Selection of Ice Crossing Point location using hybrid MCDM model Fuzzy AHP-EWAA-Fuzzy CoCoSo

This paper investigates the selection of locations for tank crossings over frozen water obstacles using a hybrid Fuzzy Analytic Hierarchy Process (AHP)–Einstein Weighted Arithmetic Average (EWAA)–Fuzzy Combined Compromise Solution (CoCoSo) model. The analysis includes key criteria relevant to the selection process. The Fuzzy AHP method enables precise determination of criterion weights based on expert opinions, aggregated using the EWAA operator, while Fuzzy CoCoSo provides a comprehensive analysis of alternatives to identify the optimal location. The results show that the combination of these methods offers a reliable framework for decision-making under complex conditions. Sensitivity analysis confirms the stability of the results, and comparative analysis supports the validity of the Fuzzy CoCoSo method. The model proves to be efficient and reliable for selecting locations for tank crossings over frozen water surfaces, providing a foundation for future research and practical application.
