Research on the comprehensive evaluation of coal blending and mixed burning effects based on AHP-CRITIC game theory combination weighting
In order to improve the accuracy and rationality of coal blending and mixed burning effect evaluation,a comprehensive evaluation system covering three dimensions of safety,economy and environmental protection,as well as 13 evaluation indicators,has been established.The analytic hierarchy process(AHP)and CRITIC weighting method were used to obtain the subjective and objective weights of each indicator,and the game theory combination weighting method was applied to optimize the weight allocation,determine the combination weights,and obtain the evaluation level and score of each coal blending scheme by combining with the fuzzy comprehensive evaluation method,and the main indicators affecting the effectiveness of coal blending and mixed burning were identified finally through obstacle analysis.The results showed that environmental indicators and safety indicators were important influencing factors for the effectiveness of coal blending and mixed burning,and optimizing these indicators could improve the operating level of coal-fired units.The proposed evaluation model provides decision support for power plant managers,promotes the development of the thermal power industry towards low-carbon and green direction.
