摘　　要：以合理配置和优化内外资源为目的的生产调度问题已成为制造业的研究热点。通过利用赋时Petri网建模方法对JobShop生产调度问题建立模型,采用Matlab环境下的Stateflow工具箱实现了对所建Petri网模型的动态可视化仿真,获得了网运行的变迁序列并构建出Petri网的可达图,同时分析了各机器生产效率。该仿真方法降低了Petri网理论分析的难度,仿真结果为制造系统的实际流程设计提供了依据。To configure and optimize internal and external resources has become a research focus in the manufacturing sector for the purpose of the production scheduling. After the use of Timed Petri Net modeling for Job Shop Production Scheduling, the stateflow toolbox in the Maflab environment was used to realize a dynamic visual simulation of the net, gained the transition sequences and reachablility graph of the Petri net, and analyzed the productivity of each machine. This methodreduces the difficulty of the analysis of Petri net theory and also provides a basis for the workflow design of manufacturing systems.
