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.
