Abstract

In order to solve the dynamic modification problem of workflow model in product development process,a method of dynamic workflow modeling is presented based on product structure tree (PST).In the method, a dynamic node was introduced into a workflow template, and the refinement rule of a dynamic node was proposed. Through mapping the components of PTS onto the workflow template,the component instances and their affiliation used as refinement input elements,then the dynamic workflow nodes were refined. Validation in the actual engineering case of large-scale antenna development shows that the workflow instance was constructed dynamically at run-time.
