摘要: 为了优化集装箱堆场空间资源, 减少集卡行驶距离, 运用数学规划方法, 从平衡箱区倍位箱量和最小化集卡行驶距离入手, 在滚动计划的基础上, 建立了集装箱堆场空间资源动态配置模型。与集装箱随机配置模型相比, 发现集装箱在动态模型配置下, 可使集卡行驶距离减少20%左右, 提高了集卡使用效率, 降低了集装箱作业成本。Abstract: In order to optimize the space of container storage yard and reduce vehicle travel distance, mathematics planning method was applied, the balancing quantity of container and the minimum travel distance of vehicle were considered, a dynamic space deployment model of container storage yard was set up on the base of rolling plan, and the example comparison analysis of the model and random deployment method was done. Analysis result shows that vehicle travel distance decreases by about 20%, vehicle travel efficiency improves, and container operating cost reduces, so the model is feasible.
