Multiple attribute decision-making based on different types of Dombi aggregation operators under Fermatean fuzzy information.

For multiple attribute decision-making problem under Fermatean Fuzzy data environment, few existing operators are considered to interrelate among the attributes. In this paper, utilizing Dombi t-norm and t-conorm operations on Fermatean fuzzy number, some operators are defined. The operators are Fermatean fuzzy Dombi weighted averaging operator, Fermatean fuzzy Dombi ordered weighted averaging operator, Fermatean fuzzy Dombi weighted geometric operator, and Fermatean fuzzy Dombi ordered weighted geometric operator. At last, a multiple attribute decision-making problem is considered and a model related to this problem is developed. Also a numerical example is stated to illustrate the proposed model.
