Algorithmes approchés pour des problèmes d'ordonnancement multicritères de type job shop flexible et job shop multiressource

Vilcot, Geoffrey 19 November 2007 (has links) (PDF)
Ce travail de thèse s'inscrit dans le cadre d'une collaboration industrielle avec la société Volume Software pour le développement du module d'ordonnancement du logiciel "DirectPlanning". Dans ce travail, nous étudions le problème de job shop flexible multicritère et le problème de job shop multiressource multicritère. Notre objectif est de déterminer une approximation du front de Pareto. Nous avons proposé des algorithmes de résolution approchés et plus particulièrement des algorithmes de recherche Tabou et des algorithmes génétiques. Nous avons proposé différentes versions de nos méthodes pour les deux problèmes considérés. Des expérimentations ont été réalisées et montrent les bonnes performances de nos algorithmes, à la fois d'un point de vue qualité des résultats et d'un point de vue de la rapidité des méthodes.

Juvenile perceptions of shop theft in the Mabopane area

Morodi, Lebogang Richard 31 March 2004 (has links)
This research is a exploratory and descriptive study based on juvenile's perceptions with regard to shop theft. Secondary data sources were consulted to supplement the empirical data collected by means of a comprehensive questionnaire. Five hundred learners from grades 10, 11 and 12 in Mabopane were selected for the completion of the questionnaires. Shop theft was further elucidated by the application of criminological theories to explain research findings by highlighting their relationship with shop theft. Main research findings established that there are significant statistical differences with regard to the learner gender, age and grade as far as their views on shop theft were concerned. Recommendations based on the findings include teaching Criminology at secondary schools, the development of an anti shop theft youth oriented crime prevention program, shop theft educational and awareness programmes, and shoplifter offender prevention programs. / Criminology and Security Science / M.A. (Criminology)

Métodos heurísticos para a programação em flow shop permutacional com tempos de setup separados dos tempos de processamento e independentes da seqüência de tarefas / Heuristic methods for the permutation flow shop scheduling problem with separated, non-batch, and sequence-independent setup times

Thays Josyane Perassoli Boiko 11 June 2008 (has links)
Este trabalho dedica-se ao problema de programação em flow shop permutacional com tempos de setup separados dos tempos de processamento e independentes da seqüência de execução das tarefas com o objetivo de minimizar a duração total da programação (Makespan). Por intermédio de investigações realizadas sobre as características estruturais do problema de programação e sua solução, uma propriedade deste problema é apresentada. Esta propriedade, denominada \"Propriedade LBY\", considerando quaisquer duas tarefas adjacentes Ju e Jv (Ju imediatamente precede Jv) independentemente de suas posições na seqüência de tarefas, fornece, um limitante inferior do tempo de espera para a tarefa Jv entre o fim do seu processamento na máquina Mk e o início do seu processamento na máquina seguinte. Dois novos métodos heurísticos são desenvolvidos, com base na propriedade apresentada e no procedimento de inserção de tarefas dos conhecidos métodos N&M e NEH: um construtivo, denominado BMc; e, um melhorativo, denominado BMm. Os métodos heurísticos propostos são comparados com os métodos heurísticos melhorativos de Cao; Bedworth (1992) e Rajendran; Ziegler (1997), através de um grande número de problemas gerados aleatoriamente. Os tempos de processamento são distribuídos no intervalo [1, 99] e os tempos de setup nos intervalos de [1, 49], [1, 99], [51, 149] e [101, 199]. Os métodos são avaliados quanto à porcentagem de sucesso em obter a melhor solução, ao desvio relativo médio e o tempo médio de computação. Os resultados da experimentação computacional mostram a qualidade do método construtivo BMc e a melhor performance do método melhorativo BMm. Estes resultados são apresentados e discutidos. / This work addresses the permutation flow shop scheduling problem with separated, non-batch, and sequence-independent setup times with the objective of minimizing the total time to complete the schedule (Makespan). Following an investigation of problem structural characteristics and your solution a property of this scheduling problem is presented. This property, denoted by \"Property LBY\", given any two adjacent jobs Ju e Jv (Ju immediately precedes Jv), regardless of their position in the sequence of jobs, provides an lower bound of the waiting time for job Jv between the end of its operations on the machine Mk and the beginning on machine M(k+1). Two news heuristics methods are development, on the basis of the presented property and in the job insertion procedure of the known methods named N&M and NEH: one constructive, denote by BMc; and, one improvement, denote by BMm. The proposed heuristics methods are compared with the improvement heuristics methods of Cao; Bedworth (1992) and Rajendran; Ziegler (1997), by a large number of randomly generated problems. The processing time are sampled from a distribution ranging from [1, 99] and, the setup times are sampled from distributions ranging from [1, 49], [1, 99], [51, 149] and [101, 199]. The methods are evaluated by the percentage of success in find the best solution, the average relative deviation and the average computation time. The results of the computational investigation show the quality of the constructive heuristic method BMc and that the improvement heuristic method BMc outperforms all others. These results are presented and discussed.

Método beam search aplicado ao problema de escalonamento de tarefas flexível / Beam search method applied to the flexible job shop scheduling problem

José Eurípedes Ferreira de Jesus Filho 06 June 2013 (has links)
O Job Shop Scheduling Problem é um problema NP-Difícil que chama a atenção de muitos pesquisadores devido seu desafio matemático e sua aplicabilidade em contextos reais. Geralmente, principalmente em cenários próximos aos de fábricas e indústrias, obter um escalonamento ótimo por meio de métodos computacionais exatos implica em um alto desprendimento de tempo. Em contrapartida, devido às exigências de um mercado cada vez mais competitivo, as decisões de onde, como, quando e com o que produzir devem ser tomadas rapidamente. O presente trabalho propõe o desenvolvimento de um método heurístico Beam Search para solucionar o Job Shop Scheduling Problem e o Flexible Job Shop Scheduling Problem. Para isso, inicialmente um algoritmo do tipo list scheduling é definido e então o método Beam Search é construído baseado neste algoritmo. Os métodos propostos foram avaliados em diferentes níveis de complexidade utilizando instâncias da literatura que retratam diferentes cenários de planejamento. Em linhas gerais, as soluções encontradas se mostraram bastante competitivas quando comparadas a outras soluções da literatura. / The Job Shop Scheduling Problem is a NP-Hard problem which draws the attention of researchers due to both its mathematical challenge and its applicability in real contexts. Usually, mainly in industry and factory environments, an optimal schedule got by the use of exact computational methods implies in a long spending time. On the other hand, due to a more and more competitive marketplace, the decisions on where, how, when and with which to produce must be taken quickly. The present work proposes the development of an heuristic Beam Search method to solve both the Job Shop Scheduling Problem and the Flexible Job Shop Scheduling Problem. To that end, at rst a list scheduling algorithm is dened and then the Beam Search method is built based on the list scheduling algorithm. The proposed methods were evaluated over dierent complexity levels using instances from the literature that report dierent planning environments. In general terms, the solutions implemented have been proved very competitive when compared against other solutions in the literature.
