摘要
依据设备故障间隔期的概率分布，研究了设备故障次数的随机动态变化过程，建立了随机性分析的递归方程，并进一步研究了基于设备故障次数及其概率的最小费用周期更新模型。
In the paper, the stochastic process of the failure number is studied in following the line of modelling the dynamic equation for the failure number on the basis of the distribution of the failure time. A mathematical programming model is further proposed by minimzing the total cost for the replacement cycle. An example is used to illustrate its application of the approach.
