基于时间Petri网的生鲜肉冷链物流流程建模研究

摘要

In this paper, we used the temporal Petri nets theory to model the process of cold-chain logistics and studied its operational efficiency. Then we ran the model established on the CPN platform and obtained the performance indicators of the various links, found the inadequacy in the process and proposed the suggestion for its improvement.%以生鲜肉冷链物流为例,应用时间Petri网理论对冷链物流流程建模,研究冷链物流运作效率.用CPN tools对建立的模型运行后得到各环节的性能指标,发现流程中所存在的不足.最后提出对流程的改进建议.建模方法对复杂的冷链物流流程的建模和仿真有一定的参考价值,并为冷链物流以后的优化研究提供了新的思路.
