On the properties of equidifferent OWA operator [PDF]

open access: yes, 2006
Getting OWA weights under given orness level is an active topic in the OWA operator research. The paper proposes a series of weights generating methods in equidifferent forms.

The solution equivalence of minimax disparity and minimum variance problems for OWA operators [PDF]

open access: yes, 2006
The aim of this paper is to answer the open question of Wang and Parkan (Information Sciences 175 (2005), 20–29) that the solutions of maximum entropy OWA operator problem under given orness level and the minimax disparity OWA operator problem under ...

Double ore extensions

open access: yesJournal of Pure and Applied Algebra, 2008
A double Ore extension is a natural generalization of the Ore extension. We prove that a connected graded double Ore extension of an Artin-Schelter regular algebra is Artin-Schelter regular. Some other basic properties such as the determinant of the DE-data are studied.

On the properties of parametric geometric OWA operator [PDF]

open access: yes, 2003
Based on the properties of ordered weighted averaging (OWA) operator weights, the parametric geometric OWA (PGOWA) operator and parametric maximum entropy OWA (PMEOWA) operator are proposed. The properties of PGOWA operator are analyzed.

Unstable Interaction in Multiple Criteria Decision Problems

open access: yes, 2014
International audienceIn this paper, we present a decision-aid method with interacting criteria. The fuzzy measures used to aggregate the criteriadepend on the considered alternatives. Pairwise comparisons on the importance of criteria and some levels of

Double Ore Extensions Versus Iterated Ore Extensions [PDF]

open access: yesCommunications in Algebra, 2011
Motivated by the construction of new examples of Artin-Schelter regular algebras of global dimension four, J.J. Zhang and J. Zhang (2008) introduced an algebra extension $A_P[y_1,y_2;σ,δ,τ]$ of $A$, which they called a double Ore extension. This construction seems to be similar to that of a two-step iterated Ore extension over $A$.

Approximation of Fuzzy measures Using Second Order measures: Estimation of Andness Bounds

open access: yes, 2013
In this paper we analyze the compensation property of a second order fuzzy measure in the context of a multi-attribute problem. In particular, we show that the disjunction/conjunction behavior (andness/orness) changes with the number of criteria to be ...

Some Notes on Monotone TSK Fuzzy Inference Systems [PDF]

open access: yes, 2023
This article presents our recent research on monotone Takagi-Sugeno-Kang (TSK) Fuzzy inference systems (FISs). We outline a few remarks on the necessary and sufficient conditions for TSK-FIS to be monotone, building upon the Ordered Weighted Averaging ...

Maximal orness weights with a fixed variability for owa operators

open access: yes, 2006
When using the ordered weighted average operator, it can happen that one wants to optimize the variability (measured by the entropy (maximal) or by the variance (minimal)) of the weights while keeping the orness of this operator at a fixed level.

Determining optimal road safety performance scores under weight and orness restrictions

open access: yes, 2009
In this paper, 21 European countries are compared on their road safety performance. More specifically, several safety performance indicators are combined in one road safety index.
