It is employed to handle the concept of partial truth, where the truth value may range between … See more Classical logic only permits conclusions that are either true or false. However, there are also propositions with variable answers, such as one might find when asking a group of people to identify a color. In such instances, the truth appears as the result of … See more Since the fuzzy system output is a consensus of all of the inputs and all of the rules, fuzzy logic systems can be well behaved when input values are not available or are not … See more Probability Fuzzy logic and probability address different forms of uncertainty.

WebThe uncertainty in the commu- nication graph is considered as a fuzzy number, which is a more general case of interval uncertainty considered in the previous works [7–9]. In this type of uncertainty, the possibility of the occurrence of any value within the interval is also considered in calculations. WebType-2 fuzzy sets and systems generalize standard Type-1 fuzzy sets and systems so that more uncertainty can be handled. From the beginning of fuzzy sets, criticism was made about the fact that the membership function of a type-1 fuzzy set has no uncertainty associated with it, something that seems to contradict the word fuzzy, since that word …
