针对具有岸桥间不可相互穿越及安全距离约束、甲板开闭约束的集装箱码头岸桥混合装卸作业的调度优化问题,分析了岸桥装卸与移动过程中的相关性质,并提出一种基于减小岸桥移动距离和均匀化岸桥负荷的启发式算法.在该算法基础上设计了一种遗传算法,进一步搜索最优解,并推导了问题的一个低界.数据实验表明,所提出算法的解具有良好的质量和较高的时间效率.
The quay crane scheduling problem studied in this paper is to determine an assignment and a(handling) sequence of bays for quay cranes,considering the interference between quay cranes and the deck(constraints.) A mixed integer programming is proposed and some properties of the problem are deduced.A genetic algorithm is designed to obtain the near optimal solutions.A lowerbound is given to evaluate the effectiveness of the proposed algorithm.Computational experiments are conducted and it is shown that the proposed algorithm is effective and efficient in solving the problem.
