Fuzzy Sets and Their Extensions

  • Urszula BentkowskaEmail author
Part of the Studies in Fuzziness and Soft Computing book series (STUDFUZZ, volume 378)


In this chapter basic notions regarding fuzzy calculus, its history and basic properties are recalled. Moreover, extensions of fuzzy sets are briefly described and the most important results concerning interval-valued fuzzy calculus are provided. Especially, the notions of diverse order and comparability relations for interval-valued settings are discussed.
