The allocation of yard spaces in container transshipment ports differs significantly from that in traditional container ports. In this study, we examined the yard space allocation problem specific to container transshipment ports with mother and feeder vessels. Following an in-depth analysis of container stacking patterns for these vessel types, we propose a yard space sharing strategy called the “sub-block with two services” approach. Subsequently, we develop a mixed-integer programming model tailored to optimize yard space allocation within container transshipment ports. The primary objective of this model is to enhance yard space utilization while concurrently minimizing container transportation distances. To improve the efficiency of the proposed model, we employed a range of optimization methods and established an effective upper bound for solution quality. Finally, we draw on our experimental findings and consider the practicality of container terminal operations to provide insightful recommendations for managing container transshipment ports with mother and feeder vessels.

母船和支线集装箱转运港堆场空间分配

集装箱转运港堆场的配置与传统集装箱港口有很大不同。在本研究中，我们研究了母船和支线船舶的集装箱转运港口特有的堆场空间分配问题。在深入分析这些船舶类型的集装箱堆放模式后，我们提出了一种称为“具有两种服务的子区块”方法的堆场空间共享策略。随后，我们开发了一个混合整数编程模型，专门用于优化集装箱转运港口内的堆场空间分配。该模型的主要目标是提高堆场空间利用率，同时最大限度地减少集装箱运输距离。为了提高所提出模型的效率，我们采用了一系列优化方法并建立了解决方案质量的有效上限。最后，我们利用实验结果并考虑集装箱码头运营的实用性，为管理母船和支线船舶的集装箱转运港口提供富有洞察力的建议。
