摘要
制造业的生产物流方式处于不断变革中,对其建模仿真可为制造系统规划设计、分析及改造提供决策支持。依“人-机-物-环-法”分类给出了智能车间制造系统中实体元素的描述,结合EFSM(extended finite state machine)和组件化建模思想,建立了生产和物流组件化EFSM模型;阐述了智能车间多作业生产的建模过程以及组件模型实例化方法;通过EFSM-DEVS(discrete event system specification)模型自动转换及DEVS引擎完成了仿真运行。仿真结果表明:该方法所建立的模型更符合车间实际状况,适用性更广;组件化建模思想能构造更具扩展性的软件;建模及仿真运行的3D可视化使软件直观性更好,其仿真结果与AnyLogic保持一致。
The production logistics mode of manufacturing industry is developing rapidly,on which the modeling and simulation can provide the decision support for the design,analysis and transformation of manufacturing system.A description of the entity elements in intelligent workshop manufacturing system is given according to the classification of"human machine material environment rule".A production and logistics componentized EFSM model is created on the basis of EFSM and componentized modeling ideas.The modeling process for multi-job production in smart shop and the component model instantiation methodology are elaborated.The simulation running through the automatic conversion of EFSM-DEVS model and DEVS engine is completed.The simulation results show that the model established by this method is more in line with the actual situation of the workshop and is more applicable.The idea of component modeling can construct the more scalable software;Modeling and the simulation running of 3D visualization makes the software more intuitive,and the simulation results are consistent with AnyLogic.
