Abstract:
We consider optimal scheduling of track maintenance activities for a
railway network divided into sections. The goal is to find an optimal
time schedule for the maintenance activities and optimal routes for
the maintenance crew (including all necessary equipment and
technicians) that minimize the total setup costs and the travel costs
over the whole planning horizon. The maintenance time budget, which
can be the same, different, or flexible for each period, and the
minimum time to maintain a section are also taken into account. We
recast the track maintenance scheduling problem with three different
settings as three variants of the Capacitated Arc Routing Problem with
Fixed cost (CARPF), which are solved by transforming them into three
node routing problems. The proposed approach is demonstrated using a
case study of a part of the Dutch regional network.
