INVESTIGATION OF LEARNING CURVE AND COST ESTIMATION METHODS FOR CARGO AIRCRAFT.

Abstract

Learning curves are developed for nine cargo aircraft using log-linear, log-quadratic, and log-cubic forms with best results being obtained with the log-quadratic. Estimating relations for the prediction of new aircraft costs are derived using current methods and tested for accuracy on the original sample and on the C-141A; a cost prediction for the C-5A is also obtained. Predictions were also obtained using a recent RAND Corporation developed equation. Predictive accuracy in all cases was poor and the conclusion was reached that present methods are inadequate for the estimation of direct-labor costs. (Author)
