Resource Management Modeling of Parallel Scheduling for Multi-project Based on CPN

The modeling of parallel scheduling for multi-project is one of the most important parts to plan and control multi-project management. The characteristics of the parallel scheduling for multi-project are analyzed. Petri net is good at describing the random, inter task concurrency, synchronization and parallel, so it can express the characteristics of the parallel scheduling of the multi-project well. It overcomes the failings of current parallel scheduling model for multi- project modeling. The typical example and analysis method are introduced and the feasibility and effectiveness of the model to parallel schedule for multi-project based on CPN are proved.
