垂岸式集装箱码头自动化跨运车作业任务分派与序列优化

Scheduling automated straddle carrier at automated container terminals

自动化跨运车(Automated Straddle Carrier,ASC)是一种自动化集装箱码头水平作业设备,可直接在岸桥下从地面存取集装箱,同时在堆场也可直接存取集装箱,其作业不会直接影响岸吊等其他设备的作业效率,具有独立性.考虑垂岸式集装箱堆场布局,以最小化完成时间和空驶时间为目标,建立ASC作业安排的混合整数规划模型,确定ASC的作业序列.根据数值实验结果,分析ASC数量配置的影响,以及完成时间和空驶时间之间的均衡关系.

Automated straddle carriers（ASC）is an automated horizontal operating equipment for container terminal,which independently allows direct access to containers both under the shore bridge and the yard without directly affecting the operating efficiency of quay cranes and other equipment.The present study focuses on minimizing the completion and idle time considering the vertical layout of the container yard.The mixed-integer linear program model is established to arrange the ASC operation and determine its sequence.According to the results of numerical experiments,the impact of quantity allocation of ASC is analyzed along with the equilibrium relation between the completion time and idle time.
