Abstract:
In this paper, we consider a system operating in a random external shock process. The underlying system performance is modelled by a quality (output) function which is decreasing due to degradation. Shocks affect the failure rate of the system directly and, at the same time, they additionally decrease the quality function. Expectations (unconditional and conditional on survival) and variability of this time-dependent quality function are analyzed.
