In this work, we present several ways to obtain different types of weighting triangles, due to these types characterize some interesting properties of Extended Ordered Weighted Averaging operators, EOWA, and Extended Quasi–linear Weighted Mean, EQLWM, as well as of their reverse functions. We show that any quantifier determines an EOWA operator which is… (More)
Stability of aggregation operators is characterized and discussed. 1-stability turns to coincide with 1-Lipschitz p r o p erty. Several examples and basic results are given.
