Fuzzy relations and fuzzy groups

Information Sciences, 1985
The main result: Given a group \(G\) and a fuzzy set \(A\) on \(G\), \(A\) is a fuzzy group on \(G\) iff \(A\times A\) is a fuzzy group on \(G\times G\). A more general product of fuzzy groups was considered by \textit{H. Sherwood} [Fuzzy Sets Syst. 11, 79--89 (1983; Zbl 0529.20021)].

Fuzzy IRR with Fuzzy WACC and Fuzzy MARR

2012
In this paper, several uncertainties are considered for investment acceptability decision by IRR method. First, some parameters in weighted average cost of capital (WACC) equation are assumed to be fuzzy numbers, a fuzzy WACC is obtained, and defuzzified by t-norm and t-conorm fuzzy relations.

FUZZY SENSORS FOR FUZZY CONTROL

International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 1994
This paper introduces sensors employing a fuzzy numeric to symbolic interface. The fundamental design considerations for this kind of fuzzy symbolic sensor, or fuzzy sensor, are formally presented. Then, the use of these components for fuzzy control is discussed and illustrated.

Fuzzy coloring for fuzzy graphs

10th IEEE International Conference on Fuzzy Systems. (Cat. No.01CH37297), 2002
In this paper the questions of coloring of fuzzy graphs are observed. Definitions of separation degree and fuzzy chromatic set of fuzzy graphs are presented. A method for finding fuzzy chromatic set is suggested and substantiated.

Fuzziness indices for fuzzy clustering

The 12th IEEE International Conference on Fuzzy Systems, 2003. FUZZ '03., 2004
Some indices of fuzziness are introduced for providing helpful information in fuzzy clustering. These indices play an auxiliary role in fuzzy clustering and can be used for deciding the number of clusters by combining with another criterion. Numerical examples are given for demonstrating how these indices can be applied.

Fuzzy control with fuzzy inputs

IEEE Transactions on Fuzzy Systems, 2003
This paper is concerned with the use of fuzzy inputs in fuzzy logic controllers. A precise representation of fuzzy logic controllers by means of mappings is used to introduce different ways for dealing with fuzzy inputs. Two types of fuzzy inputs are presented and their potential use in fuzzy control is discussed.

Fuzzy contactibility and fuzzy variables

Fuzzy Sets and Systems, 1982
Abstract This paper gives some advanced developments of possibility measure theory. There are two problems being solved in this paper: 1. 1. What is the most essential property of the possibility measures? 2. 2. What is the measure extension theorem concering the possibility measures?

Fuzzy Coloring of Fuzzy Hypergraph

2006
Practical tasks of map coloring in case of objects groups’ allocation, not connected by any binary relation, come to the problem of coloring of graph [1]. This task is closely connected to the calculation of internal stable sets of graphs, calculation of chromatic number and a chromatic class of the graph.

Fuzzy Fractals and Fuzzy Turbulence

IEEE Transactions on Systems, Man and Cybernetics, Part B (Cybernetics), 2004
In this paper, we have defined and discussed fuzzy fractals from image generation point of view. We have also proposed a fuzzy system modeling of a two dimensional turbulence just as a chaotic occurrence of fuzzy vortices in a two dimensional dynamic fluid.
