This paper conducts a comprehensive bibliometric analysis of the Container Relocation Problem (CRP) by using 342 relevant papers retrieved from the Scopus database (2006–2025) via precise keyword strategies. This paper systematically organizes fragmented research findings, categorizes approaches by problem type, objectives, solution methods, and maps the evolution of CRP research. Additionally, this paper examines publication trends, geographical and institutional contributions, author collaborations, high-impact journals, and patterns of keyword co-occurrence. This paper consolidates knowledge, standardizes terminology, evaluates methods, bridges theory and practice, and charts future research, ultimately advancing both academic rigor and industrial efficiency in container logistics.

Greenhouse gas emissions in the shipping industry have been a major challenge in the sustainability of international transportation. This paper studied shore power management for river shipping, which has become increasingly popular in some international transport networks. We discussed stakeholders’ incentives and concerns regarding shore power and found that vessel owners play one of the dominant roles in the wide implementation of shore power. Then, a mathematical model is developed to show the advantages of shore power by combining it with an analysis of the optimal oil inventory plan for vessels. When the plan of the oil inventory on vessels is well designed, using shore power could be more beneficial than oil even if the shore power has a higher price than the latter because using shore power can provide the vessel with more options to improve the oil inventory plan by reducing oil consumption during berthing and the number of refueling. Sensitivity analyses are conducted to obtain a better understanding of the impact of the parameters on the performance of shore power. Our policy suggestions and findings can shed lights on how to make incentive policies for a wider and easier implementation of shore power under international shipping.
