“…As per the United Nations Conference on Trade and Development (UNCTAD) [1,47], more than 80% of the international trade volume is handled through maritime transportation. [23,48] Studies have emphasized the significance of ports in the economic growth of a country. Given ports' vital contributions to economic development and global trade, along with the increasing interest of academicians, researchers, and policymakers, the literature on port performance has grown exponentially, especially in the last decade.…”

The maritime sector has evolved as a crucial link in countries' economic development. Given that most of the trade across regions takes place through naval transportation, the performance of the seaports has been one of the focus areas of research. As the publication volume has significantly grown in the recent past, this study critically examines the publications related to the performance of ports for exploring the evolution, identifying the trends of articles, and analyzing the citations covering the publications based on relevant keywords in Scopus database for the period 1975–April 2024. Bibliometric and scientometric analysis was done using R, Python, and VOS software tools. Results indicate the core subject areas as “port efficiency”, “data envelopment analysis” (DEA), “port competitiveness”, “simulation”, “port governance”, and “sustainability,” with "sustainability" as the most discussed and highly relevant theme that has evolved in the last five years. Bibliometric data analysis on the subject area, yearly trends, top journals of publications, citation and author analysis, impact analysis, country-wise publication, and thematic analysis with clusters are also performed to outline future research directions. The analysis indicates an exponential rise in publications in recent times and with sustainability-related studies gaining more importance, especially for empirical research on port performance and demands for future empirical research on sustainability and smart port performance subject area. The study's findings are helpful for researchers, academicians, policymakers, and industry practitioners working towards a sustainable maritime port industry.

Since the end of 2019, the outbreak of COVID-19 has severely affected port production and operation. There is little research on the systematic impact assessment. This study took Shanghai Port as an example and evaluated the impact under different scenarios through establishing a System Dynamics model. It is found that the epidemic mainly has a greater impact on passenger transport, but less on cargo transport. The ports with the function of transportation in highway, railway, and waterway were the key nodes in the international logistics network. More attention should be paid to the impact assessment of COVID-19 on ports’ production and operation. It is necessary to strengthen the port’s collection and distribution capabilities, improve port production efficiency, and further strengthen port modernization. This research method proposed in this paper can provide a reference for the impact assessment of similar events, and the empirical results can provide a reference for handling the epidemic shock for the port and shipping departments.

With the continuous prosperity of maritime transportation on a global scale and the resulting escalation in port trade volume, tugboats assume a pivotal role as essential auxiliary tools influencing the ingress and egress of vessels into and out of ports. As a result, the optimization of port tug scheduling becomes of paramount importance, as it contributes to the heightened efficiency of ship movements, cost savings in port operations, and the promotion of sustainable development within the realm of maritime transportation. However, a majority of current tugboat scheduling models tend to focus solely on the maximum operational time. Alternatively, the formulated objective functions often deviate from real-world scenarios. Furthermore, prevailing scheduling methods exhibit shortcomings, including inadequate solution accuracy and incompatibility with integer programming. Consequently, this paper introduces a novel multi-objective tugboat scheduling model to align more effectively with practical considerations. We propose a novel optimization algorithm, the Improved Grey Wolf Optimization (IGWO), for solving the tugboat scheduling model. The algorithm enhances convergence performance by optimizing convergence parameters and individual updates, making it particularly suited for solving integer programming problems. The experimental session designs several scale instances according to the reality of the port, carries out simulation experiments comparing several groups of intelligent algorithms, verifies the effectiveness of IGWO, and verifies it in the comprehensive port area of Huanghua Port to get the optimal scheduling scheme of this port area, and finally gives management suggestions to reduce the cost of tugboat operation through sensitivity analysis.
