摘　　要：多式联运过程中的成本涉及直接运输成本、时间惩罚成本和基于绿色发展背景下的碳排放成本,以此建立运输总成本函数模型。结合运输实际,根据对运输、时间和碳排放的不同侧重要求,对以上三种成本设置不同权重值。采用精英保留策略的混合遗传算法进行模型求解,分别得出三种成本不同权重下的多式联运路径选择和成本构成情况。经分析比较,在综合均衡考虑运输成本、时间成本和碳排放成本时,路径优化更合理,多式联运总成本更低,为多式联运参与者在路线选择和各项成本的权衡方面提供参考。The cost of multimodal transport involves direct transport cost,time penalty cost and carbon emission cost under the background of green development.According to the different requirements of transportation,time and carbon emission,different weight values are set for the above three costs.Hybrid genetic algorithm(HGA)with elite reservation strategy is used to solve the model,and the multimodal transportation path selection and cost structure under three different cost weights are obtained.After analysis and comparison,when the transportation cost,time cost and carbon emission cost are considered,the path optimization is more reasonable and the total cost of multimodal transport is lower,to provide reference for multimodal transport participants in route selection and trade-offs of various costs.
