Book excerpt: Le travail présenté dans cette thèse constitue une contribution à la simplification et à la commande des réseaux de Petri stochastiques, utilisés pour la modélisation et l'étude des systèmes de production. Dans le contexte industriel actuel ou l'étude des systèmes manufacturiers s'avère de plus en plus complexe, nous apportons une méthode de réducation de modèles stochastiques, conduisans à une diminution du temps d'obtention des performances des systèmes. Les travaux se résument en deux grands points : Tout d'abord, une méthode de simplification graphique et analytique des réseaux de Petri stochastiques a été développée. Elle effectue un découplage du RDPS suivant les dynamiques des probabilités de marquage, et utilise les techniques de perturbations singulières en continu et en discret. En résultat, nous obtenons deux sous-systèmes aux évolutions lentes ou rapides et aux dimensions réduites facilitant ainsi leur analyse. Utilisant la propriété des processus de markov de la partie lente, une technique de construction du RDPS lent a été développée. La simplification est alors graphique pour le RDPS et analytique pour le processus de Markov. Ensuite, nous avont étendu cette méthode de simplification aux RDPS à commande avec une application à la recherche de la commande optimale.
Book Synopsis Optimization of Logistics by : Alice Yalaoui
Download or read book Optimization of Logistics written by Alice Yalaoui and published by John Wiley & Sons. This book was released on 2012-12-13 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to help engineers, Masters students and young researchers to understand and gain a general knowledge of logistic systems optimization problems and techniques, such as system design, layout, stock management, quality management, lot-sizing or scheduling. It summarizes the evaluation and optimization methods used to solve the most frequent problems. In particular, the authors also emphasize some recent and interesting scientific developments, as well as presenting some industrial applications and some solved instances from real-life cases. Performance evaluation tools (Petri nets, the Markov process, discrete event simulation, etc.) and optimization techniques (branch-and-bound, dynamic programming, genetic algorithms, ant colony optimization, etc.) are presented first. Then, new optimization methods are presented to solve systems design problems, layout problems and buffer-sizing optimization. Forecasting methods, inventory optimization, packing problems, lot-sizing quality management and scheduling are presented with examples in the final chapters.

Book Synopsis Réseaux de Petri stochastiques à forme produit by : Hoang-Thach Nguyen
Download or read book Réseaux de Petri stochastiques à forme produit written by Hoang-Thach Nguyen and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'objectif de cette thèse est de caractériser et d'analyser les réseaux de Pétri stochastiques ayant une distribution stationnaire à forme produit. La première contribution est la caractérisation d'une classe de réseaux de Pétri à forme produit. On introduit la classe des Π2-nets pour lesquels une distribution stationnaire à forme produit existe pour tous les taux de transition, Ensuite, on montre que l'intersection de la classe des Π2-nets et de la classe des réseaux de Pétri à choix libres est une classe classique des réseaux de files d'attente à forme produit : les réseaux de Jackson. La deuxième contribution consiste en deux méthodes effectives pour créer des Π2-nets. La première méthode consiste à générer un Π2-net à partir du réseau vide en utilisant un ensemble de règles de synthèse. La deuxième méthode revient à ajouter des contraintes à un réseau existant afin de le transformer en un Π2-net. La troisième contribution est une caractérisation de la classe des Π2-nets en terme de complexité. On montre que les problèmes d'accessiblité et de vivacité pour les Π2-nets 1-bornés sont PSPACE-complets. Cependant, le problème de couverture pour les Π2-nets généraux est EXPSPACE-complet. La dernière contribution est l'introduction de la sous-classe des Π3-nets, pour lesquels la constante de normalisation peut être calculée efficacement par la programmation dynamique.

Book Synopsis Organizing Smart Buildings and Cities by : Elisabetta Magnaghi
Download or read book Organizing Smart Buildings and Cities written by Elisabetta Magnaghi and published by Springer Nature. This book was released on 2021-02-01 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United Nations included sustainable cities and communities in its 2030 SDGs. Cities and, on a smaller scale, neighborhoods, building managers and firms are now adopting technologies and information systems to help achieve the energy, economic, social and environmental transition. This volume gathers contributions on the key organizational success factors for this transition. To do so, it analyzes the role of information systems, use of data, and technological assistance solutions from multiple perspectives. The goal is to develop a framework that can successfully apply information systems to organizational and environmental issues for smart cities and smart buildings. Accordingly, the book addresses living-lab experiment evaluation techniques, and provides critical analyses of the role of the environment, context and users’ behavioral responses. In addition, it discusses key questions on the efficient management of resources, need for appropriate IT solutions, and employing co-creation with users to improve planning and organization.

Book Synopsis The Palgrave Handbook of Comparative Economics by : Elodie Douarin
Download or read book The Palgrave Handbook of Comparative Economics written by Elodie Douarin and published by Springer Nature. This book was released on 2021-02-13 with total page 982 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to define comparative economics and to illustrate the breadth and depth of its contribution. It starts with an historiography of the field, arguing for a continued legacy of comparative economic systems, which compared socialism and capitalism, a field which some argued should have been replaced by institutional economics after the fall of the Berlin Wall. The process of transition to market capitalism is reviewed, and itself exemplifies a new combination of comparative analysis with a focus on institutional development. Going beyond, chapters broadening the application of comparative analysis and applying it to new issues and approaches, including the role and definition of institutions, subjective wellbeing, inequality, populism, demography, and novel methodologies. Overall, comparative economics has evolved in the past 30 years, and remains a powerful approach for analyzing important issues.
Book Synopsis Optimal Shape Design for Elliptic Systems by : O. Pironneau
Download or read book Optimal Shape Design for Elliptic Systems written by O. Pironneau and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of optimal shape design can be arrived at by asking the following question: "What is the best shape for a physical system?" This book is an applications-oriented study of such physical systems; in particular, those which can be described by an elliptic partial differential equation and where the shape is found by the minimum of a single criterion function. There are many problems of this type in high-technology industries. In fact, most numerical simulations of physical systems are solved not to gain better understanding of the phenomena but to obtain better control and design. Problems of this type are described in Chapter 2. Traditionally, optimal shape design has been treated as a branch of the calculus of variations and more specifically of optimal control. This subject interfaces with no less than four fields: optimization, optimal control, partial differential equations (PDEs), and their numerical solutions-this is the most difficult aspect of the subject. Each of these fields is reviewed briefly: PDEs (Chapter 1), optimization (Chapter 4), optimal control (Chapter 5), and numerical methods (Chapters 1 and 4).
