Abstract
Nowadays, systems such as motor vehicles, medical devices, or industrial machines are designed according to functional safety requirements. The main criterion is the safety integrity level (SIL), which is mainly based on failure probabilities. A development approach based on models, also called Model-Based Systems Engineering (MBSE), is increasingly coming into focus for a highly regulated development process. Probabilistic safety and reliability analyses for calculating failure probabilities and applying these in MBSE are currently only integrated to a limited extent. Merging partial development processes increases confidence and couples the design process with all stakeholders. This paper presents a general method that develops domain-specific extensions based on specifications from Object Management Group (OMG) regarding risk analysis and assessment modeling for more practical applicability of MBSE for functional safety.
