An Evaluation Of The Software Engineering Institute's Capability Maturity Model As A Framework For Software Process Improvement At Three Air Logistics Centers, Brian G. Hermann, Raymond J. Lewis Jr. Dec 1993

An Evaluation Of The Software Engineering Institute's Capability Maturity Model As A Framework For Software Process Improvement At Three Air Logistics Centers, Brian G. Hermann, Raymond J. Lewis Jr.

Theses and Dissertations

This research sought to determine whether a relationship exists between the maturity level of the software process, as determined by the Software Engineering Institutes Capability Maturity Model SEI CMM, and the actual success of particular software projects at three US Air Force Air Logistics Centers. Project success is defined in terms of cost, schedule, and quality criteria. In addition, each organizations acceptance of the SEI assessment as well as its effectiveness in setting up follow-on process improvement programs were evaluated. Finally, the process improvement programs were reviewed individually inasmuch as these programs are the mechanisms for achieving improved quality, lower …


Automating Satellite Range Scheduling, S. Michael Schalck Dec 1993

Automating Satellite Range Scheduling, S. Michael Schalck

Theses and Dissertations

The objective of this study was to develop a computer based satellite range scheduling SRS algorithm to create a 24 hour satellite support schedule. The algorithms goal was to schedule as many satellite support requests as possible. An iterative heuristic approach was used to schedule satellite support requests in three successive sub problems. The first sub problem involves scheduling low altitude satellite support requests using a mixed integer programming approach. The next two sub problems each involve scheduling 12 hour blocks of medium and high altitude satellite support requests, again using a mixed integer programming approach. Fourteen 24 hour schedules …


Measuring User Satisfaction Of The Electronic Mail System At Air Force Materiel Command Headquarters As An Indicator Of The System's Effectiveness, Randall R. Bradford Dec 1993

Measuring User Satisfaction Of The Electronic Mail System At Air Force Materiel Command Headquarters As An Indicator Of The System's Effectiveness, Randall R. Bradford

Theses and Dissertations

The purpose of this study was to evaluate the effectiveness of the electronic mail system at the Air Force Materiel Command Headquarters. User satisfaction was measured as an indicator of the systems effectiveness. In order to provide an objective measurement of system effectiveness, the following research questions were addressed: (1) What is system effectiveness in relation to this particular electronic mail system, and how should it be measured? (2) What measurement instruments can be adapted, modified, or created to measure effectiveness as it is defined for problem? (3) If a measurement instrument is administered what do the results of the …


A Decision Support Model Using Life Cycle Cost (Lcc) Analysis To Select Cost-Effective Alternatives For Hazardous Materials, Blaine F. Burley, Kirk A. Phillips Sep 1993

A Decision Support Model Using Life Cycle Cost (Lcc) Analysis To Select Cost-Effective Alternatives For Hazardous Materials, Blaine F. Burley, Kirk A. Phillips

Theses and Dissertations

This research focuses on the development of a decision support model to select cost-effective alternatives for hazardous materials using life cycle cost (LCC) analysis. The model provides an effective decision-making tool to evaluate the economic feasibility of using alternatives for hazardous materials. Given a specific operation, the users of this model can enter site-specific cost data to determine the total LCCs of using baseline hazardous materials (i.e., hazardous materials currently being used in an operation), as well as the total LCCs of using various alternatives. This thesis postulates that the material having the lowest total LCC is considered to be …


An Analysis Of The Effectiveness Of The Air Force Drug Testing Program And Four Potential Modifications, Thomas R. Doster, Hubert A. Ross Sep 1993

An Analysis Of The Effectiveness Of The Air Force Drug Testing Program And Four Potential Modifications, Thomas R. Doster, Hubert A. Ross

Theses and Dissertations

This study evaluated the 1992 USAF Drug Testing Program and potential improvements, based on the number of drug users detected, cost, and legal issues. Four potential improvements were examined: (1) increasing the annual amount of random urinalysis; (2) increasing the proportion of commander-directed testing; (3) using a weighted selection technique, and (4) replacing urinalysis with hair testing. For each improvement, the researchers used test and survey results to estimate the number of drug users detected, a cost formula to estimate any changes in cost, and interviews with legal experts to identify any legal issues associated with implementing the modification. Researchers …


Software Cost Estimating Models: A Comparative Study Of What The Models Estimate, George A. Coggins, Roy C. Russell Sep 1993

Software Cost Estimating Models: A Comparative Study Of What The Models Estimate, George A. Coggins, Roy C. Russell

Theses and Dissertations

This effort developed a consolidated document which highlights and examines differences in definitions, assumptions, and methodologies used by the REVIC, SASET, PRICES, and SEER-SEM cost models. The following research questions were investigated: (1) What differences exist between the cost models? (2) How do these differences impact the resulting estimates? (3) To what degree can we explain and adjust for known differences between the cost models? Seven specific areas were addressed: (1) software development phases, (2) development activities and cost elements, (3) source lines of code and language differences, (4) key model attributes and key cost drivers, (5) implications of Project …


The Battle Of Little Round Top: An Analysis Of Battle Alternatives Through Commercial Wargames, John J. Mcguiness Mar 1993

The Battle Of Little Round Top: An Analysis Of Battle Alternatives Through Commercial Wargames, John J. Mcguiness

Theses and Dissertations

This thesis examines the problem of whether one can use commercial wargames as a tool for historical research. The research examines two wargames dealing with the battle of Little Round Top: Gettysburg: The Turning Point and Thunder at the Crossroads. This research emphasized the need to analyze the wargame's structure prior to playing the game. This will avoid a possible mistake of drawing a conclusion about a particular driver in the battle which may not be from the historical situation but rather an inevitable outcome produced by the model's basic assumptions. Additionally, quantitative measures of time lines, casualty rates, and …


An Analysis Of The Ability Of Commercial Wargames To Fulfill The Education Requirements Of The Air Force Wargaming Center, Scott Goehring Mar 1993

An Analysis Of The Ability Of Commercial Wargames To Fulfill The Education Requirements Of The Air Force Wargaming Center, Scott Goehring

Theses and Dissertations

It has been the contention of some that current commercial wargames could possibly fulfill the education requirements addressed by the Air Force Wargaming Center. The Wargaming Center, lacking the opportunity to conduct a thorough, in-house analysis of these commercial wargames, requested an independent evaluation be performed. This thesis identifies potential commercial wargames and provides an analysis of those wargames to determine their ability to educate senior military officers in the application of aerospace power. In addition, this thesis establishes a set of Measures of Effectiveness (MOEs) against which future wargames can be easily evaluated. The MOEs were developed from the …
