Using Viewpoints and CG for the Representation and Management of a Corporate Memory in Concurrent Engineering

In Concurrent Engineering, several participants (designers, managers,...) stemming from different specialities, collaborate in order to build a system. In this paper, we propose a representation with the Conceptual Graph formalism to keep a trace of the design process in Concurrent Engineering as a project memory. Such design process is a cycle of individual design and collaborative evaluation. In order to facilitate knowledge extraction from this memory and to ensure the evolution of knowledge, we define a viewpoints management. This management is based in our study of viewpoints in Conceptual Graphs.
