In this paper, uninorms on bounded lattices are studied. Based on the existence a t-norm T-e acting on [0, e] and a t-conorm S-e acting on [e, 1], we propose some construction methods for uninorms on a bounded lattice L, where some additional conditions on the element e is an element of L\{0, 1} considered as an identity are required. The role of these additional conditions is stressed, as then our constructions yield a uninorm only in particular cases. When the idempotent t-norm T-e and the idempotent t-conorm S-e are considered, our methods give new types of idempotent uninorms on L. (C) 2019 Elsevier Inc. All rights reserved.
