A comment on "a novel parametric ranking method for intuitionistic fuzzy numbers"

Roohollah Abbasi Shureshjani; Bita Shakouri

Volume 1, Issue 3 , September 2021, , Pages 156-160


  This note shows that the parametric ranking method proposed by Darehmiraki [M. Darehmiraki, A novel parametric ranking method for intuitionistic fuzzy numbers, Iranian Journal of Fuzzy Systems, 16(1) (2019), 129-143] is not correct. By two appropriate examples, we show that the developed index for ranking ...  Read More

Optimization of fuzzy linear fractional programming problem with fuzzy numbers

Sapan Kumar Das

Volume 1, Issue 1 , March 2021, , Pages 30-35


  In this paper, we consider a Fuzzy Linear Fractional Programming (FLFP) problem under the condition that the objective function and the values of the right-hand side are represented by symmetric trapezoidal fuzzy numbers while the left-hand side constraints are represented by real numbers. Decision variables ...  Read More
