Density aggregation operators based on the intuitionistic trapezoidal fuzzy numbers for multiple attribute decision making

open access: yesTechnological and Economic Development of Economy, 2014
With respect to the multiple attribute decision making problems in which the attribute values take the form of the intuitionistic trapezoidal fuzzy numbers, some methods based on density aggregation operators are proposed.

The number of primes in a short interval. [PDF]

open access: yesHardy-Ramanujan Journal, 1993
We prove in this paper that for $y=x^{\theta}, \frac{11}{20}<\theta\leq\frac{7}{12}$ and $x$ large enough, we have $0.99\frac{y}{\log x}\leq\pi(x)-\pi(x-y)\leq1.01\frac{y}{\log x}$.

Probabilistic aggregation operators and their application in uncertain multi-person decision-making / Tikimybiniai sumavimo operatoriai ir jų taikymas priimant grupinius sprendimus neapibrėžtoje aplinkoje

open access: yesTechnological and Economic Development of Economy, 2011
We present the uncertain probabilistic ordered weighted averaging (UPOWA) operator. It is an aggregation operator that uses probabilities and OWA operators in the same formulation considering the degree of importance of each concept in the analysis ...

Ranking of Interval Valued Neutrosophic Numbers by Qualitative and Quantitative Criteria [PDF]

open access: yesNeutrosophic Sets and Systems, 2022
In Operations Research, making decisions based on multiple criteria is crucial. Neutrosophic numbers produce a more efficient conclusion when dealing with Fuzzy Multi Criteria Decision Making (MCDM) problems.

Uncertain group decision-making with induced aggregation operators and Euclidean distance

open access: yesTechnological and Economic Development of Economy, 2013
In this paper, we present the induced uncertain Euclidean ordered weighted averaging distance (IUEOWAD) operator. It is an extension of the OWA operator that uses the main characteristics of the induced OWA (IOWA), the Euclidean distance and uncertain ...

A new interval-valued approximation of interval-valued fuzzy numbers [PDF]

open access: yes, 2015
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.

Application of the interval approach to determine the exploitation time of pipelines [PDF]

open access: yesArchives of Civil Engineering
The fundamental problem from the point of view of pipeline exploitation in KGHM Polska Miedz S.A. is the very high overwearing of the pipes used for the transport of tailings, as well as determining the time of trouble-free operation of pipe system ...

Approximation numbers of Sobolev embedding operators on an interval [PDF]

open access: yes, 2004
Consider the Sobolev embedding operator from the space of functions in W-1,W-p(I) with average zero into L-p, where I is a finite interval and p > 1. This operator plays an important role in recent work. The operator norm and its approximation numbers in

The interval number of a planar graph: Three intervals suffice

open access: yesJournal of Combinatorial Theory, Series B, 1983
AbstractSuppose each vertex of a graph G is assigned a subset of the real line consisting of at most t closed intervals. This assignment is called a t-interval representation of G when vertex v is adjacent to vertex w if and only if some interval for v intersects some interval for w.
