Use case description: Onboard Maintenance System (OMS) is one of the important systems in aircraft, it is responsible for fault diagnosis and prediction, as well as data collection and transmission. However, due to its complexity, modelling OMS is recognized as a tough task for avionics development in aircraft design. The KARMA (Kombination of ARchitecture Model specificAtion) language is proposed to support architecture design and process definition of OMS with a model-based systems engineering approach. KARMA is expected to support descriptions and simulations of different architectural views of systems engineering.

Use case goal: The aim of this use case is to use top-level ontology to support aircraft design and manufacturing, particularly on model-based systems engineering and domain-specific knowledge on fault detection.
