Martin Törngren is a Professor in Embedded Control Systems at the Mechatronics division of the KTH Department of Machine Design since 2002. He has particular interest in Cyber-Physical Systems, architectural design, system safety, model based engineering, and co-design of control applications and embedded systems. He has authored/co-authored more than 150 peer reviewed publications, and also been in charge of developing and leading both graduate and continued education courses, as well as the development of new/renewed master programs.

Networking and multidisciplinary research have been characteristic throughout his career. From 1999-2004 he served as the Chairman of the Swedish real-time systems association, and he has represented KTH as a core partner in the EU networks of excellence in Embedded systems design, Artist2 and ArtistDesign, and in the Artemis industrial association. He is moreover the principal initiator and Director of the Innovative Centre for Embedded Systems (www.ices.kth.se), launched in 2008.

Abstract. What will safety cases, and more generally, assurance cases, be like in a forthcoming era of Cyber-Physical Systems (CPS) - featuring unprecedented capabilities and complexity? Safety cases are commonly used today as an approach to provide structured arguments with accompanying evidence, to provide a compelling case that a system is safe for a given application in a given operating environment. In reflecting on trends and the evolution of CPS towards an ”open, live, smart, highly automated and collaborative paradigm”, I will discuss challenges, including limitations with current methodologies, and what I believe to be necessary directions for safety engineering and assurance cases. These directions include new takes on assurance and system development methodology, complexity management, safety barriers and operational risk management, and societal measures, all in the context of the envisioned future CPS paradigm.
