Abstract

The smooth operation of passenger and freight networks requires regular
preventive maintenance where infrastructure segments are fully or partially
closed for a few days. These possession necessitate large changes in the
annual timetable. The re-scheduling takes place up to two months before
the operations.

In this research we present an iterative optimisation approach for the
adjustment problem of a periodic timetable. The algorithm consists of a
macroscopic network-level timetable optimisation model and mesoscopic
(station-level) platform track optimisation model. The models are connected
by a feed-back loop.

We illustrate the power of the optimisation approach by applying it to
realistic large-scale problem instances of Netherlands Railways. The
instances concern the entire Dutch railways network, and feature various
combinations of simultaneous maintenance possessions. Our methods are able
to provide practically relevant solutions within a few minutes of
computation time.
