离散事件系统仿真建模与仿真策略

离散事件系统仿真是现代仿真技术的主要研究热点之一．离散事件系统是一类在工程技术、经济、军事等领域常见的系统，它们的状态在一些不均匀的离散时刻发生变换且状态变换的内部机制比较复杂，往往无法用常规的数学方法来描述．离散事件系统仿真是当前研究这一类系统的最有用处的方法之一．要对系统进行仿真研究，首先需要建立系统的仿真模型．笔者比较详细地探讨了离散事件系统仿真建模的核心一仿真流程管理、离散事件系统的三种仿真建模策略，即：事件调度法、活动扫描法、进程交互法．

Simulation Modeling and Simulation Diplomacy of Discrete Event System

Discrete event system simulation is one of the important field of modern simulation. There are many discrete event system in engineering, economic and military field, the change of their state occurs on some discrete time, change mechanism of system state is very complex, can not be described by using mathematic method. Discrete event system simulation is one of the effective approach of study these systems. It is needed to build the simulation model of system to simulate the system, in this article, the authors bring the concept of discrete event system simulation into focus, then study the kernel of simulation modeling of discrete event system-management of simulation process, three kimds of simulation modeling diplomacy: Event Scheduling, Activity Scanning, Process Interaction.
