Multipurpose Aggregation in Risk Assessment

Mathematics, 2022
Risk-mitigation decisions in risk-management systems are usually based on complex risk indicators. Therefore, aggregation is an important step during risk assessment. Aggregation is important when determining the risk of components or the overall risk of

AHP-Like Matrices and Structures—Absolute and Relative Preferences

Mathematics, 2020
Aggregation functions are extensively used in decision making processes to combine available information. Arithmetic mean and weighted mean are some of the most used ones. In order to use a weighted mean, we need to define its weights.

Some properties of implications via aggregation functions and overlap functions [PDF]

International Journal of Computational Intelligence Systems, 2014
In this work, using the identification between implication operators and aggregation functions, we study the implication operators that are recovered from overlap functions.

Another look at inheritance of uniform continuity of 1-dimensional aggregation functions by their super-additive transformations [PDF]

Journal of Mahani Mathematical Research, 2022
In an earlier paper by Seliga, Siran and the second author (J. Mahani Math. Res. Center 8 (2019) 37–51) on lifting continuity properties of aggregation functions to their super- and sub-additive transformations it was shown that uniform continuity is ...

Andness Directedness for t-Norms and t-Conorms

Mathematics, 2022
Tools for decision making need to be simple to use. In previous papers, we advocated that decision engineering needs to provide these tools, as well as a list of necessary properties that aggregation functions need to satisfy.

CENTER BASED CLUSTERING AND AVERAGING AGGREGATION FUNCTIONS [PDF]

Vestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2017
We propose a new clustering method for partitioning of finite sets from Rn, which is based on the application of averaging aggregating functions and an iterative re-weighing method for searching cluster centers.

Equilibrium analysis for linear and nonlinear aggregation in network models: applied to mental model aggregation in multilevel organisational learning

Journal of Information and Telecommunication, 2022
In this paper, equilibrium analysis for network models is addressed and applied in particular to a network model of multilevel organisational learning.

A Three–Level Aggregation Model for Evaluating Software Usability by Fuzzy Logic

International Journal of Applied Mathematics and Computer Science, 2019
Rapid deployment of IT brings about new issues with software usability measurement. Usability is based on users’ experience and is strongly subjective, having a qualitative character. The users’ comfort is usually collected by surveys in their daily work.

Sub-Additive Aggregation Functions and Their Applications in Construction of Coherent Upper Previsions

Mathematics, 2020
In this paper, we explore the use of aggregation functions in the construction of coherent upper previsions. Sub-additivity is one of the defining properties of a coherent upper prevision defined on a linear space of random variables and thus we ...
