FUZZY CLUSTERING BASED ON INTUITIONISTIC FUZZY RELATIONS

International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2004
It is well known that an intuitionistic fuzzy relation is a generalization of a fuzzy relation. In fact there are situations where intuitionistic fuzzy relations are more appropriate. This paper discusses the fuzzy clustering based on intuitionistic fuzzy relations. On the basis of max -t & min -s compositions, we discuss an n-step procedure which

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.

Confluence and related properties of fuzzy relations

2009 IEEE International Conference on Fuzzy Systems, 2009
Confluence and termination are essential properties of relations connected to the idea of rewriting and substituting which appear in abstract rewriting systems. This paper presents a preliminary study of confluence, termination, and related properties from the point of view of fuzzy logic leaving the ordinary notions a particular case when the ...

Collective relations of fuzzy relational structures

Journal of Intelligent & Fuzzy Systems, 2018
This paper focuses on fuzzy relational structures. In order to collect the knowledge that has been acquired with regard to fuzzy relational structures, the concept of collective relations is proposed and characterizations of collective relations are investigated. A method on computing the largest collective relation is further given. Moreover, based on

Fuzzy Limits and Fuzzy Nearness Relation

2001
The aim of this paper is to introduce the notion of fuzzy limit within the fuzzy analysis developed in the concept of fuzzy nearness relation. The main results concern the corresponding calculus.

Fuzzy Closeness Relation as a Basis for Weakening Fuzzy Relational Queries

2004
Query weakening is the modification of the conditions involved in a query in order to obtain a less restrictive variant and then a non empty set of answers. The aim of the paper is to propose an approach for dealing with this problem in the case of fuzzy queries against relational databases.
