摘要
对灰色系统关联分析的数据标准化方法进行了分类讨论,认为在水质评价分级应用中,传统的标准化方法给结果带来多解性以及人为确定解的困难。进一步提出了同单位化、仅作垂向平移的数据处理方法,其解是唯一的,不带有人为选择问题,并通过实例证明了所提方法的合理性及可信性。
This paper discusses the classification of the method for data standardization of grey relational analysis. It is considered that the old standard method would get varied answers on water quality evalution. It is further suggested that a new method of the same unit and only the vertical translation is able to get a only answer and keep away artificial answers. By an example, the paper proves the suggested method is reasonable and feasible.
