1> SPF（Shortest Process First）：非抢占式，在进程调度时，根据就绪队列中排队的进程所预估的处理器使用时间，每次调度选择预估剩余处理器使用时间，最短的进程。 ；在作业调度时，称为短作业优先调度算法（Shortest Job First,SJF），根据外存队列中作业所要求的执行时间来调度进程，每次调度选择预
The FCFS, which stands for First Come First Serve Scheduling Algorithm, is a non-preemptive scheduling algorithm, which means that if a process once starts executing in the processor, then it cannot be preempted in between the processing. Thus, the concept of priority and urgency is not ...

In order to improve the system resource utilization rate and reduce the response time, a new task scheduling Priority Backfilling First Come First Serve (PB-FCFS) algorithm has been proposed. This algorithm combines backfilling, FCFS scheduling and adopts the dynamic priority strategy in task ...

It termed as First Come First Serve (FCFS) Scheduling. As its name implies, the process which arrives first in front of CPU for processing, then that process executed first. It is a non-preemptive scheduling algorithm which means in this priority of proc
Here is how an FCFS scheduling algorithm works. To begin, suppose there are three requests to process in the CPU’s queue: P1, P2, and P3. Assume P1 is a complex process that requires approximately 25 seconds, P2 a much simpler request that requires only 10 seconds of processing, and ...
