An express transportation model of hub-and-spoke network with distribution center group

Hub-and-spoke network is the main form of express transportation at present. The logistics optimization of such network is the core to get better benefits for express company. According to the transport characteristic of hub- and-spoke network, combined with hub-and-spoke theory, the express transportation model is proposed based on the lowest total transportation cost in this paper. Then the genetic algorithm for the model is given, by which we can obtain the division scheme of distribution centers and the vehicle scheduling plan. Finally, an example is solved.
