研究了一种具有预防性维修的几何过程维修模型。采用一个维护策略（T，N），当系统发生故障或其运行时间达到T时，将对其进行修复，以先发生的为准，并且在第N次故障后，系统将被一个新的相同的系统替换。确定单位时间的长期平均成本。一个最优策略（T *,N *）可以用数值方法或解析方法确定，以使平均成本最小化。研究了一类新的考虑预防性维修效果的寿命分布，并将其应用于确定最优策略（T∗,N∗）。
In this paper, a geometric process maintenance model with preventive repair is studied. A maintenance policy (T,N) is applied by which the system will be repaired whenever it fails or its operating time reaches T whichever occurs first, and the system will be replaced by a new and identical one following the Nth failure. The long-run average cost per unit time is determined. An optimal policy (T∗,N∗) could be determined numerically or analytically for minimizing the average cost. A new class of lifetime distribution which takes into account the effect of preventive repair is studied that is applied to determine the optimal policy (T∗,N∗).
