Evaluation Of Air Force Aircraft Maintenance Metrics For Integration Into The Expeditionary Combat Support System, Brian D. Waller Mar 2009

Evaluation Of Air Force Aircraft Maintenance Metrics For Integration Into The Expeditionary Combat Support System, Brian D. Waller

Theses and Dissertations

All organizations face the continuous challenge of a dynamic and ever-changing operations environment. They must adapt to new paradigms quickly or end up on the road to obsolescence. Never has this been truer for the U.S. Air Force than in the 21st century. The logistics organization of the Air Force supports a worldwide, 24/7 operation, executing the national directive of US Policy. Past logistics operation policies have now been proven to no longer be sufficient to meet the needs of the war-fighter. Shrinking budgets, aging equipment, and the austere, disparate operating locations demand sweeping changes in how the logistic machine …


Reducing Cannon Plug Connector Pin Selection Time And Errors Through Enhanced Data Presentation Methods, Robert R. Webb Sep 1997

Reducing Cannon Plug Connector Pin Selection Time And Errors Through Enhanced Data Presentation Methods, Robert R. Webb

Theses and Dissertations

The purpose of this research is to investigate the effects of data presentation methods on technician performance when the procedures are presented on a monocular, head mounted display (HMD) in a static maintenance environment. This research used two different methods to present the maintenance task data to the technicians. The first method showed the task as it is typically described in standard technical manuals. It described the task to perform and provided a basic picture of the cannon plug to be tested (unenhanced). The second method provided the same information as the first, but it also modified the information by …


Prioritization Schemes Of The Air Force Logistics Reparable Pipeline, Brigham K. Briggs Sep 1996

Prioritization Schemes Of The Air Force Logistics Reparable Pipeline, Brigham K. Briggs

Theses and Dissertations

This study describes the prioritization schemes utilized in the Air Force logistics reparable pipeline. The reparable pipeline is defined and illustrated with flowcharts. A literature review examines previous research conducted on the reparable pipeline, including analytic and conceptual pipeline models, and pipeline management studies. In addition, the topic of prioritization as defined in the production/operations management academic discipline is reviewed. Prioritization schemes of the reparable pipeline are reported in tabular format in addition to descriptions of the various prioritization schemes. Recommendations for pipeline improvement and further research form a basis from which pipeline operation may be improved. p9


Assessing User Requirements For An Automated System To Support Programmed Depot Maintenance Through Use Of A Rapid Prototype In A Group Support System Environment, Floyd A. Gwartney Sep 1996

Assessing User Requirements For An Automated System To Support Programmed Depot Maintenance Through Use Of A Rapid Prototype In A Group Support System Environment, Floyd A. Gwartney

Theses and Dissertations

The purpose of this thesis was to assess user requirements for an automated information system to support programmed depot maintenance (PDM). To accomplish this, the Integrated Technical Information for the Air Logistics Centers (ITI-ALC) program's rapid prototype was evaluated. The evaluation focused on users' perception of how well the prototype met system and human computer interface requirements for PDM technicians and managers. A group support system (GSS) was used as an analysis tool to evaluate the prototype and collect evaluation data. Using the prototype as a requirements baseline for the ITI-ALC system, this thesis had three objectives: to perform an …


An Investigation Into Aircraft Availability, Michael S. Kapitzke Sep 1995

An Investigation Into Aircraft Availability, Michael S. Kapitzke

Theses and Dissertations

The Air Force currently uses an expected value model in the Aircraft Availability Model (AAM) to calculate aircraft availability. However, even with the application of Lean Logistics, the failure-demand rate and the depot repair time are not fixed and the mean value is still used in the model. This research looks at the effect of the magnitude of the variance of the distributions of failure-demand rate and depot repair time. Also, this research evaluates the effect of variable mean failure-demand rates on the variability of aircraft availability. A simulation model was developed which applied the variable failure-demand rates and depot …


Demonstrating The Effects Of Shop Flow Process Variability On The Air Force Depot Level Reparable Item Pipeline, Marvin A. Arostegui Jr., Jon A. Larvick Sep 1992

Demonstrating The Effects Of Shop Flow Process Variability On The Air Force Depot Level Reparable Item Pipeline, Marvin A. Arostegui Jr., Jon A. Larvick

Theses and Dissertations

This study investigated the effects of reducing the mean processing time and variability in the Shop Flow Segment of the Depot Level Reparable Item pipeline. The measure of interest was the average number of units in the pipeline of a particular type of item (referred to as the average pipeline contents). A literature review revealed that process variability in the pipeline has an impact on its effective operation and cost. A simulation model was developed to determine if reducing mean processing time and/or variability in the Shop Flow Segment would result in a reduction in the average pipeline contents. The …


A Comparison Of Aircraft Maintenance Organizational Structures, Wesley C. Davis, Sanford Walker Sep 1992

A Comparison Of Aircraft Maintenance Organizational Structures, Wesley C. Davis, Sanford Walker

Theses and Dissertations

This study compares the aircraft maintenance structure being implemented by General Merrill A. McPeak with that of the previous structure typified by TACR 66-5. Historical aircraft data is used to compare organizational structures. Data from the USAF and USN is used to build regression models to determine if organizational structure contributes to combat capability. Statistical tests are used to determine if a significant difference exists between the two organizational structures. Regression analysis and comparison of the results lead the researchers to conclude that a significant difference exists in the performance measures of COMO and Objective Wing organizations. While many reasons …
