碩士 === 國立臺灣科技大學 === 工業管理系 === 102 === Compare with most studies dividing the reliability issues into design or evaluate a system’s life cycle by a required reliability level to determine an optimal maintenance strategy for keeping a given operating performance, there are seldom studies concentrates on an optimal mid-life reliability improvement strategy to minimize a system’s life cycle cost. This study constructs a simple linear regression model to predict the investment for reliability improvement and use a customer-based life cycle cost model from UNIFE to determine an optimal total life cycle cost, using the hypothesis of the lowest life cycle cost is the optimal solution. Also, applying the model to industrial pumps as case to prove that through reliability improvement, pumps’s expected maintenance cost will decent and so the total life cycle cost.
