A centralized decision maker (DM) as supervises of its decision making units (DMUs), interest to minimizing the total input consumption and maximizing the total output production. This can be done by maximizing the efficiency of individual units using by conventional DEA models. This paper computes the models which used the above process for fuzzy data. We deal with linear programming problems with fuzzy parameters from the viewpoint of expert's imprecise or fuzzy understanding of the nature of parameters in a problem- formulation process and consider fuzzy linear programming arising from the linear programming problems. The advantages of these models are considered by examples
