面向对象扩展着色 Petri 网在装配系统中的应用

Modeling Assembly Using ObjectOriented Extended Colored Petri Nets

根据面向对象思想，提出了面向对象扩展着色Ｐｅｔｒｉ网模型（ＯＯＥＣＰＮ）．该模型一方面，具有通用性，可重用性和易扩展性；另一方面，具有简单性、直观性．很好地解决了传统的Ｐｅｔｒｉ网所面临的问题．此外以装配系统为例，阐述了ＯＯＥＣＰＮ的建模方法．

An objectoriented extended colored petri net model was developed for representation of assembly. It provides a new modeling method and can handle features such as routing flexibility,shared resources,lot size and concurrency. The model is compact,and possesses reusability,as opposed to the traditional methods where the structures of the petri net models are not stable. The modularity makes it possible for the model to be enlarged. It is also intuitive for us to understand it clearly and concisely.
