Fuzzy Regression Model and System Possibility

Abstract

This paper focuses on an interval-type fuzzy regression model that illustrates the possibility of an analyzed system by including data. In an interval-type fuzzy regression model, it is important that regression outputs illustrate how much the possibilities of an analyzed system. There are some functions to evaluate an interval-type fuzzy regression. However, this paper proposes an evaluation function that can be easily interpreted. It was confirmed that the proposed evaluation function is useful in numerical examples. Then, the results of this consideration are reported in this paper.
