Abstract

In order to shorten the total time of the ships in port at a planning horizon, an integrated optimization method for berth schedule and quay crane allocation was developed. Interrelation between berth and quay crane allocation was analyzed, sharing quay cranes with the adjacent berths was put forward, dynamically allocating the limited quay cranes in the scheduling of handling tasks on each ship, an integer mathematical planning model was set up, and a corresponding genetic algorithm was designed to solve the problem. The result suggests that the method can improve container handling efficiency effectively compared with that of separate allocation.
