首先介绍了几种基于信息特征(如优先级、长度、信息在系统总的占用时间等)的调度算法。

First, we introduce several general algorithms, which are scheduled based on the characteristic of information, such as priority, length, and time of information in system.

但由于装料、卸料、起动等操作占用时间较多，因此设备利用率低，生产效率也不高。

But because the loading, unloading, starting operation takes more time, so the equipment utilization rate is low, the production efficiency is not high.
