Abstract:
Fourier analysis encompasses both the decomposition of a function into simpler pieces, often called “analysis”, and the corresponding operation of rebuilding the function from those simpler pieces, referred to as “synthesis”. While often used as a tool in analyzing harmonic functions, Fourier analysis methods can also be used to investigate and determine contributions of various components to a more complex output function.
The basic concept of this effort is that a Program Office Estimate consists of a number of functions related to the contribution of individual cost elements. The use of Cost Estimating Relationships (CERs) and other variable-based functions in its development gives a sound basis for approaching a POE as a complex function. When incorporating proposed, contractual, and actual inputs, it is possible that such an analysis could yield more accurate CERs based on outputs using historical cost data.
This effort proposes to determine and validate an approach to applying Fourier analysis methods to a theoretical cost data set and then apply that approach to analyze select historical standard Department of the Army Program Office Estimate Cost Elements.
