摘要

本篇研究為考慮小修復與不完美的預防維修的整合性存貨性模型在一個生產系統逐漸惡化的情況下.在以往的文獻中預防維修的情況大多為兩種,分別為完美預防維修與不完美預防維修.
完美預防維修的機率主要是根據上一次循環時間裡面不完美預防維修的次數來決定,在每一次失效發生時會產生不良品，不良品當中又有一定數量的不良品是可重工而一部分為無法重工，而這些無法重工的不良品將會導致缺貨，本篇研究同時考慮了可重工與不可重工兩個項目的成本,最後我們在數學模型中去求取供應商與零售商整合後的最佳總成本，在後面的章節也考慮了不同的失效機率並且求解.

This study examines the feasibility of using an integrated inventory model incorporating production programs and maintenance to model an imperfect process involving a deteriorating production system. Following production run period two preventive maintenances are performed, namely perfect preventive maintenance, and imperfect preventive maintenance.
The perfect preventive maintenance’s probability depends on the number of imperfect maintenance operations performed since the last renewal cycle.
Every time when failure occurs will produce defective products which have a certain number of the ability of rework and not to be rework, and those cannot rework will lead to shortages.
The model is shown to provide an optimal number of shipment and lower cost. We also build various special cases that consider failure rate, including weibull, geometric and learning effect. Finally a numerical example is presented.
