基于轴辐理论的群岛海运物流网络构建及节点选择

为了有效提升群岛海运物流运营效益,提出了一种以轴辐式网络为基础的3级海运物流网络模型;运用主成分分析法,选取对海运影响较大的7项指标,利用各岛屿的得分辅助划分群岛海运物流节点的等级;以我国南方某群岛为背景,应用该指标体系确定各岛屿的得分排序,构建了该群岛区域的3级轴辐式海运物流网络。结果表明:三级轴辐式群岛海运物流网络可以提升群岛海运物流的规模效益、节约物流成本;相应指标体系能够有效划分群岛海运物流网络的节点等级,为群岛海运物流网络的布局规划提供参考。

Archipelago shipping logistics network construction and nodes selection based on hub-spoke theory

To promote the efficiency of the archipelago shipping logistics network, a three-level model based on the hub-spoke network is put forward. Seven indices, which are analyzed by principal component analysis method, are selected to determine the level of logistics nodes in shipping logistics network. With an archipelago in the south of China as applying background, the index system is used to determine the ranking of the islands and the three-level shipping logistics network is constructed. The result shows that: the three- level shipping logistics network can promote the scale benefit and save the logistics cost; the islands in archipelago can be divided into three levels by the index system to assist the layout planning of archipelago shipping logistics network.
