- W788461199 abstract "This paper reviewed the general concepts and procedures being applied to the control of train services following disruption. Systems vary from simply encapsulating known rules for recovery to using full scale simulation and optimization embedded in an on-line real-time controller. The computer-generated control inputs can be applied directly to the railway or used to advise the human line controllers. Systems employing stored algorithms are already in operation, often taking direct control from small disturbances but handing back to the line controllers when the disturbances exceed a set level. Railways require enormous investment in infrastructure and it is therefore imperative that means are sought to maximize the utilization of that infrastructure. This paper reviews some of the applications of computers to the particular problem of recovering from traffic disturbances in way that seek to minimize the consequent loss of capacity. To some extent, the processes of re-scheduling 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 modeling and rigorous mathematical optimization procedures. In practice, such systems already exist, and those under research and development, are generally something of a comprise 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." @default.
