Reliability of Progress Curves in Airframe Production. Revision 3
Abstract
The airframe manufacturing progress curve estimates direct labor per pound of airframe needed to manufacture the Nth airframe, from N, the cumulative number of planes of a given model produced at a given facility. The relation is customarily written as a linear function between the logarithm of direct labor per pound and the logarithm of the Nth airframe. Statistical tests of the similarity of the functions among various airframe manufacturers, on the basis of reported World War 2 data, have been made in this paper. An assessment has also been made of the reliability of predictions made with these curves. The functions are shown to differ among the various airframe types and manufacturing facilities both in the amount and rate of change of required labor per pound of airframe.
