摘要

本文為租賃系統提出一個多動作維護策略。該策略主要是在每一個偵測時間，依當時之系統狀態，在多動作集中選定最佳維護動作，並選擇下一個偵測點。文中假設：(1)在每個偵測時間，皆有多個維護動作可供選擇，(2)每一個選定之維護動作皆為“最小維護”，(3)偵測時間與維護時間皆可忽略。最後；利用出租影印機為例，說明該租賃系統如何依本策略進行維護。結果顯示，當該系統採用本策略後，其總成本與總操作成本可分別減少11.5%與63.6%。

A maintenance policy is proposed herein for a leased system under irregular inspection. Such policy is mainly to determine the maintenance action optimally at each inspection time and also to determine the next inspection time based on the current system conditions. Such policy holds by considering that: (1) multiple maintenance actions can be chosen at each inspection time; (2) each maintenance action taken is regarded as a ”minimal repair”, and (3) the times spent on inspection and maintenance action are ignored. A numerical example is presented to illustrate how such policy can be carried out for the leased photocopier system in practical. The results illustrate that the total cost and the total operating cost of the leased system under such policy can save 11.5% and 63.6% respectively.
