Abstract

Railways require enormous investment in infrastructure and it is therefore imperative that means are sought to maximise the utilisation of that infrastructure. This paper reviews some of the applications of computers to the particular problem of recovering from traffic disturbances in ways which seek to minimise the consequent loss of capacity. To some extent, the processes of rescheduling after disruption are similar to scheduling in the first place, and thus some reference will be made to methods being used for automatic time-tabling. The management of recovery can vary between entirely manual and entirely automatic, with full predictive modelling and rigorous mathematical optimisation procedures. In practice, such systems as already exist, and those under research and development, are generally something of a compromise between
