The Uncertain Two-tuple Ordered Weighted Averaging Operator


Yao Zhang, Zhi-Ping Fan


Vol. 6  No. 9  pp. 78-83


Many multiple attribute group decision making (MAGDM) problems with linguistic information involve uncertainties, which significantly increase the complexity and difficulty in decision analysis. In order to solve such problems, we require appropriate aggregation operators that are capable of dealing with uncertain linguistic information. In this paper, firstly, the uncertain two-tuple linguistic information is described. Then, a new uncertain linguistic aggregation operator called uncertain two-tuple ordered weighted averaging (UTOWA) operator is proposed and some desirable properties of the UTOWA operator are analyzed. Finally, it is pointed out that the proposed operator can be applied to solve MAGDM problems with uncertain linguistic information and also enrich the existing approaches to aggregating uncertain linguistic information.
