基于熵权法和G1法的大坝监测指标权重融合

Weight Fusion of Dam Monitoring Indexes Based on Entropy and G1 Methods

熵权法求权重能客观地反映实测信息,但不能反映专家意见,而G1法可反映专家的以往经验,但偏于主观。根据熵权法与G1法理论,综合了两种赋权方法,提出一种主客观相融合的大坝监测指标权重融合法,该法简单易行,计算结果较合理。

Weights obtained by entropy method can objectively reflect observation information but not reflect expert＇s opinions.G1 method can consider expert＇s experiences while it is inclined to subjectivity.According to the entropy method and G1 method,this article integrates two methods and puts forward weight fusion method of dam monitoring indexes.This method is simple and the calculation results are more reasonable.
