EVALUATION INDEX SYSTEM FOR PERFORMANCE EVALUATION OF ECOINDUSTRIAL THERMAL POWER PLANTS BY USING FUZZY DELPHI METHOD

In order to promote the clean and sustainable production of coal resources, more and more eco-industrial thermal power plants (ETPPs) are established in China. Considering it is a burgeoning industry, the performance evaluation and management of the eco-industrial thermal power plants is important to the construction and development. Therefore, a evaluation index system for eco-industrial thermal power plants is presented in this paper. Because ecoindustrial thermal power plants performs many tasks that should be measured by multiple criteria and requirements, Delphi method are involved to select the evaluation criteria. Moreover, in order to tolerate vagueness and ambiguity of subjective judgment, fuzzy theory is combined with the Delphi method in evaluation criteria determination process. Firstly, the initial evaluation criater are established based on circular economy theory, and then the fuzzy Delphi method is used to selected the final criteria. Finally, the fianal evaluation criteria contains of “Economy development,” “Energy utilization,” “Refuse recycle,” and “Pollutant emissions” four aspects and 13 sub-criteria. This study provides a comprehensive and effective method for evaluation criteria selection of eco-industrial thermal power plants and also innovates the utilization of fuzzy Delphi method.
