Abstract
The Fuzzy-Set Concurrent Rating Method (FCR method) was developed to measure a subjects' attitude more naturally when compared to the traditional rating method. This paper uses set function representations to present the fundamental idea required to obtain integrated values and expression degrees of one's opinion. The obtained results are noted as FCR scores. The set functions consist of "positive", "negative", "both positive and negative", and "unknown" values. The integrated values of the FCR-method are the Shapley values of the set function. In addition, we present the method to analyze a pair confrontational FCR questions and show the main effect and the sub effect of the questions on the subject.
