针对案例检索中属性或案例有变动时，属性权重无法实时更新的问题，本文提出一种基于属性重用度的权重确定方法。该方法将属性在问题建模求解时的重用程度引入属性权重的计算过程，以车辆路径问题类型案例库作为数据来源，并借助MATLAB编程测试了算法性能。结果表明，该方法在相似案例检索时具有更高的分辨率，且实现了案例库中案例属性权重的动态维护。

To solve the problem that in existing attribute weight determination method weight cannot be real-time updated when attributes or cases change in the case base,this paper proposes a weight determination method based on the reusability of attributes. This method introduces the reusability of attributes in problem modeling to the attribute weight calculated process,and gives a specific description of the algorithm,and implement the algorithm by MATLAB. The experimental results show that this method has a higher resolution in case retrieval,and realizes the dynamical maintenance of the case attribute weight in the case base.
