Abstract: Aiming at the problem of workflow modeling in design process with changing the product structure, a dynamic workflow modeling method was put forward based on Product Structure Tree(PST). Workflow active template library of product and component was constructed, and the mapping relation between workflow template of components and PST was established. Through dynamic node refinement, product workflow model instance was formed. The actual engineering case of large-scale antenna structure development was used to verify the instance. The result showed that workflow model of product design process was generated dynamically according to the components instance of PST and its membership relation at run time, thus the dynamic workflow modeling problem in product design process was solved.

Key words: product structure tree, workflow template, dynamic node refinement, workflow instance, product design
