Fuzzy relation equations and inequalities

Fuzzy Sets and Systems, 1984
Let L be a complete lattice. The author introduces a generalization of the concept of Brouwerian lattice in the form of a lattice with an implication induced by a monotone binary operation assigned in L. The induced implications in the complete lattice L(X\(\times Y)\) of the fuzzy relations, with membership functions defined on two sets X and Y and ...

PROCESSING OF FUZZY NUMBERS BY FUZZY RELATION EQUATIONS

Kybernetes, 1986
In this paper we deal with fuzzy numbers that modelize uncertain quantities present in many fields of applications, such as man‐machine systems. Main attention is paid to inverse operations for fuzzy numbers which allow one to solve equations or systems of equations with fuzzy numbers.

A new kind of fuzzy relation equations

2009 IEEE International Conference on Fuzzy Systems, 2009
In this paper, a new kind of fuzzy relational equations (FREs for short) A ∘R*x = b is first introduced, and then the problem of solving solution to the FREs is discussed, where A is an m × n matrix, x and b are an n and an m dimensional column vectors, respectively.

Fuzzy Relation Equations with Fuzzy Quantifiers

2017
In this paper, we follow the previous works on fuzzy relation compositions based on fuzzy quantifiers and we introduce systems of fuzzy relation equations stemming from compositions based on fuzzy quantifiers. We address the question, whether such systems under some specific conditions may become solvable, and we provide a positive answer. Based on the

Equations in classes of fuzzy relations

Fuzzy Sets and Systems, 1995
The author gives necessary and sufficient conditions for the existence of particular solutions of a fuzzy relation equation defined on finite sets. Precisely he characterizes the solutions which are reflexive, irreflexive, symmetric, antisymmetric, complete, transitive and idempotent, respectively.
