Convergence of powers of a fuzzy transitive matrix

Fuzzy Sets and Systems, 1983
Convergence of powers of a fuzzy transitive matrix is considered and some conditions for convergence are given under the max-min operation on fuzzy matrices. A fuzzy transitive matrix is a matrix which represents a fuzzy transitive relation, and has many interesting properties.

Fuzzy risk matrix

Journal of Hazardous Materials, 2008
A risk matrix is a mechanism to characterize and rank process risks that are typically identified through one or more multifunctional reviews (e.g., process hazard analysis, audits, or incident investigation). This paper describes a procedure for developing a fuzzy risk matrix that may be used for emerging fuzzy logic applications in different safety ...

Inverse of a fuzzy matrix of fuzzy numbers

International Journal of Computer Mathematics, 2009
The aim of this paper is to extend the concept of inverse of a matrix with fuzzy numbers as its elements, which may be used to model uncertain and imprecise aspects of real-world problems. We pursue two main ideas based on employing real scenarios and arithmetic operators. In each case, exact and inexact strategies are provided.

Fuzzy rank of a fuzzy matrix

Fuzzy Sets and Systems, 1991
The paper deals with matrices over the set of fuzzy numbers (fuzzy matrices). It introduces the notion of fuzzy rank of a fuzzy matrix as an integer fuzzy number. Another definition of the rank for fuzzy matrices was proposed by \textit{S. Kaguei} and \textit{A. Ohsato} [ibid. 38, No.3, 355- 364 (1990; Zbl 0726.15002)].

Fuzzy linear matrix equation

Fuzzy Optimization and Decision Making, 2009
The authors analyze fuzzy linear matrix equations of the form \(AXB=C\) for finding its fuzzy solutions, using the parametric form of the fuzzy linear system. The authors also derive necessary and sufficient conditions for the existence of the set of fuzzy solutions.

The period of powers of a fuzzy matrix

Fuzzy Sets and Systems, 2000
An \(n{\times}n\) matrix \(A = (a_{ij})\) whose components are in the unit interval \([0,1]\) is called a fuzzy matrix. A fuzzy matrix plays an important role in system models based on a fuzzy relation, and the performance of such a system depends on forming powers of a fuzzy matrix.

Matrix, Fuzzy Relation and Fuzzy Matrix

2018
A matrix is a common mathematical tool, a way to record and manage a large volume of data. It can store information succinctly. By matrix operations, you can easily process into information.

A method to find fuzzy eigenvalues and fuzzy eigenvectors of fuzzy matrix

Neural Computing and Applications, 2012
In this paper, the fuzzy eigenvalues and fuzzy eigenvectors of a fuzzy matrix have been found. To do this, the spreads are allocated to the obtained core from the corresponding crisp matrix which it makes a fuzzy number surely.

Fuzzy clustering with a fuzzy covariance matrix

1978 IEEE Conference on Decision and Control including the 17th Symposium on Adaptive Processes, 1978
A class of fuzzy ISODATA clustering algorithms has been developed previously which includes fuzzy means. This class of algorithms is generalized to include fuzzy covariances. The resulting algorithm closely resembles maximum likelihood estimation of mixture densities. It is argued that use of fuzzy covariances is a natural approach to fuzzy clustering.
