Performance Evaluation of coal enterprises energy conservation and reduction of pollutant emissions base on GRD-TOPSIS

For the performance evaluation of coal enterprises energy conservation and reduction of pollutant emission, a new GRD-TOPSIS method is proposed. By analyzing the background of performance evaluation of energy conservation and reduction of pollutant emission, the performance evaluation system of coal enterprises is established. Three coal enterprises of Yanzhou City are selected as evaluation objects, and use the new method to evaluate their performance of energy conservation and reduction of pollutant emission. The practical example shows the feasibility and effectiveness of the proposed method.KeywodsGRD-TOPSIS; MADM; energy conservation and reduction of pollutant emission
