关于威布尔分布

Amethysp

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

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？
