Group decision making based on q-rung orthopair fuzzy weighted averaging aggregation operator of q-rung orthopair fuzzy numbers

Abstract

In this paper, we propose the q-rung orthopair fuzzy weighted averaging (q-ROFWA) aggregation operator (AO) of q-rung orthopair fuzzy numbers (q-ROFNs). The proposed q-ROFWA AO of q-ROFNs can overcome the drawbacks of the q-rung orthopair fuzzy interaction weighted Hamy mean (q-ROFIWHM) AO and the q-rung orthopair fuzzy power weighted Maclaurian symmetric mean (q-ROFPWMSM) AO of q-ROFNs. Moreover, we propose a new group decision making (GDM) method based on the proposed q-ROFWA AO of q-ROFNs. The proposed GDM method can overcome the drawbacks of the existing GDM methods. It provides us a very useful approach to deal with GDM problems in q-rung orthopair fuzzy environments.
