Abstract

An airline operations control system for an airline having multiple aircraft and multiple routes formed by one or more flights where the airline operations control system includes a computer searchable database a query module configured to query the database and a display module and a method of controlling operation of the airline having the multiple aircraft and the multiple routes.

Claims

1. An airline operations control system for an airline having multiple aircraft and multiple routes formed by one or more flights, which are implemented by the aircraft flying the flights forming the routes, the system comprising:

a computer searchable database comprising;

aircraft inventory data including a unique identifier for each of the multiple aircraft;

aircraft status data, including a maintenance schedule, for each of the multiple aircraft in the aircraft inventory data;

route data including each flight on a route, a destination for each flight, and the aircraft designated to fly each flight; and

maintenance resources including maintenance resources for each of the destinations;

a query module configured to query the database for and output stable operating solutions that ensure completion of the multiple routes based on at least one failure of at least one aircraft flying one of the routes, wherein the query module is executed on a computer configured to access the database; and

a display module configured to display at least a subset of the stable solutions to an aircraft operations personnel for use in determining a response to the failure.

2. The airline operations control system of claim 1 wherein the query module determines the stable solutions by permutating over the database an airline operation algorithm that simulates the execution of each of the multiple routes to completion and varying for each permutation at least one of a group of inputs:

repairing the failure now, delaying the repair, delaying the flight, canceling the flight, and swapping the aircraft with the failure for another aircraft.

3. The airline operations control system of claim 2 wherein the database further comprises prognostic aircraft health data and the airline operation algorithm incorporates prognostic failures in other aircraft.

4. The airline operations control system of claim 3 wherein the query module ranks the stable solutions based on at least one of airline personnel preference and cost.

5. The airline operations control system of claim 4 wherein the query module outputs a subset of the stable solutions based on the ranking.

6. The airline operations control system of claim 1 wherein the aircraft status data comprises at least one of:

fully healthy, grounded, time-limited dispatch, and limited dispatch.

7. A method of controlling operation of an airline having multiple aircraft and multiple routes, the method comprising:

providing a computer searchable database comprising;

aircraft inventory data including a unique identifier for each of the multiple aircraft;

aircraft status data, including a maintenance schedule, for each of the multiple aircraft in the aircraft inventory data;

route data including each flight on a route, a destination for each flight, and the aircraft designated to fly each flight; and

maintenance resources including maintenance resources for each of the destinations;

determining a failure in one of the aircraft designated for a flight;

determining stable solutions of operation of the airline by permutating over the database an airline operation algorithm that simulates execution of each of the multiple routes to completion and varying for each permutation at least one of a group of inputs;

repairing the failure now, delaying the repair, delaying the flight, canceling the flight, and swapping the aircraft with the failure for another aircraft; and

displaying at least a subset of the stable solutions to an aircraft operations personnel for use in determining a response to the failure.

8. The method of claim 7 wherein the database further comprises prognostic aircraft health data and the airline operation algorithm incorporates prognostic failures in the other aircraft.

9. The method of claim 8 further comprising requesting a ranking input from the aircraft operations personnel.

10. The method of claim 9 wherein the ranking input comprises at least one of a preferred ranking and a best ranking.

11. The method of claim 9 further comprising requesting a selection input from the aircraft operations personnel regarding which of the solutions was selected for implementation.

12. The method of claim 11 wherein the displaying at least a subset of the stable solutions comprises selecting the subset based on ranking and selection.

13. The method of claim 7 wherein the aircraft status data comprises at least one of:

fully healthy, grounded, time-limited dispatch, and limited dispatch.

14. The method of claim 13 wherein when the aircraft status data comprises grounded, delaying the repair is removed as a variable input to the airline operation algorithm.

15. The method of claim 13 wherein when the aircraft status data comprises time-limited dispatch, delaying the repair is maintained as a variable input to the airline operation algorithm until the time limit is met.

16. The method of claim 7 wherein the maintenance resources further comprise traveling maintenance resources.

17. The method of claim 7 wherein the subset of displayed solutions is selected based on at least one of the following constraints:

cost, no canceled flights, reliability, customer satisfaction, and that all passengers reach their destinations on the day planned.

18. The method of claim 17 wherein the no canceled flight constraint and all passengers reaching their destination on the day planned constraint are limited to one of a holiday and the day before the holiday.

19. The method of claim 17 wherein customer satisfaction is determined based on at least one of fewest cancelled flights, fewest passengers not arriving at their final destination on the day planned, fewest passengers delayed more than 15 minutes, total flight delays, total passenger delays, and post-flight customer satisfaction surveys.

20. The method of claim 17 wherein the cost is determined based on at least one of a predetermined value for cost per minute of delay, cost per cancellation, cost per minute that an aircraft is out of service, cost per swap.

21. The method of claim 7 wherein the determining a failure comprises at least one of an actual failure or an artificial failure.

22. The method of claim 21 wherein the database further comprises prognostic aircraft health data and the artificial failure is provided from the prognostic health data.
