【摘要】：针对出口箱随机入港分散堆放对码头装卸作业系统泊位分配、集卡路径与箱区选择的影响,分析了甲板箱与舱内箱的不同装卸特点。以船舶停靠泊位和进口箱堆放箱区为决策变量,以集卡行驶距离最短为目标函数,构建了离散泊位状况下泊位-集卡-箱区协调调度混合整数规划模型。通过三层依次交叉,开发了基于遗传算法的三层启发式算法,上层搜索泊位数据,中间层搜索船舶数据,下层搜索进口箱箱区数据,并进行实例验证。计算结果表明:与传统方法相比,应用离散泊位下泊位-集卡-箱区协调调度混合整数规划模型可以同步确定最优的船舶停靠泊位、进口箱堆放箱区、集卡行驶路径,集卡行驶总距离缩短11.42%,码头装卸作业系统效率明显提高。可见,提出的模型有效。
[Abstract]:In view of the influence of random loading and unloading of export boxes on berth allocation, card collection path and box area selection of terminal handling system, The different loading and unloading characteristics of deck tank and tank are analyzed. The berthing berth and the loading area of inlet container are taken as decision variables, and the shortest travel distance of collecting card is taken as the objective function. The mixed integer programming model of berth, card-box area coordination scheduling under the condition of discrete berth is constructed. By crossing three layers in turn, a three-layer heuristic algorithm based on genetic algorithm is developed to search berth data in upper layer and ship data in middle layer. The lower layer searches the data of the inlet box and verifies it by an example. The result of calculation shows that compared with the traditional method, By using the mixed integer programming model of coordination scheduling between berth, card-box area and berth under discrete berth, the optimal berth of ship can be determined synchronously, and the berth, the stowage area of import box, and the path of card-collecting can be determined synchronously. The total distance of card driving is shortened by 11.42 and the efficiency of loading and unloading system of wharf is improved obviously.
