2-Tuple Linguistic Aggregation Operators and Their Application in GDM Problems

In this paper, two new aggregation operators are proposed: 2-tuple choquet integral harmonic averaging (TCIHA) and 2-tuple ordered choquet integral harmonic averaging (TOCIHA), which can be used to aggregate preference information in the form of linguistic variables. Some desirable properties of these operators are studied. Finally, illustrative example is presented to demonstrate practicality and effectiveness of the developed operators.
