In this paper, we describe a concept for the automatic allocation of general Safety Integrity Levels (SILs) to subsystems and components of complex hierarchical networked architectures that deliver sets of safety critical functions. The concept is generic and can be adapted to facilitate the safety engineering approach defined in several standards that(More)
For systems where functions are distributed but share support for computation, communication, environment sensing and actuation, it is essential to understand how such functions can affect each other. Preliminary Hazard Analysis (PHA) is the task through which safety requirements are established. This is usually a document-based process where each system(More)
