A COMPREHENSIVE EVALUATION METHOD OF WASTE INCINERATION POWER PLANT BASED ON DELPHI METHOD AND TOPSIS METHOD

The current evaluation standard of domestic waste incineration plants is based on the project construction level and operation management level of the evaluation object. Then comprehensive scoring method is conducted according to the different weights of the two dimensions. Due to the large differences in design parameters between waste incineration power plants, the existing evaluation methods are mainly based on design parameters, and the evaluation objects are evaluated by experts. Index selection doesn't consider the weights from the perspective of energy efficiency and environmental protection indicators, and the expert scoring also has strong subjectivity. Therefore, the evaluation results are one-sided sometimes. By using the Delphi and TOPSIS method and combining them reasonably, this paper gave a comprehensive evaluation method from the aspects of index determination, index evaluation and ranking different planets. First, using the Delphi method, the evaluation indicators were determined from the perspective of energy efficiency and environmental protection, so that the evaluation dimensions gave consideration to both economic and social aspects. Then, using Delphi method, experts ranked the evaluation objects according to the determined evaluation indicators to give the subjective score. The deviation between the actual evaluation index and the ideal solution was objectively scored by the TOPSIS method. The final comprehensive score was calculated according to the different weights of subjective and objective evaluations. This method was proposed to evaluate the operation of multiple waste incineration plants and provide a subjective and objective ranking. It can provide new scoring ideas for the revision of the current evaluation standards for domestic waste incineration plants.
