Book Synopsis Investigating Optimal Replacement of Aging Air Force Systems by : Edward G. Keating
Download or read book Investigating Optimal Replacement of Aging Air Force Systems written by Edward G. Keating and published by . This book was released on 2004 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of a continuing project on aging aircraft and the replacement-or-repair decision, the authors develop a parsimonious model of the decision and apply it to the U.S. Air Force's C-21A transport and KC-135 tanker aircraft. They find that, for the C-21A, it probably would be appropriate to undertake a 20,000 flight hour system and component replacement schedule-prescribed renovation in the 2012 timeframe, but the aircraft should be retired around 2020.

Book Synopsis The Maintenance Costs of Aging Aircraft by : Matthew C. Dixon
Download or read book The Maintenance Costs of Aging Aircraft written by Matthew C. Dixon and published by Rand Corporation. This book was released on 2006 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Air Force is grappling with the challenge of aging fleets and the optimal time to replace them. This monograph examines commercial aviation data to draw inferences about aging aircraft that may be relevant to the Air Force. It focuses on "aging effects"-i.e., how aircraft maintenance costs change as aircraft grow older. Although commercial aircraft clearly differ from military aircraft, the aging-effect estimates might help the Air Force to project changing maintenance costs over time.
Book Synopsis Aging Avionics in Military Aircraft by : National Research Council
Download or read book Aging Avionics in Military Aircraft written by National Research Council and published by National Academies Press. This book was released on 2001-05-07 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extending the life of an airframe has proven challenging and costly. Extending the life of an avionics system, however, is one of the most critical and difficult aspects of extending total aircraft system lifetimes. Critical components go out of production or become obsolete, and many former suppliers of military-grade components have gone out of business. From 1986 to 1996, for example, the percentage of discontinued military/aerospace electronic devices nearly doubledâ€"from 7.5 percent to 13.5 percent. In addition, legacy avionics systems, which were designed to meet requirements of the past, generally lack the full capability to perform new missions, meet new threats, or perform well in the new information-intensive battlefield environments. As the legacy aircraft fleet ages, avionics systems will become more and more difficult to support and maintain. Whereas the military once provided a large and profitable market for the electronics industry, the military electronics market today constitutes less than 1 percent of the commercial market. As a result, the military must increasingly rely on commercial off-the-shelf (COTS) technologies for its avionics hardware and software. Although COTS items are generally less expensive than comparable items designed especially to meet military specifications, the technology-refresh cycle for COTS is typically 18 months or less, which exacerbates the obsolescence problem for aircraft whose lifetimes are measured in decades. The short refresh cycle is driven mostly by the tremendous advances in computer systems, which comprise an increasing percentage of avionics content. In response to a request by the Assistant Secretary of the Air Force for Acquisition, the National Research Council convened the Committee on Aging Avionics in Military Aircraft, under the auspices of the Air Force Science and Technology Board, to conduct this study. This report summarizes the following: Gather information from DoD, other government agencies, and industrial sources on the status of, and issues surrounding, the aging avionics problem. This should include briefings from and discussions with senior industry executives and military acquisition and support personnel. A part of this activity should include a review of Air Force Materiel Command's study on diminishing manufacturing sources to recommend ways to mitigate avionics obsolescence. Provide recommendations for new approaches and innovative techniques to improve management of aging avionics, with the goal of helping the Air Force to enhance supportability and replacement of aging and obsolescing avionics and minimize associated life cycle costs. Comment on the division of technology responsibility between DoD and industry.

Book Synopsis Aging Aircraft Repair-Replacement Decisions With Depot-Level Capacity as a Policy Choice Variable by :
Download or read book Aging Aircraft Repair-Replacement Decisions With Depot-Level Capacity as a Policy Choice Variable written by and published by . This book was released on 2005 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Keating and Dixon (2003), we presented a model for determining when it would be optimal to retire, rather than continue to repair, an aging system. This work extends Keating and Dixon along two dimensions. First, we extend our methodology to examine whether a proposed modification (mod) is worthwhile relative to retiring an aircraft. Second, we develop a new methodology to explore the desirability of additional investment in depot-level capacity.

Download or read book Report on Sustaining Air Force Aging Aircraft Into the 21st Century written by United States. USAF Scientific Advisory Board and published by . This book was released on 2011 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: "As many of its fleets of legacy aircraft types are kept in service well beyond their planned services lives (sometimes in age, sometimes in usage, sometimes both), the United States Air Force (USAF) faces numerous engineering and resource challenges for the continued, cost effective sustainment of those aging systems. This report details the recommendations made by the USAF Scientific Advisory Board's Sustaining Aging Aircraft (SAA) Study to best position the Air Force to meet those challenges. The SAA Study Panel visited a cross section of military and commercial aircraft maintenance organizations to assess sustainment practices and identify technologies that can extend system life and ease maintenance costs. The Study identified specific aircraft systems, in addition to structures and engines, that contribute to safety, availability, and effectiveness for aging aircraft; examined commercial practices in airlines, air freight services, and other industries, and evaluated how they might be applied to meet USAF needs; and identified technology needs and technology approaches that can be applied or developed to extend life or ease maintenance of these aircraft systems, while facilitating future adaptations and performance enhancements of the aircraft."--p. 211.

Book Synopsis A Survey of Aircraft Structural-life Management Programs in the U.S. Navy, the Canadian Forces, and the U.S. Air Force by : Yool Kim
Download or read book A Survey of Aircraft Structural-life Management Programs in the U.S. Navy, the Canadian Forces, and the U.S. Air Force written by Yool Kim and published by Rand Corporation. This book was released on 2006 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: The average age of aircraft in the U.S. Air Force is 22, making aging an increasing concern. The Air Force program responsible for maintaining the structural safety of its aircraft faces challenges, however, such as budgetary pressures, regulations, and communication issues. The authors sought insights on these issues by comparing similar programs in other services. Their observations suggest the value of clear policies, independent assessments, standard metrics, and open and clear communication.
Book Synopsis Programmed Depot Maintenance Capacity Assessment Tool by : Elvira N. Loredo
Download or read book Programmed Depot Maintenance Capacity Assessment Tool written by Elvira N. Loredo and published by Rand Corporation. This book was released on 2007 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph describes a model for evaluating the combined capacity of organic (U.S. Air Force owned and operated) and contractor maintenance assets to meet aircraft programmed depot maintenance (PDM) workloads. The PDM Capacity Assessment Tool (PDMCAT) forecasts the average number of aircraft that will be in PDM status each year over several decades, based on the initial number of aircraft in PDM status, the physical capacity of the facility or facilities (number of docks available for conducting PDM work), the PDM induction policy (the period allowed between the completion of one PDM and the start of the next), and the minimum hands-on flow time (the minimum time it would take a facility to complete a PDM if only one aircraft were in PDM status). While not directly part of the model, the derived induction data can be used to estimate both near- and long-term obligation authority requirements for different induction policies, labor rates, and workload forecasts. To illustrate the model's operations and capabilities, we applied the model to evaluate the U.S. Air Force's current capacity for supporting KC-135 PDM and examined several options for improving both near- and long-term availability. In the process, we discovered that, while future annual fleet costs increase and availability decreases with age and workload, they do so rather less rapidly because the aircraft induction rates (the number of aircraft inducted each year) decrease as the PDM flow time increases. This leads to a less-drastic cost and availability forecast than usual.
Book Synopsis Aging Avionics in Military Aircraft by :
Download or read book Aging Avionics in Military Aircraft written by and published by . This book was released on 2001 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NRC was asked by the Assistant Secretary of the Air Force for Acquisition to examine issues associated with aging avionics in military aircraft. An ad hoc Committee was formed under the Air Force Science and Technology Board and the Commission on Engineering and Technical Systems (now Division on Engineering and Physical Systems) at the National Academy of Sciences in February 2000. The National Academies was tasked to gather all pertinent information, include a review of Diminishing Manufacturing Sources, and provide recommendations on new approaches and innovative techniques to improve management of aging avionics. The overall goal was to help the Air Force to enhance supportability and replacement of aging and obsolescing avionics and minimize associated life cycle costs. Avionics systems, like all computer-based systems, are operating on a life cycle of about two to three years, while the systems within which they are imbedded have life cycles as long as several decades. This report identified management, technical, and business issues and solutions to the problem of aging and obsolescing avionics systems in military aircraft.
Book Synopsis Valuing Programmed Depot Maintenance Speed by : Edward Geoffrey Keating
Download or read book Valuing Programmed Depot Maintenance Speed written by Edward Geoffrey Keating and published by Rand Corporation. This book was released on 2006 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Part of a larger RAND Project Air Force study on capability-based programming, this report introduces a revealed preference methodology to estimate the value to the United States Air Force of expediting F-15 fighter jet programmed depot maintenance (PDM). Such a valuation estimate would be useful in depot-level cost-benefit analysis. The authors rely on the fact that the Air Force has chosen to pay for intermittent PDM on F-15s to assert that F-15s must have enough value after PDM visits to justify PDM costs. Air Force expenditure data suggest that a typical fiscal year 2005 PDM visit cost about $3.2 million. Using the aircraft valuation curves consistent with PDM being worthwhile, the authors find that expediting an F-15's last PDM visit by a month must be worth at least $60,000. However, using a plausible annual aircraft valuation decline rate, they find that expediting an old F-15's last PDM visit by a month would be worth around $75,000, while expediting a new F-15's first PDM visit by a month would be worth more than $180,000. This report also explores various robustness enhancements. Consideration of aging aircraft issues, for instance, tends to increase the estimated value of expedited PDM.
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.
Book Synopsis Military Cost-Benefit Analysis by : Francois Melese
Download or read book Military Cost-Benefit Analysis written by Francois Melese and published by Routledge. This book was released on 2015-03-27 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first comprehensive book on Military Cost-Benefit Analysis and provides novel approaches to structuring cost-benefit and affordability analysis amidst an uncertain defense environment and cloudy fiscal prospects. Lifting the veil on military Cost-Benefit Analysis, this volume offers several new practical tools designed to guide defense investments (and divestments), combined with a selection of real-world applications. The widespread employment of Cost-Benefit Analysis offers a unique opportunity to transform legacy defense forces into efficient, effective, and accountable 21st century organizations. A synthesis of economics, statistics and decision theory, CBA is currently used in a wide range of defense applications in countries around the world: i) to shape national security strategy, ii) to set acquisition policy, and iii) to inform critical investments in people, equipment, infrastructure, services and supplies. As sovereign debt challenges squeeze national budgets, and emerging threats disrupt traditional notions of security, this volume offers valuable tools to navigate the political landscape, meet calls for fiscal accountability, and boost the effectiveness of defense investments to help guarantee future peace and stability. A valuable resource for scholars, practitioners, novices and experts, this book offers a comprehensive overview of Military Cost-Benefit Analysis and will appeal to anyone interested or involved in improving national security, and will also be of general interest to those responsible for major government programs, projects or policies.
