Abstract

Method and apparatus for calculating probabilities of service interruptions based on fault event indications. Instances of fault event indications are filtered to remove duplicate indications for the same fault event. Then a probability of the fault event indication causing a service interruption is calculated by dividing a number of service interruptions caused by instances of the fault event indication by the number of fault event indications. In the event that a particular fault event indication is associated with a high probability of causing a service interruption, a message can be automatically generated and transmitted upon receipt of a future instance of the service interruption. The message can provide information related to short-term solutions to address the fault event, long-term solutions to address the fault event, and parts and tools for addressing the fault event.

5. The computer-implemented method of claim 1, wherein the vehicle is an aircraft.

6. The computer-implemented method of claim 1, wherein the vehicle is a fleet of similar vehicles, wherein the total number of instances of the fault event indication for the vehicle includes a total number of instances of the fault event for the fleet of vehicles, and wherein the total number of instances of service interruptions for the fault event for the vehicle includes the total number of service interruptions for the fault event for the fleet of vehicles.

7. The computer-implemented method of claim 1, wherein the calculated probability of a service interruption for the fault event is proportional to the total number of instances of the fault event for the vehicle divided by the total number of instances of service interruptions for the fault event for the vehicle.

8. A system, comprising:

a computer processor; and

a computer memory containing a program that, when executed on the computer processor, performs an operation for processing data, comprising;

receiving a fault event indication from a vehicle;

determining an amount of time that has elapsed since the vehicle previously output the fault event indication;

determining a fault event resolution time period for the received fault event indication;

including the fault event indication in a total number of instances of the fault event indication only if the determined amount of time is greater than the determined fault event resolution time period for the received fault event indication;

upon receiving an indication that a service interruption occurred as a result of the fault event indication, including the service interruption in a total number of instances of service interruptions that occurred as a result of the fault event indication;

calculating the probability of a service interruption for the fault event for the vehicle based on the total number of instances of the fault event for the vehicle and the total number of instances of service interruptions for the fault event for the vehicle; and

outputting the calculated probability of a service interruption for the fault event.

9. The system of claim 8, wherein the program performs an additional operation for processing data, comprising:

upon the calculated probability of a service interruption exceeding a predetermined threshold level;

automatically generating a fault event message; and

transmitting the fault event message to an operator of the vehicle.

10. The system of claim 9, wherein automatically generating the fault event message comprises:
