说明：  关于进程的调度算法 实验设计： （1）设计一个有N个进程共行的进程调度程序。每个进程由一个进程控制块 PCB表示。进程控制块包括以下信息：进程名，进程优先数，进程需要运行的时间，占用CPU的时间以及进程的状态等。 （2）本调度程序用优先数调度算法。 （3）编写程序并调试运行。
(on the process of scheduling algorithm Experimental Design : (1) design a process of a total of N line in the process scheduler. Every process from a process control block PCB said. Process control block include the following information : process, and several priority process, the process needs to run the time, CPU time and the process of status. (2) The scheduler with a few priority scheduling algorithm. (3) Prepare and commissioning procedures.)
