Abstract : Currently mobile C-E War Readiness Spares Kit (WRSK) computations are not automated. They are determined during an annual meeting attended by system users and suppliers. However, the Air Force continues to study several methods and models to automate the process. This thesis reports validation results of one model. The model combines the operating and non-operating failure rates to predict C-E system failures for a specified period of time. This model uses operating failures distributed over operating hours and non-operating failures distributed over system power-up attempts. Validation results showed this model predicted C-E failures as good as current methods during periods of steady-state, long operating hours; however, it more accurately predicted failures during periods where operating and non-operating failures occurred. Therefore, the model can be applied to Air Force C-E WRSK computations. HQ USAF/LEYS should develop a policy to ensure C-E system users document the necessary data for application of this model.
