Under phase-type assumptions on the given amount of work and on the durations of interruptions, it is shown that the completion time of a task which is subject to interruptions has a phase-type distribution. This is shown for both the ‘repeat’ and the ‘resume’ alternatives. Asymptotic expressions are obtained for the tail probabilities.
