Abstract: Two key technologies of the integration of product research and design processes are studied, which include building up the virtual product models orienting the cycleperiod of products and integrating the project models, workflow models and product models. Further more, the structure of the virtual product models and the integrated frame of the project models, workflow models and product models are presented. Then software systems, able to realize those functions, can be developed.

Key words: virtual product model, product data management, project management
