Hesitant T-spherical Dombi fuzzy aggregation operators and their applications in multiple criteria group decision-making

Abstract A hesitant fuzzy (HF) set is an extension of the sets and a T-spherical (T-SFS) generalization spherical (SFS). HF has significant role for modelling disagreements decision-makers over membership degree element. Also, T-SFS quite effective in uncertainty decision-making (DM) problems. In this paper, we define concept (HT-SF) (HT-SFS) by combining concepts T-SFS, present some set-theoretical operations HT-SFSs. We also develop Dombi on aggregation operators based operators, including weighted arithmetic averaging operator, geometric ordered investigate properties them. addition, give multi-criteria group method algorithm proposed under environment. To show process method, example related to selection most suitable person assistant professorship position university. Besides this, comparative analysis with existing reveal advantages authenticity our technique.
