Thus, we obtain some proposed methods given by Ertuğrul, Karaçal, Mesiar (Int J Intell Syst 30: 807–817, 2015) and Aşıcı, Mesiar (Int J General Syst 49: 143–160, 2020) as results. Also, for clarity we give some illustrative examples. Furthermore, we show that the new construction methods can be generalized by induction to a modified ordinal sum for t-norms and t-conorms on an appropriate bounded lattice, respectively.
