| 摘 要： | 目前研究单机实时系统的调度算法文章大多只能调度单一类型的任务。本文在PKSA算法的基础上，建立了一种混合型实时容错模型，提出一种调度算法不仅可以调度有容错需求的周期任务，同时也能够调度无容错需求的周期任务和非周期非实时任务，实现了调度混合型任务的目的。

| Abstract: | Some fault-tolerant scheduling algorithm, studied for single processor real-time systems in the literatures, only can schedule single-type tasks, This paper presents a hybrid real-time fault-tolerant model, based on the PKSA algorithm, It proposes a improved algorithm which can schedules hybrid-type tasks including periodic tasks with and without fault-tolerance, and aperiodic tasks. |
