Abstract:

This report describes two methods of estimating the production costs of jet engines not yet built 1 By building up the costs of the cost driving parts in a traditional Industrial Engineering fashion and 2 By using regression techniques to estimate either entire engine costs RAND approach or parts of engines. The report concludes that both methods are feasible though the former has a greater theoretical accuracy. Potential problems of accounting for changes in performance and schedule may well give the second method the edge in practical application on the bases of cost, speed and speed of implementation.
