摘　　要：针对我国近期电源点逐步到役的情况,提出1种基于改进模糊层次法和熵权法的评估方法。首先基于层次分析法构建合适的层次结构,形成判断矩阵。随后利用模糊层次分析法对各层级之间的判断矩阵进行处理,得出面向重要性的权重向量。同时采用德尔菲调查法形成最末一级子准则层与目标层的评估矩阵,经归一化处理后利用熵权法求得面向价值性的权值向量。然后把2种权值向量经过综合化处理,形成综合权重向量。最后形成方案层对目标层的最终权重向量,得出推荐意见。通过算例,证明该评价方法灵活性强,适用性广,过程清晰合理,结果直观准确。In view of the recent situation in which power sources gradually reach their service terms in China,an evaluation method based on improved fuzzy analytical hierarchy process(FAHP)and entropy weight method(EWM)is proposed.First,an appropriate hierarchical structure is constructed based on the analytic hierarchy process to form a judgment matrix.Then,FAHP is used to process the judgment matrix between various layers,and the importance-oriented weight vector is obtained.At the same time,the Delphi survey method is used to form an evaluation matrix for the last sub criterion layer and the target layer.After normalization,EWM is used to obtain the value-oriented weight vector.The two weight vectors are synthesized to form a comprehensive weight vector.Finally,the final weight vector of the scheme layer to the target layer is formed,and the best scheme is given.The result of an example shows that the proposed evaluation method has strong flexibility and wide applicability.In addition,it also has a clear and reasonable process,as well as intuitive and accurate results.
