Abstract: To conduct effective planning and management on product design process, a modular decomposition method for design process based on fuzzy design structure matrix was proposed. Based on characteristic analysis of variant product design process, the modularization planning principles and implementation framework of product design process were introduced. Then concepts of design process module (DPM) and its input/output items were put forward. The information dependence relationships of design activities in design process were represented by weighted directed graph, and further were mapped to a fuzzy design structure matrix quantificationally. Based on the fuzzy design structure matrix, the DPMs of product design process were created by the transition closure method, and the input/output items of each DPM were obtained. Finally, an example of aluminum profile extrusion product design process was provided to illustrate the application of this method.
