On Yager's aggregation operators

[1992] Proceedings The Twenty-Second International Symposium on Multiple-Valued Logic, 2003
R.R. Yager (1988) introduced a special type of aggregation operator, OWA operators, and applied them to multicriterion decision-making. An alternative definition of such operators is given. and their structural properties are investigated in some detail. >

Aggregation Operators and Additive Generators

International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2001
Generated aggregation operators on continuous and discrete scales derived by means of a generating system are introduced. Linear generating systems are shown to be equivalent with the class of weighted means. The following classes are characterized: symmetric generated aggregation operators, idempotent generated aggregation operators, generated ...

ASYMPTOTICALLY IDEMPOTENT AGGREGATION OPERATORS

International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2009
This paper deals with aggregation operators. A new form of idempotency, called asymptotic idempotency, is introduced. A critical discussion of the basic notion of aggregation operator, strictly connected with asymptotic idempotency, is provided. Some general construction methods of symmetric, asymptotically idempotent aggregation operators admitting a

Weak uninorm aggregation operators

Information Sciences, 2000
By weakening the identity condition for uninorms, a general class of associative aggregation operators, called weak uninorms, is introduced. It is proved that a continuous weak uninorm is a combination of a continuous t-norm and a continuous t-conorm through a median operator.

Aggregate operators in probabilistic databases

Journal of the ACM, 2005
Though extensions to the relational data model have been proposed in order to handle probabilistic information, there has been very little work to date on handling aggregate operators in such databases. In this article, we present a very general notion of an aggregate operator and show how classical aggregation operators (such as COUNT, SUM, etc.) as ...
