Abstract

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.
