针对柔性制造系统（ＦＭＳ）实时生产过程仿真的特点与需要，本文在分析仿真原理与结构的基础上，以Ｐｅｔｒｉ网为模型工具，重点探讨了ＦＭＳ实时生产过程仿真中的数据组织、模型分解及描述，以及托肯管理等典型问题，并提出相应的解决思路和处理方法。最后，通过实际ＳＪ－ＦＭＳ系统的仿真运行，验证了所提出的仿真思想及实现仿真的具体方法。 Aiming at the characteristics and needs of FMS real-time production process simulation, based on the analysis of simulation principle and structure, this paper takes Petri net as a model tool and focuses on the data organization and model decomposition of FMS real-time production process simulation. Description, and the typical problems of trust management, and put forward corresponding solutions and methods. Finally, through the simulation of actual SJ-FMS system, the proposed simulation ideas and the specific methods of simulation are verified.
