Abstract
For multiple attribute group decision-making problems, in which the attribute values are triangular intuitionistic fuzzy numbers and the attribute weight information is the linguistic evaluation, a multiple attribute group decision-making method is proposed. In the method, first, to transform the 2-tuple linguistic attribute weights to the real numbers. Then, to aggregate the experts’ preferences with triangular intuitionistic fuzzy number by the extended aggregation operators, the group overall evaluation values of the alternatives were obtained. The ranking could be present according to the weighted average area. Triangular intuitionistic fuzzy number and 2-tuple linguistic information are easier to deal with the fuzzy and the uncertain information of different decision makers. Finally, a numerical example was used to illustrate the proposed method. The result shows the approach is simple, effective, and easy to calculate.
