One of the most prevalent problems in linear programming as one of the convenient models in the field of operationس research environment is Data Envelopment Analysis (DEA), which supports the efficiency of Decision Making Units (DMUs). Usually, accurate data are common; however, in the real world, we are facing an Inaccurate situation. In this paper, a new model for assessing DMUs in a fuzzy environment is presented; we Consider the inverse DEA model with the variable return to scale with fuzzy numbers for fluctuating data. A case Study is given to illustrate its performance
