On set-function representations of the multi-attribute evaluation values: Combined set-functions among positive and negative evaluations

Abstract

On the analyses of multi-attribute evaluation values, we usually use the mean values with examinee. The mean values often hide the rank differences of criterion among the subjects. The set-function representations of the evaluation values are depended on the rank information and keep the rank differences of each subject response. We define positive, negative and combined set-function representations. The positive and negative values are differences from median values of multi-attribute evaluation values, that are vary according to examinee.
