Adding a blocking term \( B \) to a task's analysis is done by

  • A.adding it to the utilisation of the whole set
  • B.multiplying the response time by one plus \( B \)
  • C.adding it to the task's own execution time
  • D.subtracting it from the task's deadline

Answer: C

Treating the blocking as though it were part of the task's own demand keeps the recurrence in its familiar form and is conservative. A task that becomes unschedulable only when the blocking is included points at the shared resource as the thing to redesign.
