（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）本调度程序用时间片轮转算法。

　　（3）编写程序并调试运行。

-(1) design a process, a total of N lines of the process scheduler. Each process consists of a process control block PCB said. Process control block include the following information: process name, process priority number, the process need to run time, CPU-time and process status. (2) use of the scheduler time slice rotation algorithm. (3) programming and commissioning.
