Abstract:

Some deficiencies were analyzed for current design change management of conceptual design. This paper proposed a solution for conceptual design change management,where the document relationships combined with configuration management.It aimed at the structure and composition uncertainty of conceptual design in product design chain. On the basis of analyzing existing conceptual design procedures, the conceptual design flow of product design chain was constructed. In conceptual design phase, the document relationships were defined and formally described, a design change control processing was proposed based on configuration management for conceptual design of product design chain. The concept of document matrix tree was proposed originally, and the method can overcome insufficiency which the pattern of design change management based on document cannot determine the change of proliferation scope. This paper achieves the integrity, consistency and effectiveness of document relationship information among the partners of design chain.
