Port authorities are responsible for ensuring the successful execution of port operations and managing activities in compliance with international standards. The operational success of port authorities enhances the efficiency and effectiveness of port utilization. The primary objective of this study is to develop a decision support system for assessing the operational performance of port authorities. In this paper, the continuous Pythagorean fuzzy (CPF)-modified preference selection index (MPSI)-ranking technique by geometric mean of similarity ratio to optimal solution (RATGOS) hybrid method is proposed as the decision support system. This hybrid method employs CPF sets to determine expert weights based on both expertise levels and risk-taking tendencies. The weighting of operational performance criteria follows a dual approach, integrating subjective and objective methods. Subjective criteria weighting is conducted using CPF sets and expert evaluations, while objective criteria weighting is determined through the MPSI method. The operational performance levels and rankings of port authorities are then assessed using the RATGOS method. The CPF-MPSI-RATGOS hybrid method is applied in a case study of local port authorities (LPAs) managing container ports in Türkiye, using operational performance data and expert evaluations gathered through face-to-face interviews with qualified professionals possessing the necessary expertise to assess port authority performance. The findings indicate that “Ordino document submission time” is the most critical criterion in determining the operational performance levels of LPAs. Istanbul LPA is identified as the highest-performing authority in terms of operational efficiency. Based on the research outcomes, implications for LPAs and the maritime industry are proposed.
