Abstract: The shortcomings of traditional data processing techniques, characterised by their inherent uncertainty and ambiguity, give rise to flawed assessments of thermal power companies' carbon efficiency. Consequently, there is a pressing need for an innovative evaluation approach that leverages the fuzzy-AHP methodology. This method begins by scrutinising the essence of carbon performance metrics and the structural framework of thermal power businesses. It then proceeds to construct a comprehensive set of evaluation indicators for carbon performance. The fuzzy-AHP technique is employed to hierarchically organise the evaluation levels of carbon performance for thermal power enterprises. By integrating the weights of individual indicators and utilising a fuzzy evaluation matrix, this method calculates a cumulative carbon performance score, facilitating the comprehensive evaluation process. Experimental outcomes reveal that this method achieves an impressive accuracy rate of up to 98%, while simultaneously reducing the evaluation duration significantly.

Keywords: fuzzy-AHP; thermal power enterprises; carbon performance; grade evaluation.
