This paper proposes a new Fermatean fuzzy entropy for Fermatean fuzzy sets. Fermatean fuzzy entropy determines the quantity of information in the Fermatean fuzzy set. Thus, the proposed entropy provides a new, flexible, valuable tool in complex multi-criteria problems where uncertain data and inaccurate information are considered. In this study, an integrated multi-criteria decision-making method consisting of entropy, the "Pivot Pairwise Relative Criteria Importance Assessment", and "Measurement of Alternatives and Ranking according to Compromise Solution" methods based on a Fermatean fuzzy set is presented.
