Hajlaoui Sonia, Halouani Nesrin, Habib Chabouchoub
Decision making problems with fuzzy linguistic information and Choquet integral is investigated in this paper, to introduce three new aggregation operators: 2-tuple choquet integral averaging operator (TCIA), 2-tuple ordered choquet integral averaging operator (TOCIA) and combined 2-tuple choquet integral averaging operator which can be used to aggregate preference information that takes not only the form of linguistic variables but also study some of its desirable properties. Also, we developed a practical method based on TCIA as well as TOCIA operators for multiple attribute group decision making. Furthermore, in this approach alternative assessments are computed by the aggregation of 2-tuple linguistic information. Therefore, ranking alternatives or selecting the most desirable ones will be the outcome of the comparison between the 2-tuple linguistic information. Ultimately, the demonstration of the developed approaches, its practicality and its effectiveness is proved by a numerical example and a comparison with results issued from Wan method (Knowl-Based Syst 45:31–40, 2013).
