Abstract
Introduction and Objectives: Given the critical role of ports in global trade and supply chains, the development of sustainable port management models has become a priority in the maritime industry. Focusing on existing research in sustainable management, this research aims to develop an integrated model for evaluating and prioritizing factors affecting the sustainability of container ports. The primary objective of this research is to examine and weigh sustainability criteria across three dimensions—environmental, social, and economic—to assist port authorities in making comprehensive and inclusive decisions in port management. Accordingly, this model is intended to reduce the complexity of sustainability assessments and increase the accuracy of measuring the key factors influencing the sustainable performance of ports.
Methodology: This study applied the fuzzy Delphi method to screen and validate basic sustainability factors. Initially, 26 sustainability criteria were reviewed and validated based on existing literature and a survey of 14 experts. Subsequently, the fuzzy Full Consistency Method (FUCOM) was used to weigh and prioritize these criteria. In this stage, eight experts with relevant experience in port management and sustainability provided the necessary data through designed questionnaires. The fuzzy FUCOM method was chosen because of its ability to reduce the number of pairwise comparisons and to take account of the uncertainties involved. Through this process, the criteria were ranked based on their relative importance, and the final weights of the main factors and their corresponding sub-criteria were calculated.
Findings: The results of this study show that among the sustainability dimensions related to container ports, the environmental dimension is the most important with a weight of 0.541, while the economic and social dimensions are the next most important with weights of 0.304 and 0.154 respectively.
Among the environmental sub-criteria, water pollution management (with a relative weight of 0.1864) ranked highest, followed by air pollution management (relative weight of 0.1388) and the protection of ecosystems and habitats (relative weight of 0.1051). In the economic dimension, port operational efficiency (relative weight of 0.1760) was the most significant, followed by value-added productivity (relative weight of 0.1321) and port development financing (relative weight of 0.1192). It highlights the role of these factors in the economic development of ports. In the social dimension, health and safety (relative weight of 0.2228) were identified as the most critical criteria, while job creation and employment security (relative weight of 0.1577) and vocational skills training (relative weight of 0.1173) were also of high importance. Overall, the results of this study indicated that water and air pollution management factors, along with the protection of ecosystems and habitats, with final weights of 0.1008, 0.1388, and 0.1051, respectively, are the most influential factors in port sustainability. The findings suggest that focusing on these factors can significantly reduce the negative environmental impacts of port activities, increase stakeholder satisfaction, and enhance the global competitiveness of ports through improved environmental performance. Additionally, this approach can help ports achieve global sustainable development goals (SDGs) and align with international environmental regulations, ultimately leading to a more sustainable and responsible port system.
Conclusion: This study provides a structured method for assessing and prioritizing sustainability factors in container ports, which can help to identify areas for improvement and implement sustainable strategies. The proposed model serves as a practical tool for monitoring sustainability performance and aligning with international standards.
