Abstract
In this paper we address a real world optimisation
problem, the Rail Track Inspection Scheduling Problem (RTISP).
This problem consists of scheduling network inspection tasks.
The objective is to minimise total deadhead distance.
A mixed integer formulation of the problem
is presented. A column generation based algorithm is proposed
to solve this rich arc routing problem. Its performance
is analysed by benchmarking a real world dataset from the French national
railway company (SNCF). The efficiency of the algorithm is compared
to an enhanced greedy algorithm. Its ability to schedule one
year of inspection tasks on a sparse graph with thousand nodes, arcs
and edges is assessed.
