Aggregation Operators of Interval-Valued 2-Tuple Linguistic Information

The group decision-making problem with linguistic information evaluation values of decision makers are used based on 2-tuple interval-valued. Operational laws on interval value 2-tuple are introduced. On the basis of these laws, new aggregation operators are introduced by using the Choquet integral. A multiple attribute decision-making method based on these aggregation operators is proposed. An example is given to illustrate the efficiency, practicality, and feasibility of our method.
