寿命周期费用(LCC)方法提出和应用已20余年。1971年美国国防部发布的《寿命周期费用评价采购指南》(LCC—1)等文件,是在国防采办中正式应用LCC的开始。在整个70年代,美国国防部和各军兵种陆续发布了一批指令、指示、规则、指南和手册,使有关规定和方法更加具体化。这一时期所发表的文献从LCC方法的各方面进行较深入的研究,包括费用的分解、估算、建模、校核以及分析和评价,表明LCC的研究和应用在逐步深入。80年代正式发布的指令性文件逐渐减少,说明LCC方法和有关规定已经逐步完善,应用更加广泛。
The life cycle cost (LCC) method has been proposed and applied for more than 20 years. In 1971, the United States Department of Defense released the “Guide to the Life Cycle Cost Evaluation Procurement Guide” (LCC-1) and other documents, which formally used LCC in defense procurement. Throughout the 1970s, the U.S. Department of Defense and various military units successively issued a number of directives, instructions, rules, guidelines, and manuals to make the relevant regulations and methods more specific. The documents published during this period have conducted in-depth research on various aspects of the LCC method, including cost decomposition, estimation, modeling, verification, and analysis and evaluation, indicating that the research and application of LCC is gradually deepening. The directive documents officially released in the 1980s gradually decreased, indicating that the LCC method and related regulations have been gradually improved and applied more widely.
