Applying the data envelopment analysis method for evaluating the efficiency of the complex system operations in fuel and energy companies

This work proposes the Data Envelopment Analysis method (DEA) as a tool for evaluating the efficiency of the complex systems operations on the example of fuel and energy companies. It is also presented a comparative analysis of different methods for evaluating the efficiency of the complex systems operations. The output-oriented DEA model is used in the research. The task with one input and two outputs is solved. In order to test the method, a complex system was chosen – the heat supply system for the heat and power plants on the left bank of Krasnoyarsk. The calculations were made using four heat and power plants in Krasnoyarsk
