| 摘 要： | 为了保证所设计的机械制造系统(MMS)能够获得最大的经济效益,必须对系统进行合理的规划设计。本文首先引入MMS规则设计中的几点原则,以及计算机仿真涉及到的生产调度问题及其决策规则,论述各生产调度规则在Petri网模型中的实现方法。并对Petri网运行中的冲突问题引入了解决冲突的规则。其次,基于包括工件流和刀具流的MMS的Petri网模型,根据最小事件时间推进原理,实现Petri网模型的计算机动态仿真,即实现MMS的计算机动态仿真。最后,将仿真程序应用于仿真实例,从而有效地评价MMS的规划设计方案。

| Abstract: | Planning design is to work out a more overall long-term plan. In order to guarantee a Mechanical Manufacturing System (MMS) designed to obtain maximum economical benefit, it is necessary to carry out reasonable planning design for the system.Firstly, some principles on planning design for MMS are introduced in this paper. Problems of production scheduling and their decision rules for computer simulation are also presented. Realizable method of each production scheduling decision rule in Petri net model is discussed. Secondly, the solution of conflict rules for conflict problems during running Petri net is given. Thirdly, based on the Petri net model of MMS which includes part flow and tool flow,according to the principle of minimum event time advance, a computer dynamic simulation of the petri net model that is, a computer dynamic simulation of MMS is realized. Finally, the simulation program is applied to a simulation example, so the scheme of a planning design for MMS can be evaluated effectively. |
