Operational software availability measurement with two kinds of restoration actions
Koichi Tokuno, Shigeru Yamada · Journal of Quality in Maintenance Engineering · 1998
This paper develops a plausible software availability model for operational use. In particular, we consider two kinds of restoration scenarios; one involves the debugging activity and the other does not involve the debugging activity. The time‐dependent behavior of the software system during the operation phase is described by a Markov process. Several stochastic quantities for software availability measurement are derived from this model. Finally, numerical examples are shown to illustrate software availability analyses.
