Some t-conorm-based distance measures and knowledge measures for Pythagorean fuzzy sets with their application in decision-making

Abstract The Pythagorean fuzzy sets are more robust than and intuitionistic in dealing with the problems involving uncertainty. To compare two sets, distance measures play a crucial role. In this paper, we have proposed some novel for using t-conorms. We also discussed their various desirable properties. With help of suggested measures, introduced new knowledge sets. Through numerical comparison linguistic hedges, established effectiveness respectively, over existing setting. At last, demonstrated application pattern analysis multi-attribute decision-making.
