Book excerpt: In recent years, a number of attempts have been made to estimate the cost of future weapon systems toward the goal of optimizing acquisition policy. This report focuses specifically on the effects of material mix, manufacturing techniques, and geometric part complexity on the cost of military airframes. It begins by offering background information on those materials that are most critical to airframe manufacture and on the relative advantages of both traditional and evolving part fabrication techniques. It then proceeds to a quantitative analysis of the cost implications of various materials and manufacturing techniques on airframe production, drawing both from an industry survey and from analysis of industry data. The data thus derived are then integrated with those of a comprehensive historical database. The report concludes that composites, while offering a number of advantages over metals in airframe manufacture, are generally associated with higher costs across a range of categories. At the same time, it concludes that while new manufacturing technologies hold the potential to diminish airframe manufacturing costs, the increased airframe complexity of future fighter aircraft may well offset this advantage. The report recommends that cost analysts remain abreast of changes in industry practice so that they may more accurately gauge the potential effects of such changes on future airframe costs.

Available in PDF, EPUB and Kindle. Book excerpt: Good cost estimates can make important contributions to effective acquisition policy. RAND has a long history of producing cost-estimating methodologies. Two of its more recent studies are Hess and Romanoff (1987) and Resetar, Rogers, and Hess (1991). This report both updates and extends these earlier studies, focusing on the effects of material mix, manufacturing technique, and part geometric complexity on cost. We collected two types of information on these effects. First, we surveyed the military airframe industry for estimates of how aircraft production costs vary with airframe structure material mix. Second, we analyzed a large set of actual part data from recent aircraft manufacturing efforts that we collected from industry. We also estimated a set of airframe relationships (CERs) for labor hours based on MACDAR, a historical airframe database. We then integrated the effects of material mix into these estimates.

Book Synopsis Historical Cost Growth of Completed Weapon System Programs by : Mark V. Arena
Download or read book Historical Cost Growth of Completed Weapon System Programs written by Mark V. Arena and published by Rand Corporation. This book was released on 2006 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is one of a series from a RAND Project AIR FORCE project, "The Cost of Future Military Aircraft: Historical Cost Estimating Relationships and Cost Reduction Initiatives." The purpose of the project is to improve the tools used to estimate the costs of future weapon systems. It focuses on how recent technical, management, and government policy changes affect cost. This report focuses on the accuracy of cost estimates. For our analysis, we used a very specific sample of Selected Acquisition Report (SAR) data, namely only programs that are complete or are nearly so. The analysis indicates a systematic bias toward underestimating the costs and substantial uncertainty in estimating the final cost of a weapon system. In contrast to the previous literature, the cost growth was higher than previously observed. We also found few correlations with cost growth, but observed that programs with longer duration had greater cost growth and electronics programs tended to have lower cost growth. Although there were some differences in the mean cost growth factors among the military departments, the differences were not statistically significant. While newer programs appear to have lower cost growth, this trend appears to be due to factors other than acquisition policies.

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.

Book Synopsis Systems Engineering and Program Management by : David E. Stem
Download or read book Systems Engineering and Program Management written by David E. Stem and published by Rand Corporation. This book was released on 2006 with total page 211 pages. 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. All RAND monographs undergo rigorous peer review to ensure high standards for research quality and objectivity. Book jacket.

Book Synopsis Is Weapon System Cost Growth Increasing? by : Obaid Younossi
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.
Download or read book Lavi written by John W. Golan and published by U of Nebraska Press. This book was released on 2016-01-01 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Lavi fighter program, the largest weapons-development effort ever undertaken by the State of Israel, envisioned a new generation of high-performance aircraft. In a controversial strategy, Israel Aircraft Industries intended to develop and manufacture the fighters in Israel with American financial support. The sophisticated planes, developed in the mid-1980s, were unique in design and intended to make up the majority of the Israeli air force. Though considerable prestige and money were at stake, developmental costs increased and doubts arose as to whether the Lavi could indeed be the warplane it was meant to be. Eventually the program became a microcosm for the ambitions, fears, and internal divisions that shaped both the U.S.-Israeli relationship and Israeli society itself. But the fighter never made it to operational service, and until now, the full breadth and significance of the Lavi story have never been examined and presented. Lavi: The United States, Israel, and a Controversial Fighter Jet traces the evolution of the Lavi fighter from its genesis in the 1970s to its scrapping in August 1987. John W. Golan examines the roles of Israeli military icons and political leaders such as Ezer Weizman, Ariel Sharon, Menachem Begin, and Yitzhak Rabin in the program and in relation to their counterparts in the United States. On the American side, Golan traces the evolution of government policy toward the program, detailing the complex picture of the U.S. foreign policy apparatus and of U.S.-Israeli relations in general—from President Reagan’s public endorsement of the program on the White House lawn to Defense Secretary Caspar Weinberger’s unremitting attempts to cancel it in succeeding years.
Book Synopsis Machining of Light Alloys by : Diego Carou
Download or read book Machining of Light Alloys written by Diego Carou and published by CRC Press. This book was released on 2018-08-06 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aluminium, magnesium and titanium are alloys of special interest for engineering applications in a wide range of sectors such as aeronautics, automotive and medical. Their low density, along with sufficient mechanical properties, makes them especially adequate for sectors such as transportation allowing diminishing weight less fuel consumption and emissions to the atmosphere. Nowadays, machining is still one the most important manufacturing processes, not only for metal parts, but also for specially designed hybrid parts for more demanding new applications. A wide range of valuable research has been done on the machining of conventional engineering materials. However, when dealing with light alloys and hybrid materials containing them, they need to face new challenges. Particularly, it is important to analyse the suitability of the machining of these alloys in the current context of Industry 4.0, focusing on the development of cost-effective and sustainable processes. This book is a comprehensive source on the machining of light alloys, presenting a collection of both experimental and review studies. The work is arranged in eight chapters, presented by a group of international scholars, which analyse the main problems related to the machining of these alloys from different perspectives. Key Features A comprehensive state-of-the-art reference source on machining of light alloys Provides research on conventional and non-conventional machining process Offers current research topics on sustainable machining Presents research on the machining of hybrid materials using light alloys Includes applications for Industry 4.0 environments Machining of Light Alloys: Aluminum, Titanium, and Magnesium The aim of the book is to serve as a tool for helping researchers and practitioners to face machining challenges and facilitating the development of new industrial applications for light alloys.
Book Synopsis Defence Inflation by : Keith Hartley
Download or read book Defence Inflation written by Keith Hartley and published by Routledge. This book was released on 2018-10-18 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Defence inflation is a recurring factor in determining defence spending. It is widely reported in official government publications and in the trade press, but remains relatively neglected by defence and peace economists. In this book, international contributors from Finland, Norway, Sweden, the UK and the USA distinguish between defence inflation and cost escalation, and identify the causes of both. They use specific case studies to address a wide variety of theoretical and empirical issues and key questions, including the following: Does defence inflation affect all countries? What are its effects? Why does it occur? How (if at all) can defence inflation be controlled? While most industry and trade press devote considerable ink and space to the discussion of defence inflation, cost escalation, and their consequential impact on the purchasing dollars of the armed forces, economists have been relatively silent. This book aims to rectify this oversight through a multinational survey and analysis of the topic, while also identifying the opportunities for further theoretical and empirical research in the field. This book was originally published as a special issue of the journal Defence and Peace Economics.
