Abstract

A scheduling system and method for moving plural objects through a system described as a freight railway scheduling system. The scheduling system utilizes a cost reactive resource scheduler to minimize resource exception while at the same time minimizing the global costs associated with the solution. The achievable movement plan can be used to assist in the control of, or to automatically control, the movement of trains through the system. The actual location where an activity is to be performed is automatically selected as a function of one or more specified criteria.

Claims

1. In a railway scheduling system in which each resource used in each scheduled activity has an incremental cost associated with it, and in which the location at which local activities are to be performed must be selected in the scheduling process, the automatic selection of a location by the movement planner for specifically identified trains to which local movement activities have been scheduled.

2. The system of claim 1 wherein the selection criteria is one of more of (a) the specific train, (b) the type of train and (c) the direction from which the train approaches the location.

3. The system of claim 1 wherein the selection criteria includes the suitability of the location for the type of activity to be provided.

4. The system of claim 3 wherein the type of activity is the setout or pickup for railway cars.

5. The system of claim 3 wherein the type of activity relates to the train locomotive and to one or more of engine work, power change and fueling.

6. In a railroad system in which plural trains are moved along a network of railway tracks under control of a dispatcher assisted by a scheduling computer prepared movement plan that assigns resources to activities and considers the cost of each activity and assigned resources in scheduling the movement of trains over the tracks, a method of automatically selecting a location for the performance of local activity within a geographic area for an identified train comprising the steps of:

(a) establishing an activity profile for each of the available locations within the geographic area;

(b) establishing criteria for the selection of a location;

(c) establishing a movement plan for an identified train requiring a local activity using the established criteria to automatically select a location at which the activity is to be performed.

7. The method of claim 6 wherein the criteria is one or more of (a) the type of activity, (b) the type of train, (c) the specific train, (d) the direction of travel to and/or from the location, (e) the route to and/or from the location, and (f) the use of track by both currently planned and forecast trains.

8. The method of claim 7 wherein the criteria as to (a) the type of activity, (b) the type of train, (c) the specific train, and (d) the direction of travel to and/or from the location includes statistical information.
