Environmental Performance Evaluation of Thermal Power Plant with Variable Weight Coefficient and Fuzzy Pattern Recognition

Environmental performance evaluation is a multi-attribute evaluation problem. The determination of indicators’ weight is the key problem in the multi-attributes evaluation. This paper set up an evaluation model based on multi-attribute variable coefficients and fuzzy pattern recognition aimed at a thermal power plant. The model gives full play to the advantages of the subjective and the objective coefficients and enables itself to alter the coefficients in accordance with the specific indicator values of evaluated objects, hence, bringing the function of performance evaluation into full play.
