Abstract

This paper presents a new method for evaluating students´ answerscripts based on interval-valued intuitionistic fuzzy sets. The fuzzy marks awarded to the answers of students´ answerscripts are represented by interval-valued intuitionistic fuzzy sets. An index of optimism λ determined by an evaluator is used, where λ ∈ [0, 1]. An index of uncertainty β is calculated denoting the degree of uncertainty of an interval-valued intuitionistic fuzzy mark, where β ∈ [0, 1]. The proposed method can overcome the drawbacks of the existing methods for students´ answerscripts evaluation. The proposed methods can evaluate students´ answerscripts in a more flexible and more intelligent manner.
