1、设置多个就绪队列，并给队列赋予不同的优先级数，第一个最高，依次递减。
2、赋予各个队列中进程执行时间片的大小，优先级越高的队列，时间片越小。
3、当一个新进程进入内存后，首先将其放入一个对列末尾，如果在一个时间片
结束时尚未完成，将其转入第二队列末尾。
4、当一个进程从一个对列移至第n个队列后，便在第n个队列中采用时间片轮转执行完。
5、仅当时间片空闲时，才调度第二个队列中的进程。
-1, setting a plurality of the ready queue, and queue priority given to different series, the first highest, followed by diminishing.
2, giving each queue process execution time sheet size, higher priority queue, time slice is small.
In 3, when a new process into the memory, first put it in a column end, if in a time slice
End of fashion is not complete, the turn into the second queue end.
In 4, when a process from one column to the N queue, then in the N queue using the time slice rotation executed.
In 5, only when time is free, only second the process queue scheduling.
