先来先服务算法（FCFS），短作业算法（SJF），高响应比算法（HRN）和高优先权优先算法是作业调度度总经常采用的，通过上述算法的模拟加深对作业控制块JCB的理解和作业调度过程的实现技巧。

-Algorithm (FCFS) first-come, first-served the short operating algorithm (SJF), high response first algorithm than the algorithm (HRN) and high-priority job scheduling degrees total is frequently used by the simulation of the above algorithm a better of job control block JCB understanding and realization of the job scheduling process skills.
