In this sense, the notion of stability for a family of aggregation operators is inspired in continuity, though our approach fo-cuses in the cardinality of the data rather than in the data itself, so it is possible to assure some ro-bustness in the result of the aggregation

(PDF) A Discussion on Aggregation Operators J. Montero

In our opinion, an aggregation rule should never be understood just as a family of n-ary operators: all those aggregation operators must be deeply related, following some building procedure all throughout the aggregation process. There must be some unifying idea behind, and not only a mathematical expression with no particular meaning for users.
