  • a processor for receiving orders for rail service, each of the orders including an identification of a time interval over which the service is to be provided and a cost function;

    a processor for receiving user-defined constraints;

    a processor for receiving data as to an availability and capability of resources including train action effects and associated costs;

    a processor for selecting resources to perform each activity in the orders;

    a processor for accessing an activity list for the selected resources for each of the orders;

    a processor for converting the activity lists into time intervals;

    a processor for grouping the time intervals for the orders; and
