The purpose of this study was to provide a clear picture of the relative performance of Decision-Making Units (DMUs) in 2018. The advantage of using the DEA model over parametric models is to measure the performance of units using specific weights. In this study, data were collected through desk studies, and then, analyzed using mathematical modeling (linear programming). MATLAB was used to analyze the data indicating that 11 out of 30 units were efficient and the rest were inefficient. CP - IRAN IN - LG - eng PB - IJAORLU PG - 21 PT - Research YR - 2019
