摘要

機器設備的預防保養在高效率的工業系統中已是不可或缺的例行計畫，若設備零件發生故障才進行更換，將使正常運作的系統停頓而造成損失。本研究考量具有壽命分配之機器設備，根據可靠度更新理論，於使用壽命期間採取適當次數的預防保養及維修，建構壽命期間內總期望預防保養及維修與更新成本之模式，其中考量預防保養成本及故障維修與更新成本兩項因素，利用電腦軟體撰寫數值模擬程式進行求解，找尋最佳預防保養週期，以達到總期望預防保養與維修成本最小化之目標。並針對相關參數進行敏感度分析，最後提出九點結論，作為後續研究及實務應用之參考。

Preventive maintenance is an important policy for efficient industrial system. If no preventive maintenance was executed and the equipment is replaced until it breakdown, then the company will bear huge losses. When the lifetime distribution of machinery or equipment was given and based on the stochastic process and renewal theorem, we can construct a mathematical programming model to search for an optimal preventive interval then minimize the total expected cost. The total cost includes preventive cost and maintenance or renewal cost. In this paper, we design a numerical integral program to search for the optimal solution. Furthermore, the sensitivity analysis was taken to realize the influence of variant parameters. Finally, nine conclusions are drawn for future studies and practical applications.
