Multi-Period Inland Depot for Empty Container Expansion Problem

The trade imbalance in the U.S. where there is a greater percentage of imports than exports require a constant repositioning of empty containers. These regional movements create unproductive and unnecessary empty truck tips that contribute to highway congestion, traffic safety and urban emissions. This paper proposes a mixed-integer programming model for the empty container allocation problem with consideration of existing terminal expansion, level of street turns and multiple periods for decision making. In each period, the objective is to determine the location of new empty container depot(s) and amount of capacity to expand at existing depots with a given budget for the period. The proposed model is tested on a 15-node hypothetical network with different levels of street-turns. Results indicate that when depot owners have sufficient budget to spend and more flexibility in terms of being able to shift their budget between decision making periods, the greater the percentage of empty vehicle miles they can reduce at the regional level. Establishing new container depots are found unnecessary when there is a higher level of street-turns.
