基于统一描述框架的导弹设计知识模型研究

Knowledge Model of Missile Design Based on Unified Description Framework

为了解决基于知识的导弹设计中异构知识难以共享、重用及有效支持推理的问题,提出了一种基于统一描述框架的本体化知识模型。首先研究了导弹设计中各类知识的表达形式,针对这些异构的知识提出了一种统一描述框架,而后研究了基于这种统一描述框架的本体化知识模型,在该模型中定义了知识基本建模单元,其可直接用于各类异构知识的表达和建模。最后利用导弹气动设计知识建模的应用示例说明了研究成果的有效性。

In order to solve the problem that the heterogeneous knowledge in missile design is difficult to share, reuse and support to reason, an ontology model of knowledge based on a unified description framework is proposed. Firstly, the formats of representation for all kinds of knowledge in missile design knowledge are studied, and then a unified description framework for this knowledge is proposed. Secondly, the ontology model of knowledge is studied. In this model, basic cell for modeling is defined, which could be used to modeling directly. Finally, an application example modeled by pneumatic knowledge in missile design verifies the validity of the modeling method.
