Using the Unified Architecture Framework to Perform Hazard Analysis for Systems of Systems

Abstract

AbstractHazard analysis for individual systems is a task that is required as part of the production of most complex systems to identify hazards and to take appropriate measures to alleviate such hazards. It is a laborious and expensive task that requires key specialists and lengthy analysis. This is not just for systems on their own. Since collaboration between systems is becoming increasingly important, this complicates hazard analysis even further. It requires a systemic process looking at the individual systems as well as the system of systems and the environment in which they operate. The example looks at the concept of platooning i.e., where trucks transporting goods can operate as a platoon, traveling very closely together under the control of a platoon leader. Platooning has the benefit of reducing traffic and harmful emissions but introduces new hazards that must be examined and mitigated. The paper describes an approach to hazard analysis for a system of systems (SoS) that uses a model created using the Unified Architecture Framework (UAF) as an aid in identifying and analyzing hazards.
