About XRCE

This meeting between public and private research organized by the CNRS groups in Operational Research and Mathematics and Optimsation and Applications on the topic of "l’Optimisation et la Programmation Mathématique en Contexte Industriel".

Sofia Zarouar Michel presenting  "Stochastic optimization of public transport schedules".

Full programme.

Held at the Institut Henri POINCARE (IHP) 12 Rue Pierre et Marie Curie, Paris, Thursday 12th November 2015.

Abstract: By analyzing the data provided by sensors, electronic transactions and mobile apps, Xerox helps city transportation agencies to understand how travelers are using public transit and to better respond to their ever changing needs. One of the major weaknesses of public transport, as perceived by travelers, is the time lost during transfers. In this talk, I will present a new data driven approach to minimizing transfer waiting times. We model the problem as a two stage stochastic program that explicitly takes into account the inherent variability of a real world public transportation system. Preliminary results with the data of the city of Nancy show a significant reduction of the expected transfer waiting times.
