Research on Project Level Collaborative Design Process Oriented to Complex Product

This paper established a decomposition hierarchical network model of project level collaborative design process, based on work breakdown structure WBS, for character complex product collaborative design in dynamic alliance. The workflow of product collaborative design was established using time sequence Petri net, and the key assignment which has influence on design schedule and all design time were solved, after analyzing and comparing existing model method of collaborative design. And then experiments were used to verify. Theses technology support time management of workflow in project collaborative and shorten development cycle of collaborative project.
