New insight on solving fuzzy linear fractional programming in material aspects

Recently, Srinivasan [On solving fuzzy linear fractional programming in material aspects, Materials Today: Proceedings, https://doi.org/10.1016/ j.matpr.2019.04.209] proposed a method to solve fractional linear programming problem under fuzzy environment based on ranking and decomposition methods. Srinivasan also claimed that the proposed method solved fractional linear programming problem with inequality and equality constraints. In this note, we point out that the paper entitled above suffers from certain mathematical mistakes for solving these problems. Hence, the mentioned method and example are not valid. Further the exact method is stated and solved the problem.
