An Information Theoretic Investigation Of Complex Adaptive Supply Networks With Organizational Topologies, Joshua V. Rodewald

Theses and Dissertations

Supply networks exist throughout society in manufacturing and knowledge-intensive industries as well as many service industries. Organizations have been noted to behave as complex adaptive systems or information supply networks with both formal and informal structures. Thoroughly understanding supply network structure and behavior are critical to managing such organizations effectively, but their properties of complex adaptive systems make them more difficult to analyze and assess, forcing researchers to rely on unrealistic data or assumptions of behavior. This research proposes an information theoretic methodology to discover such complex network structures and dynamics while overcoming the difficulties historically associated with their study. …

The Influence Of Education And Experience Upon Contextual And Task Performance In Warehouse Operations, Allen R. Miller

Theses and Dissertations

Supply chain workers make observable, preventable errors while completing their assigned tasks in the shipping process. Previous research has indicated that individuals with a greater grasp of their work and better system knowledge are less likely to commit interpretation errors. We believe worker-performance may, likewise, be affected by an individuals knowledge of why and where they fit into a larger system defined as mission knowledge. To assess our research objectives, we conduct a controlled experiment with 100 workers in the Air Force supply career field to discern how mission clarity, that is, education, experience and subject characteristics affect pick and …

In 2007 and 2008 two major incidents occurred, a necessary to bring focus and priority back to the nuclear enterprise. Several reports were accomplished to identify the issues and recommendations. …

Applying Lean To The Ac-130 Maintenance Process For The Royal Saudi Air Force, Fisal A. Alzahrani

Theses and Dissertations

The ideas expressed in this research come from the researchers experiences working in the AC-130 maintenance squadron in the Royal Saudi Air Force. The AC-130 maintenance process is not currently being used as effectively as it could be to make AC-130 fully mission capable. That can be done by improving communication, reducing distances needed to move or transport anything during the maintenance process and by efficient use of the available qualified workforces, tools and equipment. Consideration is given to applying an existing management technique to the Royal Saudi Air Forces AC-130 Maintenance Squadrons. The selected technique is the Lean management …

Usaf Female Pilot Turnover Influence: A Delphi Study Of Work-Home Conflict, David C. Caswell

Theses and Dissertations

This study examined factors which influence the female pilot’s decision to stay or leave the Air Force. The concepts of turnover and Work-Home Conflict (WHC) were explored as a theoretical foundation. WHC describes the resultant clash as the work and home/family roles individuals attempt to balance compete for resources. This research used data from a Delphi study of 20 female active-duty U.S. Air Force pilots to provide insight into the turnover decision process of female pilots. This study concluded that WHC and family satisfaction variables should be included in future studies of a larger sample population. Additionally, the research provided …

We assess cost growth factors at four major reviews, Critical Design Review, First Flight, Development Test and Evaluation End, and Initial Operating Capability. The first portion of the analysis focuses on identifying cost growth factors and percent of total cost growth at the four program reviews. The second portion identifies predictors of cost …

Unmanned Aerial Vehicle (Uav) Operators’ Workload Reduction: The Effect Of 3d Audio On Operators’ Workload And Performance During Multi-Aircraft Control, Sungbin Kim

Theses and Dissertations

The importance and number of Unmanned Aerial Vehicle (UAV) operations are rapidly growing in both military and civilian applications. This growth has produced significant manpower issues, producing a desire that multiple aircraft are controlled by a single operator as opposed to the current model where one aircraft may require multiple operators. A potential issue is the need for an operator to monitor radio traffic for the call signs of multi-aircraft. An investigation of the use of 3D sound was undertaken to investigate whether an automatic parser, which preselected the spatial location of relevant versus irrelevant call signs, could aid UAV …

An Evaluation Of Forecasting Methods That Could Be Used In The Brazilian Air Force Uniform Distribution Process, Leandro Valviesse De Oliveira

Theses and Dissertations

Every year the Brazilian Air Force (BAF) spends the equivalent of approximately 15 million dollars for uniforms. These purchases come from a tight budget, are executed through public procurement processes, and are tied to Brazilian acquisition regulations, which are often very strict. For this reason, lead times are unpredictable. It can take anywhere from one month to a year to replenish an item. The purpose of this research is to analyze the forecasting process performed at a BAF military organization named Sub-directorate of Supply (SDS) with the intent of building an algorithm comprised of a selection of forecasting models in …

Factors Influencing Skill Retention In Multi-Skilled Air Force Aircraft Maintainers, Jessica A. Salgado

Theses and Dissertations

The 2013 National Defense Authorization Act allows the Air Force Air Logistics Complexes (ALCs) to promote workers proficient in more than one trade by one pay grade. Multi-skilling is the term used to describe workers trained in more than one job. The United States Air Force wants to utilize multi-skilling at these ALCS, but the effects of implementation are still unknown. This research focuses on the identification of skill retention influences to better understand this multi-skilling through the use of a human subjects experiment at two Air Force bases. We examine the retention of aircraft mechanics’ skill to evaluate the …

Simulation Modeling And Analysis Of Air Force Depot Engine Repair During Normal And Increased Operational Tempos, Changsung Kim

Theses and Dissertations

Maintaining an adequate level of aircraft availability through Agile Combat Support (ACS) is crucial for the Air Force to perform its mission. During normal day to day operations, demands for depot repair including spare parts and maintenance man-hours typically fall within a range supportable with current assets and capabilities. However, with increased flying operations during a conflict, demand at the depot level may likely exceed current capacity for timely support, resulting in backorders for spares and increased turnaround times. This thesis develops a discrete event simulation of the F-16 engine repair network to investigate the impact on engine availability (a …

Civil Engineer Company Grade Officer Training Needs Analysis For Contingency Operations, Brian S. Greszler

Theses and Dissertations

In terms of active duty personnel, the USAF is the smallest it has ever been since its creation in 1947. With fewer personnel to accomplish essential tasks, the training of Airmen is more important than ever. Outdated and irrelevant training can lead to gaps in the knowledge of trainees. The purpose of this research was to analyze the training needs of Civil Engineer (CE) Company Grade Officers (CGOs) in the contingency environment. This was done by first conducting a Job Analysis (JA). The JA resulted in a list of 36 critical tasks and 58 important Knowledge, Skills, and Abilities (KSAs). …

Earned Value Reporting On Agile Software Development Programs Within The Department Of Defense, Elizabeth G. Hodson

Theses and Dissertations

The correct measurement of earned value on agile software development programs has recently been identified as a concern by software developers implementing agile development methods. This research attempts to address the difficulties in reporting earned value on agile development programs, and the differences between the measures of completion in agile development versus earned value reporting. The major difference was identified to be in translating between the work originally planned and the work that was “recently” planned as part of the agile development process. This difference, if not transparent, leads to different measurements of earned value and inconsistent reports of a …

A Comparative Study Of Learning Curve Models And Factors In Defense Cost Estimating Based On Program Integration, Assembly, And Checkout, Brandon J. Johnson

Theses and Dissertations

The purpose of this research was to investigate the flattening effect at tail end of learning curves by identifying a more accurate learning curve model. The learning curve models accepted by DOD are Wright’s original learning curve theory and Crawford’s Unit Theory. The models were formulated in 1936 and 1944 respectively. This analysis compares the conventional models to contemporary learning curve models in order to determine if the current DOD methodology is outdated. The results are inconclusive as to if there is a more accurate model. The contemporary models are the DeJong and S-Curve and they both include an incompressibility …

Analysis Of Inpatient Hospital Staff Mental Workload By Means Of Discrete-Event Simulation, Erich W. Maxheimer

Theses and Dissertations

Many process improvement tools have been applied to the healthcare industry to improve safety and efficiency. However, nearly all of these tools have neglected to explicitly quantify mental workload of healthcare providers despite the consensus that it is related to human performance. This research uses the Improved Performance Research Integration Tool (IMPRINT), a discrete-event simulation (DES), to quantify mental workload. Specifically, this research examines staff members in an inpatient unit at the Wright-Patterson Medical Center to detect workload differences between staff, identify trends which lead to high workload demands, evaluate the influence of patient load on mental workload, and test …

Determining The Optimal Work Breakdown Structure For Government Acquisition Contracts, Brian J. Fitzpatrick

Theses and Dissertations

The optimal level of Government Contract Work Breakdown Structure (G-CWBS) reporting for the purposes of Earned Value Management was inspected. The G-Score Metric was proposed, which can quantitatively grade a G-CWBS, based on a new method of calculating an Estimate At Completion (EAC) cost for each reported element. A random program generator created in R replicated the characteristics of DOD program artifacts retrieved from the Cost Analysis Data Enterprise (CADE) system. The generated artifacts were validated as a population, however validation at the demographic combination level using an artificial neural network was inconclusive. Comparative WBS forms were created for a …
