设计要求模拟实现一个的单道批处理系统环境下的作业调度程序。通过实现具体的作业调度算法，加深对该环境下的作业调度模型和实现过程的理解。 至少实现有三种的作业调度算法：先来先服务、短作业优先和响应比优先算法-Design requirements for the realization of a simulation of the single-channel system environment under a batch job scheduling procedures. Through the realization of specific job scheduling algorithm to enhance the environment of the job scheduling model and the realization of the process of understanding. Achieve at least three of the job scheduling algorithms: First Come First Served, short operating priorities and respond to priority algorithm than
