About this talk

Abstract: Current functional safety standards tend to focus on single individuals (e.g., vehicles, machines). A project named Model Based Risk Assessment Safety Analysis (MBRASA) was initiated to study hazard analysis for system of systems. This presentation will discuss 1) how hazard analysis can be performed based on UAF models of specific system of system concepts, 2) how an extended hazard and risk analysis methodology can be facilitated by using the extrapolated system definition model and 3) how safety cases for models of the early phases can be used to facilitate swifter progress in getting systems ready for certification. Two model examples will also be described: 1) logistics facility and 2) truck platooning. Bio: Lars-Olof Kihlström is a principal consultant at the Swedish consultancy company Syntell AB. He has a degree in Physics Engineering from the Royal Institute of Technology in Stockholm. He has been working with Model based system design and engineering for more than 40 years using a variety of tools. Since 2005 his engineering work has largely dealt with architecture models and architecture frameworks. He was a member of the team responsible for the NATO architecture framework version 3 and 3.1, has in depth knowledge of MODAF DoDAF 2 and NAF version 4 and has been a member of the UPDM/UAF group since the work for the OMG standard of the framework started.
