Credible Autonomy Safety Argumentation Paper

Here is our paper on pitfalls in safety argumentation for autonomous systems for SSS 2019.  My keynote talk will mostly be about perception stress testing but I'm of course happy to talk about this paper as well at the meeting.

Abstract   A significant challenge to deploying mission- and safety-critical autonomous systems is the difficulty of creating a credible assurance argument. This paper collects lessons learned from having observed both credible and faulty assurance argumentation attempts, with a primary emphasis on autonomous ground vehicle safety cases. Various common argumentation approaches are described, including conformance to a non-autonomy safety standard, proven in use, field testing, simulation, and formal verification. Of particular note are argumentation faults and anti-patterns that have shown up in numerous safety cases that we have encountered. These observations can help both designers and auditors detect common mistakes in safety argumentation for autonomous systems.
