Uncertain Linguistic Power Geometric Operators and Their Use in Multiattribute Group Decision Making

الملخص EN

Based on the extended triangular norm, several new operational laws for linguistic variables and uncertain linguistic variables (ULVs) are defined.

To avoid the limitations of existing linguistic aggregation operators, a series of extended uncertain linguistic (UL) geometric aggregation operators are proposed on the basis of the extended triangular norm.

In addition, a multiattribute group decision making (MAGDM) method dealing with UL information is developed based on the extended UL geometric aggregation operators.

Finally, an example is presented to show the efficiency of the developed approach in solving MAGDM problems.
