Abstract:Maritime transportation plays a critical role in global trade as it accounts for over 80% of all merchandise movement. Given the growing volume of maritime freight, it is vital to have an efficient system for handling ships and cargos at ports. The current first-come-first-serve method is insufficient in maintaining operational efficiency, especially under complicated conditions such as parallel scheduling with different cargo setups. In addition, in the face of rising demand, data-driven strategies are necess… Show more
“…From the presented simulation results it becomes evident that the proposed model can help in achieving efficient berth and quay crane allocation. The authors of [117] propose a greedy insert-based offline model to optimize BAP when vessel information is available. They further propose an online strategy based on a reinforcement-learning algorithm to solve the problem when vessel information is uncertain.…”

Marine container terminals (MCTs) play a crucial role in intelligent maritime transportation (IMT) systems. Since the number of containers handled by MCTs has been increasing over the years, there is a need for developing effective and efficient approaches to enhance the productivity of IMT systems. The berth allocation problem (BAP) and the quay crane allocation problem (QCAP) are two well‐known optimization problems in seaside operations of MCTs. The primary aim is to minimize the vessel service cost and maximize the performance of MCTs by optimally allocating berths and quay cranes to arriving vessels subject to practical constraints. This study presents an in‐depth review of computational intelligence (CI) approaches developed to enhance the performance of MCTs. First, an introduction to MCTs and their key operations is presented, primarily focusing on seaside operations. A detailed overview of recent CI methods and solutions developed for the BAP is presented, considering various berthing layouts. Subsequently, a review of solutions related to the QCAP is presented. The datasets used in the current literature are also discussed, enabling future researchers to identify appropriate datasets to use in their work. Eventually, a detailed discussion is presented to highlight key opportunities along with foreseeable future challenges in the area.

Efficient coordinated scheduling has long been a focal point in port research, complicated by the diverse optimization goals dictated by different port characteristics. This study focuses on Yangtze River ports, exploring coordinated scheduling amidst river–sea intermodal transportation. Our research aims to reduce berth deviation costs and shorten the total scheduling time for ships, while maximizing berth utilization rates for ports. Initially, we analyzed the operational realities of Yangtze River ports and waterways. Subsequently, we innovatively introduced three key factors influencing scheduling: berth preferences, seagoing ship inspections, and planning cycles. Finally we proposed the optimized Non-dominated Sorting Genetic Algorithm III (NSGA-III). Evaluating the model using a seven-day dataset of vessel activities at Yangtze River ports revealed significant improvements: the optimized NSGA-III enhanced objective values by 30.81%, 13.73%, and 12.11% compared to the original scheduling approach, surpassing both conventional NSGA-III and NSGA-II algorithms. This study underscores the model’s efficacy in not only reducing operational costs through optimized ship and berth sequencing but also in enhancing clearance efficiency for relevant authorities.
Maritime transportation is the main transportation mode for the delivery of cargoes between different continents across the world. Container ships carrying valuable goods are served at marine container terminals (MCTs). Berth allocation and scheduling is one of the primary decision problems that have to be addressed by MCT operators when planning seaside operations. The berth allocation and scheduling problem (BASP) has high computational complexity and cannot be solved using exact optimization algorithms in acceptable computational time for large-scale problem instances. Therefore, many types of heuristic and metaheuristics have been proposed in the BASP literature. However, hyperheuristics still have not been explored for the BASP decision problem, despite their promising performance in other settings. Hence, this study proposes a comprehensive framework for hyperheuristic algorithms for berth allocation and scheduling at MCTs that could be further used to guide the future research in this area.
