碩士 === 國立臺灣科技大學 === 資訊工程系 === 100 === In recent years, some methods have been presented for students’ answerscripts evaluation base on fuzzy sets. In this thesis, we present a new method for evaluating students’ answerscripts based on interval-valued intuitionistic fuzzy sets, where the fuzzy marks awarded to the answers of students’answerscripts are represented by interval-valued intuitionistic fuzzy sets. In the proposed method, we use two parameters to evaluate students’ answerscripts, where the one is the index of optimism determined by an evaluator indicating the degree of the optimistic of the evaluator. The larger the value of , the more the optimistic of the evaluator; the other one is the index of uncertainty denoting the degree of uncertainty of an interval-valued intuitionistic fuzzy mark. The larger the value of , the more the uncertainty of an interval-valued intuitionistic fuzzy mark. The proposed method can overcome the drawbacks of the existing methods for students’ answerscripts evaluation. Moreover, we also present a generalized method for students’ answerscripts evaluation using interval-valued intuitionistic fuzzy sets. The proposed methods can evaluate students’ answerscripts in a more flexible and more intelligent manner.
