Abstract: Module clustering is foundation of modular design for complex product. Its performance counts for much in efficiency of product design, manufacture and assembly. However, the existing methods lack performance evaluation on modules after module clustering. In this paper, D-S evidence theory is adopted to make uncertain and incomplete evaluation on module satisfaction according to assembly complexity, manufacturability, modularity, stability, sculpt ion and compactness. A two-layered evaluation method on module clustering is proposed, and its evaluation accords with process of human thinking and judgment. The agility, validity and rationality of the method have been illustrated by an instance.

Key words: computer application, comprehensive evaluation, D-S evidence reasoning, module clustering, contributive ratio
