This book was released on 1993 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le domaine de ce travail de thèse est l'Ordonnancement de Production. La première partie de ce mémoire traite différents problèmes d'ordonnancement issus d'une application industrielle. La préoccupation de cette problématique industrielle est la réduction des coûts de changements d'outils dans un procédé industriel de fabrication de verre d'emballage. Les deux principales études réalisées portent sur les problèmes d'ordonnancement machines simples et machines parallèles avec coûts de changements dépendants de la séquence. Le premier est équivalent au modèle du Voyageur de Commerce et le deuxième au modèle du Véhicule. Ceux-ci sont des problèmes classiques dans le domaine de l'Optimisation Combinatoire et présentent une nature NP-Complète. Il existe différentes méthodes pour traiter ces problèmes, pouvant être classifiées dans trois groupes : les méthodes exactes, les méthodes de relaxation et les méthodes heuristiques. Parmi les méthodes exactes, citons la Méthode de Séparation & Evaluation et la Méthode de Programmation Dynamique. Les méthodes de relaxation utilisées correspondent à l'Affectation et à l'Arbre de Poids Minimal. Les heuristiques sont celles du 2opt, de la Plus Proche Ville et de l'Arbre de Poids Minimal. Les algorithmes ont tout d'abord été utilisés dans le cas de machines simples et ensuite adaptés au cas de machines parallèles. Les machines parallèles utilisent d'autres méthodes de résolution spécifiques pour le modèle du Véhicule, en particulier une heuristique basée sur la Méthode Deux-Phases. La deuxième partie du travail concerne la conception et la validation d'un système nommé «Atelier Logiciel d'Ordonnancement». Celui-ci comprend une structure d'accueil pour différentes classes d'algorithmes d'ordonnancement, comme par exemple les problèmes décrits ci-dessous, et d'autres comme le job-shop et l'affectation de tâches aux machines.

This book was released on 1990 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: cette thèse, qui s'est déroulée dans le cadre d'une recherche industrielle appliquée a la production des bouteilles en verre, s'intéresse plus généralement à la programmation des changements de fabrication dans un système de gestion de production semi-continue. Un premier chapitre situe le problème général de la gestion de production, puis celui plus restreint de l'ordonnancement en citant les modélisations et les principaux outils développés dans ce domaine. Le champ des investigations est ensuite limite aux seules industries de process a productions semi-continues. Le chapitre 2 présente le cas d'application détaille de l'étude. Le troisième chapitre permet d'établir un lien entre les approches conceptuelles appliquées aux systèmes réels complexes systèmes hiérarchises, intégration multi-outil, aide a la décision et le cas d'application. après quoi est isolé le problème central de minimisation des coûts de changement combinés au respect des délais. Le chapitre 4 est consacre a la résolution du problème évoqué, à l'aide d'un outil simple et d'une méthode originale de pénalisation. Le dernier chapitre propose l'esquisse des autres modules d'un système complet d'ordonnancement décentralisé, avec la description des différents modules proposés, l'architecture et l'interface ayant déjà été implémentée

Download or read book Recent Advances in Global Optimization written by Christodoulos A. Floudas and published by Princeton University Press. This book was released on 2014-07-14 with total page 644 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will present the papers delivered at the first U.S. conference devoted exclusively to global optimization and will thus provide valuable insights into the significant research on the topic that has been emerging during recent years. Held at Princeton University in May 1991, the conference brought together an interdisciplinary group of the most active developers of algorithms for global optimization in order to focus the attention of the mathematical programming community on the unsolved problems and diverse applications of this field. The main subjects addressed at the conference were advances in deterministic and stochastic methods for global optimization, parallel algorithms for global optimization problems, and applications of global optimization. Although global optimization is primarily a mathematical problem, it is relevant to several other disciplines, including computer science, applied mathematics, physical chemistry, molecular biology, statistics, physics, engineering, operations research, communication theory, and economics. Global optimization problems originate from a wide variety of mathematical models of real-world systems. Some of its applications are allocation and location problems and VLSI and data-base design problems. Originally published in 1991. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
Download or read book Managing Interdisciplinary Projects written by Stephen Emmitt and published by Routledge. This book was released on 2010-04-26 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Construction, architecture and engineering projects are complex undertakings, involving a temporary grouping of people and companies, with different agendas and experience, coming together to achieve a project goal. This book investigates the dynamics of the relationships between individuals involved in architecture, engineering and construction projects. It combines a structured theoretical framework, derived from social psychology and mainstream management theory, with case studies and research from the built environment sector. Focusing on how people interact, communicate and work together, it examines how best to manage the interdisciplinary relationships that form and reform during the project life cycle. The book covers vital areas of project management, whose importance has recently come to be recognized, and will be valuable for students at both undergraduate and graduate level. Practitioners will also find it a useful insight into the social aspect of project management, with implications and applications that apply to all projects in the built environment sector.

Download or read book Essays and Surveys in Global Optimization written by Charles Audet and published by Springer Science & Business Media. This book was released on 2005-12-05 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global optimization aims at solving the most general problems of deterministic mathematical programming: to find the global optimum of a nonlinear, nonconvex, multivariate function of continuous and/or integer variables subject to constraints which may be themselves nonlinear and nonconvex. In addition, once the solutions are found, proof of its optimality is also expected from this methodology. Therefore, with these difficulties in mind, global optimization is becoming an increasingly powerful and important methodology. Essays and Surveys in Global Optimization is the most recent examination of its mathematical capability, power, and wide ranging solutions to many fields in the applied sciences.

Available in PDF, EPUB and Kindle. Book excerpt: The evolution of broadband access networks toward bimodal fiber-wireless (FiWi) access networks, described in this book, may be viewed as the endgame of broadband access. After discussing the economic impact of broadband access and current worldwide deployment statistics, all the major legacy wireline and wireless broadband access technologies are reviewed. State-of-the-art GPON and EPON fiber access networks are described, including their migration to next-generation systems such as OCDMA and OFDMA PONs. The latest developments of wireless access networks are covered, including VHT WLAN, Gigabit WiMAX, LTE and WMN. The advantages of FiWi access networks are demonstrated by applying powerful network coding, heterogeneous optical and wireless protection, hierarchical frame aggregation, hybrid routing and QoS continuity techniques across the optical-wireless interface. The book is an essential reference for anyone working on optical fiber access networks, wireless access networks or converged FiWi systems.

Download or read book Adaptive Stream Mining written by Albert Bifet and published by IOS Press. This book was released on 2010 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a significant contribution to the subject of mining time-changing data streams and addresses the design of learning algorithms for this purpose. It introduces new contributions on several different aspects of the problem, identifying research opportunities and increasing the scope for applications. It also includes an in-depth study of stream mining and a theoretical analysis of proposed methods and algorithms. The first section is concerned with the use of an adaptive sliding window algorithm (ADWIN). Since this has rigorous performance guarantees, using it in place of counters or accumulators, it offers the possibility of extending such guarantees to learning and mining algorithms not initially designed for drifting data. Testing with several methods, including Naïve Bayes, clustering, decision trees and ensemble methods, is discussed as well. The second part of the book describes a formal study of connected acyclic graphs, or 'trees', from the point of view of closure-based mining, presenting efficient algorithms for subtree testing and for mining ordered and unordered frequent closed trees. Lastly, a general methodology to identify closed patterns in a data stream is outlined. This is applied to develop an incremental method, a sliding-window based method, and a method that mines closed trees adaptively from data streams. These are used to introduce classification methods for tree data streams.
