  • formal model based assurance cases in isabelle sacm an autonomous underwater vehicle case study
    Formal Methods, 2020
    Co-Authors: Simon Foster, Yakoub Nemouchi, Colin Ohalloran, Karen Stephenson, Nick Tudor
    Abstract:

    Isabelle/SACM is a tool for automated construction of model-based assurance cases with integrated formal methods, based on the Isabelle proof assistant. Assurance cases show how a system is safe to operate, through a human comprehensible argument demonstrating that the requirements are satisfied, using evidence of various provenances. They are usually required for certification of critical systems, often with evidence that originates from formal methods. Automating assurance cases increases rigour, and helps with maintenance and evolution. In this paper we apply Isabelle/SACM to a fragment of the assurance case for an autonomous underwater vehicle demonstrator. We encode the metric unit system (SI) in Isabelle, to allow modelling requirements and state spaces using physical units. We develop a behavioural model in the graphical RoboChart state Machine Language, embed the artifacts into Isabelle/SACM, and use it to demonstrate satisfaction of the requirements.
