The study of efficiency measurement was pioneered by Farnell in 1957. Since then, researchers in this field have developed many models to measure the efficiency of firms. However, there is no universally acceptable model to measure the efficiency of electric utilities due to differences in the selection of measures, countries’ socioeconomic structures, as well as quality and availability of data.
The purpose of this study was to measure and rank the efficiency of electric utilities using a Three-Stage Data Envelopment Analysis-Artificial Neural Network (3S DEA-ANN) model. The model is developed using R programming and RStudio software.
