Researches on the Multi-ontology based Safety Requirements Elicitation Method of Military Aircraft Systems Software

Nowadays, there are many researches on the ontology-based software requirements elicitation approach. However, there are still some disadvantages. One of the disadvantages is lacking of researches on military aircraft systems (MAS) ontology. Another is lacking of ontology-based software safety requirements elicitation approaches. This paper adopts ontology to construct the safety requirements knowledge multi-ontology framework (SRKMOF) of MAS. Moreover it introduces the software safety requirements error pattern (SSREP) which can be merged into the foregoing framework to enrich ontology knowledge. Furthermore the multi-ontology based safety requirements elicitation approach can be obtained. The SSREP can be weaved into the task ontology (TO) by aspect-oriented method (AOM). Finally, a case study is presented to validate the effectiveness of the proposed safety requirements elicitation approach. The results show that the number of safety requirements errors in safety requirements document obtained by the proposed approach is less than the comparative approach. It shows that the proposed approach is effective.
