基于混合相似度的反导作战案例检索方法

Case Retrieval Method of Antimissile Operation Based on Hybrid Similarity

针对反导作战预案属性种类繁多、元素复杂等特性,为了更好地将作战预案与作战问题进行匹配,分析了反导作战预案各属性的差异,设计了一种先局部后整体的相似度量策略,将反导作战预案属性划分为关键类属性、裕度值属性、确定性数值属性、区间性数值属性、模糊属性和文本类属性6类,并给出了相应的相似度量算法。基于最近邻策略,提出了一种基于混合相似度的反导作战案例检索方法,并对该方法进行了实例验证,结果表明:该方法能有效提高反导作战案例检索的速度和正确率,可为反导指挥控制系统的建设提供技术支持。

According to the characteristics of the antimissile operation plan,such as various kinds of attributes and complex elements,in order to better match the operation plan with the operational issues,based on the analysis of each antimissile operation preplan differences,a similarity measure strategy that computes the whole case similarity after the partial one is designed. The antimissile operation plan attribute is classified into six kinds such as key attribute,margin value attribute,deterministic numerical attribute,interval numerical attribute,fuzzy attribute and semantically attribute,and corresponding similarity measure methods are presented. Based on the nearest neighbor strategy,a new case retrieval method of antimissile operation based on hybrid similarity is designed,and it is verified by the case example. The result shows that the method can improve the speed and the accuracy of case retrieval,which provides technical support for the construction of antimissile command and control system.
