Abstract

This paper outlines a systematic guideline for remanufacturing process using the Failure Mode and Effect Analysis (FMEA) method in order to estimate the reliability and quality of the remanufactured alternator. The method is just a tool to help, but the remanufacturer must determine the optimal remanufacturing process and specific inspection and production that will turn the alternator as-good-as new and place the product into the market with reliability and quality equal to a new product. FMEA is a method that is widely used in industry and has shown its value and effectiveness in the above remanufacturing case study. Actions taken often result in a lower severity, occurrence or detection rating. Redesign may result in lower severity and occurrence ratings while inserting validation controls and maintenance can reduce the detection rating. The revised ratings are recorded with the originals on the FMEA template form. After these corrective actions and revisions have been established, evaluation of the ranks can be repeated, until the redesign and control parameters comply with safety standards.

재제조는 사용 후 제품을 체계적으로 회수하여 분해, 세척, 검사, 보수조정, 재조립 등의 공정을 거쳐 원래의 성능을 유지할 수 있도록 만드는 과정이다. 자동차 교류발전기를 재제조하기 위해서는 재제조품에 요구되는 품질 및 신뢰성을 확실히 달성하기 위하여 공정 별 복잡한 작업들에 대하여 세부적인 사항들을 결정하고 이를 설계하는 일이 중요하다. 본 연구의 목적은 재제조를 위한 최적의 공정설계를 위해 FMEA를 활용한 체계적인 가이드라인을 제시하여 재제조품의 품질 및 신뢰성을 확보하는데 있다. 코어 부품의 상태 수준에 따른 작업과정과 재정비여부를 결정하기 위해 위험성 지표에 의한 방법도 연구되었다. 특히, 재제조기업의 사례연구를 통하여 FMEA의 유용성과 가이드라인의 적절성을 보여준다.
