班期限制对多式联运路径决策影响研究分析

多式联运中运输时间时效性的高低直接影响到发货人、承运人和收货人的利益。在以总运输时间为目标函数的多式联运路径决策模型基础上,提出了含班期限制的多式联运路径决策模型,并根据多式联运运输网络结构特征,设计了基于遗传算法的改进算法对模型求解。算例结果表明：班期限制对多式联运路径决策有较大影响,含班期限制的多式联运路径决策模型更加合理。

Study on the limitation of schedule analysis of multimodal transport path decision

In the multimodal transport, the timeliness of transportation time directly affects the interests of the shipper, the carrier and the consignee. On the basis of multimodal transport path decision model to total transportation time as the objective function, the proposed multimodal transport path decision model with limited schedule, and according to the multimodal transport network structure design, an improved algorithm based on genetic algorithm to solve the model. Numerical results show that the schedule constraints have great influence on the multimodal transport path decision, multimodal transport path decision model with limited schedule more reasonable.
