Abstract: The process model of product collaborative design is the basis of designing the modular and hierarchical collaboration-supported system. The current process models only express some aspects of design process. Moreover the models mainly analyze the qualitative features of design process， and the quantitative analysis of design process performances is lacked. After the analysis of the features of current collaborative design process， the design process modeling method based on hierarchy colored Petri-net (CPN) is proposed. And the method of analyzing process features is developed.

Key words: collaborative design, hierarchy colored Petri-net, process modeling, performance analysis
