Abstract:
The needs to accelerate development of next generation train control technology, while meeting the quality standards and safety requirements demanded for the development of today’s distributed, software dominated, train transportation applications, can only be achieved through a novel methodology that addresses analysis and integration validation of sub-systems, via simulation-based virtual prototyping.
The methodology must be able to address, much earlier in the development cycle, design goals (among others) such as:
• Specifications Validation and Quality of Service Analysis,
• Systems safety evaluation and commissioning of automated train control systems,
• Early Integration Validation,
• Fast assessment of derivative designs,
• Compliance with transportation standards (EN50128 - SIL2).
Such methods actually used in some current projects can be seen as exemplary; they are paving the way for other transportation industry domains to adopt in confidence new system design paradigm shifts.
