System and method of troubleshooting aircraft system failures
First Claim
1. A method of troubleshooting a mechanical system, the method comprising:
- receiving a maintenance request;
determining a plurality of maintenance tasks related to the maintenance request;
determining a first expected cost of implementing the plurality of maintenance tasks in a first order;
determining a second expected cost of implementing the plurality of maintenance tasks in a second order; and
selecting an implementation order for the plurality of maintenance tasks based at least in part on the first and second expected costs.

Abstract
A method of determining a preferred order of implementing maintenance tasks and determining a plurality of maintenance tasks related to a received maintenance request is disclosed. A first expected cost of implementing the plurality of maintenance tasks in a first order and a second expected cost of implementing the plurality of maintenance tasks in a second order are determined. An implementation order for the plurality of maintenance tasks is selected based at least in part on the first and second expected costs. Expected costs may be determined based at least in part on the cost of implementing each maintenance task and based on the probability that the problem has not yet been addressed by preceding tasks.

10. A method of troubleshooting mechanical system failures, the method comprising:
-
identifying a plurality of tasks to repair a mechanical system; determining a cost of implementing each task of the plurality of tasks; determining a probability that each task of the plurality of tasks will repair the mechanical system; determining a proposed order of implementing the plurality of tasks; and determining an expected cost of repairing the mechanical system based on the cost of implementing each task and a probability that the mechanical system has not been repaired by preceding tasks in the proposed order, wherein the probability that the mechanical system has not been repaired by preceding tasks is based on the probability that each task of the plurality of tasks will repair the mechanical system.

11. A work scope to troubleshoot a mechanical system, the work scope comprising:
a plurality of maintenance tasks sorted in a preferred implementation order;
wherein the preferred implementation order is selected from a plurality of implementation orders based on an expected cost of implementing the plurality of maintenance tasks, the expected cost based on a cost of implementing each maintenance task and a probability that each maintenance task will correct or identify a problem with the mechanical system.
