Analysis And Forecasting Of U.S. Navy Operating And Support (O&S) Costs For Rotary Aircraft, Christopher J. Wilkes Mar 2004

Analysis And Forecasting Of U.S. Navy Operating And Support (O&S) Costs For Rotary Aircraft, Christopher J. Wilkes

Theses and Dissertations

This research explores forecasting techniques to estimate the Cost per Flying Hour (CPFH) for Navy rotary aircraft. Three separate forecasting techniques were evaluated to better predict the CPFH for better estimating and budgeting by the U.S. Navy. The process begins by empirically analyzing Operating & Support cost categories for each helicopter. Trends were examined in CPFH. For forecasting purposes, actual CPFH figures were compiled from 1997 to 2003 for the CH-46D, the CH-53D, the MH-53E, the SH-60F, the UH-1N, and the UH-3H helicopters. The forecasting techniques explored were the 3-year moving average, the single exponential smoothing method, and Holt's linear …


Estimating The Operating And Support Cost Difference Among Tuaf C-130, C-130b And Usaf C-130j Aircraft, Kubilay Kosucu Mar 2002

Estimating The Operating And Support Cost Difference Among Tuaf C-130, C-130b And Usaf C-130j Aircraft, Kubilay Kosucu

In an era of decreasing defense budgets in Korea, the Korean Air Force Transportation Department has suffered from an insufficient vehicles procurement budget, resulting in fewer vehicles of increasing age, as well as decreasing military morale. For these reasons, the Korean Air Force Transportation Department needs a breakthrough to retain the transportation ability to support the field of operation in an effective and economic way. However, the Korea Air Force Transportation Department has only one method for procuring general-purpose vehicles, which is purchasing. Thus, the comparative analysis of leasing versus buying vehicle study started from the recognition of this situation …


A Life Cycle Cost Analysis Of The Proposed Replacement Of Pope Air Force Base's C-130e Fleet Using A Fleet Replacement Model, Lance R. French Mar 2002

A Life Cycle Cost Analysis Of The Proposed Replacement Of Pope Air Force Base's C-130e Fleet Using A Fleet Replacement Model, Lance R. French

Theses and Dissertations

The 43rd Airlift Wing at Pope AFB, NC, possesses 33 E-model C-130 aircraft. The airplanes range in age from 30-36 years old. Current plans call for replacing Pope's aging fleet of tactical airlifters with new C-130J model planes in FY11. There are two replacement alternatives proposed in this research. The first is to calls for replacing the C-130Es with C-130Js now. The second option is upgrade the C-130Es to C-130Xs and replace them in 10 years with the C-130J. The results indicate that the least cost solution is to upgrade Pope's fleet of C-130Es to C-130Xs now. However, after conducting …


Life Cycle Costs Of Alternatives For F-16 Printed Circuit Board Diagnosis Equipment, Kent R. Montgomery, Clifford B. Thorstenson Dec 1994

Life Cycle Costs Of Alternatives For F-16 Printed Circuit Board Diagnosis Equipment, Kent R. Montgomery, Clifford B. Thorstenson

Theses and Dissertations

This study analyzes two alternatives for printed circuit board (PCB) diagnosis for the F-16 depot PCB repair shop from a life cycle cost (LCC) perspective. Alternative 1 assumes the use of the current F-16 automatic test equipment (ATE) while Alternative 2 augments the current ATE with infrared imaging test equipment. Infrared imaging is a developed technology that is currently available to the Air Force in a commercial-off-the-shelf (COTS) form. Using the Cost Analysis and Strategy Assessment (CASA) Life Cycle Cost (LCC) Model and data from the DL41 database on F-16 PCBs this study determined that over the current expected life …
