Abstract

Solving timetable disturbances is a daily task of operational railway control. The timetable recovery usually represents a significantly more complex task of designing the initial timetable, which is done at the level of tactical planning. The reasons for this are the following: this task requires a high degree of urgency; there is no universal optimization criterion applicable to all the situations; some necessary information may be unavailable; it is mostly about a large size combinatorial optimization problem. In this paper, the problem of the operational reconstruction of timetable is modeled as a job shop scheduling problem and solved by the available constraint programming software tool. The solutions obtained by the implemented software are compared with the solutions of experienced dispatchers. Experiments have confirmed the ability of the model and software to support the operational railway control.
