Model-Based Mission Assurance/Model-Based Reliability, Availability, Maintainability, and Safety (RAMS)

Among all the disciplinary analyses performed during the development of a new aircraft, reliability and safety play the most important role for the certification and operation of the aircraft. Traditionally, reliability and safety analyses are document-based, i.e., a vast quantity of tables and reports collect all the assumptions, inputs, decisions, and results. However, this approach entails several disadvantages hampering the quality and the effectiveness of the analyses, especially with the introduction of novel technologies that make the aircraft a system with ever-increasing complexity. Therefore, the research community proposes innovative model-based approaches to support the development of a new aircraft. This chapter specifically focuses on the model-based approaches proposed in literature dealing with reliability and safety analyses.
