一、目的要求

　　用高级语言编写和调试一个或多个作业调度的模拟程序，以加深对作业调度算法的理解。



二、例题：为单道批处理系统设计一个作业调度程序。

　　由于在单道批处理系统中，作业一投入运行，它就占有计算机的一切资源直到作业完成为止，因此调度作业时不必考虑它所需要的资源是否得到满足，它所占用的 CPU时限等因素。

　　作业调度算法：采用先来先服务（FCFS）调度算法，即按作业提交的先后次序进行调度。总是首先调度在系统中等待时间最长的作业。

-First, the purpose of high-level language requires writing and debugging of one or more job scheduling simulation procedures in order to deepen their understanding of job scheduling algorithms. B, Example: In order to single-channel system, the design of a batch job scheduling procedures. Road as a result of a single batch system, the operation of a put into operation, it would occupy all the resources until the computer s operation has been completed, so no need to consider when scheduling operation of the resources it needs are met, it is occupied by factors such as CPU time limit. Scheduling Algorithm: The First Come First Served (FCFS) scheduling algorithm, that is, according to the order of operations submitted for scheduling. Scheduling is always first in the system waiting for the longest operations.
