An Analysis And Assessment Of Automotive Parts' Remanufacturing Based On Automotive Remanufacturing Engineering

When we entered the 21st century, as the development of science and technology, mankind have created a lot of material wealth, but at the same time, we also have consumed natural resources and polluted the ecological environment we live. According to the statics, 70% of our pollutants are from manufacturing industry, which we should put forward higher requirement in circular economy of manufacturing and green manufacturing sector. And further the manufacturing process is not only a waste of our limited material resources, but also a waste of our energy. Re-manufacturing, as a engineering technology which meet the strategy of sustainable development and suit to the recycling economy and green manufacturing phase come.Re-manufacturing is a technology that can repair a product with being re-manufacturing back to a new one which keep its functionality, durability and also other indicators, at least, at the same level of the original product. This paper has a research on the origin of re-manufacturing and its current development at home and abroad, put forward evaluation index of being re-manufacturing with which consistent, and further establish evaluation system of automotive parts'being re-manufacturing, also make a analysis related to some typical automotive parts'being re-manufacturing.At the beginning, it has an elaboration of the re-manufacturing concept, and make a distinction between re-manufacturing and repairing. It also analyze the present situation of this industry and put forward the necessity of developing re-manufacturing industry.Further, it analyzes the status of automotive re-manufacturing industry and some related key processes, put forwards the past method about automotive parts'being re-manufacturing. And then, it presents a new assessment method of automotive parts' being re-manufacturing based on fuzzy multi-attribute decision and establishes an evaluation model.It specifically has a related assessment of automotive important wear parts' re-manufacturing (such as automotive steering and the piston of automotive engine). Finally, having an analysis and summary to the auto parts which have assessed is necessary. After that, it is crucial to give some follow-up guidance.
