural experiment to test whether participation in a corporate initiative (Results Only Work Environment; ROWE) predicts corresponding changes in health-related outcomes. Drawing on job strain and stress process models, we theorize greater schedule control and reduced work-family conflict as key mechanisms linking this initiative with health outcomes. Longitudinal survey data from 659 employees at a corporate headquarters shows that ROWE predicts changes in health-related behaviors, including almost an extra hour of sleep on work nights. Increasing employees’ schedule control and reducing their work-family conflict are key mechanisms linking the ROWE innovation with changes in employees’ health behaviors; they also predict changes in well-being measures, providing indirect links between ROWE and well-being. This study demonstrates that organizational changes in the structuring of time can promote employee wellness, particularly in terms of prevention behaviors. PMID:22144731
Application of decentralized cooperative problem solving in dynamic flexible scheduling

The object of this study is to discuss an intelligent solution to the problem of task-allocation in shop floor scheduling. For this purpose, the technique of distributed artificial intelligence (DAI) is applied. Intelligent agents (IAs) are used to realize decentralized cooperation, and negotiation is realized by using message passing based on the contract net model. Multiple agents, such as manager agents, workcell agents, and workstation agents, make game-like decisions based on multiple criteria evaluations. This procedure of decentralized cooperative problem solving makes local scheduling possible. And by integrating such multiple local schedules, dynamic flexible scheduling for the whole shop floor production can be realized.

This paper describes a computing environment which supports computer-based scientific research work. Key features include support for automatic distributed scheduling and execution and computer-based scientific experimentation. A new flexible and extensible scheduling technique that is responsive to a user`s scheduling constraints, such as the ordering of program results and the specification of task assignments and processor utilization levels, is presented. An easy-to-use constraint language for specifying scheduling constraints, based on the relational database query language SQL, is described along with a search-based algorithm for fulfilling these constraints. A set of performance studies show that the environment can schedule and executemore » program graphs on a network of workstations as the user requests. A method for automatically generating computer-based scientific experiments is described. Experiments provide a concise method of specifying a large collection of parameterized program executions. The environment achieved significant speedups when executing experiments; for a large collection of scientific experiments an average speedup of 3.4 on an average of 5.5 scheduled processors was obtained.« less

astroplan is a flexible toolbox for observation planning and scheduling. It is powered by Astropy (ascl:1304.002); it works for Python beginners and new observers, and is powerful enough for observatories preparing nightly and long-term schedules as well. It calculates rise/set/meridian transit times, alt/az positions for targets at observatories anywhere on Earth, and offers built-in plotting convenience functions for standard observation planning plots (airmass, parallactic angle, sky maps). It can also determine the observability of sets of targets given an arbitrary set of constraints (i.e., altitude, airmass, moon separation/illumination, etc.).
Quality Assurance Specifications for Planetary Protection Assays
NASA Astrophysics Data System (ADS)
Baker, Amy
As the European Space Agency planetary protection (PP) activities move forward to support the ExoMars and other planetary missions, it will become necessary to increase staffing of labo-ratories that provide analyses for these programs. Standardization of procedures, a comprehen-sive quality assurance program, and unilateral training of personnel will be necessary to ensure that the planetary protection goals and schedules are met. The PP Quality Assurance/Quality Control (QAQC) program is designed to regulate and monitor procedures performed by labora-tory personnel to ensure that all work meets data quality objectives through the assembly and launch process. Because personnel time is at a premium and sampling schedules are often de-pendent on engineering schedules, it is necessary to have flexible staffing to support all sampling requirements. The most productive approach to having a competent and flexible work force is to establish well defined laboratory procedures and training programs that clearly address the needs of the program and the work force. The quality assurance specification for planetary protection assays has to ensure that labora-tories and associated personnel can demonstrate the competence to perform assays according to the applicable standard AD4. Detailed subjects included in the presentation are as follows: • field and laboratory control criteria • data reporting • personnel training requirements and certification • laboratory audit criteria. Based upon RD2 for primary and secondary validation and RD3 for data quality objectives, the QAQC will provide traceable quality assurance safeguards by providing structured laboratory requirements for guidelines and oversight including training and technical updates, standardized documentation, standardized QA/QC checks, data review and data archiving.

Multiagent scheduling method with earliness and tardiness objectives in flexible job shops.
Wu, Zuobao; Weng, Michael X
2005-04-01
Flexible job-shop scheduling problems are an important extension of the classical job-shop scheduling problems and present additional complexity. Such problems are mainly due to the existence of a considerable amount of overlapping capacities with modern machines. Classical scheduling methods are generally incapable of addressing such capacity overlapping. We propose a multiagent scheduling method with job earliness and tardiness objectives in a flexible job-shop environment. The earliness and tardiness objectives are consistent with the just-in-time production philosophy which has attracted significant attention in both industry and academic community. A new job-routing and sequencing mechanism is proposed. In this mechanism, two kinds of jobs are defined to distinguish jobs with one operation left from jobs with more than one operation left. Different criteria are proposed to route these two kinds of jobs. Job sequencing enables to hold a job that may be completed too early. Two heuristic algorithms for job sequencing are developed to deal with these two kinds of jobs. The computational experiments show that the proposed multiagent scheduling method significantly outperforms the existing scheduling methods in the literature. In addition, the proposed method is quite fast. In fact, the simulation time to find a complete schedule with over 2000 jobs on ten machines is less than 1.5 min.

Objectives 12 h shifts are becoming increasingly common for hospital nurses but there is concern that long shifts adversely affect nurses’ well-being, job satisfaction and intention to leave their job. The aim of this study is to examine the association between working long shifts and burnout, job dissatisfaction, dissatisfaction with work schedule flexibility and intention to leave current job among hospital nurses. Methods Cross-sectional survey of 31 627 registered nurses in 2170 general medical/surgical units within 488 hospitals across 12 European countries. Results Nurses working shifts of ≥12 h were more likely than nurses working shorter hours (≤8) to experience burnout, in terms of emotional exhaustion (adjusted OR (aOR)=1.26; 95% CI 1.09 to 1.46), depersonalisation (aOR=1.21; 95% CI 1.01 to 1.47) and low personal accomplishment (aOR=1.39; 95% CI 1.20 to 1.62). Nurses working shifts of ≥12 h were more likely to experience job dissatisfaction (aOR=1.40; 95% CI 1.20 to 1.62), dissatisfaction with work schedule flexibility (aOR=1.15; 95% CI 1.00 to 1.35) and report intention to leave their job due to dissatisfaction (aOR=1.29; 95% CI 1.12 to 1.48). Conclusions Longer working hours for hospital nurses are associated with adverse outcomes for nurses. Some of these adverse outcomes, such as high burnout, may pose safety risks for patients as well as nurses. PMID:26359284

Women's lives are marked by complex work and family routines - routines that have implications for their children's health. Prior research suggests a link between mothers' work hours and their children's weight, but few studies investigate the child health implications of increasingly common work arrangements, such as telecommuting and flexible work schedules. We examine whether changes in mothers' work arrangements are associated with changes in adolescents' weight, physical activity, and sedentary behavior using longitudinal data and fixed effects models to better account for mothers' social selection in to different work arrangements and children's underlying preferences. With data from the National Longitudinal Study of Adolescent to Adult Health ( N = 10,518), we find that changes in mothers' work arrangements are not significantly associated with adolescents' weight gain or physical activity but are significantly associated with adolescents' sedentary behavior. Adolescents' sedentary behavior declines when mothers become more available after school and increases when mothers work more hours or become unemployed. In sum, after accounting for unobserved, stable traits, including mothers' selection into jobs with more or less flexibility, mothers' work arrangements are most strongly associated with adolescents' sedentary behavior.

The aim of this study was to investigate the effect of work-time influence on stress and energy, work-family conflicts, lifestyle factors, and biomarkers of cardiovascular disease risk. The study was a quasi-experimental intervention study with a one-year follow-up among eldercare workers (baseline: n = 309; follow-up: n = 297). The nine work units in the intervention group designed their own intervention. We categorized these work units into three subgroups according to the interventions that they initiated: (A) self-scheduling via a computer program (n = 35), (B) setting up a task group that developed a questionnaire on work-time preference and participated in a one-day course on flexible working hours with the intention to increase employee influence on the fixed rota (n = 62), and (C) discussions of how employee work-time influence could be increased (n = 25). These subgroups were compared with a reference group consisting of ten work units (n = 187). Data consisted of questionnaires, blood samples, and measurements of waist and hip circumference. The employees in subgroup A became increasingly involved in the planning of their own work schedule. Nevertheless, we found no effect on health and well-being attributable to the intervention. The introduction of self-scheduling can successfully increase employee work-time influence. Yet, this study does not support the theory that increased work-time influence leads to better health and well-being.

The Robert C. Byrd Green Bank Telescope (GBT) is implementing a new Dynamic Scheduling System (DSS) designed to maximize the observing efficiency of the telescope while ensuring that none of the flexibility and ease of use of the GBT is harmed and that the data quality of observations is not adversely affected. To accomplish this, the GBT DSS is implementing a dynamic scheduling system which schedules observers, rather than running scripts. The DSS works by breaking each project into one or more sessions which have associated observing criteria such as RA, Dec, and frequency. Potential observers may also enter dates when members of their team will not be available for either on-site or remote observing. The scheduling algorithm uses those data, along with the predicted weather, to determine the most efficient schedule for the GBT. The DSS provides all observers at least 24 hours notice of their upcoming observing. In the uncommon (< 20%) case where the actual weather does not match the predictions, a backup project, chosen from the database, is run instead. Here we give an overview of the GBT DSS project, including the ranking and scheduling algorithms for the sessions, the scheduling probabilities generation, the web framework for the system, and an overview of the results from the beta testing which were held from June - September, 2008.

Solving a real-world problem using an evolving heuristically driven schedule builder.
Hart, E; Ross, P; Nelson, J
1998-01-01
This work addresses the real-life scheduling problem of a Scottish company that must produce daily schedules for the catching and transportation of large numbers of live chickens. The problem is complex and highly constrained. We show that it can be successfully solved by division into two subproblems and solving each using a separate genetic algorithm (GA). We address the problem of whether this produces locally optimal solutions and how to overcome this. We extend the traditional approach of evolving a "permutation + schedule builder" by concentrating on evolving the schedule builder itself. This results in a unique schedule builder being built for each daily scheduling problem, each individually tailored to deal with the particular features of that problem. This results in a robust, fast, and flexible system that can cope with most of the circumstances imaginable at the factory. We also compare the performance of a GA approach to several other evolutionary methods and show that population-based methods are superior to both hill-climbing and simulated annealing in the quality of solutions produced. Population-based methods also have the distinct advantage of producing multiple, equally fit solutions, which is of particular importance when considering the practical aspects of the problem.

With the rapid development of mobile live business, transcoding HD video is often a challenge for mobile devices due to their limited processing capability and bandwidth-constrained network connection. For live service providers, it's wasteful for resources to delay lots of transcoding server because some of them are free to work sometimes. To deal with this issue, this paper proposed an Openstack-based flexible transcoding framework to achieve real-time video adaption for mobile device and make computing resources used efficiently. To this end, we introduced a special method of video stream splitting and VMs resource scheduling based on access pressure prediction,which is forecasted by an AR model.

In general, both machines and human resources are needed for processing a job on production floor. However, most classical scheduling problems have ignored the possible constraint caused by availability of workers and have considered only machines as a limited resource. In addition, along with production technology development, routing flexibility appears as a consequence of high product variety and medium demand for each product. Routing flexibility is caused by capability of machines that offers more than one machining process. This paper presents a method to address scheduling problem constrained by both machines and workers, considering routing flexibility. Scheduling in a Dual-Resource Constrained shop is categorized as NP-hard problem that needs long computational time. Meta-heuristic approach, based on Genetic Algorithm, is used due to its practical implementation in industry. Developed Genetic Algorithm uses indirect chromosome representative and procedure to transform chromosome into Gantt chart. Genetic operators, namely selection, elitism, crossover, and mutation are developed to search the best fitness value until steady state condition is achieved. A case study in a manufacturing SME is used to minimize tardiness as objective function. The algorithm has shown 25.6% reduction of tardiness, equal to 43.5 hours.
Completable scheduling: An integrated approach to planning and scheduling

The planning problem has traditionally been treated separately from the scheduling problem. However, as more realistic domains are tackled, it becomes evident that the problem of deciding on an ordered set of tasks to achieve a set of goals cannot be treated independently of the problem of actually allocating resources to the tasks. Doing so would result in losing the robustness and flexibility needed to deal with imperfectly modeled domains. Completable scheduling is an approach which integrates the two problems by allowing an a priori planning module to defer particular planning decisions, and consequently the associated scheduling decisions, until execution time. This allows a completable scheduling system to maximize plan flexibility by allowing runtime information to be taken into consideration when making planning and scheduling decision. Furthermore, through the criteria of achievability placed on deferred decision, a completable scheduling system is able to retain much of the goal-directedness and guarantees of achievement afforded by a priori planning. The completable scheduling approach is further enhanced by the use of contingent explanation-based learning, which enables a completable scheduling system to learn general completable plans from example and improve its performance through experience. Initial experimental results show that completable scheduling outperforms classical scheduling as well as pure reactive scheduling in a simple scheduling domain.

BASS 4, a computer program for the design and evaluation of workings hours, is an example of an ergonomics-based software tool that can be used by safety practitioners at the shop floor with regard to legal, ergonomic, and economic criteria. Based on experiences with this computer program, a less sophisticated Working-Hours-Risk Index for assessing the quality of work schedules (including flexible work hours) to indicate risks to health and wellbeing has been developed to provide a quick and easy applicable tool for legally required risk assessments. The results of a validation study show that this risk index seems to be a promising indicator for predicting risks of health complaints and wellbeing. The purpose of the Risk Index is to simplify the evaluation process at the shop floor and provide some more general information about the quality of a work schedule that can be used for triggering preventive interventions. Such a risk index complies with practitioners' expectations and requests for easy, useful, and valid instruments.
A genetic algorithm-based approach to flexible flow-line scheduling with variable lot sizes.

Genetic algorithms (GAs) have been used widely for such combinatorial optimization problems as the traveling salesman problem (TSP), the quadratic assignment problem (QAP), and job shop scheduling. In all of these problems there is usually a well defined representation which GA's use to solve the problem. We present a novel approach for solving two related problems-lot sizing and sequencing-concurrently using GAs. The essence of our approach lies in the concept of using a unified representation for the information about both the lot sizes and the sequence and enabling GAs to evolve the chromosome by replacing primitive genes with good building blocks. In addition, a simulated annealing procedure is incorporated to further improve the performance. We evaluate the performance of applying the above approach to flexible flow line scheduling with variable lot sizes for an actual manufacturing facility, comparing it to such alternative approaches as pair wise exchange improvement, tabu search, and simulated annealing procedures. The results show the efficacy of this approach for flexible flow line scheduling.

12 h shifts are becoming increasingly common for hospital nurses but there is concern that long shifts adversely affect nurses' well-being, job satisfaction and intention to leave their job. The aim of this study is to examine the association between working long shifts and burnout, job dissatisfaction, dissatisfaction with work schedule flexibility and intention to leave current job among hospital nurses. Cross-sectional survey of 31,627 registered nurses in 2170 general medical/surgical units within 488 hospitals across 12 European countries. Nurses working shifts of ≥12 h were more likely than nurses working shorter hours (≤8) to experience burnout, in terms of emotional exhaustion (adjusted OR (aOR)=1.26; 95% CI 1.09 to 1.46), depersonalisation (aOR=1.21; 95% CI 1.01 to 1.47) and low personal accomplishment (aOR=1.39; 95% CI 1.20 to 1.62). Nurses working shifts of ≥12 h were more likely to experience job dissatisfaction (aOR=1.40; 95% CI 1.20 to 1.62), dissatisfaction with work schedule flexibility (aOR=1.15; 95% CI 1.00 to 1.35) and report intention to leave their job due to dissatisfaction (aOR=1.29; 95% CI 1.12 to 1.48). Longer working hours for hospital nurses are associated with adverse outcomes for nurses. Some of these adverse outcomes, such as high burnout, may pose safety risks for patients as well as nurses.

Multi-mode operation and transient stability are two problems that significantly affect flexible microgrid (MG). This paper proposes a multi-mode operation control strategy for flexible MG based on a three-layer hierarchical structure. The proposed structure is composed of autonomous, cooperative, and scheduling controllers. Autonomous controller is utilized to control the performance of the single micro-source inverter. An adaptive sliding-mode direct voltage loop and an improved droop power loop based on virtual negative impedance are presented respectively to enhance the system disturbance-rejection performance and the power sharing accuracy. Cooperative controller, which is composed of secondary voltage/frequency control and phase synchronization control, is designed to eliminate the voltage/frequency deviations produced by the autonomous controller and prepare for grid connection. Scheduling controller manages the power flow between the MG and the grid. The MG with the improved hierarchical control scheme can achieve seamless transitions from islanded to grid-connected mode and have a good transient performance. In addition the presented work can also optimize the power quality issues and improve the load power sharing accuracy between parallel VSIs. Finally, the transient performance and effectiveness of the proposed control scheme are evaluated by theoretical analysis and simulation results. Copyright © 2015 ISA. Published by Elsevier Ltd.

Many patients with breast cancer work for pay at the time of their diagnosis, and the treatment plan may threaten their livelihood. Understanding work experiences in a contemporary population-based sample is necessary to inform initiatives to reduce the burden of cancer care. Women who were 20 to 79 years old and had been diagnosed with stage 0 to II breast cancer, as reported to the Georgia and Los Angeles Surveillance, Epidemiology, and End Results registries in 2014-2015, were surveyed. Of the 3672 eligible women, 2502 responded (68%); 1006 who reported working before their diagnosis were analyzed. Multivariate models evaluated correlates of missing work for >1 month and stopping work altogether versus missing work for ≤1 month. In this diverse sample, most patients (62%) underwent lumpectomy; 16% underwent unilateral mastectomy (8% with reconstruction); and 23% underwent bilateral mastectomy (19% with reconstruction). One-third (33%) received chemotherapy. Most (84%) worked full-time before their diagnosis; however, only 50% had paid sick leave, 39% had disability benefits, and 38% had flexible work schedules. Surgical treatment was strongly correlated with missing >1 month of work (odds ratio [OR] for bilateral mastectomy with reconstruction vs lumpectomy, 7.8) and with stopping work altogether (OR for bilateral mastectomy with reconstruction vs lumpectomy, 3.1). Chemotherapy receipt (OR for missing >1 month, 1.3; OR for stopping work altogether, 3.9) and race (OR for missing >1 month for blacks vs whites, 2.0; OR for stopping work altogether for blacks vs whites, 1.7) also correlated. Those with paid sick leave were less likely to stop working (OR, 0.5), as were those with flexible schedules (OR, 0.3). Working patients who received more aggressive treatments were more likely to experience substantial employment disruptions.

Constraint Maintenance with Preferences and Underlying Flexible Solution

This paper describes an aspect of the constraint reasoning mechanism. that is part of a ground planning system slated to be used for the Mars Exploration Rovers mission, where two rovers are scheduled to land on Mars in January of 2003. The planning system combines manual planning software from JPL with an automatic planning/scheduling system from NASA Ames Research Center, and is designed to be used in a mixed-initiative mode. Among other things, this means that after a plan has been produced, the human operator can perform extensive modifications under the supervision of the automated. system. For each modification to an activity, the automated system must adjust other activities as needed to ensure that constraints continue to be satisfied. Thus, the system must accommodate change in an interactive setting. Performance is of critical importance for interactive use. This is achieved by maintaining an underlying flexible solution to the temporal constraints, while the system presents a fixed schedule to the user. Adjustments are then a matter of constraint propagation rather than completely re-solving the problem. However, this begs the important question of which fixed schedule (among the ones sanctioned by the underlying flexible solution) should be presented to the user.Our approach uses least-change and other preferences as a prism through which the user views the flexible solution.
Relieving the Time Squeeze? Effects of a White-Collar Workplace Change on Parents
Hill, Rachelle; Tranby, Eric; Kelly, Erin; Moen, Phyllis
2013-01-01
Employed parents perceive a time squeeze even as trends from the 1960s show they are spending more time with their children. Work conditions (e.g., hours and schedule control) would seem to affect both parents’ time with children and perceived time squeeze, but most studies rely on cross-sectional data that do not establish causality. The authors examined the effects of the introduction of a workplace flexibility initiative (Results Only Work Environment [ROWE]) on changes in mothers’ and fathers’ perceptions of the adequacy of their time with children and actual time spent with children (N = 225). Baseline data show the importance of work conditions for parents’ sense of perceived time adequacy. Panel data show that mothers (but not fathers) in ROWE report increased schedule control and improved time adequacy, but no change in actual time spent with children, except that ROWE increases evening meals with children for mothers sharing few meals at baseline.

Employees working for office-cleaning companies are directly affected by the growing competition in this sector. They face a heavier workload and heightened psychological pressure. A majority of these workers are less qualified women working part-time, with flexible and inconvenient schedules. The objective of the study is to highlight the workers' strategies to deal with fast work, schedule requirements and the consequent difficulties to reconcile their professional and private life commitments. This study is based on in-depth interviews. One hundred and twenty-five male and female workers responsible for cleaning offices. The themes generated from the results highlight a continued deterioration in working conditions in this sector. They also show that even approximate respect of the theoretical workload as calculated by the sub-contractor and the client company mainly depends on the workers' subjective strategies to accommodate increasingly fragmented work hours with their private lives. In conclusion, since these individual strategies are not enough to make up for the deterioration in work conditions, improving them requires sub-contractors and client companies to agree on organisational arrangements that take into account the reality of the employees' lives.

Development of An Intelligent Flight Propulsion Control System

Calise, A. J.; Rysdyk, R. T.; Leonhardt, B. K.
1999-01-01
The initial design and demonstration of an Intelligent Flight Propulsion and Control System (IFPCS) is documented. The design is based on the implementation of a nonlinear adaptive flight control architecture. This initial design of the IFPCS enhances flight safety by using propulsion sources to provide redundancy in flight control. The IFPCS enhances the conventional gain scheduled approach in significant ways: (1) The IFPCS provides a back up flight control system that results in consistent responses over a wide range of unanticipated failures. (2) The IFPCS is applicable to a variety of aircraft models without redesign and,(3) significantly reduces the laborious research and design necessary in a gain scheduled approach. The control augmentation is detailed within an approximate Input-Output Linearization setting. The availability of propulsion only provides two control inputs, symmetric and differential thrust. Earlier Propulsion Control Augmentation (PCA) work performed by NASA provided for a trajectory controller with pilot command input of glidepath and heading. This work is aimed at demonstrating the flexibility of the IFPCS in providing consistency in flying qualities under a variety of failure scenarios. This report documents the initial design phase where propulsion only is used. Results confirm that the engine dynamics and associated hard nonlineaaities result in poor handling qualities at best. However, as demonstrated in simulation, the IFPCS is capable of results similar to the gain scheduled designs of the NASA PCA work. The IFPCS design uses crude estimates of aircraft behaviour. The adaptive control architecture demonstrates robust stability and provides robust performance. In this work, robust stability means that all states, errors, and adaptive parameters remain bounded under a wide class of uncertainties and input and output disturbances. Robust performance is measured in the quality of the tracking. The results demonstrate the flexibility of the IFPCS architecture and the ability to provide robust performance under a broad range of uncertainty. Robust stability is proved using Lyapunov like analysis. Future development of the IFPCS will include integration of conventional control surfaces with the use of propulsion augmentation, and utilization of available lift and drag devices, to demonstrate adaptive control capability under a greater variety of failure scenarios. Further work will specifically address the effects of actuator saturation.
The French 35-hour workweek: a wide-ranging social change.
Prunier-Poulmaire, S; Gadbois, C
2001-12-01
The reduction of the legal working week to 35 hours in France has generated wide-ranging social change. We examine the resulting changes in working-time patterns as well as their repercussions on the use of the time gained and on the quality of life and health. To compensate the reduction in the length of the working week, companies have modified the working-time patterns, by extending operation time (shiftwork, atypical schedules) and by matching the on-site workforce to production requirements (flexible working hours). They have sought to make more efficient use of working time: job intensification or job compression. The effects on the off-the-job life and health are linked to the shiftwork and atypical schedules designed to increase the company's operating time, and adjustments to the company's need for flexibilization impose working time/free time patterns that are at odds with biological rhythms and social life patterns. Changes to working-time patterns have unexpected consequences for work organization: heightened difficulties for the individual and the crew. These changes may generate a range of health problems related to overwork and stress. The way some companies have adapted may call into question the usefulness of work done by employees, thus damaging their social identity and mental well-being.
Solving the flexible job shop problem by hybrid metaheuristics-based multiagent model

Nouri, Houssem Eddine; Belkahla Driss, Olfa; Ghédira, Khaled
2018-03-01
The flexible job shop scheduling problem (FJSP) is a generalization of the classical job shop scheduling problem that allows to process operations on one machine out of a set of alternative machines. The FJSP is an NP-hard problem consisting of two sub-problems, which are the assignment and the scheduling problems. In this paper, we propose how to solve the FJSP by hybrid metaheuristics-based clustered holonic multiagent model. First, a neighborhood-based genetic algorithm (NGA) is applied by a scheduler agent for a global exploration of the search space. Second, a local search technique is used by a set of cluster agents to guide the research in promising regions of the search space and to improve the quality of the NGA final population. The efficiency of our approach is explained by the flexible selection of the promising parts of the search space by the clustering operator after the genetic algorithm process, and by applying the intensification technique of the tabu search allowing to restart the search from a set of elite solutions to attain new dominant scheduling solutions. Computational results are presented using four sets of well-known benchmark literature instances. New upper bounds are found, showing the effectiveness of the presented approach.

2011-12-01
With rapid growth of Internet applications, supporting differentiated service and enlarging system capacity have been new tasks for next generation access system. In recent years, research in OFDMA Passive Optical Networks (PON) has experienced extraordinary development as for its large capacity and flexibility in scheduling. Although much work has been done to solve hardware layer obstacles for OFDMA PON, scheduling algorithm on OFDMA PON system is still under primary discussion. In order to support QoS service on OFDMA PON system, a novel dynamic wavelength bandwidth allocation (DWBA) algorithm is proposed in this paper. Per-stream QoS service is supported in this algorithm. Through simulation, we proved our bandwidth allocation algorithm performs better in bandwidth utilization and differentiate service support.

Administration of graduate medical education programs has become more difficult as compliance with ACGME work guidelines has assumed increased importance. These guidelines have caused many changes in the resident work environment, including the emergence of complicated cross-cover arrangements. Many participating residents (each with his or her own individual scheduling requirements) usually generate these schedules. Accordingly, schedules are often not submitted in a timely fashion and they may not be in compliance with the ACGME guidelines for maximum on-call assignments and mandatory days off. Our objective was the establishment of a Web-based system that guides residents in creating on-call schedules that follow ACGME guidelines while still allowing maximum flexibility -- thus allowing each resident to maintain an internal locus of control. A versatile and scalable system with password-protected user (resident) and administrator interfaces was created. An entire academic year is included, and past months and years are automatically archived. The residents log on within the first 15 days of the preceding month and choose their positions in a schedule template. They then make adjustments while receiving immediate summary feedback on compliance with ACGME guidelines. The schedule is electronically submitted to the educational administrator for final approval. If a cross-cover system is required, the program automatically generates an optimal schedule using both of the approved participating service schedules. The residents then have an additional five-day period to make adjustments in the cross-cover schedule while still receiving compliance feedback. The administrator again provides final approval electronically. The communication interface automatically pages or e-mails the residents when schedules are updated or approved. Since the information exists in a relational database, simple reporting tools are included to extract the information necessary to generate records for institutional GME management. Implementation of this program has been met with great enthusiasm from the institutional stakeholders. Specifically, residents have embraced the ability to directly control their schedules and have gained appreciation for the regulatory matrix in which they function. Institutional administrators have praised the improvement in compliance and the ease of documentation. We anticipate that the system will also meet with approval from reviewing regulatory bodies, as it generates and stores accurate information about the resident work environment. This program is robust and versatile enough to be modified for any GME training program in the country.
HOROPLAN: computer-assisted nurse scheduling using constraint-based programming.

Nurse scheduling is a difficult and time consuming task. The schedule has to determine the day to day shift assignments of each nurse for a specified period of time in a way that satisfies the given requirements as much as possible, taking into account the wishes of nurses as closely as possible. This paper presents a constraint-based, artificial intelligence approach by describing a prototype implementation developed with the Charme language and the first results of its use in the Rouen University Hospital. Horoplan implements a non-cyclical constraint-based scheduling, using some heuristics. Four levels of constraints were defined to give a maximum of flexibility: French level (e.g. number of worked hours in a year), hospital level (e.g. specific day-off), department level (e.g. specific shift) and care unit level (e.g. specific pattern for week-ends). Some constraints must always be verified and can not be overruled and some constraints can be overruled at a certain cost. Rescheduling is possible at any time specially in case of an unscheduled absence.
A cross-domain communication resource scheduling method for grid-enabled communication networks

Zheng, Xiangquan; Wen, Xiang; Zhang, Yongding
2011-10-01
To support a wide range of different grid applications in environments where various heterogeneous communication networks coexist, it is important to enable advanced capabilities in on-demand and dynamical integration and efficient co-share with cross-domain heterogeneous communication resource, thus providing communication services which are impossible for single communication resource to afford. Based on plug-and-play co-share and soft integration with communication resource, Grid-enabled communication network is flexibly built up to provide on-demand communication services for gird applications with various requirements on quality of service. Based on the analysis of joint job and communication resource scheduling in grid-enabled communication networks (GECN), this paper presents a cross multi-domain communication resource cooperatively scheduling method and describes the main processes such as traffic requirement resolution for communication services, cross multi-domain negotiation on communication resource, on-demand communication resource scheduling, and so on. The presented method is to afford communication service capability to cross-domain traffic delivery in GECNs. Further research work towards validation and implement of the presented method is pointed out at last.

Can varying the number of teams in a shift schedule constitute a preventive strategy?
Jeppesen, Hans Jeppe; Kleiven, Magnar; Bøggild, Henrik
2004-12-01
The study examines the implications for shiftworkers of applying different numbers of teams in the organization of shiftwork. The participating operators came from five different companies applying continuous shift rotation systems. The companies shared the same product organization and a common corporate culture belonging to the same multinational company. Each company had a shift system consisting of four, five or six teams, with the proportion of shifts outside day work decreasing as the number of teams increased. Questionnaire and documentary data were used as data sources. Operators in systems with additional teams had more daywork but also more irregular working hours due to both overtime and schedule changes. Operators using six teams used fewer social compensation strategies. Operators in four teams were most satisfied with their work hours. Satisfaction with the time available for various social activities outside work varied inconsistently between the groups. In rotating systems the application of more teams reduces the number of shifts outside day work. This apparent improvement for shiftworkers was counteracted by a concomitant irregularity produced by greater organizational requirements for flexibility. The balance of this interaction was found to have a critical impact on employees.

The Development of Patient Scheduling Groups for an Effective Appointment System
2016-01-01
Summary Background Patient access to care and long wait times has been identified as major problems in outpatient delivery systems. These aspects impact medical staff productivity, service quality, clinic efficiency, and health-care cost. Objectives This study proposed to redesign existing patient types into scheduling groups so that the total cost of clinic flow and scheduling flexibility was minimized. The optimal scheduling group aimed to improve clinic efficiency and accessibility. Methods The proposed approach used the simulation optimization technique and was demonstrated in a Primary Care physician clinic. Patient type included, emergency/urgent care (ER/UC), follow-up (FU), new patient (NP), office visit (OV), physical exam (PE), and well child care (WCC). One scheduling group was designed for this physician. The approach steps were to collect physician treatment time data for each patient type, form the possible scheduling groups, simulate daily clinic flow and patient appointment requests, calculate costs of clinic flow as well as appointment flexibility, and find the scheduling group that minimized the total cost. Results The cost of clinic flow was minimized at the scheduling group of four, an 8.3% reduction from the group of one. The four groups were: 1. WCC, 2. OV, 3. FU and ER/UC, and 4. PE and NP. The cost of flexibility was always minimized at the group of one. The total cost was minimized at the group of two. WCC was considered separate and the others were grouped together. The total cost reduction was 1.3% from the group of one. Conclusions This study provided an alternative method of redesigning patient scheduling groups to address the impact on both clinic flow and appointment accessibility. Balance between them ensured the feasibility to the recognized issues of patient service and access to care. The robustness of the proposed method on the changes of clinic conditions was also discussed. PMID:27081406

This study aimed to understand parents' evaluations of the way they integrated work-family demands to manage food and eating. Employed, low/moderate-income, urban, U.S., Black, White, and Latino mothers (35) and fathers (34) participated in qualitative interviews exploring work and family conditions and spillover, food roles, and food-choice coping and family-adaptive strategies. Parents expressed a range of evaluations from overall satisfaction to overall dissatisfaction as well as dissatisfaction limited to work, family life, or daily schedule. Evaluation criteria differed by gender. Mothers evaluated satisfaction on their ability to balance work and family demands through flexible home and work conditions, while striving to provide healthy meals for their families. Fathers evaluated satisfaction on their ability to achieve schedule stability and participate in family meals, while meeting expectations to contribute to food preparation. Household, and especially work structural conditions, often served as sizeable barriers to parents fulfilling valued family food roles. These relationships highlight the critical need to consider the intersecting influences of gender and social structure as influences on adults' food choices and dietary intake and to address the challenges of work and family integration among low income employed parents as a way to promote family nutrition in a vulnerable population.

Employed, low/moderate-income, urban, U.S., Black, White, and Latino mothers (35) and fathers (34) participated in qualitative interviews exploring work and family conditions and spillover, food roles, and food-choice coping and family-adaptive strategies. Parents expressed a range of evaluations from overall satisfaction to overall dissatisfaction as well as dissatisfaction limited to work, family life, or daily schedule. Evaluation criteria differed by gender. Mothers evaluated satisfaction on their ability to balance work and family demands through flexible home and work conditions, while striving to provide healthy meals for their families. Fathers evaluated satisfaction on their ability to achieve schedule stability and participate in family meals, while meeting expectations to contribute to food preparation. Household, and especially work structural conditions, often served as sizeable barriers to parents fulfilling valued family food roles. These relationships highlight the critical need to consider the intersecting influences of gender and social structure as influences on adults’ food choices and dietary intake and to address the challenges of work and family integration among low income employed parents as a way to promote family nutrition in a vulnerable population.

The role of the government in work-family conflict.
Boushey, Heather
2011-01-01
The foundations of the major federal policies that govern today's workplace were put in place during the 1930s, when most families had a stay-at-home caregiver who could tend to the needs of children, the aged, and the sick. Seven decades later, many of the nation's workplace policies are in need of major updates to reflect the realities of the modern workforce. American workers, for example, typically have little or no control over their work hours and schedules; few have a right to job-protected access to paid leave to care for a family member. Heather Boushey examines three types of work-family policies that affect work-family conflict and that are in serious need of repair--those that govern hours worked and workplace equity, those that affect the ability of workers to take time off from work because their families need care, and those that govern the outsourcing of family care when necessary. In each case Boushey surveys new programs currently on the policy agenda, assesses their effectiveness, and considers the extent to which they can be used as models for a broader federal program. Boushey looks, for example, at a variety of pilot and experimental programs that have been implemented both by private employers and by federal, state, and local governments to provide workers with flexible working hours. Careful evaluations of these programs show that several can increase scheduling flexibility without adversely affecting employers. Although few Americans have access to paid family and medical leave to attend to family needs, most believe that businesses should be required to provide paid leave to all workers. Boushey notes that several states are moving in that direction. Again, careful evaluations show that these experimental programs are successful for both employers and employees. National programs to address child and elder care do not yet exist. The most comprehensive solution on the horizon is the universal prekindergarten programs offered by a few states, most often free of charge, for children aged three and four.
Dynamic Multiple Work Stealing Strategy for Flexible Load Balancing
NASA Astrophysics Data System (ADS)
Adnan; Sato, Mitsuhisa
Lazy-task creation is an efficient method of overcoming the overhead of the grain-size problem in parallel computing. Work stealing is an effective load balancing strategy for parallel computing. In this paper, we present dynamic work stealing strategies in a lazy-task creation technique for efficient fine-grain task scheduling. The basic idea is to control load balancing granularity depending on the number of task parents in a stack. The dynamic-length strategy of work stealing uses run-time information, which is information on the load of the victim, to determine the number of tasks that a thief is allowed to steal. We compare it with the bottommost first work stealing strategy used in StackThread/MP, and the fixed-length strategy of work stealing, where a thief requests to steal a fixed number of tasks, as well as other multithreaded frameworks such as Cilk and OpenMP task implementations. The experiments show that the dynamic-length strategy of work stealing performs well in irregular workloads such as in UTS benchmarks, as well as in regular workloads such as Fibonacci, Strassen's matrix multiplication, FFT, and Sparse-LU factorization. The dynamic-length strategy works better than the fixed-length strategy because it is more flexible than the latter; this strategy can avoid load imbalance due to overstealing.

Background Self-monitoring of blood pressure is common but guidance on how it should be carried out varies and it is currently unclear how such guidance is viewed. Aim To explore patients’ and healthcare professionals’ (HCPs) views and experiences of the use of different self-monitoring regimens to determine what is acceptable and feasible, and to inform future recommendations. Design and setting Thirteen focus groups and four HCP interviews were held, with a total of 66 participants (41 patients and 25 HCPs) from primary and secondary care with and without experience of self-monitoring. Method Standard and shortened self-monitoring protocols were both considered. Focus groups and interviews were recorded, transcribed verbatim, and analysed using the constant comparative method. Results Patients generally supported structured schedules but with sufficient flexibility to allow adaptation to individual routine. They preferred a shorter (3-day) schedule to longer (7-day) regimens. Although HCPs could describe benefits for patients of using a schedule, they were reluctant to recommend a specific schedule. Concerns surrounded the use of different schedules for diagnosis and subsequent monitoring. Appropriate education was seen as vital by all participants to enable a self-monitoring schedule to be followed at home. Conclusion There is not a ‘one size fits all approach’ to developing the optimum protocol from the perspective of users and those implementing it. An approach whereby patients are asked to complete the minimum number of readings required for accurate blood pressure estimation in a flexible manner seems most likely to succeed. Informative advice and guidance should incorporate such flexibility for patients and professionals alike. PMID:27381484

A criterion autoscheduler for long range planning
NASA Technical Reports Server (NTRS)
Sponsler, Jeffrey L.
1994-01-01
A constraint-based scheduling system called SPIKE is used to create long-term schedules for the Hubble Space Telescope. A meta-level scheduler called the Criterion Autoscheduler for Long range planning (CASL) was created to guide SPIKE's schedule generation according to the agenda of the planning scientists. It is proposed that sufficient flexibility exists in a schedule to allow high level planning heuristics to be applied without adversely affected crucial constraints such as spacecraft efficiency. This hypothesis is supported by test data which is described.

A Decentralized Scheduling Policy for a Dynamically Reconfigurable Production System
NASA Astrophysics Data System (ADS)
Giordani, Stefano; Lujak, Marin; Martinelli, Francesco
In this paper, the static layout of a traditional multi-machine factory producing a set of distinct goods is integrated with a set of mobile production units - robots. The robots dynamically change their work position to increment the product rate of the different typologies of products in respect to the fluctuations of the demands and production costs during a given time horizon. Assuming that the planning time horizon is subdivided into a finite number of time periods, this particularly flexible layout requires the definition and the solution of a complex scheduling problem, involving for each period of the planning time horizon, the determination of the position of the robots, i.e., the assignment to the respective tasks in order to minimize production costs given the product demand rates during the planning time horizon.
A manpower scheduling heuristic for aircraft maintenance application

This research studies a manpower scheduling for aircraft maintenance, focusing on in-flight food loading operation. A group of loading teams with flexible shifts is required to deliver and upload packaged meals from the ground kitchen to aircrafts in multiple trips. All aircrafts must be served within predefined time windows. The scheduling process takes into account of various constraints such as meal break allocation, multi-trip traveling and food exposure time limit. Considering the aircrafts movement and predefined maximum working hours for each loading team, the main objective of this study is to form an efficient roster by assigning a minimum number of loading teams to the aircrafts. We proposed an insertion based heuristic to generate the solutions in a short period of time for large instances. This proposed algorithm is implemented in various stages for constructing trips due to the presence of numerous constraints. The robustness and efficiency of the algorithm is demonstrated in computational results. The results show that the insertion heuristic more efficiently outperforms the company's current practice.

This article explores whether mothers’ perceived control over their own workplace flexibility options has any relationship to their satisfaction with their husbands’ contributions to household labor in the United States. We hypothesize that flexibility enhances their ability to more adeptly engage in role management in multiple life areas, thus enabling them to be more satisfied with their partners’ domestic input as well. We use a unique data set of 1,078 randomly sampled women involved in mothers’ organizations that generally attract members based on their current level of participation in the paid labor market. We then link nine distinct workplace flexibility policies with mothers’ satisfaction related to their husbands’ participation in all household tasks, as well as a subset of female-typed tasks. We find that across both arrays of tasks, mothers with more perceived control over work-related schedule predictability and those that had the ability to secure employment again after an extended break had higher levels of satisfaction with their husbands’ participation in household labor. In addition, short-term time off to address unexpected needs was important for all tasks considered together only.
Teleworkers with disabilities: characteristics and accommodation use.
Linden, Maureen; Milchus, Karen
2014-01-01
The prevalence of telework among people with disabilities is not as great as the general population, despite the accommodative benefits of telework. This study of employment and accommodation use patterns of people with disabilities investigates relationships between functional abilities, work location and nature, and accommodation use. Currently employed subjects with disabilities were recruited from client lists of research, technical assistance, and service provision centers, as well as through over 100 social networking venues focused on individuals with disabilities. A national, cross-sectional survey was administered electronically. Details of accommodation use for 373 individuals were compared using Chi-Square distribution analysis. Those in white-collar and knowledge-based jobs were twice as likely to telework as other worker types, and teleworkers were twice as likely to use flexible scheduling. Only 47% of teleworkers reported telework as a job accommodation. Of those, 57% were satisfied with telework and 76% reported it as important to job task completion. Increased use of flexible scheduling, particularly among those who view telework as an accommodation, suggests the primary accommodative benefit of telework is to reduce pain and fatigue-related barriers to traditional employment. Relatively low satisfaction with telework suggests that it presents other employment-related barriers.
Constrained choices? Linking employees' and spouses' work time to health behaviors.
Fan, Wen; Lam, Jack; Moen, Phyllis; Kelly, Erin; King, Rosalind; McHale, Susan
2015-02-01
There are extensive literatures on work conditions and health and on family contexts and health, but less research asking how a spouse or partners' work conditions may affect health behaviors. Drawing on the constrained choices framework, we theorized health behaviors as a product of one's own time and spouses' work time as well as gender expectations. We examined fast food consumption and exercise behaviors using survey data from 429 employees in an Information Technology (IT) division of a U.S. Fortune 500 firm and from their spouses. We found fast food consumption is affected by men's work hours-both male employees' own work hours and the hours worked by husbands of women respondents-in a nonlinear way. The groups most likely to eat fast food are men working 50 h/week and women whose husbands work 45-50 h/week. Second, exercise is better explained if work time is conceptualized at the couple, rather than individual, level. In particular, neo-traditional arrangements (where husbands work longer than their wives) constrain women's ability to engage in exercise but increase odds of men exercising. Women in couples where both partners are working long hours have the highest odds of exercise. In addition, women working long hours with high schedule control are more apt to exercise and men working long hours whose wives have high schedule flexibility are as well. Our findings suggest different health behaviors may have distinct antecedents but gendered work-family expectations shape time allocations in ways that promote men's and constrain women's health behaviors. They also suggest the need to expand the constrained choices framework to recognize that long hours may encourage exercise if both partners are looking to sustain long work hours and that work resources, specifically schedule control, of one partner may expand the choices of the other.

Managing work life with systemic sclerosis.
Sandqvist, Gunnel; Hesselstrand, Roger; Scheja, Agneta; Håkansson, Carita
2012-02-01
To explore how individuals with SSc manage their work life. We conducted four focus group interviews, which included 17 patients currently working at least 20 h per week. The interviews were recorded and transcribed verbatim. The transcribed texts were analysed according to thematic content analysis. Relevant statements that generated preliminary categories were identified, after which themes and underlying subthemes were generated. The participants perceived their work role as being important, giving them a structure in everyday life and a sense of being useful members of society. Work and private life were interacting, and different adjustments had been developed to create a satisfactory balance of activities in daily life. Three themes emerged: adjustment of work situation, adapting to own resources and disclosing limitations. Reduced working hours, flexibility in the workplace concerning time schedule, room and tasks were all valuable adjustments, and were dependent on the employer, fellow workers as well as the individual's attitude towards informing employer and colleagues about his/her limitations. The participants had simplified and rationalized a lot of household chores and pointed to the importance of prioritizing meaningful activities, as well as the necessity of having time for rest and recovery. Reduced working hours, work flexibility and prioritizing meaningful activities and recovery were important factors in order to manage work life. Intervention, including problem-solving techniques and re-designing of activities in daily life, could be useful to coach individuals towards finding a balance in their work life.
I was never recruited: challenges in cross-Canada nurse mobility.

The internal migration of nurses within Canada has had limited study. This paper reports the results of a survey of registered nurses and licensed practical nurses who had migrated between the provinces and territories in Canada. Factors contributing to internal nurse mobility included seeking full-time work, opportunities for career advancement and flexible scheduling options. Few nurses received incentives to move between the provinces/territories to work. A number of challenges with internal migration are identified, including complexities related to licensing and limitations in available job information. Implications for nursing health human resources policy related to nurse retention in Canada are identified and discussed.
Job sharing as an employment alternative in group medical practice.
Vanek, E P; Vanek, J A
2001-01-01
Although physicians discuss quality-of-life and employment issues with their patients, they often fail to consider flexible scheduling and reduced employment options to lessen their own job stress. We examined one of these options by surveying two community-based, private practice groups with a combined 13-year experience with job sharing. We found that a majority of respondents rated job sharing as successful, and most wanted it to continue. Job sharers derived considerable personal benefit from the arrangement and had significantly more positive attitudes toward work than full-time physicians. Job sharing appeared to have little impact on practice parameters. Dependability, flexibility and willingness to cooperate were the most important attributes in choosing a job-sharing partner. Job sharing is an employment alternative worth exploring to retain physicians in medical group practice.

Flexible work in call centres: Working hours, work-life conflict & health.
Bohle, Philip; Willaby, Harold; Quinlan, Michael; McNamara, Maria
2011-01-01
Call-centre workers encounter major psychosocial pressures, including high work intensity and undesirable working hours. Little is known, however, about whether these pressures vary with employment status and how they affect work-life conflict and health. Questionnaire data were collected from 179 telephone operators in Sydney, Australia, of whom 124 (69.3%) were female and 54 (30.2%) were male. Ninety-three (52%) were permanent full-time workers, 37 (20.7%) were permanent part-time, and 49 (27.4%) were casual employees. Hypothesised structural relationships between employment status, working hours and work organisation, work-life conflict and health were tested using partial least squares modelling in PLS (Chin, 1998). The final model demonstrated satisfactory fit. It supported important elements of the hypothesised structure, although four of the proposed paths failed to reach significance and the fit was enhanced by adding a path. The final model indicated that casual workers reported more variable working hours which were relatively weakly associated with greater dissatisfaction with hours. The interaction of schedule control and variability of hours also predicted dissatisfaction with hours. Conversely, permanent workers reported greater work intensity, which was associated with both lower work schedule control and greater work-life conflict. Greater work-life conflict was associated with more fatigue and psychological symptoms. Labour market factors and the undesirability of longer hours in a stressful, high-intensity work environment appear to have contributed to the results.

This article presents a study on the evaluation of the workload imposed to workers of two sectors of a flexible packaging manufacturer that operates in three shifts. The workers are allocated in one of the shifts (morning, evening and night shifts) without evaluation of their chronotype and/or social needs. The Imprint sector has a more dynamic work, which is done only by man due to the effort demanded by handling loads. The work in the Cutting/Welding sector is static, done mainly by women. The results showed that the overall workload was the same in the Imprint and Cutting/Welding sectors, because physical effort for load handling is higher in the former but the latter involves high static load. The levels of urinary catecholamines and salivary cortisol were consistent with the workers biological clock showing that none of the workers changed his/her biological cycle to accommodate to the time of the shift schedule.

The work-family interface in the United States and Singapore: conflict across cultures.
Galovan, Adam M; Fackrell, Tamara; Buswell, Lydia; Jones, Blake L; Hill, E Jeffrey; Carroll, Sarah June
2010-10-01
This article examines the work-family interface in a cross-cultural comparison between two nationally representative samples from the United States (n = 1,860) and Singapore (n = 1,035) with emphasis on work-family conflict. Family-to-work conflict was negatively related to marital satisfaction in both Singapore and the United States, although the effect was stronger in the United States. Similarly, family-to-work conflict was positively related to job satisfaction in the United States but was negatively related in Singapore. As expected, schedule flexibility was negatively related to depression in the United States, but in Singapore the relationship was positive. These findings suggest that theoretical relationships in the work-family interface developed in the more culturally individualistic West may need to be adapted when studying populations in the more collectivist East.
The MICRO-BOSS scheduling system: Current status and future efforts
NASA Technical Reports Server (NTRS)
Sadeh, Norman M.
1993-01-01
In this paper, a micro-opportunistic approach to factory scheduling was described that closely monitors the evolution of bottlenecks during the construction of the schedule, and continuously redirects search towards the bottleneck that appears to be most critical. This approach differs from earlier opportunistic approaches, as it does not require scheduling large resource subproblems or large job subproblems before revising the current scheduling strategy. This micro-opportunistic approach was implemented in the context of the MICRO-BOSS factory scheduling system. A study comparing MICRO-BOSS against a macro-opportunistic scheduler suggests that the additional flexibility of the micro-opportunistic approach to scheduling generally yields important reductions in both tardiness and inventory.

A group of partners from an academic and industrial background are developing a flexible Cu(In,Ga)Se2 (CIGSe) thin film solar cell technology on a polyimide substrate that aims to be a future alternative to current rigid solar cell technologies for space applications. In particular on missions with high radiation volumes, the superior tolerance of chalcopyrite based thin film solar cell (TFSC) technologies with respect to electron and proton radiation, when compared to the established Si- or III-V based technologies, can be advantageous. Of all thin film technologies, those based on CIGSe have the highest potential to reach attractive photovoltaic conversion efficiencies and combine these with low weight in order to realize high power densities on solar cell and generator level. The use of a flexible substrate ensures a high packing density. A working demonstrator is scheduled for flight this year.

NDCX-II is a newly completed accelerator facility at LBNL, built to study ion-heated warm dense matter, as well as aspects of ion-driven targets and intense-beam dynamics for inertial-fusion energy. The baseline design calls for using 12 induction cells to accelerate 30-50 nC of Li+ ions to 1.2 MeV. During commissioning, though, we plan to extend the source lifetime by extracting less total charge. Over time, we expect that NDCX-II will be upgraded to substantially higher energies, necessitating the use of heavier ions to keep a suitable deposition range in targets. For operational flexibility, the option of using a helium plasma source is also being investigated. Each of these options requires development of an alternate acceleration schedule. The schedules here are worked out with a fast-running 1-D particle-in-cell code ASP.
Wind Power Ramping Product for Increasing Power System Flexibility
DOE Office of Scientific and Technical Information (OSTI.GOV)
Cui, Mingjian; Zhang, Jie; Wu, Hongyu
With increasing penetrations of wind power, system operators are concerned about a potential lack of system flexibility and ramping capacity in real-time dispatch stages. In this paper, a modified dispatch formulation is proposed considering the wind power ramping product (WPRP). A swinging door algorithm (SDA) and dynamic programming are combined and used to detect WPRPs in the next scheduling periods. The detected WPRPs are included in the unit commitment (UC) formulation considering ramping capacity limits, active power limits, and flexible ramping requirements. The modified formulation is solved by mixed integer linear programming. Numerical simulations on a modified PJM 5-bus Systemmore » show the effectiveness of the model considering WPRP, which not only reduces the production cost but also does not affect the generation schedules of thermal units.« less

Attrition rates in emergency medicine have been reported as high as 25% in 10 years. The number of women entering emergency medicine has been increasing, as has the number of female medical school graduates. No studies have identified factors that increase female emergency physician career satisfaction. We assess career satisfaction in women emergency physicians in the American College of Emergency Physicians (ACEP) and identify factors associated with career satisfaction. The survey questionnaire was developed by querying 3 groups: (1) ACEP women in the American Association of Women Emergency Physicians, the (2) Society for Academic Emergency Medicine Mentoring Women Interest Group, and (3) nonaffiliated female emergency physicians. Their responses were categorized into 6 main areas: schedule, relationships with colleagues, administrative support and mentoring, patient/work-related issues, career advancement opportunities, and financial. The study cohort for the survey included all female members of ACEP with a known e-mail address. All contact with survey recipients was exclusively through the e-mail that contained a uniform resource locator link to the survey itself. Two thousand five hundred two ACEP female members were sent the uniform resource locator link. The Web survey was accessed a total of 1,851 times, with a total of 1,380 surveys completed, an overall response rate of 56%. Most women were satisfied with their career as an emergency physician, 492 (35.5%) very satisfied, 610 (44.0%) satisfied, 154 (11.1%) neutral, 99 (7.1%) not satisfied, and 31 (2.3%) very unsatisfied. Significant factors for career satisfaction included amount of recognition at work, career advancement, schedule flexibility, and the fairness of financial compensation. Workplace factors associated with high satisfaction included academic practice setting and sex-equal opportunity for advancement and sex-equal financial compensation. Most of the ACEP female physicians surveyed were satisfied with their career choice of emergency medicine. Opportunities for career advancement, fairness in financial compensation, and schedule flexibility were key factors in career satisfaction among female emergency physicians.

A laboratory is an essential equipment for engineering students to do a useful practical work. Therefore, universities should provide an adequate facility for practical work. On the other hand, industrial automation laboratory would offer students beneficial experience by using various educational PLC kits. This paper describes the development of Web-based Programmable Logic Controller (PLC) remote laboratory called RLab. It provides an environment for learners to study PLC application to control the level of the non-interacting tank. The RLab architecture is based on a Moodle and Remote Desktop, which also manages the booking system of the schedule of practical work in the laboratory. The RLab equipped by USB cameras providing a real-time view of PLC environment. To provide a secured system, the RLab combines Moodle and Remote Desktop application for the authentication system and management of remote users. Moodle will send PartnerID and password to connect to TeamViewer. It has been examined that the laboratory requirement, time and flexibility restrictions constitute a significant obstacle facing traditional students desiring to finish the course. A remote access laboratory can be eliminating time and flexibility restrictions. The preliminary study of RLab usability proved that such system is adequate to give the learners a distance practical work environment.

Compensation is a key variable in recruitment and retention of registered nurses. A 6-month trial of an exempt/salaried wage program for registered nurses, based on normative change theory, was implemented in the adult critical care division of a 491-bed community hospital. A total of 58 registered nurses participated in the trial. At the end of 6 months on salary, 94% (53) of the nurses voted to remain salaried. The staff perceived that the new wage program increased flexibility in work schedules and promoted teamwork and professional autonomy.
A salaried compensation model for postanesthesia nurses.

Health care organizations involved in innovative and creative work redesign projects may find traditional pay structures inadequate to meet the needs of the changing environment. The idea of salaried compensation for registered nurses is not unprecedented. However, few salaried compensation models for nurses are described in the literature. This article presents a model that we believe will be of particular interest to nurses in PACUs, because its design allows for adequate call coverage plus flexibility in scheduling. In addition, this compensation model eliminates incidental overtime, thus allowing for a more predictable salary budget.

The VLBI Global Observing System (VGOS) has been designed to take advantage of advances in data recording speeds and storage capacity, allowing for smaller and faster antennas, wider bandwidths, and shorter observation durations. Here, schedules for a ``realistic" VGOS network, frequency sequences, and expanded source lists are presented using a new source-based scheduling algorithm. The VGOS aim for continuous observations presents new operational challenges. As the source-based strategy is independent of the observing network, there are operational advantages which allow for more flexible scheduling of continuous VLBI observations. Using VieVS, simulations of several schedules are presented and compared with previous VGOS studies.

Stochastic disturbances occurring in real-world operations could have a significant influence on the planned routing and scheduling results of cash transportation vehicles. In this study, a time-space network flow technique is utilized to construct a cash transportation vehicle routing and scheduling model incorporating stochastic travel times. In addition, to help security carriers to formulate more flexible routes and schedules, a concept of the similarity of time and space for vehicle routing and scheduling is incorporated into the model. The test results show that the model could be useful for security carriers in actual practice.

This study examines work-family role conflict and the factors predicting it, with a sample of 173 professional women in engineering and information technology (IT) firms, including 2 hospitals-1 public and 1 private. Our findings show no significant difference in the level of work-family role conflict encountered by women across medicine, engineering, and IT, whereas hours of work, family responsibilities, job demand, and work role overload were significantly correlated with work-family role conflict. Multiple linear regression analysis indicates that only work role overload, family responsibilities, and hours of work significantly predicted 45.9% of work-family role conflict. This implies that working women are burdened by work demands, which invariably affects the work-family role conflict they experience and leads to deterioration of their occupational health. It is suggested that employers should create a flexible work schedule and establish family-friendly policies in the workplace to promote a healthy work-life balance for women in science careers.
Correlates to long-term-care nurse turnover: survey results from the state of West Virginia.
Hodgin, Robert F; Chandra, Ashish; Weaver, Crystal
2010-01-01
The authors sought statistical correlates to long-term-care nurse turnover using surveys from 253 practicing nurses across 54 of 55 counties in West Virginia. A chi-square test for homogeneity showed significant relationships between select demographic variables and job-related dimensions categorized either as benefits (pay, schedule flexibility and growth opportunity, travel time to work, patient behavior, facility conditions, supervisor relations) or job-related dimensions categorized as costs (travel time to work, patient behavior, facility conditions, supervisor relations, and family needs). Five demographic characteristics: gender, education level, job title, county in West Virginia region, and facility size bore no relationship to any job-related dimension listed.

There is this tendency to think there s only one way to get from A to B. It turns out there are an infinite number of ways to get from point A to point B. What may work on one pro.ject may not work very well on another project for a variety of reasons. The lesson I've learned is that while it s good to have a road map, you have to realize the map is good for today, but it may change tomorrow, and it may change again the nest day. Use thc schedule as a too1 and he flexible, if you can. Cultivate a great team, take advantage of their experience, and pray for good luck.

Aim This article describes the development and testing of an Excel-based scheduling solution for the flexible allocation and reallocation of nurses to cover sudden, unplanned absences among permanent nursing staff. Method A quasi-experimental, one group, pre- and post-test study design was used ( Box 1 ) with total sampling. Participants (n=17) were selected purposefully by including all ward managers (n=8) and assistant ward managers (n=9) from one university hospital department. The number of sudden absences among the nursing staff was identified during two 4-week data collection periods (pre- and post-test). Results During the use of the paper-based scheduling system, 121 absences were identified; during the use of the Excel-based system, 106 were identified. The main reasons for the use of flexible 'floating' nurses were sick leave (n=66) and workload (n=31). Other reasons (n=29) included patient transfer to another hospital, scheduling errors and the start or end of employment. Conclusion The Excel-based scheduling solution offered better support in obtaining substitute labour inside the organisation, with smaller employment costs. It also reduced the number of tasks ward managers had to carry out during the process of reallocating staff.

Resource Managers like Apache YARN have emerged as a critical layer in the cloud computing system stack, but the developer abstractions for leasing cluster resources and instantiating application logic are very low-level. This flexibility comes at a high cost in terms of developer effort, as each application must repeatedly tackle the same challenges (e.g., fault-tolerance, task scheduling and coordination) and re-implement common mechanisms (e.g., caching, bulk-data transfers). This paper presents REEF, a development framework that provides a control-plane for scheduling and coordinating task-level (data-plane) work on cluster resources obtained from a Resource Manager. REEF provides mechanisms that facilitate resource re-use for data caching, and state management abstractions that greatly ease the development of elastic data processing work-flows on cloud platforms that support a Resource Manager service. REEF is being used to develop several commercial offerings such as the Azure Stream Analytics service. Furthermore, we demonstrate REEF development of a distributed shell application, a machine learning algorithm, and a port of the CORFU [4] system. REEF is also currently an Apache Incubator project that has attracted contributors from several instititutions.1 PMID:26819493
Operations mission planner beyond the baseline

The scheduling of Space Station Freedom must satisfy four major requirements. It must ensure efficient housekeeping operations, maximize the collection of science, respond to changes in tasking and available resources, and accommodate the above changes in a manner that minimizes disruption of the ongoing operations of the station. While meeting these requirements the scheduler must cope with the complexity, scope, and flexibility of SSF operations. This requires the scheduler to deal with an astronomical number of possible schedules. The Operations Mission Planner (OMP) is centered around minimally disruptive replanning and the use of heuristics limit search in scheduling. OMP has already shown several artificial intelligence based scheduling techniques such as Interleaved Iterative Refinement and Bottleneck Identification using Process Chronologies.

There is a demand for ways to enhance cognitive flexibility, as it can be a limiting factor for performance in daily life. Video game training has been linked to advantages in cognitive functioning, raising the question if training with video games can promote cognitive flexibility. In the current study, we investigated if game-based computerized cognitive training (GCCT) could enhance cognitive flexibility in a healthy young adult sample (N = 72), as measured by task-switch performance. Three GCCT schedules were contrasted, which targeted: (1) cognitive flexibility and task switching, (2) attention and working memory, or (3) an active control involving basic math games, in twenty 45-min sessions across 4-6 weeks. Performance on an alternating-runs task-switch paradigm during pretest and posttest sessions indicated greater overall reaction time improvements after both flexibility and attention training as compared to control, although not related to local switch cost. Flexibility training enhanced performance in the presence of distractor-related interference. In contrast, attention training was beneficial when low task difficulty undermined sustained selective attention. Furthermore, flexibility training improved response selection as indicated by a larger N2 amplitude after training as compared to control, and more efficient conflict monitoring as indicated by reduced Nc/CRN and larger Pe amplitude after training. These results provide tentative support for the efficacy of GCCT and suggest that an ideal training might include both task switching and attention components, with maximal task diversity both within and between training games.

Shiftwork is a major job demand for nurses and has been related to various negative consequences. Research suggests that personal and job resources moderate the impact of work schedules on stress, health and well-being. This longitudinal study examined whether the interactions of personal and job resources with work schedule demands predicted work engagement and emotional exhaustion in nursing. This longitudinal study included two waves of data collection with a one year follow-up using self-report questionnaires among 247 nurses working shifts or irregular working hours in residential care for the elderly in the Netherlands. Moderated structural equation modelling was conducted to examine the interactions between personal and job resources and work schedule demands. Two work schedule demands were assessed: type of work schedule (demanding vs. less demanding) and average weekly working hours. Two personal resources, active coping and healthy lifestyle, and two job resources, work schedule control and the work schedule fit with nurses' private life, were assessed. Results showed that the work schedule fit with nurses' private life buffered the relationship between work schedule demands and emotional exhaustion one year later. Furthermore, the work schedule fit with nurses' private life increased work engagement one year later when work schedule demands were high. Work schedule control strengthened the positive relationship between work schedule demands and emotional exhaustion one year later. The personal resources, active coping and healthy lifestyle were no moderators in this model. Nurses suffer less from decreasing work engagement and emotional exhaustion due to work schedule demands when their work schedules fit with their private lives. Work schedule control did not buffer, but strengthened the positive relationship between weekly working hours and emotional exhaustion one year later. Job resources appeared to be more important for nurses' well-being than personal resources. These findings highlight the importance of the fit of a work schedule with nurse's private life, if the work schedule is demanding. Copyright © 2016. Published by Elsevier Ltd.
A Two-Stage Probabilistic Approach to Manage Personal Worklist in Workflow Management Systems
NASA Astrophysics Data System (ADS)
Han, Rui; Liu, Yingbo; Wen, Lijie; Wang, Jianmin
The application of workflow scheduling in managing individual actor's personal worklist is one area that can bring great improvement to business process. However, current deterministic work cannot adapt to the dynamics and uncertainties in the management of personal worklist. For such an issue, this paper proposes a two-stage probabilistic approach which aims at assisting actors to flexibly manage their personal worklists. To be specific, the approach analyzes every activity instance's continuous probability of satisfying deadline at the first stage. Based on this stochastic analysis result, at the second stage, an innovative scheduling strategy is proposed to minimize the overall deadline violation cost for an actor's personal worklist. Simultaneously, the strategy recommends the actor a feasible worklist of activity instances which meet the required bottom line of successful execution. The effectiveness of our approach is evaluated in a real-world workflow management system and with large scale simulation experiments.
Truck driver fatigue risk assessment and management: a multinational survey.
Adams-Guppy, Julie; Guppy, Andrew
2003-06-20
As part of an organizational review of safety, interviews and questionnaire surveys were performed on over 700 commercial goods drivers and their managers within a series of related companies operating across 17 countries. The results examine the reported incidence of fatigue-related problems in drivers and their associations with near miss and accident experience as well as work and organizational factors. Experience of fatigue problems while driving was linked to time of day and rotation of shifts, though most associations were small. There were significant associations found between fatigue experiences and driver and management systems of break taking and route scheduling. The quantitative combined with qualitative information suggested that, where feasible, more flexible approaches to managing the scheduling and sequencing of deliveries assisted drivers in managing their own fatigue problems through appropriate break-taking. The results are interpreted within the overarching principles of risk assessment and risk control.

Reutilization of software is a difficult goal to achieve particularly in complex environments that require advanced software systems. The Request-Oriented Scheduling Engine (ROSE) was developed to create a reusable scheduling system for the diverse scheduling needs of the National Aeronautics and Space Administration (NASA). ROSE is a data-driven scheduler that accepts inputs such as user activities, available resources, timing contraints, and user-defined events, and then produces a conflict-free schedule. To support reutilization, ROSE is designed to be flexible, extensible, and portable. With these design features, applying ROSE to a new scheduling application does not require changing the core scheduling engine, even if the new application requires significantly larger or smaller data sets, customized scheduling algorithms, or software portability. This paper includes a ROSE scheduling system description emphasizing its general-purpose features, reutilization techniques, and tasks for which ROSE reuse provided a low-risk solution with significant cost savings and reduced software development time.

Problems that appear in a company that produces refined sugar, the production floor has not reached the level of critical machine availability because it often suffered damage (breakdown). This results in a sudden loss of production time and production opportunities. This problem can be solved by Reliability Engineering method where the statistical approach to historical damage data is performed to see the pattern of the distribution. The method can provide a value of reliability, rate of damage, and availability level, of an machine during the maintenance time interval schedule. The result of distribution test to time inter-damage data (MTTF) flexible hose component is lognormal distribution while component of teflon cone lifthing is weibull distribution. While from distribution test to mean time of improvement (MTTR) flexible hose component is exponential distribution while component of teflon cone lifthing is weibull distribution. The actual results of the flexible hose component on the replacement schedule per 720 hours obtained reliability of 0.2451 and availability 0.9960. While on the critical components of teflon cone lifthing actual on the replacement schedule per 1944 hours obtained reliability of 0.4083 and availability 0.9927.

In the case of rapid development of wind power and heavy wind curtailment, the study of wind power accommodation of combined heat and power system has become the focus of attention. A two-stage scheduling model contains of wind power, thermal energy storage, CHP unit and flexible load were constructed. This model with the objective function of minimizing wind curtailment and the operation cost of units while taking into account of the total coal consumption of units, constraint of thermal energy storage and electricity-heat characteristic of CHP. This paper uses MICA to solve the problem of too many constraints and make the solution more feasible. A numerical example showed that the two stage decision scheduling model can consume more wind power, and it could provide a reference for combined heat and power system short-term operation
Understanding London's Water Supply Tradeoffs When Scheduling Interventions Under Deep Uncertainty

Water supply planning in many major world cities faces several challenges associated with but not limited to climate change, population growth and insufficient land availability for infrastructure development. Long-term plans to maintain supply-demand balance and ecosystem services require careful consideration of uncertainties associated with future conditions. The current approach for London's water supply planning utilizes least cost optimization of future intervention schedules with limited uncertainty consideration. Recently, the focus of the long-term plans has shifted from solely least cost performance to robustness and resilience of the system. Identifying robust scheduling of interventions requires optimizing over a statistically representative sample of stochastic inputs which may be computationally difficult to achieve. In this study we optimize schedules using an ensemble of plausible scenarios and assess how manipulating that ensemble influences the different Pareto-approximate intervention schedules. We investigate how a major stress event's location in time as well as the optimization problem formulation influence the Pareto-approximate schedules. A bootstrapping method that respects the non-stationary trend of climate change scenarios and ensures the even distribution of the major stress event in the scenario ensemble is proposed. Different bootstrapped hydrological scenario ensembles are assessed using many-objective scenario optimization of London's future water supply and demand intervention scheduling. However, such a "fixed" scheduling of interventions approach does not aim to embed flexibility or adapt effectively as the future unfolds. Alternatively, making decisions based on the observations of occurred conditions could help planners who prefer adaptive planning. We will show how rules to guide the implementation of interventions based on observations may result in more flexible strategies.
EEOC claims employer refused reasonable accommodation. Equal Employment Opportunity Commission.
1995-06-30
The Equal Employment Opportunity Commission (EEOC) has sued Spectacor, one of the largest stadium-management companies, on behalf of employee [name removed]. [Name removed], who claimed his employer refused to grant him flexible work hours to accommodate his AIDS diagnosis. [Name removed] had submitted a note from one of his doctors stating that [name removed] had AIDS and was taking an experimental medicine. The doctors requested some added flexibility in working hours to enable [name removed] to prepare special meals and take showers to reduce the discomfort of the experimental medicines he was taking. Spectacor, instead of granting the request, informed [name removed] that his job was in jeopardy and that he would be discharged because of absenteeism and declining productivity. The suit alleges Spectacor violated the Americans with Disabilities Act (ADA) by refusing to grant [name removed] a reasonable accommodation for his disability and that the employer had breached its obligation to keep confidential his medical information. Spectacor denied that its refusal to accommodate [name removed]'s scheduling requests constituted a violation of the ADA.
Perspectives of being spouse, parent, and surgeon.

Achieving a balance between one's career and personal life is a never-ending challenge. As a surgeon, add-on cases and double-booked clinics can lead to long hours at work and make availability for family time unpredictable. It may seem like the threat of interruption because of patient needs always loom. Disruptions to family time extend beyond the long hours spent in surgery and clinics. Inattentiveness at home because of the technology tethers that keep one available for constant questions and patient care issues can also distract from time spent with family. Although the practice of an orthopaedic trauma surgeon can involve unpredictable schedules and patient care issues, there are means of mitigating the chaos that can envelop one's personal life as a result of a chosen career track. Clear priorities and expectations in both personal and professional arenas can improve the work-life balance. Flexible jobs that allow for more time with family do exist. Negotiating for this flexibility and self-assurance in holding fast to personal ideals are important in achieving a successful balance.

This study used the discrete-events computer simulation methodology to model a large hospital surgical centre (SC), in order to analyse the impact of increases in the number of post-anaesthetic beds (PABs), of changes in surgical room scheduling strategies and of increases in surgery numbers. The used inputs were: number of surgeries per day, type of surgical room scheduling, anaesthesia and surgery duration, surgical teams' specialty and number of PABs, and the main outputs were: number of surgeries per day, surgical rooms' use rate and blocking rate, surgical teams' use rate, patients' blocking rate, surgery delays (minutes) and the occurrence of postponed surgeries. Two basic strategies were implemented: in the first strategy, the number of PABs was increased under two assumptions: (a) following the scheduling plan actually used by the hospital (the 'rigid' scheduling - surgical rooms were previously assigned and assignments could not be changed) and (b) following a 'flexible' scheduling (surgical rooms, when available, could be freely used by any surgical team). In the second, the same analysis was performed, increasing the number of patients (up to the system 'feasible maximum') but fixing the number of PABs, in order to evaluate the impact of the number of patients over surgery delays. It was observed that the introduction of a flexible scheduling/increase in PABs would lead to a significant improvement in the SC productivity.

To evaluate the impact of residency work hour limitations on pediatrics residency programs in New York State, and to learn lessons that can be used nationally with the implementation of the Accreditation Council of Graduate Medical Education's similar rules. A three-page questionnaire was mailed to all pediatrics residency program directors in New York. The questionnaire assessed methods used to accommodate the work hour limitations and perceptions of the limitations' effects. Twenty-one program directors responded (68%). Only large programs used night floats and night teams to meet work hour requirements. Programs of all sizes and in all settings used cross coverage and sent residents home immediately post call. About half of the programs hired additional nonresident staff, usually nurse practitioners, physician assistants, and/or attendings. The most frequently reported effects were decreases in the amount of time residents spent in inpatient settings, patient continuity in inpatient settings, flexibility of residents' scheduling, and increased logistical work needed to maintain continuity clinic. A summary of advice to other program directors was "be creative" and "be flexible." New York's pediatrics residency programs used a variety of mechanisms to meet work hour restrictions. Smaller programs had fewer methods available to them to meet such restrictions. Although the logistical work needed to maintain continuity clinic increased greatly, continuity and outpatient settings themselves were not greatly affected by work hour limitations. Inpatient settings were more affected and experienced much more in the way of change.

The Peregrine sounding rocket is an in-house NASA design that provides approximately 15 percent better performance than the motor it replaces. The design utilizes common materials and well-characterized architecture to reduce flight issues encountered with the current motors. It engages NASA design, analysts, test engineers and technicians, ballisticians, and systems engineers. The in-house work and collaboration within the government provides flexibility to efficiently accommodate design and program changes as the design matures and enhances the ability to meet schedule milestones. It provides a valuable tool to compare industry costs, develop contracts, and it develops foundational knowledge for the next generation of NASA engineers.
Naps promote flexible memory retrieval in 12-month-old infants.

2016-11-01
Flexibility in applying existing knowledge to similar cues is a corner stone of memory development in infants. Here, we examine the effect of sleep on the flexibility of memory retrieval using a deferred imitation paradigm. Forty-eight 12-month-old infants were randomly assigned to either a nap or a no-nap demonstration condition (scheduled around their natural daytime sleep schedule) or to a baseline control condition. In the demonstration conditions, infants watched an experimenter perform three target actions on a hand puppet. Immediately afterwards, infants were allowed to practice the target actions three times. In a test session 4-hr later, infants were given the opportunity to reproduce the actions with a novel hand puppet differing in color from the puppet used during the demonstration session. Only infants in the nap-condition performed significantly more target actions than infants in the baseline control condition. Furthermore, they were faster to carry out the first target action than infants in the no-nap condition. We conclude that sleep had a facilitative effect on infants' flexibility of memory retrieval. © 2016 Wiley Periodicals, Inc.
The effect of alternative work arrangements on women's well-being: a demand-control model.
Kelloway, E K; Gottlieb, B H
1998-01-01
The growth of women's participation in the labor force and evidence of the conflict they experience between job and family demands have spurred many employers to introduce alternative work arrangements such as flextime, job sharing, and telecommuting. Drawing on data gained from a sample of women (N = 998) in two large Canadian organizations, this study evaluates two mediational models of the impact of alternative work arrangements on women's stress and family role competence. Specifically, it tests and finds support for the hypotheses that (a) work arrangements involving scheduling flexibility (telecommuting and flextime) promote these aspects of women's well-being by increasing their perceived control over their time, and (b) arrangements involving reduced hours of employment (part-time employment and job sharing) promote well-being by reducing perceived job overload. Discussion of these findings centers on their implications for employed women, their employers, and future research.

Planning and scheduling of NASA Space Shuttle missions is a complex, labor-intensive process requiring the expertise of experienced mission planners. We have developed a planning and scheduling system using combinations of artificial intelligence knowledge representations and planning techniques to capture mission planning knowledge and automate the multi-mission planning process. Our integrated object oriented and rule-based approach reduces planning time by orders of magnitude and provides planners with the flexibility to easily modify planning knowledge and constraints without requiring programming expertise.
Female Physicians and the Work-Family Conflict.
Treister-Goltzman, Yulia; Peleg, Roni
2016-05-01
There has been a dramatic increase in the number of female physicians in all fields and specializations of medicine, but this increase has not resulted in a redistribution of domestic tasks and responsibilities. Reviewing the literature of the last two decades (April 1994 to April 2014) on how female physicians cope with the challenge of balancing their family and professional lives for the duration of their professional careers revealed that they suffer from the work-family conflict more than other professionals and that it has a more negative effect on women than on men. Women physicians consider work-family balance significantly when making career choices. These considerations affect their career success, their productivity as faculty members, their marital life, and parenthood. Having a supportive spouse at home and a facilitating mentor at work are important for a positive work-family balance among female physicians. Special career-supporting measures, such as flexible work schedules and expanded support for childcare over the course of work and when taking part in academic activities, are critical for female physicians.
Space network scheduling benchmark: A proof-of-concept process for technology transfer

Moe, Karen; Happell, Nadine; Hayden, B. J.; Barclay, Cathy
1993-01-01
This paper describes a detailed proof-of-concept activity to evaluate flexible scheduling technology as implemented in the Request Oriented Scheduling Engine (ROSE) and applied to Space Network (SN) scheduling. The criteria developed for an operational evaluation of a reusable scheduling system is addressed including a methodology to prove that the proposed system performs at least as well as the current system in function and performance. The improvement of the new technology must be demonstrated and evaluated against the cost of making changes. Finally, there is a need to show significant improvement in SN operational procedures. Successful completion of a proof-of-concept would eventually lead to an operational concept and implementation transition plan, which is outside the scope of this paper. However, a high-fidelity benchmark using actual SN scheduling requests has been designed to test the ROSE scheduling tool. The benchmark evaluation methodology, scheduling data, and preliminary results are described.
Spike: AI scheduling for Hubble Space Telescope after 18 months of orbital operations

Johnston, Mark D.
1992-01-01
This paper is a progress report on the Spike scheduling system, developed by the Space Telescope Science Institute for long-term scheduling of Hubble Space Telescope (HST) observations. Spike is an activity-based scheduler which exploits artificial intelligence (AI) techniques for constraint representation and for scheduling search. The system has been in operational use since shortly after HST launch in April 1990. Spike was adopted for several other satellite scheduling problems; of particular interest was the demonstration that the Spike framework is sufficiently flexible to handle both long-term and short-term scheduling, on timescales of years down to minutes or less. We describe the recent progress made in scheduling search techniques, the lessons learned from early HST operations, and the application of Spike to other problem domains. We also describe plans for the future evolution of the system.
Maximally Expressive Task Modeling
NASA Technical Reports Server (NTRS)
Japp, John; Davis, Elizabeth; Maxwell, Theresa G. (Technical Monitor)
2002-01-01
Planning and scheduling systems organize "tasks" into a timeline or schedule. The tasks are defined within the scheduling system in logical containers called models. The dictionary might define a model of this type as "a system of things and relations satisfying a set of rules that, when applied to the things and relations, produce certainty about the tasks that are being modeled." One challenging domain for a planning and scheduling system is the operation of on-board experiment activities for the Space Station. The equipment used in these experiments is some of the most complex hardware ever developed by mankind, the information sought by these experiments is at the cutting edge of scientific endeavor, and the procedures for executing the experiments are intricate and exacting. Scheduling is made more difficult by a scarcity of space station resources. The models to be fed into the scheduler must describe both the complexity of the experiments and procedures (to ensure a valid schedule) and the flexibilities of the procedures and the equipment (to effectively utilize available resources). Clearly, scheduling space station experiment operations calls for a "maximally expressive" modeling schema. Modeling even the simplest of activities cannot be automated; no sensor can be attached to a piece of equipment that can discern how to use that piece of equipment; no camera can quantify how to operate a piece of equipment. Modeling is a human enterprise-both an art and a science. The modeling schema should allow the models to flow from the keyboard of the user as easily as works of literature flowed from the pen of Shakespeare. The Ground Systems Department at the Marshall Space Flight Center has embarked on an effort to develop a new scheduling engine that is highlighted by a maximally expressive modeling schema. This schema, presented in this paper, is a synergy of technological advances and domain-specific innovations.
Integrated resource scheduling in a distributed scheduling environment
NASA Technical Reports Server (NTRS)
Zoch, David; Hall, Gardiner
1988-01-01
The Space Station era presents a highly-complex multi-mission planning and scheduling environment exercised over a highly distributed system. In order to automate the scheduling process, customers require a mechanism for communicating their scheduling requirements to NASA. A request language that a remotely-located customer can use to specify his scheduling requirements to a NASA scheduler, thus automating the customer-scheduler interface, is described. This notation, Flexible Envelope-Request Notation (FERN), allows the user to completely specify his scheduling requirements such as resource usage, temporal constraints, and scheduling preferences and options. The FERN also contains mechanisms for representing schedule and resource availability information, which are used in the inter-scheduler inconsistency resolution process. Additionally, a scheduler is described that can accept these requests, process them, generate schedules, and return schedule and resource availability information to the requester. The Request-Oriented Scheduling Engine (ROSE) was designed to function either as an independent scheduler or as a scheduling element in a network of schedulers. When used in a network of schedulers, each ROSE communicates schedule and resource usage information to other schedulers via the FERN notation, enabling inconsistencies to be resolved between schedulers. Individual ROSE schedules are created by viewing the problem as a constraint satisfaction problem with a heuristically guided search strategy.
Kronos Observatory Operations Challenges in a Lean Environment

Kronos is a multiwavelength observatory designed to map the accretion disks and environments of supermassive black holes in various environments using the natural intrinsic variability of the accretion-driven sources. Kronos is envisaged as a Medium Explorer mission to NASA Office of Space Science under the Structure and Evolution of the Universe theme. We will achieve the Kronos science objectives by developing cost-effective techniques for obtaining and assimilating data from the research spacecraft and its subsequent work on the ground. The science operations assumptions for the mission are: (1 Need for flexible scheduling due to the variable nature of targets, (2) Large data volumes but minimal ground station contact, (3) Very small staff for operations. Our first assumption implies that we will have to consider an effective strategy to dynamically reprioritize the observing schedule to maximize science data acquisition. The flexibility we seek greatly increases the science return of the mission, because variability events can be properly captured. Our second assumption implies that we will have to develop some basic on-board analysis strategies to determine which data get downloaded. The small size of the operations staff implies that we need to "automate" as many routine processes of science operations as possible. In this paper we will discuss the various solutions that we are considering to optimize our operations and maximize science returns on the observatory.

Background: The OSCE (objective structured clinical examination) is composed of oral and practical examination in order to examine students’ abilities to imply clinical examination techniques and to interact with patients. The examiners for this procedure can be either lecturers or peers. The aim of this work is to evaluate the peer-assisted teaching student tutors as examiners in an orthopedic surgery OSCE station. Methods: We analyzed the OSCE data from 2013 to 2015. During this period over 300 medical students were examined each year. An evaluation was conducted at an orthopedic station and examined by peer students to assess the advantages and disadvantages of peer-assisted teaching student tutors as examiners. Results: We have noticed that student peers are more flexible regarding their schedule and they have been well trained for OSCE. Concerning the economic aspects, student peers are clearly of major economic advantage. Disadvantages were not reported in our study probably because peers were well trained and the checklists are monitored regularly. Conclusion: Student peers in OSCE are of major advantage due to their flexible time schedule and relatively low costs. They must be well trained and the checklists are to be monitored regularly. Our study shows that peer tutor examiners conducted the examination as competent as lecture examiners. However, legal restrictions on the employment of students should be considered. PMID:27500078
The MICRO-BOSS scheduling system: Current status and future efforts
NASA Technical Reports Server (NTRS)
Sadeh, Norman M.
1992-01-01
In this paper, a micro-opportunistic approach to factory scheduling was described that closely monitors the evolution of bottlenecks during the construction of the schedule and continuously redirects search towards the bottleneck that appears to be most critical. This approach differs from earlier opportunistic approaches, as it does not require scheduling large resource subproblems or large job subproblems before revising the current scheduling strategy. This micro-opportunistic approach was implemented in the context of the MICRO-BOSS factory scheduling system. A study comparing MICRO-BOSS against a macro-opportunistic scheduler suggests that the additional flexibility of the micro-opportunistic approach to scheduling generally yields important reductions in both tardiness and inventory. Current research efforts include: adaptation of MICRO-BOSS to deal with sequence-dependent setups and development of micro-opportunistic reactive scheduling techniques that will enable the system to patch the schedule in the presence of contingencies such as machine breakdowns, raw materials arriving late, job cancellations, etc.

The dispatch method which track the trend of load demand by arranging the generation scheme of controllable hydro or thermal units faces great difficulties and challenges. With the increase of renewable energy sources such as wind power and photovoltaic power introduced to grid, system has to arrange much more spinning reserve units to compensate the unbalanced power. How to exploit the peak-shaving potential of flexible load which can be shifted with time or storage energy has become many scholars’ research direction. However, the modelling of different kinds of load and control strategy is considerably difficult, this paper choose the Air Conditioner with compressor which can storage energy in fact to study. The equivalent thermal parameters of Air Conditioner has been established. And with the use of “loop control” strategies, we can predict the regulated power of Air Conditioner. Then we established the Gen-Load optimal scheduling model including flexible load based on traditional optimal scheduling model. At last, an improved IEEE-30 case is used to verify. The result of simulation shows that flexible load can fast-track renewable power changes. More than that, with flexible load and reasonable incentive method to consumers, the operating cost of the system can be greatly cut down.

Nowadays, fabrication systems and methods are being modified; new processing technologies come up, flow sheets develop a minimum number of phases, the flexibility of the technologies grows up, new methods and instruments of monitoring and leading the processing operations also come up. The technological course (route, entry, scheme, guiding) referring to the series of the operation, putting and execution phases of a mark in order to obtain the final product from the blank is represented by a sequence of activities realized by a logic manner, on a well determined schedule, with a determined budget and resources. Also, a project can be defined as a series of specific activities, methodical structured which they aim to finish a specific objective, within a fixed schedule and budget. Within the homogeneity between the project and the technological course, this research is presenting the defining of the technological course of mechanical chip removing process using Microsoft Project. Under these circumstances, this research highlights the advantages of this method: the celerity using of other technological alternatives in order to pick the optimal process, the job scheduling being constrained by any kinds, the standardization of some processing technological operations.
Motherhood during residency training: challenges and strategies.

To determine what factors enable or impede women in a Canadian family medicine residency program from combining motherhood with residency training. To determine how policies can support these women, given that in recent decades the number of female family medicine residents has increased. Qualitative study using in-person interviews. McMaster University Family Medicine Residency Program. Twenty-one of 27 family medicine residents taking maternity leave between 1994 and 1999. Semistructured interviews. The research team reviewed transcripts of audiotaped interviews for emerging themes; consensus was reached on content and meaning. NVIVO software was used for data analysis. Long hours, unpredictable work demands, guilt because absences from work increase workload for colleagues, and residents' high expectations of themselves cause pregnant residents severe stress. This stress continues upon return to work; finding adequate child care is an added stress. Residents report receiving less support from colleagues and supervisors upon return to work; they associate this with no longer being visibly pregnant. Physically demanding training rotations put additional strain on pregnant residents and those newly returned to work. Flexibility in scheduling rotations can help accommodate needs at home. Providing breaks, privacy, and refrigerators at work can help maintain breastfeeding. Allowing residents to remain involved in academic and clinical work during maternity leave helps maintain clinical skills, build new knowledge, and promote peer support. Pregnancy during residency training is common and becoming more common. Training programs can successfully enhance the experience of motherhood during residency by providing flexibility at work to facilitate a healthy balance among the competing demands of family, work, and student life.

Flexible manufacturing system (FMS) enhances the firm's flexibility and responsiveness to the ever-changing customer demand by providing a fast product diversification capability. Performance of an FMS is highly dependent upon the accuracy of scheduling policy for the components of the system, such as automated guided vehicles (AGVs). An AGV as a mobile robot provides remarkable industrial capabilities for material and goods transportation within a manufacturing facility or a warehouse. Allocating AGVs to tasks, while considering the cost and time of operations, defines the AGV scheduling process. Multi-objective scheduling of AGVs, unlike single objective practices, is a complex and combinatorial process. In the main draw of the research, a mathematical model was developed and integrated with evolutionary algorithms (genetic algorithm (GA), particle swarm optimization (PSO), and hybrid GA-PSO) to optimize the task scheduling of AGVs with the objectives of minimizing makespan and number of AGVs while considering the AGVs' battery charge. Assessment of the numerical examples' scheduling before and after the optimization proved the applicability of all the three algorithms in decreasing the makespan and AGV numbers. The hybrid GA-PSO produced the optimum result and outperformed the other two algorithms, in which the mean of AGVs operation efficiency was found to be 69.4, 74, and 79.8 percent in PSO, GA, and hybrid GA-PSO, respectively. Evaluation and validation of the model was performed by simulation via Flexsim software.

Space communications scheduler: A rule-based approach to adaptive deadline scheduling
NASA Technical Reports Server (NTRS)
Straguzzi, Nicholas
1990-01-01
Job scheduling is a deceptively complex subfield of computer science. The highly combinatorial nature of the problem, which is NP-complete in nearly all cases, requires a scheduling program to intelligently transverse an immense search tree to create the best possible schedule in a minimal amount of time. In addition, the program must continually make adjustments to the initial schedule when faced with last-minute user requests, cancellations, unexpected device failures, quests, cancellations, unexpected device failures, etc. A good scheduler must be quick, flexible, and efficient, even at the expense of generating slightly less-than-optimal schedules. The Space Communication Scheduler (SCS) is an intelligent rule-based scheduling system. SCS is an adaptive deadline scheduler which allocates modular communications resources to meet an ordered set of user-specified job requests on board the NASA Space Station. SCS uses pattern matching techniques to detect potential conflicts through algorithmic and heuristic means. As a result, the system generates and maintains high density schedules without relying heavily on backtracking or blind search techniques. SCS is suitable for many common real-world applications.
Cost-effectiveness of rotavirus vaccination in peru.

2009-11-01
There are plans to introduce the oral rotavirus vaccine Rotarix (GlaxoSmithKline), 1 of 2 recently developed vaccines against rotavirus, in Peru. We modeled the cost-effectiveness of adding a rotavirus vaccine to the Peruvian immunization program under 3 scenarios for the timing of vaccination: (1) strictly according to schedule, at 2 and 4 months of age (on time); (2) distributed around the target ages in the same way as the actual timings in the program (flexible); and (3) flexible but assuming vaccination is not initiated for infants >12 weeks of age (restricted). We assumed an introductory price of US $7.50 per dose, and varied the annual rate of price decrease in sensitivity analyses. The discounted cost per disability-adjusted life-year averted for restricted, flexible, and on-time schedules was $621, $615, and $581, respectively. For each of the 3 scenarios, the percentage reduction in deaths due to rotavirus infection was 53%, 66%, and 69%, respectively. The cost per disability-adjusted life-year averted for alternative "what-if" scenarios ranged from $229 (assuming a 1-dose schedule, administered on time) to $1491 (assuming a 2-dose schedule, with half the baseline vaccine efficacy rates and a restricted timing policy). On the basis of current World Health Organization guidelines, rotavirus vaccination represents a highly cost-effective intervention in Peru. Withholding the vaccine from children who present for their first dose after 12 weeks of age would reduce the number of deaths averted by approximately 20%. A single dose may be more cost-effective than 2 doses, but more evidence on the protection conferred by a single dose is required.

NDCX-II is an accelerator facility being built at LBNL to study ion-heated warm dense matter and aspects of ion-driven targets for inertial-fusion energy. The baseline design calls for using twelve induction cells to accelerate 40 nC of Li+ ions to 1.2 MeV. During commissioning, though, we plan to extend the source lifetime by extracting less total charge. For operational flexibility, the option of using a helium plasma source is also being investigated. Over time, we expect that NDCX-II will be upgraded to substantially higher energies, necessitating the use of heavier ions to keep a suitable deposition range in targets. Each of these options requires development of an alternate acceleration schedule and the associated transverse focusing. The schedules here are first worked out with a fast-running 1-D particle-in-cell code ASP, then 2-D and 3-D Warp simulations are used to verify the 1-D results and to design transverse focusing. Work performed under the auspices of U.S. Department of Energy by LLNL under Contract DE-AC52-07NA27344 and by LBNL under Contract DE-AC03-76SF00098.

Over the last three years, we have been investigating the operational concept of crew self-scheduling as a method of increasing crew autonomy for future exploration missions. Through Playbook, a planning and scheduling software tool, we have incrementally increased the ability for Earth analog mission crews to modify their schedules. Playbook allows the crew to add new activities from scratch, add new activities or groups of activities through a Task List, and reschedule or reassign flexible activities. The crew is also able to identify if plan modifications create violations, i.e., plan constraints not being met. This paper summarizes our observations with qualitative evidence from four NASA Extreme Environment Mission Operations (NEEMO) analog missions that supported self-scheduling as a feasible operational concept.

Planning and scheduling systems organize tasks into a timeline or schedule. Tasks are logically grouped into containers called models. Models are a collection of related tasks, along with their dependencies and requirements, that when met will produce the desired result. One challenging domain for a planning and scheduling system is the operation of on-board experiments for the International Space Station. In these experiments, the equipment used is among the most complex hardware ever developed; the information sought is at the cutting edge of scientific endeavor; and the procedures are intricate and exacting. Scheduling is made more difficult by a scarcity of station resources. The models to be fed into the scheduler must describe both the complexity of the experiments and procedures (to ensure a valid schedule) and the flexibilities of the procedures and the equipment (to effectively utilize available resources). Clearly, scheduling International Space Station experiment operations calls for a maximally expressive modeling schema.
DTS: Building custom, intelligent schedulers

Hansson, Othar; Mayer, Andrew
1994-01-01
DTS is a decision-theoretic scheduler, built on top of a flexible toolkit -- this paper focuses on how the toolkit might be reused in future NASA mission schedulers. The toolkit includes a user-customizable scheduling interface, and a 'Just-For-You' optimization engine. The customizable interface is built on two metaphors: objects and dynamic graphs. Objects help to structure problem specifications and related data, while dynamic graphs simplify the specification of graphical schedule editors (such as Gantt charts). The interface can be used with any 'back-end' scheduler, through dynamically-loaded code, interprocess communication, or a shared database. The 'Just-For-You' optimization engine includes user-specific utility functions, automatically compiled heuristic evaluations, and a postprocessing facility for enforcing scheduling policies. The optimization engine is based on BPS, the Bayesian Problem-Solver (1,2), which introduced a similar approach to solving single-agent and adversarial graph search problems.

To effectively manage a project, the project manager must have a plan, understand the current conditions, and be able to take action to correct the course when challenges arise. Research and design projects face technical, schedule, and budget challenges that make it difficult to utilize project management tools developed for projects based on previously demonstrated technologies. Projects developing new technologies by their inherent nature are trying something new and thus have little to no data to support estimates for schedule and cost, let alone the technical outcome. Projects with a vision for the outcome but little confidence in the exact tasks to accomplish in order to achieve the vision incur cost and schedule penalties when conceptual solutions require unexpected iterations or even a reinvention of the plan. This presentation will share the project management methodology and tools developed through trial and error for a NASA research and design project combining industry, academia, and NASA inhouse work in which Earned Value Management principles were employed but adapted for the reality of the government financial system and the reality of challenging technology development. The priorities of the presented methodology are flexibility, accountability, and simplicity to give the manager tools to help deliver to the customer while not using up valuable time and resources on extensive planning and analysis. This presentation will share the methodology, tools, and work through failed and successful examples from the three years of process evolution.

The intercollegiate setting receives much of the scholarly attention related to work-life conflict (WLC). However research has been focused on the National Collegiate Athletic Association Division I setting. Multiple factors can lead to WLC for the athletic trainer (AT), including hours, travel, and lack of flexibility in work schedules. To investigate the experiences of WLC among ATs working in the non-Division I collegiate setting and to identify factors that contribute to fulfillment of work-life balance in this setting. Qualitative study. Institutions in the National Collegiate Athletic Association Divisions II and III, the National Association of Intercollegiate Athletics, and the National Junior College Athletic Association. A total of 244 ATs (128 women, 114 men; age = 37.5 ± 13.3 years, experience = 14 ± 12 years) completed phase I. Thirteen participants (8 women, 5 men; age = 38 ± 13 years, experience = 13.1 ± 11.4 years) completed phase II. For phase I, participants completed a previously validated and reliable (Cronbach α > .90) Web-based survey measuring their levels of WLC and work-family conflict (WFC). This phase included 2 WFC scales defining family; scale 1 defined family as having a partner or spouse with or without children, and scale 2 defined family as those individuals, including parents, siblings, grandparents, and any other close relatives, involved in one's life. Phase II consisted of an interview. Qualitative data were evaluated using content analysis. Data source and multiple-analyst triangulation secured credibility. The WFC scores were 26.33 ± 7.37 for scale 1 and 20.46 ± 10.14 for scale 2, indicating a moderate level of WFC for scale 1 and a low level of WFC for scale 2. Qualitative analyses revealed that organizational dimensions, such as job demands and staffing issues, can negatively affect WLC, whereas a combination of organizational and personal dimensions can positively affect WLC. Overload continues to be a prevalent factor in negatively influencing WLC and WFC. Supervisor and peer support, personal networks, and time away from the role positively influenced work-life balance and WFC. Athletic trainers are encouraged to support one another in the workplace, especially when providing flexibility in scheduling.

One of the limiting factors that have prevented a widely dissemination of the reconfigurable technology is the absence of an appropriate model for certain target applications capable of offering a reliable control. Moreover, the lack of flexible and easy-to-use scheduling and management systems are also relevant drawbacks to be considered. Under static scenarios, it is relatively easy to schedule and manage the reconfiguration process since all the variations corresponding to predetermined and well-known tasks. However, the difficulty increases when the adaptation needs of the overall system change semi-randomly according to the environmental fluctuations. In this context, this work proposes a change in the paradigm of dynamically reconfigurable systems, by attending to the dynamically reconfigurable control problematic as a whole, in which the scheduling and the placement issues are packed together as a hierarchical management structure, interacting together as one entity from the system point of view, but performing their tasks with certain degree of independence each other. In this sense, the top hierarchical level corresponds with a dynamic scheduler in charge of planning and adjusting all the reconfigurable modules according to the variations of the external stimulus. The lower level interacts with the physical layer of the device by means of instantiating, relocating, removing a reconfigurable module following the scheduler's instructions. In regards to how fast is the proposed solution, the total partial reconfiguration time achieved with this proposal has been measured and compared with other two approaches: 1) using traditional Xilinx's tools; 2) using an optimized version of the Xilinx's drivers. The collected numbers demonstrate that our solution reaches a gain up to 10 times faster than the other approaches.

Deadlock-free control and scheduling are vital for optimizing the performance of automated manufacturing systems (AMSs) with shared resources and route flexibility. Based on the Petri net models of AMSs, this paper embeds the optimal deadlock avoidance policy into the genetic algorithm and develops a novel deadlock-free genetic scheduling algorithm for AMSs. A possible solution of the scheduling problem is coded as a chromosome representation that is a permutation with repetition of parts. By using the one-step look-ahead method in the optimal deadlock control policy, the feasibility of a chromosome is checked, and infeasible chromosomes are amended into feasible ones, which can be easily decoded into a feasible deadlock-free schedule. The chromosome representation and polynomial complexity of checking and amending procedures together support the cooperative aspect of genetic search for scheduling problems strongly.

The aim of this study was to assess the relationship between exposure to physical and organizational job stressors during pregnancy and cesarean delivery. We sampled 580 employed women in California who participated in a nested population-based case-control study of birth outcomes. Adjusted multivariate regression analyses estimated associations between heavy lifting, frequent bending, high noise, extreme temperature, prolonged standing and organizational stressors (shift work, inflexible schedules, effort-reward ratio), and primary cesarean (vs vaginal) delivery, controlling for covariates. Women occupationally exposed had higher odds of cesarean. Those exposed to daily manual lifting more than 15 pounds [adjusted odds ratio = 2.54; 95% confidence interval (95% CI) 1.21 to 5.32] and at least four physical job stressors (adjusted odds ratio = 3.49; 95% CI 1.21 to 10.09) had significantly elevated odds of cesarean delivery. Exposed morbid women experienced greater risk; risk was lower among those with schedule flexibility. Associations were found between modifiable exposure to physical job stressors during pregnancy and cesarean delivery.

NDCX-II is a newly completed accelerator facility at LBNL, built to study ion-heated warm dense matter and aspects of ion-driven targets for inertial-fusion energy. The baseline design calls for using twelve induction cells to accelerate 40 nC of Li+ ions to 1.2 MeV. During commissioning, though, we plan to extend the source lifetime by extracting less total charge. For operational flexibility, the option of using a helium plasma source is also being investigated. Over time, we expect that NDCX-II will be upgraded to substantially higher energies, necessitating the use of heavier ions to keep a suitable deposition range in targets. Each of these options requires development of an alternate acceleration schedule and the associated transverse focusing. The schedules here are first worked out with a fast-running 1-D particle-in-cell code ASP, then 2-D and 3-D Warp simulations are used to verify the 1-D results and to design transverse focusing.

1. Support of key decision makers is critical to the successful implementation of a corporate wellness program. Therefore, the program implementation plan must be communicated in a format and language readily understood by business people. 2. A business approach to corporate wellness program planning provides a standardized way to communicate the implementation plan. 3. A business approach incorporates the program planning components in a format that ranges from general to specific. This approach allows for flexibility and responsiveness to changes in program planning. 4. Components of the business approach are the executive summary, purpose, background, ground rules, approach, requirements, scope of work, schedule, and financials.

Work schedules contribute substantially to the health and well-being of nurses. Too broad typologies are used in research that do not meet the current variety in work schedules. To develop a new typology for nurses' work schedules based on five requirements and to validate the typology. This study is based on a questionnaire returned by 498 nurses (response 51%) including questions regarding nurses' work schedule, socio-demographic, and family characteristics and their appraisal of the work schedule. Frequencies of the different schedules were computed to determine the typology. To validate the typology, differences between the types were tested with ANOVAs, Chi2 and Kruskal-Wallis tests. Five main types can be distinguished based on predetermined requirements and frequencies, namely: (1) fixed early shift, (2) rotating two shift pattern without night shift, (3) rotating three shift pattern, (4) fixed and rotating two shift pattern including night shift, and (5) fixed normal day or afternoon shifts. Nurses in these types of work schedule differed significantly with respect to hours worked, days off between shifts, age, education, years in the job, commuting time, contribution to household income, satisfaction with work schedule and work schedule control. Especially nurses with type 3 schedules differed from other types. A typology of five main types of work schedules is proposed. Content validity of the typology is sufficient and the new typology seems useful for research on work-related aspects of nursing.
Job sharing: a viable option for the clinical nurse specialist.
Haibeck, S V; Howard, J L
1991-01-01
NUMEROUS WORK TIME options have been developed to attract, retain and meet the various needs of nurses. Job sharing, a work option little known to nurses, can be a successful alternative for balancing professional and personal lifestyle. The business literature supports job sharing and other innovative work options as successful mechanisms in retaining quality employees in their respective professions. After exploring the literature in this area, a proposal for job sharing the oncology clinical nurse specialist (CNS) position was presented to the Personnel Director and Vice President of Nursing at our institution. The proposal addressed the advantages and disadvantages of the concept. These included: (1) scheduling flexibility, (2) reduced absenteeism and turnover, (3) increased productivity, (4) handling fringe benefits, and (5) job satisfaction. The proposal was accepted, and the job sharing position has been successfully implemented for more than 2 years now. This paper describes issues relevant to designing and implementing job sharing in a CNS position.
Effectiveness of e-learning in hospitals.

Because medical personnel share different work shifts (i.e., three work shifts) and do not have a fixed work schedule, implementing timely, flexible, and quick e-learning methods for their continued education is imperative. Hospitals are currently focusing on developing e-learning. This study aims to explore the key factors that influence the effectiveness of e-learning in medical personnel. This study recruited medical personnel as the study participants and collected sample data by using the questionnaire survey method. This study is based on the information systems success model (IS success model), a significant model in MIS research. This study found that the factors (i.e., information quality, service quality, convenience, and learning climate) influence the e-learning satisfaction and in turn influence effectiveness in medical personnel. This study provided recommendations to medical institutions according to the derived findings, which can be used as a reference when establishing e-learning systems in the future.

Certified athletic trainers (ATs) working at the National Collegiate Athletic Association Division I level experience challenges balancing their professional and personal lives. However, an understanding of the strategies ATs use to promote a balance between their professional and personal lives is lacking. To identify the strategies ATs employed in the Division I setting use to establish a balance between their professional and personal lives. Qualitative investigation using inductive content analysis. Athletic trainers employed at Division I schools from 5 National Athletic Trainers' Association districts. A total of 28 (15 women, 13 men) ATs aged 35 ± 9 years volunteered for the study. Asynchronous electronic interviews with follow-up phone interviews. Data were analyzed using inductive content analysis. Peer review, member checking, and data-source triangulation were conducted to establish trustworthiness. Three higher-order themes emerged from the analysis. The initial theme, antecedents of work-family conflict, focused on the demands of the profession, flexibility of work schedules, and staffing patterns as contributing to work-life conflict for this group of ATs. The other 2 emergent higher-order themes, professional factors and personal factors, describe the components of a balanced lifestyle. The second-order theme of constructing the professional factors included both organizational policies and individual strategies, whereas the second-order theme of personal factors was separation of work and life and a supportive personal network. Long work hours, lack of control over work schedules, and unbalanced athlete-to-AT ratios can facilitate conflicts. However, as demonstrated by our results, several organizational and personal strategies can be helpful in creating a balanced lifestyle.
Maximally Expressive Modeling of Operations Tasks

Jaap, John; Richardson, Lea; Davis, Elizabeth
2002-01-01
Planning and scheduling systems organize "tasks" into a timeline or schedule. The tasks are defined within the scheduling system in logical containers called models. The dictionary might define a model of this type as "a system of things and relations satisfying a set of rules that, when applied to the things and relations, produce certainty about the tasks that are being modeled." One challenging domain for a planning and scheduling system is the operation of on-board experiments for the International Space Station. In these experiments, the equipment used is among the most complex hardware ever developed, the information sought is at the cutting edge of scientific endeavor, and the procedures are intricate and exacting. Scheduling is made more difficult by a scarcity of station resources. The models to be fed into the scheduler must describe both the complexity of the experiments and procedures (to ensure a valid schedule) and the flexibilities of the procedures and the equipment (to effectively utilize available resources). Clearly, scheduling International Space Station experiment operations calls for a "maximally expressive" modeling schema.

Aurora is a software system enabling the rapid, easy solution of complex scheduling problems involving spatial and temporal constraints among operations and scarce resources (such as equipment, workspace, and human experts). Although developed for use in the International Space Station Processing Facility, Aurora is flexible enough that it can be easily customized for application to other scheduling domains and adapted as the requirements change or become more precisely known over time. Aurora s scheduling module utilizes artificial-intelligence (AI) techniques to make scheduling decisions on the basis of domain knowledge, including knowledge of constraints and their relative importance, interdependencies among operations, and possibly frequent changes in governing schedule requirements. Unlike many other scheduling software systems, Aurora focuses on resource requirements and temporal scheduling in combination. For example, Aurora can accommodate a domain requirement to schedule two subsequent operations to locations adjacent to a shared resource. The graphical interface allows the user to quickly visualize the schedule and perform changes reflecting additional knowledge or alterations in the situation. For example, the user might drag the activity corresponding to the start of operations to reflect a late delivery.

To establish guidelines for more effectively incorporating part-time faculty into departments of internal medicine, a task force was convened in early 2007 by the Association of Specialty Professors. The task force used informal surveys, current literature, and consensus building among members of the Alliance for Academic Internal Medicine to produce a consensus statement and a series of recommendations. The task force agreed that part-time faculty could enrich a department of medicine, enhance workforce flexibility, and provide high-quality research, patient care, and education in a cost-effective manner. The task force provided a series of detailed steps for operationalizing part-time practice; to do so, key issues were addressed, such as fixed costs, malpractice insurance, space, cross-coverage, mentoring, career development, productivity targets, and flexible scheduling. Recommendations included (1) increasing respect for work-family balance, (2) allowing flexible time as well as part-time employment, (3) directly addressing negative perceptions about part-time faculty, (4) developing policies to allow flexibility in academic advancement, (5) considering part-time faculty as candidates for leadership positions, (6) encouraging granting agencies, including the National Institutes of Health and Veterans Administration, to consider part-time faculty as eligible for research career development awards, and (7) supporting future research in "best practices" for incorporating part-time faculty into academic departments of medicine.

Because of the cluster technology in real-time video transcoding device, the application of facing the massive growth in the number of video assignments and resolution and bit rate of diversity, task scheduling algorithm, and analyze the current mainstream of cluster for real-time video transcoding equipment characteristics of the cluster, combination with the characteristics of the cluster equipment task delay scheduling algorithm is proposed. This algorithm enables the cluster to get better performance in the generation of the job queue and the lower part of the job queue when receiving the operation instruction. In the end, a small real-time video transcode cluster is constructed to analyze the calculation ability, running time, resource occupation and other aspects of various algorithms in operation scheduling. The experimental results show that compared with traditional clustering task scheduling algorithm, task delay scheduling algorithm has more flexible and efficient characteristics.

In this paper, multi-objective flexible job shop scheduling problem (MOFJSP) was studied with the objects to minimize makespan, total workload and critical workload. A variable neighborhood evolutionary algorithm (VNEA) was proposed to obtain a set of Pareto optimal solutions. First, two novel crowded operators in terms of the decision space and object space were proposed, and they were respectively used in mating selection and environmental selection. Then, two well-designed neighborhood structures were used in local search, which consider the problem characteristics and can hold fast convergence. Finally, extensive comparison was carried out with the state-of-the-art methods specially presented for solving MOFJSP on well-known benchmark instances. The results show that the proposed VNEA is more effective than other algorithms in solving MOFJSP.

Time management is the art of arranging, organizing and scheduling one's time for the purpose of generating more effective work and productivity. Scheduling is the process of deciding how to commit resources between varieties of possible tasks. Thus, it is crucial for every organization to have a good work schedule for their staffs. The job of Ward nurses at hospitals runs for 24 hours every day. Therefore, nurses will be working using shift scheduling. This study is aimed to solve the nurse scheduling problem at an emergency ward of a private hospital. A 7-day work schedule for 7 consecutive weeks satisfying all the constraints set by the hospital will be developed using Integer Programming. The work schedule for the nurses obtained gives an optimal solution where all the constraints are being satisfied successfully.

By combining the best of automated and human decision-making in scheduling many advantages can accrue. The joint performance of the user and system is potentially much better than either alone. Features of the MAESTRO scheduling system serve to illustrate concepts of user/software cooperation. MAESTRO may be operated at a user-determinable and dynamic level of autonomy. Because the system allows so much flexibility in the allocation of decision-making responsibilities, and provides users with a wealth of information and other support for their own decision-making, better overall schedules may result.

2010-10-01
This study followed a sample of 217 new mothers in a North Carolina county as they returned to work full-time, measuring their mental and physical health-related quality of life through 16 months postpartum. In general, working mothers of infants had mental health scores that were comparable to the general population of U.S. women, and physical health that was slightly better than women in general. Using ANCOVA and controlling for important demographic characteristics, health-related quality of life was compared between mothers experiencing low and high levels of economic hardship. Across the study period, women with high economic hardship, who constituted 30.7% of the sample, had levels of mental and physical health below those of women with low economic hardship. Mothers with high economic hardship also had less stable health trajectories than mothers with low economic hardship. The findings highlight the importance of reconsidering the traditionally accepted postpartum recovery period of six weeks and extending benefits, such as paid maternity and sick leave, as well as stable yet flexible work schedules.
It can work: Open employment for people with experience of mental illness.
Peterson, Debbie; Gordon, Sarah; Neale, Jenny
2017-01-01
Previous research has tended to focus on the barriers to employment for people with mental illness and the extra support they may need. This research contributes to the knowledge base pertaining to this population by looking at successful employment relationships in New Zealand. To describe factors enabling and/or sustaining the open employment of people with experience of mental illness. Fifteen pairs of employers and employees were interviewed individually but consecutively (using a semi-structured interview schedule) about their perceptions of the critical factors that enabled and sustained the employee's employment. Employee participants were recruited by advertisement, with employers approached through their employees. Transcripts were analysed using a thematic analysis. Themes raised in the interviews included the meaning of work, disclosure of mental illness, the benefits of working, special arrangements or accommodations, the work environment and key things employers and employees do to sustain successful employment. Four critical success factors were identified relating to disclosure, the employment relationship, freedom from discrimination and workplace flexibility.
A real-time computer model to assess resident work-hours scenarios.
McDonald, Furman S; Ramakrishna, Gautam; Schultz, Henry J
2002-07-01
To accurately model residents' work hours and assess options to forthrightly meet Residency Review Committee-Internal Medicine (RRC-IM) requirements. The requirements limiting residents' work hours are clearly defined by the Accreditation Council for Graduate Medical Education (ACGME) and the RRC-IM: "When averaged over any four-week rotation or assignment, residents must not spend more than 80 hours per week in patient care duties."(1) The call for the profession to realistically address work-hours violations is of paramount importance.(2) Unfortunately, work hours are hard to calculate. We developed an electronic model of residents' work-hours scenarios using Microsoft Excel 97. This model allows the input of multiple parameters (i.e., call frequency, call position, days off, short-call, weeks per rotation, outpatient weeks, clinic day of the week, additional time due to clinic) and start and stop times for post-call, non-call, short-call, and weekend days. For each resident on a rotation, the model graphically demonstrates call schedules, plots clinic days, and portrays all possible and preferred days off. We tested the model for accuracy in several scenarios. For example, the model predicted average work hours of 85.1 hours per week for fourth-night-call rotations. This was compared with logs of actual work hours of 84.6 hours per week. Model accuracy for this scenario was 99.4% (95% CI 96.2%-100%). The model prospectively predicted work hours of 89.9 hours/week in the cardiac intensive care unit (CCU). Subsequent surveys found mean CCU work hours of 88, 1 hours per week. Model accuracy for this scenario was 98% (95% CI 93.2-100%). Thus validated, we then used the model to test proposed scenarios for complying with RRC-IM limits. The flexibility of the model allowed demonstration of the full range of work-hours scenarios in every rotation of our 36-month program. Demonstrations of status-quo work-hours scenarios were presented to faculty as well as real-time demonstrations of the feasibility, or unfeasibility, of their proposed solutions. The model clearly demonstrated that non-call (i.e., short-call) admissions without concomitant decreases in overnight call frequency resulted in substantial increases in total work hours. Attempts to "get the resident out" an hour or two earlier each day had negligible effects on total hours and were unrealistic paper solutions. For fourth-night-call rotations, the addition of a "golden weekend" (i.e., a fifth day off per month) was found to significantly reduce work hours. The electronic model allowed the development of creative schedules for previously third-night-call rotations that limit resident work hours without decreasing continuity of care by scheduling overnight call every sixth night alternating with sixth-night-short-call rotations. Our electronic model is sufficiently robust to accurately estimate work hours on multiple and varied rotations. This model clearly demonstrates that it is very difficult to meet the RRC-IM work-hours limitations under standard fourth-night-call schedules with only four days off per month. We are successfully using our model to test proposed alternative scenarios, to overcome faculty misconceptions about resident work-hours "solutions," and to make changes to our call schedules that both are realistic for residents to accomplish and truly diminish total resident work hours toward the requirements of the RRC-IM.

In the literature, the application of multi-objective dynamic scheduling problem and simple priority rules are widely studied. Although these rules are not efficient enough due to simplicity and lack of general insight, composite dispatching rules have a very suitable performance because they result from experiments. In this paper, a dynamic flexible flow line problem with sequence-dependent setup times is studied. The objective of the problem is minimization of mean flow time and mean tardiness. A 0-1 mixed integer model of the problem is formulated. Since the problem is NP-hard, four new composite dispatching rules are proposed to solve it by applying genetic programming framework and choosing proper operators. Furthermore, a discrete-event simulation model is made to examine the performances of scheduling rules considering four new heuristic rules and the six adapted heuristic rules from the literature. It is clear from the experimental results that composite dispatching rules that are formed from genetic programming have a better performance in minimization of mean flow time and mean tardiness than others.
FASTER - A tool for DSN forecasting and scheduling

1993-01-01
FASTER (Forecasting And Scheduling Tool for Earth-based Resources) is a suite of tools designed for forecasting and scheduling JPL's Deep Space Network (DSN). The DSN is a set of antennas and other associated resources that must be scheduled for satellite communications, astronomy, maintenance, and testing. FASTER consists of MS-Windows based programs that replace two existing programs (RALPH and PC4CAST). FASTER was designed to be more flexible, maintainable, and user friendly. FASTER makes heavy use of commercial software to allow for customization by users. FASTER implements scheduling as a two pass process: the first pass calculates a predictive profile of resource utilization; the second pass uses this information to calculate a cost function used in a dynamic programming optimization step. This information allows the scheduler to 'look ahead' at activities that are not as yet scheduled. FASTER has succeeded in allowing wider access to data and tools, reducing the amount of effort expended and increasing the quality of analysis.

A simple approach to robot applications software is described. The idea is to use commercially available software and hardware wherever possible to minimize system costs, schedules and risks. The U.S. has been slow in the adaptation of robots and flexible automation compared to the fluorishing growth of robot implementation in Japan. The U.S. can benefit from this approach because of a more flexible array of vision guided robot technologies.

Sleep disorders among shift workers are common problems due to the disturbed circadian rhythm. The Bergen Shift Work Sleep Questionnaire assesses discrete sleep problems related to work shifts (day, evening and night shifts) and rest days. The aim of the study was to develop the Hungarian version of this questionnaire and to compare the sleep quality of nurses in different work schedules. 326 nurses working in shifts filled in the questionnaire. The authors made convergent and discriminant validation of the questionnaire with the Athens Insomnia Scale and the Perceived Stress Questionnaire. The questionnaire based on psychometric characteristics was suitable to assess sleep disorders associated with shift work in a Hungarian sample. The frequency of discrete symptoms significantly (p<0.001) differed with the shifts. Nurses experienced the worst sleep quality and daytime fatigue after the night shift. Nurses working in irregular shift system had worse sleep quality than nurses working in regular and flexible shift system (p<0.001). The sleep disorder of nurses working in shifts should be assessed with the Hungarian version of the Bergen Shift Work Sleep Questionnaire on a nationally representative sample, and the least burdensome shift system could be established.
Sustainable employability in shiftwork: related to types of work schedule rather than age.
Peters, Velibor; Engels, Josephine A; de Rijk, Angelique E; Nijhuis, Frans J N
2015-10-01
There is scarce research on age and sustainable employability of nurses working in various types of work schedules. Earlier research showed that nurses working in work schedules differ regarding age. Different operationalisations of age might explain variations in sustainable employability. Therefore, the aim of this study was to investigate how nurses working in various types of work schedule differ regarding sustainable employability, and the role that age plays in these differences. Age was defined as chronological age, organisational age, life-span age, and functional age. Questionnaires were distributed to 974 Dutch nurses in residential elder care (response rate 51 %) with questions about the type of work schedule, aspects of sustainable employability, various operationalisations of age, and registered sickness absence data were used. Nurses working in various types of work schedules differed regarding aspects of sustainable employability, also when operationalisations of age were added. The 'life-span age' was directly related to aspects of sustainable employability. Statistically, work ability and job satisfaction were only explained by varying operationalisations of age. Nurses' sustainable employability appeared to be mainly related to differences between the types of work schedule rather than age. Fixed early shifts are characterised by the most positive aspects of sustainable employability, and three rotating schedules score worst. To improve sustainable employability, organisations should implement a system in which nurses with different types of work schedule are monitored in combination with their life-span perspective.
Agents, assemblers, and ANTS: scheduling assembly with market and biological software mechanisms

2000-06-01
Nanoscale assemblers will need robust, scalable, flexible, and well-understood mechanisms such as software agents to control them. This paper discusses assemblers and agents, and proposes a taxonomy of their possible interaction. Molecular assembly is seen as a special case of general assembly, subject to many of the same issues, such as the advantages of convergent assembly, and the problem of scheduling. This paper discusses the contract net architecture of ANTS, an agent-based scheduling application under development. It also describes an algorithm for least commitment scheduling, which uses probabilistic committed capacity profiles of resources over time, along with realistic costs, to provide an abstract search space over which the agents can wander to quickly find optimal solutions.

Systematic Approach to Better Understanding Integration Costs: Preprint

Stark, Gregory B.
2015-09-28
When someone mentions integration costs, thoughts of the costs of integrating renewable generation into an existing system come to mind. We think about how variability and uncertainty can increase power system cycling costs as increasing amounts of wind or solar generation are incorporated into the generation mix. However, seldom do we think about what happens to system costs when new baseload generation is added to an existing system or when generation self-schedules. What happens when a highly flexible combined-cycle plant is added? Do system costs go up, or do they go down? Are other, non-cycling, maintenance costs impacted? In thismore » paper we investigate six technologies and operating practices--including VG, baseload generation, generation mix, gas prices, self-scheduling, and fast-start generation--and how changes in these areas can impact a system's operating costs. This paper provides a working definition of integration costs and four components of variable costs. It describes the study approach and how a production cost modeling-based method was used to determine the cost effects, and, as a part of the study approach section, it describes the test system and data used for the comparisons. Finally, it presents the research findings, and, in closing, suggests three areas for future work.« less

The National School Breakfast Program (SBP) is a federally funded program that allows states to offer nutritious breakfast to K-12 students. However, rates of SBP participation are low in some rural states, and the reasons are not well understood. The purpose of the study was to explore administrators' perceptions, attitudes, and beliefs related to the SBP, and factors they identify as barriers or facilitators to increased participation. Data were collected from a cross-sectional, online survey of K-12 school administrators (N = 152) in a rural, midsized Midwestern state fielded over an academic year. Descriptive statistics were calculated and open-ended questions were coded and analyzed for relevant themes. Administrators identified busing schedules, time constraints, and a lack of flexibility within the school schedule to accommodate breakfast as primary structural barriers to SBP participation. Administrators described family-centered norms as reasons for low participation in rural areas. Administrators are at varying stages of readiness to work on improving participation. Low SBP participation can be explained in part by a convergence of factors related to access, community norms, and structural barriers. Results may be used to inform ways in which administrators at the state, district, and school level can work to increase participation. © 2017, American School Health Association.

SURE (Science User Resource Expert) is one of three components that compose the SURPASS (Science User Resource Planning and Scheduling System). This system is a planning and scheduling tool which supports distributed planning and scheduling, based on resource allocation and optimization. Currently SURE is being used within the SURPASS by the UARS (Upper Atmospheric Research Satellite) SOLSTICE instrument to build a daily science plan and activity schedule and in a prototyping effort with NASA GSFC to demonstrate distributed planning and scheduling for the SOLSTICE II instrument on the EOS platform. For the SOLSTICE application the SURE utilizes a rule-based system. Development of a rule-based program using Ada CLIPS as opposed to using conventional programming, allows for capture of the science planning and scheduling heuristics in rules and provides flexibility in inserting or removing rules as the scientific objectives and mission constraints change. The SURE system's role as a component in the SURPASS, the purpose of the SURE planning and scheduling tool, the SURE knowledge base, and the software architecture of the SURE component are described.

Fountoukis, S. G.; Diomidous, M. J.
2009-08-01
Herein, the design implementation and deployment of an object oriented software system, suitable for the monitoring of cardio surgical departments, is investigated. Distributed design architectures are applied and the implemented software system can be deployed on distributed infrastructures. The software is flexible and adaptable to any cardio surgical environment regardless of the department resources used. The system exploits the relations and the interdependency of the successive bed positions that the patients occupy at the different health care units during their stay in a cardio surgical department, to determine bed availabilities and to perform patient scheduling and instant rescheduling whenever necessary. It also aims to successful monitoring of the workings of the cardio surgical departments in an efficient manner.
Experiencing work as a daily challenge: the case of scleroderma.
Mendelson, Cindy; Poole, Janet L; Allaire, Saralynn
2013-01-01
Little is known about the physical and discretionary aspects of work that people with scleroderma (SSc) find difficult. This article describes the findings from a study that explored the challenges and adaptations made by individuals with SSc to continue to work. Thirty-two employed individuals with SSc participated. Participants were predominantly women (82%), white (79%), and well educated (M = 16.9 years). The average age was 47.3 years, and 60.6% were married. Mean disease duration was 9.7 years, and 56.2% had diffuse SSc. Mean years on the job was 10.2 (SD ± 8.8), and 71.9% worked at least 35 hours per week. Participants engaged in a single structured interview about work-related challenges and adaptations. Content and thematic analysis was used to identify key themes across the interviews. Employees with SSc experienced Work as a daily challenge. This central theme described the general work experience for most participants. Three subthemes described their specific experiences: The work environment: Opportunities, challenges, and accommodations; Career planning; and Supportive others. The participants were anxious to find scenarios that allowed them to continue to work. Worksite accommodations and flexibility in scheduling can make the difference between working and disability.
A study of the work and home domain characteristics of anaesthetists in Nigeria.
Adudu, O P; Amadasun, F E
2008-03-01
To examine the work and home domain characteristics of anaesthetists in Nigeria, and the impact of these on work and family life. A total of 200 self-administered questionnaires were distributed to anaesthetists in various health institutions in Nigeria. Of these, 114 (57%) were returned. Information contained in the questionnaire included demographic characteristics, qualification, rank and years spent in the specialty, spouse occupation and details of work and family life. The 114 respondents consisted of 86 males (77%) and 28 females (22.8%), aged between 30 and 59 years. The average weekly working hours were 58.4 hours. About half of the respondents could study anaesthesia at home sometimes, while 25% each could do so always or not at all. About 41% of the respondents could respond to emergencies at home immediately, while 45% could only do so after first reporting to work. Respondents' recommendation to enhance work and family life included reduced work load, more flexible work schedule, accommodation close to place of work, among others. Positive impact on service output as well as enhanced job satisfaction will ensue if the recommendations in this study are implemented by the relevant authorities.

This paper presents a novel method on the optimization of bi-objective Flexible Job-shop Scheduling Problem (FJSP) under stochastic processing times. The robust counterpart model and the Non-dominated Sorting Genetic Algorithm II (NSGA-II) are used to solve the bi-objective FJSP with consideration of the completion time and the total energy consumption under stochastic processing times. The case study on GM Corporation verifies that the NSGA-II used in this paper is effective and has advantages to solve the proposed model comparing with HPSO and PSO+SA. The idea and method of the paper can be generalized widely in the manufacturing industry, because it can reduce the energy consumption of the energy-intensive manufacturing enterprise with less investment when the new approach is applied in existing systems.

Workforce re-entry for Japanese unemployed dental hygienists.
Usui, Y; Miura, H
2015-02-01
The aim of this study was to define the profile of unemployed dental hygienists who could be enticed to re-enter the workforce and the factors that could facilitate their re-entry into the dental field in Japan. The questionnaire was mailed with a postage-paid return envelope to a sample of 3095 licensed dental hygienists. A 50.4% response rate (S = 1477) was observed. The rate of working dental hygienists was 60.3% (n = 891), and of unemployed dental hygienists was 39.7% (n = 586). Of the latter, 31.9% (n = 187) stated intentions of returning to the workplace. The unemployed dental hygienists seeking employment were more often married and had more children, compared with working dental hygienists currently. This group also had significantly fewer total service years. Moreover, only 11.96% of them belonged to the Japan Dental Hygienists' Association, and 41.3% of those attended training workshops. According to their response, they perceived their top three major barriers to re-entry as 'lack sufficient dental hygiene skill', 'child rearing' and 'poor working atmosphere'. 'Flexibility in the work schedule' and 'location' were the most important factors for re-entry from their perspective. There were not many dental hygienists hoping to return to the dental field. The findings suggested that strategies to encourage non-practicing dental hygienists to re-entry should be emphasized in the areas of a flexible working atmosphere, easy access to information on how to return to practice and guidance on how to maintain professionalism during inactivity. © 2014 John Wiley & Sons A/S.

The objective was to determine baseline characteristics of pediatric residency training programs and academic departments in regard to family-friendly work environments as outlined in the Report of the Task Force on Women in Pediatrics. We conducted Web-based anonymous surveys of 147 pediatric department chairs and 203 pediatric program directors. The chair's questionnaire asked about child care, lactation facilities, family leave policies, work-life balance, and tenure and promotion policies. The program director's questionnaire asked about family leave, parenting, work-life balance, and perceptions of "family-friendliness." The response rate was 52% for program directors and 51% for chairs. Nearly 60% of chairs reported some access to child care or provided assistance locating child care; however, in half of these departments, demand almost always exceeded supply. Lactation facilities were available to breastfeeding faculty in 74% of departments, although only 57% provided access to breast pumps. A total of 78% of chairs and 90% of program directors reported written maternity leave policies with slightly fewer reporting paternity leave policies. The majority (83%) of chairs reported availability of part-time employment, whereas only 27% of program directors offered part-time residency options. Most departments offered some flexibility in promotion and tenure. Although progress has been made, change still is needed in many areas in pediatric departments and training programs, including better accessibility to quality child care; improved lactation facilities for breastfeeding mothers; clear, written parental leave policies; and flexible work schedules to accommodate changing demands of family life.

Parental work schedules and child overweight and obesity.

2012-04-01
Studies in school-age children have consistently shown a positive association between maternal paid work hours and child obesity. However, there is conflicting evidence about the impact of maternal work hours scheduled at nonstandard times (for example, evenings, nights or weekends), and no previous examination of paternal work schedules and child weight. We examined the associations between maternal, paternal and combined parental paid work schedules and overweight/obesity in children at age 9 years. Data were analysed from the most recent follow-up of 9-year-old children (n=434) in an Australian birth cohort study. Children were measured and classified as overweight/obese using the International Obesity Taskforce body mass index cutoff points. Current working conditions of parents were obtained from a structured interview with the primary caregiver. Logistic regression analyses were used to investigate the effect of parental work schedules on child overweight/obesity with adjustment for a range of sociodemographic and household factors associated with parental employment and child weight. At 9 years of age, 99 children (22.8%) were overweight or obese. When parental work schedules were examined separately, child overweight/obesity was significantly associated with paternal nonstandard work schedules (adjusted odds ratio (OR) 1.97, 95% confidence interval (CI) 1.08-3.61). There was no association with any type of maternal work schedule. We also found an association between child overweight/obesity and circumstances in which both parents worked nonstandard schedules; however, this was of borderline statistical significance in the adjusted models (adjusted OR 2.26, 95% CI 0.99-5.16). Work hours scheduled at nonstandard times, when worked by the father or both parents, were associated with child overweight and obesity. These findings indicate the potential importance of fathers' paid work arrangements for child overweight/obesity, which until recently has largely been ignored.

To examine the association between individual (demographic) and organizational (work environment and workload) factors and pharmacists' future work plans and explore reasons for either leaving or staying with current employers (culture/climate factors). Cross-sectional study. United States in 2004. 1,263 pharmacists. Seven-page mail survey. Future work plans, time spent in practice activities, staffing levels, and actual and perceived workload and demographic variables. Overall, 15% of respondents reported that they planned to leave their current employer within the year subsequent to this survey. More than 50% reported that their workload had significantly increased in the previous year. Multivariate analyses showed that nonwhites were 2.1 times more likely to be planning to leave their current employer, compared with whites, and unmarried respondents were 1.7 times more likely to leave than were married individuals. More negative perceptions regarding the impact of workload on various personal, work, and patient care outcomes predicted leaving. A main factor that prompted their inclinations was described by 72% of leavers (insufficient and/or unqualified staff) and 49% of stayers (flexible scheduling). The most common reasons for staying were good salary and relationships with coworkers, while the most common reasons for leaving were a desire for change and stress/workload issues. Future work plans of pharmacists are influenced by a variety of individual, organizational, and culture/climate factors. While employers have little latitude for influencing demographic characteristics of employees, many organizational and culture/climate factors (scheduling, opportunities for interpersonal interactions, salary/benefits, staffing, and workload) can be addressed with the intent of reducing pharmacist turnover.
Employment and work-related issues in cancer survivors.
Mehnert, Anja
2011-02-01
Purpose of this systematic literature review was to identify current knowledge about employment in cancer survivors. Sixty-four studies met inclusion criteria that were original papers published between 01/2000 and 11/2009. Overall, 63.5% of cancer survivors (range 24-94%) returned to work. The mean duration of absence from work was 151 days. Factors significantly associated with a greater likelihood of being employed or return to work were perceived employer accommodation, flexible working arrangements, counseling, training and rehabilitation services, younger age and cancer sites of younger individuals, higher levels of education, male gender, less physical symptoms, lower length of sick leave and continuity of care. Cancer survivors had a significantly increased risk for unemployment, early retirement and were less likely to be re-employed. Between 26% and 53% of cancer survivors lost their job or quit working over a 72-month period post diagnosis. Between 23% and 75% of patients who lost their job were re-employed. A high proportion of patients experienced at least temporary changes in work schedules, work hours, wages and a decline in work ability compared to non-cancer groups.

Liu, Qiang; Wei, Peng; Shang, Zhao-Hui; Ma, Bin; Hu, Yi
2018-01-01
Antarctic Survey Telescopes (AST3) are designed to be fully robotic telescopes at Dome A, Antarctica, which aim for highly efficient time-domain sky surveys as well as rapid response to special transient events (e.g., gamma-ray bursts, near-Earth asteroids, supernovae, etc.). Unlike traditional observations, a well-designed real-time survey scheduler is needed in order to implement an automatic survey in a very efficient, reliable and flexible way for the unattended telescopes. We present a study of the survey strategy for AST3 and implementation of its survey scheduler, which is also useful for other survey projects.
Escalator: An Autonomous Scheduling Scheme for Convergecast in TSCH
Oh, Sukho; Hwang, DongYeop; Kim, Ki-Hyung; Kim, Kangseok
2018-01-01
Time Slotted Channel Hopping (TSCH) is widely used in the industrial wireless sensor networks due to its high reliability and energy efficiency. Various timeslot and channel scheduling schemes have been proposed for achieving high reliability and energy efficiency for TSCH networks. Recently proposed autonomous scheduling schemes provide flexible timeslot scheduling based on the routing topology, but do not take into account the network traffic and packet forwarding delays. In this paper, we propose an autonomous scheduling scheme for convergecast in TSCH networks with RPL as a routing protocol, named Escalator. Escalator generates a consecutive timeslot schedule along the packet forwarding path to minimize the packet transmission delay. The schedule is generated autonomously by utilizing only the local routing topology information without any additional signaling with other nodes. The generated schedule is guaranteed to be conflict-free, in that all nodes in the network could transmit packets to the sink in every slotframe cycle. We implement Escalator and evaluate its performance with existing autonomous scheduling schemes through a testbed and simulation. Experimental results show that the proposed Escalator has lower end-to-end delay and higher packet delivery ratio compared to the existing schemes regardless of the network topology. PMID:29659508

Background The aim of this study was to investigate the burden experienced by nursing personnel working irregular shifts in Greece and to conduct the first test of a Greek version of the Standard Shiftwork Index (SSI). Methods A cross-sectional survey was carried out. The SSI was completed by 365 nurses and nursing assistants working shifts, including nights. Results Female nursing personnel and those suffering from a chronic disease were most affected by working rotating shifts as they had elevated scores on the majority of the SSI scales, such as sleep, chronic fatigue, digestive and cardiovascular problems, general health questionnaire, cognitive and somatic anxiety, shift time satisfaction, engagement and disengagement strategies, languidity, flexibility, and neurotisicm. Nurses with longer working experience and those with family responsibilities also scored higher on some of the SSI scales, such as the sleep, shift time satisfaction, social and domestic disruption, disengagement strategies, morningness, and languidity scales. Conclusion Shiftwork affects female nurses, those with chronic disease, older age, and domestic responsibilities more severely. Therefore management should take these factors into account when designing work schedules to alleviate the burden caused by shiftwork. PMID:25180137

Nurse graduates are leaving their first employment at an alarming rate. The purpose of this study was to explore the relationships between job stress, job satisfaction and related factors over time among these nurses. This study applied a longitudinal design with three follow-ups after nurse graduates' first employment began. Using convenience sampling, participants were 206 new graduates from a university. The Work Environment Nursing Satisfaction Survey and the Clinical Stress Scale were used in this study. Results indicated that job stress remained moderate across three time points. Participants working 12 h shifts exhibited less job stress. Job satisfaction significantly increased in the twelfth month. Participants working 12 h shifts had a higher degree of job satisfaction. Job stress was negatively correlated with job satisfaction. The 12 h work shifts were related to job stress and job satisfaction. These results implied that health-care administrators need to provide longer orientation periods and flexible shift schedules for new graduate nurses to adapt to their work environment. © 2014 Wiley Publishing Asia Pty Ltd.
Software defined multi-OLT passive optical network for flexible traffic allocation

Zhang, Shizong; Gu, Rentao; Ji, Yuefeng; Zhang, Jiawei; Li, Hui
2016-10-01
With the rapid growth of 4G mobile network and vehicular network services mobile terminal users have increasing demand on data sharing among different radio remote units (RRUs) and roadside units (RSUs). Meanwhile, commercial video-streaming, video/voice conference applications delivered through peer-to-peer (P2P) technology are still keep on stimulating the sharp increment of bandwidth demand in both business and residential subscribers. However, a significant issue is that, although wavelength division multiplexing (WDM) and orthogonal frequency division multiplexing (OFDM) technology have been proposed to fulfil the ever-increasing bandwidth demand in access network, the bandwidth of optical fiber is not unlimited due to the restriction of optical component properties and modulation/demodulation technology, and blindly increase the wavelength cannot meet the cost-sensitive characteristic of the access network. In this paper, we propose a software defined multi-OLT PON architecture to support efficient scheduling of access network traffic. By introducing software defined networking technology and wavelength selective switch into TWDM PON system in central office, multiple OLTs can be considered as a bandwidth resource pool and support flexible traffic allocation for optical network units (ONUs). Moreover, under the configuration of the control plane, ONUs have the capability of changing affiliation between different OLTs under different traffic situations, thus the inter-OLT traffic can be localized and the data exchange pressure of the core network can be released. Considering this architecture is designed to be maximum following the TWDM PON specification, the existing optical distribution network (ODN) investment can be saved and conventional EPON/GPON equipment can be compatible with the proposed architecture. What's more, based on this architecture, we propose a dynamic wavelength scheduling algorithm, which can be deployed as an application on control plane and achieve effective scheduling OLT wavelength resources between different OLTs based on various traffic situation. Simulation results show that, by using the scheduling algorithm, network traffic between different OLTs can be optimized effectively, and the wavelength utilization of the multi-OLT system can be improved due to the flexible wavelength scheduling.
Case scheduling preferences of one Surgeon's cataract surgery patients.

The increase in the number of operating rooms nationwide in the United States may reflect preferences of patients for scheduling of outpatient surgery. Yet, little is known of the importance that patients place on scheduling convenience and flexibility. Fifty cataract surgery patients seen by a surgeon at his main office during a 6-mo period responded to a marketing survey. All the patients had Medicare insurance and supplemental insurance permitting surgery at any facility. A telephone questionnaire included four vignettes describing different choices in the scheduling of cataract surgery. Respondents were asked how far they would be willing to travel for one option instead of another. For example, "Your surgery will be on Thursday in three weeks at 2 pm. You can drink water until 9 am. You arrive at 10 am, because your surgery might start early. If you travel farther, you would arrive at 8 am for 9 am surgery." The median (50th percentile) additional travel time was 60 min (lower 95% confidence bound >or=52 min) for each of four options: to receive care on a day chosen by the patient instead of assigned by the physician, to receive care at a single site instead of both the surgeon's office and a surgery center at a different location, to combine the examination and the surgery into a single visit instead of two visits, and to have surgery in the morning instead of the afternoon. The patients of this ophthalmologist placed a high value on convenience and flexibility in scheduling their surgery. In general, this would be achievable only if many operating rooms were available each morning.

The lack of multi-day data for household travel and vehicle capability requirements is an impediment to evaluations of energy savings strategies, since (1) travel requirements vary from day-to-day, and (2) energy-saving transportation options often have reduced capability. This work demonstrates a survey methodology and modeling system for evaluating the energy-savings potential of household travel, considering multi-day travel requirements and capability constraints imposed by the available transportation resources. A stochastic scheduling model is introduced---the multi-day Household Activity Schedule Estimator (mPHASE)---which generates synthetic daily schedules based on "fuzzy" descriptions of activity characteristics using a finite-element representation of activity flexibility, coordination among household members, and scheduling conflict resolution. Results of a thirty-household pilot study are presented in which responses to an interactive computer assisted personal interview were used as inputs to the mPHASE model in order to illustrate the feasibility of generating complex, realistic multi-day household schedules. Study vehicles were equipped with digital cameras and GPS data acquisition equipment to validate the model results. The synthetically generated schedules captured an average of 60 percent of household travel distance, and exhibited many of the characteristics of complex household travel, including day-to-day travel variation, and schedule coordination among household members. Future advances in the methodology may improve the model results, such as encouraging more detailed and accurate responses by providing a selection of generated schedules during the interview. Finally, the Constraints-based Transportation Resource Assignment Model (CTRAM) is introduced. Using an enumerative optimization approach, CTRAM determines the energy-minimizing vehicle-to-trip assignment decisions, considering trip schedules, occupancy, and vehicle capability. Designed to accept either actual or synthetic schedules, results of an application of the optimization model to the 2001 and 2009 National Household Travel Survey data show that U.S. households can reduce energy use by 10 percent, on average, by modifying the assignment of existing vehicles to trips. Households in 2009 show a higher tendency to assign vehicles optimally than in 2001, and multi-vehicle households with diverse fleets have greater savings potential, indicating that fleet modification strategies may be effective, particularly under higher energy price conditions.

2018-05-01
Medical residents continue to experience high rates of burnout during residency training even after implementation of the 2003 Accreditation Council for Graduate Medical Education duty-hour restrictions. The purpose of this study is to determine medical student interest in flexible residency training options. Researchers developed an 11-question survey for second through fourth-year medical students. The populations surveyed included medical students who were: (1) attending the 2015 American Academy of Family Physicians National Conference, the 2015 Family Medicine Midwest Conference, and (2) enrolled at University of Chicago Pritzker School of Medicine, University of Illinois College of Medicine at Chicago, Drexel University College of Medicine, and Case Western Reserve University School of Medicine. The survey was completed by 789 medical students. Over half of medical students surveyed indicated that they would be interested in working part-time during some portion of their residency training (51%), and that access to part-time training options would increase their likelihood of applying to a particular residency program (52%). When given the option of three residency training schedules of varying lengths, 41% of male students and 60% of female students chose a 60-hour workweek, even when that meant extending the residency length by 33% and reducing their yearly salary to $39,000. There is considerable interest among medical students in access to part-time residency training options and reduced-hour residency programs. This level of interest indicates that offering flexible training options could be an effective recruitment tool for residency programs and could improve students' perception of their work-life balance during residency.

High performance computing facilities present unique challenges and opportunities for HEP event processing. The massive scale of many HPC systems means that fractionally small utilization can yield large returns in processing throughput. Parallel applications which can dynamically and efficiently fill any scheduling opportunities the resource presents benefit both the facility (maximal utilization) and the (compute-limited) science. The ATLAS Yoda system provides this capability to HEP-like event processing applications by implementing event-level processing in an MPI-based master-client model that integrates seamlessly with the more broadly scoped ATLAS Event Service. Fine grained, event level work assignments are intelligently dispatched to parallel workers to sustain full utilization on all cores, with outputs streamed off to destination object stores in near real time with similarly fine granularity, such that processing can proceed until termination with full utilization. The system offers the efficiency and scheduling flexibility of preemption without requiring the application actually support or employ check-pointing. We will present the new Yoda system, its motivations, architecture, implementation, and applications in ATLAS data processing at several US HPC centers.
Focus of attention in an activity-based scheduler

Sadeh, Norman; Fox, Mark S.

Earlier research in job shop scheduling has demonstrated the advantages of opportunistically combining order-based and resource-based scheduling techniques. An even more flexible approach is investigated where each activity is considered a decision point by itself. Heuristics to opportunistically select the next decision point on which to focus attention (i.e., variable ordering heuristics) and the next decision to be tried at this point (i.e., value ordering heuristics) are described that probabilistically account for both activity precedence and resource requirement interactions. Preliminary experimental results indicate that the variable ordering heuristic greatly increases search efficiency. While least constraining value ordering heuristics have been advocated in the literature, the experimental results suggest that other value ordering heuristics combined with our variable-ordering heuristic can produce much better schedules without significantly increasing search.
A primary shift rotation nurse scheduling using zero-one linear goal programming.
Huarng, F
1999-01-01
In this study, the author discusses the effect of nurse shift schedules on circadian rhythm and some important ergonomics criteria. The author also reviews and compares different nurse shift scheduling methods via the criteria of flexibility, fairness, continuity in shift assignments, nurses' preferences, and ergonomics principles. In this article, a primary shift rotation system is proposed to provide better continuity in shift assignments to satisfy nurses' preferences. The primary shift rotation system is modeled as a zero-one linear goal programming (LGP) problem. To generate the shift assignment for a unit with 13 nurses, the zero-one LGP model takes less than 3 minutes on average, whereas the head nurses spend approximately 2 to 3 hours on shift scheduling. This study reports the process of implementing the primary shift rotation system.

The purpose of this study was to explore the motivations and stresses associated with full-time working mothers who practice as nurse managers. Full-time work outside the home for mothers has been recognized as a circumstance which may present certain benefits and risks to family life. Nursing management is recognized as a high-stress occupation, which may be filled by mothers who work full time. Little is known about the specific needs and stresses of full-time nurse managers who are caring for children at home. In-depth interviews were conducted with 13 mothers who worked as nurse managers. Participants expressed challenges in several areas including balancing/separating work and home, self-imposed advancement inhibitions, and constant giving. Challenges were offset by assets, which included complimentary roles, health insurance, added income, and professional and personal fulfilment. Participants 'wanted it all', including the conveniences of part-time employment and the benefits of full-time employment. Full-time nurse managers with children at home experience unique tensions which characterize their work and home environments. Employers may assist nurses by adopting flexible scheduling, educational and child-care support and assistance in negotiating work and home roles.

Over the last few decades, the National Collegiate Athletics Association (NCAA) has made changes related to the increase in sanctioned team activities during summer athletics. These changes may affect how athletic training services are provided. To investigate the methods by which athletic training departments of NCAA institutions manage expectations regarding athletic training services during the summer. Mixed-methods qualitative and quantitative study. The NCAA Division I. Twenty-two athletic trainers (13 men, 9 women) participated. All were employed full time within the NCAA Division I setting. Participants were 35 ± 8 years of age (range, 26-52 years), with 12 ± 7 years (range, 3-29 years) of athletic training experience. All participants completed a series of questions online that consisted of closed- (demographic and Likert-scale 5-point) and open-ended items that addressed the research questions. Descriptive statistics, frequency distributions, and phenomenologic analyses were completed with the data. Peer review and multiple-analyst triangulation established credibility. Summer athletic training services included 3 primary mechanisms: individual medical care, shared medical care, or a combination of the 2. Participants reported working 40 ± 10 hours during the summer. Likert-item analysis showed that participants were moderately satisfied with their summer medical care structure (3.3 ± 1.0) and with the flexibility of summer schedules (3.0 ± 1.2). Yet the qualitative analysis revealed that perceptions of summer medical care were more positive for shared-care participants than for individual- or combination-care participants. The perceived effect on the athletic trainer included increased workload and expectations and a negative influence on work-life balance, particularly in terms of decreased schedule flexibility and opportunities for rejuvenation. For many, the summer season mimicked the hours, workload, and expectations of the nontraditional season. The NCAA rule changes and medical care expectations affected the summer workload of athletic trainers, but job sharing seemed to help them manage conflict associated with providing summer athletic training services.

As the number of dental hygiene programs across the country continues to increase, educational opportunities for prospective students have flourished, resulting in increased competition among dental hygiene programs for qualified applicants. The purpose of this study was to provide a current description of dental hygiene students and applicants, assess the reasons for choosing the career, and evaluate the perceptions of both applicants and enrolled students with regard to specific aspects of the profession. A questionnaire was mailed to 142 prospective dental hygiene students who met the minimal requirements for admission to either of the two dental hygiene programs in Arkansas. The prospective students had been invited for an admissions interview. The questionnaire also was administered during class to 80 students currently enrolled in one of the two programs. An overall response rate of 71% (n = 157) was achieved. The average respondent was 22 years old, female, and Caucasian with a grade point average of 3.5 and a composite ACT score of 23. Dental hygiene was also the first career choice and most respondents had prior dental assisting experience. Dental hygienists and dentists were reported as providing the most career guidance, while high school and college guidance counselors were least influential. Respondents chose the profession in order to work with and help people, have flexible work schedules, and receive good salaries. Respondents typically viewed dental hygiene as offering a bright future in terms of job security, good salaries, flexible work schedules, diverse career opportunities, and personal responsibility. No significant difference in overall perceptions of the profession was found between applicants and those enrolled in dental hygiene programs, although the strength of individual perceptions of the profession differed between applicant and first-year students compared to second-year students. Dental hygiene programs can use the findings of this study to identify influential allies in guiding prospective students toward a career in dental hygiene. The results also can be used to design recruitment strategies that incorporate aspects of the profession found to motivate students in their career choice and shape their perceptions of the profession.

Understanding the social network has enabled us to quantitatively study social phenomena such as behaviors in adoption and propagation of information. However, most work has been focusing on networks of large heterogeneous communities, and little attention has been paid to how work-relevant information spreads within networks of small and homogeneous groups of highly trained individuals, such as physicians. Within the professionals, the behavior patterns and the transmission of information relevant to the job are dependent not only on the social network between the employees but also on the schedules and teams that work together. In order to systematically investigate the dependence of the spread of ideas and adoption of innovations on a work-environment network, we sought to construct a model for the interaction network of critical care physicians at Northwestern Memorial Hospital (NMH) based on their work schedules. We inferred patterns and hidden rules from past work schedules such as turnover rates. Using the characteristics of the work schedules of the physicians and their turnover rates, we were able to create multi-year synthetic work schedules for a generic intensive care unit. The algorithm for creating shift schedules can be applied to other schedule dependent networks ARO1.
Parenting Stress among Low-Income and Working-Class Fathers: The Role of Employment
Nomaguchi, Kei; Johnson, Wendi
2014-01-01
Contemporary norms of fatherhood emphasize the dual demands of breadwinning and daily involvement in childcare. Recent qualitative research suggests that working-class fathers find it difficult to meet these demands due to job instability and workplace inflexibility. Yet, little quantitative research has examined how employment characteristics are related to fathers’ parenting stress, in comparison with mothers’. Analyses using data from the Fragile Families and Child Wellbeing Study (N = 3,165) show that unemployment and workplace inflexibility, but not overwork, multiple jobs, odd-jobs, and nonstandard hours, are related to more parenting stress for fathers. Although these two factors are also related to more parenting stress for mothers, nuanced gender differences emerged: these are better predictors than other parental or child characteristics for fathers only, and the effect size of workplace inflexibility is greater for fathers than mothers. In sum, securing a job with flexible schedule is central to reducing fathers’ parenting stress. PMID:27616804

Studies of intimate partner violence (IPV) and work have been primarily conducted with women in low-wage low-status (LWLS) positions, as much of this research has focused on poverty, welfare, and homelessness. Although women in LWLS positions represent a large percentage of working women in the United States, it is also important to investigate experiences of women in high-wage high-status (HWHS) positions because a growing number of women are employed within such jobs. We propose gender role theory can be used to explain occurrences of IPV among women in HWHS positions and their utilization of organizational benefits. We suggest those in HWHS positions may be likely to have access to organizational benefits (e.g., medical, vacation, and flexible work schedules) and the ability to utilize the Family and Medical Leave Act. However, prevailing gender roles existing in organizations may render women in HWHS positions unlikely to use benefits or to take leave.

Due to the features of virtual machine-flexibility, easy controlling and various system environments, more and more fields utilize the virtualization technology to construct the distributed system with the virtual resources, also including high energy physics. This paper introduce a method used in high energy physics that supports multiple resource group and preemptable cloud resource scheduling, combining virtual machine with HTCondor (a batch system). It makes resource controlling more flexible and more efficient and makes resource scheduling independent of job scheduling. Firstly, the resources belong to different experiment-groups, and the type of user-groups mapping to resource-groups(same as experiment-group) is one-to-one or many-to-one. In order to make the confused group simply to be managed, we designed the permission controlling component to ensure that the different resource-groups can get the suitable jobs. Secondly, for the purpose of elastically allocating resources for suitable resource-group, it is necessary to schedule resources like scheduling jobs. So this paper designs the cloud resource scheduling to maintain a resource queue and allocate an appropriate amount of virtual resources to the request resource-group. Thirdly, in some kind of situations, because of the resource occupied for a long time, resources need to be preempted. This paper adds the preemption function for the resource scheduling that implement resource preemption based on the group priority. Additionally, the way to preempting is soft that when virtual resources are preempted, jobs will not be killed but also be held and rematched later. It is implemented with the help of HTCondor, storing the held job information in scheduler, releasing the job to idle status and doing second matcher. In IHEP (institute of high energy physics), we have built a batch system based on HTCondor with a virtual resources pool based on Openstack. And this paper will show some cases of experiment JUNO and LHAASO. The result indicates that multi-group and preemptable resource scheduling is efficient to support multi-group and soft preemption. Additionally, the permission controlling component has been used in the local computing cluster, supporting for experiment JUNO, CMS and LHAASO, and the scale will be expanded to more experiments at the first half year, including DYW, BES and so on. Its evidence that the permission controlling is efficient.

Scheduling is considered as a key task in many industries, such as project based scheduling, crew scheduling, flight scheduling, machine scheduling, etc. In the machine scheduling area, the job shop scheduling problems are considered to be important and highly complex, in which they are characterized as NP-hard. The job shop scheduling problems with late work criterion and non-preemptive jobs are addressed in this paper. Late work criterion is a fairly new objective function. It is a qualitative measure and concerns with late parts of the jobs, unlike classical objective functions that are quantitative measures. In this work, simulated annealing was presented to solve the scheduling problem. In addition, operation based representation was used to encode the solution, and a neighbourhood search structure was employed to search for the new solutions. The case studies are Lawrence instances that were taken from the Operations Research Library. Computational results of this probabilistic meta-heuristic algorithm were compared with a conventional genetic algorithm, and a conclusion was made based on the algorithm and problem.

The fast growing expansion of renewable energy increases the complexities in balancing generation and demand in the power system. The energy-shifting and fast-ramping capability of energy storage has led to increasing interests in batteries to facilitate the integration of renewable resources. In this paper, we present a two-step framework to evaluate the potential value of energy storage in power systems with renewable generation. First, we formulate a stochastic unit commitment approach with wind power forecast uncertainty and energy storage. Second, the solution from the stochastic unit commitment is used to derive a flexible schedule for energy storage in economic dispatchmore » where the look-ahead horizon is limited. Here, analysis is conducted on the IEEE 24-bus system to demonstrate the benefits of battery storage in systems with renewable resources and the effectiveness of the proposed battery operation strategy.« less

Flexible flow shop (or a hybrid flow shop) scheduling problem is an extension of classical flow shop scheduling problem. In a simple flow shop configuration, a job having `g' operations is performed on `g' operation centres (stages) with each stage having only one machine. If any stage contains more than one machine for providing alternate processing facility, then the problem becomes a flexible flow shop problem (FFSP). FFSP which contains all the complexities involved in a simple flow shop and parallel machine scheduling problems is a well-known NP-hard (Non-deterministic polynomial time) problem. Owing to high computational complexity involved in solving these problems, it is not always possible to obtain an optimal solution in a reasonable computation time. To obtain near-optimal solutions in a reasonable computation time, a large variety of meta-heuristics have been proposed in the past. However, tuning algorithm-specific parameters for solving FFSP is rather tricky and time consuming. To address this limitation, teaching-learning-based optimization (TLBO) and JAYA algorithm are chosen for the study because these are not only recent meta-heuristics but they do not require tuning of algorithm-specific parameters. Although these algorithms seem to be elegant, they lose solution diversity after few iterations and get trapped at the local optima. To alleviate such drawback, a new local search procedure is proposed in this paper to improve the solution quality. Further, mutation strategy (inspired from genetic algorithm) is incorporated in the basic algorithm to maintain solution diversity in the population. Computational experiments have been conducted on standard benchmark problems to calculate makespan and computational time. It is found that the rate of convergence of TLBO is superior to JAYA. From the results, it is found that TLBO and JAYA outperform many algorithms reported in the literature and can be treated as efficient methods for solving the FFSP.

Nurses are at very high risk for work-related musculoskeletal injury/disorders (MSD) with low back pain/injury being the most frequently occurring MSD. Nurses are also likely to work extended schedules (long hours, on-call, mandatory overtime, working on days off). The purpose of this study was to examine the relationship of extended work schedules in nurses to MSD. Using a longitudinal, three wave survey of 2,617 registered nurses, Wave 1 work schedule data were related to neck, shoulder, and back (MSD) cases occurring in Waves 2 or 3. Schedule characteristics increasing MSD risk included 13+ hour/days, off-shifts, weekend work, work during time off (while sick, on days off, without breaks), and overtime/on-call. These increases in risk were not explained by psychological demands, but were largely explained by physical demands. Adverse schedules are significantly related to nurse MSD. Healthier schedules, less overtime, and reducing work on days off would minimize risk and recovery time. Copyright (c) 2006 Wiley-Liss, Inc.
An Enabling Technology for New Planning and Scheduling Paradigms
NASA Technical Reports Server (NTRS)
Jaap, John; Davis, Elizabeth
2004-01-01
The Night Projects Directorate at NASA's Marshall Space Flight Center is developing a new planning and scheduling environment and a new scheduling algorithm to enable a paradigm shift in planning and scheduling concepts. Over the past 33 years Marshall has developed and evolved a paradigm for generating payload timelines for Skylab, Spacelab, various other Shuttle payloads, and the International Space Station. The current paradigm starts by collecting the requirements, called ?ask models," from the scientists and technologists for the tasks that are to be scheduled. Because of shortcomings in the current modeling schema, some requirements are entered as notes. Next, a cadre with knowledge of vehicle and hardware modifies these models to encompass and be compatible with the hardware model; again, notes are added when the modeling schema does not provide a better way to represent the requirements. Finally, the models are modified to be compatible with the scheduling engine. Then the models are submitted to the scheduling engine for automatic scheduling or, when requirements are expressed in notes, the timeline is built manually. A future paradigm would provide a scheduling engine that accepts separate science models and hardware models. The modeling schema would have the capability to represent all the requirements without resorting to notes. Furthermore, the scheduling engine would not require that the models be modified to account for the capabilities (limitations) of the scheduling engine. The enabling technology under development at Marshall has three major components: (1) A new modeling schema allows expressing all the requirements of the tasks without resorting to notes or awkward contrivances. The chosen modeling schema is both maximally expressive and easy to use. It utilizes graphical methods to show hierarchies of task constraints and networks of temporal relationships. (2) A new scheduling algorithm automatically schedules the models without the intervention of a scheduling expert. The algorithm is tuned for the constraint hierarchies and the complex temporal relationships provided by the modeling schema. It has an extensive search algorithm that can exploit timing flexibilities and constraint and relationship options. (3) An innovative architecture allows multiple remote users to simultaneously model science and technology requirements and other users to model vehicle and hardware characteristics. The architecture allows the remote users to submit scheduling requests directly to the scheduling engine and immediately see the results. These three components are integrated so that science and technology experts with no knowledge of the vehicle or hardware subsystems and no knowledge of the internal workings of the scheduling engine have the ability to build and submit scheduling requests and see the results. The immediate feedback will hone the users' modeling skills and ultimately enable them to produce the desired timeline. This paper summarizes the three components of the enabling technology and describes how this technology would make a new paradigm possible.

Factors associated with family commitment among pharmacists in the south central U.S. are explored. In 2010, a cross-sectional mailed self-administered 70 item survey of 363 active licensed pharmacists was conducted. This analysis includes only 269 (74%) participants who reported being married. Outcome measures were family commitment (need for family commitment, spouse’s family commitment), work-related characteristics (work challenge, stress, workload, flexibility of work schedule), and job and career satisfaction. Married participants’ mean age was 48 (SD = 18) years; the male to female ratio was 1:1; 73% worked in retail settings and 199 (74%) completed the family commitment questions. Females reported a higher need for family commitment than males (p = 0.02) but there was no significant difference in satisfaction with the commitment. Work challenge and work load were significantly associated with higher need for family commitment (p < 0.01), when controlled for age, gender, number of dependents, work status, and practice setting. Higher work challenge was associated with higher career satisfaction. Higher job related stress was associated with lower job satisfaction. High work challenge and work load may negatively impact family function since married pharmacists would need higher family commitment from their counterparts. The impact of work-family interactions on pharmacy career satisfaction should be further investigated. PMID:28975924

Bioassay criteria for environmental restoration workers

Environmental restoration (ER) work at the U. S. Department of Energy Hanford Site posed questions concerning when to perform bioassay monitoring of workers for potential intakes of radioactivity. Application of criteria originally developed for use inside radionuclide processing facilities to ER work resulted in overly restrictive bioassay requirements. ER work typically involves site characterization or, excavating large quantities of potentially contaminated soil, rather than working with concentrated quantities of radioactivity as in a processing facility. An improved approach, tailored to ER work, provided soil contamination concentrations above which worker bioassay would be required. Soil concentrations were derived assuming acute ormore » chronic intakes of 2% of an Annual Limit on Intake (ALI), or a potential committed effective dose equivalent of 100 mrem, and conservative dust loading of air from the work. When planning ER work, the anticipated soil concentration and corresponding need for bioassay could be estimated from work-site historical records. Once site work commenced, soil sampling and work-place surveys could be used to determine bioassay needs. This approach substantially reduced the required number of bioassay samples with corresponding reductions in analytical costs, schedules, and more flexible work-force management.

As satellite equipment and mission operations become more costly, the drive to keep working equipment running with less labor-power rises. Demonstrating the feasibility of autonomous satellite servicing was the main goal behind the Orbital Express (OE) mission. Like a tow-truck delivering gas to a car on the road, the "servicing" satellite of OE had to find the "client" from several kilometers away, connect directly to the client, and transfer fluid (or a battery) autonomously, while on earth-orbit. The mission met 100% of its success criteria, and proved that autonomous satellite servicing is now a reality for space operations. Planning the satellite mission operations for OE required the ability to create a plan which could be executed autonomously over variable conditions. As the constraints for execution could change weekly, daily, and even hourly, the tools used create the mission execution plans needed to be flexible and adaptable to many different kinds of changes. At the same time, the hard constraints of the plans needed to be maintained and satisfied. The Automated Scheduling and Planning Environment (ASPEN) tool, developed at the Jet Propulsion Laboratory, was used to create the schedule of events in each daily plan for the two satellites of the OE mission. This paper presents an introduction to the ASPEN tool, an overview of the constraints of the OE domain, the variable conditions that were presented within the mission, and the solution to operations that ASPEN provided. ASPEN has been used in several other domains, including research rovers, Deep Space Network scheduling research, and in flight operations for the NASA's Earth Observing One mission's EO1 satellite. Related work is discussed, as are the future of ASPEN and the future of autonomous satellite servicing.

"Please don't tell me that I need to have a baby to have this time off." Those words were still ringing in the ears of Jessica Gonon an hour after a tense meeting with Jana Rowe, one of her key account managers. Jessica, the vice president of sales and customer support at ClarityBase, considered Jana's request for a four-day workweek, for which she was willing to take a corresponding 20% cut in pay. Although the facts seemed simple, the situation was anything but. Just last week, Davis Bennett, another account manager, had made a similar request. He wanted a lighter workload so he could train for the Ironman Triathlon World Championship. Both Jana and Davis were well aware that Megan Flood, another account manager, had been working a reduced schedule for nearly two years. When she was hired, Megan had requested Fridays off to spend time with her two young sons. And since she came highly recommended and the talent pool was tight, Jessica had agreed to the arrangement. The eight account managers at ClarityBase were in charge of helping the company's largest clients install and maintain database applications, which often required no small amount of hand-holding and coddling. Because Megan had an abbreviated schedule, the other account managers were assigned the more difficult clients. But if Jessica agreed to a shorter workweek for Jana and Davis, who would take on the toughest customers? And what would happen if the other account managers started asking for similar deals? How can Jessica maintain the productivity of her department and meet her staff's needs for flexible work schedules while striking an equitable solution for both parents and nonparents? Four experts advise Jessica on her next move in this fictional case study.
Work routines moderate the association between eveningness and poor psychological well-being

Well-being is a useful screening method for the detection of mood disorders. Evidence associating psychological well-being with sleep-wake patterns exists, as well as associations with sleep-wake patterns, work-related parameters, and perceived self-efficacy. Despite the growing research regarding the relationship between these factors and mental health, there are few studies that analyze them together. OBJECTIVE: To investigate if the association between sleep-wake patterns and psychological well-being is mediated or moderated by perceived self-efficacy, work flexibility and work routines. MATERIAL AND METHODS: This cohort study was performed in southern Brazil. A sample of 987 individuals was analyzed (66.9% women; mean age = 43.9 years). Work routines parameters and work schedule flexibility were evaluated, most participants were farmers (46%) and most worked 7 days a week (69.1%). Munich Chronotype Questionnaire (MCTQ) was administered for evaluation of sleep-wake patterns, General Self-Efficacy Scale (GSE) for assessment the participants’ beliefs about how they coped with daily hassles, and World Health Organization Five-item Well-being Index (WHO-5) for evaluation of psychological well-being levels. Moderation and mediation models were tested. RESULTS: The moderation model showed influences of work end time on the relationship between sleep onset time and psychological well-being (R2 = 0.147; F = 24.16; p<0.001). The final regression model showed an association of psychological well-being with sex (Beta = -0.086; p = 0.004), sleep onset time (Beta = -0.086; p = 0.006), and self-efficacy (Beta = 0.316; p<0.001); the work end time showed association in the interaction with sleep onset time (Beta = -0.075; p = 0.016). CONCLUSION: The findings support the direct association of psychological well-being with sleep-wake patterns and self-efficacy, and show an interaction between work routines and sleep-wake patterns. Our results draw attention to the importance of the interplay between individual and social rhythms in relation to psychological well-being. PMID:29624593

The Ground Processing Scheduling System (GPSS) computer program is used to develop streamlined schedules for the inspection, repair, and refurbishment of space shuttles at Kennedy Space Center. A scheduling computer program is needed because space-shuttle processing is complex and it is frequently necessary to modify schedules to accommodate unanticipated events, unavailability of specialized personnel, unexpected delays, and the need to repair newly discovered defects. GPSS implements constraint-based scheduling algorithms and provides an interactive scheduling software environment. In response to inputs, GPSS can respond with schedules that are optimized in the sense that they contain minimal violations of constraints while supporting the most effective and efficient utilization of space-shuttle ground processing resources. The present version of GPSS is a product of re-engineering of a prototype version. While the prototype version proved to be valuable and versatile as a scheduling software tool during the first five years, it was characterized by design and algorithmic deficiencies that affected schedule revisions, query capability, task movement, report capability, and overall interface complexity. In addition, the lack of documentation gave rise to difficulties in maintenance and limited both enhanceability and portability. The goal of the GPSS re-engineering project was to upgrade the prototype into a flexible system that supports multiple- flow, multiple-site scheduling and that retains the strengths of the prototype while incorporating improvements in maintainability, enhanceability, and portability.

In 2011 the U.S. Accreditation Council for Graduate Medical Education began limiting first year resident physicians (interns) to shifts of ≤16 consecutive hours. Controversy persists regarding the effectiveness of this policy for reducing errors and accidents while promoting education and patient care. Using a mathematical model of the effects of circadian rhythms and length of time awake on objective performance and subjective alertness, we quantitatively compared predictions for traditional intern schedules to those that limit work to ≤ 16 consecutive hours. We simulated two traditional schedules and three novel schedules using the mathematical model. The traditional schedules had extended duration work shifts (≥24 h) with overnight work shifts every second shift (including every third night, Q3) or every third shift (including every fourth night, Q4) night; the novel schedules had two different cross-cover (XC) night team schedules (XC-V1 and XC-V2) and a Rapid Cycle Rotation (RCR) schedule. Predicted objective performance and subjective alertness for each work shift were computed for each individual's schedule within a team and then combined for the team as a whole. Our primary outcome was the amount of time within a work shift during which a team's model-predicted objective performance and subjective alertness were lower than that expected after 16 or 24 h of continuous wake in an otherwise rested individual. The model predicted fewer hours with poor performance and alertness, especially during night-time work hours, for all three novel schedules than for either the traditional Q3 or Q4 schedules. Three proposed schedules that eliminate extended shifts may improve performance and alertness compared with traditional Q3 or Q4 schedules. Predicted times of worse performance and alertness were at night, which is also a time when supervision of trainees is lower. Mathematical modeling provides a quantitative comparison approach with potential to aid residency programs in schedule analysis and redesign.

This study examines the effect of long-hour work schedules and nonstandard shift work (e.g., night and evening shifts) on the ability of injured workers to maintain productive employment following a workplace injury. Analyses were based on 13 years of data from the National Longitudinal Survey of Youth. Multivariate logistic regression analyses were performed with one of ten nonstandard schedules as the independent variable and a particular vocational consequences as the dependent variable. Vocational consequences included being unable to perform normal job duties, temporary job reassignment, working less than full time, filing a workers' compensation claim, and quitting or being fired because of the injury. Covariates in the regression model included age, gender, occupation, industry, and region. The most prominent effects of working a nonstandard schedule were a increased risk of being fired (OR = 1.81; 1.15-2.90 CI 95%), quitting (OR = 1.68; 1.20-2.36 CI 95%), or being unable to work full time (OR = 1.33; 1.08-1.64 CI 95%) following an injury, compared to injured workers in conventional schedules. Schedules involving overtime and long working hours generally had a greater impact on vocational consequences following a workplace injury than did schedules involving night, evening, and other nonstandard shift work. Occupational rehabilitation professionals need to consider the specific type of work schedule when developing effective return-to-work plans for injured workers. Special precautions need to be taken for workers returning to schedules that involve more than 12 h per day, 60 h per week, and long commutes.
An Expert Supervisor For A Robotic Work Cell

1988-02-01
To increase task flexibility in a robotic assembly environment, a hierarchical planning and execution system is being developed which will map user specified 3D part assembly tasks into various target robotic work cells, and execute these tasks efficiently using manipulators and sensors available in the work cell. One level of this hierarchy, the Supervisor, is responsible for assigning subtasks of a system generated Task Plan to a set of task specific Specialists and on-line coordination of the activity of these Specialists to accomplish the user specified assembly. The design of the Supervisor can be broken down into five major functional blocks: resource management; concurrency detection; task scheduling; error recovery; and interprocess communication. The Supervisor implementation has been completed on a VAX 11/750 under a Unix environment. PC card Pick-Insert experiments were performed to test this implementation. To test the robustness of the architecture, the Supervisor was then transported to a new work cell under a VMS environment. The experiments performed under Supervisor control in both implementations are discussed after a brief explanation of the functional blocks of the Supervisor and the other levels in the hierarchy.
Intercell scheduling: A negotiation approach using multi-agent coalitions
NASA Astrophysics Data System (ADS)
Tian, Yunna; Li, Dongni; Zheng, Dan; Jia, Yunde
2016-10-01
Intercell scheduling problems arise as a result of intercell transfers in cellular manufacturing systems. Flexible intercell routes are considered in this article, and a coalition-based scheduling (CBS) approach using distributed multi-agent negotiation is developed. Taking advantage of the extended vision of the coalition agents, the global optimization is improved and the communication cost is reduced. The objective of the addressed problem is to minimize mean tardiness. Computational results show that, compared with the widely used combinatorial rules, CBS provides better performance not only in minimizing the objective, i.e. mean tardiness, but also in minimizing auxiliary measures such as maximum completion time, mean flow time and the ratio of tardy parts. Moreover, CBS is better than the existing intercell scheduling approach for the same problem with respect to the solution quality and computational costs.

As a promising approach to solve the computationally intractable problem, the method based on DNA computing is an emerging research area including mathematics, computer science and molecular biology. The task scheduling problem, as a well-known NP-complete problem, arranges n jobs to m individuals and finds the minimum execution time of last finished individual. In this paper, we use a biologically inspired computational model and describe a new parallel algorithm to solve the task scheduling problem by basic DNA molecular operations. In turn, we skillfully design flexible length DNA strands to represent elements of the allocation matrix, take appropriate biological experiment operations and get solutions of the task scheduling problem in proper length range with less than O(n 2 ) time complexity.

Knowledge of the physiological effects of extended (24 hours or more) work shifts in postgraduate medical training is limited. We aimed to quantify work hours, sleep, and attentional failures among first-year residents (postgraduate year 1) during a traditional rotation schedule that included extended work shifts and during an intervention schedule that limited scheduled work hours to 16 or fewer consecutive hours. Twenty interns were studied during two three-week rotations in intensive care units, each during both the traditional and the intervention schedule. Subjects completed daily sleep logs that were validated with regular weekly episodes (72 to 96 hours) of continuous polysomnography (r=0.94) and work logs that were validated by means of direct observation by study staff (r=0.98). Seventeen of 20 interns worked more than 80 hours per week during the traditional schedule (mean, 84.9; range, 74.2 to 92.1). All interns worked less than 80 hours per week during the intervention schedule (mean, 65.4; range, 57.6 to 76.3). On average, interns worked 19.5 hours per week less (P<0.001), slept 5.8 hours per week more (P<0.001), slept more in the 24 hours preceding each working hour (P<0.001), and had less than half the rate of attentional failures while working during on-call nights (P=0.02) on the intervention schedule as compared with the traditional schedule. Eliminating interns' extended work shifts in an intensive care unit significantly increased sleep and decreased attentional failures during night work hours.

Sanclemente, Paul; French, Robert D.
GE - Aircraft Engines has designed, built, and is operating a flexible turning center for jet engine hardware. Although the plant is in the forefront of manufacturing technology development, it was intended from the start to be a production facility. So while there was much to learn from being involved in all phases of the project, meeting production schedules was, and is, key to its success. This paper reviews the early history of the project and ends with a view of its recent production status.

Career satisfaction and surgical practice patterns among female ophthalmologists.
Jinapriya, Delan; Cockerill, Rhonda; Trope, Graham E
2003-08-01
To identify gender differences in career satisfaction and practice patterns among Ontario ophthalmologists. Survey mailed to all Ontario female ophthalmologists (n = 65) and a random sample of male ophthalmologists (n = 72). Men reported performing more operations per month (p = 0.039) and more operations in the last typical year (p = 0.003). More men than women were doing laser refractive surgery (p = 0.004). There were no gender differences in the proportion performing eye surgery or in the hours worked per week or weeks worked per year. Women reported being primarily responsible for their children for significantly more hours per week than men (p = 0.0003). There were no gender differences in any of the parameters of career satisfaction evaluated: number of hours worked, number of hours in the operating room (OR), balance with personal life, flexibility of work schedules, ability to structure work, relationship with colleagues and relationship with OR staff. Despite spending significantly more hours as the primary supervisor of their children, female ophthalmologists were maintaining the same work week as their male colleagues and reported equal career satisfaction. Further investigation is needed to explore the differences between male and female ophthalmologists in the reported number of operations performed.
Nontraditional work schedules for pharmacists.
Mahaney, Lynnae; Sanborn, Michael; Alexander, Emily
2008-11-15
Nontraditional work schedules for pharmacists at three institutions are described. The demand for pharmacists and health care in general continues to increase, yet significant material changes are occurring in the pharmacy work force. These changing demographics, coupled with historical vacancy rates and turnover trends for pharmacy staff, require an increased emphasis on workplace changes that can improve staff recruitment and retention. At William S. Middleton Memorial Veterans Affairs Hospital in Madison, Wisconsin, creative pharmacist work schedules and roles are now mainstays to the recruitment and retention of staff. The major challenge that such scheduling presents is the 8 hours needed to prepare a six-week schedule. Baylor Medical Center at Grapevine in Dallas, Texas, has a total of 45 pharmacy employees, and slightly less than half of the 24.5 full-time-equivalent staff work full-time, with most preferring to work one, two, or three days per week. As long as the coverage needs of the facility are met, Envision Telepharmacy in Alpine, Texas, allows almost any scheduling arrangement preferred by individual pharmacists or the pharmacist group covering the facility. Staffing involves a great variety of shift lengths and intervals, with shifts ranging from 2 to 10 hours. Pharmacy leaders must be increasingly aware of opportunities to provide staff with unique scheduling and operational enhancements that can provide for a better work-life balance. Compressed workweeks, job-sharing, and team scheduling were the most common types of alternative work schedules implemented at three different institutions.

Schedule-Aware Workflow Management Systems
NASA Astrophysics Data System (ADS)
Mans, Ronny S.; Russell, Nick C.; van der Aalst, Wil M. P.; Moleman, Arnold J.; Bakker, Piet J. M.
Contemporary workflow management systems offer work-items to users through specific work-lists. Users select the work-items they will perform without having a specific schedule in mind. However, in many environments work needs to be scheduled and performed at particular times. For example, in hospitals many work-items are linked to appointments, e.g., a doctor cannot perform surgery without reserving an operating theater and making sure that the patient is present. One of the problems when applying workflow technology in such domains is the lack of calendar-based scheduling support. In this paper, we present an approach that supports the seamless integration of unscheduled (flow) and scheduled (schedule) tasks. Using CPN Tools we have developed a specification and simulation model for schedule-aware workflow management systems. Based on this a system has been realized that uses YAWL, Microsoft Exchange Server 2007, Outlook, and a dedicated scheduling service. The approach is illustrated using a real-life case study at the AMC hospital in the Netherlands. In addition, we elaborate on the experiences obtained when developing and implementing a system of this scale using formal techniques.
A Study on Real-Time Scheduling Methods in Holonic Manufacturing Systems
NASA Astrophysics Data System (ADS)
Iwamura, Koji; Taimizu, Yoshitaka; Sugimura, Nobuhiro
Recently, new architectures of manufacturing systems have been proposed to realize flexible control structures of the manufacturing systems, which can cope with the dynamic changes in the volume and the variety of the products and also the unforeseen disruptions, such as failures of manufacturing resources and interruptions by high priority jobs. They are so called as the autonomous distributed manufacturing system, the biological manufacturing system and the holonic manufacturing system. Rule-based scheduling methods were proposed and applied to the real-time production scheduling problems of the HMS (Holonic Manufacturing System) in the previous report. However, there are still remaining problems from the viewpoint of the optimization of the whole production schedules. New procedures are proposed, in the present paper, to select the production schedules, aimed at generating effective production schedules in real-time. The proposed methods enable the individual holons to select suitable machining operations to be carried out in the next time period. Coordination process among the holons is also proposed to carry out the coordination based on the effectiveness values of the individual holons.

This article addresses simultaneous scheduling of machines, AGVs and tools where machines are allowed to share the tools considering transfer times of jobs and tools between machines, to generate best optimal sequences that minimize makespan in a multi-machine Flexible Manufacturing System (FMS). Performance of FMS is expected to improve by effective utilization of its resources, by proper integration and synchronization of their scheduling. Symbiotic Organisms Search (SOS) algorithm is a potent tool which is a better alternative for solving optimization problems like scheduling and proven itself. The proposed SOS algorithm is tested on 22 job sets with makespan as objective for scheduling of machines and tools where machines are allowed to share tools without considering transfer times of jobs and tools and the results are compared with the results of existing methods. The results show that the SOS has outperformed. The same SOS algorithm is used for simultaneous scheduling of machines, AGVs and tools where machines are allowed to share tools considering transfer times of jobs and tools to determine the best optimal sequences that minimize makespan.
Enabling a New Planning and Scheduling Paradigm
NASA Technical Reports Server (NTRS)
Jaap, John; Davis, Elizabeth
2004-01-01
The Flight Projects Directorate at NASA's Marshall Space Flight Center is developing a new planning and scheduling environment and a new scheduling algorithm to enable a paradigm shift in planning and scheduling concepts. Over the past 33 years Marshall has developed and evolved a paradigm for generating payload timelines for Skylab, Spacelab, various other Shuttle payloads, and the International Space Station. The current paradigm starts by collecting the requirements, called "tasks models," from the scientists and technologists for the tasks that they want to be done. Because of shortcomings in the current modeling schema, some requirements are entered as notes. Next a cadre with knowledge of vehicle and hardware modifies these models to encompass and be compatible with the hardware model; again, notes are added when the modeling schema does not provide a better way to represent the requirements. Finally, another cadre further modifies the models to be compatible with the scheduling engine. This last cadre also submits the models to the scheduling engine or builds the timeline manually to accommodate requirements that are expressed in notes. A future paradigm would provide a scheduling engine that accepts separate science models and hardware models. The modeling schema would have the capability to represent all the requirements without resorting to notes. Furthermore, the scheduling engine would not require that the models be modified to account for the capabilities (limitations) of the scheduling engine. The enabling technology under development at Marshall has three major components. (1) A new modeling schema allows expressing all the requirements of the tasks without resorting to notes or awkward contrivances. The chosen modeling schema is both maximally expressive and easy to use. It utilizes graphics methods to show hierarchies of task constraints and networks of temporal relationships. (2) A new scheduling algorithm automatically schedules the models without the intervention of a scheduling expert. The algorithm is tuned for the constraint hierarchies and the complex temporal relationships provided by the modeling schema. It has an extensive search algorithm which can exploit timing flexibilities and constraint and relationship options. (3) A web-based architecture allows multiple remote users to simultaneously model science and technology requirements and other users to model vehicle and hardware characteristics. The architecture allows the users to submit scheduling requests directly to the scheduling engine and immediately see the results. These three components are integrated so that science and technology experts with no knowledge of the vehicle or hardware subsystems and no knowledge of the internal workings of the scheduling engine have the ability to build and submit scheduling requests and see the results. The immediate feedback will hone the users' modeling skills and ultimately enable them to produce the desired timeline. This paper summarizes the three components of the enabling technology and describes how this technology would make a new paradigm possible.

This paper deals with Flexible Manufacturing System (FMS) production rescheduling due to unavailability of cutting tools caused either of cutting tool failure or life time limit. The FMS consists of parallel identical machines integrated with an automatic material handling system and it runs fully automatically. Each machine has a same cutting tool configuration that consists of different geometrical cutting tool types on each tool magazine. The job usually takes two stages. Each stage has sequential operations allocated to machines considering the cutting tool life. In the real situation, the cutting tool can fail before the cutting tool life is reached. The objective in this paper is to develop a dynamic scheduling algorithm when a cutting tool is broken during unmanned and a rescheduling needed. The algorithm consists of four steps. The first step is generating initial schedule, the second step is determination the cutting tool failure time, the third step is determination of system status at cutting tool failure time and the fourth step is the rescheduling for unfinished jobs. The approaches to solve the problem are complete-reactive scheduling and robust-proactive scheduling. The new schedules result differences starting time and completion time of each operations from the initial schedule.

Process planning and scheduling are important manufacturing planning activities which deal with resource utilization and time span of manufacturing operations. The process plans and the schedules generated in the planning phase shall be modified in the execution phase due to the disturbances in the manufacturing systems. This paper deals with a multi-agent architecture of an integrated and dynamic system for process planning and scheduling for multi jobs. A negotiation protocol is discussed, in this paper, to generate the process plans and the schedules of the manufacturing resources and the individual jobs, dynamically and incrementally, based on the alternative manufacturing processes. The alternative manufacturing processes are presented by the process plan networks discussed in the previous paper, and the suitable process plans and schedules are searched and generated to cope with both the dynamic status and the disturbances of the manufacturing systems. We initiatively combine the heuristic search algorithms of the process plan networks with the negotiation protocols, in order to generate suitable process plans and schedules in the dynamic manufacturing environment. A simulation software has been developed to carry out case studies, aimed at verifying the performance of the proposed multi-agent architecture.

The Orion Crew Exploration Vehicle (CET) is being designed to include significantly more automation capability than either the Space Shuttle or the International Space Station (ISS). In particular, the vehicle flight software has requirements to accommodate increasingly automated missions throughout all phases of flight. A data-driven flight software architecture will provide an evolvable automation capability to sequence through Guidance, Navigation & Control (GN&C) flight software modes and configurations while maintaining the required flexibility and human control over the automation. This flexibility is a key aspect needed to address the maturation of operational concepts, to permit ground and crew operators to gain trust in the system and mitigate unpredictability in human spaceflight. To allow for mission flexibility and reconfrgurability, a data driven approach is being taken to load the mission event plan as well cis the flight software artifacts associated with the GN&C subsystem. A database of GN&C level sequencing data is presented which manages and tracks the mission specific and algorithm parameters to provide a capability to schedule GN&C events within mission segments. The flight software data schema for performing automated mission sequencing is presented with a concept of operations for interactions with ground and onboard crew members. A prototype architecture for fault identification, isolation and recovery interactions with the automation software is presented and discussed as a forward work item.

This paper examines the associations between maternal nonstandard work schedules during infancy and children's early behavior problems, and the extent to which infant temperament may moderate these associations. Hypothesized associations were tested using data from the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care (Phase I). Analyses focused on mothers who returned to work by the time the child was 6 months of age, and who worked an average of at least 35 h per week from 6 through 36 months. At 24 and 36 months, children whose mothers worked a nonstandard schedule had higher internalizing and externalizing behaviors. Modest, albeit inconsistent, evidence suggests that temperamentally reactive children may be more vulnerable to maternal work schedules. Maternal depressive symptoms partially mediated associations between nonstandard maternal work schedules and child behavior outcomes. PMID:19233479

Despite the lack of evidence for effectiveness of the Flexible Assertive Community Treatment (Flexible ACT), the model is considered feasible and is well received by mental health professionals. No current studies have adequately examined mental health professional experiences of working with Flexible ACT. The aim of this study was to explore mental health professional experiences of working with the Flexible ACT model compared with standard care. The study was guided by grounded theory and based on the interviews with 19 theoretically chosen mental health professionals in Swedish urban areas primarily working with consumers with psychosis, who had worked with the Flexible ACT model for at least 6 months. The analysis resulted in the core category: "Flexible ACT and the shared caseload create a common action space" and three main categories: (1) "Flexible ACT fills the need for a systematic approach to crisis intervention"; (2) "Flexible ACT has advantages in the psychosocial working environment"; and (3) "Flexible ACT increases the quality of care". Mental health professionals may benefit from working with the Flexible ACT model through decreased job-strain and stress, increased feeling of being in control over their work situation, and experiences of providing higher quality of care.

[An Exploration of Working Conditions and Flexible System for Hospital Nurses].
Huang, Chung-I; Yu, Chien; Yu, Chin-Cheh
2016-04-01
The lack of sufficient numbers of professional nurses in the healthcare system in Taiwan is an issue that affects the sustainability of this system and that relates closely to working conditions. The present study explores the expectations that nurses hold with regard to working conditions and the operation of a flexible system in hospitals. A literature review and focus-group interviews were used to develop the questionnaire Working Conditions and Flexible System. A total of 1,150 copies of this questionnaire were distributed to practicing nurses using stratified random sampling, with 1,146 valid copies returned for a valid recovery rate of 99.65%. The results show that the expectations of participants concerning working conditions and a flexible system focus on the 6 factors of task, numerical, divisional, temporal, wages, and leading flexibility. The total mean was 4.35 (SD=0.42). The means for the 6 types of flexibility were all greater than 4.0. Participants deemed flexibility to be of high importance. The demographic variables hospital, work location, age, education level, work position, work unit, and total work years all affected the 6 types of flexibility significantly. The present study supports that the retention of nurses is significantly associated with working conditions and the operation of a flexible system. Administrators and mangers must create positive working conditions and a flexible system in order to enhance the retention and career development of nurses.
Advanced Nuclear Fuel Cycle Transitions: Optimization, Modeling Choices, and Disruptions
NASA Astrophysics Data System (ADS)
Carlsen, Robert W.
Many nuclear fuel cycle simulators have evolved over time to help understan the nuclear industry/ecosystem at a macroscopic level. Cyclus is one of th first fuel cycle simulators to accommodate larger-scale analysis with it liberal open-source licensing and first-class Linux support. Cyclus also ha features that uniquely enable investigating the effects of modeling choices o fuel cycle simulators and scenarios. This work is divided into thre experiments focusing on optimization, effects of modeling choices, and fue cycle uncertainty. Effective optimization techniques are developed for automatically determinin desirable facility deployment schedules with Cyclus. A novel method fo mapping optimization variables to deployment schedules is developed. Thi allows relationships between reactor types and scenario constraints to b represented implicitly in the variable definitions enabling the usage o optimizers lacking constraint support. It also prevents wasting computationa resources evaluating infeasible deployment schedules. Deployed power capacit over time and deployment of non-reactor facilities are also included a optimization variables There are many fuel cycle simulators built with different combinations o modeling choices. Comparing results between them is often difficult. Cyclus flexibility allows comparing effects of many such modeling choices. Reacto refueling cycle synchronization and inter-facility competition among othe effects are compared in four cases each using combinations of fleet of individually modeled reactors with 1-month or 3-month time steps. There are noticeable differences in results for the different cases. The larges differences occur during periods of constrained reactor fuel availability This and similar work can help improve the quality of fuel cycle analysi generally There is significant uncertainty associated deploying new nuclear technologie such as time-frames for technology availability and the cost of buildin advanced reactors. Historically, fuel cycle analysis has focused on answerin questions of fuel cycle feasibility and optimality. However, there has no been much work done to address uncertainty in fuel cycle analysis helpin answer questions of fuel cycle robustness. This work develops an demonstrates a methodology for evaluating deployment strategies whil accounting for uncertainty. Techniques are developed for measuring th hedging properties of deployment strategies under uncertainty. Additionally methods for using optimization to automatically find good hedging strategie are demonstrated.
Automating the self-scheduling process of nurses in Swedish healthcare: a pilot study.
Rönnberg, Elina; Larsson, Torbjörn
2010-03-01
Hospital wards need to be staffed by nurses round the clock, resulting in irregular working hours for many nurses. Over the years, the nurses' influence on the scheduling has been increased in order to improve their working conditions. In Sweden it is common to apply a kind of self-scheduling where each nurse individually proposes a schedule, and then the final schedule is determined through informal negotiations between the nurses. This kind of self-scheduling is very time-consuming and does often lead to conflicts. We present a pilot study which aims at determining if it is possible to create an optimisation tool that automatically delivers a usable schedule based on the schedules proposed by the nurses. The study is performed at a typical Swedish nursing ward, for which we have developed a mathematical model and delivered schedules. The results of this study are very promising and suggest continued work along these lines.

Flexible work is now endemic in modern economies. A growing literature both praises work flexibility for accommodating employees' needs and criticizes it for fueling contingency and job insecurity. Although studies have identified varied effects of flexible work, questions remain about the workplace dimensions of flexibility and how occupational workplace health is managed in these workplaces. This paper presents findings from a qualitative study of how managers in the computer software industry situate workplace flexibility and approach worker health. In-depth interviews were conducted with managers (and some workers) at 30 firms in Ontario, Canada. Using a critical discourse analysis approach, we examine managers' optimistic descriptions of flexibility which emphasize how flexible work contributes to workers' life balance. We then contrast this with managers' depictions of flexibility work practices as intense and inescapable. We suggest that the discourse of flexibility, and the work practices they foster, make possible and reinforce an increased intensity of work that is driven by the demands of technological pace and change that characterize the global information technology and computer software industries. Finally, we propose that flexible knowledge work has led to a re-framing of occupational health management involving a focus on what we call "strategies of resilience" that aim to buttress workers' capacities to withstand intensive and uncertain working conditions.

2017-05-01
In a development project, efficient design stream line scheduling is difficult and important owing to large design imprecision and the differences in the skills and skill levels of employees. The relative skill levels of employees are denoted as fuzzy numbers. Multiple execution modes are generated by scheduling different employees for design tasks. An optimization model of a design stream line scheduling problem is proposed with the constraints of multiple executive modes, multi-skilled employees and precedence. The model considers the parallel design of multiple projects, different skills of employees, flexible multi-skilled employees and resource constraints. The objective function is to minimize the duration and tardiness of the project. Moreover, a two-dimensional particle swarm algorithm is used to find the optimal solution. To illustrate the validity of the proposed method, a case is examined in this article, and the results support the feasibility and effectiveness of the proposed model and algorithm.
Dispatch Scheduling to Maximize Exoplanet Detection

Johnson, Samson; McCrady, Nate; MINERVA
2016-01-01
MINERVA is a dedicated exoplanet detection telescope array using radial velocity measurements of nearby stars to detect planets. MINERVA will be a completely robotic facility, with a goal of maximizing the number of exoplanets detected. MINERVA requires a unique application of queue scheduling due to its automated nature and the requirement of high cadence observations. A dispatch scheduling algorithm is employed to create a dynamic and flexible selector of targets to observe, in which stars are chosen by assigning values through a weighting function. I designed and have begun testing a simulation which implements the functions of a dispatch scheduler and records observations based on target selections through the same principles that will be used at the commissioned site. These results will be used in a larger simulation that incorporates weather, planet occurrence statistics, and stellar noise to test the planet detection capabilities of MINERVA. This will be used to heuristically determine an optimal observing strategy for the MINERVA project.

The development of robotics applications for space operations is often restricted by the limited movement available to guided robots. Free ranging robots can offer greater flexibility than physically guided robots in these applications. Presented here is an object oriented approach to path planning and task scheduling for free-ranging robots that allows the dynamic determination of paths based on the current environment. The system also provides task learning for repetitive jobs. This approach provides a basis for the design of free-ranging robot systems which are adaptable to various environments and tasks.

Atmospheric remote sensing by instruments such as spectrometers and interferometers often requires scheduling that is dependent on external factors, for example; time and solar (or lunar) zenith angle. Such instruments manufactured by Bruker often use the software package OPUS, which, while useful, is not flexible enough for automatic, repeated, atmospheric measurements of this nature. In this brief paper, we describe ASAP, a Python tool developed to run our network of Fourier transform interferometers in New Zealand and Antarctica. It allows the automated scheduling of measurements by time, lunar, or solar zenith angle while accounting for weather or other external parameters. There is a wide range of useful functions, all packaged in a simple graphical user interface; it is available on request.

Recommendations are made after 32 interviews, lesson identification, lesson analysis, and mission characteristics identification. The major recommendations are as follows: (1) to develop end-to-end planning and scheduling operations concepts by mission class and to ensure their consideration in system life cycle documentation; (2) to create an organizational infrastructure at the Code 500 level, supported by a Directorate level steering committee with project representation, responsible for systems engineering of end-to-end planning and scheduling systems; (3) to develop and refine mission capabilities to assess impacts of early mission design decisions on planning and scheduling; and (4) to emphasize operational flexibility in the development of the Advanced Space Network, other institutional resources, external (e.g., project) capabilities and resources, operational software and support tools.

Space Transportation System operations managers are being confronted with a unique set of challenges as a result of increasing flight rates, the demand for flight manifest/production schedule flexibility and an emphasis on continued cost reduction. These challenges have created the need for an integrated production planning system that provides managers with the capability to plan, schedule, status and account for an orderly flow of products and services across a large, multi-discipline organization. With increased visibility into the end-to-end production flow for individual and parallel missions in process, managers can assess the integrated impact of changes, identify and measure the interrelationships of resource, schedule, and technical performance requirements and prioritize productivity enhancements.
Scheduling and Pricing for Expected Ramp Capability in Real-Time Power Markets

Ela, Erik; O'Malley, Mark
2016-05-01
Higher variable renewable generation penetrations are occurring throughout the world on different power systems. These resources increase the variability and uncertainty on the system which must be accommodated by an increase in the flexibility of the system resources in order to maintain reliability. Many scheduling strategies have been discussed and introduced to ensure that this flexibility is available at multiple timescales. To meet variability, that is, the expected changes in system conditions, two recent strategies have been introduced: time-coupled multi-period market clearing models and the incorporation of ramp capability constraints. To appropriately evaluate these methods, it is important to assessmore » both efficiency and reliability. But it is also important to assess the incentive structure to ensure that resources asked to perform in different ways have the proper incentives to follow these directions, which is a step often ignored in simulation studies. We find that there are advantages and disadvantages to both approaches. We also find that look-ahead horizon length in multi-period market models can impact incentives. This paper proposes scheduling and pricing methods that ensure expected ramps are met reliably, efficiently, and with associated prices based on true marginal costs that incentivize resources to do as directed by the market. Case studies show improvements of the new method.« less

Flexible job-shop scheduling problem (FJSP) is an NP-hard puzzle which inherits the job-shop scheduling problem (JSP) characteristics. This paper presents a bee evolutionary guiding nondominated sorting genetic algorithm II (BEG-NSGA-II) for multiobjective FJSP (MO-FJSP) with the objectives to minimize the maximal completion time, the workload of the most loaded machine, and the total workload of all machines. It adopts a two-stage optimization mechanism during the optimizing process. In the first stage, the NSGA-II algorithm with T iteration times is first used to obtain the initial population N , in which a bee evolutionary guiding scheme is presented to exploit the solution space extensively. In the second stage, the NSGA-II algorithm with GEN iteration times is used again to obtain the Pareto-optimal solutions. In order to enhance the searching ability and avoid the premature convergence, an updating mechanism is employed in this stage. More specifically, its population consists of three parts, and each of them changes with the iteration times. What is more, numerical simulations are carried out which are based on some published benchmark instances. Finally, the effectiveness of the proposed BEG-NSGA-II algorithm is shown by comparing the experimental results and the results of some well-known algorithms already existed.

An increasing proportion of U.S. workers have family caregiving responsibilities. The purpose of this study was to determine whether employees in extended care settings whose managers are supportive, open, and creative about work-family needs, such as flexibility with work schedules, have lower cardiovascular disease (CVD) risk and longer sleep than their less supported counterparts. From semistructured interviews with managers, we constructed a work-family balance score of manager openness and creativity in dealing with employee work-family needs. Trained interviewers collected survey and physiologic outcome data from 393 employees whose managers had a work-family score. Employee outcomes are sleep duration (actigraphy) and CVD risk assessed by blood cholesterol, high glycosylated hemoglobin/diabetes, blood pressure/hypertension, body-mass index, and tobacco consumption. Employees whose managers were less supportive slept less (29 min/day) and were over twice as likely to have 2 or more CVD risk factors (ORs = 2.1 and 2.03 for low and middle manager work-family scores, respectively) than employees whose managers were most open and creative. Employees who provide direct patient care exhibited particularly elevated CVD risk associated with low manager work-family score. Managers' attitudes and practices may affect employee health, including sleep duration and CVD risk.
Pediatric resident perceptions of family-friendly benefits.
Berkowitz, Carol D; Frintner, Mary Pat; Cull, William L
2010-01-01
The aim of this study was to examine the importance of family-friendly features in residency program selection, benefits offered to and used by residents, and importance of benefits in future job selection. A survey of a random, national sample of 1000 graduating pediatric residents in 2008 was mailed and e-mailed. Survey response rate for graduating resident respondents was 59%. Among the respondents, 76% were women. Thirty-seven percent of men and 32% of women were parents. Residents with children were more likely than residents without children to rate family-friendly characteristics as very important in their residency selection (P < .05). Many residents reported that their programs offered maternity leave (88%), paternity leave (59%), individual flexibility with schedule (63%), and lactation rooms (55%), but fewer reported on-site child care (24%), care for ill children (19%), and part-time residency positions (12%). Among residents reporting availability, 77% of women with children used maternity leave and lactation rooms. Few held part-time residency positions (2%), but many expressed interest (23% of women with children). The majority of residents with and without children reported that flexibility with schedule was important in their future job selection. Most women with children (71%) and many women without children (52%) considered part-time work to be very important in their job selection. Family-friendly benefits are important to residents, particularly those with children. The data provides a benchmark for the availability and use of family-friendly features at pediatric training programs. The data also shows that many residents are unaware if benefits are offered, which suggests a need to make available benefits more transparent to residents.

Perceived versus used workplace flexibility in Singapore: predicting work-family fit.
Jones, Blake L; Scoville, D Phillip; Hill, E Jeffrey; Childs, Geniel; Leishman, Joan M; Nally, Kathryn S
2008-10-01
This study examined the relationship of 2 types of workplace flexibility to work-family fit and work, personal, and marriage-family outcomes using data (N = 1,601) representative of employed persons in Singapore. We hypothesized that perceived and used workplace flexibility would be positively related to the study variables. Results derived from structural equation modeling revealed that perceived flexibility predicted work-family fit; however, used flexibility did not. Work-family fit related positively to each work, personal, and marriage-family outcome; however, workplace flexibility only predicted work and personal outcomes. Findings suggest work-family fit may be an important facilitating factor in the interface between work and family life, relating directly to marital satisfaction and satisfaction in other family relationships. Implications of these findings are discussed. Copyright 2008 APA, all rights reserved.

This paper is a consolidated report on ten major planning and scheduling systems that have been developed by the National Aeronautics and Space Administration (NASA). A description of each system, its components, and how it could be potentially used in private industry is provided in this paper. The planning and scheduling technology represented by the systems ranges from activity based scheduling employing artificial intelligence (AI) techniques to constraint based, iterative repair scheduling. The space related application domains in which the systems have been deployed vary from Space Shuttle monitoring during launch countdown to long term Hubble Space Telescope (HST) scheduling. This paper also describes any correlation that may exist between the work done on different planning and scheduling systems. Finally, this paper documents the lessons learned from the work and research performed in planning and scheduling technology and describes the areas where future work will be conducted.
Work-leave rotation pattern and incidence of offshore workplace injury.
Massey, S
2018-05-17
Studies on work-leave rotation pattern and work place injuries among offshore oil and gas workers have been few and limited to a 2- or 3-week rotation schedule. To examine incidence of workplace injury in relation to the duration of time into work rotation for extended work schedules up to 24 weeks. Six-year injury data on four offshore installations were extracted. Data were analysed for incidence of injury over time and relative risk using linear trend lines and regression. In total, 311 injuries for 1302 workers were analysed, 39% with rotation schedule of 4 weeks work and 4 weeks rest, 27% 8 weeks work and 4 weeks rest, 23% 16 weeks work and 4 weeks rest and 10% 24 weeks work and 4 weeks rest. Incidence of injury decreased as duration of time into the work rotation increased, corrected for exposure, and this was statistically significant for all rotations in first 4 weeks (P < 0.01). Negative correlation between time offshore and injury was observed in all schedules and consistent for age groups, categories of work, shifts and severity of injury. There was no difference in relative risk of injuries between the four schedules, when corrected for exposure and occupational risk of injury. These results are at variance with previous studies, although no prior study has looked beyond 3-week rotation schedule. Longer offshore schedules are safely possible and this could help decrease manpower and logistics costs for oil and gas companies coping with unprecedented low oil prices.
Filling the Holes: Work Schedulers as Job Crafters of Employment Practice in Long-Term Health Care
Kossek, Ellen Ernst; Piszczek, Matthew M.; Mcalpine, Kristie L.; Hammer, Leslie B.; Burke, Lisa
2016-01-01
Although work schedulers serve an organizational role influencing decisions about balancing conflicting stakeholder interests over schedules and staffing, scheduling has primarily been described as an objective activity or individual job characteristic. The authors use the lens of job crafting to examine how schedulers in 26 health care facilities enact their roles as they “fill holes” to schedule workers. Qualitative analysis of interview data suggests that schedulers expand their formal scope and influence to meet their interpretations of how to manage stakeholders (employers, workers, and patients). The authors analyze variations in the extent of job crafting (cognitive, physical, relational) to broaden role repertoires. They find evidence that some schedulers engage in rule-bound interpretation to avoid role expansion. They also identify four types of schedulers: enforcers, patient-focused schedulers, employee-focused schedulers, and balancers. The article adds to the job-crafting literature by showing that job crafting is conducted not only to create meaningful work but also to manage conflicting demands and to mediate among the competing labor interests of workers, clients, and employers.

Normal aging reduces motor synergies in manual pointing.
Verrel, Julius; Lövdén, Martin; Lindenberger, Ulman
2012-01-01
Depending upon its organization, movement variability may reflect poor or flexible control of a motor task. We studied adult age-related differences in the structure of postural variability in manual pointing using the uncontrolled manifold (UCM) method. Participants from 2 age groups (younger: 20-30 years; older: 70-80 years; 12 subjects per group) completed a total of 120 pointing trials to 2 different targets presented according to 3 schedules: blocked, alternating, and random. The age groups were similar with respect to basic kinematic variables, end point precision, as well as the accuracy of the biomechanical forward model of the arm. Following the uncontrolled manifold approach, goal-equivalent and nongoal-equivalent components of postural variability (goal-equivalent variability [GEV] and nongoal-equivalent variability [NGEV]) were determined for 5 time points of the movements (start, 10%, 50%, 90%, and end) and used to define a synergy index reflecting the flexibility/stability aspect of motor synergies. Toward the end of the movement, younger adults showed higher synergy indexes than older adults. Effects of target schedule were not reliable. We conclude that normal aging alters the organization of common multidegree-of-freedom movements, with older adults making less flexible use of motor abundance than younger adults.

Continued growth and expansion of air traffic and increased air carrier economic pressures have mandated greater flexibility and collaboration in air traffic management. The ability of airspace users to select their own routes, so called "free-flight", and to more actively manage their fleet operations for maximum economic advantage are receiving great attention. A first step toward greater airspace user and service provider collaboration is information sharing. In this work, arrival scheduling and airspace management data generated by the NASA/FAA Center/TRACON Automation System (CTAS) and used by the FAA service provider is shared with an airline with extensive operations within the CTAS operational domain. The design and development of a specialized airline CTAS "repeater" system is described, as well as some preliminary results of the impact and benefits of this information on the air carrier's operations. FAA controller per aircraft scheduling information, such as that provided by CTAS, has never before been shared in real-time with an airline. Expected airline benefits include improved fleet planning and arrival gate management, more informed "hold-go" decisions, and avoidance of costly aircraft diversions to alternate airports when faced with uncertain airborne arrival delays.

There is limited evidence of the impact of policies to promote work-family balance on family health. Exploiting the introduction of the UK Flexible Working Act (2003), we examined whether a policy that grants parents the right to request flexible work influences their health and well-being. Using the UK Millennium Cohort Study, we focus on 6424 mothers employed in 2001-2002, when the cohort child was 9 months old, until their child's seventh birthday. We used a difference-in-differences (DiD) approach to compare changes in outcomes before and after the policy among mothers most likely to benefit and mothers unlikely to benefit from the policy. Flexible working increased in a small group of mothers (n=548) whose employer did not offer work flexibility before the reform (treatment group). By contrast, among mothers whose employer already offered flexible work before the reform (control group, n=5810), there was little change or a slight decline in flexible working. DiD estimates suggest that the policy was associated with an increase in flexible working (37.5 percentage points, 95% CI 32.9 to 41.6), but it had no impact on self-rated health (-1.6 percentage points, 95% CI -4.4 to 1.1), long-term illness (-1.87 percentage points, 95% CI -4.3 to 0.5) or life satisfaction scores (β=0.04, 95% CI -0.08 to 0.16). The Flexible Working Act increased flexible working only among a small group of mothers who had not yet the right to request work flexibility, but it had no impact on their health and well-being. Policies promoting work flexibility may require stronger incentives for both parents and employers. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Point-of-Care Test Equipment for Flexible Laboratory Automation.
You, Won Suk; Park, Jae Jun; Jin, Sung Moon; Ryew, Sung Moo; Choi, Hyouk Ryeol
2014-08-01
Blood tests are some of the core clinical laboratory tests for diagnosing patients. In hospitals, an automated process called total laboratory automation, which relies on a set of sophisticated equipment, is normally adopted for blood tests. Noting that the total laboratory automation system typically requires a large footprint and significant amount of power, slim and easy-to-move blood test equipment is necessary for specific demands such as emergency departments or small-size local clinics. In this article, we present a point-of-care test system that can provide flexibility and portability with low cost. First, the system components, including a reagent tray, dispensing module, microfluidic disk rotor, and photometry scanner, and their functions are explained. Then, a scheduler algorithm to provide a point-of-care test platform with an efficient test schedule to reduce test time is introduced. Finally, the results of diagnostic tests are presented to evaluate the system. © 2014 Society for Laboratory Automation and Screening.
Developing a discrete event simulation model for university student shuttle buses

Zulkepli, Jafri; Khalid, Ruzelan; Nawawi, Mohd Kamal Mohd; Hamid, Muhammad Hafizan
2017-11-01
Providing shuttle buses for university students to attend their classes is crucial, especially when their number is large and the distances between their classes and residential halls are far. These factors, in addition to the non-optimal current bus services, typically require the students to wait longer which eventually opens a space for them to complain. To considerably reduce the waiting time, providing the optimal number of buses to transport them from location to location and the effective route schedules to fulfil the students' demand at relevant time ranges are thus important. The optimal bus number and schedules are to be determined and tested using a flexible decision platform. This paper thus models the current services of student shuttle buses in a university using a Discrete Event Simulation approach. The model can flexibly simulate whatever changes configured to the current system and report its effects to the performance measures. How the model was conceptualized and formulated for future system configurations are the main interest of this paper.
Flexible working hours and well-being in Finland.
Kandolin, I; Härmä, M; Toivanen, M
2001-12-01
Flexibility of working hours became more prevalent in the 1990s in Finland. According to a representative survey on Finnish wage and salary earners (n = 1790) at the beginning of 2000, a great majority of male (76%) and female (65%) employees regularly worked overtime and/or had irregular working hours every month. These employees were flexible in meeting the needs of their companies/employers. Individual flexibility of working hours was far less common, only one third of male and female employees were able to regulate their working hours. A better balance between company-controlled and individual flexibility would, however, improve the well-being of employees. Employees working overtime without being allowed to regulate their working hours felt more symptoms of distress and had more conflicts in combining workplace and family roles than those who could individually determine their working hours flexibly. An investment in individually determined flexibility, for example by means of participatory planning, would improve the well-being of employees, and thus also improve the productivity of the organization.

The purpose of the present study was to answer the following research questions: (1) Do workers in different shift schedules differ in mental distress? (2) Do workers in different shift schedules differ in neuroticism? (3) Do shift schedules differ in psychosocial work exposures? (4) Do psychosocial work exposures contribute to mental distress among onshore- and offshore workers? (5) Does neuroticism confound the association between work exposures and mental distress? Workers on six shift-schedules answered a questionnaire (1,471 of 2,628 employees). Psychological and social work factors were measured by QPSNordic, mental distress was measured by HADS and neuroticism was measured by EPQ. The results showed 1) No differences in mental distress between workers in different shift schedules, 2) Revolving-shift workers reported higher neuroticism compared to day workers, 3) Swing-shift workers and revolving-shift workers reported lower job control compared to permanent-night and -day workers, 4) Job demands and role conflict were associated with more mental distress. Job control, role clarity, support, and leadership were associated with lower mental distress, 5) Neuroticism influenced the relationship between psychosocial work factors and mental distress. The present study did not find differences in mental distress between shift schedules. Job characteristics may be contributing factors when determining health effects of shift work. PMID:25740007

Nonstandard working schedules and health: the systematic search for a comprehensive model.

Theoretical models on shift work fall short of describing relevant health-related pathways associated with the broader concept of nonstandard working schedules. Shift work models neither combine relevant working time characteristics applicable to nonstandard schedules nor include the role of rest periods and recovery in the development of health complaints. Therefore, this paper aimed to develop a comprehensive model on nonstandard working schedules to address these shortcomings. A literature review was conducted using a systematic search and selection process. Two searches were performed: one associating the working time characteristics time-of-day and working time duration with health and one associating recovery after work with health. Data extracted from the models were used to develop a comprehensive model on nonstandard working schedules and health. For models on the working time characteristics, the search strategy yielded 3044 references, of which 26 met the inclusion criteria that contained 22 distinctive models. For models on recovery after work, the search strategy yielded 896 references, of which seven met the inclusion criteria containing seven distinctive models. Of the models on the working time characteristics, three combined time-of-day with working time duration, 18 were on time-of-day (i.e. shift work), and one was on working time duration. The model developed in the paper has a comprehensive approach to working hours and other work-related risk factors and proposes that they should be balanced by positive non-work factors to maintain health. Physiological processes leading to health complaints are circadian disruption, sleep deprivation, and activation that should be counterbalanced by (re-)entrainment, restorative sleep, and recovery, respectively, to maintain health. A comprehensive model on nonstandard working schedules and health was developed. The model proposes that work and non-work as well as their associated physiological processes need to be balanced to maintain good health. The model gives researchers a useful overview over the various risk factors and pathways associated with health that should be considered when studying any form of nonstandard working schedule.
Toward a Proof of Concept Cloud Framework for Physics Applications on Blue Gene Supercomputers

Dreher, Patrick; Scullin, William; Vouk, Mladen
2015-09-01
Traditional high performance supercomputers are capable of delivering large sustained state-of-the-art computational resources to physics applications over extended periods of time using batch processing mode operating environments. However, today there is an increasing demand for more complex workflows that involve large fluctuations in the levels of HPC physics computational requirements during the simulations. Some of the workflow components may also require a richer set of operating system features and schedulers than normally found in a batch oriented HPC environment. This paper reports on progress toward a proof of concept design that implements a cloud framework onto BG/P and BG/Q platforms at the Argonne Leadership Computing Facility. The BG/P implementation utilizes the Kittyhawk utility and the BG/Q platform uses an experimental heterogeneous FusedOS operating system environment. Both platforms use the Virtual Computing Laboratory as the cloud computing system embedded within the supercomputer. This proof of concept design allows a cloud to be configured so that it can capitalize on the specialized infrastructure capabilities of a supercomputer and the flexible cloud configurations without resorting to virtualization. Initial testing of the proof of concept system is done using the lattice QCD MILC code. These types of user reconfigurable environments have the potential to deliver experimental schedulers and operating systems within a working HPC environment for physics computations that may be different from the native OS and schedulers on production HPC supercomputers.

The present experiments examined the effect of work requirements in combination with reinforcement schedule on the choice behavior of adults with mental retardation and preschool children. The work requirements of age-appropriate tasks (i.e., sorting silverware, jumping hurdles, tossing beanbags) were manipulated. Participants were presented with their choice of two response options for each trial that varied simultaneously on both work requirement and reinforcement schedule. Results showed that when responding to both choices occurred on the same reinforcement schedule, participants allocated most of their responses to the option with the easier work requirement. When the response option requiring less work was on a leaner reinforcement schedule, most participants shifted their choice to exert more work. There were individual differences across participants regarding their pattern of responding and when they switched from the lesser to the greater work requirement. Data showed that participants' responding was largely controlled by the reinforcement received for responding to each level of work. Various conceptualizations regarding the effects of work requirements on choice behavior are discussed. PMID:9532750

A number of studies have found that control over work conditions and hours is positively related to mental health. Still, potential positive and negative effects of work flexibility remain to be fully explored. On the one hand, higher work flexibility might provide better opportunities for recovery. On the other hand, especially mothers may use flexibility to meet household and family demands. Here, we investigated the association between parent's work flexibility, rated relative to their partner, and emotional exhaustion in interaction with gender. Additionally, gender differences in time use were investigated. Cross-sectional analyses based on responses of employed parents to the 2012 wave of the Swedish Longitudinal Occupational Survey of Health (SLOSH) were conducted ( N = 2,911). Generalized linear models with gamma distribution and a log-link function were used to investigate associations between relative work-flexibility (lower, equal, or higher as compared to partner), gender, and emotional exhaustion. After control for potential confounders, we found that having lower work flexibility than the partner was associated with higher levels of emotional exhaustion as compared to those with higher relative work flexibility. Also, being a mother was associated with higher levels of emotional exhaustion, independent of possible confounders. An interaction effect between low relative work flexibility and gender was found in relation to emotional exhaustion. Regarding time use, clear differences between mothers' and fathers' were found. However, few indications were found that relative work flexibility influenced time use. Mothers spent more time on household chores as compared to fathers, while fathers reported longer working hours. Fathers spent more time on relaxation compared with mothers. To conclude, our results indicate that lower relative work flexibility is detrimental for mental health both for mothers and fathers. However, while gender seems to have a pronounced effect on time use, relative work flexibility seems to have less influence on how time is used. Generally, mothers tend to spend more time on unpaid work while fathers spend longer hours on paid work and report more time for relaxation.

This study examined healthcare managers' perceptions of flexible working arrangements and implementation barriers. Work-life conflict can lead to negative health implications, but flexible working arrangements can help manage this conflict. Little research has examined its implementation in 24/7/365 healthcare organizations or within groups of employees working 9 AM to 5 PM (9-5) versus shift-work hours. Questionnaires regarding perceptions to, benefits of, and barriers against flexible working arrangements were administered to managers of 9-5 workers and shift workers in an Atlantic Canadian healthcare organization. Few differences in perceptions and benefits of flexible working arrangements were found between management groups. However, results indicate that the interaction with patients and/or the immediacy of tasks being performed are barriers for shift-work managers. The nature of healthcare presents barriers for managers implementing flexible working arrangements, which differ only based on whether the job is physical (shift work) versus desk related (9-5 work).

Increasingly, work schedules in retail sales are generated by software that takes into account variations in predicted sales. The resulting variable and unpredictable schedules require employees to be available, unpaid, over extended periods. At the request of a union, we studied schedule preferences in a retail chain in Québec using observations, interviews, and questionnaires. Shift start times had varied on average by four hours over the previous week; 83 percent had worked at least one day the previous weekend. Difficulties with work/life balance were associated with schedules and, among women, with family responsibilities. Most workers wanted: more advance notice; early shifts; regular schedules; two days off in sequence; and weekends off. Choices varied, so software could be adapted to take preferences into account. Also, employers could give better advance notice and establish systems for shift exchanges. Governments could limit store hours and schedule variability while prolonging the minimum sequential duration of leave per week.
Nonstandard Work Schedules, Family Dynamics, and Mother-Child Interactions During Early Childhood.
Prickett, Kate C
2018-03-01
The rising number of parents who work nonstandard schedules has led to a growing body of research concerned with what this trend means for children. The negative outcomes for children of parents who work nonstandard schedules are thought to arise from the disruptions these schedules place on family life, and thus, the types of parenting that support their children's development, particularly when children are young. Using a nationally representative sample of two-parent families (Early Childhood Longitudinal Study-Birth cohort, n = 3,650), this study examined whether mothers' and their partners' nonstandard work schedules were associated with mothers' parenting when children were 2 and 4 years old. Structural equation models revealed that mothers' and their partners' nonstandard work schedules were associated with mothers' lower scores on measures of positive and involved parenting. These associations were mediated by fathers' lower levels of participation in cognitively supportive parenting and greater imbalance in cognitively supportive tasks conducted by mothers versus fathers.

Sensor-scheduling simulation of disparate sensors for Space Situational Awareness
NASA Astrophysics Data System (ADS)
Hobson, T.; Clarkson, I.
2011-09-01
The art and science of space situational awareness (SSA) has been practised and developed from the time of Sputnik. However, recent developments, such as the accelerating pace of satellite launch, the proliferation of launch capable agencies, both commercial and sovereign, and recent well-publicised collisions involving man-made space objects, has further magnified the importance of timely and accurate SSA. The United States Strategic Command (USSTRATCOM) operates the Space Surveillance Network (SSN), a global network of sensors tasked with maintaining SSA. The rapidly increasing number of resident space objects will require commensurate improvements in the SSN. Sensors are scarce resources that must be scheduled judiciously to obtain measurements of maximum utility. Improvements in sensor scheduling and fusion, can serve to reduce the number of additional sensors that may be required. Recently, Hill et al. [1] have proposed and developed a simulation environment named TASMAN (Tasking Autonomous Sensors in a Multiple Application Network) to enable testing of alternative scheduling strategies within a simulated multi-sensor, multi-target environment. TASMAN simulates a high-fidelity, hardware-in-the-loop system by running multiple machines with different roles in parallel. At present, TASMAN is limited to simulations involving electro-optic sensors. Its high fidelity is at once a feature and a limitation, since supercomputing is required to run simulations of appreciable scale. In this paper, we describe an alternative, modular and scalable SSA simulation system that can extend the work of Hill et al with reduced complexity, albeit also with reduced fidelity. The tool has been developed in MATLAB and therefore can be run on a very wide range of computing platforms. It can also make use of MATLAB’s parallel processing capabilities to obtain considerable speed-up. The speed and flexibility so obtained can be used to quickly test scheduling algorithms even with a relatively large number of space objects. We further describe an application of the tool by exploring how the relative mixture of electro-optical and radar sensors can impact the scheduling, fusion and achievable accuracy of an SSA system. By varying the mixture of sensor types, we are able to characterise the main advantages and disadvantages of each configuration.
The skill-divide in job quality: a cross-national analysis of 28 countries.
Stier, Haya
2015-01-01
This study focuses on the skill divide in job quality and the role of social institutions in structuring the relation of workers' qualifications to the attributes of their jobs. Four measures of job quality are examined: job security, job achievement, job content and work schedule flexibility. The study is based on the 2005 ISSP module on work orientations and encompasses 28 countries. Obtained through multilevel modeling, the findings show that low-skilled workers are disadvantaged in all aspects of job quality. However, skill inequality in the quality of employment depends on countries' characteristics, with declining inequality in countries at higher levels of technological development and to some extent also in times of technological growth. At times of high unemployment, skill disparities in job security widen while on other measures of job quality they decline. Under high market regulation, the low skilled enjoy better job security but on other measures, skill inequalities increase. Copyright © 2014 Elsevier Inc. All rights reserved.
Career stress and female managers' health in Taiwan's hospitals: a multilevel model approach.
Chen, Duan-Rung; Lin, Yeh-Yun; Chung, Kuo-Piao
2008-01-01
This study investigates how perception-induced stress (barrier) and social capital (facilitator) affect the health of female managers. On the basis of the responses of 229 valid questionnaires of middle- and high-level female managers in large-scale hospitals, using a multilevel data analysis approach, this study investigates how perception-induced stress and social capital influence self-reported poor health of female managers. Analysis results indicate that all 3 perception-induced stresses (i.e., promotion-related procedural justice, promotion rate, and work-family conflict) and 2 social capital variables (i.e., mentor-assisted promotion and higher ranking mentor in other departments) are significantly associated with the health of female mangers. Factors involving the career success of women also affect their health. Health care organizations expecting to benefit from the long-term contribution of female elites must promote organizational equity and more heavily emphasize flexible work schedules, family-friendly policies, and perception management practices. In addition, adequately designed mentorship practices can greatly benefit female managers.
The effects of shift work on free-living physical activity and sedentary behavior.
Loprinzi, Paul D
2015-07-01
Although occupation may influence physical activity and shift work schedule may influence cardiovascular disease risk factors, our understanding of the effects of shift work schedule on overall physical activity behavior and sedentary behavior is limited. Data from the 2005-2006 National Health and Nutrition Examination Survey were used. Shift work schedule was defined as regular daytime shift, evening, night, rotating or another schedule. Physical activity and sedentary behavior were assessed via accelerometry. 1536 adult participants (≥20years) indicated they currently work and provided data on all study variables. After adjustments, and compared to adults working a regular daytime shift, those working an evening (RR=0.41, p=0.001) and night (RR=0.30, p=0.001) shift, respectively, engaged in 59% and 70% less sustained (bouts) moderate-to-vigorous physical activity, but no differences occurred for overall moderate-to-vigorous physical activity. After adjustments, and compared to those working a regular daytime shift, those working a rotating shift engaged in more light-intensity physical activity (overall: β=26.3min/day; p=0.03; bouts: β=37.5, p=0.01) and less sedentary behavior (β=-28.5min/day, p=0.01). Shift work schedule differentially influences physical activity and sedentary behavior. Physical activity and sedentary intervention strategies may need to be tailored based on shift work schedule.

Many doctors report working excessively demanding schedules that comply with the European Working Time Directive (EWTD). We compared groups of junior doctors working on different schedules in order to identify which features of schedule design most negatively affected their fatigue and well-being in recent weeks. Completed by 336 doctors, the questionnaires focused on the respondents' personal circumstances, work situation, work schedules, sleep, and perceptions of fatigue, work-life balance and psychological strain. Working 7 consecutive nights was associated with greater accumulated fatigue and greater work-life interference, compared with working just 3 or 4 nights. Having only 1 rest day after working nights was associated with increased fatigue. Working a weekend on-call between 2 consecutive working weeks was associated with increased work-life interference. Working frequent on-calls (either on weekends or during the week) was associated with increased work-life interference and psychological strain. Inter-shift intervals of <10 hours were associated with shorter periods of sleep and increased fatigue. The number of hours worked per week was positively associated with work-life interference and fatigue on night shifts. The current findings identify parameters, in addition to those specified in the EWTD, for designing schedules that limit their impact on doctors' fatigue and well-being.

This study compared the effects of a 1 h self-selected recovery period to those of a standard night shift arrangement (with a total break time of 1-h) over a simulated three-day night shift schedule in a laboratory setting. Results showed that the inclusion of the flexible nap scheme resulted in higher performance output, improvements in physiological strain responses and reduced sleepiness during each night shift and generally over the three-night cycle. Certain variables also revealed the impact of napping compared with the standard rest break condition on the circadian rhythm. The sleep diary records show that the inclusion of the current intervention did not significantly reduce daytime recovery sleep. The results suggest that the potential benefits of flexible napping may outweigh the logistical effort it requires in a workplace environment. Consensus on appropriate napping strategies for shift work remains a challenge. This simulated night shift laboratory study sought to determine the effects of a 1-h self-selected nap opportunity relative to a normal shift set-up. The nap improved performance and decreased sleepiness, without affecting daytime sleep.
Flexible data registration and automation in semiconductor production

1997-08-01
The need for cost reduction and flexibility in semiconductor production will result in a wider application of computer based automation systems. With the setup of a new and advanced CMOS semiconductor line in the Fraunhofer Institute for Silicon Technology [ISIT, Itzehoe (D)] a new line information system (LIS) was introduced based on an advanced model for the underlying data structure. This data model was implemented into an ORACLE-RDBMS. A cellworks based system (JOSIS) was used for the integration of the production equipment, communication and automated database bookings and information retrievals. During the ramp up of the production line this new system is used for the fab control. The data model and the cellworks based system integration is explained. This system enables an on-line overview of the work in progress in the fab, lot order history and equipment status and history. Based on this figures improved production and cost monitoring and optimization is possible. First examples of the information gained by this system are presented. The modular set-up of the LIS system will allow easy data exchange with additional software tools like scheduler, different fab control systems like PROMIS and accounting systems like SAP. Modifications necessary for the integration of PROMIS are described.
XOPPS - OEL PROJECT PLANNER/SCHEDULER TOOL
NASA Technical Reports Server (NTRS)
Mulnix, C. L.
1994-01-01
XOPPS is a window-based graphics tool for scheduling and project planning that provides easy and fast on-screen WYSIWYG editing capabilities. It has a canvas area which displays the full image of the schedule being edited. The canvas contains a header area for text and a schedule area for plotting graphic representations of milestone objects in a flexible timeline. XOPPS is object-oriented, but it is unique in its capability for creating objects that have date attributes. Each object on the screen can be treated as a unit for moving, editing, etc. There is a mouse interface for simple control of pointer location. The user can position objects to pixel resolution, but objects with an associated date are positioned automatically in their correct timeline position in the schedule area. The schedule area has horizontal lines across the page with capabilities for multiple pages and for editing the number of lines per page and the line grid. The text on a line can be edited and a line can be moved with all objects on the line moving with it. The timeline display can be edited to plot any time period in a variety of formats from Fiscal year to Calendar Year and days to years. Text objects and image objects (rasterfiles and icons) can be created for placement anywhere on the page. Milestone event objects with a single associated date (and optional text and milestone symbol) and activity objects with start and end dates (and an optional completion date) have unique editing panels for entering data. A representation for schedule slips is also provided with the capability to automatically convert a milestone event to a slip. A milestone schedule on another computer can be saved to an ASCII file to be read by XOPPS. The program can print a schedule to a PostScript file. Dependencies between objects can also be displayed on the chart through the use of precedence lines. This program is not intended to replace a commercial scheduling/project management program. Because XOPPS has an ASCII file interface it can be used in conjunction with a project management tool to produce schedules with a quality appearance. XOPPS is written in C-language for Sun series workstations running SunOS. This package requires MIT's X Window System, Version 11 Revision 4, with OSF/Motif 1.1. A sample executable is included. XOPPS requires 375K main memory and 1.5Mb free disk space for execution. The standard distribution medium is a .25 inch streaming magnetic tape cartridge in UNIX tar format. XOPPS was developed in 1992, based on the Sunview version of OPPS (NPO-18439) developed in 1990. It is a copyrighted work with all copyright vested in NASA.
Real-time design with peer tasks

Goforth, Andre; Howes, Norman R.; Wood, Jonathan D.; Barnes, Michael J.
1995-01-01
We introduce a real-time design methodology for large scale, distributed, parallel architecture, real-time systems (LDPARTS), as an alternative to those methods using rate or dead-line monotonic analysis. In our method the fundamental units of prioritization, work items, are domain specific objects with timing requirements (deadlines) found in user's specification. A work item consists of a collection of tasks of equal priority. Current scheduling theories are applied with artifact deadlines introduced by the designer whereas our method schedules work items to meet user's specification deadlines (sometimes called end-to-end deadlines). Our method supports these scheduling properties. Work item scheduling is based on domain specific importance instead of task level urgency and still meets as many user specification deadlines as can be met by scheduling tasks with respect to urgency. Second, the minimum (closest) on-line deadline that can be guaranteed for a work item of highest importance, scheduled at run time, is approximately the inverse of the throughput, measured in work items per second. Third, throughput is not degraded during overload and instead of resorting to task shedding during overload, the designer can specify which work items to shed. We prove these properties in a mathematical model.
A study of the determinants of work-to-family conflict among hospital nurses in Belgium.
Lembrechts, Lieve; Dekocker, Vickie; Zanoni, Patrizia; Pulignano, Valeria
2015-10-01
This study examines the relative impact of three sources of work-to-family conflict among hospital nurses: work-family policy use (childcare assistance, schedule flexibility, part-time work), job dimensions (work overload, job autonomy, overtime hours, night shifts, regularity in type of shift, weekend work, hierarchical position, variation in tasks) and organisational support (physician/co-worker support). Many studies claim that organisational support and job dimensions are more important sources of work-to-family conflict than work-family policy use, a relation that has not been fully investigated. This study attempts to fill this gap by empirically assessing the relative impact of these sources on nurses' work-to-family conflict. Four hundred and fifty three Belgian nurses completed a web survey. The sources of work-to-family conflict were analysed using a hierarchical linear regression. Organisational support influences work-to-family conflict, above and beyond work-family policy use and job dimensions, while policy use has no influence. Physician and co-worker support have a unique decreasing effect, while work overload and overtime hours increase work-to-family conflict. Organisational support, lack of work overload and absence of overtime hours reduce work-to-family conflict, whereas work-family policy use does not. To retain and attract nurses by reducing work-to-family conflict, hospitals should not (only) rely on work-family policies but should also invest in organisational support and adapted job dimensions. © 2014 John Wiley & Sons Ltd.
Automated observation scheduling for the VLT
NASA Technical Reports Server (NTRS)
Johnston, Mark D.
1988-01-01
It is becoming increasingly evident that, in order to optimize the observing efficiency of large telescopes, some changes will be required in the way observations are planned and executed. Not all observing programs require the presence of the astronomer at the telescope: for those programs which permit service observing it is possible to better match planned observations to conditions at the telescope. This concept of flexible scheduling has been proposed for the VLT: based on current and predicted environmental and instrumental observations which make the most efficient possible use of valuable time. A similar kind of observation scheduling is already necessary for some space observatories, such as Hubble Space Telescope (HST). Space Telescope Science Institute is presently developing scheduling tools for HST, based on the use of artificial intelligence software development techniques. These tools could be readily adapted for ground-based telescope scheduling since they address many of the same issues. The concept are described on which the HST tools are based, their implementation, and what would be required to adapt them for use with the VLT and other ground-based observatories.
Changing Workplaces to Reduce Work-Family Conflict: Schedule Control in a White-Collar Organization
Kelly, Erin L.; Moen, Phyllis; Tranby, Eric
2011-01-01
Work-family conflicts are common and consequential for employees, their families, and work organizations. Can workplaces be changed to reduce work-family conflict? Previous research has not been able to assess whether workplace policies or initiatives succeed in reducing work-family conflict or increasing work-family fit. Using longitudinal data collected from 608 employees of a white-collar organization before and after a workplace initiative was implemented, we investigate whether the initiative affects work-family conflict and fit, whether schedule control mediates these effects, and whether work demands, including long hours, moderate the initiative’s effects on work-family outcomes. Analyses clearly demonstrate that the workplace initiative positively affects the work-family interface, primarily by increasing employees’ schedule control. This study points to the importance of schedule control for our understanding of job quality and for management policies and practices. PMID:21580799

Context: Over the last few decades, the National Collegiate Athletics Association (NCAA) has made changes related to the increase in sanctioned team activities during summer athletics. These changes may affect how athletic training services are provided. Objective: To investigate the methods by which athletic training departments of NCAA institutions manage expectations regarding athletic training services during the summer. Design: Mixed-methods qualitative and quantitative study. Setting: The NCAA Division I. Patients or Other Participants: Twenty-two athletic trainers (13 men, 9 women) participated. All were employed full time within the NCAA Division I setting. Participants were 35 ± 8 years of age (range, 26−52 years), with 12 ± 7 years (range, 3−29 years) of athletic training experience. Data Collection and Analysis: All participants completed a series of questions online that consisted of closed- (demographic and Likert-scale 5-point) and open-ended items that addressed the research questions. Descriptive statistics, frequency distributions, and phenomenologic analyses were completed with the data. Peer review and multiple-analyst triangulation established credibility. Results: Summer athletic training services included 3 primary mechanisms: individual medical care, shared medical care, or a combination of the 2. Participants reported working 40 ± 10 hours during the summer. Likert-item analysis showed that participants were moderately satisfied with their summer medical care structure (3.3 ± 1.0) and with the flexibility of summer schedules (3.0 ± 1.2). Yet the qualitative analysis revealed that perceptions of summer medical care were more positive for shared-care participants than for individual- or combination-care participants. The perceived effect on the athletic trainer included increased workload and expectations and a negative influence on work-life balance, particularly in terms of decreased schedule flexibility and opportunities for rejuvenation. For many, the summer season mimicked the hours, workload, and expectations of the nontraditional season. Conclusions: The NCAA rule changes and medical care expectations affected the summer workload of athletic trainers, but job sharing seemed to help them manage conflict associated with providing summer athletic training services.

Mizell, Carolyn; Malone, Linda
2007-01-01
There is a need for simulation models of software development processes other than the waterfall because processes such as spiral development are becoming more and more popular. The use of a spiral process can make the inherently difficult job of cost and schedule estimation even more challenging due to its evolutionary nature, but this allows for a more flexible process that can better meet customers' needs. This paper will present a discrete event simulation model of spiral development that can be used to analyze cost and schedule effects of using such a process in comparison to a waterfall process.

An algorithm for scheduling works is developed, in which the priority of the work corresponds to the total weight of the subordinate works, the vertices of the graph, and it is proved that for graphs of the tree type the algorithm is optimal. An algorithm is synthesized to reduce the search for solutions when drawing up schedules of construction and installation works, allocating a subset with the optimal solution of the problem of the minimum power, which is determined by the structure of its initial data and numerical values. An algorithm for scheduling construction and installation work is developed, taking into account the schedule for the movement of brigades, which is characterized by the possibility to efficiently calculate the values of minimizing the time of work performance by the parameters of organizational and technological reliability through the use of the branch and boundary method. The program of the computational algorithm was compiled in the MatLAB-2008 program. For the initial data of the matrix, random numbers were taken, uniformly distributed in the range from 1 to 100. It takes 0.5; 2.5; 7.5; 27 minutes to solve the problem. Thus, the proposed method for estimating the lower boundary of the solution is sufficiently accurate and allows efficient solution of the minimax task of scheduling construction and installation works.
