[0059] The part of the EMU to be calculated is the life of the parts of the "inner door". Taking the 2C type car as an example, there are n=32 parts whose type is "in-vehicle facility" and whose part is "inner door". An initial mileage t from the EMU 0 or an initial time t 0 Start to record the failure records of r=10 consecutive failures, the type is "in-vehicle facility", and the location is "internal door", and record the mileage or time t of each failure i , i=1, 2, 3,..., r; the sample value is determined by t i -t 0It is concluded that this sampling method is censored with a fixed number of replacements. It is also possible to obtain an initial mileage t from the EMU 0 or an initial time t 0 Start to record the mileage or time t of the EMU when all fault data occurs within the time t i , and also assume that at t 0 In the interval from t to t, a total of r failures occurred (t i i -t 0 It is obtained that this sampling method is censored with replacement timing....
