摘要
在可修系统总体的故障率函数的基础上,针对总体中的系统个体,提出一种新的故障率模型,文中结合实例给出详细运算过程。理论推导和实际应用表明,这种故障率模型能够准确、有效地描述系统个体在其寿命周期任意时刻的可靠性状态,对于该系统个体的可靠性预测和维修策略的制定具有重要的指导意义。
Based on the failure rate function of repairable system collectivity,a new failure rate model that focuses on system unit is presented by this paper,and an example is used to show the operation process.Both the theory and application show that this model could precisely describe the reliability state of system unit in any time of its life time.More over,it has great value in reliability predication and forming maintenance strategy.
