UML, on the other hand, encourages large models to be expressed in a single, detailed level and relies on simulation and model testing techniques for verification. The advantage of proof over model-testing is that the proof is valid for all instantiations of the model whereas a simulation must choose a typical instantiation. In the INESS project we take an extant UML model of a railway interlocking system and explore methodical ways to translate it into UML-B in such a way as to facilitate proof that the model satisfies certain safety properties which are expressed as invariants. We describe the translation attempted so far and insights that we have gained from attempting to prove a safety property. We propose some possible improvements to the translation which we believe will make the proof easier. date: 2011 date_type: published publication: Lecture Notes in Computer Science volume: 6957 publisher: Springer pagerange: 251 event_title: Formal Methods for Components and Objects event_location: Graz event_dates: 29 Nov 2010 event_type: conference refereed: TRUE official_url: http://eprints.soton.ac.uk/272921/ citation: Snook, Colin and Savicks, Vitaly and Butler, Michael (2011) Verification of UML models by translation to UML-B.
