The study of a wind turbine is a perfect example of a project that requires an interdisciplinary team design, in fact for such a project mechanical structure, and CFD （computational fluid dynamics） designers are necessary. In addition, in the last years, the multi domain design has been supported by the continuous development of software for computer-aided design and the unceasing increase of the connection between performances and computer costs： the final aim is to propose the instruments that assist the designer throughout all the steps of the project. The multi domain design, illustrated in this article, is based on how to design the wind turbine, and it is not about process management and manufacturability. In particular, in the article, the emphasis will be placed on the integration between CAD and mathematical software of general type and on the CAD-CAE integration.展开更多

This paper presents the modeling of welded construction maintenance activities by IDEF0 （Integration DEFinition） methodology. Modeling maintenance activities on a welded construction using IDEF0 methodology, the software implementation of which is the BPWin （Business Process windows） CASE （Computer Aided Software Engineering） tool, allows functional decomposition and design at all levels of the system that consists of workers, machines, materials, computers and information.展开更多
