基于概念格的航天任务态势要素提取

Research on the Extraction Method of Situational Elements of Space Mission Based on Concept Lattice

为满足航天指挥员军事需求,定制生成其关注的态势产品,提高决策时效性,针对航天任务态势融合环节中的态势要素提取问题,首先研究分析了态势要素提取原则和航天任务与态势要素之间的关系;其次,根据不同航天任务存在共同关注的态势要素集合,在要素提取过程中引入模块概念,根据要素之间的联系,构建了围绕不同功能主题的态势模块,确定任务内态势模块之间的层次结构;最后,基于概念格的方法提出对航天任务态势要素进行提取策略,并结合航天应急发射实例验证该方法的有效性。

In order to meet the military needs of aerospace commanders,customize the situation products they care about,and improve the timeliness of decision-making,this article focuses on the extraction of situation elements in the space mission situation integration link.Firstly,the principle of situation element extraction and the relationship between the space mission and situation elements are studied and analyzed;Secondly,there is a set of situation elements of common concern according to different space missions,and in the process of element extraction introduce the concept of modules,it builds situation modules around different functional themes according to the connections between elements,and determine the hierarchical structure between situation modules within the mission;Finally,a concept lattice-based method is proposed to extract the situation elements of aerospace missions,combined with aerospace an emergency launch example verifies the effectiveness of this method.
