The assumption in DEA is that all inputs and outputs are definite, but in real situation , this assumption is not true. In this study, we suggest a model with fuzzy data called the fuzzy generalized DEA (FGDEA) model, which can treat the stated basic DEA models with fuzzy data in a unified way. In addition, we linearize this model.
