system 2. Both systems have the same MLDT and completely the same distribution
for the service life and repair time to follow. But, as seen in Figure 8.15, different
combinations of α

can greatly change the instantaneous availability of
systems, especially the fluctuation of instantaneous availability at the preliminary
operation period. Refer to Table 8.7, Figures 8.9 through 8.11 for related param-
eters. erefore, it is believed that the availability amplitude, occurrence time of
minimum availability, and the adaptat ...
