Evaluation of performance of different units of Water and Wastewater Company using DEA

In this paper, the performance of [different] units of Water and Sewage Company in Isfahan Province was evaluated using Data Envelopment Analysis (DEA). 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.
