Interval Ranges of Fuzzy Sets Induced by Arithmetic Operations Using Gradual Numbers
Mathematics, 2021 Wu introduced the interval range of fuzzy sets. Based on this, he defined a kind of arithmetic of fuzzy sets using a gradual number and gradual sets. From the point of view of soft computing, this definition provides a new way of handling the arithmetic ...

Modeling Uncertainty with Interval Valued Fuzzy Numbers [PDF]
, 2018 This article describes how risk assessment is a significant aid in decision-making process. It is usually performed using models and a ‘model' is a function of some parameters which are usually affected by uncertainty due to lack of data, imprecision ...

Nearest interval-valued approximation of interval-valued fuzzy numbers [PDF]
, 2016 In this paper, we proposed a new interval-valued approximation of interval-valued fuzzy numbers, which is the best one with respect to a certain measure of distance between interval-valued fuzzy numbers.

SMOOTH NUMBERS IN SHORT INTERVALS [PDF]
International Journal of Number Theory, 2007 We show that for any ∊ > 0, there exists c > 0, such that for all x sufficiently large, there are x1/2 ( log x)- log 4 - o(1) integers [Formula: see text], all of whose prime factors are [Formula: see text].

Cubicity of Interval Graphs and the Claw Number [PDF]
Electronic Notes in Discrete Mathematics, 2009 AbstractLet G(V, E) be a simple, undirected graph where V is the set of vertices and E is the set of edges. A b‐dimensional cube is a Cartesian product I1×I2×···×Ib, where each Ii is a closed interval of unit length on the real line. The cubicity of G, denoted by cub(G), is the minimum positive integer b such that the vertices in G can be mapped to ...

The interval grey numbers ranking based on risk preferences [PDF]
, 2017 In this paper, a new method for ranking interval grey numbers to address the challenge in multi-criteria decision-making problems with interval grey numbers has been proposed. This new method involves the risk preferences of decision makers.

A note on the interval number of a graph
Discrete Mathematics, 1985 Three results on the interval number \(i(G)\) and d-dimensional interval number \(i_d(G)\) of a graph \(G\) with n vertices are presented. Theorem 1. The inequalities \(i(G)\geq n/4 lg_2 n\), \(i_d(G)\geq n/4d lg_2 n\) hold for almost every graph (i.e.

The Number of Intervals in the $m$-Tamari Lattices [PDF]
The Electronic Journal of Combinatorics, 2012 An $m$-ballot path of size $n$ is a path on the square grid consisting of north and east steps, starting at $(0,0)$, ending at $(mn,n)$, and never going below the line $\{x=my\}$. The set of these paths can be equipped with a lattice structure, called the $m$-Tamari lattice and denoted by $\mathcal{T}_n^{(m)}$, which generalizes the usual Tamari ...
