Determination of Failure Cause in Remanufacturing

Remanufacturing is a series of processes which makes the old product functionally equivalent and visually indistinguishable from a new product. In this research, we analyzed characteristics of target product (power steering oil pump of vehicle) and designed a new algorithm which let us know the cause process of possible failures that can be occurred after remanufacturing. Problems of remanufacturing process were identified by comparing and evaluating the most serious causes deduced by the algorithm which were applied to each failure type.
