The Impact Of Changing The Size Of Aircraft Radar Displays On Visual Search In The Cockpit, Justin R. Marsh
The Impact Of Changing The Size Of Aircraft Radar Displays On Visual Search In The Cockpit, Justin R. Marsh
Theses and Dissertations
Advances in sensor technology have enabled our fighter aircraft to find, fix, track, target, engage (F2T2E) at greater distances, providing the operator with more data within the battlefield. Modern aircraft are designed with larger displays while our legacy aircraft are being retrofitted with larger cockpit displays to enable display of the increased data. While this modification has been shown to enable improvements in human performance of many cockpit tasks, this effect is often not measured nor fully understood at a more generalizable level. This research outlines an approach to comparing human performance across two display sizes in future F-16 cockpits. …
A Comparative Study Of Learning Curve Models And Factors In Defense Cost Estimating Based On Program Integration, Assembly, And Checkout, Brandon J. Johnson
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the conventional models to contemporary learning curve models in order to determine if the current DOD methodology is outdated.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 …
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 Inventory And Safety Stock Analysis Of Air Force Medical Service Pharmaceuticals, Blake Smith
An Inventory And Safety Stock Analysis Of Air Force Medical Service Pharmaceuticals, Blake Smith
Theses and Dissertations
A significant challenge facing the Air Force Medical Service (AFMS) Military Treatment Facilities (MTFs) is the perishability costs associated with its pharmaceutical stock. During a two year time period, the AFMS returned expired or nearly expired pharmaceuticals valued at over $23,000,000. In response to the waste represented by pharmaceutical perishability cost, this thesis analyzes the historical inventory management decisions of 173 MTF/pharmaceutical combinations and proposes an alternative inventory control policy to reduce perishability costs. Based on the critical nature of pharmaceuticals and importance of generating high patient satisfaction, the proposed alternative inventory control system was required to be cognizant of …
The Effect Of Stages And Levels Of Automation And Reliability On Workload And Performance For Remotely Piloted Aircraft Operations, Stephen P. Katrein
The Effect Of Stages And Levels Of Automation And Reliability On Workload And Performance For Remotely Piloted Aircraft Operations, Stephen P. Katrein
Theses and Dissertations
This thesis investigates incorporating different stages and levels of automation with varying degrees of reliability into a remotely piloted aircraft (RPA) surveillance task in order to determine how automation implementation and reliability affect operator workload and system performance. The study uses IMPRINT discrete event simulation to evaluate three levels of reliability in twelve different baseline automation implementations within a remotely piloted vehicle task. Three stages and four levels are modeled, for a total of twelve combinations, along with a baseline task with no automation. The stages modeled are the information acquisition stage, the decision and action selection stage, and the …
The Effects Of Opinion Leaders And Change Messages On Organization Member Change Attitudes: A Field Experiment, Ryan L. Leblanc
The Effects Of Opinion Leaders And Change Messages On Organization Member Change Attitudes: A Field Experiment, Ryan L. Leblanc
Theses and Dissertations
The extent to which three change introduction strategies (i.e., opinion leadership, edict, and change message) influenced readiness for change were tested at four locations as part of a quasi-field experiment with three groups receiving an enriched change message and one control group. Readiness was measured before and after change implementation where it was hypothesized that change readiness would be most improved within the groups that heard the most persuasive and rich change messages. These hypotheses were not supported and data indicated that the differing treatments were never received by the majority of the change recipients, rendering the results of the …
