摘要:

本文总结了现有离散事件仿真的实现方法,探讨了并行处理对仿真系统的要求,提出并建立了一种基于时间Petri网的面向对象模型。在该模型中引入仿真对象并将其作为仿真处理的基本单元;引入事件发生的时间属性并将其作为时序的依据,使并行执行的事件能被正确有效地处理。此外,该方法很好地解决了仿真过程中出现的异常等问题。

Abstract:

In this paper we summarize the realization methods in discrete event simulation, discuss system requirements on how to handle parallel behaviors well.  Then it presents a timed Petri net model. In this model, a simulative object is considered the basic unit,and complex events' time-stamp is discussed,   , which is used as a proof to make parallel events be processed correctly and effectively. Additionally, the method solves exceptions well in the process of simulation

Key words: simulative object, layer, timed-Petri nets, priority queue
