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.
