通过网页展示几种进程调度算法的流程1.先来先服务调度算法（FCFS）:就是按照各个作业进入系统的自然次序来调度作业。这种调度算法的优点是实现简单，公平。其缺点是没有考虑到系统中各种资源的综合使用情况，往往使短作业的用户不满意，因为短作业等待处理的时间可能比实际运行时间长得多。

2.短作业优先调度算法(SPF): 就是优先调度并处理短作业，所谓短是指作业的运行时间短。而在作业未投入运行时，并不能知道它实际的运行时间的长短，因此需要用户在提交作业时同时提交作业运行时间的估计值。

3.最高响应比优先算法(HRN)：FCFS可能造成短作业用户不满，SPF可能使得长作业用户不满，于是提出HRN，选择响应比最高的作业运行。响应比=1+作业等待时间/作业处理时间。

4. 基于优先数调度算法(HPF)：每一个作业规定一个表示该作业优先级别的整数，当需要将新的作业由输入井调入内存处理时，优先选择优先数最高的作业。-Scheduling Algorithm page impressions through several process flow 1. FCFS scheduling algorithm (FCFS): is in accordance with the respective operating system into the natural order to schedule jobs. The advantage of this scheduling algorithm is simple and fair. The disadvantage is that the system does not consider the integrated use of various resources, users tend to make short work of dissatisfied because short jobs awaiting processing time may be longer than the actual running time. 2. short operating priority scheduling algorithm (SPF): scheduling and processing priority is short operation, the so-called short-time job involves running short. And when the job is not put into operation, it does not know the length of the actual running time, thus requiring the user to submit an estimate of the job run time when submitting jobs simultaneously. 3. The maximum response ratio first algorithm (HRN): FCFS could cause short operation user dissatisfaction, SPF may make long job user dissati
