Discretionary priority discipline: A reasonable compromise between preemptive and nonpreemptive disciplines. (English) Zbl 0866.60080

Summary: Discretionary priority queueing discipline models are intermediate between traditional preemptive and nonpreemptive disciplines and suggest some advantages over such models. A discretionary priority queueing discipline is considered for a deterministic service time model, and it is shown that the average system time is shorter than for the preemptive and nonpreemptive models.
