The Australian System Safety Conference (ASSC) is organised by the Australian Safety Critical Systems Association (aSCSa), a National Special Interest Group of the Australian Computer Society. The aSCSa promotes co-operation among academic, industrial, commercial and governmental communities surrounding the practice and advancement in the production and operation of safety-related systems in Australia.
ASSC 2017 celebrates the 25th anniversary of the founding of the first workshop/conference organised by the aSCSa. In these 25 years, the association has moved beyond the original focus to broader concerns of system safety, safety management and now security vulnerability.
The theme of ASSC 2017 is around the evolving understanding and tools of the safety sciences – identifying and addressing the modern challenges of system safety in design, for today’s and tomorrow’s complex safety critical systems. Challenges also include how to build, rate and sustain the standards of competence and knowledge of safety engineers and managers.
SYSTRA Scott Lister is proud to be a sponsor of ASSC 2017. With strong capabilities and an innovative nature, SYSTRA Scott Lister is posing evolutionary and disruptive challenges to the safe design of intelligent and autonomous systems by incorporating disparate concepts of Goal Structure Notation (GSN), Systems of Systems and WHS/SFAIRP to identify and treat the risk associated with the operation of safety-critical systems.
SYSTRA Scott Lister’s consultants – Vamsi Madasu & Kevin Anderson – will present some of the innovative concepts in the following presentation at ASSC 2017:
Deriving risk based Target Levels of Safety for Autonomous Systems
Vamsi K. Madasu & Kevin J. Anderson
10:30 – 11:30 on Thursday, 1st June 2017
A pragmatic and defensible set of risk-based Target Levels of Safety (TLOS) are defined for determining whether the level of risk is reasonably acceptable when evaluating the safety of mission critical systems. Although TLOS have been developed over the past 50 years by numerous stakeholders in different critical sectors (Hazardous chemicals, Rail, Aviation, Defence, Nuclear, Space, etc.), there is no consensus yet on risk-based TLOS for Autonomous Vehicle Systems.
In this presentation, Vamsi & Kevin will propose TLOS for both ground (driverless trains and cars) and air (Unmanned Aircraft) based autonomous vehicle systems. The presentation will initially provide a chronological review of the development of the various risk metrics and frameworks (such as ALARP, SFAIRP) across different industry sectors. And by then considering the unique nature of the Autonomous Systems (especially, those operating commercially) and socially accepted risk, a set of risk-based TLOS, defined for both Individual and Collective risk, will be presented. Finally, the presentation will end with a discussion on the prevalent aviation and ground transport safety regulations.
