Planning Knowledge

Domain knowledge representation is various and domain-concerned. The aircraft assembly process planning (A2P2) is a special domain, a lot of things should be taken into account, and the knowledge representation of A2P2 is complicated. It is focused on the knowledge representation of A2P2 in this paper. Based-on case, the framework of A2P2 knowledge is presented. The main considerations of A2P2 are analyzed, the transformation and reassembly of native A2P2 knowledge is studied, the features of A2P2 is acquired, and the formalizable framework of A2P2 is proposed. With BNF, a formal description of A2P2 knowledge is given.

Knowledge Ontology

In aviation industry, it’s urgent to build a scientific and effective knowledge system with high scalability to change the fact that the data is rich while the knowledge is deficient. We constructed the knowledge ontology of aircraft assembly with cyclic acquisition and seven step methods based on ontology thought. Then, we obtained the potential relationship related to process and abstract process ontology through logic reasoning. Finally, OWL is applied for ontology formal description to realize knowledge standardization and normalization. It’s meaningful to reuse, share the assembly process knowledge and further reasoning in the aviation field.
