Abstract

A system and method of scheduling the movement of trains as a function of the predicted crew behavior and predicted rail conditions based on the historical behavior of the crew for specific rail conditions.

Claims

1. A method of scheduling the movement of plural trains over a rail network, each train having an assigned crew to operate the train comprising the steps of:

(a) maintaining a database of information related to the past performance of the movement of a first train as a function of the crew assigned to operate the first train, including crew model coefficients determined by historical parameters;

(b) mapping the past performance of the movement of the first train to each individual member of the crew by creating an association between the movement of the first train and the crew responsible for moving the train;

(c) mapping the past performance of the movement of the first train to a rail condition that existed at the time of the train movement by creating an association between the movement of the first train and the rail condition that existed at the time of the train movement;

(d) storing the mapped past performance for the individual member of the crew and the rail conditions;

(e) predicting the future performance of an individual member of a crew for a specified rail condition as a function of the stored information;

(f) scheduling the movement of a second train as a function of the predicted future performance.

2. The method of claim 1, wherein the step of maintaining a database of information related to the past performance of the movement of a first train includes comparing the actual movement of the first train with the movement plan of the first train.

3. The method of claim 1 wherein the step of scheduling the movement includes:

(i) assigning a second crew to operate the second train;

(ii) predicting a behavior of the second crew as a function of the information maintained in the database;

(iii) predicting the performance of the movement of the second train as a function of the predicted behavior of the crew;

(iv) scheduling the second train as a function of the predicted performance.

4. The method of claim 1 further comprising the steps of predicting the performance of an assigned crew for a specific rail condition as a function of the stored data.

5. The method of claim 4 wherein the predicted performance includes an estimated variance of time of arrival.

6. The method of claim 1 wherein the performance includes an estimation of the time required by a specific crew to travel a specific distance.

7. The method of claim 1 wherein the performance includes a measure of crew sensitivities to specific weather conditions.

8. A system for scheduling the movement of plural trains over a rail network, each train having an assigned crew to operate the train comprising the steps of:

a database of information related to the past performance of the movement of a first train as a function of the crew assigned to operate the first train including crew model coefficients determined by historical parameters;

a computer program for the movement of trains, the computer program comprising;

a computer usable medium having computer readable program code modules embodied in said medium for scheduling trains;

a computer readable first program code module for mapping the past performance of the movement of the first train to each individual member of the crew by creating an association between the movement of the first train and the crew responsible for moving the train;

a computer readable second program code module for mapping the past performance of the movement of the first train to a rail condition that existed at the time of the train movement by creating an association between the movement of the first train and the rail condition that existed at the time of the train movement;

a computer readable third program code module for storing the mapped past performance for the individual member of the crew and the rail conditions;

a computer readable fourth program code module for predicting the future performance of an individual member of a crew for a specified rail condition as a function of the stored information; and

a computer readable fifth program code module for scheduling the movement of a second train as a function of the predicted future performance.
