Purchasing And Supply Chain Management Costing: An Air Transport Perspective Derived Through Commercial Air Cargo Firms, Kurt Ettrich Mar 2004

Purchasing And Supply Chain Management Costing: An Air Transport Perspective Derived Through Commercial Air Cargo Firms, Kurt Ettrich

Theses and Dissertations

The Air Force has struggled to completely understand the costs associated with its operations. The issue of understanding cost is complex, involving many perspectives, methods and techniques. When examined from a broad standpoint, total supply chain costs can include a firm's costs plus upstream and downstream costs. This perspective takes vendors, suppliers and end customers into consideration. From this broad standpoint, the Air Force does not know its total supply chain cost. Since the Air Force's supply chain is too broad to be a focus of this study, a smaller segment was chosen for a closer look. Specifically, air cargo …


Decision Analysis With Value Focused Thinking As A Methodology To Assess Air Force Officer Retention Alternatives, Sang-Ho Moon Mar 2004

Decision Analysis With Value Focused Thinking As A Methodology To Assess Air Force Officer Retention Alternatives, Sang-Ho Moon

Theses and Dissertations

Many countries realize the importance of the retention of qualified military personnel, and have tried to solve this problem using various methods. Nevertheless, the effects of those methods have not been determined or proven yet. The military retention problem is closely related to each individual's separation decision from the military. The characteristics of this decision are multi-objective and highly subjective. Accordingly, the effectiveness of various methods is heavily dependant on the value set of each individual. Decision Analysis (DA) using Value Focused Thinking (VFT) can be an excellent process to deal with this decision. Also, the data can reflect the …

Analysis And Forecasting Of Army Operating And Support Cost For Rotary Aircraft, John C. Hawkins Mar 2004

Analysis And Forecasting Of Army Operating And Support Cost For Rotary Aircraft, John C. Hawkins

Theses and Dissertations

This research explores forecasting techniques to estimate the Cost per Flying Hour (CPFH) for Army Helicopters. Specifically, three separate forecasting techniques were evaluated to better predict the CPFH for better estimating and budgeting by the U.S. Army. For forecasting purposes, actual CPFH figures were compiled from 1995 to 2003 for all MACOMs flying the AH-64A, the CH-47D, and the UH-60A helicopters. The number of MACOMs was then reduced to the top three with regard to total CPFH expenditure. The use of a 3-year moving average, the single exponential smoothing method, and Holt's linear method were explored for each helicopter's data. …


A Demand Side Requirements Model To Forecast C-17 Mobility Aircraft Availability, Joseph R. Huscroft Jr. Mar 2004

A Demand Side Requirements Model To Forecast C-17 Mobility Aircraft Availability, Joseph R. Huscroft Jr.

Theses and Dissertations

Current aircraft forecasting methods of the Air Mobility Command (AMC) Directorate of Logistics are reliant on the experience of personnel and lead to after the fact, labor-intensive analysis. These deficiencies led AMC to the development of a Mobility Aircraft Availability Forecasting (MAAF) model. The purpose of the MAAF model is threefold: predict aircraft availability in order to provide the Tanker Airlift Control Center (TACC) with a forecast of aircraft that will be available for AMC mission requirements, provide what if capabilities that analyze the effects of tasking and policy changes, and to provide foresight into problems associated with aircraft availability …

Developing Team Cohesion: A Quasi-Field Experiment, John F. Costello

Theses and Dissertations

Within military organizations, research findings have lent support to the positive influence cohesion has on group performance in combat and non-combat areas, Beyond performance, research findings show that cohesion influences the job satisfaction, and health of military members, particularly under highly stressful conditions, such as those encountered in combat or extended deployments. The purpose of this research effort is to further analyze the strategies that should be used to develop cohesiveness among Air Force members. This was done by testing the extent to which cohesion changed when familiarization and challenging situations were coupled in a technical training course geared towards …


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. …


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 …


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 …

Building Relationships That Last: Integrating Public Relations Into Web Design, Richard V. Mccarthy, Jay E. Aronson, Robert Petrausch Jan 2004

Building Relationships That Last: Integrating Public Relations Into Web Design, Richard V. Mccarthy, Jay E. Aronson, Robert Petrausch

Journal of International Technology and Information Management

This paper explores the relationship between web site design, public relations strategy, and a consumer’s intention to return to a web site. This relationship is defined through a model that explores the influence of information satisfaction, particularly when the web site design is congruent with the consumer’s expectations. The public relations dimension extends the consumer web site design model by interjecting a long-term focus on relationship building that organizations will need to make electronic commerce a viable investment in information technology resources. This is significant because it recognizes the importance of developing loyalty and trust online.

Deciding On The Appropriateness Of B2b Reverse Auction Technology Adoption: An Ahp Approach Combined With Integer Programming, Tobias Schoenherr Jan 2004

Deciding On The Appropriateness Of B2b Reverse Auction Technology Adoption: An Ahp Approach Combined With Integer Programming, Tobias Schoenherr

Journal of International Technology and Information Management

Although Business-to-Business online reverse auctions have emerged as a promising purchasing tool, no research has been found that provides a model to assess the reverse auction decision in a systematic way. This paper fills this gap by presenting an integrated approach, utilizing Analytic Hierarchy Process techniques and an Integer Programming Formulation, to decide whether Reverse Auction Technology (RAT) adoption is cost-effective and appropriate. The model developed is a practical decision support tool that allows for the consideration of both qualitative and quantitative decision factors, and for the adoption of multiple modes of RATs, which are contrasted to traditional purchasing.
