近年来，随着我国铁路事业的迅猛进展，铁路的运输能力得到了大幅度提升。在客运技术与速度提高的同时，作为旅客体验铁路服务的一个必要环节，售票环节的重要性也随之提高。然而大型客运站真实的售票过程极为复杂，旅客的行为受事件驱动，他们的状态在一些不均匀的离散时刻发生改变且其变化的内部 机理非常复杂，离散时间点一般不能确定，这是典型的离散事件系统，通常无法利用一般的数学方法进行描述。我们通常采纳离散事件系统仿真的方法来解决此类问题，它是解决此类问题的最有用处的方法之一。要对系统进行仿真讨论，首先就必须建立起系统的仿真模型。本文在阅读大量文献的基础上，简单介绍了离散事件系统的建模与仿真方法，并对北京西客站售票大厅建立离散事件系统仿真模型，对旅客售票过程进行了优化改善。关键词：离散事件,系统仿真AbstractIn recent years, with the rapid development of China's railway business, railway transport capacity has been improved significantly. The process of Buy a ticket became more and more important , while the technology and speed had SubstantiallyImproved.But the process in the real world is so complex that we can not useMathematical methods to study it. The most useful way to study this case is to Simulate the Discrete Event System. Simulation study of a system, we must first establish a system simulation model. On the base of studying a lot of academic articles this thesis simplely introduced the discrete event systems modeling and simulation methods and established the discrete event systems of Beijing West Railway Station. Simulated and optimizated the process of Buy a ticket KEYWORDS：discreteevent,systemsimulation.精品文档---下载后可任意编辑1.概述 41.1.售票服务环节讨论 21.2.离散事件系统 21.3.离散事件系统仿真讨论现状 31.3.1.离散事件系统建模 31.3.2.离散事件系统仿真 31.3.3.离散事件系统仿真数据分析 32.离散事件系统建模与仿真介绍 32.1.基本概念 32.1.1.实体（Entity）32.1.2.属性（Attribute）42.1.3.状态（State）42.1.4.事件(Event)42.1.5.活动(Activity)42.1.6.进...
