Hierarchies of aggregation operators

International Journal of Intelligent Systems, 1994
This article deals with hierarchies of operators. In particular, we will analyze the problem of amalgamating individual opinions into a single group opinion, based upon hierarchical intensity aggregation rules. Our main goal is to decide whether hierarchical amalgamations are supported from an ethical and rational point of view.

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.

DIVERGENCE MEASURES AND AGGREGATION OPERATIONS [PDF]

open access: possibleInternational Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2000
In this paper we study the relations between divergence measures of two fuzzy sets and other well-known functions, namely aggregation operations and measures of fuzziness. We will show that these functions can be related. Therefore, we study some consequences of these properties as an application; indeed, we obtain some special cases of divergence ...

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.
