Abstract: To apply the technologies of Collaborative Modeling/Simulation/Project Management to the lifecycle of Complex System Virtual Prototype (CSVP), a support environment for CSVP based on these technologies was designed, which was built on the base of WINDOWS operation system, TCP/IP Network protocol, commercial relation database (ORACLE 8i) and Simulation Grid that supported cross-area collaboration and simulation resource sharing. It provided support for the collaborative modeling and simulation of all subsystems under complex design targets. The four-layer architecture of CSVP was described. The data, models, toolsets, personnel and process can be managed and optimized under the architecture during the process of system design, development and application. The function design, implementation technique and research status of each layer were also presented here in detail. The designed environment can be utilized to design and evaluate products though its lifecycle, so that the cost of products is reduced and the efficiency of development of products is improved.
