Abstract: In order to enhance the quality, Economic life and improving the reliability, In the attainment of electricity required supply, Performance evaluation of supervised (Generation, transmission and distribution above) each Regional Electricity Company As a challenge to be felt In Iran. This paper uses a three-stage DEA approach Data collected from 16 regional electricity companies During the 2006- 2013 period are evaluated and analyzed. One innovative aspect of this research Electricity Industry analysis DEA is a three-step approach . The study, by using a three-stage DEA The relative efficiency regional electricity companies with three different measures. Then the for measuring validity of the three models The effect of the independent variables (inputs and outputs of the model) The dependent variable (efficiency scores obtained by each model) Multiple regression was used. The results of the analysis of efficiency scores, The best model in three steps Generation, transmission and distribution of these shows. The average efficiency of 16 Regional Electricity Company of the year 2006 to 2011, a decreasing trend and from 2011 to 2013 has increasing trend. Regional electricity companies Tehran, Gilan and Khorasan highest efficiency rating and the regional electricity companies Sistan and Baluchistan, Mazandaran has the lowest efficiency rating in 2013 and also the results efficiency decomposition shows the transmission and the distribution the greatest impact on the overall efficiency of the regional electricity companies . |
