Estimating Scale Up Cost Factors for Commercial Jet Planes

Document Type



Computer Science (HMC)

Publication Date



A parametric scale-up cost factor study for commercial jets is presented. Three independent variables were used to correlate costs to the customer: maximum take-off weight, number of seats, and length of the plane. Scale-up cost factors for each of these variables are presented, based on data collected on 34 planes from the three largest manufacturers of commercial jet aircraft: Airbus, Boeing, and Embraer. The scale-up factors developed in this research are now being used in industry to estimate the costs for commercial jet planes and to calibrate commercial parametric cost estimation models.
