Economic Analysis For An F-22 Organic Vs. Contractor Aircraft Battle Damage Repair Ownership Decision, John A. Kitchens
Economic Analysis For An F-22 Organic Vs. Contractor Aircraft Battle Damage Repair Ownership Decision, John A. Kitchens
Theses and Dissertations
The purpose of this study was to evaluate whether Contractor Logistics Support (CLS) is a viable alternative to Combat Logistics Support Squadrons (CLSSs) for providing F-22 Aircraft Battle Damage Repair (ABDR). Legalities, practicalities, and cost-effectiveness were key ownership concerns. United States Code, Office of Management and Budget, Department of Defense (DoD), and United States Air Force (USAF) requirements were reviewed to address legal and policy issues and whether F-22 ABDR is military essential. The Army's Logistics Civil Augmentation Program (LOCCAP) award fee history was used to assess the potential performance of F-22 ABDR CLS personnel. F-117 ABDR team requirements and …
Comparison Of Effects Of Change From 8 To 12 Hour Shifts On Air Force Aircraft Maintenance Workers, Daniel W. Overland
Comparison Of Effects Of Change From 8 To 12 Hour Shifts On Air Force Aircraft Maintenance Workers, Daniel W. Overland
Theses and Dissertations
This study examined the effects of converting from an 8 hour shift system to a 12 hour system on aircraft maintenance personnel. The squadron had converted its 24 hour operations from an 8 hour shift schedule to a 12 hour shift schedule in stages, changing one group first and then another. A smaller third group of workers remained on 8 hour shifts. Individual differences in job related outcomes and situational constraints were measured for all three groups. Results showed that changing from 8 to 12 hour shifts affected worker well-being and morale, as indicated by an increase in hospital visits …
Estimating Kc-137 Aircraft Ownership Costs In The Brazilian Air Force, Ulisses O. Bonasser
Estimating Kc-137 Aircraft Ownership Costs In The Brazilian Air Force, Ulisses O. Bonasser
Theses and Dissertations
This research addresses the estimation of operation and support (O&S) costs of the Brazilian Air Force KC-137 aircraft. BAF lacks an established set of procedures for computing ownership costs of such aircraft, which prejudices the elaboration of cost-benefit analysis and allocation of budget resources. The purpose of the study is to develop an O&S cost breakdown structure and a set of cost estimating equations that will be used to estimate the ownership costs of the KC-137 aircraft during their expected service life.
Turkish Air Mobility Modeling, Huseyin Topcuoglu
Turkish Air Mobility Modeling, Huseyin Topcuoglu
Theses and Dissertations
The aim of this research is to provide a tactical mobility model which is user friendly and flexible so the user is able to change the inputs, and evaluate the situation with the projected data for an operational plan. Thus, the users can analyze their system by using the model to see whether or not mobility requirements can be met within a definite time frame, and how long it takes to satisfy the requirements. Generalized Air Mobility Model (GAMM) was chosen to model TAMC's airlift system and has been found suitable for application to TUAF mobility problems. The software enables …
Determining The Economic Plausibility Of Dual Manifesting Reusable Launch Vehicles And Reusable Orbital Transfer Vehicles For The Replenishment Of Military Satellites, Crystal L. Evans
Theses and Dissertations
Currently, the Air Force launches military satellites on expendable launch vehicles to low earth orbit (LEO), and with the use of a chemical upper stage or an apogee kick motor, moves the satellite to a higher orbit. This launch procedure is extremely costly because it requires additional launch preparations, technology considerations, equipment, and fuel. Also, the additional mass of the chemical upper stage causes a larger, and thus more expensive, launch vehicle to be required. An economical alternative is to utilize reusable launch vehicles (RLVs) and reusable orbital launch vehicles (ROTVs). This concept could possibly achieve even greater savings if …
Analysis Of Aircraft Sortie Generation With Concurrent Maintenance And General Service Times, Daniel V. Hackman
Analysis Of Aircraft Sortie Generation With Concurrent Maintenance And General Service Times, Daniel V. Hackman
Theses and Dissertations
The primary objective of this study was to develop an analytical methodology for evaluating an aircraft sortie generation process. The process is modeled as a closed network of general service queues with a fork join node to model concurrent servicing. The model uses the Mean Value Analysis (MVA) algorithm and general queueing network analysis by decomposition to approximate network performance measures including resource utilization and the overall sortie generation rate. The results of the study show that the analytical approximation's accuracy decreases as server utilization increases. However, when server utilization is kept in realistic ranges, the approximation is very accurate. …
