When jobs can have arbitrary release times, the problems are strongly NP-hard, by reduction from the problem with arbitrary deadlines. [15] When jobs can have one of two release times, either 0 or R, the problems are NP-complete. [15] Kubiak and van-de-Velde [16] studied makespan minimization when the fatigue starts only after a common due-date d.
In a service environment, a job order cannot be the equivalent to a work or service order where the job order records the location, date and time the service is carried out and the nature of service that was carried out, the work order does not. The type of personnel (e.g. job position) may also be listed on the job order.
Earliest deadline first (EDF) or least time to go is a dynamic priority scheduling algorithm used in real-time operating systems to place processes in a priority queue. Whenever a scheduling event occurs (task finishes, new task released, etc.) the queue will be searched for the process closest to its deadline.
