摘要

背景:集装箱码头的关键性能指标是船舶停泊时间,这在很大程度上受到不同装卸设备调度的影响。装卸设备的适当综合调度至关重要,尤其是在自动化集装箱码头,所有装卸设备都是自动化的,必须进行协调以避免干扰。学者和码头运营商面临的最具挑战性的问题之一是,考虑到双小车码头起重机(QC)的缓冲能力和进口集装箱的有限存储位置,为不同的设备引入适当的调度计划。方法:考虑到双小车QC下有限的缓冲能力和进口集装箱的储存分配,提出了一个数学模型来集成自动堆场起重机和自动导引车的调度。结果:通过求解不同的实例来评估所提出的模型的性能,并研究使用双小车QC而不是单小车QC的影响,以及使用不同缓冲容量的影响。结论:结果表明,该模型除了为YC和AGV分配进口集装箱外,还提供了详细的调度和分配计划。此外,与单小车QC相比,双小车QC可以显著缩短完成时间并提高AGV的利用率。

Integrated Scheduling of Automated Yard Cranes and Automated Guided Vehicles with Limited Buffer Capacity of Dual-Trolley Quay Cranes in Automated Container Terminals
Background: The key performance index for the container terminals is the vessel berthing time which is highly affected by the scheduling of the different handling equipment. Proper integrated scheduling of the handling equipment is crucial, especially in automated container terminals, where all the handling equipment is automated and must be coordinated to avoid interference. One of the most challenging problems both scholars and terminal operators face is introducing a proper scheduling plan for different equipment, considering the buffer capacity of dual-trolley quay cranes (QCs) and the limited storage locations of import containers. Methods: A mathematical model is proposed to integrate the scheduling of automated yard cranes and automated guided vehicles (AGVs), considering the limited buffer capacity beneath dual-trolley QCs and the storage allocation of import containers. Results: different instances were solved to evaluate the proposed model’s performance and investigate the impact of using dual-trolley QCs instead of single-trolley QCs, and the impact of using different buffer capacities. Conclusions: The results show that the model provides detailed scheduling and assigning plans for the YCs and AGVs besides allocating import containers. Additionally, the dual-trolley QCs can significantly decrease the completion time and increase AGVs’ utilization compared to the single-trolley QCs.
