اPerformance Assessment of South Fars Power Generation Management Company by using of Data Envelopment Analysis with Interval Data and Undesirable Outputs

Due to the power industry importance in the process of country economic development, studying the efficiency of power plant s is very important. By measuring the efficiency can be perceived the strength and awareness of different sectors and can improve their performance by provide the appropriate solutions. In this paper, power plants was assumed as a decision-making unit that consume gas and gasoline fuel as input to generate electricity production and pollutant gases as desirable and undesirable outputs respectively. In this research, we discussed to measure the technical efficiency of power plants in power generation Management Company of Jonoob-e-Fars since 2010 to 2014, by using the DEA with interval data and undesirable outputs. We got results and finally, we determined the efficient and inefficient units by implementation of all the proposed models of DEA in different technologies. In the following, we determine rank of units by using of topsis and Shannon’s entropy methods and discussed to determine the most economic rates of industry plants and provide the scientific proposal to improve the efficiency of the unit ineffective decision-making units.
