Bustince Sola, HumbertoBurillo López, Pedro2017-02-102017-02-1019951310-4926https://academica-e.unavarra.es/handle/2454/23504In this paper we present a theorem that allows us to construct interval-valued intuitionistic fuzzy sets from intuitionistic fuzzy sets. We also study the way of recovering intuitionistic fuzzy sets used in the construction of the interval-valued intuitionistic fuzzy set from different operators. We analise the numerical measures of information of the internal-valued intuitionistic fuzzy set constructed in function with the numerical measures of information of the intuitionistic fuzzy sets used in its construction. We review the most important properties of intuitionistic fuzzy sets and of internal-valued intuitionistic fuzzy sets and we analise three operators among these sets along with their properties.12 p.application/pdfengFuzzy setIntuitionistic fuzzy setInterval-valued intuitionistic fuzzy setIntuitionistic entropyInterval-valued intuitionistic entropyOperators on interval-valued intuitionistic fuzzy setsArtículo / ArtikuluaAcceso abierto / Sarbide irekiainfo:eu-repo/semantics/openAccess
