摘　　要：结合阈值变权的思想提出了一种基于指标白化权函数值的灰色聚类方法,采用阈值原则对属性间的灰色属性关联矩阵进行标准化使得属性权重分配更加符合实际问题的需要.最后建立了某资产管理公司的项目评估决策模型,验证了模型的客观性与有效性.First by means of a threshold weights theory, a method based on maximizing variances of the index whitenization weighting function is proposed, which has combined a threshold rule. The grey relationship matrix is obtained and by the standardization of grey relationship matrix, the effective relationship matrix could be obtained. Finally, the objectivity and validity of this model has been werified through the solution of an example to the model.
