Abstract: In this paper， the evolving process mechanism of Robocup that is a common MAS problem based on event-driven， constraint-triggered and Agent"s decision-pushed is analyzed. An evolving process model of MAS is generalized and built based on Petri net. Furthermore， conceptual design process is analyzed， and then an evolving process of conceptual design automation system is described based on above evolving process model， which is the basis for implementing a conceptual design automation system.

摘要： 通过对典型多Agent系统问题中基于事件驱动、约束触发和Agent自主决策的过程演进机理的分析，建立了一个基于Petri网的多Agent系统演进过程模型。进一步对产品概念设计的演进过程进行分析，描述产品概念设计自动化系统的演进过程，以支持基于多Agent系统的产品概念设计自动化系统的建立。
