摘要
离岸集装箱码头因其岛屿面积限制,难以通过扩建码头内部堆场增加吞吐能力。为解决这个问题,提出一种离岸集装箱码头新装卸工艺模式。新装卸工艺模式是通过在离岸集装箱码头附近的陆域地带建设陆域集疏运堆场,与离岸集装箱码头进行协同装卸作业的模式。陆域集疏运堆场堆存空间分配的目标是满足离岸集装箱码头装卸作业预翻倒要求;单批次输送集装箱的量受到陆岛运输最大通行能力限制。根据上述目标与特点,构建新装卸工艺模式下陆域集疏运堆场堆存空间分配模型,并设计蒙特卡洛树搜索算法进行求解。通过算例分析验证模型的有效性。结果表明该方法能够满足陆域集疏运堆场堆存空间分配需求并提高离岸集装箱码头的吞吐能力。
It is difficult to increase the throughput capacity by expanding the internal yard in an offshore container terminal due to the limitation of island area.A new handling technology mode of offshore container terminals is proposed to solve the problem.The new mode of handling technology is to build a collection and distribution yard near the landside area of an offshore container terminal for collaborative loading and unloading with the offshore container terminal.The storage space allocation target of the landside collection and distribution yard is to meet the requirements of pre-reshuffle demand of the offshore container terminal;the traffic volume of single batch of containers is limited by the maximum capacity of land-island transportation.According to the above objectives and characteristics,the storage space allocation model of the landside collection and distribution yard under the new handling technology mode is constructed,and the Monte Carlo tree search algorithm is designed to solve the model.The effectiveness of the model is verified by numerical experiments.The result shows that the proposed method can meet the demand of storage space allocation of a landside collection and distribution yard and can increase the throughput capacity of an offshore container terminal.
