基于熵权法与灰色关联度法的煤矿企业信息化水平评价

针对常用的信息化水平评价方法采用专家打分方式确定指标权重而导致评价主观性过强的问题,提出一种基于熵权法与灰色关联度法的煤矿企业信息化水平评价方法。该方法根据煤矿企业的特点以及信息化对煤矿企业的作用,将煤矿企业信息化评价指标体系划分为5个一级指标和19个二级指标;采用熵权法确定指标权重大小,并采用灰色关联度法计算评价对象与参考数列的关联度,根据关联度大小确定信息化水平等级。运用该方法对某煤矿信息化水平进行评价,结果表明,该方法能客观、准确地反映煤矿企业信息化水平的实际情况。

Evaluation of Coal Mine Informatization Level Based on Entropy Weight Method and Grey Correlation Degree Method

In allusion to the problem of excessive experience dependence of common evaluation methods of informatization level which use expert scoring method to determine index weight,the paper proposed an evaluation method of informatization level of coal mine based on entropy weight method and grey correlation degree method.The evaluation method divides the evaluation system into 5 primary indexes and 19 secondary indexes,uses entropy weight method to determine value of index weight,uses grey correlation degree method to calculate correlation degree of evaluated object and reference sequence,and determines informatization level according to the correlation degree.Using the proposed method to evaluate informatization level of a coal mine,the results showed that the method can reflect actual situation of informatization level of the coal mine objectively and accurately.
