基于随机Petri网的铁路货运流程优化研究
Optimization of Railway Freight Transportation Process Based on Stochastic Petri Net
【摘要】 针对电子商务平台下铁路货运业务流程存在的流程冲突、结构不合理等问题,运用业务流程理论与随机Petri网对问题进行分析和求解。采用层次化建模方法对业务流程进行模型建立与分析,找出模型中的不合理结构,应用关联矩阵重组优化规则对模型进行优化。最后以时间为参考因素,对优化前后的业务流程进行比较。实验结果表明改进后的货运流程在时间效率方面得到了明显的提升。
【Abstract】 In view of the problems of process conflict and unreasonable structure of the e-commerce-based railway freight business process,this paper analyzed and solved the existing problems using business process theory and stochastic Petri net.The top-down hierarchical modeling approach was applied to model and analyze the business processes to identify the unreasonable structure of the model.The correlation matrix regrouping optimization rules were adopted to optimize the model.Taking time as a reference factor,the business processes before and after the optimization were compared.The simulation results showed that the improved freight transport process was more time efficient than the previous one.
