Similarity measure for type-2 fuzzy sets with an application to students' evaluation
In this paper, we propose a new similarity measure for type-2 fuzzy sets. Validation has been investigated through the consistency of the proposed similarity measure. For practical use, a new method is proposed for the students answer book evaluation using the proposed similarity measure. This method is illustrated by the numerical example.  2015 Wiley Periodicals, Inc. Comput. Appl. Eng. Educ.
