Book excerpt: Ce sujet de thèse concerne de manière générale l'évaluation des performances et l'ordonnancement dans des systèmes de production flexibles et principalement les problèmes d'ordonnancement d'atelier de type Flow-Shop et Flow-Shop hybride. Le problème d'ordonnancement d'un Flow-Shop peut être défini ainsi : un ensemble de N jobs composés chacun de M opérations, doivent passer sur M machines dans le même ordre. Une machine peut exécuter une seule opération à la fois, chaque job ne peut avoir qu'une seule opération en cours de réalisation simultanément et la préemption n'est pas autorisée. Dans le cas des Flow-Shops hybrides, Mk machines identiques sont disponibles à chaque étage k en un ou plusieurs exemplaires. Pour cette étude, notre objectif est toujours de minimiser le temps total d'exécution aussi appelé makespan. Les problèmes d'ordonnancement les plus répandus sont de type Flow-Shop classique où les espaces de stockage entre les machines sont considérées comme infinies. D'autres problèmes sont caractérisés par des capacités de stockage limitées ou nulles qui engendre une seule contrainte de blocage. Cette contrainte peut être un blocage classique (de type RSb) ou particulier (de type RCb ou RCb*). Dans nos travaux de recherche, nous présentons un cas général qui peut être tiré de l'industrie et modélisé sous forme de systèmes de type Flow-Shop et Flow-Shop hybride soumis simultanément à plusieurs types de blocage. Pour résoudre ce genre de problèmes, nous avons étudié dans cette thèse la complexité de ces systèmes et nous avons proposé des méthodes exactes, des méthodes approchées ainsi que des bornes inférieures.

Available in PDF, EPUB and Kindle. Book excerpt: Les travaux de recherche proposés dans cette thèse portent sur les problèmes d'ordonnancement rencontrés dans les systèmes de production automatisés en prenant en compte des contraintes telles que l'absence d'espace de stockage entre les machines et la flexibilité des ressources. Plus particulièrement, nous avons étudié les problèmes d'ordonnancement de job-shops classiques et hybrides soumis à des contraintes de blocage particulières avec comme objectif la minimisation du temps total d'opération. Dans un premier temps, nous avons modélisé les problèmes d'ordonnancement de type job-shop (classique et flexible) avec la contrainte de blocage particulière afin d'obtenir une solution exacte. Pour les problèmes de taille plus importante, il n'était pas possible d'obtenir une solution exacte à ce problème en un temps raisonnable. Par conséquent, nous avons développé des bornes inférieures complémentaires. Dans le cas du job shop classique, une méta-heuristique basée sur l'algorithme de recuit simulé pour résoudre le problème étudié a été proposée. Pour développer un voisinage efficace, nous avons donné une méthode qui permet de détecter les conflits qui peuvent survenir après la modification des séquences. Des résultats d'expérimentations réalisés sur des instances de petites et moyennes tailles montrent l'efficacité de bornes inférieures ainsi que l'heuristique développée
Book Synopsis Ordonnancement Des Systemes Flexibles de Production Sous Contraintes de Disponibilite Des Ressources by : Sadia Azem
Download or read book Ordonnancement Des Systemes Flexibles de Production Sous Contraintes de Disponibilite Des Ressources written by Sadia Azem and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In most of the machine scheduling literature, resources are assumed to be continuously available which is not always true. We deal with the context of unavailability known a priori; we are particularly interested in job-shop scheduling problems with flexible unavailability periods and tasks that can eventually be interrupted by unavailability periods. Integrating these constraints increase the complexity of the scheduling problems. We deal with flexibility that is related to at least one of the following points: moving the unavailability period in a time window, modification of the duration of the unavailability period, interruption of a task by an unavailability period, then resumed with a possible penalty.In this thesis, we propose mathematical models for the problem. In addition to the resolution of the considered problems, the aim of this modeling is to allow for the analysis of the impact of different constraints and evaluation of the quality of the approximate methods and the column generation approach we develop. The approximate methods construct in very short time a schedule based on priority rules. The solutions are also used in our column generation approach. This approach adapts well to various objective functions and allows relatively easily for the integration of several constraints. Many experiments have been performed to validate the designed methods.

Book excerpt: Les travaux de recherche proposés dans cette thèse portent sur l'ordonnancement des systèmes de production de type Flow-Shop, et Flow-Shop hybride à deux étages avec des contraintes de blocage particulières rencontrées dans plusieurs environnements industriels. Dans un premier temps, ces contraintes de blocage ainsi que quelques exemples d'applications sont présentés. Ensuite, la deuxième partie de cette thèse est consacrée aux systèmes de type flow-shop avec blocage. Nous démontrons tout d'abord des résultats de complexité pour ce problème. Ensuite, nous proposons deux modèles mathématiques permettant de résoudre ce problème de façon exacte. Plusieurs bornes inférieures sont ensuite proposées, ainsi que des heuristiques dont la solution est améliorée par un recuit simulé utilisant plusieurs voisinages. La troisième partie concerne les flow-shops hybrides. Nous proposons dans cette partie un modèle mathématique inspiré d'un des modèles mathématiques développés pour le flow-shop avec blocage, plusieurs bornes inférieures, plusieurs heuristiques, dont l'une est une extension de l'heuristique présentée pour le flow-shop, et une adaptation du recuit simulé présenté dans la deuxième partie. Les résultats des expérimentations réalisées sur des jeux de données aléatoires montrent l'efficacité des différents algorithmes proposés.

Available in PDF, EPUB and Kindle. Book excerpt: Mathematical Aspects of Scheduling and Applications addresses the perennial problem of optimal utilization of finite resources in the accomplishment of an assortment of tasks or objectives. The book provides ways to uncover the core of these problems, presents them in mathematical terms, and devises mathematical solutions for them. The book consists of 12 chapters. Chapter 1 deals with network problems, the shortest path problem, and applications to control theory. Chapter 2 stresses the role and use of computers based on the decision-making problems outlined in the preceding chapter. Chapter 3 classifies scheduling problems and their solution approaches. Chapters 4 to 6 discuss machine sequencing problems and techniques. Chapter 5 tackles capacity expansion problems and introduces the technique of embedded state space dynamic programming for reducing dimensionality so that larger problems can be solved. Chapter 6 then examines an important class of network problems with non-serial phase structures and exploits dimensionality reduction techniques, such as the pseudo-stage concept, branch compression, and optimal order elimination methods to solve large-scale, nonlinear network scheduling problems. Chapters 7 to 11 consider the flow-shop scheduling problem under different objectives and constraints. Chapter 12 discusses the job-shop-scheduling problem. The book will be useful to economists, planners, and graduate students in the fields of mathematics, operations research, management science, computer science, and engineering.

Download or read book How to Design Wastewater Systems for Local Conditions in Developing Countries written by David M. Robbins and published by IWA Publishing. This book was released on 2014-03-15 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a practical handbook providing a step-by-step approach to the techniques used for characterizing wastewater sources and investigating sites where collection, treatment and reuse/disposal technologies will be installed. It is intended to help enable local implementation of on-site and decentralized wastewater management system (DWMS)for wide scale use in development settings. How to Design Wastewater Systems for Local Conditions in Developing Countries helps local service providers and regulatory officials make informed decisions through the use of tools, checklists and case studies. It includes a link to a web based community of on-site and decentralized wastewater professionals, which contains related tools and case studies. This handbook serves as a reference for training classes, certification programs, and higher education programs in civil and sanitary engineering. There is an increasing interest on the part of local government officials and private sector service providers to implement wastewater treatment systems to solve sanitation problems. The model presented in this handbook promotes activities that first generate data related to source and site conditions that represent critical inputs, and then applies this information to the technology selection process. Matching the most appropriate technologies to the specific needs of the wastewater project is the key that leads to long term sustainability. How to Design Wastewater Systems for Local Conditions in Developing Countries is an invaluable resource for public sector decision makers and private sector service providers in developing countries. It is also a useful text for students at engineering colleges in developing countries interested in taking a class that teaches the methods of decentralized wastewater management system (DWMS) development.
Book Synopsis Arctic Shipping by : Frédéric Lasserre
Download or read book Arctic Shipping written by Frédéric Lasserre and published by Routledge. This book was released on 2019-09-05 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book considers both the present state of Arctic shipping and possible future trends with reference to the various sectors of maritime transportation: cruise tourism, container traffic and bulk shipping. Ports are analysed as tools that support the strategies of coastal states to foster the development of resource extraction, enhance the attractiveness of Arctic shipping lanes and enable the control of maritime activities through coast guard deployment. The aim of this book is to draw a picture of the trends of Arctic shipping. How is traffic evolving in Canada’s Arctic, or along the Northern Sea Route? Are there significant differences between bulk and container shipping segments when considering the Arctic market? How are the ports and the hinterland developing and what are the strategies behind those? How is the legal framework shaping the evolution of maritime transportation? The contributors to this book consider all of these questions, and more, as they map out the prospects for Arctic shipping and analyse in detail the development of Arctic shipping as a result of multi-variable interactions. This book will be key reading for industry professionals and post-graduate students alike.

Book Synopsis A Zero-one Programming Approach to Scheduling with Limited Resources by : A. Alan B. Pritsker
Download or read book A Zero-one Programming Approach to Scheduling with Limited Resources written by A. Alan B. Pritsker and published by . This book was released on 1968 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: A zero-one linear programming formulation of scheduling problems that is more versatile and efficient than any other known LP formulation. It is the first formulation designed to accommodate multiple resource constraints. Bowman's formulation can be extended to do so, but in a sample comparison, it required 72 variables and 125 constraints for a 3-project, 8-job, 3-resource problem compared with 33 variables and 48 constraints for the new formulation. The new method also showed substantial improvement when compared with schedules based on two common dispatching rules: first-come-first-served and earliest-completion-date. Execution time on an IBM 7044, using the Geoffrion computer code was 3 seconds. Other objective functions are formulated in the study and additional constraints are modeled. Examples of larger problems rewritten for standard LP computer codes showed that the number of variables and constraints involved are probably within no more than one order-of-magnitude of the maximum number that could be handled with available zero-one computer codes.
