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
