Abstract
The Fuzzy-set Concurrent Rating method (FCR method) was developed to measure subjects' attitudes more naturally than traditional rating methods (Oda, 1995). The present paper proposes a new improved definition of the method so that it can include both recent and future research. With the new definition, the improved FCR method, which is composed of a convenient set of procedures is proposed. For the purpose of assisting the users to understand it, the algorithm of integration using Mamdani's "min-max-gravity method" is explained in detail. The integration formulae are presented as well. The formulae can fit data from 2- to 5-item arrangements by employing Mamdani's "min-max-gravity" method and Mizumoto's "algebraic product-sum-gravity" method. Besides, a variety of procedures for the application of the FCR method to psychological measurements are proposed. After the proposal of the procedures, the guidelines to apply them to practical problems are shown in table form.
