Trapezoidal approximation and aggregation

Adrian Ban , Lucian Coroianu , Przemysław Grzegorzewski

Abstract

Trapezoidal approximation of fuzzy numbers is discussed in relation to data aggregation. An important problem whether it is better to simplify initial data before using an aggregation operator or conversely, to aggregate original fuzzy values and then to simplify the output is addressed.
