Stable two-sided matching decision making with incomplete fuzzy preference relations: A disappointment theory based approach

Applied Soft Computing, 2019
Practical two-sided matching decision making problems, such as marriage matching and person-job matching, are often characterized by a lack of knowledge and time constraints.

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)].

Consensus reaching process for large-scale group decision making with double hierarchy hesitant fuzzy linguistic preference relations

Knowledge-Based Systems, 2018
Large-scale group decision making (LSGDM) or complex group decision making (GDM) problems are very commonly encountered in actual life, especially in the era of data.

Consistency-Based Algorithms for Decision-Making With Interval Fuzzy Preference Relations

IEEE transactions on fuzzy systems, 2019
This paper reviews and analyzes several consistency concepts for interval fuzzy preference relations (IFPRs). On the basis of the comparisons, one can find that Krejčí's additive and multiplicative consistency concepts are more reasonable and flexible ...

Visualizing and rectifying different inconsistencies for fuzzy reciprocal preference relations

Fuzzy Sets Syst., 2019
Consistency is related with reasonableness. This paper proposes a graphical method to visualize and rectify different inconsistencies for fuzzy reciprocal preference relations (FPRs), and the consistency includes the ordinal and cardinal consistencies ...

The graph model for conflict resolution with incomplete fuzzy reciprocal preference relations

Fuzzy Sets Syst., 2019
Within the paradigm of the Graph Model for Conflict Resolution (GMCR), fuzzy reciprocal preference relations (FPRs) can be usually employed to handle decision makers' (DMs') certain and uncertain preferences.

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

FUZZY RELATION CALCULUS IN THE COMPRESSION AND DECOMPRESSION OF FUZZY RELATIONS

International Journal of Image and Graphics, 2002
We firstly review some fundamentals of fuzzy relation calculus and, by recalling some known results, we improve the mathematical contents of our previous papers by using the properties of a triangular norm over [0,1]. We make wide use of the theory of fuzzy relation equations for getting lossy compression and decompression of images interpreted as two-

α—Fuzzy Relation Equations and Decomposable Fuzzy Relations

1989
In this Ch., we investigate a new type of fuzzy relation equation defined on finite sets and with membership functions on a complete Brouwerian lattice. We characterize the entire set of the solutions when the fuzzy equation is assigned on a linear lattice. We also study when a fuzzy relation is pointwise decomposable in the intersection (resp.

Fuzzy relations and fuzzy functions

Fuzzy Sets and Systems, 1986
The author introduces, on a complete Brouwerian lattice L, interesting definitions of L-valued fuzzy equivalence relation, L-valued fuzzy function, L-fuzzy partition, and he goes deeply into their links. Noteworthy consequence of this new definition is that L-fuzzy-functions, so defined, assume values in a Boolean subalgebra of the lattice L. Later the
