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.

Available in PDF, EPUB and Kindle. Book excerpt: A briefing discussing the application of life cycle analysis to the evaluation of proposed investments of R & D and procurement funds. The primary focus of this study has been on aircraft systems and on decisions involving program changes and modifications to systems already in acquisition. In summary, it was observed that present procedures and techniques for making life cycle cost estimates can lead to decisions that have effects opposite to what the decisionmaker is seeking. Opportunities to reduce overall costs may be missed. R & D funds may be invested without achieving an expected O & S cost reduction, thereby increasing life cycle cost. The establishment of a uniform set of procedures for conducting and presenting the results of life cycle analyses should help in two ways. It would compensate for some of the shortcomings of current models and data, and it would provide a useful basis for the development of improved estimating techniques in the future.

This book was released on 1978 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper documents a Texas Instruments 'TI Programmable 59' calculator program that uses the U.S. Air Force Cost Analysis Cost Estimating (CACE) model described in Air Force Regulation 173-10, Volume I, USAF Cost and Planning Factors, dated 6 February 1975. The CACE model was designed with a 'building block' approach to estimate annual operating costs of aircraft weapon systems. The model is useful to Air Force organizations, other Government agencies, and government contractors for cost analysis, life cycle cost exercises, or studies concerned with cost effectiveness comparisons between weapon systems. The program described in this paper provides the user with a means of using the CACE model with a hand-held programmable calculator, eliminating lengthy manual computation or the necessity of using a computer. With its calculator connected to the Texas Instruments 'PC-100A Print Cradle, ' the program allows the user to select among several cost factor input methods, estimate output formats, and summarization options.

Available in PDF, EPUB and Kindle. Book excerpt: On June 15, 2011, the Air Force Space Command established a new vision, mission, and set of goals to ensure continued U.S. dominance in space and cyberspace mission areas. Subsequently, and in coordination with the Air Force Research Laboratory, the Space and Missile Systems Center, and the 14th and 24th Air Forces, the Air Force Space Command identified four long-term science and technology (S&T) challenges critical to meeting these goals. One of these challenges is to provide full-spectrum launch capability at dramatically lower cost, and a reusable booster system (RBS) has been proposed as an approach to meet this challenge. The Air Force Space Command asked the Aeronautics and Space Engineering Board of the National Research Council to conduct an independent review and assessment of the RBS concept prior to considering a continuation of RBS-related activities within the Air Force Research Laboratory portfolio and before initiating a more extensive RBS development program. The committee for the Reusable Booster System: Review and Assessment was formed in response to that request and charged with reviewing and assessing the criteria and assumptions used in the current RBS plans, the cost model methodologies used to fame [frame?] the RBS business case, and the technical maturity and development plans of key elements critical to RBS implementation. The committee consisted of experts not connected with current RBS activities who have significant expertise in launch vehicle design and operation, research and technology development and implementation, space system operations, and cost analysis. The committee solicited and received input on the Air Force launch requirements, the baseline RBS concept, cost models and assessment, and technology readiness. The committee also received input from industry associated with RBS concept, industry independent of the RBS concept, and propulsion system providers which is summarized in Reusable Booster System: Review and Assessment.

Download or read book A New Approach to Modeling the Cost of Ownership for Aircraft Systems written by Kenneth E. Marks and published by . This book was released on 1981-01-01 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Illustrates estimation of support investment costs and recurring operations and support costs through a Model for estimating Aircraft Cost of Ownership (MACO), which also provides a framework for future research. MACO is an outgrowth of an earlier evaluation of the strengths and weaknesses of the most widely used aircraft life cycle cost models. It combines new algorithms for major, maintenance-related costs with formulas drawn from existing models for other cost elements. MACO relates a full set of ownership cost elements to component level reliability and maintainability characteristics and to aircraft design, operations, logistics, and deployment parameters, although the MACO equations would have to be reorganized before they could be used to estimate costs according to the cost structure of the latest Cost Analysis Improvement Group guide. MACO computes resource quantities in units that can be related directly to Air Force programming categories, including base maintenance manning (by work center), depot manning, and recoverable spares inventory levels. Output and input parameters accommodate annual changes in system parameters and operating conditions such as component reliability and aircraft inventory size and activity rates.

Download or read book Translation of the LCC 2 Life Cycle Cost Model to Comply with the CAIG Approved Cost Element Structure written by James E. Botkin and published by . This book was released on 1986 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: This modification of the LCC-2 life cycle cost model cost element structure has separated acquisition costs from O & S costs, and by then adding missing ownership cost elements, has transformed the model into compliance with the Secretary of Defense Cost Analysis Improvement Group's (OSD/CAIG) standard cost element structure for aircraft systems. The modification of the software code to implement the modified cost element structure will once again allow the extensive use of the model for life cycle cost analysis. The modification was accomplished through a comparison of the LCC-2 cost elements with the CAIG approved cost elements and modifying the LCC-2 cost estimating relationships, which produce the cost elements, so as to generate the approved cost elements. Additionally, new cost estimating relationships were devised to supply output for cost elements not previously addressed by the LCC-2 model. Although the model was originally developed for use in the life cycle of avionics systems, the model should be applicable to other aircraft subsystems as well.

This book was released on 1991 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis examines the cost-effectiveness models used by the Air Force and Navy to assist with the decision-making process of their Component Improvement Programs (CIP). The focus on the elements of the two models and the reasonableness of each model's results. A sensitivity analysis was performed on significant input parameters to determine what effect errors in these parameters would have on the predicted return-on-investment (ROI) results. The author concluded that, although the models provide insight into life cycle costs (LCC) of aircraft engines, they are extremely sensitive to errors in certain input variables and should not be relied upon for CIP budget justification.

This book was released on 1978 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first USAF major system acquisition program in which there was explicit consideration given to LCC was the A-X/A-10 Close Air Support Aircraft competition. LCC considerations were quantified using an operating and support (O and S) cost model developed under Project ABLE (Acquisition Based upon consideration of Logistics Effects). Air Force objectives in applying the O and S cost model were: (1) to encourage contractor consideration of operating and support costs in system design, (2) to aid in source selection, (3) to aid in evaluation of engineering change proposals, and (4) to aid in determining the magnitude of award fee (if any) to be granted the contractor. This research has focused on the degree to which these objectives were actually met, problems encountered in meeting them, and suggestions for improving future applications of O and S cost models in LCC programs. Several major deficiencies were discovered in data use and model application that cast serious doubt on the efficacy of this first O and S cost model application and require amelioration to avoid repetition of problems in future acquisition programs.
