The present dissertation mainly studies the supervisory control of des , namely , how to design a controller for a des plant such that its closed - loop behaviors satisfying a desirable specification 人们研究离散事件系统主要有两个任务：一是提供分析和评估系统的技术；二是提供控制系统运行的方法(即监控理论) 。
By understanding and realizing the system that is on studying , the the discrete event system simulation taking out some key parameters from the system , establishing simulation model resemble to realistic system 离散事件系统仿真是通过对所研究系统的认识和了解，抽取其中基本要素的关键参数，建立与现实系统相对应的仿真模型。
In this paper , a control method for discrete event systems ( des ) based on colored petri nets is proposed . the constrains with the forms of or - logic are enforced and all of the transitions in the net are permitted to be concurrent 本文提出的利用有色petri网控制离散事件系统的方法，不但实现了或逻辑形式的约束，而且允许petri网中的所有变迁都可以并发。
Based on automatic machint model and formal language , the state feedback control of concurrent discrete event systems is introduced . necessary and sufficient conditions for the existence of a controller are shown to achieve a prescribed behavior 以自动机为模型，利用形式语言讨论了并发事件存在的情况下，矢量离散事件系统的非确定状态反馈控制，对所得结论给出了证明。
Due to the rapid development of computer science and its extensively application in modern society , some scholars found a new type of dynamic systems named as discrete event systems ( des ) , which is different from continuous variable dynamic systems 现代计算机科学的迅猛发展及其在现代社会中广泛的应用，催生了一类不同于连续变量动态系统的新系统，学者们将之命名为离散事件系统。
This dissertation has researched on applying the recently developed discrete event system ( des ) theory to analyze the testability of the mixed - signal circuits and provided a systemic method for the digital circuits and the analog circuits 本文运用离散事件系统理论( discreteeventsystem , des )来进行数模混合电路的可测试性分析，提供了一种对数字电路、模拟电路及数模混合电路测试统一的处理方法。
We are based on the reasearching discrete effect system computer simulation , design a software for work - flow manufacture system . this software is tested for cylinder body product line of dalian diesel oil machine factory . we acquire satisfactory result 我们在研究离散事件系统计算机仿真的基础上，设计了一套专用于流水线制造系统仿真软件，该软件对大连柴油机厂的气缸体生产线进行了仿真测试，取得了满意的结果。
Based on analyzing various kinds of simulation languages appearing on the market now , the paper uses discrete event system theories and methods of simulation to program the procedure of the jobshop problem of forestry enterprises by applying the visual basic language 本文在综合分析了现有各种仿真语言的基础上，应用离散事件系统仿真的基本理论和方法，利用visualbasic语言对林业企业中的加工问题进行了仿真程序设计。
Third , the traditional method of the establishment of disperse systems is analyzed ; the method of step establishment model is used . this method makes the establishment of disperse systems easy , and can minish the complex of makes the establishment of disperse systems 再次,分析了离散事件系统的建模方法,提出了对象模块化分级建模方法,该方法分三步对柔性制造系统建模:建立系统的静态对像模型、动态行为模型和调度决策模型。
In the port , the ships passes in and out the harbor demand tugboat drag , the ships passes in and out the harbor event is a typical dess ( all the ships size , the ship tonnage , the time of ship passes in and out the harbor are random ) , which will bring the certain difficulty to reasonable marshaling for ship team 在港口，船舶进出港需要拖轮拖引，船舶的进出港事件是一个典型离散事件系统(船舶大小、载重吨及进出港时间均是随机的) ，这为船队合理配置拖轮带来一定的难度。
