卫星应用任务分解规则库建立及匹配算法

卫星应用任务的分解是准确分析航天信息系统使命任务的关键步骤,为此需要对任务的分解建立标准的规则库.文章基于Disciple代理的知识表达方法,建立了卫星应用任务的分解规则库;然后通过一般化的概念对任务和规则进行分析,提出了一种任务匹配规则库的算法.文章以卫星应用中典型的侦察任务为例,探讨了规则库的建立和匹配.可以看出Disciple灵活的表达可以有效地描述好所涉及对象及其之间的关系,满足规则库建立的需要.

The Foundation and Matching Algorithm of Task Decomposition Rule Base in Satellite Application

Because the task decomposition in satellite application is the key process for analyzing task correctly,it is needed to found a standard task decomposition Rule Base.Based on Disciple,an expression method of agent knowledge,this paper builds a task decomposition Rule Base for the satellite application and puts forward a task matching algorithm using the concept of generalization which can analyse the relationship between task and rule.In the case of typical recon task of satellite application,this paper makes an attempt to found and match the Rule Base.The result indicates that Disciple's flexible expression can depict the related objects and their relation effectively and meet the requirement of the foundation of Rule Base.
