摘要
根据可靠性理论,建立不同的维修策略下可修复系统的失效模型。当系统零部件的概率是时间的函数时,用本模型可预测未来某一时刻对应维修策略下系统失效的概率,从而为制订合理的维修策略提供有效的依据。为使模型具有实用性,用事件树分析法对工业输水管道进行系统可靠性分析、定量计算,得出不同维修策略模型下系统失效的概率,有效地估计维修策略对系统的影响,并提出管道系统安全性的建议。
The failure models of reparable system under different repairing games are constructed according to the reliability theory. If the system accessories are the function of time, these models can be used to predict the failure possibility of the system for different repairing games at any given time in the future. They can be used effectively for the design of reasonable repairing games. To make the models more applicable, event tree analysis and quantitative calculation on industrial conduit pipes are carried out and the probabilities of the system for different repairing games are obtained. The effects of different repairing games on the system are estimated effectively, and the advice for ductwork safety improvement is presented.
