聚类分析和判别分析在安全评价中的综合应用

Comprehensive Application of Cluster Analysis and Discriminant Analysis in Safety Assessment

将多元统计方法中的聚类分析和Fisher判别分析综合应用于安全评价中,评价指标的系统效应权数有效避免了安全评价中人为赋予指标权重对评价结果的影响。分析了评价对象聚类的步骤和结果,探讨了评价对象所属安全等级的Fisher判别方法。最后通过对判别函数的分析与比较得出评价判别结果。

Two analysis methods,cluster analysis and discriminant analysis are comprehensively applied in safety assessment.The comprehensive affecting weighting coefficient of indexes has avoided the bad influence of the application of human weighting coefficient in safety assessment.The stages and result of cluster are analyzed and the Fisher discriminant method is studied to discriminate the safety class of the object.At last the assessment results are given by analyzing discriminant function.
