Digital Safety Cases, Digitaler Bahnbetrieb (Digital Railway Operation)

April 2019 – ongoing, Deutsche Bahn AG

As part of the “Digitaler Bahnbetrieb” project (DBB, or Digital Railway Operation), digital safety cases were also developed alongside the model-based functional description during regular operation. This looks at the malfunctioning of individual subsystems and their impact on adjacent systems.

SIGNON provides support here by

  • analysing applicable standards with regard to safety,
  • compiling hazards
  • undertaking design-related considerations regarding illustration/implementation
  • of hazards in the Capella model and
  • incorporating hazards into the Capella model.
