Özet

This study proposes a three-way decision model in interval-valued Fermatean fuzzy environments and develops a novel ranking method for interval-valued Fermatean fuzzy numbers. The fundamental properties of the newly proposed ranking method are examined. Conditional probability thresholds are derived to construct the relevant interval-valued Fermatean fuzzy three-way decision rules. Furthermore, a practical three-way decision algorithm is presented for solving multi-attribute decision-making problems in interval-valued Fermatean fuzzy environments.
