A Parametric Estimating Model for Flight Simulator Acquisition

The purpose of this study was to develop a parametric cost estimating model that would accurately predict the first unit cost of aircraft flight simulators. It was found that significant cost estimating relationships (CERs) exist between cost and simulator system characteristics, all of which can be identified in the conceptual stage of the weapon system acquisition. Using a data base created from existing aircraft flight simulator programs, various CERs were developed under a multiple linear regression process. Statistical tests were performed and prediction intervals were developed in order to determine which CER was the best predictor of aircraft flight simulator first unit costs. Based on this procedure, one CER was determined to be a better predictor than any other and was recommended to be used as an estimating tool for the future. (Author)
