Heuristics for flow shop scheduling : considering non-permutation schedules and a heterogeneous workforce / Heurísticas para escalonamento em flow shops : considerando escalonamentos não-permutacionais e trabalhadores heterogêneos

Benavides Rojas, Alexander Javier January 2015 (has links)
O problema de escalonamento num flow shop (ou flow shop scheduling problem, FSSP) é um modelo de sistemas de produção muito comum que é bem estudado na literatura. No entanto, quase toda a literatura foca-se em escalonamentos permutacionais, desconsiderando soluções ótimas e quase ótimas que são escalonamentos não-permutacionais. Além disso, a prática comum padroniza os tempos de processamento de cada operação, mesmo que estes tempos variem dependendo das diferentes capacidades dos operadores das máquinas, cuja diversidade deve ser considerada no processo de escalonamento quando seja significativa, e.g., em centros de emprego para deficientes (CEDs). Nesta tese, propomos métodos para resolver o FSSP não-permutacional, usando o mesmo tempo e esforço que os métodos do estado da arte usam para o FSSP permutacional, e produzindo escalonamentos não-permutacionais com melhor qualidade do que escalonamentos permutacionais e não-permutacionais produzidos por métodos do estado da arte. Também propomos métodos para resolver o problema combinado de designação de trabalhadores heterogêneos e escalonamento de tarefas num flow shop (ou heterogeneous workforce assignment and flow shop scheduling problem, Het-FSSP), produzindo soluções que compensam as diferentes capacidades e deficiências dos trabalhadores com pequenas perdas nos objetivos da produção. Além do mais, a designação de trabalhadores heterogêneos pode ser integrada em outros problemas de escalonamento, como fizemos com o problema combinado de designação de trabalhadores heterogêneos e escalonamento de tarefas num job shop (ou heterogeneous workforce assignment and job shop scheduling problem, Het-JSSP). / The flow shop scheduling problem (or FSSP) is a very common model of production systems that is well studied in the literature. However, almost all the literature focuses on the permutation FSSP, disregarding optimal and near optimal solutions that are non-permutation schedules. Besides, common practice standardizes the processing times of each operation, even when those times may vary depending on different capabilities of the machine operators, whose diversity must be considered in the scheduling process when it is significant, e.g., in Sheltered Work centers for Disabled (SWDs). In this thesis, we propose methods to solve the non-permutation FSSP, using the same time and effort as state-of-the-art methods for the permutation FSSP, and producing non-permutation schedules with better quality than permutation and non-permutation schedules produced by state-of-the-art methods. We also propose methods to solve the combined heterogeneous workforce assignment and flow shop scheduling problem (or Het-FSSP), producing solutions that compensate the different capabilities and disabilities of the workers with minor or null losses in the productivity objectives. Moreover, the heterogeneous workforce assignment may be integrated into other shop scheduling models, as we did with the heterogeneous workforce assignment and job shop scheduling problem (or Het-JSSP) with similar results.

Social identity reconstruction through education : a program for older women

Hodgins, Grace M. January 1991 (has links)
A substantial number of older women are adversely affected by mild to severe levels of depression. In this study the Social Health Outreach Program (SHOP), an educational intervention originally developed for middle-aged women, was modified and implemented with depressed and non-depressed older women. Through an educative process, participants learned ways to strengthen personal social networks as a means of augmenting social identity and overcoming depression. The purposes of the study were: 1) to measure the impact of SHOP on older women's levels of depression and demoralization, and on their social networks; 2) to determine factors either within or outside of SHOP that helped or hindered their progress during the program; and 3) to describe and analyze their experience of depression. A total of 15 women, aged 58 to 76, participated in a 20 session version of SHOP over a ten week period. Measures of depression and demoralization were obtained before, after and three months following the program; social networks measures were also obtained at three month follow-up. Participants' perceptions about their experience of depression, and about program factors and other concurrent aspects of life that helped or hindered their progress during the program, were obtained in post-program interviews. Outcomes validated SHOP'S approach and demonstrated that with slight modification the program is as effective with older women as it is with mid-life women. Participants who were depressed at pre-test showed a significant decline in depression scores; on measures of demoralization, changes were in the direction expected, although non-significant. Participants reported significant gains to their social networks in terms of people and groups added. Content analysis of interview data yielded 205 helping incidents and 130 hindering incidents that occurred during the program period; from these, 20 categories of factors that advanced participants' progress during the program, and 19 categories of factors that impeded their progress, were determined. This study supported the view that for many older women depression originates in their social environment. The findings validated SHOP'S educational program as a means of increasing social participation, re-constructing social identity and overcoming depression. / Education, Faculty of / Graduate

Finanční analýza internetového obchodu / Financial analysis of an e-shop

Hanáček, Kamil January 2009 (has links)
The aim of this thesis is to create a complex financial analysis that will be useful for the decision making on the future and orientation of the company SEDNISI.CZ, s.r.o.. The theoretical part of the thesis first examines the characteristics of the furniture market and then deals with the analysis of internet use in the Czech Republic. Apart from the financial analysis itself which deals with standard ratio and syntetic indicators the thesis compares the results of the analysed company with results of the whole sector and of one of the competitors. The information gathered from the analysis of financial indicators is further used in the strategic analysis of the company that focuses on revealing the strengths and weaknesses of the company. Despite the fact that the financial and strategic analysis does not perfectly answer every question that is posed to the company it is undoubtedly very useful for evaluating the past developments, for finding problematic areas and for predicting the future of the company.
