Relating Initial Budget To Program Growth With Rayleigh And Weibull Models, Eric J. Unger
Relating Initial Budget To Program Growth With Rayleigh And Weibull Models, Eric J. Unger
Theses and Dissertations
Previous research on completed defense R&D shows that contract expenditures can be fit well with a Rayleigh model. With fixed outlay rates, as prescribed by the OSD comptroller, the budget profile must have most of the funds in the early years to produce Rayleigh-distributed expenditures. R&D programs with more delayed funding profiles may also produce expenditures that a Rayleigh model fits through schedule slips and cost overruns. This research tests how well the initial funding profile produces Rayleigh-distributed expenditures that can be related to the program's final cost overrun and schedule slips. Based only on the initial budget profile, we …
Revising R & D Program Budgets When Considering Funding Curtailment With A Weibull Model, Paul H. Porter
Revising R & D Program Budgets When Considering Funding Curtailment With A Weibull Model, Paul H. Porter
Theses and Dissertations
This research develops an analytical technique to estimate the impact of funding curtailment on an R&D program. The method quickly produces a revised budget by year for an on-going R&D program when funding in one year is reduced. We assume program requirements remain unchanged. The program duration may be unchanged or "stretched" to a later completion date. We use the Rayleigh and Weibull functions to model expenditure profiles, which forms basis of the analytical approach. Our proposed methodology accounts for budget outlay rates and inflation. We validate the proposed analytical technique using historical cost data from several programs.
Dollarizing Qualitative Discriminators Used In Best Value Source Selections, Jason R. Borchers
Dollarizing Qualitative Discriminators Used In Best Value Source Selections, Jason R. Borchers
Theses and Dissertations
With the decreasing budget that gets allocated to the Department of Defense each year, the government needs to be able to acquire more with less. This has a direct impact on how source selections are conducted. This research proposes a method using four different levels of cost that will provide the government with the best overall value in the conduction of source selections. This differs from previous source selections, because source selection teams, in general, only considered proposal price in their evaluation.
A Critical Analysis Of The Air Force's International Merchant Purchase Authorization Card (Impac) Program, Roy D. Thrailkill
A Critical Analysis Of The Air Force's International Merchant Purchase Authorization Card (Impac) Program, Roy D. Thrailkill
Theses and Dissertations
The United States Air Force (USAF) purchased over $ 1.3 billion worth of goods and services with the IMPAC in fiscal year (FY) 2000 alone. The proliferation of the IMPAC has changed the way organizations procure goods and services and empowered them with a tool to increase their procurement flexibility and responsiveness. These benefits have been accompanied by regulatory and procedural constraints that have presented challenges to key participants of this streamlined purchase process. This thesis addresses documented deviations of the IMPAC program's execution from its theoretical design. It describes the structure of the IMPAC program, analyzes the execution of …
Estimating C-17 Operating And Support Costs: Development Of A System Dynamics Model, Christopher D. Purvis
Estimating C-17 Operating And Support Costs: Development Of A System Dynamics Model, Christopher D. Purvis
Theses and Dissertations
This research provides justification for experimenting with system dynamics (SD) for performing Operation and Support Cost estimates. For the C-17 Globemaster III cargo aircraft, these costs could exceed $64 billion dollars. Also, many of our weapon systems are beginning to reach the end of their effective life span, and discussions about the impact of aging, on aircraft, has become a hot topic in the literature. System Dynamics is a modeling methodology developed in 1958, but never used extensively for cost estimating. SD offers unique capabilities to the cost estimator, including the ability to model causal relationships. This capability offers the …
