Location Optimization Of Continental United States Strip Alert Sites Supporting Homeland Defense, Jon A. Eberlan Mar 2004

Location Optimization Of Continental United States Strip Alert Sites Supporting Homeland Defense, Jon A. Eberlan

Theses and Dissertations

With the dissolution of the Warsaw Pact and the fall of the Soviet Union, the number of alert aircraft dwindled to 14 aircraft located at 7 sites on September 11, 2001. After the terrorist attacks on the World Trade Center Towers and the Pentagon, the United States could not continue to endorse an outward looking air defense strategy. Terrorism completely changed the landscape of the air defense mission. This research develops a location optimization model to optimally locate alert sites post-11 September to cover areas of interest in the CONUS. The model finds the minimum number of alert sites, minimum …

Value-Focused Thinking In The Presence Of Weight Ambiguity: A Solution Technique Using Monte Carlo Simulation, Timothy W. Porter Mar 2004

Value-Focused Thinking In The Presence Of Weight Ambiguity: A Solution Technique Using Monte Carlo Simulation, Timothy W. Porter

Theses and Dissertations

When a Decision Maker is asked to provide his or her preferences, the response represents a snapshot in time. While their preference structure elicited at any given moment may represent their revealed preferences at that point in time, it may change over time. These changing preferences over time represent ambiguity in the decision maker's preferences. Other sources of ambiguity may exist. One weakness of many decision analysis techniques today is the inability to incorporate ambiguity into the basic decision model. The existence of the problem has been known and commented on for many years. This research addresses that problem. It …

Identifying The Benefits Of Knowledge Management In The Department Of Defense: A Delphi Study, David P. Sasser Mar 2004

Identifying The Benefits Of Knowledge Management In The Department Of Defense: A Delphi Study, David P. Sasser

Theses and Dissertations

Knowledge Management (KM) has been identified as one of several enablers of the current Transformation effort in the Department of Defense (DoD). Knowledge management is "the attempt to recognize what is essentially a human asset buried in the minds of individuals, and leverage it into an organizational asset that can be accessed and used by a broader set of individuals on whose decisions the firm depends" (Davenport & Prusak, 1998). The ultimate goal of KM is to take advantage of this knowledge asset in order to provide some level of benefit to the organization (Davenport & Prusak, 1998; Nonaka, 1996). …

Logistic And Multiple Regression: The Two-Step Approach To Estimating Cost Growth, Daniel C. Genest Mar 2004

Logistic And Multiple Regression: The Two-Step Approach To Estimating Cost Growth, Daniel C. Genest

Theses and Dissertations

This study sought to predict cost growth in major Department of Defense (DoD) acquisition programs using logistic and multiple regression. In recent years, the use of statistical regression has proven to be successful in predicting the relationships associated with cost growth. This research follows on the work of Sipple (2002) and Bielecki (2003) and further explores the possibilities of using statistical regression to accurately estimate the dollar value associated with risk and uncertainty early in a program's life cycle. In doing so, the author intends to reduce cost growth by increasing the accuracy of the original cost estimates subsequently used …

Creating Cost Growth Models For The Engineering And Manufacturing Development Phase Of Acquisition Using Logistic And Multiple Regression, Brandon M. Lucas Mar 2004

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 …

Comparative Analysis On The Cost Of Oversight For The New National Security Space Acquisition Policy- A Delphi Method Approach, Darrin L. Dereus Mar 2004

Comparative Analysis On The Cost Of Oversight For The New National Security Space Acquisition Policy- A Delphi Method Approach, Darrin L. Dereus

Theses and Dissertations

For the past 50 years, the military's use of space for our national defense has increased exponentially. The use of space has increased so much that recent events have led to the approval for most space Major Defense Acquisition Programs to fall under their own process of oversight to track and monitor these programs. The largest reason for this change is due to the difference in spending profiles and current acquisition regulations that are not structured to meet these space expenditure plans. The key problem is no one knows, for sure, how much the oversight process actually costs and if …

An Analysis Of Depot Repair Capacity As A Criterion In Transportation Mode Selection In The Retrograde Movement Of Reparable Assets, Harold M. Kahler Mar 2004

An Analysis Of Depot Repair Capacity As A Criterion In Transportation Mode Selection In The Retrograde Movement Of Reparable Assets, Harold M. Kahler

Theses and Dissertations

To support smaller reparable asset inventories, current Air Force supply and transportation policies direct the expedited evacuation of reparables by bases and deployed units to the source of repair. Mode selection is based on the asset. Focusing on the asset and moving it quickly is an efficient and effective method of getting assets to where they are needed in a timely manner in the forward portion of the supply pipeline. However, in the reverse portion of the pipeline, the demand for a particular type of asset may no longer be the most important factor in how it is transported. The …

Mitigating Growth Cost For Mobility Readiness Spares Packages, Stephen D. Gray Mar 2004

Mitigating Growth Cost For Mobility Readiness Spares Packages, Stephen D. Gray

Theses and Dissertations

A Mobility Readiness Spares Package (MRSP) is an air-transportable package of spare parts configured for rapid deployment in support of conflict or war. Each package is tailored to support a specific scenario, for a specific type and number of aircraft without re-supply for the first 30 days of deployment. Inventory is limited to mission-critical spares. The high cost of airlift and spares drive a necessity to keep MRSPs as small as possible, yet robust enough to meet wartime goals. Historical MRSP inventories exhibit significant volatility and the subsequent growth of their inventory creates significant cost to the Air Force. Annual …

Effects Of Duty Schedule Variance And Overtime On The Job Satisfaction And Turnover Intentions Of Usaf F-16 Crew Chiefs, Michael J. Shellhamer Mar 2004

Effects Of Duty Schedule Variance And Overtime On The Job Satisfaction And Turnover Intentions Of Usaf F-16 Crew Chiefs, Michael J. Shellhamer

Theses and Dissertations

This thesis empirically assessed how duty schedule variance and overtime affect the job satisfaction and turnover intentions of USAF F-16 crew chiefs. A survey was completed by 346 active duty USAF F-16 crew chiefs regarding their perceptions of duty schedule variance, overtime, job satisfaction and intent to leave the Air Force. Theory suggests that turnover behavior is a multistage process that involves organizational, individual, and attitudinal components. Using multivariate correlation and regression analyses, plausible evidence was found to support the idea that duty schedule variance and overtime plays a role in USAF F-16 crew chief turnover intentions via job satisfaction. …

The Impacts Of Delphi Communication Structure On Small And Medium Sized Asynchronous Virtual Teams, Hee-Kyung Cho Jan 2004

The Impacts Of Delphi Communication Structure On Small And Medium Sized Asynchronous Virtual Teams, Hee-Kyung Cho

Dissertations

The improvement of Internet technology has motivated distributed work groups to collaborate without meeting face to face. Although asynchronous meetings through Web-based group communications systems enable groups dispersed temporarily and geographically to collaborate more flexibly, parallel and non-linear communication among dispersed members also challenge effective and efficient group coordination. Moreover, the Web-based asynchronous meeting is distinguished not only from the face-to-face meeting but also from the synchronous computer-supported meeting in terms of coordination process. However, previous asynchronous group communications or virtual team research focused more on the comparison of this new type of meeting with the face-to-face meeting. Not many …

The Effect Of Tourist Theft On Future Travel Decisions, Judith Lynn Holcomb Jan 2004

The Effect Of Tourist Theft On Future Travel Decisions, Judith Lynn Holcomb

Electronic Theses and Dissertations

Past research has shown that theft is a prevalent crime against tourists. This study's purpose was to determine the effects of past incidents of personal theft on tourists' future decisions to travel by analyzing and comparing those who have experienced personal theft to those who heard of such incidents through personal accounts of friends or family. The findings, which were taken from a survey of 215 respondents, revealed that that experiencing personal theft, or knowing of someone who has, is not a deterrent for visiting a destination where the theft occurred. Results also showed that one aspect of theft that …

The Effects Of Asset Allocation And Active Management On Total Return Of Managed Funds, Florian Halili Jan 2004

The Effects Of Asset Allocation And Active Management On Total Return Of Managed Funds, Florian Halili

Business and Economics Honors Papers

Portfolio managers are charged with maximizing returns for a given level of risk. There are practical problems that arise in creating an efficient portfolio and maintaining a target level of risk and return. This paper will identify two important factors that a manager needs to address in creating and managing a portfolio. The first step in creating a portfolio should be the establishment of the structure of the portfolio or the portfolio policy, what asset classes it holds and in what proportions. The structure of the portfolio is the main factor that shows how a portfolio is exposed to risk. …
