Managing hesitant heterogeneous information in decision making

Decision making is a usual process for human beings in their daily life. The complexity of real world decision making problems imply the necessity of multiple points of view. Since experts may provide their assessments by using different domains according to their knowledge area and background. Different approaches have been introduced in the literature, nevertheless, none of them has considered the use of hesitant information. In this contribution, we propose an approach that manages hesitant heterogeneous information such as hesitant fuzzy sets and hesitant fuzzy linguistic term sets with other information as numerical, linguistic and interval-valued. A hesitant heterogeneous decision making model is also presented.
