灰色关联判别分析模型及其应用

A Model of Distinguishing and Analysing Fuzzy Correlation and Its Application

本文针对模糊评价判别分析模型中多指标、多等级的判别分析问题，模糊隶属函数形式及参数的确定由于受主观因素作用，可能会丢失有用客观信息的缺陷，提出了一种将灰色关联度转化为灰色贴近度的灰色关联判别分析模型，该模型是对灰色关联度判别分析模型的修正，也是关联分析法和判别法的综合运用，因此是确定多指标、多等级条件下，判别被评对象所属等级的一种新方法。

Aiming at gray evaluating and distinguishing analysis models and problems on multi-variable and multi-rank's distinguishing, the authors provide a kind of gray correlation analysis model, in which gray correlation degree is converted into gray affinity degree. It supplies a gap of useful information's lose, which maybe likely caused by subjective factors' affection on specification of gray dependent function and decision of parameters. The model revises the gray correlation degree distinguishing analysis model and is integrative application of both correlation analysis and distinguishing analysis, hence it is a new method to ascertain the rank which the evaluated object belongs to, when multi-variables and multi-ranks are concerned.
