“…However, one potential drawback of the aforementioned operators is that the results are sensitive to the value of an operator-related parameter, and a minor change in the value of this parameter could reflect significant variations in the final decision. Similar concerns are associated with various other well-known operators such as Dombi's operator [5,6], Hamacher's operator [7], Frank's operator [8], Weber's operators [9], Dubois and Prade's operator [10], and Schweizer's operator [11], among many others. However, one operator, namely the Einstein operator, does not suffer from the drawback, since there is no operatorrelated parameter associated with that.…”
