Elevator manufacturers are responsible for securing the safety and maintaining the performance, cleanliness and cosmetic appearance of the elevators which they have sold. The purpose of this paper is to develop the cost-optimized after-service strategy for an elevator part. First, in order to find the optimum maintenance method, the replacement probability and the inspection probability of the part are derived theoretically under each of the three maintenance methods; Time Based Maintenance(TBM), Condition Based Maintenance(CBM), and Breakdown Maintenance(BM). Then, the approach to determine the cost-optimized maintenance is presented and the relationship between the failure characteristic of the part and the cost-optimized maintehance is discussed. The result of using the proposed approach is compared with the one obtained by Online Quality Engineering (Taguchi Methods). Finally, from numerical experiments, it is shown that this approach can provide a more cost-effective and better maintenance method than the one given by Online Quality Engineering.
