Recently, Srinivasan [On solving fuzzy linear fractional programming in
material aspects, Materials Today: Proceedings,
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.
