摘要

In this paper, we introduce two approaches for obtaining new classes of uninorms using the uninorm defined on a sublattice [0, k] (or [t, 1] ) of a bounded lattice L with a neutral element \(e\in ] 0,k[ \) e ] 0 , k [ (or \(e\in ] t,1[ \) e ] t , 1 [ ) . As a by-product, these tools encompass some of the existing construction methods for uninorms on L. Moreover, we provide some examples to assess the differences between our methods and the existing approaches.
