Abstract

This study investigates a problem regarding simultaneous allocations of berths, quay cranes, and yards in transshipment hubs. Transshipment and import/export activities, general quay crane assignment decisions, and productivity losses incurred by quay crane interference are considered. A mixed-integer programming model is proposed to minimize the total cost, including speed-up cost, delay cost, penalty cost of vessels, and operational cost on container loading and unloading. An iterative heuristic is developed to solve the proposed model. Extensive numerical experiments are conducted to validate the effectiveness of the proposed model and the efficiency of the algorithm.
