The Model of Location for Single Allocation Multimodal Hub Under Capacity Constraints

In a multimodal hub network, the limited resources at the hub may cause shipment delays which will affect the service performance. In this research, hub operations is modelled as a GI/G/1 queuing network and integrates the hub operation queuing model and the hub location-allocation model, then a multimodal hub-and-spoke hub location model considering capacity limit is proposed and tested. The results show that the model can be used to solve the location - allocation problem in the design of multimodal hub network.
