说明：  操作系统课程设计题目：进程调度模拟程序 设计要求：编写一个进程调度程序，允许多个进程共享进程调度程序。 进程调度算法：采用最高优先数优先的调度算法（即把处理机分配给优先数最高的进程）和先来先服务算法。
(Courses on operating system design topics: process scheduling simulator design requirements: the preparation of a process scheduler that allows multiple processes to share process scheduler. Process scheduling algorithm: the number of priority the highest priority scheduling algorithm (ie the number of processors allocated to the highest priority in the process), and first come first serve algorithm.)
