为了提高码头的作业效率,保证到港船只能在最短的时间内完成作业,建立了全泊位岸桥调度模型。在岸桥的可移动范围内,为了降低岸桥的闲置时间,提高利用率,一个贝位可由多台桥吊交替进行作业。根据宁波港码头实际的操作情况,设计了一种钻孔作业的启发式算法,将箱量较多的重点贝位的操作进行优先考虑。然后,岸桥再根据贝位的平均作业量进行分配作业,确保船只作业在最短的时间内完成。计算结果表明:船只能够在计划时间内完成作业,甚至能改善不准时到港船只造成的时间延迟所产生的不良后果。
In order to improve the efficiency of the terminal and make sure that ships can complete the homework in the shortest time, quay cranes scheduling model of the berth is presented. In order to reduce the idle time and improve the utilization ratio of the cranes, the scope. According to the actual operation situation of considers the most important bay first , and then do to ensure that the ships can complete the homework bay can be handled by many sets of cranes port, a heuristic algorithm of drilling which move in its is designed, which other jobs according to the bay' s average production. In order in the shortest time. The calculation results show that the ships can finish the homework in the plan time and even can improve the adverse consequences caused by the delay of the boats.
