Fuzzy sets
WebFuzzy sets are a generalization of ordinary sets, and they may be combined by operations similar to set union, intersection, and complement. However, some properties of ordinary set operations are no longer valid for fuzzy sets. WebFuzzy Set Theory. Fuzzy set theory is a research approach that can deal with problems relating to ambiguous, subjective and imprecise judgments, and it can quantify the linguistic facet of available data and preferences for individual or group decision-making (Shan et al., 2015a).

Fuzzy sets
Did you know?
In mathematics, fuzzy sets (a.k.a. uncertain sets) are sets whose elements have degrees of membership. Fuzzy sets were introduced independently by Lotfi A. Zadeh in 1965 as an extension of the classical notion of set. At the same time, Salii (1965) defined a more general kind of structure called an L … See more A fuzzy set is a pair $${\displaystyle (U,m)}$$ where $${\displaystyle U}$$ is a set (often required to be non-empty) and $${\displaystyle m\colon U\rightarrow [0,1]}$$ a membership function. The reference set See more A fuzzy number is a fuzzy set that satisfies all the following conditions: • A is normalised; • A is a convex set; • $${\displaystyle \exists !x^{*}\in A,\mu _{A}(x^{*})=1}$$; See more A measure d of fuzziness for fuzzy sets of universe $${\displaystyle U}$$ should fulfill the following conditions for all $${\displaystyle x\in U}$$: 1.

This approach, which began in 1968 shortly after the introduction of fuzzy set theory, led to the development of Goguen categories in the 21st century. In … See more There are many mathematical constructions similar to or more general than fuzzy sets. Since fuzzy sets were introduced in 1965, many new mathematical constructions and theories treating imprecision, inexactness, ambiguity, and … See more WebA fuzzy set is defined in terms of a membership function which is a mapping from the universal set U to the interval [0,1]. A characteristic function is a special case of a membership function and a regular set (a.k.a a crisp set) is a special case of a fuzzy set. Thus the concept of a fuzzy set is a natural generalization of the concept of ...

WebApr 15, 2024 · The fuzzy set theory, introduced by Zadeh in 1965, has led to its success in several fields. One of the extensions of fuzzy sets is the IVIFS, which has proven to have a better ability to handle uncertainties, thereby widely used in solving decision-making problems. As an extension of this, interval-valued trapezoidal intuitionistic fuzzy set ...
