Download or read book Identification and Fault Diagnosis of Industrial Closed loop Discrete Event Systems written by Matthias Roth and published by Logos Verlag Berlin GmbH. This book was released on 2010 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Die Wettbewerbsfahigkeit von Industrieunternehmen hangt massgeblich von der Produktivitat der eingesetzten Anlagen und Produktionsprozesse ab. Um ein hohes Mass an Produktivitat zu garantieren, mussen durch Fehler verursachte Standzeiten so kurz wir moglich gehalten werden. Dazu werden effiziente Methoden zur Fehlerdiagnose benotigt. In der vorliegenden Arbeit wurde ein modellbasiertes Diagnose-Verfahren fur ereignisdiskrete Closed-Loop Systeme entwickelt. Die betrachteten Systeme bestehen aus dem geschlossenen Kreis von Steuerung und Prozess. Durch den systematischen Vergleich von aktuell beobachtetem und durch ein Systemmodell erwartetem Verhalten konnen Fehler in Echtzeit erkannt und isoliert werden. In der Arbeit wurden geeignete Modellidentifikationsverfahren fur Ereignisdiskrete Systeme entwickelt, sodass die aufwandige manuelle Modellbildung vermieden wird. Die entwickelten Methoden wurden im Labor und im Rahmen einer Industrieanwendung erfolgreich getestet.
Download or read book Discrete Event Systems in Dioid Algebra and Conventional Algebra written by Philippe Declerck and published by John Wiley & Sons. This book was released on 2013-02-13 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book concerns the use of dioid algebra as (max, +) algebra to treat the synchronization of tasks expressed by the maximum of the ends of the tasks conditioning the beginning of another task – a criterion of linear programming. A classical example is the departure time of a train which should wait for the arrival of other trains in order to allow for the changeover of passengers. The content focuses on the modeling of a class of dynamic systems usually called “discrete event systems” where the timing of the events is crucial. Events are viewed as sudden changes in a process which is, essentially, a man-made system, such as automated manufacturing lines or transportation systems. Its main advantage is its formalism which allows us to clearly describe complex notions and the possibilities to transpose theoretical results between dioids and practical applications.

This book was released on 2012-11-21 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cet ouvrage présente différents modèles discrets en dynamique pour la modélisation de phénomènes mécaniques non linéaires liés au frottement ou à l’impact. Les sollicitations sont exposées dans un cadre déterministe et stochastique. Pour ce dernier, le cas de variétés de configuration euclidienne ou riemannienne est abordé. La difficulté réside dans le type d’équations différentielles non linéaires particulières utilisées. Le cadre théorique ainsi que des schémas numériques sont détaillés pour chaque équation. Trois types de problèmes sont d’abord étudiés dans le cas particulier d’un solide à un degré de liberté : la force de frottement, la loi d’impact en déterministe et le frottement dans un cadre stochastique. Ensuite, de nombreux exemples sont commentés et fournissent, dans un cadre théorique ou applicatif, de nombreux modèles accompagnés de leurs schémas numériques. Des rappels théoriques fondamentaux sont proposés ainsi que deux preuves complètes de convergence de schémas numériques dans le cas du frottement déterministe ou stochastique.
Download or read book Discrete Continuous and Hybrid Petri Nets written by René David and published by Springer Science & Business Media. This book was released on 2010-11-09 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: Petri Nets were introduced and still successfully used to analyze and model discrete event systems especially in engineering and computer sciences such as in automatic control. Recently this discrete Petri Nets formalism was successfully extended to continuous and hybrid systems. This monograph presents a well written and clearly organized introduction in the standard methods of Petri Nets with the aim to reach an accurate understanding of continuous and hybrid Petri Nets, while preserving the consistency of basic concepts throughout the book. The book is a monograph as well as a didactic tool which is easy to understand due to many simple solved examples and detailed figures. In its second completely reworked edition various sections, concepts and recently developed algorithms are added as well as additional examples/exercises.
Download or read book Fiabilit technique et humaine written by LYONNET Patrick and published by Lavoisier. This book was released on 2012-10-22 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: De tout temps l’homme a sans doute voulu construire des choses fiables. Mais les évaluations quantifiées, probabilisées ont vu le jour récemment d’abord pour systèmes militaires (missiles, satellites) puis nucléaires, automobiles et les biens d’équipements. On peut citer que dès 1906 les constructeurs de tubes à vides américains se sont préoccupés de fiabilité, de là est née la fiabilité électronique, puis mécanique, informatique et humaine des systèmes et composants. Cette évolution contemporaine a produit de nombreux outils, concepts et méthodes. Ces développements sont au centre de l’ouvrage. Fiabilité Technique et Humaine rassemble les concepts, techniques et outils de la fiabilité des composants et systèmes en considérant toutes les technologies et dimensions, notamment la mécanique, l’électronique, l’informatique et les aspects humains. En effet, les erreurs humaines sont à l’origine de nombreuses défaillances et de ce fait ne peuvent être ignorées lors de la conception ou du maintien des installations. Les diverses formes de fiabilité, prévisionnelle, expérimentale et opérationnelle sont explicitées et illustrées aux travers d’applications industrielles. Les concepts, outils et techniques de fiabilité les plus complexes sont présentés à partir d’exemples permettant au lecteur de se familiariser avec ce domaine. La présentation très didactique de ces concepts, étayée par plus de 100 exercices et problèmes corrigés en fait un ouvrage incontournable pour la maîtrise de la fiabilité technique et humaine.
Download or read book Multi Agent Systems and Agent Based Simulation written by Jaime S. Sichman and published by Springer. This book was released on 2005-07-12 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fifteen papers were presented at the first workshop on Multi-Agent Systems and Agent-Based Simulation held as part of the Agents World conference in Paris, July 4-- 6, 1998. The workshop was designed to bring together two developing communities: the multi-agent systems researchers who were the core participants at Agents World, and social scientists interested in using MAS as a research tool. Most of the social sciences were represented, with contributions touching on sociology, management science, economics, psychology, environmental science, ecology, and linguistics. The workshop was organised in association with SimSoc, an informal group of social scientists who have arranged an irregular series of influential workshops on using simulation in the social sciences beginning in 1992. While the papers were quite heterogeneous in substantive domain and in their disciplinary origins, there were several themes which recurred during the workshop. One of these was considered in more depth in a round table discussion led by Jim Doran at the end of the workshop on 'Representing cognition for social simulation', which addressed the issue of whether and how cognition should be modelled. Quite divergent views were expressed, with some participants denying that individual cognition needed to be modelled at all, and others arguing that cognition must be at the centre of social simulation.

CISA encourages the diverse research actors and the industrial one to present the last headways in "Robotics and Automation" fields, notably the experimental demonstration of prototypes. CISA tries to give to the unsupported researchers, a significant access to the new technologies and theories around the topics of Robotics & Automation. The organizers want to give the necessary scientific documents to disposal of the PhD students and researchers of the Mediterranean region. CISA wants to offer to the youth researchers from the south Mediterranean region the opportunities to exchange and to discuss their scientific contributions with the other researchers from all over the world.
