Hospital site selection based on two-phase multi-criteria group decision-making method using interval-valued Fermatean fuzzy Aczel–Alsina averaging aggregation operators

Future Business Journal
The interval-valued Fermatean fuzzy set theory plays an essential role in modeling the problem, which involves inadequate and imprecise information in a real-life scenario.

A multiple attribute group decision making model based on 2-tuple linguistic pythagorean fuzzy dombi aggregation operators for optimal selection of potential global suppliers

Heliyon
Multiple-Attribute Group Decision-Making (MAGDM) is a significant area of research in decision-making, and its principles and methodologies are widely implemented. A Pythagorean Fuzzy Set (PFS) is an extension of an Intuitionistic Fuzzy Set (IFS) that is

C × K-Nearest Neighbor Classification with Ordered Weighted Averaging Distance

, 2016
In this study, OWA (Ordered Weighted Averaging) distance based C x K-nearest neighbor algorithm (C x K-NN) is considered. In this approach, from each class, where the number of classes is C, K-nearest neighbors are taken.

A goal-based weighting for composite indicators constructed through Ordered Weighted Averaging (OWA) operator

MethodsX
The Ordered Weighted Averaging (OWA) operator is a multicriteria method that has conquered space among researchers in the composite indicators field. Typically, OWA operator weights are defined by the decision maker.

The Gini index,the dual decomposition of aggregation functions, and the consistent measurement of inequality [PDF]

In several economic fields, such as those related to health, education or poverty, the individuals’ characteristics are measured by bounded variables. Accordingly, these characteristics may be indistinctly represented by achievements or shortfalls.

The generalized hybrid averaging operator and its application in decision making [PDF]

, 2010
We present the generalized hybrid averaging (GHA) operator. It is a new aggregation operator that generalizes the hybrid averaging (HA) operator by using the generalized mean. Thus, we are able to generalize a wide range of mean operators such as the HA,

Modelling fraud detection by attack trees and Choquet integral [PDF]

Modelling an attack tree is basically a matter of associating a logical ÒndÓand a logical ÒrÓ but in most of real world applications related to fraud management the Ònd/orÓlogic is not adequate to effectively represent the relationship between a parent ...
