Towards Verification of Constituent Systems through Automated Proof [article]

Luis Diogo Couto, Simon Foster, Richard Payne
2014 arXiv   pre-print
To support verification of these obligations we have developed a proof obligation generator and theorem prover plugin for Symphony.  ...  Our hope is that the resulting proofs can then be used to formally verify the conformance of each constituent system, which is turn would result in a dependable SoS.  ...  ACKNOWLEDGEMENTS This work is supported by EU Framework 7 Integrated Project "Comprehensive Modelling for Advanced Systems of Systems" (COMPASS, Grant Agreement 287829).  ...

Pass-Fail Criteria for Scenario-Based Testing of Automated Driving Systems [article]

Robert Myers, Zeyn Saigol
2020 arXiv   pre-print
The MUSICC project has created a proof-of-concept scenario database to be used as part of a type approval process for the verification of automated driving systems (ADS).  ...  This process must include a highly automated means of evaluating test results, as manual review at the scale required is impractical.  ...  Using Hb avoids this problem, as a vehicle is assumed safe in the absence of evidence to the contrary. However, failing to prove that a vehicle is unsafe is not the same as proving that it is safe.  ...

Synthesising Correct Concurrent Runtime Monitors [chapter]

Adrian Francalanza, Aldrin Seychell
2013 Lecture Notes in Computer Science  
This paper studies the correctness of automated synthesis for concurrent monitors.  ...  Finally, we devise a sound technique that allows us to prove monitor correctness in stages; this technique is used to prove the correctness of our automated monitor synthesis.  ...  A system A 1 exhibiting just the external behaviour A 1 αβ ⇒ satisfies ϕ safe , as would a system A 2 with just the infinite behaviour A 2 α ⇒ A 2 .  ...

A Taxonomy to Unify Fault Tolerance Regimes for Automotive Systems: Defining Fail-Operational, Fail-Degraded, and Fail-Safe [article]

Torben Stolte, Stefan Ackermann, Robert Graubohm, Inga Jatzkowski, Björn Klamann, Hermann Winner, Markus Maurer
2021 arXiv   pre-print
In addition to fail-operational, fail-degraded, and fail-safe, the core terminology consists of operational and fail-unsafe.  ...  This paper presents a taxonomy that allows defining the fault tolerance regimes fail-operational, fail-degraded, and fail-safe in the context of automotive systems.  ...  The definition of the fail-safe property of an automated driving Kopetz [53] describes the use of fail-safe and fail-operational system in the technical report ISO/TR 4804 [31] specifies the  ...

Safety-relevant mode confusions—modelling and reducing them

Jan Bredereke, Axel Lankenau
2005 Reliability Engineering & System Safety  
A mode confusion occurs when the observed behaviour of a technical system is out of sync with the user's mental model of its behaviour. But the notion is described only informally in the literature.  ...  Our approach supports the automated detection of remaining mode confusion problems. We apply our approach practically to a wheelchair robot.  ...  When all else fails, standardize.  ...

The Boyer-Moore Waterfall Model Revisited [article]

Petros Papapanagiotou, Jacques Fleuriot
2018 arXiv   pre-print
In this paper, we investigate the potential of the Boyer-Moore waterfall model for the automation of inductive proofs within a modern proof assistant.  ...  Various features, such as proof feedback and heuristics dealing with non-termination, that are needed to make this automated tool useful within our interactive setting are also discussed.  ...  This is a tricky issue for such automated systems because the user is in no position of knowing if progress is being made towards the proof or if the system will never terminate.  ...
