Research on a Knowledge Model of Aircraft Design Based on Unified Description Framework

In order to solve the problem that the heterogeneous knowledge in aircraft design is difficult to share, reuse and support to reason each other, a ontology model of knowledge, based on the unified description framework, was proposed. Firstly, the formats of representation for all kinds of knowledge in aircraft design knowledge were studied, and then a unified description framework for this knowledge was proposed. Secondly, the ontology model of knowledge was studied. In this model, basic cell for modeling was defined, which could be used to modeling directly. At last, an example, modeling of pneumatic knowledge in aircraft design verified the validity of the modeling method in this paper.
