【摘要】：针对出口箱随机入港下的分散堆放与随机选位对集装箱卡车行驶和场桥取箱作业的影响,提出了出口箱的箱区选择与箱位分配协调调度问题,并以箱区位置、箱量分配、箱位分配为决策变量,以集装箱卡车接运单位TEU平均作业时间最少、场桥作业成本最低为目标,构建了出口箱箱区选择与箱位分配两阶段非线性整数规划模型.设计了基于遗传算法的双层启发式算法,上层用于箱区搜索,确定出口箱堆放箱区及箱量分配;下层用于箱位搜寻,并依据场桥取箱顺序规则,确定具体堆放箱位或重选堆放箱区.通过算例分析结果表明:与集中入港下集中堆放相比,对出口箱随机入港下分散堆放的箱区选择与箱位分配进行协调调度同步优化,可以减少单位TEU平均装卸时间5.46%,并显著降低堆场作业成本,模型与算法可行有效.
[Abstract]:In view of the influence of the scattered stacking and random location selection of export boxes on the driving of container trucks and the loading operation of yard bridges, this paper puts forward the coordinated scheduling problem between the selection of export boxes and the allocation of boxes, and distributes the boxes according to the location of the boxes and the quantity of the containers. The box allocation is the decision variable. Taking the average operating time of the container truck transport unit as the minimum and the operation cost of the field bridge as the objective, a two-stage nonlinear integer programming model for the selection of the export box area and the box location allocation is constructed. A two-layer heuristic algorithm based on genetic algorithm is designed. The upper layer is used to search the box area, and the upper layer is used to determine the stacking area of the exit box and the allocation of the quantity of the box, and the lower layer is used for the box position search, and according to the order rule of the field bridge, Determine the specific stacking box location or re-selected stacking box area. The results show that, compared with centralized stowage under centralized port, the selection of container area and the allocation of container location under random entry of export boxes are optimized synchronously. The average loading and unloading time per unit TEU can be reduced by 5.46 and the operation cost of the yard can be significantly reduced. The model and algorithm are feasible and effective.
