Abstract
There are several schemes for outgoing line utilization after implementation of energy conservation and emission reduction policy by "replacing small units with large ones". Therefore , a practical and effective evaluation method is urgently needed for evaluation and decision-making assistance. The attribute recognition theory is used to set up evaluation progress; the comprehensive weight of index is determined by combining variation coefficient method with expert weighting method; the category each scheme belongs to is identified according to confidence criterion. The example calculation shows that application of attribute recognition theo-ry can combine the quantitative index with qualitative index well;comprehensive weight can reflect subjective and objective influence of index; the method proposed can effectively evaluate outgoing line utilization schemes. The sensitivity analysis indicates that different composition ratio of comprehensive index weights may affect evaluation results of some special utilization schemes , to which special attention should be paid when the evaluation method is put into concrete application.关键词
