摘　　要：分析了传统随机制造单元Petri网模型能的不足,对传统随机制造单元的Petri网模型进行了改进。通过对Petri模型的直接仿真,对不同的Petri网模型的随机制造单元的性能指标进行了分析比较,并通过和同构的马尔可夫链的计算结果进行验证,证明了改进后的Petri网模型准确地描述随机制造单元,对基于仿真的性能分析方法具有普遍意义。This paper analysed the deficiency of Petri net model of traditional stochastic manufacturing unit, and proposed an improved Petri net model to deal with the situation. It simulated improved Petri net models of different stochastic manufacturing units directly and conducted performance analyses. Moreover, it verified the capability of improved Petri net to depict stochas- tic manufacturing units accurately by comparing with the calculation results of Markov chain based on the same structure. The methodology of performance analysis based on simulation is universal significance.
