System and method of troubleshooting aircraft system failures
First Claim
1. A method comprising:
- receiving a maintenance request associated with a mechanical system;
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, wherein the second order is different from the first order; and
automatically selecting an implementation order from the first order and the second order based at least in part on a comparison of the first expected cost and the second expected cost.

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.

5. A 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.

6. A maintenance system comprising:
-
a work scope generator to determine a plurality of maintenance tasks based at least in part on symptoms of a mechanical system and to determine an implementation order of the plurality of maintenance tasks based on an expected cost of troubleshooting the mechanical system, wherein the implementation order is determined by the work scope generator based at least in part on a probability that each maintenance task of the plurality of maintenance tasks will correct the symptoms of the mechanical system and based at least in part on a cost of implementing each maintenance task of the plurality of maintenance tasks. - View Dependent Claims (7, 8, 9)
