| 摘 要： | 以多式联运货运网络为研究对象,综合考虑轴辐式网络中的规模效应、运输成本、时间及运输能力限制,构建多式联运货运网络模型。基于龙潭港货物运输实际,利用遗传算法对龙潭港多式联运枢纽网络优化模型进行求解,特别针对南京集疏运通道建设前后,分别运用模型求解,对南京联运方式变化进行对比分析,证明了在发展集疏运通道建设后,南京在运输网络中的地位进一步得到提高。

| Abstract: | In this paper,with the multimodal freight transportation network as the research object,we considered comprehensively the scale effect,transportation cost,time and transportation capacity restrictions in the hub-and-spoke transportation network,and constructed a multimodal freight transportation network model.Next,based on the freight transportation practice of Longtan Port,we used the genetic algorithm to solve the optimization model of the Longtan Port multimodal transport hub network.At the end,focusing especially on the difference before and after the construction of the Nanjing consolidation and distribution channels,we looked into the changes in the intermodal transportation modes of Nanjing and proved that,after the development of the consolidation and distribution channels,Nanjing's position in the transportation network has been further raised. |
