In the case of new hub terminal construction or joint use of hub terminals through partnerships between courier companies for terminal capacity expansion, the hub terminal is physically composed of several terminals. In this situation, incoming trucks departing from sub-terminals arrive at the hub terminal, the parcels are unloaded, classified by destination within the hub terminal, moved to the departure dock, and loaded outgoing trucks, and finally outgoing trucks go to the destination sub-terminal. However, there is a mixture of volumes with different destinations in the incoming truck, and in each hub terminal an exit dock is classified for each destination. If the parcel is unloaded at a hub terminal and there is no remaining space in exit dock corresponding to the destination in that terminal, the parcel has to move to another hub terminal with destination departure dock. The movement of parcels between hub terminals is much more expensive than the movement of parcels for sorting within the terminals and increases the work time and work load in the process of repeating loading and unloading operations. So It is very important to minimize the movement of parcels between hub terminals. In a situation where the capacity and time that can be handled per day is limited at the hub terminal, minimizing the truck"s travel distance between hub terminals to reduce costs and time as much as possible plays a critical role in improving terminal operation efficiency. In this study, we present a mathematical model for the problem of determining which hub terminal to assign incoming trucks arriving from each sub-terminal and from which hub terminal to get to the destination sub-terminal, develop a solution method, and derive an optimal solution using numerical examples.
