摘要: 为通过部件组合维修提高维修效益,对采用状态维修的多部件系统,建立了部件状态随机劣化模型。采用幂指数函数建立以状态值为变量的可靠度函数,在考虑不完全维修、维修时间随机分布等因素的条件下,采用蒙特卡洛仿真方法建立了系统状态劣化过程模型。以单位寿命费用最小为优化目标,建立了多部件系统状态维修阈值的优化决策模型。案例分析结果表明,建立的状态维修决策优化模型能够显著降低维修费用、提高系统可用度,是适用且有效的。

Abstract: To promote the maintenance benefit by combined maintenance, for multi-component systems subjected to condition-based maintenance each component is supposed to endure independent gradual deterioration, and a stochastic deteriorate model is established. The exponential function is applied to set up the reliability functions taking condition parameters as variables. In consideration of imperfect maintenance and probability distribution of maintenance time, a Monte Carlo-based condition deteriorating simulation model of multi-component system is proposed. TA preventive maintenance threshold optimization model is constructed by taking the expected expenses per unit time as the optimization objective, and is verified by a case study. Key
