针对快递服务网络规划问题中的两类网络物理结构形态的优劣评估问题,在动态环境下分析了网络结构变化的影响因素及其演变趋势,发现网络节点城市之间业务量的大小对于基于集中规模经济效应的轴辐式网络的成本节约优势是否成立有主要影响。这说明纯轴辐式与全连通这两个网络结构并不存在必然的优劣之分,各自的成本节约优势取决于所有城市之间业务量等参数的变化。最后结合国内有关标杆企业的数据,对长三角区域的快递服务网络结构演变趋势进行了实例分析,结果验证了所得出的结论。
As for the appraisal of the two topological structures of the express network design, this paper analyses the influencing factors and evolution tendency of the network structure and discovers that the volume between cities is the key factor to determine whether HS network can produce cost saving. This discovery illustrates that there is no absolute distinct between the pure HS and full-connected networks and the cost saving advantages depends on the volume and other parameters ' change. Finally, combining with the data from the benchmarking enterprises, the paper verifies the conclusion by empirical analysis of the evolution tendency of the express network structure in Yangtze River Delta Region.
