Abstract

The increasing complexity of automatic train supervision and regulation systems (ATS/ATR) has placed more and more importance on the use of modeling to describe and understand system behaviour. Such a model should provide a de- scription suitable for requirement review and approval by the rail operator as well as detailed views for use by designers, implementers and testers. The Uni- fied Modeling Language (UML) is a visual modeling standard that has been adopted by Alcatel to capture ATS/ATR models. The choice of a standard nota- tion was motivated by our need to exchange models with various stakeholders; the selection of UML in particular was influenced by its wide adoption in the software industry. We have gained our experience with using the Unified Modeling Language during the development of our latest generation product for train regulation and supervis
