The company VINCI gave its award “Prix de l’Innovation VINCI 2015 pour la région Grand Ouest” (Innovation prize for the West Region of France) to the ExtendSim model called OSILI. The model studies the TGV line Tours-Bordeaux on design and operational issues, to see if high-speed trains meet reliability, availability and regularity criteria.
For example, the model simulates incidents on the line to appreciate their impact, calculate the entailed delays. Simulation provides precise results, close to reality. It makes it possible to replay incidents, and better evaluate the arbitration rules then selected.
The model should be extended in order to study other lines and new trains.
