High-quality interface specifications with SysML modelling

March 2011 | Christian Fischer, Thomas Lauscher, Thorsten Hiebenthal

This article describes an approach that, starting with a coarse view of the system, leads to a detailed interface specification in clearly defined steps. The approach has been developed in the course of many technical discussions in collaboration with railway engineering experts of Deutsche Bahn AG. It is especially suitable for creating high-quality specifications in the complex environment of railway engineering. The procedure has become standard in the project NeuPro of DB Netz AG. Due to its clear structure, the approach is highly suitable for major projects with large teams of specifiers.
