Assessment of Environmental Performance of Ports Utilizing an Integrated LBWA- MARCOS Decision-Making Approach Based on Picture Fuzzy Sets

The management of a port is of critical economic significance because of its part in global trade. However, the expansion of port operations and the continued use of antiquated methods of labor have resulted in detrimental effects on the environment, thereby posing challenges to sustainability of ports. In order for ports to compete in the global market and to ensure customer satisfaction, the importance that port managers attach to environmental indicators comes to the fore. In this context, this study suggests a fuzzy integrated MCDM strategy that combines the picture fuzzy LBWA (PF-LBWA) and picture fuzzy MARCOS (PF-MARCOS) approaches in order to achieve this goal. The proposed model is also demonstrated through environmental performance analysis of ten major ports in Türkiye.
