Semiautoduality in a restricted family of aggregation operators

Fuzzy Sets and Systems, 2007
In this paper we consider aggregation operators satisfying non-decreasingness and some specific boundary conditions. We then analyze some properties of such a family of aggregation operators, introducing the semiautoduality condition, which is weaker ...

Strictly stable families of aggregation operators

Fuzzy Sets and Systems, 2013
In this paper we analyze the notion of family of aggregation operators (FAO), also refereed to as extended aggregation functions (EAF), i.e., a set of aggregation operators defined in the unit interval which aggregate several input values into a single ...

Logics with aggregate operators

Proceedings. 14th Symposium on Logic in Computer Science (Cat. No. PR00158), 2001
We study adding aggregate operators, such as summing up elements of a column of a relation, to logics with counting mechanisms. The primary motivation comes from database applications, where aggregate operators are present in all real life query languages.

Aggregation of OWA Operators

IEEE Transactions on Fuzzy Systems, 2018
Inspired by the real needs of group decision problems, aggregation of ordered weighted averaging (OWA) operators is studied and discussed. Our results can be applied for data acting on any real interval, such as the standard scales $[0,1]$ and $[0,\infty [$ , bipolar scales $[-1,1]$ and $\mathbb {R}=]-\infty, \infty [$ , etc.

Aggregation operators with annihilator

International Journal of General Systems, 2005
This paper is devoted to the study of a special kind of aggregation operators: commutative, non-decreasing binary operators F on [0,1] with annihilator and such that F(0,0) = 0 and F(1,1) = 1 . A characterization of this kind of operators is given, including many examples and properties in the general case.

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 ...
