Note on “Fuzzy multi-granulation decision-theoretic rough sets based on fuzzy preference relation”

  • 7 Accesses

Abstract

In this note, we point out that the transfer function for computing the fuzzy preference degree in Mandal and Ranadive (Soft Comput, 2018. https://doi.org/10.1007/s00500-018-3411-7) for the construction of upward/downward fuzzy relations is not additive consistent. Appropriate counterexample is given. Further, their modified versions are presented.
