Optimal Group Maintenance Policies with Continuous and Periodic Inspections
研究N台机器在随机故障下，连续或定期检查时的最优群组维护策略，证明控制限策略能最小化无限时间内的期望单位时间成本，并给出计算方法和定期检查策略的特征。
Optimum group maintenance policies for a set of N machines subjected to stochastic failures under continuous and periodic inspections are considered. Under very general conditions it is shown that a control limit policy minimizes the expected cost per unit time over an infinite horizon, when costs are incurred due to loss of production and repair only. It is also shown how to explicitly compute this control limit. When additional costs are incurred due to inspection, a characterization of an optimal periodic inspection/repair policy that minimizes the expected cost per unit time over an infinite horizon is given.
