针对状态随使用时间而恶化的连续运行维修设备，提出了一种马尔可夫模型。该模型包括劣化和泊松故障、最小维修、周期性最小维修和给定数量的最小维修后的主要维修。精确的递归算法计算设备的稳态概率。对于不同类型的停电，使用不同的成本率来定义成本函数。基于最小不可获得性或最小费用，得到了该模型的最优解。如果使用最佳维护间隔，则主要维护很少是有益的。如果维护策略基于维护之间的非最佳间隔，则定期的主要维护可以降低成本。>；
A Markov model for a continuously operating service device whose condition deteriorates with time in service is proposed. The model incorporates deterioration and Poisson failures, minimal repair, periodic minimal maintenance, and major maintenance after a given number of minimal maintenances. An exact recursive algorithm computes the steady-state probabilities of the device. A cost function is defined using different cost rates for the different types of outages. Based on minimal unavailability or minimal costs, optimal solutions of the model are derived. Major maintenance is seldom beneficial if optimal maintenance intervals are used. If a maintenance policy is based on nonoptical intervals between maintenances, periodic major maintenance can reduce costs. >
