Abstract

There has been a complicated relationship associated with fuzzy logic and probability theory. All thetechniques in fuzzy logic discuss possibility theory and probability theory which measure two kinds ofuncertainty. In classical probability theory, a probability measure is a number between 0 and 1. Fuzzy rulebased system consists of a set of fuzzy rules with partially overlapping conditions. This paper demonstrates newmethodologies for predicting an output, when a particular input triggers with multiple fuzzy rules. This paperanalyzes the behavior of width of an interval to represent imprecision of the probability estimates. We alsopropose new applications of possibility theory and probability theory as can be applied to Fuzzy logic.
