生命周期成本 - 技术和应用

This SAE Aerospace Recommended Practice (ARP) describes the concept of life cycle costing with emphasis on LCC techniques and applications as applied to the phases of the program cycle. These phases are:aConceptual studies, research, development, test, and evaluation (RDT&E)bInvestment, or procurementcOperating and support (O&S) or in-servicedDisposal of systems, equipment, and servicesCost elements, estimating techniques and other factors which have a bearing on LCCs are described; including use of cost estimating relationships (CER), simulation techniques, and "top-down"/"bottom-up" approaches. Consideration is also given to:aRisk and uncertainty assessmentsbImpact of economic variations including inflation, interest rates, and exchange rate variationcAdoption of discounting techniques when undertaking investment appraisalsThe use of tailored LCC models is preferred since there is an advantage in adopting a range of approaches particularly for the prediction of the costs of future technology and estimates of uncertainty which are specific to the aerospace industry.Cross Reference: ARP4294
