This book was released on 2008 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the context of Model Driven Engineering, the use of multiple modeling paradigms for developing complex systems is both unavoidable and essential. It results in the heterogeneity of the models representing the considered system and makes global reasoning about the system difficult. The objective of multi-paradigm modeling is to ease the joint use of heterogeneous models during the development cycle. In the work presented in this dissertation, we focus on the study of the heterogeneity of models and propose an approach to multi-paradigm modeling. We first qualify the causes of the heterogeneity of models with respect to the development cycle and we identify several types of heterogeneity. On this basis, we propose a framework for the study of the domain of multi-paradigm modeling with several research axes. The multidisciplinarity of multi-paradigm modeling allows the use of techniques from various fields. We propose a survey and a classification of the techniques which are relevant with respect to heterogeneity. Then we present ModHel’X, the approach to the composition of models for multi-paradigm modeling that we developed. It relies on the concept of model of computation and allows: (1) the specification of the semantics of a modeling language in an executable way by specializing an abstract semantics for models of computation that we developed; (2) the explicit specification of the composition mechanism between heterogeneous models through a special modeling structure called interface block; and (3) the simulation of the global behavior of heterogeneous models thanks to a generic execution algorithm that we defined.

This book was released on 2004 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'étude des systèmes complexes est en passe de devenir une science, avec l'informatique comme l'un des supports possibles pour son développement. Le travail présenté ici participe à ce courant en exposant une recherche sur le couplage et l'interopérabilité des modèles de simulation. Nous abordons cette question en trois points : l'intégration formelle, l'intégration opérationnelle, l'intégration pour la simulation multi-échelles. Pour illustrer notre réflexion, nous avons choisi un système proies-prédateurs emprunté à l'écologie marine. Ceci nous amène à effectuer un rapprochement entre le paradigme d'agents réactifs situés, intéressant pour la simulation des comportements des prédateurs, et le formalisme DEVS, issu de la théorie des systèmes. Ce dernier permet une formalisation de l'ensemble du modèle couplé, constitué d'un Systèmes Multi-Agents (SMA) et d'un système d'équations différentielles. Nous proposons également un framework d'intégration de modèles hétérogènes qui se démarque principalement par la notion de connecteur (ou wrapper), basé sur l'algorithmique des simulateurs abstraits de DEVS et la description des modèles et de leur couplage via une application XML. Enfin, nous développpons une méthode de couplage pour le transfert de propriétés entre niveaux d'organisation (ou transfert d'échelles). En nous basant sur cette méthode, nous construisons un modèle mathématique à partir de simulations du SMA qui nous permet de le coupler avec un modèle classique d'interaction proies-prédateurs. Cette application illustre l'importance de la prise en compte du niveau micro sur l'évolution du niveau macro d'un système dynamique particulier.

Available in PDF, EPUB and Kindle. Book excerpt: Cet ouvrage s'adresse aux étudiants de master des universités et aux élèves des écoles d'ingénieurs ainsi qu'aux mathématiciens, informaticiens et chercheurs de diverses disciplines qui sont amenés à créer des modèles dans leur domaine. -La modélisation informatique à base d'agents permet de modéliser, à l'échelle macroscopique, des systèmes complexes à partir du comportement à l'échelle microscopique d'un grand nombre de leurs composants. L'objectif de ce livre se décline en cinq points complémentaires : - Présenter au lecteur un panorama des approches de modélisation et simulation à base d'agents sous la forme de 11 exemples représentatifs puisés dans différents domaines scientifiques et technologiques. - Proposer un cadre commun de définitions et une ébauche de démarche de conception qui permettent de fournir, au-delà de leur diversité apparente, une base sinon théorique du moins pratique de ces approches. - Présenter les outils informatiques existants pour concevoir, spécifier, programmer et exploiter ces modèles. - Introduire des approches mathématiques pour spécifier les comportements individuels des agents, caractériser leur comportement global, et effectuer les changements d'échelle concernés.- Aborder, enfin, les questions de recherche soulevées par l'usage de ces approches dans le cadre de la modélisation des systèmes complexes. - Chaque chapitre a été conçu pour répondre aux questions que peuvent se poser les lecteurs qui découvrent ce nouveau paradigme ou à ceux qui le connaissent mais souhaitent aller plus loin
Book Synopsis Modélisation de systèmes complexes par composition by : Thomas Paris
Download or read book Modélisation de systèmes complexes par composition written by Thomas Paris and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le contexte de ce travail est la Modélisation et Simulation (M&S) de systèmes complexes. Leur étude nécessite de combiner plusieurs points de vue (échelles temporelles et spatiales, domaines scientifiques et formalismes, niveaux de résolution...). Le challenge est l'intégration rigoureuse de ces différentes perspectives sur un système au sein d'une démarche de M&S. La multi-modélisation et la co-simulation sont deux approches prometteuses pour cela. La difficulté sous-jacente est de fournir une démarche modulaire, hiérarchique, dotée d'une approche d'intégration de composants hétérogènes rigoureuse et associée à un environnement logiciel supportant l'ensemble du cycle de M&S pour la mettre en pratique. MECSYCO (Multi-agent Environment for Complex System CO-simulation) est un intergiciel de co-simulation se focalisant sur la réutilisation de modèles issus d'autres logiciels. Il se base sur une stratégie d'encapsulation logicielle et formelle fondée sur DEVS, fournit des mécanismes de gestion des hétérogénéités, et assure une co-simulation décentralisée et modulaire. MECSYCO répond au besoin d'intégration de composants hétérogènes au sein d'une co-simulation, mais ne propose pas de démarche complète comprenant l'ensemble des propriétés énoncées précédemment comme la possibilité de hiérarchiser. Pour pallier à ce manque, dans la continuité des travaux sur MECSYCO nous proposons une démarche de multi-modélisation et co-simulation descriptive autorisant la construction incrémentale de multi-modèles à partir de modèles issus d'autres logiciels. Notre démarche est décomposée en 3 étapes : l'intégration, la multi-modélisation et enfin l'expérimentation. Chaque élément produit lors de ces étapes est associé à une description permettant de le manipuler. L'utilisation de descriptions complète le processus d'intégration, permet la construction incrémentale et modulaire des multi-modèles, et isole l'expérimentation. Nous mettons ensuite en place un environnement de développement basé sur des langages dédiés aux descriptions, et nous automatisons le passage d'une description d'expérience à sa co-simulation effective. C'est une démarche d'Ingénierie Dirigée par les Modèles qui nous permet de mettre en pratique notre approche en facilitant le travail des modélisateurs et en évitant les erreurs d'implémentation. Nos contributions sont évaluées sur plusieurs expériences dont la reprise d'un multi-modèle d'autoroute hybride et un exemple de thermique des bâtiments.

Book Synopsis Chemical Product Design by : E. L. Cussler
Download or read book Chemical Product Design written by E. L. Cussler and published by Cambridge University Press. This book was released on 2001-04-16 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until recently, the chemical industry has been dominated by the manufacture of bulk commodity chemicals such as benzene, ammonia, and polypropylene. However, over the last decade a significant shift occurred. Now most chemical companies devote any new resources to the design and manufacture of specialty, high value-added chemical products such as pharmaceuticals, cosmetics, and electronic coatings. Although the jobs held by chemical engineers have also changed to reflect this altered business, their training has remained static, emphasizing traditional commodities. This ground-breaking text starts to redress the balance between commodities and higher value-added products. It expands the scope of chemical engineering design to encompass both process design and product design. The authors use a four-step procedure for chemical product design - needs, ideas, selection, manufacture - drawing numerous examples from industry to illustrate the discussion. The book concludes with a brief review of the economic issues. Chemical engineering students and beginning chemical engineers will find this text an inviting introduction to chemical product design.

Book Synopsis Simulating Societies by : Nigel Gilbert
Download or read book Simulating Societies written by Nigel Gilbert and published by Routledge. This book was released on 2018-05-15 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most exciting and productive areas of academic inquiry are often where the interests of two disciplines meet. This is certainly the case for the subject of this book, originally published in 1994, which explores the contribution that computer-based modelling and artificial intelligence can make to understanding fundamental issues in social science. Simulating Societies shows how computer simulations can help to clarify theoretical approaches, contribute to the evaluation of alternative theories, and illuminate one of the major issues of the social sciences: how social phenomena can "emerge" from individual action. The authors discuss how simulation models can be constructed using recently developed artificial intelligence techniques and they consider the methodological issues involved in using such models for theory development, testing and experiment. The introductory chapters situate the book within social science, and suggest why the time was ripe for significant progress, before defining basic terminology, showing how simulation has been used to theorize about organizations, and indicating through examples some of the fundamental issues involved in simulation. The main body of the text provides case studies drawn from economics, anthropology, archaeology, planning, social psychology and sociology. The appeal of this path-breaking book was twofold. It offered an essential introduction to simulation for social scientists and it provided case study applications for computer scientists interested in the latest advances in the burgeoning area of distributed artificial intelligence (DAI) at the time.
Book Synopsis Social Action Systems by : Thomas J. Fararo
Download or read book Social Action Systems written by Thomas J. Fararo and published by Praeger. This book was released on 2001-09-30 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Employing a process philosophical approach, Fararo studies general theoretical sociology as a time-extended tradition with three phases: classical, postclassical, and recent. The author especially focuses on the work of Talcott Parsons and George Homans, two contemporary theorists whose common aspiration was to forge a theoretical foundation for sociology that would serve to unify and integrate all theories growing out of sociological research. Ultimately, the book offers a unique perspective on sociological theory by carefully distinguishing other intellectual orientations from that of general theory.

Book Synopsis Parallel Computing by : Roman Trobec
Download or read book Parallel Computing written by Roman Trobec and published by Springer Science & Business Media. This book was released on 2009-06-18 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of parallel programming and architectures is essential for simulating and solving problems in modern computational practice. There has been rapid progress in microprocessor architecture, interconnection technology and software devel- ment, which are in?uencing directly the rapid growth of parallel and distributed computing. However, in order to make these bene?ts usable in practice, this dev- opment must be accompanied by progress in the design, analysis and application aspects of parallel algorithms. In particular, new approaches from parallel num- ics are important for solving complex computational problems on parallel and/or distributed systems. The contributions to this book are focused on topics most concerned in the trends of today’s parallel computing. These range from parallel algorithmics, progr- ming, tools, network computing to future parallel computing. Particular attention is paid to parallel numerics: linear algebra, differential equations, numerical integ- tion, number theory and their applications in computer simulations, which together form the kernel of the monograph. We expect that the book will be of interest to scientists working on parallel computing, doctoral students, teachers, engineers and mathematicians dealing with numerical applications and computer simulations of natural phenomena.
