[OS Develop] OS5 DL : 0: 程序开始运行时选择调度算法，创建进程时输入进程所需服务时间以及到达时间。根据当前所设定调度算法，连续调度所有进程，并计算每个进程的周转时间和带权周转时间、所有进程的平均周转时间和平均带权周转时间。调度时应适当输出调度过程中各进程状态队列的变化情况以及进程的已执行时间、还需服务时间（针对时间片轮转算法）。-Routine is executed choice when scheduling algorithm, create process input process required service time and time of arrival. According to the current set scheduling algorithm, continuous scheduling all processes, and calculating each process cycle time and weighted turnover time, all process of the average turnover time and average weighted turnover time. Scheduling should appropriate output in the process of scheduling the process status queue changes and process already execution time, still need to service time (according to time slice rotary algorithm).
