Abstract
This paper introduces a model-based computer-aided
methodology for safety analyses in development and as-
sessment processes for signalling and train control systems.
The objective is to realise the application of model-based for-
mal methods and simultaneously to reduce the outlay for us-
ing them to a degree acceptable in industrial practice. Instead
of performing safety analyses in parallel with the develop-
ment process, existing system analyses and design models are
used for deriving the necessary safety analyses models as au-
tomatically as possible. Therefore, statements on safety and
correctness can already be calculated in early development
phases with precise results. Those early statements are deci-
sive, because they make it possible to adapt and correct the
system design at an early stage and to do it cost-efficiently.
