Construction automobile

vignette|Une chaîne d'assemblage La construction automobile est la branche d'activité économique qui rassemble les activités de conception, de fabrication et de commercialisation des véhicules de tourisme, utilitaires légers et poids-lourds. Histoire L'histoire de la construction automobile est liée à celle de la consommation de masse : au début du , le modèle fordiste devient l'archétype de l'économie moderne : division du travail (avec la parcellisation des tâches, ou « organisation scientifique du travail » développée par Taylor, qui conduit à l'émergence de la figure de l'ouvrier spécialisé, OS), standardisation et hausse du pouvoir d'achat des ouvriers afin qu'ils puissent consommer et ainsi alimenter la demande. Dans les années 1970, un modèle concurrent, le toyotisme, émerge au Japon, caractérisé en particulier par une gestion en flux tendus. Alors qu'émerge un nouveau modèle économique (post-fordisme, post-industrialisation, société de l'information, etc.), le sec

Proposal of a Closed Loop Framework for the Improvement of Industrial Systems' Life Cycle Performances: Experiences from the LinkedDesign Project

Ana Milicic

The context where European manufacturers of industrial systems operate has dramatically changed over recent years: the pressure of emerging countries they have to face, policy makers' environmental laws and industrial companies' interests are pushing towards sustainable manufacturing and a holistic view of industrial systems. Designers and system engineers are the main actors involved, because they have high influence on product life cycle costs and environmental impacts. However they need tools to pursue a holistic view. The aim of this paper is to propose a closed loop framework to improve life cycle performances of industrial systems, focusing on the automotive sector. (C) 2015 The Authors.

The Application of Fuel-Cell and Battery Technologies in Unmanned Aerial Vehicles (UAVs): A Dynamic Study

Claire Marie Isabelle Bernier, Hossein Pourrahmani, Jan Van Herle

The harmful impacts of fossil-fuel-based engines on the environment have resulted in the development of other alternatives for different types of vehicles. Currently, batteries and fuel cells are being used in the automotive industry, while promising progress in the maritime and aerospace sectors is foreseen. As a case study in the aerospace sector, an unmanned aerial vehicle (UAV) was considered. The goal and the novelty of this study are in its analysis of the possibility of providing 960 W of power for a UAV with a weight of 14 kg using a hybrid system of a lithium-ion (Li-ion) battery and proton-exchange membrane fuel cell (PEMFC). The dynamic performance of the system was analyzed considering three different load profiles over time in an optimized condition. PEMFC was the main supplier of power, while the battery intervened when the power load was high for the PEMFC and the system demanded an immediate response to the changes in power load. Additionally, the impacts of the operating temperature and the C-rate of the battery were characterized by the state of the charge of the battery to better indicate the overall performance of the system.

An ontology-based approach for Product Lifecycle Management

Aristeidis Matsokis

Ontologies are rapidly becoming popular in various research fields. There is a tendency both in converting existing models into ontologies and in creating new models. In this work we are focusing on Closed-Loop Product Lifecycle Management (PLM) models. An ontology model of a Product Data and Knowledge Management Semantic Object Model for PLM has been developed, with the aim of implementing ontology advantages and features into the model. An initial effort of developing the model into an ontology using Web Ontology Language-Description Logic (OWL-DL) is described in detail and the background and the motives for converting existing PLM models to ontologies is provided. The new model facilitates several of the OWL-DL capabilities, while maintaining previously achieved characteristics. Furthermore, a case study is presented based on application scenarios on the automotive industry. This case study deals with data integration and interoperability problems, in which a significant number of reasoning capabilities is implemented. (C) 2010 Elsevier B.V. All rights reserved.
