From Functional Analysis to CAD Modelling Based on Knowledge Transformation Driven by the Design Process

Part 5: Modelling for PLMInternational audienceMost of industries currently spend too much time to find information on past product design process. This considerably reduces the time it can devote to innovation. The authors assume that the design process meta-model seems very interesting for modelling the design rational and then for accelerating information retrieval. Indeed, the model of the design process partly supports every resources involved in decision making activities (i.e. who, what, when, why, where, how). The authors therefore propose the use of a MBE architecture for driving the product modelling based on the design process model. The UML activity diagrams and the IDEFØ meta-model are linked for supporting automatic generation ofproduct models using specific transformation knowledge. The CAD model is partly generated from the product functional analysis

Operational framework based on modeling languages to support product repository implementation.

Part 3: Tools and MethodologiesInternational audienceEmbracing Product Lifecycle Management approach involves integrating a product repository in the company information system. From customer's needs to disposal stage, several product representations exist. The product repository purpose is to secure consistency of one product representation with the others. This paper presents an operational modeling framework that supports product repository implementation. In order to ensure consistency, this framework identifies correspondences between entities of languages (“trade” languages and standard languages). The presented concepts are illustrated with correspondences between language entities of product designed and productplanned to be built Bills of Materials
