Abstract:  Based on the uncertainty of binary connection number in the set pair analysis, connection variables are extended to interval 2-tuple linguistic environment, and the 2-tuple linguistic connection variables are defined. Moreover, some operational laws of 2-tuple linguistic connection variables are proposed and several new arithmetic aggregation operators are developed. For the multiple attributes decision making problem in which the attribute values are in the form of interval 2-tuple linguistic variables and the weights of attributes are unknown, an approach to applying the 2TLCGPOWA operator to uncertain multiple attribute group decision making is developed. Finally, a numerical example of tenure and promotion evaluation of teachers of a university is given to illustrate the feasibility and effectiveness of the new approach.
