Fuzzy relation equations and subsystems of fuzzy transition systems

Knowledge-Based Systems, 2013
In this paper we study subsystems, reverse subsystems and double subsystems of a fuzzy transition system. We characterize them in terms of fuzzy relation inequalities and equations, as eigen fuzzy sets of the fuzzy quasi-order Q"@d and the fuzzy equivalence E"@d generated by fuzzy transition relations, and as linear combinations of aftersets and ...

Properties of max-\(*\) fuzzy relation equations

Soft Comput., 2010
The authors establish several results about fuzzy relation equations with a max-\(*\) composition, \(``*"\) being an operator which extends min and prod in similar equations studied by \textit{C. Zhang, C. Lu} and \textit{D. Li} [J. Fuzzy Math. 14, No.~1, 53--63 (2006; Zbl 1105.03055)].

Intuitionistic fuzzy relation equations

2010 International Conference on Educational and Information Technology, 2010
In this paper, we extend the fuzzy relation equations to intuitionistic fuzzy relation equations. The definition of intuitionistic fuzzy relation equations is proposed on the basis of theory of fuzzy relation equation. Intuitionistic fuzzy relation equation is an L-fuzzy relation equation. The method with special significance is obtained as the lattice

Fuzzy Relational Equations and Universal Approximation

2016
This chapter presents the concepts of fuzzy relationships and fuzzy relational equations. These are applied to medical diagnosis and Bayesian inference. The notion of universal approximator with applications to dynamical systems, complete the chapter.

Fuzzy relational equations in monoidal logics

2004 IEEE International Conference on Fuzzy Systems (IEEE Cat. No.04CH37542), 2005
We present a general framework for solving fuzzy relational equations in monoidal logics. This framework yields the general solution equations for relational systems based on large family of many-valued logics. The proofs use as a tool certain relational inequalities that we call BK-residuated bootstrap.

Fuzzy Relation Equations in Semilinear Spaces

2010
We introduce a notion of an idempotent semilinear space and consider two systems of linear-like equations. These systems are equivalent to systems of fuzzy relation equations with sup-*and \(\inf\)-→ compositions. We show that the theory of Galois connections can be successfully used in characterizing whether these systems are solvable and, if so ...

PROCESS CONTROL USING FUZZY LOGIC AND FUZZY RELATIONAL EQUATIONS

IFAC Proceedings Volumes, 1989
Abstract First we recall the logic basis for a fuzzy controller, i.e. implication rules between observed states and control signals, and conditional inference rules. Then logic operators which take place in approximate reasoning are investigated. Grounded upon Holmblad's data cement kiln, we search for operators which yield a satisfactory result ...
