A Novel Approach to HW/SW Integration Testing of Route-Based Interlocking System Controllersesigns of realistic “real-world” complexity is possible and ready for industrial application. In this paper, we present a new model-based testing strategy for interlocking system controllers that exploits the fact that the design has already been verified, so that it can be used as a reference model

Operational Security – A Coming Evolution of Railway Operational Procedures Under the IT Security Thlly evolved into a centralize- and digital-controlled, information- and communication-based system. IT security was not considered during the system (re)design. This paper begins with discussing the need and absence of procedures to sustain operations when an IT security breach has occurred or is su

Correct Formalization of Requirement Specifications: A V-Model for Building Formal Modelsrds for safety critical systems recommend or even require the use of formal methods. However, building a formal model for a given specification is challenging. This is, because verification results must be considered with respect to the validity of the model..This leads to the question: “Did I build

Verification of Railway Interlocking - Compositional Approach with OCRAin order to allow a safe operation of the train traffic. Interlockings are controlled by a software logic that relies on a generic software and a set of application data particular to the station under control. The verification of the application data is time consuming and error prone as it is mostl
