Model for Estimating Depot Maintenance Costs for Air Force Fighter and Attack Aircraft

摘要

The model developed in this study has two cost estimating relationships (CERs) for estimating depot maintenance costs in its two categories: depot maintenance cost per Promary Authorized Aircraft (PAA); and, depot maintenance cost per flying hour. The data source used for depot maintenance costs is the Weapon Systems Cost Retrieval System (WSCRS) as developed by HQ AFLC. The CERs developed used empty weight of fighter and attack aircraft to predict the cost of depot maintenance per PAA. For depot maintenance cost per flying hour, the variables used were combat radius, thrust-to-weight ratio, and empty weight. The study found that the F-111 was a significant outlier with respect to the data set, but even when included in the data base the F-111 enhanced the values of the statistics for the model and improved the ability of the model to predict. The relationship found for depot maintenance cost per PAA in the CER developed, was not as strong a predictor as was the CER developed for depot maintenance cost per flying hour. This conclusion agrees with previous studies that have tried to determine significant relationships between depot maintenance costs and those costs attributed to the number of PAA. (Theses).
