权向量的一般模型与权确定方法的分析

A General Model of Weight Vectors and Analysis of Weight Assigning Methods

结合效用理论与因素空间理论 ,首先给出了权向量的数学描述与一般模型 ,接着运用此模型对常用的权确定方法加以分析 ,指明常用方法的缺陷在于主、客观信息的分离 。

Based upon the utility theory and the factor spaces theory,this paper presents a mathematical description and a general model of weight vectors,then points out the disadvantages of generally used weight assigning methods,finally provides two methods overcoming the shortcomings.
