The problem is to determine the optimal replacement policy ( N , T )? such that the long-run expected cost per unit time is minimized.
利用几何过程，以系统大修次数N和大修时间间隔T为更换策略，选择最优策略（ N ， T）使系统经长期运行单位时间的期望费用最小。
An optimal replacement policy for series repairable system is studied assuming that the component after repair is not "as good as new" by using the geometric process model.
在假定故障部件不能“修复如新”的条件下，基于几何过程模型研究可修串联系统的最优更换策略。
