本文用 Petri 网的一个子类——时间事件图对流水车间型和作业车间型的柔性制造系统(FMS)建模并进行理论分析,给出了可行排序的判定条件及系统中托盘数量配置与系统生产率的关系,对系统的主要性能指标,如生产周期、工件驻留时间、在制品库存等给出了定量描述.这些结果为系统的设计和运行提供了理论依据. In this paper, a sub-category of Petri nets-time event graph is used to modeling and analyzing the flexible manufacturing system (FMS) of flowshop and job shop. The conditions of feasible sorting and the number of pallet configurations in the system System productivity, the main performance indicators of the system, such as the production cycle, the dwell time of the workpiece, the inventory of products and so on are given a quantitative description of these results provide a theoretical basis for the design and operation of the system.
