THE SAFETY-CRITICAL SYSTEMS CLUB, Seminar:
New Safety Analysis TechniquesThursday 11 June, 2020 - London, UK
This seminar will look at emerging, novel and recently established techniques for analysing aspects of safety systems: their overall properties, their architecture and interactions, their software, hardware and their data.
Safety systems require analysis for potential failures that can lead to hazards. Traditional techniques tend to have limited applicability in today's world of highly complex, interconnected, continually updated systems. Learning systems bring new analysis problems as the faults may be contained in the training data rather than the system itself.
Techniques such as STAMP/STPA will be covered as well as emerging methods for analysing hazards in context (Environmental Hazard Analysis). The uses and abuses of Bow-Ties will be covered. The Functional Resonance Analysis Method (FRAM) will be considered. New techniques for analysing autonomous and machine learning systems will be discussed. The issues of analysing systems of systems will be covered. Tools and techniques for analysing service aspects (e.g. based on Swimlane Diagrams and Business Process Model and Notation, BPMN) and data safety will also be covered (e.g. use of data FMEA).
There will be a range of speakers covering different techniques. A wrap up session at the end of the day will discuss the most promising contenders.
