On Conjunctive and Disjunctive Rational Bivariate Aggregation Functions of Degrees (2,1)

In the last decades, many families of aggregation functions have been presented playing a fundamental role in research fields such as decision making, fuzzy mathematical morphology, etc. For this reason, it is necessary to study different types operators be potentially used concrete application well properties they can satisfy. paper, conjunctive and disjunctive rational bivariate degree two numerator one denominator are studied. particular, characterization degrees (2,1) presented. Moreover, symmetry property these investigated.
