The extended COWG operators and their application to multiple attributive group decision making problems with interval numbers

The aim of this paper is to develop two extended continuous ordered weighted geometric (COWG) operators, such as the weighted geometric averaging COWG (WG-COWG) and ordered weighted geometric averaging COWG (OWG-COWG) operators. We study some desirable properties of the WG-COWG and OWG-COWG operators, and present their application to multiple attributive group decision making (MAGDM) problems with interval numbers. Finally, an illustrative numerical example is used to verify the developed approaches.
