航迹规划领域本体的构建与应用

飞行器航迹规划方法种类繁多且涉及的领域知识庞杂,快速掌握各规划方法的特点并从中选取合适的方法进行规划十分困难，其原因在于缺乏航迹规划相关领域知识的表示和重用。为了实现方法重用，提高规划效率，采用本体技术描述航迹规划领域中的常用概念、概念的层次结构及概念间的关系，建立了航迹规划领域本体。它不仅能够对航迹规划领域知识进行规范描述，实现从规划问题概念建模到规划模型软件实现的自然过渡，还可以完成规划算法类型的自动推理，帮助规划人员快速分析比较各类算法，建立规划模型，从而实现领域知识重用。

Research and application of an ontology for aircraft route planning

The amount of methods used in route planning (RP) for aircrafts has greatly increased during the last few years. It is difficult to master these methods and make a fast choice to use among them, which results from the lack of domain knowledge representation and reuse for RP. To achieve the domain knowledge reuse and efficient planning process, ontology is adopted to describe the concepts and the relationship between them. An ontology defined by web ontology language (OWL) for RP dubbed ONTRP is developed to specify the domain knowledge and fill the gap between conceptual model for RP and software implementation of RP. Moreover, ONTRP can help people make an analysis and comparison between two RP algorithms by means of automatic reasoning and establish the models for RP efficiently.
