This thesis explored the impact of heroic actions on depot maintenance operations in terms of aircraft flow days through programmed depot maintenance and in terms of lost production hours. In an area of fiscal uncertaintly and reducing budgets, an understanding of the impact of heroic actions would lead to efficiency gains for the Air Force. Depots do not routinely report the associated impact of heroic actions on their operations and recent efforts to assess these impacts have not arrived to a definitive conclusion.

To assess the impact of heroic actions on depot processes, a discrete event simulation was developed for the KC-135 depot operations and heroic actions. Two scenarios were developed and relative impact of heroics was assessed. A baseline case was created with the intent to model current operations and an alternate scenario was developed based on the premise that additional funds for part procurement would reduce the flow day and production hour impact of heroics. An analysis of these scenarios shows that reducing the frequency of heroic actions does significantly impact KC-135 flow days and lost production hours.
