摘　　要：针对生产管理模式的选择及Petri网建模规模较小等问题,根据生产物流控制的原理,在对基本制造单元进行模块化建模的基础上,应用模块化、层次化的技术构建了推式、拉式等生产管理模式的Petri网模型,然后应用参数化的技术对模型进行了改进,应用IDEF1X方法(icam definition methods,IDEF系列分析方法中的数据建模方法)对着色Petri网的颜色集进行了设计,弥补了Petri网建模的不足,并通过对这些方法的集成应用,建立了具有较强通用性的大规模复杂生产系统的Petri模型.最后,通过直接对所建Petri网模型的仿真和对仿真过程中所采集数据的统计计算,对生产系统的性能进行了分析,验证了上述建模方法的正确性和通用性.该方法为制造企业进行生产模式选择提供了有效的工具.Aiming at the option of production management model and the solution of problems such as the small scale of Petri net modeling, etc., according to the principle of production logistics control,basing on the modular modeling of the basic manufacture unit, as well as applying the modular and hierarchical techniques, the Petri net production management models of push type, pull type, etc. were built. Then the parametric technology was used to make improvement in the model, and the design of a color set of the colored Petri net was made with the application of the IDEFlX method （icam definition methods, data modeling method in IDEF series analysis method） to make up the shortcomings of Petri net modeling. The Petri model for a large scale complex production system with a stronger universality was established through the integrated application of these methods. At last, the performance of the production system is analyzed by the Petri net model＇s simulation and the statistical calculation of the data collected in the simulation process. The correctness and universality of the above modeling methods were tested and verified. The method can serve as an effective tool for manufacturing enterprises in choosing production models.
