【摘要】：经济社会特别是工业的快速发展,造成了大量工业产品的生产制造和报废处理,一方面既产生了资源浪费和能源短缺问题,另一方面也给生态环境造成了巨大压力。再制造是一种以节约资源能源、保护环境为出发点的循环经济发展模式。近年来,我国再制造产业发展势头迅猛,已经成为世界上重要的再制造中心之一,并且在基础应用研究和技术应用开发等方面也走在了世界前列。但我国目前的再制造产业仍处于发展的初级阶段,关于再制造的相关研究还不够深入,相关理论和方法还不够完善。目前关于发动机再制造清洗的研究多是从技术角度进行的开发和研究。考虑再制造行业的特点及发动机再制造清洗的技术特点,发动机再制造清洗具有独特的清洗目标和要求,发动机再制造清洗不能直接复制其他行业的经验。再制造清洗更决定了再制造产品的质量和成本,并直接关乎再制造的可行性。因此,迫切需要对发动机再制造清洗技术进行成本分析。本文在分析再制造、生命周期、技术经济相关理论和方法的基础上,结合发动机再制造清洗技术和生命周期成本的相关研究,确定了研究问题。以再制造产业为背景,以发动机再制造清洗技术为出发点,采用生命周期成本方法进行分析。首先,结合产品生命周期和技术发展周期理论,对发动机再制造清洗技术的生命周期阶段进行划分。将发动机再制造清洗技术的生命周期成本划分为研发设计阶段、制造加工阶段、使用维护阶段、报废处置阶段成本,以及单独核算的环境成本。其次,根据各阶段所消耗的费用,建立生命周期成本分解结构。并综合利用不同的成本估算方法对各阶段成本进行估算,建立发动机再制造清洗技术的生命周期成本分析的简单模型。之后,以某再制造企业所用的清洗技术为实例,估算了其生命周期成本。另外,对发动机再制造清洗技术的生命周期成本进行了敏感性分析,从定量角度研究了有关因素的变化对目标指标的影响程度。预先选定的敏感性因素为环保政策和技术进步,通过实例的敏感性分析进行验证,表明了环保政策和技术进步的变化对发动机再制造清洗技术的生命周期成本的影响。
[Abstract]:The rapid development of economy and society, especially industry, has caused a large number of industrial products to be produced and disposed of. On the one hand, it has produced the problems of resource waste and energy shortage, on the other hand, it has also caused great pressure to the ecological environment. Remanufacturing is a kind of circular economy development mode, which is based on saving resources and protecting environment. In recent years, China's remanufacturing industry has developed rapidly and has become one of the most important remanufacturing centers in the world, and has also been in the forefront of the world in basic application research and technology application development. However, the current remanufacturing industry in China is still in the primary stage of development, the related research on remanufacturing is not deep enough, and the relevant theories and methods are not perfect enough. At present, the research on engine re-manufacturing cleaning is mostly from the technical point of view of development and research. Considering the characteristics of the remanufacturing industry and the technical characteristics of the engine remanufacturing cleaning, the engine remanufacturing cleaning has unique cleaning objectives and requirements, and the engine remanufacturing cleaning can not directly replicate the experience of other industries. Remanufacturing cleaning determines the quality and cost of remanufactured products and directly relates to the feasibility of remanufacturing. Therefore, there is an urgent need for cost analysis of engine remanufacturing cleaning technology. In this paper, based on the analysis of the theories and methods of remanufacturing, life cycle, technology and economy, combined with the related research of engine remanufacturing cleaning technology and life cycle cost, the research problems are determined. Taking the remanufacturing industry as the background and the engine remanufacturing cleaning technology as the starting point, the life cycle cost method is used to analyze. Firstly, combined with the theory of product life cycle and technology development cycle, the life cycle stage of engine remanufacturing cleaning technology is divided. The life cycle cost of engine remanufacturing cleaning technology is divided into R & D design stage, manufacturing and processing stage, usage and maintenance stage, scrap disposal stage, and environmental cost accounting separately. Secondly, the life cycle cost decomposition structure is established according to the cost consumed by each stage. A simple model of life cycle cost analysis of engine remanufacturing cleaning technology is established by synthetically using different cost estimation methods to estimate the cost of each stage. Then, the life cycle cost of a remanufacturing enterprise is estimated by taking the cleaning technology used in the remanufacturing enterprise as an example. In addition, the life cycle cost of engine remanufacturing cleaning technology is analyzed, and the influence of the factors on the target index is studied from the quantitative point of view. The sensitivity factors selected in advance are environmental protection policy and technological progress. The results of sensitivity analysis show that the change of environmental protection policy and technological progress has influence on the life cycle cost of engine remanufacturing cleaning technology.
