The theory of aggregation operators is a rapidly developing domain, supported by the use of aggregation concepts when modelling different engineering, economical, social, etc., problems. However, there is no unified notation in this field. Most of the results are disseminated in different papers or specialized monographs, where usually a specific dass of aggregation operators is discussed. This is, for example, the case of RR Yager's and J. Kacprzyk's edited volume dedicated to OWA operators in 1997 and of the monograph of E.P. Klement, R Mesiar and E. Pap (2000) devoted to triangular norms.
