基于知识的景象适配性分析决策系统

文章考察了目前选择景象匹配区的准则的缺陷,阐述了景象适配性分析方法应该综合考虑景象的独特性度量值、时效性特征、专家经验知识、末段飞行约束条件等因素。将基准图的特征结合匹配概率估计值表达成决策表的形式,基于粗糙集理论进行适配性分析系统的知识提取,融合专家经验、末段飞行约束条件形成知识库。然后结合模型方法库,通过不确定性推理机制,建立了基于知识的景象适配性分析决策系统。

Knowledge-based Decision System for Scene Navigability Analysis

The deficiency of the method of selecting Scene Matching Area is considered.The unique features,stability features,expert knowledge,and constraint conditions of aircraft should all be considered when studying novel navigability method,The features and acquisition probability of reference map are integrated as decision table of navigability information system.A new method of navigability-knowledge acquisition based on rough set is proposed,The acquisitioned knowledge,expert knowledge and constraint conditions of mission planning are integrated as knowledge base,Uncertain reasoning mechanism is built up in the rule-based production system,Thus the knowledge-based decision system for scene navigability analysis is implemented.
