Preliminary Hazard Analysis Generation integrated with Operational Architecture – Application to Automobile

Abstract. We are witnessing evolution of standards (as the functional safety one) and increas-ing 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 Pre-liminary Hazard Analysis (PHA) method in order to comply with the overall safety require-ments 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
