Flexible Restoration for Remanufacture of Rolling Stock Components

日益严格的环境法规，如WEEE和报废车辆指令(EoL)要求废物的再利用。再制造通过将EoL产品恢复到工作状态而不是仅将它们减少到其原材料价值来增加废流的价值，保留了用于制造新产品的80%以上的材料和能量[珀尔，2010]，因此被认为是循环经济的重要元素。修复是再制造的一项关键操作，将有缺陷的部件恢复到使用寿命，可能占到总再制造成本的50%。目前，修复仍是临时的。这项可行性研究侧重于因退回缺陷产品质量不同而导致的一次性生产，旨在评估和验证机车车辆部件再制造的新的灵活修复。这将解决阻碍采用再制造的主要障碍之一，即无法以与大规模生产类似的成本进行再制造。这项研究的结果可能导致效率的显著提高，从而促进再制造业的扩张。

Increasingly stringent environmental regulations such as WEEE and End-of-Life (EoL) Vehicle Directive require the reuse of waste. Remanufacturing adds value to waste streams by returning EoL items to working order rather than reducing them to their raw material value only, preserves more than 80% of the material and energy used to manufacture a new product [PEARL, 2010], thus is considered as an important element of the circular economy. Restoration, which returns defective parts back to service life is a critical operation of remanufacturing and could account for up to 50% of total remanufacturing cost. Currently restoration is still ad-hoc. Focusing on one-off production resulting from the differential quality of returned defective products, this feasibility study aims to assess and validate a new flexible restoration for the remanufacture of rolling stock components. This would address one of the major barriers hindering the uptake of remanufacturing which is the inability to remanufacture at a cost similar to that of mass production. The results of the study could lead to significant improvement in efficiency, thus promoting the expansion of the remanufacturing industry.
