Available in PDF, EPUB and Kindle. Book excerpt: Les entreprises sont soumises à un environnement concurrentiel accru les poussant à être de plus en plus performantes. La satisfaction des délais clients reste aujourd'hui un enjeu majeur qui définit en partie la compétitivité d'une entreprise. Dans ce contexte, l'activité d'ordonnancement jour un rôle crucial dans le respect des délais clients. Dans la plupart des travaux traitant des problèmes d'rdonnancement d'atelier, les critères de performance des ordonnancements sont associés aux tâches individuelles. Ce critère n'est paspertinent lorsqu'il s'agit d'ordonnancer des commandes clients composées de plusieurs tâches. En effet, une commande est à l’heure lorsque toutes ses tâches le sont. Nous étudions la complexité de quelques problèmes d'ordonnancement de commande sur une machine. Nous nous sommes ensuite intéressés particulièrement à deux types de problèmes: la minimisation du nombre pondéré de commandes en retard sur une machine avec contrainte de disponibilité des tâches et la minimisation du retard pondéré des commandes dans un atelier du type job shop. Ces deux problèmes sont NP-difficiles. Pour résoudre ces deux problèmes, nous développons des méthodes approchées. Pour le premier, une méthode de relaxation lagrangienne est développée. Pour le second, nous proposons des heuristiques de liste utilisant des règles de priorité basées sur les commandes. Nous développons plusieurs méthodes de recherche locale. Une analyse expérimentale montre qu’une recherche taboue probabiliste donne de bons résultats en un temps très faible. Un algorithme génétique hybride permet de trouver les meilleurs résultats pour un certain nombre d’instances en un temps raisonnable.

This book was released on 2013-05-01 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pour assurer une production de biens de qualité, de manière fiable et dans des délais maîtrisés, les organisations ont besoin d’outils d'exécution optimale de tâches tels que l’ordonnancement. Le succès des méthodologies de résolution des problèmes d’ordonnancement de production basées sur les métaheuristiques s’explique par leur capacité à fournir des solutions proches de l’optimum, dans des temps raisonnables. Cet ouvrage se consacre, dans un premier temps, aux métaheuristiques appliquées aux problèmes d’ordonnancement multicritère, qui sont des cas particuliers des problèmes d’optimisation combinatoire multicritère, généralement NP-difficiles. Puis, il s’intéresse aux préoccupations d’ordonnancement dans le secteur du transport qui suscitent également de multiples problèmes d’optimisation. Deux grands domaines d’application se distinguent, celui des systèmes de transport et celui des ressources de transport intervenant dans un atelier.

Available in PDF, EPUB and Kindle. Book excerpt: Understanding how to make the best of human skills and knowledge is essential in the design of technology and jobs, particularly where these involve decision-making and uncertainty. Recent developments have been made in naturalistic decision-making, distributed cognition and situational awareness, particularly with respect to aviation, transport and strategic planning, the nuclear industry and other high-risk industries. Despite the integration of computer-based support systems in production scheduling in recent years, the reality is that most enterprises consist of reactive re-scheduling, involving a high degree of human involvement. It is often with the insight, knowledge and skills of people that scheduling skills can function with any degree of success. Human Performance in Planning and Scheduling covers many industries, including clothing, steel, machine tools, paper/board, and the automobile industry. Using international case studies from various manufacturing industries, they highlight the fact that the human scheduler is a pivotal element in the scheduling process. Each section of the book includes an introduction with an overview of the material to follow, clearly identifying themes, discussion points and highlights inter-connections between the authors' work.

Download or read book Supply Chain Scheduling written by Zhi-Long Chen and published by Springer Nature. This book was released on 2022-02-07 with total page 699 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supply chain scheduling is a relatively new research area with less than 20 years of history. It is an intersection of two traditional areas: supply chain management and scheduling. In this book, the authors provide a comprehensive coverage of supply chain scheduling. The book covers applications, solution algorithms for solving related problems, evaluation of supply chain conflicts, and models for encouraging cooperation between decision makers. Supply chain scheduling studies detailed scheduling issues within supply chains, as motivated by a variety of applications in the real world. Topics covered by the book include: Coordinated decision making in centralized supply chains, including integrated production and distribution scheduling, joint scheduling and product pricing, and coordinated subcontracting and scheduling. Coordination and competition issues in decentralized supply chains, including conflict and cooperation within scheduling decisions made by different parties in supply chains, and both cooperative and non-cooperative supply chain scheduling games. The book describes a variety of representative problems within each of these topics. The authors define these problems mathematically, describe corresponding applications, and introduce solution methods for solving each problem to improve supply chain performance.
