Binary relations play an important role in both mathematics and information sciences. In this
paper, we focus our discussion on a fuzzy set which is approximated in the sense of the …

In this paper, we study the concept of fuzzy bi-hyperideals in ordered semihypergroups and
we present some examples in this respect. We give the main theorem which characterizes …

The bimatrix game theory concerns how two players make decisions when they are faced
with known exact payoffs. The aim of this paper is to develop a simple and an effective …

A New Generalization of Fuzzy Bi-ideals in Semigroups and Its Applications in Fuzzy Finite
State Machines Page 1 J. of Mult.-Valued Logic & Soft Computing, Vol. 24, pp. 599–623 ©2015 …

Several applied fields dealing with decision-making process may not be successfully
modeled by ordinary fuzzy sets. In such a situation, the interval-valued fuzzy set theory is …

In this article, we introduce a model of bi-matrix games based on crisp parametric payoffs via
utilizing the method of interval value function. Then, we get that equilibrium solutions of bi …

The concept of non‐k‐quasi‐coincidence of an interval valued ordered fuzzy point with an
interval valued fuzzy set is considered. In fact, this concept is a generalized concept of the …

In this paper, we generalize the concept of interval valued (∈,∈∨ qk~)-fuzzy left (right)
filters in ordered semigroups introducing and studying the notion of an interval valued …

In this paper, we first consider the general forms of interval valued (α, β)-fuzzy bi-ideals of an
ordered semigroup, where and, and several related properties are investigated. In particular …

Interval-valued fuzzy set theory (advanced generalization of Zadeh's fuzzy sets) is a more
generalized theory that can deal with real world problems more precisely than ordinary fuzzy …
