6.1 Introduction
Instantaneous availability models of typical repairable systems with infinite time
restrained are established in Chapter 4. en, in Chapter 5, it was proven that
the instantaneous availability A(k) of such systems are all gradually convergent to
steady-state availability A; that is,
, which indicates that when the
time (t) reaches a certain moment, the instantaneous availability will stably stay
in a very small range of nearby steady-state availability. However, the convergency
cannot ensure that the instantaneous availabi ...
