Optimization of Hub-and-Spoke Two-stage Logistics Network in Regional Port Cluster

To optimize two-stage logistics transportation network in regional port cluster, combining hub-and-spoke transportation system among regional port with consolidation and dispersing transportation systems between ports and their own hinterlands, a nonlinear optimization model for two-stage logistics system in regional port cluster is introduced to simultaneously determine the following factors: the hinterlands serviced by individual ports and transportation capacity operated between each port and its hinterland, cargo transportation volume and corresponding transportation capacity allocated via a hub port from an original port to a destination port, cargo transportation volume and corresponding transportation capacity allocated directly from an original port to a destination port. Finally, a numerical example is given to demonstrate the application of the proposed model. It can be shown that the solution to the proposed non-linear model can be obtained by transforming it into linear programming models.
