Abstract

It is the purpose of this article to introduce a new weighted FGP technique by using only under deviation variables to fuzzy goals of fuzzy multi objective linear fractional goal programming problem (FMOLFGPP) to achieve highest degree of each of the membership goals by minimizing their under deviational variables. To assess the relative importance of the fuzzy goals properly, the weighting scheme by the decision of decision maker (DM) and Mohamed’s technique (Fuzzy Sets and Systems, 89 (1997) 215-222) has been used. Illustrative numerical examples of FMOLFGPP are provided to demonstrate the feasibility of the proposed method, which clearly shows the proposed approach yields better optimal solution of FMOLFGP problem than the conventional min sum FGP approach in the sense that it gives the values of the fractional objectives closer to their aspiration level.
