Computerized fuzzy ratings: The concept of a fuzzy class

In this paper, we outline the concept of a fuzzy class used in programs for eliciting computerized fuzzy ratings. Fuzzy ratings allow respondents to provide symmetrical or asymmetrical latitudes of acceptance around a preferred point. These ratings have been used in research testing career theories and person-environment fit models. The variables defining the fuzzy class and the various functions that can be performed by it are described in the paper. The idea of a fuzzy class may be of interest to those involved in expert systems, knowledge engineering, or in fuzzy classification and measurement in general. A program, FUZRATE, written in object-oriented C++ code that uses the concept of a fuzzy class, is available on request. Both source code and a binary (executable) file are available.
