Navy combat search and rescue (NCSAR) is an important component of the modern maritime warfare and the scenario of NCSAR is the basis for decision makers to rely on. According to the core elements in the NCSAR process, the NCSAR scenario structure is constructed from seven perspectives based on the multi-view architecture framework. According to the NCSAR scenarios evolution over time, the NCSAR scenario sequence is analyzed and modeled based on the concept lattice method. Then, the incremental construction algorithm of the NCSAR scenario sequence lattice is given. On this basis, the similarity measurement index of NCSAR scenarios is defined, and the similarity measurement model of NCSAR scenarios is proposed. Finally, the rationality of the method is verified by an example analysis. The NCSAR scenario and similarity measurement method proposed can provide scientific guidance for rapid making, dynamic adjustment and implementation of the NCSAR program, and thus improve the efficiency and effectiveness of NCSAR.

一种海军作战搜救场景构建与相似度度量方法

海军作战搜救（NCSAR）是现代海战的重要组成部分，NCSAR的情景是决策者依赖的基础。根据NCSAR过程中的核心要素，基于多视图架构框架，从七个角度构建NCSAR场景结构。根据NCSAR场景随时间的演变，基于概念格方法对NCSAR场景序列进行分析和建模。然后，给出了NCSAR场景序列格的增量构建算法。在此基础上，定义了NCSAR场景的相似度度量指标，提出了NCSAR场景的相似度度量模型。最后通过算例分析验证了该方法的合理性。
