针对武器装备数据多为小样本情况,采用灰色关联度对其研制生产费用影响因素的确定,针对灰色关联度不能处理负相关和组合相关的问题,提出应用普通相关和逐步回归对灰色关联度结果进行修正,实例分析表明处理结果更符合实际情况. Aiming at the fact that the data of weaponry equipment are mostly small, the author uses the gray relational degree to determine the influencing factors of the research and production costs. In view of the fact that the gray relational degree can not deal with the negative correlation and the combination correlation, this paper puts forward that using the common correlation and the stepwise regression to the gray relational result To be amended, the case analysis shows that the treatment results more in line with the actual situation.
