Abstract

In this paper, we propose novel methods for constructing uninorms using two comparable closure operators or, alternatively, two comparable interior operators on bounded lattices. These methods are developed under the necessary and sufficient conditions imposed on these operators. Specifically, the construction of uninorms for (x ,y )∈ ]0 ,e [×]e ,1 [ ∪ ]e ,1 [×]0 ,e [ depends not only on the structure of the bounded lattices but also on the chosen closure operators (or interior operators). Consequently, the resulting uninorms do not necessarily belong to U_min^*∪ U_min¹ (or U_max^*\cupU_max⁰). Moreover, we present the degenerate cases of the aforementioned results, which are constructed using only a single closure operator or a single interior operator. Some of these cases correspond to well-known results documented in the literature.
