基于出口箱随机到达码头的集港模式,针对后续送达的出口箱提出车船直取的装船序列优化模型.在后续送达的出口箱的到港时间与装船时间相近情况下,权衡外集卡进入码头堆场的装卸与运送成本和车船直取产生的等待成本,以车船直取比例最大为目标,对出口箱的装船序列进行优化.为进行数值试验,设计启发式求解算法,并基于锦州港的出口箱随机集港的实际观测数据进行求解计算.结果表明,针对后续送达码头的出口箱实施车船直取装船作业可以有效减少出口箱在码头堆场的费用,提高码头整体的作业效率.
Based on the port-picking model that randomly arrives at the terminal, an optimization model for the ship-by-ship loading sequence is proposed for the subsequent delivery box. When the arrival time of the export box to be delivered later is similar to the loading time, The loading and unloading cost of the truck entering the terminal yard and the waiting cost incurred by the vehicle and ship straightforward to optimize the shipment sequence of the exit box with the aim of maximizing the direct takeoff rate of the vehicle and ship.In order to carry out numerical experiments, a heuristic solution algorithm is designed, And calculated based on the actual observation data of Jinzhou Port’s export box randomized port.The results show that the direct loading and unloading of the export box for delivery dock can effectively reduce the cost of the export box in the dock yard and improve the terminal Overall operating efficiency.
