一种基于本体的HLA SOM构建方法

Ontology Based Modeling Approach for HLA SOMs

HLA(High LevelArchitecture,高层体系结构)是大规模协同仿真领域最流行的标准和规范,而大规模协同仿真往往涉及多个相对独立的子系统(成员),其互理解问题始终是制约HLA应用的核心问题之一。提出了一种针对HLA SOM建模的类FCA(Formal Concept Analysis,形式概念分析)方法。该方法采用基于抽象本体的建模机制,类FCA的建模过程和基于扩展UML顺序图的建模方法。抽象本体根据应用上下文能够形成针对不同应用场景的应用本体,进一步提高了知识的重用度;本体模版存储了通用的协同本体一般架构和公理知识,有效提高了协同建模的效率;而扩展的UML顺序图能够对HLA系统的协同概念进行有效组织和建模。经过实例验证,该方法能够以一种用户友好的、有效、一致的方法支持跨学科的协同。

HLA （High Level Architecture） is a well-known standard of large-scale collaborative simulation. Since several independent sub-systems involved, lack of efficient mutual understanding （Collaboration Knowledge） organization and representation method for this kind of simulation limited its usage in industrial applications. A novel FCA-like federate collaboration ontology modeling method was proposed. This method adopted abstract ontology as modeling mechanism, FCA-like modeling process, and augmented UML sequence diagram-based modeling approach. In the proposed approach, by cloning itself to different application ontologies according to application context, abstract ontology has greatly improved reuse of collaboration knowledge. By organizing general collaboration schema and axiom knowledge, ontology template could accelerate preparations for HLA-based collaborations. And the augmented UML sequence diagram helps to organize the collaboration knowledge. An industrial case demonstrates that the proposed method can support multi-disciplinary collaborations in a human-friendly, efficient and consistent way.
