多式联运分运人选择的模型和算法

在对多式联运分运人选择问题分析的基础上,运用图论技术构建了基于联运分运人选择的多式联运网络。综合考虑了运输的规模经济性、时效性、风险性和联运联盟的稳定性,建立了基于综合运输成本最小、运输风险最小和合作强度最大的多目标优化选择模型。通过主要目标法,将模型转化为单目标模型。借鉴生物免疫原理,设计了基于克隆增扩的人工免疫算法对问题进行求解。最后通过算例对方法进行了验证。

Optimization Model and Algorithm for Intermodal Carrier Selection in Various Sections

This study focuses on one of the intermodal operational problems:how to select the appropriate carrier for shipment through the intermodal network.In this paper,five important characteristics,i.e.multiple objective,in-time transportation,combined cost,transportation risks and collaboration efficiency are taken into consideration.Based on the graph-theory technique,an improved intermodal network is established,and a multiobjective model is then formulated.Furthermore,the multiobjective model is transformed i...
