基于熵权法和MADM的电力客户信用风险评价

电力客户的信用程度直接影响到供电企业的正常运营，也是保证我国电力工业健康发展的前提。因此，采用科学的方法对电力客户的信用进行评价具有重要的理论和现实意义。电力客户的信用风险评价是典型的多属性决策问题，决策者往往很难对每个评价指标赋予一个确定数值，但凭借经验可以给出大致范围。鉴于此，这篇论文在描述电力客户的各个属性值时采用了区间数的表示形式，随后，利用正态分布3σ原则，将区间数形式表示的属性值转化为单点值，运用熵权法确定出各评价指标的权重，最后计算各个电力客户的综合评价值并进行排序优选。实例研究结果表明这是一种科学实用的评价比较方法，为供电企业规避客户信用风险提供了重要的参考依据。

Evaluation of Electricity Customers' Credit Risk based on Entropy Method and MADM

The degree of power customers' credit can affect power supply enterprises' normal operation directly,it is also a premise to ensure the healthy development of China's power industry.Therefore,it has important theoretical and practical significance to evaluate power customer's credit by using a scientific method.The evaluation of electricity customers' credit risk is a typical multi-attribute decision-making problem,it is difficult for decision-makers to give a determinate value for each evaluation index,but...
