Shortest remaining time being executed. Shortest remaining time, also known as shortest remaining time first (SRTF), is a scheduling method that is a preemptive version of shortest job next scheduling. In this scheduling algorithm, the process with the smallest amount of time remaining until completion is selected to execute. Since the ...
The modified due date scheduling is a scheduling heuristic created in 1982 by Baker and Bertrand, [1] used to solve the NP-hard single machine total-weighted tardiness problem. This problem is centered around reducing the global tardiness of a list of tasks which are characterized by their processing time, due date and weight by re-ordering them.
One of the core ideas of evidence-based scheduling, that adds to the normal estimation practices, is the idea of including all time spent, regardless of relevance.. Most people, when estimating, measure the time they actually spend on a project – classic Time Accounting categories such as cited in McConnell's Software Project Survival Guide [1] do not allow for accounting for non-project ...
Specific names for the linear scheduling method have been adopted, such as: [1] Location-based scheduling (the preferred term in the book) Harmonograms; Line-of-balance; Flowline or flow line; Repetitive scheduling method; Vertical production method; Time-location matrix model; Time space scheduling method; Disturbance scheduling
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.
In manufacturing, the purpose of scheduling is to keep due dates of customers and then minimize the production time and costs, by telling a production facility when to make, with which staff, and on which equipment. Production scheduling aims to maximize the efficiency of the operation, utilize maximum resources available and reduce costs.

In the position-based aging model, the processing time of a job depends on the number of jobs processed before it, that is, on its position in the sequence. [ 17 ] In sum-of-processing-time-based aging model , the processing time of a job is a weakly-increasing function of the sum of normal (=unaffected by aging) processing times of the jobs ...
