针对硬实时系统工作流描述在活动间数据交互的关系、时间约束等方面的不足，研究硬实时系统的工作流建模技术。定义硬实时约束的工作流元模型，给出元模型的组成元素及其相互关系，对具有硬实时约束的相关元素进行说明；在此基础上，使用UML的profile机制，通过对UML建模元素的扩展定义一种硬实时约束的工作流描述语言，称为 HRT‐WDL （hard real‐time constrained workflow description language）；结合应用案例对HRT‐WDL的使用进行说明。

Workflow descriptions of hard real‐time systems lack time constraint on data transfer among activities and refinement of relationships between data and activities .Thereby ,a UML based workflow modeling technology of hard real‐time systems was proposed .A hard real‐time constrained workflow meta‐model was defined and the elements and their relationships in the meta‐model were clearly described ,especially the ones related to hard real‐time constraints .Using UML profile mechanism ,a hard real‐time constrained workflow description language ,named as HRT_WDL ,was defined by extending UML elements .A case study was conducted to explain the usage of HRT _WDL .
