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 …
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 …
