采用静态优先数的方法，编写一进程调度程序模拟程序，进程状态为就绪、运行、阻塞三种。模拟程序只对你所设置的“虚拟PCB”进行相应的调度模拟操作，即每发生“调度”时，显示出当前“PCB名字”、优先数、运行时间等，而不需要对系统中真正的PCB等数据进行修改-priority number using the static method, the preparation process of scheduling a process simulation program, the process in place for the state, running, blocking three. Simulation program only right you have set up a "virtual PCB" accordingly scheduling simulation operation, that is, each occurrence "Dispatch" shows that the current "PCB name" priority number, running time, without the need for a real system, such as PCB data changes
