Hazards in advising autonomy: Developing requirements for a hazard modelling methodology incorporating system dynamics

Hazards in advising autonomy: incorporating hazard modelling with system dynamics into the aerospace safety assessment process for UAS

“…A proposal for a closed-loop safety assessment process, incorporating HAZOP styled upon STPA, system dynamics modelling, and Bayesian inference, is proposed as an approach to extend the PASA for a UAS/UAV; as shown in Figure 9. This arises from an earlier provisional requirements analysis and a discussion of bottom-up model building [5,6]. To date, a dynamical model incorporating representative behaviours has been created, with a selection of hazardous vignettes also identified and explored.…”
