支持并行调度的多项目资源管理CPN建模

构建良好的多项目资源调度模型已成为项目型企业多项目管理计划与控制的关键性基础工作。在分析多项目并行调度特点的基础上，基于Petri网擅长描述随机性、任务间并发、同步、并行等系统特征的优势，克服当前已有的多项目并行调度模型的不足，构建了基于CPN的多项目并行调度模型。通过建模实例阐述了模型的仿真分析方法，证明了基于着色Petri网构建多项目并行调度模型的可行性和有效性。  

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.
