Aggregation operators based on indistinguishability operators
International Journal of Intelligent Systems, 2006 This article gives a new approach to aggregating assuming that there is an indistinguishability operator or similarity defined on the universe of discourse. The very simple idea is that when we want to aggregate two values a and b we are looking for a value l that is as similar to a as to b or, in a more logical language, the degrees of equivalence of ...

Efficient MaxCount and threshold operators of moving objects [PDF]
, 2008 Calculating operators of continuously moving objects presents some unique challenges, especially when the operators involve aggregation or the concept of congestion, which happens when the number of moving objects in a changing or dynamic query space ...

On distributivity between aggregation operators with annihilator and Mayor’s aggregation operators
Filomat, 2018 The issue of distributivity for different classes of aggregation operators is a topic that is being currently investigated by a number of researchers. The focus of this paper is on characterization of pairs of aggregation operators that are satisfying distributivity law where one of them is a commutative, associative aggregation operator ...

Some Free Boundary Problems involving Nonlocal Diffusion and Aggregation
, 2015 We report on recent progress in the study of evolution processes involving degenerate parabolic equations what may exhibit free boundaries. The equations we have selected follow to recent trends in diffusion theory: considering anomalous diffusion with ...

Indicators for the characterization of discrete Choquet integrals [PDF]
, 2014 Ordered weighted averaging (OWA) operators and their extensions are powerful tools used in numerous decision-making problems. This class of operator belongs to a more general family of aggregation operators, understood as discrete Choquet integrals ...
