De ciencies Of Fuzzy Approaches To Solve Multiobjective Linear Fractional Programming Problems

The present paper reviews fuzzy approaches, for solving multiobjec- tive linear fractional programming problems (MOLFPPs). Di erent approaches dealing with fuzzy objective on a crisp constraint set are reviewed, and shortcomings of them are pointed out. Luhandjula used fuzzy approach to solve MOLFPP. Dutta et al. based on this approach formulated a linear programming problem to solve MOLFPP. Stancu and Pop showed that approach of Dutta et al. has shortcoming, and they modi ed their approach to get an e cient solution. In this pa- per it is indicated that results of Stancu and Pop has also shortcoming. Cakraborty and Gupta introduced a multiobjective linear programming to solve MOLFPP. The aim of this paper is to indicate that their ap- proach has again shortcoming, and it is not a successful method to lin- earize MOLFPP
