【摘要】：进入21世纪以来我国的资源和环境面临更加严峻的挑战,一方面,随着经济的高速发展,石油、天然气以及煤炭等资源的消耗日益加剧,在2014年我国进口原油更是达到创纪录的3.1亿吨,石油的对外依存度更是上升到了59.6%,超过50%这一国际公认警戒线;另一方面,由于粗放型经济增长方式导致的资源浪费以及环境法规的缺失和监管不到位导致我国的环境污染问题愈加严重,从2014年我国中东部各大城市的雾霾天数就可推知我国的环境问题已到了刻不容缓的阶段。本文以此为选题背景,将再制造作为研究主题,再制造以其节约资源能源的特性必将受到人们越来越多的重视,是我国发展循环经济和可持续发展的重要一环,同时也是我国经济发展方式从粗放型增长转变为集约型增长的关键。本文以回收产品的再制造过程为研究主题,通过整理国内外学者关于再制造的相关文献,根据闭环供应链理论、再制造理论以及系统动力学理论等研究成果建立了关于再制造企业再制造过程的系统动力学模型。主要研究了再制造企业的生产和再制造过程,分析了生产率、成品库存和累积订单这三个系统变量在不同需求条件下的行为变化,并对在不同需求条件和不同再制造能力比例下的企业绩效水平进行了评价。本文通过构建回收再制造企业再制造过程的系统动力学模型,提出了再制造企业的再制造能力比例和需求之间的作用关系与作用路径,经过仿真分析主要得到如下结论:1.再制造企业的新产品生产能力对市场需求的反应比回收产品的再制造能力敏捷;2.再制造企业应提高新产品的生产能力以满足较高的市场需求;3.再制造企业应提高回收产品再制造能力以应对较低的市场需求。本文的研究结论可为回收再制造企业的生产和再制造过程提供理论指导。
[Abstract]:Since the beginning of the 21st century, China's resources and environment are facing more severe challenges. On the one hand, with the rapid development of the economy, the consumption of oil, natural gas and coal resources is increasing day by day. In 2014, China imported a record 310 million tons of crude oil, the external dependence of oil rose to 59.6%, more than 50% of the internationally recognized warning line; On the other hand, the problem of environmental pollution in China is becoming more and more serious due to the waste of resources caused by extensive economic growth, the lack of environmental laws and regulations and the lack of supervision. From the haze days of the major cities in central and eastern China in 2014, it is inferred that the environmental problems in China have reached an urgent stage. Based on this background, this paper takes re-manufacturing as the research theme, and the re-manufacture will be paid more and more attention by people with its characteristics of saving resources and energy, and it is an important link in the development of circular economy and sustainable development in our country. At the same time, it is also the key to the transformation of China's economic development from extensive growth to intensive growth. According to the theory of closed-loop supply chain, this paper focuses on the remanufacturing process of recycled products, through sorting out the relevant literatures of domestic and foreign scholars on remanufacturing. The remanufacturing theory and the system dynamics theory have established the system dynamics model about the remanufacturing process of the remanufacturing enterprise. This paper mainly studies the manufacturing and remanufacturing processes of remanufacturing enterprises, and analyzes the behavior changes of the three system variables: productivity, inventory of finished products and cumulative orders under different demand conditions. At the same time, the performance level of enterprises under different demand conditions and different remanufacturing capacity ratios is evaluated. By constructing the system dynamics model of the remanufacturing process of recycling and remanufacturing enterprises, this paper puts forward the relationship and path between the remanufacturing capacity ratio and the demand of the remanufacturing enterprises. Through the simulation analysis, the main conclusions are as follows: 1. The new product production capacity of the remanufacturing enterprise is more responsive to the market demand than the remanufacturing capability of the recycled product; 2. Remanufacturing enterprises should increase the production capacity of new products to meet higher market demand; 3. Remanufacturing enterprises should improve the remanufacturing capacity of recycled products to meet the lower market demand. The conclusion of this paper can provide theoretical guidance for the production and remanufacturing process of recycling and remanufacturing enterprises.
