Scheduling (computing) - Wikipedia

Earliest deadline first (EDF) or least time to go is a dynamic scheduling algorithm used in real-time operating systems to place processes in a priority queue. Whenever a scheduling event occurs (a task finishes, new task is released, etc.), the queue will be searched for the process closest to its deadline, which will be the next to be scheduled for execution.

A functional law of the iterated logarithm for multi-class

Nov 19, 2020 · The model ((GI^B/GI)^K/1) is a single-server station queue serving K classes of jobs, (Kge 1).Customers of all classes arrive exogenously in batches, wait for service and leave the system after service completion. A FCFS service discipline is enforced among K classes, that is, customers in different batches are served in the order of arrival, and customers in the same batch are numbered

How does a concrete batch plant work | Operation of

BATCHING Batching is the process of measuring concrete mix ingre-dients by either mass or volume and introducing them into the mixer. To produce concrete of uniform quality, the ingredients must be measured accurately for each batch. Most specifications require that batching be done by mass rather than by volume (ASTM C 94 or AASHTO M 157).
