摘要

由於退化性產品在保固期內進行保養維護工作時，經常受限於各種資源限制而無法按預定計畫實施，本研究將針對這種情況探討主動維護保證策略。首先建構資源限制下產品之主動維護保證成本模式，接著分析不同狀況下最佳策略的結構及性質，並藉由這些性質提供有效的演算法尋求包括最佳保養程度、保養次數、及保養時機等決策變數的最佳主動維護保證策略，使得總期望保證成本最低。最後針對具有韋伯壽命分配的產品推導最佳策略，並且進一步獲得最佳策略之解析解。

This study investigates preventive-maintenance warranty policies for repairable product sunder resource constraints. To reduce product failures, preventive maintenance is widely adopted in practice, especially when the product is complex and/or expensive. However, in practice, there usually exist some resource constraints in performing a preventive maintenance action for deteriorating products. Therefore, products cannot be maintained back to a predetermined condition. In this study, a general warranty cost model for repairable products under resource constraints is established. Based on the model, the properties of optimal preventive-maintenance warranty policies are investigated. Using these properties, algorithms are provided to derive the optimal policies such that the expected total warranty cost is minimized. Finally, when the lifetime distribution of a product is Weibull, a closed-form solution of the optimal policy is obtained.
