基于Petri网的冷链配送流程仿真优化研究

应用Petri网理论．对冷链配送流程进行优化研究。根据某企业目前的配送流程，利用Petri网理论进行建模。之后运用ExSpect软件对模型进行了仿真。得到仿真结果后，对结果进行分析，并基于效率提高和流程重构两种优化措施对流程进行改进。最后．再次利用软件对改进后的流程进行仿真，说明改进措施的有效性，并增加了随机性仿真，加强仿真结果的可信度。

Research on the Cold Chain Distribution Process Simulation and Optimization Based on Petri Net

This paper researches on simulation and optimiza- tion of cold chain distribution process based on Petri net. Af-ter describing present situation of the distribution process, this paper builds a Petri net model of the distribution process and then simulates the Petri net mode with the software of ExSpect. After getting the simulation results, this paper describes how to optimize the distribution process through improving efficiency and process reengineering. In the end, the author simulates the new process ...
