Developing A Rule-Of-Thumb To Predict Total O&S Costs Utilizing A Single Ces Element, Shane A. Scantling
Developing A Rule-Of-Thumb To Predict Total O&S Costs Utilizing A Single Ces Element, Shane A. Scantling
Theses and Dissertations
A rule of thumb is a broadly accurate guide based on experience rather than theory. This study examines the potential for a rule of thumb to predict Operation and Sustainment (O&S) costs. The Center for Naval Analysis (CNA) found that a single variable could accurately predict total O&S costs. We found that while a single variable could be highly predictive and strongly correlated to total O&S costs, it is not the same variable for all platforms. We improved upon this initial heuristic proposed by Stumborg by developing an individual heuristic for each Mission Design (MD). We found that a form …
