研究了不确定条件下设施老化过程中的最优维修与检测策略。假设在连续状态下定义的设施的状况只能通过检查来观察。最优脉冲控制问题的制定，以找出最佳的检查和维修时间，以最小化预期的寿命周期成本，包括维修成本，用户的成本，和检查成本。通过求解二阶Fredholm积分方程，提出了基于状态观测的状态相关规则，以确定最优检修时机。本文最后用数值例子说明。
This paper focuses upon the optimal repair and inspection policies of infrastructure under uncertainty in the facility deterioration process. It is supposed that the condition of the facility, which is defined in continuous state, can only be observed by inspection. The optimal impulse control problem is formulated to find out the optimal timing for inspection and repairing so as to minimize the expected life-cycle costs, including the repairing cost, user's cost, and inspection cost. The state-dependent rules are presented to determine the optimal timing for inspection and repairing based upon the observation of condition state by solving the second-order Fredholm integral equation. The paper concludes with numerical examples, for illustration.
