Book Integer Programming and Related Areas

Download or read book Integer Programming and Related Areas written by C. Kastning and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integer Prograw~ing is one of the most fascinating and difficult areas in the field of Mathematical Optimization. Due to this fact notable research contributions to Integer Programming have been made in very different branches of mathematics and its applications. Since these publications are scattered over many journals, proceedings volumes, monographs, and working papers, a comprehensive bibliography of all these sources is a helpful tool even for specialists in this field. I initiated this compilation of literature in 1970 at the Institut fur ~konometrie und Operations Research, University of Bonn. Since then many collaborators have contributed to and worked on it. Among them Dipl.-Math. Claus Kastning has done the bulk of the work. With great perseverance and diligence he has gathered all the material and checked it with the original sources. The main aim was to incorporate rare and not easily accessible sources like Russian journals, preprints or unpublished papers. Without the invaluable and dedicated engagement of Claus Kastning the bibliography would never have reached this final version. For this reason he must be considered its responsible editor. As with any other collection this literature list has a subjective viewpoint and may be in some sense incomplete. We have however tried to be as complete as possible. The bibliography contains 4704 different publications by 6767 authors which were classified by 11839 descriptor entries.

Book R solution exacte de probl mes d ordonnancement de type flowshop de permutation en pr sence de contraintes d carts temporels entre op rations

Download or read book R solution exacte de probl mes d ordonnancement de type flowshop de permutation en pr sence de contraintes d carts temporels entre op rations written by Julien Fondrevelle and published by . This book was released on 2005 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans ce mémoire, nous nous intéressons à l'étude et la résolution de problèmes d'ordonnancement de type flowshop de permutation, en présence de contraintes d'écarts temporels (ou time lags), définies entre les couples d'opérations consécutives au sein des travaux. De telles contraintes généralisent les contraintes de précédence classiques et peuvent modéliser de nombreuses situations réelles. De nouveaux résultats de complexité sont démontrés et viennent compléter des résultats classiques tirés de la littérature. Nous présentons aussi un état de l'art assez détaillé sur les travaux concernant les problèmes d'ordonnancement avec time lags, qui met en évidence le manque d'attention reçu par ces problèmes. Nous développons ensuite un schéma générique de résolution exacte reposant sur une Procédure par Séparation et Evaluation et nous l'utilisons pour résoudre plusieurs problèmes de flowshop de permutation en présence de time lags. L'efficacité de cette approche de résolution est évaluée grâce à des séries d'expériences numériques. Enfin, des extensions permettant de prendre en compte des contraintes supplémentaires sont proposées.

Book Complexit et algorithmes pour l ordonnancement multicrit re des travaux ind pendants

Download or read book Complexit et algorithmes pour l ordonnancement multicrit re des travaux ind pendants written by Nguyen Huynh Tuong and published by . This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nous abordons dans cette thèse deux types de problèmes d'ordonnancement sur une machine ou sur des machines parallèles : 1. les problèmes d'ordonnancement de type juste-à-temps : il s'agit de déterminer un ordonnancement de sorte que les travaux se terminent le plus près possible de leur date de fin souhaitée. On considère le cas où la date de fin souhaitée commune est connue et le cas où elle est à déterminer. De nouveaux algorithmes exacts sont proposés. Des schémas d'approximation sont élaborés. 2. les problèmes d'ordonnancements de travaux interférants : il s'agit de déterminer un ordonnancement qui permet d'optimiser un critère pour tous les travaux, sachant que la solution trouvée doit permettre également l'optimisation d'un autre critère défini uniquement sur un sous-ensemble des travaux. Il s'agit ici d'un nouveau problème d'ordonnancement multicritère, différent de la notion classique. Les approches considérées pour trouver une solution non dominée sont l'approche e-contrainte, la combinaison linéaire de critères et le goal programming. De nouveaux résultats de complexité sont montrés et des algorithmes exacts sont développés.

Book Probl mes d ordonnancement

Download or read book Probl mes d ordonnancement written by Jacques Carlier and published by . This book was released on 2009 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work deals with a project scheduling problem where the units of resources are produced or consumed at the occurrence of precedence-related events. We have presented a model which takes account of the production and consumption of resources. We have reported some complexity results related to the problem and have proposed several arbitrage algorithms which permit us to build the earliest schedule associated with a complete or consumption arbitrage. These algorithms may be also helpful to solve exactly or heuristically the project scheduling problem with production and consumption of resources. We have proposed a memetic algorithm for solving the resource constrained project scheduling problem (RCPSP), which is a special case of the problem above. Computational experiments were run on a standard set of 1560 instances. The results show that our algorithm is competitive with the best known algorithms. We have also proposed a branch-and-bound method to solve the problem optimally. In order to improve the computational time, we have adapted the JPPS lower bound to our problem with a relaxation to RCPSP, and the shift algorithm with a relaxation to problems with non-renewable resources.

Available in PDF, EPUB and Kindle. Book excerpt: Les travaux de recherche propôsés dans cette thèse portent essentiellement sur les problèmes d'ordonnancement rencontrés dans les systèmes de production automatisés et tiennent compte de nouvelles containtes, notamment la prise en compte des moyens de transport, des stocks tampons de capacité limitée, de la flexibilité de ressources, etc. Trois objectifs principaux sont fixés, à savoir la proposition de nouveaux modèles d'ordonnancement, l'étude de la complexité de ces problèmes et enfin le développement d'approches intégrées pour l'ordonnancement et le contrôle des systèmes étudiés. Plus précisément, nous développons des modèles d'ordonnancement permettant d'incorporer les différentes caractéristiques des systèmes de production automatisés. De nouveaux résultats de complexité sont représentés et des algorithmes polynomiaux sont proposés pour des cas de nos modèles.

Book Ant Colony Optimization

Download or read book Ant Colony Optimization written by Marco Dorigo and published by MIT Press. This book was released on 2004-06-04 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: An overview of the rapidly growing field of ant colony optimization that describes theoretical findings, the major algorithms, and current applications. The complex social behaviors of ants have been much studied by science, and computer scientists are now finding that these behavior patterns can provide models for solving difficult combinatorial optimization problems. The attempt to develop algorithms inspired by one aspect of ant behavior, the ability to find what computer scientists would call shortest paths, has become the field of ant colony optimization (ACO), the most successful and widely recognized algorithmic technique based on ant behavior. This book presents an overview of this rapidly growing field, from its theoretical inception to practical applications, including descriptions of many available ACO algorithms and their uses. The book first describes the translation of observed ant behavior into working optimization algorithms. The ant colony metaheuristic is then introduced and viewed in the general context of combinatorial optimization. This is followed by a detailed description and guide to all major ACO algorithms and a report on current theoretical findings. The book surveys ACO applications now in use, including routing, assignment, scheduling, subset, machine learning, and bioinformatics problems. AntNet, an ACO algorithm designed for the network routing problem, is described in detail. The authors conclude by summarizing the progress in the field and outlining future research directions. Each chapter ends with bibliographic material, bullet points setting out important ideas covered in the chapter, and exercises. Ant Colony Optimization will be of interest to academic and industry researchers, graduate students, and practitioners who wish to learn how to implement ACO algorithms.

Book Handbook of Constraint Programming

Download or read book Handbook of Constraint Programming written by Francesca Rossi and published by Elsevier. This book was released on 2006-08-18 with total page 977 pages. Available in PDF, EPUB and Kindle. Book excerpt: Constraint programming is a powerful paradigm for solving combinatorial search problems that draws on a wide range of techniques from artificial intelligence, computer science, databases, programming languages, and operations research. Constraint programming is currently applied with success to many domains, such as scheduling, planning, vehicle routing, configuration, networks, and bioinformatics.The aim of this handbook is to capture the full breadth and depth of the constraint programming field and to be encyclopedic in its scope and coverage. While there are several excellent books on constraint programming, such books necessarily focus on the main notions and techniques and cannot cover also extensions, applications, and languages. The handbook gives a reasonably complete coverage of all these lines of work, based on constraint programming, so that a reader can have a rather precise idea of the whole field and its potential. Of course each line of work is dealt with in a survey-like style, where some details may be neglected in favor of coverage. However, the extensive bibliography of each chapter will help the interested readers to find suitable sources for the missing details. Each chapter of the handbook is intended to be a self-contained survey of a topic, and is written by one or more authors who are leading researchers in the area.The intended audience of the handbook is researchers, graduate students, higher-year undergraduates and practitioners who wish to learn about the state-of-the-art in constraint programming. No prior knowledge about the field is necessary to be able to read the chapters and gather useful knowledge. Researchers from other fields should find in this handbook an effective way to learn about constraint programming and to possibly use some of the constraint programming concepts and techniques in their work, thus providing a means for a fruitful cross-fertilization among different research areas.The handbook is organized in two parts. The first part covers the basic foundations of constraint programming, including the history, the notion of constraint propagation, basic search methods, global constraints, tractability and computational complexity, and important issues in modeling a problem as a constraint problem. The second part covers constraint languages and solver, several useful extensions to the basic framework (such as interval constraints, structured domains, and distributed CSPs), and successful application areas for constraint programming.- Covers the whole field of constraint programming- Survey-style chapters- Five chapters on applications
