| In recent years with the rapid pace of market, more violent competition and updated technology, products become more and more complex, new product development becomes more difficult, especially process management calls for more flexibility and faster response. Under this background, to traditional product development method, period seems too long, cost seems too high, and efficiency seems too low, so traditional development method can be very difficult to adapt survival demand of enterprise. These factors promote the application of virtual prototyping technology in product development process and make process management the important issue of research.This article bases on the CIMS/863 program "Complex Product VP Study Based on Collaborative Design and Concurrent Engineering" and NFSC program "Research on Multidisciplinary Modeling for Complex Product in Virtual Prototype Environment". According to the actual demand of implementing virtual prototype in product development process, process modeling is studied on emphasis and corresponding supporting software is developed on the basis of full study of virtual prototyping technology, finally an application demonstration is given.On the base of analysis of virtual prototype, process management, project management, workflow management, PDM, etc, the characters of complex product development process based on virtual prototype are summed up from the evolvements of product development modes; According to process engineering theories, a process modeling method which is multi-view, both graphic and semantic is presented and expatiated; Project management and workflow management are integrated, product development process system based on virtual prototype is established, including project management, workflow management, person management, work platform etc. The functions of process static modeling, dramatic modeling, process dramatic executing and monitor, teamwork and role assigning are realized.
