Book excerpt: Esta dissertação investiga a aplicação de Algoritmos Genéticos e de Co-Evolução Cooperativa na otimização da programação da produção em refinarias de petróleo. Refinarias de petróleo constituem um dos mais importantesexemplos de plantas contínuas multiproduto, isto é, um sistema de processamento contínuo gerador de múltiplos produtos simultâneos. Uma refinaria, em geral, processa um ou mais tipos de petróleo, produzindo uma série de produtos derivados, como o GLP (gás liquefeito de petróleo), a nafta, o querosene e o óleo diesel. Trata-se de um problema complexo de otimização, devido ao número e diversidade de atividades existentes e diferentes objetivos. Além disso, neste problema, algumas atividades dependem de que outras atividades já tenham sido planejadas para que possam então ser planejadas. Um caso típico é o das retiradas de produtos de uma unidade de processo, que dependem de que a carga já tenha sido planejada, assim como em qual campanha a unidade estará naquele instante. Por isso, o uso de modelos revolucionários convencionais, como os baseados em ordem, pode gerar muitas soluções inválidas, que deverão ser posteriormente corrigidas ou descartadas, comprometendo o desempenho e a viabilidade do algoritmo. O objetivo dotrabalho foi, então, desenvolver um modelo evolucionário para otimizar a programação da produção (scheduling), segundo objetivos bem definidos, capaz de lidar com as restrições do problema, gerando apenas soluções viáveis. O trabalho consistiu em três etapas principais: um estudo sobre o refino de petróleo e a programação da produção em refinarias; a definição de um modelo usando algoritmos genéticos e co-evolução cooperativa para otimização da programação da produção e a implementação de uma ferramenta para estudo de caso. O estudo sobre o refino e a programação da produção envolveu o levantamento das várias etapas do processamento do petróleo em uma refinaria, desde o seu recebimento, destilação e transformação em diversos produtos acabados, que são então enviados a seus respectivos destinos. Neste estudo, também foi levantada a estrutura de tomada de decisão em uma refinaria e seus vários níveis, diferenciando os objetivos destes níveis e explicitando o papel da programação da produção nesta estrutura. A partir daí, foram estudadas emdetalhes todas as atividades que normalmente ocorrem na refinaria e que são definidas na programação, e seus papéis na produção da refinaria. A decisão de quando e com que recursos executar estas atividades é o resultado final da programação e, portanto, a saída principal do algoritmo. A modelagem do algoritmo genético consistiu inicialmente em um estudo de representações utilizadas para problemas de scheduling. O modelo coevolucionário adotado considera a decomposição do problema em duas partes e, portanto, emprega duas populações com responsabilidades diferentes: uma é responsável por indicar quando uma atividade deve ser planejada e a outra é responsável por indicar com quais recursos essa mesma atividade deve ser realizada. A primeira população teve sua representação baseada em um modelo usado para problemas do tipo Dial-A-Ride (Moon et al, 2002), que utiliza um grafo para indicar à função de avaliação a ordem na qual o planejamento deve ser construído. Esta representação foi elaborada desta forma para que fosse levada em conta a existência de restrições de precedência (atividades que devem ser planejadas antes de outras), e assim não fossem geradas soluções inválidas pelo algoritmo. A segunda população, que se responsabiliza pela alocação dos recursos para a execução das atividades, conta com uma representação onde os operadores genéticos podem atuar na ordem de escolha dos recursos que podem realizar cada uma das atividades. Finalmente, desenvolveu-se uma ferramenta para implementar estes modelos e tratar de um estudo de caso, que oferecesse as característicasnecessárias para testar a qualidade das representações e avaliar os resultados. Foi criada uma refinaria bem simples, mas que contasse com todos os tipos de equipamentos, atividades e restrições presentes em uma refinaria real. As restrições existentes são tanto as de precedência, que são incorporadas através do grafo utilizado pela primeira espécie, quanto às restrições operacionais inerentes ao problema e à planta escolhida. Com isso, foi possível validar o processo de decodificação dos cromossomos em soluções viáveis, respeitando as restrições do problema. Foram realizados vários testes que demonstraram a capacidad e dos modelos desenvolvidos em gerar soluções viáveis, sem a necessidade de heurísticas de correção, e os resultados obtidos foram comparados com os de um processo de busca exaustiva. Foram criados três cenários de teste com demandas, restrições e tamanhosdiferentes. Em todos os casos, os resultados obtidos pelos modelos foram sempre muito superiores aos da busca exaustiva.

Book excerpt: Esta dissertação investiga o uso de Algoritmos Genéticos e de Co-Evolução Cooperativa na otimização de problemas de planejamento com restrições de precedência. Neste tipo de problema algumas ou todas as tarefas têm restrições que implicam na necessidade de planejá-las ou executá-las antes ou depois de outras. Por esta razão, o uso de modelos evolucionários convencionais como, por exemplo, os baseados em ordem pode gerar soluções inválidas, não penalizáveis, que precisam ser descartadas, comprometendo assim o desempenho do algoritmo. O objetivo do trabalho foi, portanto, estudar formas de representação de soluções para este tipo de problema capazes de gerar somente soluções válidas, bem como avaliar o desempenho dos modelos propostos. O trabalho consistiu de 3 etapas principais: um estudo sobre problemas de otimização de planejamento com algoritmos genéticos; a definição de novos modelos usando algoritmos genéticos e co-evolução cooperativa para otimização de problemas de planejamento com restrições de precedência e a implementação de uma ferramenta para estudo de caso. O estudo sobre os problemas de otimização de planejamentos com algoritmos genéticos envolveu o levantamento de representações, dificuldades e características deste tipo de problema e, mais especificamente, de representaçõesbaseadas em ordem. A modelagem do algoritmo genético consistiu fundamentalmente na definição de uma representação dos cromossomas e da função da avaliação que levasse em conta a existência de restrições de precedência (tarefas que devem ser planejadas/executadas antes de outras).A construção do modelo co-evolucionário por sua vez consistiu em definir uma nova população, com uma outra representação, que se responsabilizasse pela distribuição dos recursos para execução das tarefas, responsabilidade esta que, no modelo com algoritmos genéticos convencionais, era tratada de forma simples por um conjunto de heurísticas. Finalmente, desenvolveu-se uma ferramenta para implementar estes modelos e tratar de um estudo de caso complexo que oferecesse as características necessárias para testar a qualidade das representações e avaliar os resultados. Oestudo de caso escolhido foi a otimização do planejamento da descarga, armazenamento e embarque de minério de ferro de modo a minimizar o tempo de estadia dos navios em um porto fictício. Foram realizados vários testes que demonstraram a capacidade dos modelos desenvolvidos em gerar soluções viáveis, sem a necessidade de heurísticas de correção, e os resultados obtidos foram comparados com os de um processo de busca aleatória. Em todos os casos, os resultados obtidos pelos modelos foram sempre superiores aos obtidos pela busca aleatória. No caso do modelo de representação com uma única população obteve-se resultados até 41%melhores do que com os obtidos por uma busca aleatória. No caso do modelo de representação com co-evolução o resultado ficou 33% melhor que a busca aleatória com tratamento de solução idêntico ao da solução co-evolucionária. Osresultados da co-evolução comparados com o algoritmo genético com uma única espécie foram 29% melhores.

Available in PDF, EPUB and Kindle. Book excerpt: This book introduces readers to an evolutionary learning approach, specifically genetic programming (GP), for production scheduling. The book is divided into six parts. In Part I, it provides an introduction to production scheduling, existing solution methods, and the GP approach to production scheduling. Characteristics of production environments, problem formulations, an abstract GP framework for production scheduling, and evaluation criteria are also presented. Part II shows various ways that GP can be employed to solve static production scheduling problems and their connections with conventional operation research methods. In turn, Part III shows how to design GP algorithms for dynamic production scheduling problems and describes advanced techniques for enhancing GP’s performance, including feature selection, surrogate modeling, and specialized genetic operators. In Part IV, the book addresses how to use heuristics to deal with multiple, potentially conflicting objectives in production scheduling problems, and presents an advanced multi-objective approach with cooperative coevolution techniques or multi-tree representations. Part V demonstrates how to use multitask learning techniques in the hyper-heuristics space for production scheduling. It also shows how surrogate techniques and assisted task selection strategies can benefit multitask learning with GP for learning heuristics in the context of production scheduling. Part VI rounds out the text with an outlook on the future. Given its scope, the book benefits scientists, engineers, researchers, practitioners, postgraduates, and undergraduates in the areas of machine learning, artificial intelligence, evolutionary computation, operations research, and industrial engineering.

Book excerpt: O objetivo desta dissertação é desenvolver um método de solução baseado em Algoritmos Genéticos (GAs) aliado a um Sistema Baseado em Regras para encontrar e otimizar as soluções geradas para o problema de programação da produção de Óleos Combustíveis e Asfalto na REVAP (Refinaria do Vale do Paraíba). A refinaria é uma planta multiproduto, com dois estágios de máquinas em série um misturador e umconjunto de tanques, com restrição de recursos e operando em regime contínuo. Foram desenvolvidos neste trabalho dois modelos baseados em algoritmos genéticos que são utilizados para encontrar a seqüência e os tamanhos dos lotes deprodução dos produtos finais. O primeiro modelo proposto utiliza uma representação direta da programação da produção em que o horizonte de programação é dividido em intervalos discretos de um hora. O segundo modelo proposto utiliza uma representação indireta que é decodificada para formar a programação da produção. O Sistema Baseado em Regras é utilizado na escolha dos tanques que recebem a produção e ostanques que atendem à demanda dos diversos centros consumidores existentes. Um novo operador de mutação Mutação por Vizinhança foi proposto para minimizar o número de trocas operacionais na produção. Uma técnica para agregação de múltiplos objetivos, baseado no Método de Minimização de Energia, também foi incorporado aos Algoritmos Genéticos. Os resultados obtidos confirmam que os Algoritmos Genéticos propostos, associados com o Método de Minimização de Energia e a Mutação por Vizinhança, sãocapazes de resolver o problema de programação da produção, otimizando os objetivos operacionais da refinaria.

This book was released on 1999-08-31 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiobjective Scheduling by Genetic Algorithms describes methods for developing multiobjective solutions to common production scheduling equations modeling in the literature as flowshops, job shops and open shops. The methodology is metaheuristic, one inspired by how nature has evolved a multitude of coexisting species of living beings on earth. Multiobjective flowshops, job shops and open shops are each highly relevant models in manufacturing, classroom scheduling or automotive assembly, yet for want of sound methods they have remained almost untouched to date. This text shows how methods such as Elitist Nondominated Sorting Genetic Algorithm (ENGA) can find a bevy of Pareto optimal solutions for them. Also it accents the value of hybridizing Gas with both solution-generating and solution-improvement methods. It envisions fundamental research into such methods, greatly strengthening the growing reach of metaheuristic methods. This book is therefore intended for students of industrial engineering, operations research, operations management and computer science, as well as practitioners. It may also assist in the development of efficient shop management software tools for schedulers and production planners who face multiple planning and operating objectives as a matter of course.

Book excerpt: Production scheduling dictates highly constrained mathematical models with complex and often contradicting objectives. Evolutionary algorithms can be formulated almost independently of the detailed shaping of the problems under consideration. As one would expect, a weak formulation of the problem in the algorithm comes along with a quite inefficient search. This book discusses the suitability of genetic algorithms for production scheduling and presents an approach which produces results comparable with those of more tailored optimization techniques.

This book was released on 2012-12-06 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the introduction of genetic algorithms in the 1970s, an enormous number of articles together with several significant monographs and books have been published on this methodology. As a result, genetic algorithms have made a major contribution to optimization, adaptation, and learning in a wide variety of unexpected fields. Over the years, many excellent books in genetic algorithm optimization have been published; however, they focus mainly on single-objective discrete or other hard optimization problems under certainty. There appears to be no book that is designed to present genetic algorithms for solving not only single-objective but also fuzzy and multiobjective optimization problems in a unified way. Genetic Algorithms And Fuzzy Multiobjective Optimization introduces the latest advances in the field of genetic algorithm optimization for 0-1 programming, integer programming, nonconvex programming, and job-shop scheduling problems under multiobjectiveness and fuzziness. In addition, the book treats a wide range of actual real world applications. The theoretical material and applications place special stress on interactive decision-making aspects of fuzzy multiobjective optimization for human-centered systems in most realistic situations when dealing with fuzziness. The intended readers of this book are senior undergraduate students, graduate students, researchers, and practitioners in the fields of operations research, computer science, industrial engineering, management science, systems engineering, and other engineering disciplines that deal with the subjects of multiobjective programming for discrete or other hard optimization problems under fuzziness. Real world research applications are used throughout the book to illustrate the presentation. These applications are drawn from complex problems. Examples include flexible scheduling in a machine center, operation planning of district heating and cooling plants, and coal purchase planning in an actual electric power plant.

Available in PDF, EPUB and Kindle. Book excerpt: OmeGA: A Competent Genetic Algorithm for Solving Permutation and Scheduling Problems addresses two increasingly important areas in GA implementation and practice. OmeGA, or the ordering messy genetic algorithm, combines some of the latest in competent GA technology to solve scheduling and other permutation problems. Competent GAs are those designed for principled solutions of hard problems, quickly, reliably, and accurately. Permutation and scheduling problems are difficult combinatorial optimization problems with commercial import across a variety of industries. This book approaches both subjects systematically and clearly. The first part of the book presents the clearest description of messy GAs written to date along with an innovative adaptation of the method to ordering problems. The second part of the book investigates the algorithm on boundedly difficult test functions, showing principled scale up as problems become harder and longer. Finally, the book applies the algorithm to a test function drawn from the literature of scheduling.
