Ingénierie des systèmes d'information produit : une approche méthodologique centrée réutilisation de patrons.

In industrial organisations, the product information systems (PIS) support the technical data management of products and their process of design/production. The current economic context makes these PIS strategic for these organisations. Currently, these organisations have many difficulties in the development of these systems. The object of this research is to define a methodological framework adapted to PIS engineering and allowing to reduce these difficulties. In this article, firstly, we identify these difficulties and we augue the necessity of a reuse approach for a development "in gap" of these systems. Then, we distinguish different forms of reuse already introduced in software engineering, by emphasising more particularly design patterns reuse. The proposed methodological framework is mainly based on the reuse of patterns during the entire development process of PIS. These patterns are used to define recurrent development problems of these systems and to allow the reuse of associated solutions already defined. This paper illustrates this approach with the definition and the specification of a pattern adapted to a mechanical design problem.
