无水港-海港系统集装箱运输网络优化模型

摘要

Under the background of hinterland sharing, the construction of dry port represents an important means to develop harbor hinterland. Based on the analysis of network characteristics of dry port-harbor system, the dry port-harbor transportation network optimization model is established for the optimal objective function of the total cost. Through the solution and analysis of model by LINGO software, the location and layout problems of dry port-harbor network was settled. The construction of dry port can effectively reduce the cost of container transportation from hinterland to harbor, and the reduction in costs is associated with the number of dry ports, which can help to establish a dry port-harbor system with high efficiency and low cost.%在腹地共享化的背景下,无水港的建设成为海港腹地拓展的重要手段.在分析无水港-海港网络特性的基础上,以无水港-海港系统总成本最优为目标函数,构建无水港-海港运输网络优化模型,并使用LINGO软件对模型进行求解分析,可以解决无水港-海港的网络选址布局问题.无水港的建立有效的降低了从腹地到海港的集装箱运输成本,而成本的减少程度与无水港的建设数目相关,对无水港的合理布局有利于整个无水港-海港系统高效低成本运行.
