摘    要:传统的Petri网方法不能解决实际系统运行中出现的不确定性,资源共享等问题。该文定义了一种扩展有色Petri网——集控Petri网方法。它通过引入过程变迁,不确定性弧,全局库所和赋予每个托肯一个数据结构增加了Petri网的建模能力。重点讨论了使用面向对象方法设计和开发的基于集控Petri网方法的建模和仿真工具。给出系统的面向对象的类层次结构、核心数据结构和用户界面为了便于和其它建模和仿真工具进行有效的集成,所设计的软件采用了中性文件的机制来保存模型结构和数据。

关 键 词:集控Petri网  面向对象  建模仿真

Abstract:The traditional Petri net methods can not solve the problems of uncertainties and resource sharing existed in practical system operation. An extended color Petri net control and integration net method is defined. Through introducing procedure transition, uncertainty arc, global place and associating data structure to every token, the modeling ability of Petri net is enhanced. The main focus of this paper is to present the object orient method in developing the modeling and simulation tool based on the control and integration net. The system's class structure, kernel data structure and user interface are given. In order to be able to integrate with other software tool, a neutral mechanism is used by the designed software to restore the information of model structure and data.
