Abstract:

In the real multi-attribute group decision making problems, there exists interactions phenomena among the decision making attributes and preference of experts. A linguistic Choquet integral operator is investigated for multiple attribute group decision making. Some operational laws on linguistic evaluation scale are  introduced. Based on these operational laws and fuzzy measures, a linguistic Choquet integral operator is presented. And then its some properties are analyzed. It is pointed that the linguistic Choquet integral operator is the generalization of the linguistic OWA operator. Finally, the linguistic Choquet integral operator is applied to dealing with linguistic multi-attribute decision making problems. The process of calculation of the developed approaches and its feasibility and practicality are demonstrated by an illustrative example.
