摘要
This paper presents a generalized model for determining minimum cost preventive maintenance schedules for a maintained reliability system. Through balancing the cost of system failure during operation against the cost of planned maintenance, an optimal policy is established which minimizes the expected cost rate. A simple equation to determine the optimal period between maintenances for a system with the known failure distribution is acquired, and the calculation for the system with Gamma failure distribution is given.
提出了一种寻求可修复系统的最佳预防性维修周期的方法，该方法是结合系统的失效损失费和维修费用，根据使系统单位有效使用时间费用均值最小的原则建立的。在系统的失效分布已知的情况下，推导出计算最佳维修周期的简单公式。针对失效时间为伽码分布的系统。
