摘要

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 these two extremes. Even so, a key issue for system designers is whether to allow the computers to control the traffic directly without reference to the line controllers, or whether they should only operate in the decision support role. Again, practical experience is leading towards systems incorporating both concepts and using one or the other depending on the severity of the disruption.
