Several sufficient conditions are presented in order that the M-affine (continuous) functions corresponding to a (strict continuous) mean M be all affine functions.

The ordered weighted average (OWA) aggregation is an extension of the classical weighted average by using a reordering process of the arguments in a decreasing or increasing way. This article presents new averaging aggregation ...

The induced ordered weighted average is an averaging aggregation operator that provides a parameterized family of aggregation operators between the minimum and the maximum. This paper presents some new generalizations by ...
