Guaranteed scheduling is necessary for hard real time systems, because each process of them must meet their deadline, or a serious consequence will result.
有保证的调度对硬实时系统是必须的，这是因为系统中每个进程必须满足它们的截止时间，否则后果不堪设想。
In order to achieve this, scheduling models should be set up for hard real-time CORBA systems with static priority and periodic tasks.
为了更好地定量分析可预测性，需要为以固定优先级方式调度的、周期性任务的硬实时CORBA系统建模。
The hard periodic task and soft aperiodic task are two basic types of real-time task; their hybrid scheduling is an important part of real-time research.
硬实时周期任务和软实时非周期任务是实时系统中两种基本的任务类型，它们的混合调度问题是实时研究的重点之一。
