In this paper, we discuss how to deal with decision problems that are described with linear programming models and formulated with element of imprecision and uncertainty. More precisely, we will study linear programming models in which the parameters are not fully known but only with some degree of precision. In this research, a fuzzy flexible linear programming problem where with fuzzy objective coefficients and interval coefficient matrix is introduced. A solving process as well as Two-Phase the is established to solve these problems.
