چکیده
In this paper we discuss an extension of fuzzy numbers, called fuzzy numbers with indeterminateness, and show how they can be used to model decision process involving incomplete information. In particular, the paper focuses on the “Don’t Know” answer to questionnaires and develops an aggregation model that accounts for these type of answers. The main contribution lies in the formalization of the interrelationships between the risk of a decision and the incompleteness of the information on which it is made.
