Abstract: A method of projecting aircraft maintenance costs is disclosed and includes generating a plurality of reliability models associated with a plurality of aircraft mechanical systems. The method also includes performing a plurality of simulations, where each simulation is related to operating one of the plurality of aircraft mechanical systems over a period of time and each simulation based on one of the plurality of reliability models. The method also includes projecting a maintenance cost of each of the plurality of aircraft mechanical systems over the period of time based on each simulation. The method also includes determining a total maintenance cost of the plurality of aircraft mechanical systems over the period of time based on the maintenance cost of each of the plurality of aircraft mechanical systems over the period of time.

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.

Abstract: A method is provided that includes receiving a primary work scope comprising a set of tasks associated with maintenance of the mechanical system including a life-limited part. The method further includes generating a set of work scopes for the mechanical system, where each work scope of the set of work scopes includes the primary work scope and at least one additional task associated with maintenance of the mechanical system. At least one work scope of the set of work scopes includes a maintenance task related to the life-limited part. The method further includes estimating an operating time and a cost performance parameter for the mechanical system based on each work scope of the set of work scopes and providing an enhanced work scope. The enhanced work scope has an operating time that is greater than a threshold.

Abstract: This disclosure is directed to a method to enhance cost performance of a mechanical system. The method includes inspecting the mechanical system to determine a primary work scope. The primary work scope is associated with a first subset of the set of modules. The method further includes accessing a computational system configured to determine an enhanced work scope associated with the first subset and a second subset of modules. The enhanced work scope is determined based on expected cost per unit operation time of the mechanical system. The method also includes performing tasks associated with the enhanced work scope on the mechanical system.
