摘    要:为了改进灰色关联分析模型评价精度低的缺点,将熵值理论与灰色关联分析方法相结合,建立起基于熵权的灰色关联分析模型。根据各个指标值的变异程度,引用信息熵所反映数据本身的效用值来计算指标的权重系数,有效地避免了由于人的主观因素而形成的权重分配偏差。模型在区域雨水资源开发利用潜力综合评价中的分析结果表明:将熵值理论引入到灰色关联分析模型中是科学的,所建立的模型是合理的,能够提高灰色关联分析模型的评价精度。

关 键 词:熵权  灰色关联分析  综合评价

Abstract:In order to improve on the low evaluation precision of the grey relational analysis model,the entropy theory was integrated with the grey relational analysis method to establish a new model.According to the variation of each index,the weight coefficients in the model are derived from the avail value of data reflected by the information entropy,the subjective influence of weight allocation can be avoided effectively.The new model was applied into the comprehensive evaluation on exploration potentiality of regional rainwater resources,the analysis results have shown introducing the entropy theory into grey relational analysis method was scientific,the proposed model was reasonable and the evaluation precision of the grey relational analysis method can be increased.
Keywords:weighted entropy  grey relational analysis  comprehensive evaluation
