Abstract:

The design process of products is a complex systematic engineering integrating multifold knowledge. In this paper,by an integrated analysis of existing modeling methods of the design process for products,a novel ap-proach to information modeling is proposed based on the expanded directed graph and the fuzzy design structure ma-trix,and the inform ation dependence of activities is quantitatively described.Then.process re-engineering is im-plemented by the decomposition,tear and partition of activities.Moreover,a fuzzy order based on the inform ation correlation grade of coupling activities is carried out to guide the activity decomposition,with the coresponding al-gorithm being also provided.A case of punch die design is finally presented to verify the efectiveness and feasibili-ty of the proposed method.

Key words: product design, process modeling, fuzzy design, structure matrix, punch die
