摘要
主要分析了数据标准化方法对综合评价加权求和法结论的影响;发现数据标准化方法对评价结论的影响主要体现在两个方面,一是使某些属性值无法参与计算,一是改变了属性间恒定的相互置换率;通过设定满足一定比例要求的理想解,可以消除数据标准化方法对加权和法评价结论的影响,获得一致的评价结论.
This paper mainly analyzes the influence of data standardization in weighted sum model; it is found that data standardization affect the evaluation result in two ways, one is make some datum lose value in the model, another is change the constant relative tradeoffs between attributes; To get a consistent result, it is suggested to set the ideal solution with certain proportion to eliminate the influence of data standardization.
