Fuzzy-Set Method For Grade Evaluation

บทคัดย่อ

Abstract

This paper is comparing 3 methods of student grading evaluation i.e. by instructor experiences, T-score and Fuzzy-set.The Instructor experiences method depends on the criteria strictly. The second Method is obtained by transforming the raw score into T-score. The third Method can be obtained by transforming the raw score into the fuzzy number by the expert opinion. The result shows that the Fuzzy Method is the compromised method between the criteria referenced and the T-score Method since it is not only the expert experience dependence as in the first method but also mathematically formulated as in the second method as well. Thus, the Fuzzy method is more reasonable.
