New methods for evaluating students` answer scripts using vague values

Abstract

In this paper, we present two new methods for evaluating students` answerscripts using vague values, where the evaluating marks awarded to the questions in the students` answerscripts are represented by vague values. The vague mark awarded to each question of a student`s answerscript can be regarded as a vague set, where each element in the universe of discourse belonging to the vague set is represented by a vague value. The proposed methods can evaluate students` answerscripts in a more flexible and more intelligent manner.
