Product Module Identification Based on Assured Customer Requirements

Modular design includes module identification and module assembly. To obtain the optimization project of module identification, the assured customer requirements must be gained. So, the gain technology of assured customer requirements, which using gray system theory, is proposed in this paper. Then, the assured customer requirements should be change to the factors of product function, performance, physics and so on. After to gain above factors' relation matrix, a synthesis design structure matrix can be obtain. An optimization function which based on the axiomatic design theory is established. Then, a new numerical optimization approach about product module identification, which used improved harmony search algorithm, is presented in this paper. This approach is tested several times. The optimization project can be attaining at each time. The result demonstrates the feasibility of the proposed approaches. (C) 2011 Published by Elsevier Ltd.
