“…While some of the similarity-distance measures have low performance indexes [16,19,20], the ones in [15,17,25] do not take account of the three parameters of IFSs, which adversely influence the performance rating of the similarity-distance measures. The motivation for this work is to propose a robust similarity-distance measure under intuitionistic fuzzy environment, with better performance rating compare to the techniques in [15,16,17,19,20,35]. Specifically, this paper i. revisits certain existing similarity-distance techniques between IFSs, ii.…”
