Özet
The Fermatean hesitant fuzzy set, obtained by
combining Fermatean fuzzy sets and hesitant fuzzy sets, can be used in practice
to simplify the solution of complex multi-criteria decision-making problems.
The sine trigonometric function maintains symmetry and periodicity about the
origin and thus fulfills the ambitions of decision makers in selecting the best
options. In this presentation, some basic operations using the sine
trigonometric function are presented for Fermatean hesitant fuzzy sets. We
define Fermatean hesitant fuzzy weighted average and Fermatean hesitant fuzzy
weighted geometric aggregation operators. Based on these new aggregation
operators, we propose an algorithm for multi-criteria decision-making with
Fermatean hesitant fuzzy information.
