Project management technology of complex virtual prototype engineering

The basic research of project management system, COSIM-PM is introduced, which supports the complex virtual prototype engineering. As one important part of the virtual prototype engineering supporting platform COSIM[1], COSIM-PM takes the management and optimization for multi-constrained scheduling and resource planning as its core technology and realizes the overall lifecycle management of complex virtual prototype engineering through planning, controlling, tracking and optimization for personnel/group, scheduling, resource and cost respectively. The structure and typical techniques of COSIM-PM were put forward, and a res-proportion optimization algorithm was discussed in detail. The relation and the integration of COSIM-PM and workflow were summarily presented, and the typical application of COSIM-PM was introduced.
