Preliminary hazard analysis generation integrated with operational architecture-application to automobile

Abstract

We are witnessing evolution of standards (as the functional safety one) and increasing of complexity. This implies to perform safety studies efficiently and earlier in the context of Model-Based System Engineering. So, in this article, we will propose an evolution of the Preliminary Hazard Analysis (PHA) method in order to comply with the overall safety requirements in the automotive domain. To demonstrate its usefulness, we apply this method to an industrial case which concerns the hazard analysis of unintended acceleration of a vehicle.
