用面向对象方法实现基于Petri网的FMS动态调度仿真

The Realization of Dynamic Scheduling Simulation of FMS Based on Petri-net Theory with Object-oriented Method

Ｐｅｔｒｉ网模型是ＦＭＳ动态仿真的有利工具．本文利用面向对象方法对ＦＭＳ和有色赋时Ｐｅｔｒｉ网进行了描述，并根据最小下次事件时间推进原理，利用ＶｉｓｕａｌＣ＋＋建立了动态调度仿真系统．结果表明，面向对象方法具有表达直观、自然，可扩充性，实现容易、简便等优点．

Petri-net theory is a useful tool for the dynamic simulation of FMS.In this paper,we describe colored timed Petri-net and FMS with object-oriented method.And in according to the principle of advancing by order of the next event occuring in the least time,we build a system of dynamic scheduling simulation with the software of Visual C++.The results show that the object-oriented method has many advantages,such as intuitive and natural expression,expansibility,easy realization,simple and convenient,etc.
