摘要
网中网(Nets-within-Nets)理论提出传统Petri网中的标记(Token)可以用来描述对象,即标记也可以是一个Petri网,称为对象网(ObjectNets)。网中网支持用面向对象的技术描述现实世界的对象模型。参考网(ReferenceNets)根据网中网的理论并且结合了着色Petri网的概念,动态地创建网实例(NetInstance)作为对象网,变迁之间通过同步通道通信。本文根据网中网理论结合建模开发工具Renew,构建了柔性制造系统的宏观模型。
The nets-within-nets theory provides an innovative modeling technique by tokens .being able to be interpreted as objects, giving tokens themselves the structure of a Petfi net. These nets, called object nets, also support the object oriented modeling technique as they may represent real world objects . Reference Nets based the theory of nets-within-nets and extend the basie eoncepts of Colored Petri nets by dynamic creation of net instance, transition synchronization via synchronous channels. A Flexible Manufacturing System macroseopieal model is introduced within the Renew tool, a tool for drawing and simulating reference nets.
