A Longitudinal Study And Color Rating System Of Acquisition Cost Growth, Cory N. D'Amico
A Longitudinal Study And Color Rating System Of Acquisition Cost Growth, Cory N. D'Amico
Theses and Dissertations
different angles have been looked at to try and discover how to better estimate cost, what causes cost growth, and how to mitigate it. This research addresses this through examining cost growth from a longitudinal perspective, evaluating cost growth factors at major program reviews, and assessing the cost growth by applying color rating metrics. The results of this analysis show that breaking cost growth into longitudinal segments of a programs lifecycle allows the true behavior of cost growth to be seen, when it can often be masked in the traditional approach of evaluating lifecycle cost growth. Additionally, when applying the …
Smoking In The United States Air Force: Trends, Most Prevalent Diseases And Their Association With Cost, Michail Gkoutouloudis
Smoking In The United States Air Force: Trends, Most Prevalent Diseases And Their Association With Cost, Michail Gkoutouloudis
Theses and Dissertations
This research focuses on the smoking rates among the Active Duty Air Force (ADAF) personnel and the association of smoking and cost of hospitalization because of diseases related to smoking. Three types of analyses were used in this research. The Contingency Analysis was based on the data taken from the Air Force Web HA questionnaire. The Pivot Table Analysis and the Regression Analysis were based on a second data set associated with the cost of hospitalization. The Contingency Analysis showed that smoking in the U.S. Air Force is more prevalent among the enlisted, males, and the younger age groups. The …
Forecasting Flying Hour Costs Of The B-1, B-2, And B-52 Bomber Aircraft, Stefanie L. Van Dyk
Forecasting Flying Hour Costs Of The B-1, B-2, And B-52 Bomber Aircraft, Stefanie L. Van Dyk
Theses and Dissertations
This thesis both evaluates, and presents improvements to, the current method of forecasting flying costs of Air Force aircraft. It uses depot level repairable (DLR) and consumable (CONS) data for the Air Force's bomber platforms: B-1B, B-2, and B-52H. The current forecasting method assumes a proportional relationship between costs and flying hours such that 1) when no hours are flown costs are zero, and 2) a 1% increase in flying hours will increase costs by 1%. The findings of this research indicate that applying log-linear ordinary least squares regression techniques may be an improved fit of flying cost data over …
Creating Cost Growth Models For The Engineering And Manufacturing Development Phase Of Acquisition Using Logistic And Multiple Regression, Brandon M. Lucas
Creating Cost Growth Models For The Engineering And Manufacturing Development Phase Of Acquisition Using Logistic And Multiple Regression, Brandon M. Lucas
Theses and Dissertations
Cost growth remains a concern for cost analysts, program managers, senior DoD decision-makers, Congress, and even the American public. All of these people have a vested interest in the cost of DoD programs and most would like to see those costs decrease; as such, we need additional tools to help combat cost growth. Previous research creates the foundation for the use of a two-step methodology to help predict cost growth, which we follow closely. First, utilizing logistic regression we analyze whether specific program characteristics predict cost growth within the Engineering and Manufacturing Development (EMD) phase for combined RDT&E and procurement …
Logistic And Multiple Regression: A Two-Pronged Approach To Accurately Estimate Cost Growth In Major Dod Weapon Systems, Matthew B. Rossetti
Logistic And Multiple Regression: A Two-Pronged Approach To Accurately Estimate Cost Growth In Major Dod Weapon Systems, Matthew B. Rossetti
Theses and Dissertations
This research confirms the usefulness of the logistic and multiple regression two-step procedure for assessing cost growth in major DoD weapon systems. We compile programmatic data from the Selected Acquisition Reports (SARs) between 1990 and 2002 for programs covering all defense departments. Our analysis concentrates on cost growth in the procurement appropriations of the Engineering and Manufacturing Development phase of acquisitions. We investigate the use of logistic regression in cost growth analysis to predict whether or not cost growth will occur in a program. If applicable, multiple regression is implemented to predict how much cost growth will occur. Our study …
