| 摘 要： | 基于信息熵，构建了“典型排序”在模糊集上的隶属函数，证明了构建方式的合理性，是一种结合德尔斐专家调查法和熵权法的分析方法，且构造方式简单。利用信息转换参量，将“典型排序”转化为度量指标信息的相对重要性系数。结合电力通信系统评价指标体系，讨论了信息转化过程中“转化失真”对权重的影响，通过信息转化参量的最优取值减小了失真，计算并讨论了可靠性综合指数及其意义。 |

| Abstract: | This paper constructs the membership function of quantitative order in the fuzzy set based on the information entropy, and proves the rationality of construction way. It is a kind of analysis method, which combines Delphi method and entropy weight method. And it has simple mode of construction. By the information conversion, it translates the quantitative order into the relative importance factor parameter. Based on the evaluation index of electric power communication system, this paper discusses the influence of conversion distortion during the information transformation. Through the optimal value of information transformation parameter, it reduces the distortion, calculates and discusses the reliability of composite index. |
