本程序用两种算法对五个进程进行调度，每个进程可有三个状态，并假设初始状态为就绪状态。初始优先数60。为了便于处理，程序中的运行时间以时间片为单位计算，各进程的优先数或轮转时间数以及进程需要运行的时间片数的初值均由用户给定。3）　　在优先数算法中，进程每执行一次，优先数减3，CPU时间片数加1，进程还需要的时间片数减1，在轮转算法中，采用固定时间片，时间片数为2，进程每执行1次，CPU时间片数加2，进程还需要的时间数减2，并排列到就绪队列的尾上。-This procedure using two algorithms for five scheduling process, each process can have three states, and assuming that the initial state to the ready state. The initial priority number 60. To facilitate processing, the program runs in time for the unit time slices, each time slice process priority number or rotation time and the number of processes that need to run the initial value by the number given by the user. 3) the priority number algorithm, the process Each time, priority number minus 3, CPU time slices plus one, the process needs time slices minus one, in the Round Robin, the fixed time slice, the time slice number 2 , each process is　d once, CPU time slices plus 2, the process needs time minus 2, and arranged into the tail of the ready queue.
