- Abstract
- Purpose: This study proposes the optimal PM (preventive maintenance) policy of leased equipment for lessee’s decision-making using two types of reliability condition.
Methods: We consider reliability threshold based PM model. Equipment reliability is estimated and used as condition variable. The effect of repair for maintenance is imperfect and represented by age reduction factor.
Results: We provide two PM policies. Policy 1 is focused on minimized total cost. This policy guarantees reliability threshold until last maintenance action. Policy 2 focus on maintaining reliability threshold during leased period. The proposed approach provides optimal reliability threshold under number of PM. Through result, we finally construct decision-making process for lessee using reliability threshold and end of reliability.
Conclusion: This study provides two PM policy for lessee’s decision-making. Through numerical example, we get a result of optimal reliability threshold, number of PM, optimum alternative under lessee’s reliability condition.
