Pattern-based Requirements Model Using SysML for a Helicopter’s Pilot Assistance System

Kurzfassung

Development of a pilot assistance system involves many disciplines. Requirements analysis and traceability becomes difficult while developing software for such multidisciplinary systems. The modeling with SysML facilitates better design of software along with non-software components. The pattern based requirement analysis using problem frames encourages knowledge reuse and provides better understanding of domain and requirements. Since PFs do not have standard notations and linguistic support, their use in industry is restricted. In this paper, we introduce a systematic model and pattern based software development method which combines SysML and problem frames in order to cope with the development complexity of a helicopter pilot assistance system. It also provides SysML based standard notations for Problem Frames. The advantage of the proposed method is that all the artifacts modeled during the software development are linked together. A smooth and synchronized transition from requirements elicitation to software design, implementation, testing and maintenance is achieved.
