Express Supernetwork Model and the Cost-Based Optimization Method

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.
