Book excerpt: Le rôle d'une gestion en temps réel des fonctions annexes de production (ex.: transports, outils) est essentiel dans le cadre d'une cellule flexible. Lors d'une analyse de type GRAI, distinguant composantes physiques, informationnelles et décisionnelles, nous proposons trois modes d'allocation d'une ressource de transport. Soit par classes de déplacements, soit par application de règles de gestion, soit, finalement, par ordonnancement local de l'ensemble instantané des déplacements à l'aide d'une méthode de séparation et évaluation progressive (SEP). L'application de nos méthodes nous a permis d'étendre les fonctionnalités d'un produit industriel de simulation par évènements discrets, SIMUFLEX, logiciel dédié aux cellules flexibles de production. En particulier, nous lui avons adjoint le choix de règles de gestion pour les ressources de stockage, fabrication et transport. La validation des modes d'allocation a fait l'objet d'une étude des résultats de simulation à l'aide d'une méthode d'analyse en composantes principales (ACP). A partir d'un cas réel d'une cellule de polissage du verre, nous avons testé différentes politiques de gestion. Ainsi, nous mettons en évidence l'incidence des choix de gestion sur les performances du système de production.

Book Synopsis Contrôle temps réel du déroulement des opérations dans les systèmes de production flexibles by : Rousseau Tawegoum
Download or read book Contrôle temps réel du déroulement des opérations dans les systèmes de production flexibles written by Rousseau Tawegoum and published by . This book was released on 1995 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: La complexité du pilotage temps réel des systèmes de production flexibles nécessite des outils permettant d'exploiter ces flexibilités afin de réagir aux aléas perturbant l'évolution de la production. Nous présentons dans ce mémoire une approche de contrôle en temps réel du déroulement des opérations dans les systèmes de production flexible. Cette approche s'articule d'une part sur l'organisation du pilotage en centres de décisions, et d'autre part sur le contrôle des opérations de transfert et des oprérations de transformation d'état. Nous proposons une structuration du pilotage en centres de décision suivant une architecture de contrôle mixte, incluant les concepts de distribution et de coopéaration. Nous définissons la notion de tâche élémentaire et un ensemble d règles d'agrégation des ressources de base commandables. Ces règles utilisent les relations d'accessibilité et de connexité entre ressources, pour répartir les centres de décision, ce qui permet de définir les compétences de chaque centre de décision au sein de l'architecture. Pour contrôler les opérations de transfert, nous utilisons des fonctions de priorité pour la résolution des conflits d'accès aux ressources, puis nous proposons une heuristique de routage dynamique des produits, prenant en compte les points d'accumulations du sytème de transfert. La surveillance des opérations de traitement est basée sur l'évaluation de l'admissibilité des séquences d'opérations grâce à deux indicateurs. Cette évaluation nous permet, compte tenu des consignes de production et de l'ampleur d'une perturbation, de choisir l'action corrective adaptée à l'évolution du procédé.

Download or read book Génération automatique des procédures de pilotage d'une cellule flexible de production written by Dominique Gendreau and published by . This book was released on 1991 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: La performance des systèmes automatisés de production réside dans leur exploitation optimale, et en particulier dans le choix de nombreuses possibilités offertes pour l'exécution de la production. La conception de la conduite apparait donc comme une phase essentielle dans la conception de la commande de tels systèmes. Notre étude porte sur les cellules flexibles d'usinage pour lesquels nous envisageons une optimisation dans les cycles d'exécution, applicable en temps réel et avec des gains de temps espérés qui vont de la minute à plusieurs heures. Cette préoccupation est celle des entreprises de sous-traitance pour lesquelles les séries de pièces sont petites et les temps de réponse doivent être courts. D’autre part, le programme de production de la cellule est généralement élaboré à la conception du système et donc fige, ce qui ne permet pas de réagir de manière rapide et efficace aux perturbations qui surviennent pendant la production. Enfin, l'aspect générique de la conception de la commande de tels systèmes n'est jamais considéré. Le cas par cas est un état de fait hélas trop souvent constaté. C’est dans ce cadre, constitue par un besoin triple de flexibilité-réactivité-généricité, que se situent nos travaux, et nous nous intéressons plus précisément au module de pilotage, élément clé du système de conduite, puisque décideur de la meilleure stratégie d'exécution de la production applicable sur la cellule

Download or read book Terra 2008 written by Leslie Rainer and published by Getty Publications. This book was released on 2011-06-14 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.
Book Synopsis Architecture and Modern Literature by : David Anton Spurr
Download or read book Architecture and Modern Literature written by David Anton Spurr and published by University of Michigan Press. This book was released on 2017-05-09 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Architecture and Modern Literature explores the representation and interpretation of architectural space in modern literature from the early nineteenth century to the present, with the aim of showing how literary production and architectural construction are related as cultural forms in the historical context of modernity. In addressing this subject, it also examines the larger questions of the relation between literature and architecture and the extent to which these two arts define one another in the social and philosophical contexts of modernity. Architecture and Modern Literature will serve as a foundational introduction to the emerging interdisciplinary study of architecture and literature. David Spurr addresses a broad range of material, including literary, critical, and philosophical works in English, French, and German, and proposes a new historical and theoretical overview of this area, in which modern forms of "meaning" in architecture and literature are related to the discourses of being, dwelling, and homelessness.

Book Synopsis Faecal Sludge Management by : Linda Strande
Download or read book Faecal Sludge Management written by Linda Strande and published by IWA Publishing. This book was released on 2014-08-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.
