Abstract: A mathematical model for gantry crane' s retrieving operation was established to minimize the re-handling number in the whole retrieving operation process in a bay. And then the mathematical model was solved by the heuristic algorithm based on six principles of choosing location. Different scales of initial bay states were generated randomly and simulation experiments were conducted by using the heuristic algorithm programmed by MATLAB. The result was compared with the one using by dynamic programming. It is concluded that the heuristic algorithm is the better, stable and feasible solution and it improves the efficiency of retrieving operation and fulfills the timeliness of work in container port.

Key words: container port, yard, retrieving operation, re-handling, heuristic algorithm

摘要: 以龙门吊起重机在贝位内取箱作业过程中倒箱量最少为目标,建立龙门吊起重机取箱作业数学模型;再应用 基于6 条倒箱落位原则的启发式算法对数学模型进行求解;随机生成不同规模的初始贝位状态,使用MATLAB 编 译的启发式算法进行仿真实验,将得到的较优解与动态规划所得的最优解进行比较;经验证,启发式算法可获得较 优的可行解,稳定性强,提高了取箱作业的效率,符合码头作业的时效性。
