In this paper, an order induced by nullnorms on bounded lattices is given and discussed. We define the set of incomparable elements with respect to the order induced by a nullnorm. Also, by defining such an order, an equivalence relation on the class of nullnorms is defined and this equivalence is deeply investigated. (C) 2016 Elsevier B.V. All rights reserved.
