Abstract
We address the problem of simultaneously scheduling trains and maintenance time slots on a railway networks. Both actions compete for the available infrastructure capacity, and have different economic interests: one to deliver service to customers, and revenues to the operator; the other to be able to deliver it also in the future; and to reduce costs. We study two perspectives of integrating preventive maintenance tasks in normal operations, in a tactical horizon when amount of maintenance is fixed, but its precise scheduling in time and space is not; while operations can be adjusted slightly from the plan, to make room for the maintenance tasks and related possessions.
One challenge is the integration of trains and maintenance scheduling with the same level of detail, which is achieved by considering virtual trains. This allows integrated operations scheduling, which delivers better results than the sequential approach currently used. A further challenge focuses more on the uncertainty of duration, minimizing the deviation of actual plans from the planned timetable, and also maximizing the number of aggregated maintenance works under stochastic disturbances. The tradeoff between the two conflicting objectives is resolved by computing the Pareto optimal solutions. Mehr anzeigen
