摘　　要：简要回顾实时系统的开发现状,对实时系统可调度性相关理论进行探讨.提出一种基于实时统一建模语言对实时系统可调度性进行分析的方法.通过将系统RT-UML模型中实时任务的相关数量信息提取出来,在相应分析工具中进行可调度性分析,分析结果自动反馈到模型中去,实现了对实时系统可调度性进行系统实现前的离线分析.The actuality of real-time system development is reviewed and the correlative theories for real-time system schedulability analysis are discussed. One method for real-time system sehedulability analysis is prosontod basod on real-time unified modeling language. We have realized the off-line real-time schedulability analysis before system implementation. Through distilling the correlative quantities information of real-time task in the system real-time UML models and analysing by the corresponding tool, the result can be fed back to the models automatically.

关 键 词：实时统一建模语言 可调度性分析 实时系统
