Product Modelling for Configurable Design in Advanced CAD System

摘要

Design for configuration provides an efficient and effective means to realise the product variety. This chapter tackles the product modelling in advanced CAD systems for product configuration using an UML (Unified Modelling Language) approach and a computational model. The introduction of fuzziness to capture the subjective nature of the design for configuration permits to consider different use cases in the early conceptual design phase of the product. Furthermore, the building of multiple fuzzy models, which correspond to the multiple views of a configurable product, permits to propose both the functional architecture and physical architecture to configure a product. Then, the computational model permits to generate a solution which satisfies the customer requirement and the constraints of different process views. The association of the computational model and the CAD parametric model allows the generation of different configurations in a CAD system. An application shows the potential of the proposed approach.
