快递超网络模型及基于成本的优化方法

Express Supernetwork Model and the Cost-Based Optimization Method

快递企业的配送网络系统由管理层和物理层网络构成,管理层网络包括了组织管理和业务管理2个不同维度的子网络,它们分别以总成本最低和效率最高为经营目标;物理层网络是一个由航空和公路配送网络组成的混合网络。因此,快递企业的配送系统具有典型的超网络特征。构建了快递网络系统的超网络模型,然后以两点间单位货物的配送成本作为物理层网络中边的权值,从组织管理的维度,探讨了基于成本的快递超网络优化方法,最后,利用算例对模型和方法的有效性进行了验证。

Supernetwork system of express enterprise consisted of management layer network and physical layer network,the management layer network was composed of organization management dimension subnetwork and business management dimension subnetwork,cost minimization and efficiency maximization were objectives of them,the physical layer network was a hybrid network which composed of highway and air delivery centers and routes,so,the supernetwork system was of characteristics of multilayer,multidimension and multicriteria.The model of express supernetwork system was discussed,a cost-based optimization method of express supernetwork was proposed in organization management dimension by regarding the delivery cost of unit freight between two delivery centers as the edge weights of them.An application case was also given to illustrate the effectiveness of the model and its optimization method in the end.
