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.

Instance job_deadline_from_task_deadline (Job : JobType) (Task : TaskType)
`{TaskDeadline Task} `{JobArrival Job} `{JobTask Job Task} : JobDeadline Job :=
fun (j : Job) ⇒ job_arrival j + task_deadline (job_task j).
