Calibration And Validation Of The Cocomo Ii.1997.0 Cost/Schedule Estimating Model To The Space And Missile Systems Center Database, Wayne A. Bernheisel
Calibration And Validation Of The Cocomo Ii.1997.0 Cost/Schedule Estimating Model To The Space And Missile Systems Center Database, Wayne A. Bernheisel
Theses and Dissertations
The goal of this study was to determine the accuracy of COCOMO II.1997.0, a software cost and schedule estimating model, using Magnitude of Relative Error, Mean Magnitude of Relative Error, Relative Root Mean Square, and a 25 percent Prediction Level. Effort estimates were completed using the model in default and in calibrated mode. Calibration was accomplished by dividing four stratified data sets into two random validation and calibration data sets using five times resampling. The accuracy results were poor; the best having an accuracy of only .3332 within 40 percent of the time in calibrated mode. It was found that …
Calibration And Validation Of The Sage Software Cost/Schedule Estimating System To United States Air Force Databases, David B. Marzo
Calibration And Validation Of The Sage Software Cost/Schedule Estimating System To United States Air Force Databases, David B. Marzo
Theses and Dissertations
This research entailed calibration and validation of the SAGE Software Cost/Schedule Estimating System, Version 1.7 as a means to improve estimating accuracy for DoD software-intensive systems, and thereby introduce stability into software system development. SAGE calibration consisted of using historical data from completed projects at the Space and Missile Systems Center (SMC) and the Electronic Systems Center (ESC) to derive average performance factors (i.e., calibration factors) for pre-defined categories of projects. A project was categorized for calibration by either its primary application or by the contractor that developed it. The intent was to determine the more appropriate categorization for calibration. …
A Study Of Historical Inflation Forecasts Used In The Department Of Defense Future Years Defense Program, Mark S. Sweitzer
A Study Of Historical Inflation Forecasts Used In The Department Of Defense Future Years Defense Program, Mark S. Sweitzer
Theses and Dissertations
This thesis explores historical inflation forecasts used in the Department of Defense (DoD) Future Years Defense Program. The study examines historical DoD forecasts against experienced inflation as measured by the Gross National Product and Gross Domestic Product implicit price deflator (GNP/GDP IPD) from 1979 to 1996. This study also compares the accuracy of DoD forecasts with those made by the Congressional Budget Office (CBO) and Data Resources, Incorporated (DRI). The results regarding the performance of historical DoD inflation forecasts are mixed. Upon examining budget through five year GNP/GDP IPD forecast spans, DoD short-term results do not indicate a downward bias …
Tracking Overhead Orta Costs In Technology Transfer Activities, Thomas S. Van Egeren
Tracking Overhead Orta Costs In Technology Transfer Activities, Thomas S. Van Egeren
Theses and Dissertations
An ever shrinking Research and Development (R&D) budget, coupled with a widespread perception that the nation is not realizing an adequate return from its substantial investment in the federal laboratory system, has paved the way for an increase in the transfer of technology from the federal laboratories to the private sector. The objective of this research is to determine the indirect cost of performing technology transfer by identifying the resources consumed by several key Office of Research and Technology Applications (ORTA) organizations and the activities performed within these organizations. It was hypothesized that the ORTA organizations, which are considered indirect …
A Comparative Study And Estimation Of The Life-Cycle Cost Impact Of Application Of Real-Time Non-Intrusive (Rtni) Monitoring Technology To Real-Time Embedded Systems, Michael D. Lewis
Theses and Dissertations
The use of real time non-intrusive (RTNI) monitoring has had an impact on life cycle costs of existing programs through a reduction in debug time. Other areas in which RTNI monitoring can provide potential benefits to future programs are through the use of increased dynamic testing and the sharing of testing time among more engineers. There are a number of areas in which software life cycle costs are impacted by various cost drivers. To determine which areas were affected by the use of RTNI monitoring, a panel of expert users of RTNI monitoring was created using a form of the …
