“…Vessel traffic optimization refers to organizing a large number of vessels to enter and leave the canal in an orderly manner within a given period of time so that waiting time is shorter, thus reducing vessel delays and improving the efficiency of vessel traffic. The target of the traffic organization is all the ships of different types and sizes that pass through the canal every day, some of which enter the port via the canal from the outer sea or outer anchorage [18][19][20][21].…”

The International Maritime Organization (IMO) has been progressively implementing stricter regulations on ship carbon emissions, leading to many vessels adopting the virtual arrival (VA) method to reduce their carbon footprint. However, the effectiveness of the traditional VA method often varies in busy ports with complex traffic organization scenarios. To address this, our study presents a novel, comprehensive model that integrates vessel scheduling with the VA approach. This model is designed to achieve a dual objective: reducing carbon emissions through virtual arrival while simultaneously minimizing vessel waiting times. In addition to these goals, it incorporates essential aspects of safety, efficiency, and fairness in port management, utilizing the NSGA-2 algorithm to find optimal solutions. This model has been tested and validated through a case study at Ningbo-Zhoushan port, employing its dataset. The results demonstrate that our innovative model and algorithm significantly outperform traditional scheduling methods, such as First-Come-First-Serve (FCFS) and Virtual-Arrival Last-Serve (VALS), particularly in terms of operational efficiency and reduction in vessel carbon emissions.

“…In recent years, with the continuous development of unmanned surface vehicle (USV) swarm coordination technology, the formation technology of multiple USVs has been increasingly applied in fields such as marine data collection [1], collaborative search and rescue [2,3], cooperative escorting [4], and collaborative transportation [5]. During the execution of various formation tasks by multiple USV clusters, collision avoidance among USVs, as well as avoidance of obstacles such as reefs, buoys, and ice floes on the sea surface, is a fundamental requirement [6][7][8][9][10].…”

This paper studied the collision avoidance issue in the formation-containment tracking control of multi-USVs (unmanned surface vehicles) with constrained velocity and driving force. Specifically, based on a dual-layer control framework, it designed a multi-USV formation-containment tracking control strategy that accounts for constrained motion velocity and input driving force and validated the stability of this strategy using the Lyapunov method. Then, by utilizing zeroing control barrier function certificates, it considered collision avoidance among USVs with various roles as well as between each USV and static obstacles. A collision-free multi-USV formation-containment tracking control strategy considering constrained motion velocity and driving force was thus established, and its effectiveness was validated through the proposed simulation.
