  2. Shortest job next - Wikipedia

    en.wikipedia.org/wiki/Shortest_job_next

    Shortest job next being executed. Shortest job next (SJN), also known as shortest job first (SJF) or shortest process next (SPN), is a scheduling policy that selects for execution the waiting process with the smallest execution time. [1] SJN is a non-preemptive algorithm. Shortest remaining time is a preemptive variant of SJN.

  3. Shortest remaining time - Wikipedia

    en.wikipedia.org/wiki/Shortest_remaining_time

    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 ...

  4. Uniform-machines scheduling - Wikipedia

    en.wikipedia.org/wiki/Uniform-machines_scheduling

    The SPT algorithm (Shortest Processing Time First), sorts the jobs by their length, shortest first, and then assigns them to the processor with the earliest end time so far. It runs in time O( n log n ), and minimizes the average completion time on identical machines, [ 1 ] P|| ∑ C i {\displaystyle \sum C_{i}} .

  5. Queueing theory - Wikipedia

    en.wikipedia.org/wiki/Queueing_theory

    Preemptive shortest job first The next job to be served is the one with the smallest original size. [25] Shortest remaining processing time The next job to serve is the one with the smallest remaining processing requirement. [26] Service facility. Single server: customers line up and there is only one server

  6. Flow-shop scheduling - Wikipedia

    en.wikipedia.org/wiki/Flow-shop_scheduling

    Flow Shop Ordonnancement. Flow-shop scheduling is an optimization problem in computer science and operations research.It is a variant of optimal job scheduling.In a general job-scheduling problem, we are given n jobs J 1, J 2, ..., J n of varying processing times, which need to be scheduled on m machines with varying processing power, while trying to minimize the makespan – the total length ...

  7. Single-machine scheduling - Wikipedia

    en.wikipedia.org/wiki/Single-machine_scheduling

    Single-machine scheduling or single-resource scheduling or Dhinchak Pooja is an optimization problem in computer science and operations research.We are given n jobs J 1, J 2, ..., J n of varying processing times, which need to be scheduled on a single machine, in a way that optimizes a certain objective, such as the throughput.

  8. Longest-processing-time-first scheduling - Wikipedia

    en.wikipedia.org/wiki/Longest-processing-time...

    Order the jobs by descending order of their processing-time, such that the job with the longest processing time is first. Schedule each job in this sequence into a machine in which the current load (= total processing-time of scheduled jobs) is smallest. Step 2 of the algorithm is essentially the list-scheduling (LS) algorithm. The difference ...

  9. Input queue - Wikipedia

    en.wikipedia.org/wiki/Input_queue

    The shortest remaining time method tries to predict the processing time of developments and places them into the queue from the smallest to largest processing time. This method estimates and predicts based on prior history records. In term, its performance is not stable but better improves process waiting time than First-Come, First-Served.
