Verification and Validation of a new type of Railway Signal through MBSE and Simulation

Here are the slides from a presentation I gave at both the INCOSE UK conference (Nov-18) and the Dassault Systèmes User Conference (Dec-18). The approach was based around a model built using the Systems Modeling Language (SysML) and the No Magic Cameo System Modeler - No Magic are of course new members of the Dassault Systèmes family. 

The primary purpose of the system is for a replacement warning (distant) signal without the need for all the power and control cabling between the signal and the control centre. This is achieved by a wireless data-link and a self-contained power source. The technology employed by the power source is flexible but it is envisaged that this will mostly be batteries charged by a methanol fuel cell.

The model includes a full structural and behavioural description of the system and is capable of simulation. This allowed us to calculate some key measures-of-effectiveness (MoE) such as total power demand and maximum response time.

Full traceability was included between the structure, behaviour and the requirements and finally a product specification generated directly from the tool.
