物资调运过程的PETRI网建模及仿真

The Petri Nets Model of a Material Dispatch System and the Designing of its Simulator

本文对三峡工程水泥调运过程用ＰＥＴＲＩ网进行建模，指出了进行调运的关键库所和变迁。讨论了拌和浇筑环节ＰＥＴＲＩ网模型可能存在的不良特性。为解决此类问题设计了仿真器，它很好地实现了调度模拟的功能。同时给出了仿真器的框架和ＤＳＰＮ的仿真算法。

This paper analyzed the modeling of Three Gorges Project(TGP) cement dispatching procedure, which is based on Petri Nets. It pointed out the key place and transition in the Petri Nets model which realized the optimum of dispatching procedure. It discussed the possible existing deadlock in the Petri Nets model of the concrete mixing and pouring procedure. Then we give out the frame of the simulator and its simulating algorithms.
