Stepwise Development and Model Checking of a Distributed Interlocking System - Using RAISE
- 892 Downloads
This paper considers the challenge of designing and verifying control protocols for geographically distributed railway interlocking systems. It describes for a real-world case study how this can be tackled by stepwise development and model checking of state transition models in an extension of the RAISE Specification Language (RSL). This method also allows different variants of the control protocols to be explored.

The authors would like to express their gratitude to Jan Peleska from whom the case study originates and together with whom the second author had the great pleasure to verify the same case study by theorem proving . We would also like to thank him and the reviewers for very useful comments to drafts of this paper.
