摘　　要：针对评价指标间的相关性关系难以突破的限制,提出一种基于局部保持投影分析的供应商分类方法,对供应商进行分类评价。以电力企业的轴承供应商为例进行局部保持投影分析,结果表明,在使用该方法对供应商进行分类时,设置合理的参数能够快速得到较为合理的供应商分类结果。In view of the limitation that the correlation between evaluation indexes is difficult to break through,a supplier classification method based on local preserving projection analysis is proposed to classify and evaluate suppliers.Taking the bearing suppliers of power enterprises as an example,the local preserving projection analysis is carried out.The results show that when using this method to classify suppliers,the reasonable supplier classification results can be obtained quickly by setting reasonable parameters.

关 键 词：供应商分类 电力企业 局部保持投影 Jaccard相似性系数
