【摘要】：针对集货高峰期集卡到达不均而导致的码头严重拥堵问题,运用排队理论和积压后移平稳估计(SBC)方法,通过同时考虑内在的码头服务能力和外在的集卡到达特征制定集卡预约策略.基于闸口、堆场集卡两阶段排队等待时间构建码头集卡预约多目标优化模型,最后用改进的NSGA-Ⅱ算法对模型进行求解.算例结果表明,所构建的模型不仅可以应对集货高峰期时集卡的预约,同时通过优化使得决策天内集卡的平均等待时间得到较大减少且有效均衡了集卡的到达.
[Abstract]:In view of the serious congestion problem caused by the uneven arrival of the loading cards in the peak loading period, the queuing theory and the method of stably estimating the backlog backward shift are used. Based on the gate gate, the multi-objective optimization model of the terminal card reservation is constructed by taking into account both the terminal service capacity and the external characteristics of card arrival. Based on the gate, the two-stage queue waiting time of the yard card is constructed for the multi-objective optimization model of the terminal card reservation. Finally, the improved NSGA- 鈪，
