1)　　每一个进程有一个PCB，其内容可以根据具体情况设定。

2)　　可以在界面设定的互斥资源（包括两种：输入设备与输出设备）的数目

3)　　进程数、进入内存时间、要求服务时间可以在界面上进行设定

4)　　进程之间存在一定的同步与互斥关系，可以通过界面进行设定，其表示方法如下：

进程的服务时间由三段组成：I2C10O5（表示进程的服务时间由2个时间片的输入，10个时间片的计算，5个时间片的输出）

进程间的同步关系用一个段表示：W2，表示该进程先要等待P2进程执行结束后才可以运行

因此，进程间的同步与互斥关系、服务时间可以统一用四段表示为：I2C10O5W2

5)　　可以在运行中显示各进程的状态：就绪、阻塞、执行

6)　　采用可视化界面，可在进程调度过程中随时暂停调度，查看当前进程的状态以及相应的阻塞队列

7)　　具有一定的数据容错性-1) Each process has a PCB, its contents can be set depending on the circumstances.

2) may be in the number of interface settings mutex resources (including two types: the input device and output device)

3) the number of processes into the memory time, service time can be set on the interface

4) between processes, there are certain synchronization and mutual exclusion relationship can be set via the interface, which represents the method is as follows:

The service time of the process is comprised of three fields: I2C10O5 (the service time of the process from the input of the two time slice, the calculation of the 10 time slices, five time slices output)

Interprocess synchronization: W2, said that the process need to wait until after the end of the P2 process execution can run a segment

Therefore, inter-process synchronization and mutual exclusion relations, service time can be unified in four to: I2C10O5W2

5) can display the status of each process running: Ready, blocking, execut
