Available in PDF, EPUB and Kindle. Book excerpt: Why have the costs of acquiring space systems been so high? What are the sources of the problems? To answer these questions, RAND researchers examined the sources of cost growth of Air Force space systems and undertook an extensive study of two space systems--the Space Based Infrared System-High (SBIRS) and the Global Positioning System (GPS)--including an evaluation of their sources of cost growth, an assessment of their approaches to technical risk assessment, and an examination of their acquisition policy adaptations and industrial base environments. The researchers recommend independent program assessment for space systems that emphasizes technical and program factors, and a modified organizational structure that maintains cost analyst independence. They also summarize the cost estimating best practices of several other government organizations.

Available in PDF, EPUB and Kindle. Book excerpt: To use public funds effectively, the gov¿t. must meet the demands of today's changing world by employing effective mgmt. practices and processes, including the measurement of gov¿t. program performance. Legislators, gov¿t. officials, and the public want to know whether gov¿t. programs are achieving their goals and what their costs are. To make those evaluations, reliable cost information is required and fed. standards have been issued for the cost accounting that is needed to prepare that information. This Cost Guide has been developed in order to establish a consistent methodology that is based on best practices and that can be used across the fed. gov¿t. for developing, managing, and evaluating capital program cost estimates.

Available in PDF, EPUB and Kindle. Book excerpt: In response to historically high cost growth in the acquisition of space systems, the Under Secretary of the Air Force, in accordance with National Security Space (NSS) Acquisition Policy, directed the Air Force acquisition community to support the development of independent, accurate, and timely cost analyses to make the acquisition of NSS systems more realistic in terms of estimated costs. In turn, the former commander of Air Force Space Command (AFSPC), Gen Lance W. Lord, and the former commander of the Air Force Space and Missile Systems Center (SMC), Lt Gen Michael Hamel, asked RAND Project AIR FORCE to assess cost-estimating requirements and capabilities of SMC cost-estimating organizations as well as their resources, tools, methods and processes and to recommend an enhanced approach to cost analysis aimed at improving cost-estimating for space systems and increasing the understanding of factors that influence their cost. The study was sponsored by the former commander of SMC, General Hamel. The project technical monitor was Col Delane Aguilar, SMC/FMC. The research was conducted within the Resource Management Program of RAND Project AIR FORCE as part of a multiyear study entitled Air Force Space Systems Costs. The initial data collection was completed in May of 2006 and the final update was provided in February of 2007, with frequent updates in between. The final briefing was presented to General Hamel on March 13, 2007, and to Gen Kevin P. Chilton, the former commander of Air Force Space Command, on March 21, 2007. This monograph should interest government personnel involved in cost estimation and acquisition of defense systems, the military space acquisition communities, and those concerned with current and future acquisition policies.

Download or read book Functional Cost Estimating Relationships for Spacecraft written by and published by . This book was released on 1996 with total page 82 pages. Available in PDF, EPUB and Kindle. 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.

This book was released on 1967 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Economic and cost effectiveness analyses of proposed system concepts have become vital requirements in virtually all U.S. Air Force Space Systems Division studies. Since development of a space system is extremely costly, lead time is lengthy, and budget limitations are severe, there is a clear need to forecast the total systems cost and effectiveness of a proposed new system as early in the planning cycle as possible. This report presents highlights of the significant aspects of technical direction efforts in systems cost and cost effectiveness analyses. Major objectives of this effort are to ensure that the industry contractor: (a) Performs a total system cost analysis of sufficient depth and validity to permit analysis and evaluation; (b) Identifies those operational design and hardware concepts which will provide the greatest savings in total systems cost; (c) Properly validates those significant concepts and cost relationships which will lead to the selection of an optimum configuration. Recommendations on the approach and techniques to fulfill these objectives are provided. The uses and limitations of industry cost models, cost estimating relationships, and other estimating methods are discussed. Common pit-falls in system cost analysis are illustrated to indicate the guidance necessary.

This book was released on 2018-08-16 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: NASA is responsible for developing much of the nation's future space technology. Cost estimates for new programs are required early in the planning process so that decisions can be made accurately. Because of the long lead times required to develop space hardware, the cost estimates are frequently required 10 to 15 years before the program delivers hardware. The system design in conceptual phases of a program is usually only vaguely defined and the technology used is so often state-of-the-art or beyond. These factors combine to make cost estimating for conceptual programs very challenging. This paper describes an effort to develop parametric cost estimating methods for space systems in the conceptual design phase. The approach is to identify variables that drive cost such as weight, quantity, development culture, design inheritance and time. The nature of the relationships between the driver variables and cost will be discussed. In particular, the relationship between weight and cost will be examined in detail. A theoretical model of cost will be developed and tested statistically against a historical database of major research and development projects. Cyr, Kelley Unspecified Center ...

Book excerpt: The Reliability and Maintainability Analysis Tool (RMAT) provides NASA the capability to estimate reliability and maintainability (R&M) parameters and operational support requirements for proposed space vehicles based upon relationships established from both aircraft and Shuttle R&M data. RMAT has matured both in its underlying database and in its level of sophistication in extrapolating this historical data to satisfy proposed mission requirements, maintenance concepts and policies, and type of vehicle (i.e. ranging from aircraft like to shuttle like). However, a companion analyses tool, the Logistics Cost Model (LCM) has not reached the same level of maturity as RMAT due, in large part, to nonexistent or outdated cost estimating relationships and underlying cost databases, and it's almost exclusive dependence on Shuttle operations and logistics cost input parameters. As a result, the full capability of the RMAT/LCM suite of analysis tools to take a conceptual vehicle and derive its operations and support requirements along with the resulting operating and support costs has not been realized.Ebeling, CharlesLangley Research CenterCOST ANALYSIS; COST ESTIMATES; MATHEMATICAL MODELS; RELIABILITY ANALYSIS; MAINTAINABILITY; MISSION PLANNING; OPERATING COSTS; POLICIES; SPACE TRANSPORTATION SYSTEM FLIGHTS; SUPPORT SYSTEMS

Available in PDF, EPUB and Kindle. Book excerpt: Annotation "Design Methodologies for Space Transportation Systems is a sequel to the author's earlier text, "Space Transportation: A Systems Approach to Analysis and Design. Both texts represent the most comprehensive exposition of the existing knowledge and practice in the design and project management of space transportation systems, and they reflect a wealth of experience by the author with the design and management of space systems. The text discusses new conceptual changes in the design philosophy away from multistage expendable vehicles to winged, reusable launch vehicles and presents an overview of the systems engineering and vehicle design process as well as systems trades and analysis. Individual chapters are devoted to specific disciplines such as aerodynamics, aerothermal analysis, structures, materials, propulsion, flight mechanics and trajectories, avionics and computers, and control systems. The final chapters deal with human factors, payload, launch and mission operations, safety, and mission assurance. The two texts by the author provide a valuable source of information for the space transportation community of designers, operators, and managers. A companion CD-ROM succinctly packages some oversized figures and tables, resources for systems engineering and launch ranges, and a compendium of software programs. The computer programs include the USAF AIRPLANE AND MISSILE DATCOM CODES (with extensive documentation); COSTMODL for software costing; OPGUID launch vehicle trajectory generator; SUPERFLO-a series of 11 programs intended for solving compressible flow problems in ducts and pipes found in industrial facilities; and a wealth of Microsoft Excel spreadsheet programs covering thedisciplines of statistics, vehicle trajectories, propulsion performance, math utilities,
Download or read book Systems Cost Engineering written by Dale Shermon and published by Routledge. This book was released on 2017-03-02 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parametric cost estimating models are flexible tools which bring engineering, scientific and mathematical rigour to cost and schedule estimating, but great tools alone will not keep programs affordable. Tools must be applied as part of a credible process if estimates and analyses are to be accepted. Complex major projects involving engineering, hardware, software, service and IT, all suffer from two basic problems: the project sponsors often struggle to specify the project effectively, and project managers find themselves wrestling with unpredicted cost or schedule overruns. Everyone wants to be successful with the tools and solutions they use, so this book is a comprehensive collection of methods with proven success. The applications described by Dale Shermon and his co-authors have evolved over 30 years of cost engineering experience during which time they have been matured by the parametric community. Each chapter explores a different application of parametrics, based on real-life case examples, providing you with a detailed guide to the rationale and value of cost engineering in a different industry or program context. Systems Cost Engineering will help cost engineers, project and program directors, and the champions that support them, to understand and apply parametrics to ensure that their programs: * offer a credible analysis of alternative cost options * are never initiated with insufficient funding because of inaccurate estimates of cost or quantification of risks * are never diverted from their objective because of a lack of credible cost management * share and communicate knowledge of realistic and dynamic cost and productivity metrics amongst the program team * are never derailed by surprise cost overruns or schedule delays The information in this book will give projects sponsors and bid managers confidence in the business case that they are developing and enable them to communicate a clear and transparent picture of the risks, opportunities and benefits to stakeholders and project owners.
