| 摘 要： | 本文针对不可量化因素对军机备件需求量的影响,提出了基于粗糙集的备件需求量的修正方法。考虑不可量化因素存在多值性的问题,将不可分辨关系下的经典粗糙集方法拓展成相容关系下的扩展粗糙集方法,通过相容关系下的近似空间获取决策规则,再由决策规则得到修正系数。最后以轮胎类器材为例,说明了修正系数的获取过程。

| Abstract: | In the paper,a modified method for spares demand of military aircraft based on rough sets theory is proposed to the effect of non-quantitative factors on the spares demand of military aircraft.Considering the multi-value properties of non-quantitative factors,original rough sets theory with indiscernibility relation is replaced by the extended rough sets theory with tolerant relation.By approximation space under tolerant relation,the decision rules are acquired,and then the modified coefficients are obtained through the decision rules.Finally,the obtained process of modified coefficients is illuminated by an example of tyre spares. |

| Keywords: | spares of military aircraft demand rough sets tolerant relation modified coefficients |
