Available in PDF, EPUB and Kindle. Book excerpt: To understand the availability of data to identify operating and support (O & S) costs, this Note develops aggregative cost estimating relationships to explain O & S costs. A database called VAMOSC is used in conjunction with other information on aircraft characteristics to relate O & S costs per aircraft to flying hours per aircraft, flyaway cost, number of aircraft, and design age. At the total O & S cost level, flyaway cost is an acceptable proxy for aircraft type and the mission design series year of initial operational capability. These cost estimating relationships give impressive explanatory results; whether they have equal predictive power remains to be seen. They may be helpful for assessing Air Force trade-offs between modernization and operating tempo and eventually for understanding the cost of achieving alternative readiness levels.

This book was released on 2009 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Systematically examining the empirical relationship between multiple U.S. Air Force systems' expenditures, flying hours, and fleet sizes, this research suggests a more sophisticated way to think about Air Force costs than is currently used. The report discusses prior research on cost-per-flying-hour calculations--i.e., the practice of multiplying projected flying hours by a cost-per-hour factor in certain segments of the budgetary process. This report looks across Air Force mission designs (systems) and estimates general, historical relationships between expenditure levels and flying hours. A fixed-plus-variable cost structure is estimated with expenditures neither increasing nor decreasing in proportion to flying hours. The author concludes with the policy implications of his findings, noting that current Air Force budgeting approaches likely overestimate funding needs when flying hours are increasing and underestimate needs when flying hours are decreasing.
Download or read book An Appraisal of Models Used in Life Cycle Cost Estimation for USAF Aircraft Systems written by Kenneth E. Marks and published by . This book was released on 1978 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although life cycle analysis is widely used as a management tool, considerable uncertainty still exists about its effectiveness with respect to economic tradeoffs, funding decisions, and resource allocations. This report evaluates some of the most widely used life cycle cost models: AFR l73-10 models (BACE and CACE); the Logistics Support Cost model; the Logistics Composite model; the MOD-METRIC model; AFM 26-3 Manpower Standards; Air Force Logistics Command Depot Maintenance Cost Equations; the DAPCA model; and the PRICE model. The models are rated within a framework incorporating a set of cycle cost elements and a set of cost driving factors. Color-coded illustrations summarize the results. The models are shown to have many shortcomings that limit their usefulness for life cycle analyses in which estimates of absolute, incremental cost are required. Specific areas are identified where driving factor/cost element combinations are not adequately addressed.

Download or read book Estimating Operating and Support Models for U S Air Force Aircraft written by Ming-Cheng Wu and published by . This book was released on 2000-03-01 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The USAF Visibility and Management of Operating and Support Cost (VAMOSC) system is an information system which reports historical O&S costs of Air Force weapon systems. Source data for VAMOSC comes from a number of USAF financial, logistics, inventory, and operating systems. This centralization and consolidation of O&S cost data provides information that helps weapon system managers and planners make better decisions for DoD and USAF in the operation, maintenance, and management of weapon systems. In earlier analysis, flyaway costs, flying hours, number of aircraft and aircraft fleet age were identified as important variables for explaining and predicting O&S Costs. The earlier models need to be re-estimated to determine whether aircraft types and operation mission types are applicable and how they have separate effects on O&S costs. This thesis shows that the structure of the earlier models continues to be applicable. The models, therefore, are a useful tool for understanding the determinants of O&S cost.
Download or read book Budget Estimating Relationships for Depot level Reparables in the Air Force Flying Hour Program written by Gregory G. Hildebrandt and published by Rand Corporation. This book was released on 2007 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Budget estimating relationships (BERs) for flying depot-level reparables (DLRs) explain the direct effect of specified variables on obligated funds associated with spare parts that directly support the U.S. Air Force (USAF) Flying Hour Program. In FY02, net sales of DLRs to Air Force commands hit historic highs. To provide the Air Force Cost Analysis Improvement Group with a tool to better understand the commands-- budgetary submissions, we develop several explanatory BERs to understand why flying DLRs are at their particular levels. Using longitudinal regression statistical methods, we explain the historical net sales of flying DLRs using estimating models that relate net sales to the contemporaneous values of aircraft characteristics, operational tempo, and time-related variables. This is but one part of a larger project to develop better estimating methods for use by the acquisition community and to examine the impact of Air Force and DoD policies on weapon system costs. The findings will also be of interest to those in the national security community who are involved in analyzing alternative military postures, and to members of the aircraft industry's analytical community.
Download or read book Operating and Support Cost Estimating Guide Sample Analysis Air Force Aircraft at DSARC III written by COST ANALYSIS IMPROVEMENT GROUP WASHINGTON D C. and published by . This book was released on 1980 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: The following sample of a CAIG(Cost Analysis Improvement Group) Operating and Support Cost Estimate Report covering a hypothetical case has been developed to further assist the cost analyst in the preparation of cost estimating reports submitted to the DSARC and CAIG during the acquisition process of a new weapon system. The sample is intended to show an example of how Operating and Support Costs can be developed for CAIG review with available data bases and one example of an appropriate format for presentation of cost estimates. The existing A-7E data base was used only to illustrate the need to relate an estimate to an existing similar system and to ensure a constant relationship between values and the Cost Element Structure. Each case should address that data which is the most complete and accurate for its purposes. The level of detail depicted in this example may be greater than that which is available or appropriate to a specific case.
Download or read book A Parametric Cost Model for Estimating Operating and Support Costs of U S Navy Aircraft written by Mustafa Donmez and published by . This book was released on 2000-12-01 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study provides parametric O&S cost models for future US Navy aircraft acquisition programs based on physical and performance parameters. The proposed parametric cost models provide decision makers with a tool for developing rough-order-of-magnitude annual O&S cost estimates for future US Navy aircraft acquisition programs. The historic aircraft cost data was provided by the Naval Center for Cost Analysis (NCCA) in a spreadsheet format and the data were extracted from the Navy Visibility and Maintenance of Operating and Support Cost (VAMOSC) data warehouse. After validating the assumption that the average annual O&S cost for any aircraft type/model/series is constant from year to year, cost estimating relationships are developed. The first model developed is based on multivariate regression. In this case, forward stepwise regression was used to find the model with the best fit. Since the multivariate regression model turns out to be impractical, having more than 30 variables in the equation, a tree-based model is presented as an alternative. Additionally, single variable cost estimating relationships are formulated based on the physical and performance parameters length, weight, and thrust.
Download or read book An Overview of Acquisition Reform Cost Savings Estimates written by and published by . This book was released on 2001 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: In support of the project "The Cost of Future Military Aircraft: Historical Cost Estimating Relationships and Cost Reduction Initiatives," this study gives an overview of a wide range of published estimates and projections of potential cost savings that are attributed to a variety of weapon system acquisition reform (AR) measures. These estimates are compared in accordance with a taxonomy developed by the authors. Although the origins and quality of the estimates are discussed, no independent estimates have been generated, nor are the existing published estimates analyzed in depth. Rather, the authors present a taxonomy of current AR initiatives; review published estimates of the cost savings attributed to these initiatives; report the views of industry and government officials on the potential cost savings from AR; and discuss the structuring and implementation of programmatic AR measures based on lessons learned from existing AR pilot programs. The project is in the RAND Project AIR FORCE Resource Management Program. The research is sponsored by the Principal Deputy, Office of the Assistant Secretary of the Air Force (Acquisition), and by the Office of the Technical Director, Air Force Cost Analysis Agency. This study should be of interest to government and industry officials concerned with assessing the potential cost savings that current AR measures may generate when applied to major weapon system R & D and procurement programs. The information collection cutoff date was December 1999.

Download or read book Aircraft Airframe Cost Estimating Relationships written by Ronald Wayne Hess and published by . This book was released on 1987 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents generalized equations for estimating the development and production costs of aircraft airframes. It provides separate cost estimating relationships (CERs) for engineering, tooling, manufacturing labor, and quality-control hours; manufacturing material, development support, and flight-test cost; and total program cost. The CERs, expressed in the form of exponential equations, were derived from a database consisting of 34 military aircraft with first flight dates ranging from 1948 to 1978. In addition to the basic objective of developing an updated set of airframe CERs, the study also examined three specific possibilities for improving CER accuracy: (1) stratifying the full estimating sample into subsamples representing major differences in aircraft type; (2) incorporating variables describing program structure and airframe construction characteristics; and (3) for the fighter aircraft only, incorporating an objective technology index into the equations.
Download or read book Unit Cost Analysis written by John Frederic Schank and published by RAND Corporation. This book was released on 1986 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents a consistent and complete methodology for comparing annual operating and support costs of active and reserve units within and across all components of the force. Existing service models and data were modified or manipulated to create active and reserve annual cost models and cost factors. The report describes the general approach and uses service-specific case studies to demonstrate methods and cost factor derivations. Case studies include: Air Force F-4D and C-130E squadrons; Army mechanized infantry, tank, field artillery, and combat engineering battalions; and Navy F-4S squadrons and FF1052 frigates. Results, given in FY 1983 dollars, show wide variances in annual active and reserve unit costs across units and services, emphasizing the need for a case-by-case approach to unit costing. Technical appendixes present the detailed descriptions of cost factor derivations and data sources. A companion document, R-3210/1-RA, provides a summary of this report in executive briefing format.

This book was released on 1997-06-01 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research addresses the estimation of operation and support (O&S) costs of the Brazilian Air Force KC-137 aircraft. BAF lacks an established set of procedures for computing ownership costs of such aircraft, which prejudices the elaboration of cost-benefit analysis and allocation of budget resources. The purpose of the study is to develop an O&S cost breakdown structure and a set of cost estimating equations that will be used to estimate the ownership costs of the KC-137 aircraft during their expected service life.

Available in PDF, EPUB and Kindle. Book excerpt: Designed to produce time-phased total manpower and dollar requirements estimates for 15-year projections of alternative future USAF forces and support structures, the USAF Total Force Cost Model--sometimes referred to as the FORCE model--is currently operating on computers in the Air Staff Cost and Economic Analysis Division, Directorate of Management Analysis, Comptroller of the Air Force. This report presents an overview of the model, including its basic purposes and its relationship to the planning and programming process. Some examples and suggested applications are presented. Only the general features of the model and the methodology it employs are discussed. The FORCE model has potential for application in analysis of future forces for research and development planning; studies of alternative weapon systems for mission-oriented subsets of the force; and analysis of alternative future basing plans, training structure, or other support issues.
