在混堆装船箱区中,提箱外集卡抵达时序的随机性增加了装船过程中的倒箱作业量,增大了堆场中场桥调度的难度,降低了堆场作业效率.针对该问题,重点考虑了内外集卡不同的优先级别、作业截止时刻和作业过程中倒箱量的影响,建立了以港方费用、作业过程中倒箱量两者最小为双目标的混堆装船箱区多场桥调度的数学模型.提出了一个带有滚动时域的启发式求解算法,并且为求解单个时域对应的子调度问题,设计了一个带有解空间切割功能并嵌入倒箱策略的遗传算法.通过仿真算例,验证了优化模型及算法的实用性与有效性.本文可以为实时的场桥调度提供决策支持. In the mixed stacking loading area, the randomness of the arrival timing of the outer stacking card increases the number of down-loading operations in the loading process, which increases the difficulty of the mid-market bridge scheduling and reduces the working efficiency of the yard. The problem, with emphasis on the different priorities of the internal and external collection cards, the operation deadline and the impact of the amount of cartons in the process of operation, the establishment of a Hong Kong-side costs, A mathematic model of multi-field bridge scheduling in the bridge area is proposed. A heuristic solution algorithm with rolling time-domain is proposed. To solve the sub-scheduling problem in a single time domain, Strategy genetic algorithm.The simulation example is used to verify the practicability and effectiveness of the optimization model and algorithm.This paper can provide decision support for real-time field bridge scheduling.
