May 01, 2013· As we can see, depending on the particular type of aggregation operator used, the values S, R and Q are different. Note that the optimal choice would be the alternative with the lowest value of Q in each method. For most of the cases, the best alternative according to the values of Q is A 1 because it seems to be the one with the lowest distance to the ideal material.

Aggregation methods in group decision making: a decade

Mar 01, 2017· A very common aggregation operator is the ordered weighted averaging (OWA) operator which provides a parameterized family aggregation operator between the minimum, the maximum, the arithmetic average, and the median criteria whose originally introduced by Yager [27]. There are two features have been used to characterize the OWA operators.

In this spirit, if the number of input values is fixed, say n, an aggregation operator is a real function of n variables. This is still a too general topic. Therefore we restrict our considerations regarding inputs as well as outputs to some fixed interval (scale) I = [a, b] ⊑ [-∞, ∞]. It is a matter of rescaling to fix I = [0,1].
