These cost elements and cost factors form the input and output structure of the Life Cycle Cost Model for Defense Materiel Systems. T

9、e Materiel Systems is the fifth in a series of engineering cost models developed in response to a Marine Corps requirement for a life cycle cost model which can be used in joint Service acquisition programs to insure that each Services life cycle costs be considered. The current model described by t
10、his handbook reflects continuing participation by analysts from all Services and industry to develop a model which is equally appropriate and convenient for all analysts and decision makers who must prepare or use life cycle cost estimates. 2, The Models basic cost element structure is derived from
11、MIL-STD-881, CXCD Cost Analysis Improvement Group (CAG) Osts Cost Development Guides, the Army 11 series pamphlets on life cycle cost, and the Tri-Tac Cost Effectiveness Program Plan. The model addresses all seven major types of Defense materiel systems: surface vehicle, electronic, aircraft, ship,
12、missile, ordnance and space. 3. The report structuresatisfie sthe requirementcofDDI5000.2, Major Systems Acquisitions Procedures, the DD CAIG, Department of the Army 11 series Pamphlets and the Fiscal Director of the Marine Corps. The cost reports, with supporting documentation, are appropriate for
13、presentation to all Services system acquisition review councils and the Defense System Acquisition Review Council (DSARC). 4. The model and this handbook are specifically designed to let the cost analysis community concentrate on the problem of developing cost estimates and determining the economic
14、impact of the many engineering and management decisions which must be made during system acquisition by freeing them from the problem of developing new cost element structures and models for each program. 5. The Model is available to all users through a commercial time sharing arrangement to elimina
15、te conversion problems, minimize software maintenance costs, maintain configuration control of the Model and its Government cost factors and to facilitate the sharing of data between Government and industry by electronic transfer of data bases between users. iii Provided by IHSNot for ResaleNo repro

20、o select those costs which should be developed in any given estimate. The Model allows the analyst the same freedom to select any mixture of cost estimating methodologies appropriate to the analysis, schedule and available data: parametric, analogy, engineering, expert opinion or market price. There
21、 are several major advantages to this approach: a. Independent estimates can be made using the same set of assumptions, thus allowing analysts to focus on estimating methods rather than on structure. b. The analyst is not forced to use dated or inappropriate parametric cost estimating relationships
22、CERS) or procedures. C. Data entry is simplified since only data needed for the analysis is required, Dummy data to make inappropriate CERS work is never required. d. Competitive sensitive methodologies (Government or industry) are protected e. The most relevant cost estimating methodology, at the
23、time of the estimate, can be selected for various parts of the many estimates made during the various phases of the acquisition cycle, allowing the analyst to use a mixture of high and low resolution estimating procedures. f. Model maintenance costs are minimized. g. The Model can be used for any ty
24、pe of system during all phases of development, including product improvement programs. h. The Model is easy to use since the cost estimating methodology is selected by the analyst, not the Model. i. The Model does not require revalidation before each new application since parametrics, if used, are s
25、elected and validated by the analyst and not within the context of the Model. . The decisions 1.4.3. Pite level of detail to which use life cycle cost estimates are as disparate as they are complex. For example, engineering trades generally require a focused level of detail which is sensitive to the
