Forecasting Research & Development Program Budgets Using The Weibull Model, Thomas W. Brown
Forecasting Research & Development Program Budgets Using The Weibull Model, Thomas W. Brown
Theses and Dissertations
Norden (1970) uses the Rayleigh, which is a degenerative of the Weibull, to model manpower on research and development (R&D) programs. Several research efforts extend his work including Lee, Hogue, and Gallagher (1997) who build R&D program budgets based on Rayleigh expenditures. We demonstrate the theoretical limitations to the Rayleigh model and present the Weibull model, which mitigates those limitations. Using 102 completed R&D defense programs, we develop regression models to predict the requisite shape and scale parameters to forecast Weibull-based budgets. Using the remaining 26 completed R&D programs to validate the robustness of our regression models, we show that …
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
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 …
