In this paper, we propose construction methods for triangular norms (t-norms) and triangular conorms (t-conorms) on bounded lattices by us-ing interior and closure operators, respectively. Thus, we obtain some proposed methods given by Ertugrul, Kara,cal, Mesiar [15] and C,ayli [8] as results. Also, we give some illustrative ex-amples. Finally, we conclude that the introduced construction methods can not be generalized by induction to a modified ordinal sum for t-norms and t-conorms on bounded lattices.eninfo:eu-repo/semantics/openAccesst-normt-conormordinal sumbounded latticeArticle10.14736/kyb-2022-3-0456583456478WOS:0008746439000092-s2.0-85145938150Q4Q3
