In this work we present a novel axiomatic framework for subsethood measures in type-2
fuzzy sets. It differs from previous approaches in two key ways. First, the degree of …

In fuzzy logic, most of the implication operators are based on generalizations of the classical,
material implication. That is, these implications are defined as the disjunction of the negated …

In this work, we consider De Luca and Termini's notion of non-probabilistic entropy, and we
extend some entropy-like measures of the degree of fuzziness to type-2 fuzzy sets. With this …

Obtaining the complement of a fuzzy set is usually done through a negation function. On the
other hand, the antuonym of a predicate, which in classical logic could be considered to be …

Entropy, as a measure of “disorder” of a set, has been studied by different authors in the
frameworks of fuzzy, intuitionistic, and interval-valued fuzzy sets. Given the growing interest …

El objetivo principal de este trabajo es definir nuevas medidas de embebimiento y similitud
para conjuntos difusos intervalo-valorados que posteriormente puedan aplicarse al …
