Abstract

The rising growth of the global economy along with maritime trade prosperity highlight the resilience of this industry despite challenges. Seaports, as prominent hubs of the international supply chain, handle approximately 80 % of global freight volume which necessitates the efficient planning and scheduling of operations. This study addresses the functional and deep integrated planning of the berth allocation problem (BAP), quay crane assignment problem (QCAP), and quay crane scheduling problem (QCSP). Also, a novel algorithm for scheduling the QCs within the deep integrated scheme was developed. A comprehensive comparison of integration approaches for the three problems’ MILP model was proposed utilizing hybrid solution algorithms with Particle Swarm Optimization (PSO) and Dynamic Programming (DP) methods. The objective functions aimed at minimizing the costs of berth position deviation from the best berth location, deviation of end time from departure time, costs of services during berth time, and the setup number of QCs. Findings demonstrated that the deep integrated model with developed QCSP algorithm and classic PSO solution demonstrates superior cost optimization compared to hybrid methods which prioritize computational efficiency at the expense of solution quality, particularly in large-scale scenarios. The trade-off between solution quality and runtime of the classic PSO, underscores the algorithm's strengths for offline optimization and significant cost savings in strategic planning but highlights challenges in dynamic, real-time applications. The effectiveness and practicality of the proposed algorithms were also validated and future research suggestions provided for more developments.
集装箱码头泊位与岸机调度同步优化
全球经济的快速增长和海上贸易的繁荣凸显了该行业在面临挑战时的韧性。海港作为国际供应链的重要枢纽,处理全球约80%的货运量,这就需要有效的规划和调度。本研究探讨泊位分配问题(BAP)、岸机分配问题(QCAP)和岸机调度问题(QCSP)的功能与深度整合规划。在此基础上,提出了一种基于深度集成方案的qc调度算法。利用粒子群优化(PSO)和动态规划(DP)方法的混合求解算法,对三种问题的MILP模型的集成方法进行了综合比较。目标函数的目标是使泊位偏离最佳泊位的成本最小化、结束时间偏离出发时间的成本最小化、泊位期间的服务成本最小化以及qc的设置数量最小化。研究结果表明,与以牺牲解决方案质量为代价优先考虑计算效率的混合方法相比,开发的QCSP算法和经典PSO解决方案的深度集成模型具有更好的成本优化,特别是在大规模场景中。经典粒子群算法在解决方案质量和运行时间之间的权衡,凸显了该算法在离线优化和战略规划中显著节省成本方面的优势,但也凸显了动态、实时应用中的挑战。验证了所提算法的有效性和实用性,并提出了进一步发展的研究建议。
