评价方案择优的灰关联分析方法

Selecting Optimum from Evaluation Schemes Using Grey Relational Analysis

针对多方案评价时采用不同评价方案对同一评价对象进行评价,评价结果不一致这一问题,引入兼容度和差异度两个衡量评价方案优劣的指标,并依据灰关联理论,提出采用方案靶心度作为评价方案优劣的根据.实际应用结果表明,该方法能够加大评价方案优劣的区分度,能够快速准确地选出合理的评价方案.

In order to solve the inconsistence of the evaluation results when we use different methods to evaluate the same evaluation object. We present two indexes of Compatibility Degree and Difference Degree, which are used to judge good or bad of the evaluation method. Then according to Grey Relational Theory, we use Approaching Degree to select optimum from evaluation schemes. In the practice, we find that this method not only can enlarge the differences of different evaluation methods but can be easily used and have a high accuracy degree.
