Abstract

In order to manage essential parts that are required for the repairable parts services performed at the military maintenancedepots, the United States Air Force developed the Repairability Forecasting Model (RFM). In the RFM, if the requirementsof the parts are assumed to follow the normal probability distribution after applying means from the past data to the replacementrate and lead times, the chance of the AWP (Awaiting Parts) occurring is 50%. In this study, to counter the uncertainties ofrequirements and lead times from the RFM, the safety level concept is considered. To obtain the safety level for requirements,the binomial probability distribution is applied, while the safety level for lead time is obtained by applying the normal probabilitydistribution. After adding this concept, the improved RFM is renamed as the ARFM (Advanced RFM), and by conducting thenumerical stimulation, the effectiveness of the ARFM, minimizing the occurrence of the AWP, is shown by increasing the efficiencyof the maintenance process and the operating rate of the weapon system.
