摘要
提出了正交试验数据计算分析的新方法——灰关联分析法(Grey Relation Analysis,简称GRA)。应用GRA对不考虑交互作用的正交试验结果进行统计分析,得出各因素各水平对试验结果的关联度,从而确定因素的主次顺序以及最优试验条件。
A new method for statistically analyzing the data of the orthogonal trial, Grey Relation Analysis （GRA）, is put forward. Applying GRA to statistical analysis for the non-interacting orthogonal trial, the grey relation degrees of each factor for trial results are obtained, and the principal-secondary sequence of factors and the optimum trial condition are given.
