基于面向对象着色Petri网的FMS对象类划分及建模

Object Classcification and Modeling of FMS Based on Object_oriented Petri Net

基于面向对象着色Ｐｅｔｒｉ网模型，利用Ｐｅｔｒｉ网和面向对象技术相结合的方法，把ＦＭＳ的物理组成分为５个对象类。每一对象类对应于一个封装的对象子网，用消息位置把各子网集成起来。该模型真实而全面地反映了ＦＭＳ的生产运行，为开发良好的ＦＭＳ在线控制器以及离线仿真器提供了一个很好的模型。

In this paper, a FMS is classified as five object classes under object-oriented concept, which are job, machining equipment, AGV, pallet and tool classes. Using OOCPN, each class corresponds to an encapsulated object subnet and then those subnets are connected by message places. The obtained OOCPN can describe most FMS and simulate their operations. A typical example is illustrated in this paper.
