Abstract

Container port operation is essential for the vessel's turnaround time. This paper studies the synchronous loading operation of quay cranes and straddle carriers, considering various practical constraints. A mathematical model is proposed in a flexible container operation sequence by minimising the sum of the quay crane completion time and the straddle carrier waiting time. To solve the problem studied, a two-stage algorithm is designed based on greedy strategy and dynamic adjustment. Various experiments are conducted to verify the performance of the proposed solution method. The experimental results show that the two-stage algorithm has a better solution performance on small and medium-sized problems. Finally, the sensitivity analysis is conducted.
