摘　　要：分析了协同仿真环境(CSE)系统流程管理中的基本PN模型,提出了基于Petri网的CSE离散事件动态系统模型,并将该模型作为CSE系统PN模型中流程的仿真任务的执行单元,建立了基于多Agent技术的仿真组件模型。通过两种模型的综合集成,论述了CSE系统的体系模型及其运行模式,实现了对复杂产品仿真流程的建模和控制,以及多种仿真任务的协同运行。最后,通过开发的仿真平台对某悬挂系统的应用验证了该方法的可行性。In the process of complex product development, the simulation analysis for product performance was faced with the needs of collaborative simulation. Analyzing the basic PN models of the process management system in collaborative simulation environment （CSE）, the CSE discrete event dynamic system（DEDS） model was presented based on Petri net. As the implementation unit of simulation tasks in the CSE PN process, simulation component model was built based on multi--agent technology. Through integrating the two models, the CSE system architecture model and its running mode were discussed, to achieve modeling and control of simulation process, and collaborative running of various simulation tasks. Finally, the proposed modeling approach was applied in the suspension system on the simulation platform developed and its feasibility was demonstrated.
