一种离散事件系统建模新方法及其应用

为增强Ｐｅｔｒｉ网技术和Ｏ－Ｏ技术相结合而形成的ＯＯＰＮ的描述能力，提出了一种基于消息驱动机制的新型ＯＯＰＮ——ＭＯＰＮ的定义及其特性，它用面向对象方法为系统建立起整体框架，用有色Ｐｅｔｒｉ网具体实现各个对象，并加入消息驱动机制以在对象间传递消息，能较好地将Ｏ－Ｏ技术和Ｐｅｔｒｉ网的优点结合起来．用离散事件系统的典型实例——ＦＭＳ的建模来说明其在离散事件系统建模、分析中的应用

New Method for DES Modeling and Application

Distributed event system(DES) is a kind of complex system that works with distributed asynchronous and concurrent properties.There are many instances of DES in communication,manufacturing and information industries,so it is important to build a DES model to describe their behavior.Object oriented Petri net(OOPN) which combines the concepts of Petri nets and object oriented technoloy is very useful in analyzing the DES.To involve much information in the net,a new approach, message driven object oriented Petri nets(MOPN),was defined,and its properties were introduced.A model of FMS,which is a kind of typical DES,was given as an example.
