中文摘要：

为优化同城快递网络,用度数中心度、中间中心度和接近中心度来分析同城快递配送中心选址问题,综合体现网点在整个网络中的位置、其他网点的依赖性和桥接的重要性。利用变异系数法来确定三个中心度的权重并建立模型来进行同城快递网络结构的综合评价。以X快递公司在杭州市辖区的快递网络为例,利用UCINE软件建立关系矩阵得出每个网点的中心度数据,结合实际情况进行分析,最终得出同城配送中心选址的方案,根据评价模型计算得知,快递网点的桥接作用和资源控制度比位置更为重要。

英文摘要：

To optimize the city-wide express network, the paper uses the degree centrality, the betweenness centrality and the closeness centrality to analyze the location selection problem of the city-wide express distribution center. It is a comprehensive method to reflect the position of outlets in the whole network, dependence of other outlets and the importance of the bridging effect. The paper determines the weight of three centralities by using the variation coefficient method and establishes a comprehensive evaluation model for city-wide express network structure. This paper carries out a case study of express network of X express company in Hangzhou. UCINE software is applied to establish relationship matrix and to gain centrality data of each outlet. By analysis in combination of actual conditions, the location selection scheme about the city-wide distribution center is finally obtained. It is known from evaluation model calculation that, the bridging effect of express outlets and resource control are more important than the location.
