Integration Of The Distribution And Repair In Variable Environments (Drive) Model Into Micap Policy, Bradley E. Anderson
Integration Of The Distribution And Repair In Variable Environments (Drive) Model Into Micap Policy, Bradley E. Anderson
Theses and Dissertations
The United States Air Force has implemented the Distribution and Repair In Variable Environments (DRIVE) Model to a limited degree for a limited range of items, and policy makers seem unsure as to the proper level of DRIVE utilization. New asset release sequences and policies have been proposed without evidence to support those decisions. The purpose of this study is to explore different levels of DRIVE implementation relating to proposed asset release policies in order to provide some evidence on which policy could best support Air Force weapon systems. A second purpose of this study is to show how the …
An Evaluation Of U.S. Air Force Aviation Fuel Consumption Factors To Accurately Predict Aviation Fuel Costs By Aircraft Mission, Design, And Series, Jodi A. Clayton
An Evaluation Of U.S. Air Force Aviation Fuel Consumption Factors To Accurately Predict Aviation Fuel Costs By Aircraft Mission, Design, And Series, Jodi A. Clayton
Theses and Dissertations
The purpose of this thesis was to undertake a systematic, scientific study of the accuracy of Air Force published fuel factors to estimate fuel costs at MAJCOM level by mission, design, and series (MDS) since the implementation of the Fuels Automated Management System (FAMS) under the current environment of decentralized aviation fuel (AVFUEL) funding. The research found that, at MAJCOM level, the use of USAF published AVFUEL factors in estimating out-year costs would have overstated costs in both fiscal year (FY) 1994 and FY 1995 by $2.5 M (FY 1994), by $.25 M (FY 1995), and may potentially understate costs …
Prioritization Schemes Of The Air Force Logistics Reparable Pipeline, Brigham K. Briggs
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
An Analysis Of Air Mobility Express Requirements Operating Within A Lean Logistics Wartime Environment, Jennifer A. Bollinger, Kellie L. Davila-Martinez
An Analysis Of Air Mobility Express Requirements Operating Within A Lean Logistics Wartime Environment, Jennifer A. Bollinger, Kellie L. Davila-Martinez
Theses and Dissertations
Lean Logistics was developed in response to budget cuts, force reductions, and a new political world order. The primary objective of Lean Logistics is to minimize the total system wide costs of the Air Force organization. Currently, the Air Force is seeking to cut costs by reducing inventories, improving repair processes, and employing faster transportation where possible. The purpose of this thesis is to determine if the Air Mobility Express (AMX) current sizing plan is capable of supporting the retrograde assets generated during the sustainment portion of a war. The Dyna-METRIC version 6.4 simulation program is employed to analyze the …
Crisis Airlift Management: Effective Scheduling, David C. Penny
Crisis Airlift Management: Effective Scheduling, David C. Penny
Theses and Dissertations
This is a report on the basis, data, findings, and models developed for US Transportation Command and Headquarters Air Mobility Command. Focusing on the dynamic scheduling problem that arises during management of airlift assets into space-constrained airfields during a crisis, this research explains the conditions surrounding this event, discusses several areas of potential cross-functional applications, presents analysis of current performance, and provides several modeling possibilities for schedule efficiency. Past research in the Flow Management Problem (an airline flow control issue) is extensive, but specific applications in crisis airlift are long in coming, primarily due to the complexity of the environment. …
Modeling Diminishing Marginal Returns: An Application To The Aircraft Availability Model, Wayne L. Zorn
Modeling Diminishing Marginal Returns: An Application To The Aircraft Availability Model, Wayne L. Zorn
Theses and Dissertations
The Aircraft Availability Model (AAM) provides the Air Force with a worldwide peacetime requirement for reparable spare parts. This research models AAM methodology as it relates to the concept of diminishing marginal returns in resource application. Three separate modeling techniques are investigated with the goal of reformulating the AAM as a mathematical programming model that provides a comparable solution and a capable tool for the conduct of sensitivity analysis. The general formulations presented here are continuous non-linear, continuous linear, and piecewise linear discrete/continuous models. Two formulations of the piecewise linear discrete/continuous model are presented. The piecewise linear model based on …
Requirement For C-130 Aircraft In The Intratheater Korean Scenario, Philip B. Oglesby
Requirement For C-130 Aircraft In The Intratheater Korean Scenario, Philip B. Oglesby
Theses and Dissertations
In an effort to provide a timely and reasonably accurate methodology for determining C-130 intratheater airlift requirements, this research concentrated on a rough-cut capacity approach using a straight forward linear programming spreadsheet model. To provide more detailed analysis, a more sophisticated linear program was investigated. Specifically, the spreadsheet model calculated the minimum number of C-130s required to carry required cargo, passenger, and aeromedical loads based on user-defined daily requirements. For a given scenario, inputs include the daily requirements and the expected capacity for C-130 aircraft, trucks, and 22-car trains. Included in the capacity inputs are the number of daily cycles …
