Trapezoidal approximation and aggregation
Adrian Ban , Lucian Coroianu , Przemysław Grzegorzewski
AbstractTrapezoidal 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.
