Multi-objective disruption management for robust railway operations

Sponsor: Swiss Federal Railways (SBB)

Team: Michel Bierlaire (PI), Lea Ricard (PM)

Period: April 01, 2024-October 31, 2025

In passenger railway services, a timetable defines the scheduled arrival and departure times of trains at designated stations. When a disruption occurs, the railway operator must establish a disposition timetable, a complex task due to the intricacies of rail operations and the interactions in the network. This research aims to develop a decision-support tool that optimizes disruption management using a multi-objective optimization approach. The tool will account for system constraints while minimizing passenger inconvenience, operational costs, and deviations from the original timetable. Designed with practitioners' needs in mind, it will be integrated into the industrial software Viriato, enabling the use of real production data for algorithm evaluation and refinement.
