A Study on Signed Fuzzy Sets and Relations

Abstract

Introduction: Signed fuzzy sets are defined and illustrated in this article. Definitions are given for the union and intersection of signed fuzzy sets, the inclusion of two signed fuzzy sets in a signed fuzzy set, and the collection of signed fuzzy sets. We also describe how a list of items and an arbitrary signed fuzzy set can intersect and union. Some of the aspects of Signed-FRs are described, along with their definition, composition of two Signed-FRs, and inverse. The notion of semiotic fuzzy relations that are reflexive, transitive, and symmetric is suggested. We talk about $\alpha$-cut, strong cut, and some of its characteristics.
