Ir. Rob Richelle has been nomitated by the faculty of Civil Engineering and Geosciences for the prize of 'Best Graduate' of TU Delft. During his dual master thesis, Rob investigated the mechanisms to disconnect a rail system in subsystems to make it robust against disturbances (MSc TIL parts) and developed a methodology to evaluate the robustness of complex stations (MSc CE / TP).
Robustness by system untangling in large complex stations
At large complex stations multiple railway lines come together, which automatically generates traffic and passenger flows in multiple directions. Mixing these flows, results in interdependencies between lines which in case of an incident can lead to a complete disruption or even suspension of train services in all directions. A solution applied in Utrecht station is system untangling, which has been defined as the ‘creation of multiple parts within the railway system that have less interaction with each other and therefore prevent irregularities from spreading and increase the system’s robustness’.
But through which infrastructure subsystems are all these flows connected in the ‘spaghetti mix of lines’ at complex stations? And how should they be untangled in order to be effective? My research had the objective to gain insight in this untangling strategy, to provide an overview of untangling possibilities and model their potential to decrease the spread of irregularities.
During the 'Best of TU Delft' event, taking place at 22nd November 2017, the nominated candidates from all the faculties will pitch their ideas and the overall 'Best Graduate' of TU Delft will be determined by a jury. If you would like to attent, you are very welcome at the TU Delft Auditorium, the ceremony will start at 15:30.
