Flexible Restoration for Remanufacture of Rolling Stock Components

越来越严格的环境法规，如WESTERN和报废（EoL）车辆指令，要求对废物进行再利用。再制造通过使EoL物品恢复工作状态而不是仅将其降低到原材料价值来增加废物流的价值，保留了用于制造新产品的80%以上的材料和能源[PEARL，2010]，因此被认为是循环经济的重要元素。修复是将有缺陷的零件恢复到使用寿命，是再制造的关键操作，可能占再制造总成本的50%。目前，修复工作仍处于临时性阶段。该可行性研究的重点是由于退回缺陷产品的质量差异而导致的一次性生产，旨在评估和验证用于机车车辆部件再制造的新的灵活恢复。这将解决阻碍再制造的主要障碍之一，即无法以类似于大规模生产的成本进行再制造。研究结果可能导致效率的显著提高，从而促进再制造产业的扩张。

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.
