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: AIR 1939 addresses communication of LCC data between equipment suppliers, aircraft engine producers, aircraft manufacturers, and users, as illustrated in Figure 1. The LCC data categories addressed include: research, development, test and evaluation (RDT&E); acquisition (initial procurement and investment); and operating and support (O&S) costs. While input and output formats are suggested, calculation procedures and cost methodology are specifically excluded since many LCC models preferred by the industry are company sensitive or proprietary (Figure 1). The relationship of LCC input data to program phase is described. Ground rules and assumptions are addressed. A glossary of LCC terms is provided. The LCC impact of propulsion systems on other aircraft systems is considered.This document was specifically developed for military propulsion system cost analysis. However, it is believed that a functional relationship exists between military and commercial Life Cycle Cost analysis and that with some interpretation, sections of AIR 1939 might be applicable to commercial propulsion systems as well.In summary, AIR 1939 provides a basis for LCC calculations, for monitoring of LCC status resulting from trade studies, and for tracking status against LCC goals in a consistent manner, thus permitting quantitative, comparable assessment. AIR 1939 guidelines recommend that a Life Cycle Cost presentation include consideration of overall cost rather than a sub-optimization of just one or a few cost elements. The LCLS committee discussed AIR1939 and has decided that the best course of action is stabilization.

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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: With the increase competition among airlines to capture the customer base, more and more airlines demanding the aerospace industry to produce aircraft with high reliability and low maintenance costs. Similarly, aircraft manufacturers that once had the monopoly in various sectors, that is, small & large jets, propellers, business jet are now facing fierce competition. In response to airline industry, manufacturers are increasingly paying more attention to optimize new and current designs to improve reliability while low operating cost aircraft. This paper covers one of several methodologies available to optimize the design of an aircraft. The Life Cycle Cost (LCC) analysis is a powerful tool that has been used extensively on two new designs at Bombardier Aerospace. Several publications are available in public domain covering theoretical aspects of Engineering Economics, including Life Cycle Cost. The Life Cycle Cost analysis is a systematic approach in applying engineering economics to determine the best solution for a design over the useful life of the aircraft, from an economic standpoint.

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 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report illustrates estimates 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 (CAIG) 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.
