This book was released on 1994 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le monde de la production subit actuellement des changements importants. La diversification de la production et la multiplication des variantes autour d'un produit de base, tendances de marché récentes, ont rendu la tâche des concepteurs de systèmes d'assemblage plus complexe. L'objectif de cette thèse est d'élaborer une démarche systématique de conception des systèmes flexibles d'assemblage (SFA), capable de s'adapter à cette diversité de production. La première étape de la démarche est une analyse de la famille de produits. Deux analyses sont présentées : la première est une analyse fonctionnelle qui permet de décrire la famille par ses fonctions et la deuxième est une analyse matérielle qui permet une comparaison entre les composants des produits d'une famille. La définition d'un modèle unique permettant de représenter tous les produits d'une famille est l'objet de la deuxième étape. Le modèle basé sur l'utilisation des grammaires de webs permet dans une première phase, de modéliser tous les graphes de produits de la famille et, dans une deuxième phase d'élaborer les gammes d'assemblage. La troisième étape consiste à définir la notion de gamme d'assemblage générique dont le but est de concevoir un SFA unique pour réaliser tous les produits d'une famille donnée. La description d'un système d'assemblage à partir d'une gamme générique se fait en deux parties : la première est une transcription de la gamme en schéma fonctionnel et la deuxième est une étude opératoire des des schémas fonctionnels. A chaque gamme d'assemblage correspond plusieurs schémas opératoires. La sélection d'un certain nombre de ces schémas opératoires nécessite un outil qui permet de les évaluer. Le développement d'un tel outil fait l'objet de la dernière étape de la méthode. L'évaluation d'un système d'assemblage se fait par la simulation du marquage du réseau de Petri coloré temporisé modélisant ce système.

This book was released on 2011-06-28 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrated Design of a Product Family and Its Assembly System presents an integrated approach for the design of a product family and its assembly system, whose main principles consider the product family as a fictitious unique product for which the assembly system is to be devised. It imposes assembly and operation constraints as late as possible in the design process to get liberties in the system design, and adapts the product family at each design stage to integrate the new constraints related to the successive design choices. Integrated Design of a Product Family and Its Assembly System is an important, must-have book for researchers and Ph.D. students in Computer-Integrated Manufacturing, Mechanical Engineering, and Manufacturing, as well as practitioners in the Design, Planning and Production departments in the manufacturing industry. Integrated Design of a Product Family and Its Assembly System is also suitable for use as a textbook in courses such as Computer-Aided Design, Concurrent Engineering, Design for Assembly, Process Planning, and Integrated Design.

This book was released on 1986 with total page 792 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preface Adhesion is a phenomenon architects and civil engineers are not very familiar with. In other disciplines knowledge about surface properties and the background of bonding energies is also far from satisfactory; nevertheless there are many important· applications in concrete engineering, where adhesion is necessary for success and durability. These include: - coating and painting - repair of concrete surfaces - bonding of fresh to old concrete - crack injection - glueing of precast elements - glueing of steel to concrete, etc. In 1981 RILEM established the technical committee 52-RAC 'Resin Adherence to Concrete'. The main aims of the committee's work were - to collect research results and practical experiences - to initiate and coordinate research programs - to develop, on a scientific base, test methods for field and for laboratory purposes. One of the results of the committee's work is a state-of-the-art report, which will be presented orally as a General Report at the International Symposium ISAP '86, and will be printed either in the RILEM journal Materials and Structures or separately. Several test recommendations have been elaborated and will be prepared as drafts for the participants ofISAP '86. These are: - direct tensile test - pull-off test - direct shear test - slant shear test - four-point bending test - dynamic loading test - thermal compatibility test (two versions) - injectibility test.
Download or read book Environmentally Friendly Product Development written by Eberhard Abele and published by Springer Science & Business Media. This book was released on 2007-08-06 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Development of environmentally friendly products gains an increasing - portance in science and in industry. While product development was strongly dedicated to achieve quality, cost and time targets, environmental issues indirectly had always been under consideration by engineers, see Fig. 1. Furthermore a methodology for the development of environm- tally sound products was missing. Despite of significant progress in using computer aided tools for product development and design, environmental aspects were attended. Computer aided tools typically do not include methods for considering environmental issues enabling the designer to - sess a product’s environmental effects. Fig. 1. Vision of Environment as a key target for product development v vi Preface Product related environmental issues are getting more and more political and public awareness. Development of environmentally friendly products has become an action item for both, politics and industry (UNFCCC 1997). Energy consumption is on the agenda and covers pollution and resource saving. Typical topics of directives of the European Union are waste, noise, air pollution, water, nature and biodiversity, soil protection, civil protection and climate change. After the translation into national law the development of environmentally friendly products is a basic approach to contribute to the fulfilment of the topics mentioned above. In the European Community a “Communication from the Commission to the Council and the European Parliament” on “Integrated Product Policy” was adopted on th 18 June 2003 (EC 2003).
