# Library prosa.model.task.absolute_deadline

Require Export prosa.model.task.concept.
Given relative task deadlines and a mapping from jobs to tasks, we provide the canonical definition of each job's absolute deadline, i.e., job_deadline, as the job's arrival time plus its task's relative deadline.
