在采用多道程序设计的系统中，往往有若干个进程同时处于就绪状态。当就绪进程个数大于处理器数时，就必须依照某种策略来决定哪些进程优先占用处理器。本实验模拟在单处理器情况下的处理器调度，帮助学生加深了解处理器调度的工作,The introduction of multi-channel programming system, often at the same time there are a number of processes in a state of readiness. When the process in place when the number is greater than the number of processors, a strategy must be in accordance with the process of priority to determine which processor occupancy. Simulation of this experiment in the case of single processor scheduling processor to help students gain a better understanding of the work of processor scheduling
