VALIDATION OF DISCARD-AT-FAILURE MAINTENANCE MATHEMATICAL MODEL
Abstract
A description is presented of the procedure and results of an investigation to perform an empirical validation of a repair-at-failure maintenance (RAFM) versus discard-at-failure maintenance (DAFM) mathematical modeling technique. In general, the effort met all but one objective successfully. The extent to which complete and rigid statistical testing of model prediction accuracy was limited by the type and quantity of the cost data sample available on the study equipment. A resource cost field data collection and analysis was conducted on a number of operation AF ground and airborne electronic equipments to determine the degree to which model revisions would be necessary to achieve validity. Seven major changes were identified and incorporated. The revised model's validity and prediction capability were demonstrated by application to an airborne electronic equipment. It was concluded that RAFM for the AN/ASG-19 study test vehicle was more economical than DAFM for the existing maintenance and logistic support environment.
