Research and Calibrate the Logistics Support Cost Model Out of Production Factor

摘要

This thesis reviewed the statistical significance of the Logistics Support Cost (LSC) Model Out of Production Factor (OOPFAC) which is used to compute aircraft and missile spare parts costs during the support phase of a weapons systems life cycle. The review was composed of two major areas. First, the review computed statistics for four groups of avionic spare parts to determine if there was a single OOPFAC or if multiple OOPFACs were required for estimating. Although not totally conclusive, the results indicated that more than one OOPFAC should be used for cost estimating. Second, the OOPFACs computed from the recent data were compared using statistical tests to the original OOPFAC developed over seven years ago. The statistical test rejected the use of the original factor. As a result of this investigation, the OOPFAC should be updated in all Air Force cost estimating models to incorporate the newly computed factors.
