中文摘要：
针对空中目标威胁排序问题,提出了一种依据部分属性值即可对目标威胁进行快速排序的方法。首先选取具有代表性的样本数据作为案例库;然后确定条件属性和决策属性,在利用K-均值聚类算法对决策属性进行离散化后,提出了一种针对连续条件属性值的全局离散化方法,并对离散化后的案例库进行属性约简并得出决策规则;最后将待排序目标各属性值进行离散化后利用决策规则即可对目标进行威胁排序。通过算例说明该方法能够快速、有效地对空中目标进行威胁排序。
英文摘要：
For the threat sequencing of air attack targets,a method of fast threat sequencing based on certain attribute values was presented.First the representational sample data was chosen for cases;then the condition attributes and decision attributes were confirmed.Then after the decision conditions had been discretized by the method of K-means algorithm,a global discretization for the condition attributes were presented.At last,the attributes of cases were reduced and the decision rules were drawn.For the air attack targets,the threat sequencing can be gotten using the values which had been discretized and the decision rules which had been gotten.From the example,the conclusion can be drawn that it is a effective method.
