| Abstract | ||||
| In this paper, a new method for solving multiobjective linear fractional programming problems with rough coefficient (MORLFP) is proposed. The MORLFP problem is considered by incorporating rough intervals in the coefficients of the objective functions. It is provided that a MORLFP problem is converted to an optimization problem with rough interval valued objective functions which it their bounds are four multiobjective linear fractional functions. The rough efficient solutions are characterized by using a new proposed algorithm. A numerical example is given for the sake of illustration | ||||
