Use α > 1 to model the random life time of an installation with an increasing failure rate. After running machines for a long time, wear-out failures occur, so that the probability of a failure within a time interval increases as the system ages. The life times that accrue most of the time are determined by the maximum of the density function (for α > 1) and are roughly defined by the values
5 b% M. `9 T# w5 q/ y+ z2 k请教一下:
4 j8 Z! T2 d$ N- n" M如果故障中间隔 设置为α > 1 的Weibull 分布,设备的故障率会随着时间推移增加,比如最开始是a0,过段时间变成了1.4*a0,8 K: L6 {7 N9 B/ y
9 }) w2 u) x5 b那么我要仿真在某个时间点想要这个故障间隔分布重新回到a0,应该如何操作? |
