Williams and published by . This book was released on 1993 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this thesis is to develop estimating relationships for missile Engineering and Manufacturing Development (EMD) costs and warship fuel consumption to aid the Naval Center for Cost Analysis (NCA) in performing independent cost estimates for new weapons programs. Standard factors, which represent the percent that each cost element is typically allocated from the program's total funding, are currently used to predict whether missile EMD costs are roughly right. For fuel consumption, estimating relationships have only been developed for existing individual ship types. None have been developed which use pooled ship types to estimate fuel consumption of new ship types. Regression analysis was used to develop estimating relationships based on physical and technical characteristics. The cost estimating relationships (CERs) developed to predict missile EMD costs explained only about 34 percent of the variance. Due to the low explanatory power, no significant physical or technical factors could be determined. Even though the results are not statistically significant, the associated coefficients of variation are lower than the standard factor coefficients of variation. An estimating relationship with high explanatory power was developed to predict fuel consumption for new warships. Three significant physical and performance factors were determined: steaming hours, age and full load displacement. For new ship types, steaming hours and full load displacement are the significant factors.

Available in PDF, EPUB and Kindle. Book excerpt: This analysis uses data from Selected Acquisition Reports to determine the causes of cost growth in 35 mature major defense acquisition programs. Four major sources of growth are identified: (1) errors in estimation and scheduling, (2) decisions by the government, (3) financial matters, and (4) miscellaneous. The analysis shows that more than two-thirds of cost growth (measured as simple averages) is caused by decisions, most of which involve quantity changes, requirements growth, and schedule changes.

Download or read book Is Weapon System Cost Growth Increasing written by Obaid Younossi and published by Rand Corporation. This book was released on 2007 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent decades, there have been numerous attempts to rein in the cost growth of U.S. Department of Defense (DoD) acquisition programs. Cost growth is the ratio of the cost estimate reported in a program's final Selected Acquisition Report (SAR) and the cost-estimate baseline reported in a prior SAR issued at a particular milestone. Drawing on prior RAND research, new analyses of completed and ongoing weapon system programs, and data drawn from SARs, this study addresses the following questions: What is the cost growth of DoD weapon systems? What has been the trend of cost growth over the past three decades? To address the magnitude of cost growth, it examines cost growth in completed programs; to evaluate the cost growth trend over time, it provides additional analysis of a selection of ongoing programs. This sample of ongoing programs permits a look at growth trends in the more recent past. Changes in the mix of system types over time and dollar-weighted analysis were also considered because earlier studies have suggested that cost growth varies by program type and the cost of the program. The findings suggest that development cost growth over the past three decades has remained high and without any significant improvement.

Available in PDF, EPUB and Kindle. Book excerpt: Systems engineering and program management (SE/PM) constitute a large portion of the acquisition cost of military aircraft and guided weapons systems. The goal of this study was the development of a set of cost-estimating relationships that can be used to estimate the SE/PM cost element for development and production of aircraft and weapons programs. The authors canvassed government and industry personnel to learn about current techniques for estimating SE/PM costs, and they collected historical data from several aircraft and weapons programs to investigate trends in SE/PM costs over time and to generate methods that cost analysts can use early in the life cycle of a program when little cost information is available. The authors also investigated the effects on SE/PM costs from acquisition reform, including the reduction in the number of military specifications and standards, the use of integrated product and process teams, and the trend toward "evolutionary acquisition." This product is part of the RAND Corporation monograph series. RAND monographs present major research findings that address the challenges facing the public and private sectors.

This book was released on 1975 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study addresses the problem of estimating the development, procurement, and installation costs of surface ship electronic warfare equipment of the future. The Cost Estimating Relationships (CERs) were developed using the following factors: year of development, weight, volume, sensitivity, power output, gain, complexity and dummy variables for active equipment, equipment designed for large ships and one for those designed for small ships. Cost estimates are made for three systems presently under development by Raytheon Company and Hughes Aircraft Company under a design-to-price program.

Book excerpt: The costs to acquire space-based missile defense systems are often reviewed by DoD. Issues are raised concerning the cost models used to generate cost estimates for space-based missile defense systems. The Ballistic Missile Defense Organization questions the use of traditional weight-based spacecraft cost models developed by the Air Force Space and Missile Systems Center. The concern is motivated by changes in satellite designs of future systems where smaller but more capable spacecraft are being built. Using weight-based cost models yields lower cost estimates, although the spacecraft are more capable. IDA developed spacecraft functional (engineering and manufacturing) cost-estimating relationships (CERs) at the spacecraft subsystem level using performance and physical characteristics that are not primarily weight-based. We developed nonrecurring (design, development, and test) and recurring (production) CERs for the spacecraft bus, including ground support equipment, and for communications payloads. The CERs show that programmatic aspects, which reflect the requirements and acquisition environments that the satellites were acquired under, have considerable influence on satellite costs.
Download or read book Pitfalls in Calculating Cost Growth from Selected Acquisition Reports written by Paul G. Hough and published by . This book was released on 1992 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cost growth is a highly visible phenomenon in the procurement of major weapon systems. In general, cost growth is the ratio of a weapon system's current estimate of cost to that of some earlier estimate. Thus, even given the same current estimate, different measures of cost growth are possible, depending on which prior estimate is selected as the baseline. Most studies of cost growth, however, select the cost estimate made at the time of program entry into full-scale development (the development estimate) as the baseline. Both the current estimate and the development estimate are normally taken from the Selected Acquisition Report (SAR), a legally mandated summary report on the status of major acquisition programs. This Note identifies and explains the type of cost data found in the SAR and reviews the history of the SAR with respect to cost reporting. In spite of changes that have improved the quality and comprehensiveness of the data in the SAR, it still presents difficulties for measuring cost growth. Among the most notable problems are failure of some programs to use a consistent baseline cost estimate, exclusion of some significant elements of cost, exclusion of certain classes of major programs, and constantly changing preparation guidelines. Nevertheless, the author concludes that SAR data are suitable for identifying broad-based trends and temporal patterns across a range of programs.
Download or read book Cost Estimating Relationships for U S Navy Ships written by W. J. E. Shafer and published by . This book was released on 1983 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cost estimating relationships based on the observed (reported) cost and weight (full load displacement) of U.S. Navy ships are derived for the purpose of applying these cost estimating relationships to ships in the fleets of both the U.S. and USSR. This application results in broad, general comparisons that, in the aggregate, provide useful trend comparisons. These cost estimating relationships produce varying results on a class basis, but within each group or category of ships the class overestimates tend to be offset by class underestimates to yield a relatively small category error. This paper updates major portions of IDA Paper P-1530, Simple Relationships for Estimating Procurement Cost of U.S. Navy Ship Categories, dated March 1982.
