The architecture of project management of distributed concurrent product design in a virtual enterprise is put forward. The process of project management and its functions are presented. Product design process coordination is also discussed. First, based on the analysis of traditional project management, project management and coordination of distributed cooperative product design in the virtual enterprise is put forward. Then, aiming at the characteristics of a distributed concurrent product design process, the inherent rules and complex interrelations in product development are studied. Accordingly,the architecture of project management of distributed cooperative product design in a virtual enterprise is presented to adapt to distributed concurrent development of complex products. The main advantages of the architecture are also discussed. Finally, the emphasis is placed on the project management process.Its main functions are set forth, such as project definition, task decomposition and distribution, resource constraints and dynamic resource scheduling, process fusion, task scheduling and monitoring,project plan, cost and quality evaluation, etc.
