2-Tuple Linguistic Power Aggregation Operators and Their Application to Multiple Attribute Group Decision Making

Aims: The aim of this paper is to develop several 2-tuple linguistic power aggregation operators for aggregating 2-tuple linguistic information.
Study Design: We first introduce several power aggregation operators and then extend these operators to 2-tuple linguistic environments.
Place and Duration of Study: We investigate several useful properties of the developed operators and discuss the relationships between them.
Methodology: Furthermore, the new aggregation operators are utilized to develop two approaches to multiple attribute group decision making with 2-tuple linguistic information.

Results: We develop several 2-tuple linguistic power aggregation operators to aggregate input arguments taking the form of 2-tuples.
Conclusion: Finally, two practical examples are provided to illustrate the effectiveness and practicality of the proposed approaches.
