面向角色方法在工作流仿真中的应用研究

摘要

随着工作流的发展,工作流建模技术已经成为了一个重要的课题.介绍了面向角色的建模方法,以及建模仿真平台PtolemyⅡ,利用该平台的面向角色的建模思想,采用层次异构的思想组合各类组件来实现工作流建模仿真工作.同时对实际工作流模型案例进行了分析,采用面向角色的建模思想,在PtolemyⅡ平台上完成了建模设计,仿真结果与模型中的计算结果进行了对比,得出二者的结果基本一致,解决了工作流仿真中遇到的并发性问题.%With the development of workflow,its modeling techonology has become an important subject in different domains. Here, the actor-oriented modeling method and Ptolemy Ⅱ modeling and simulation platform are introduced. Based on the actor-oriented method and its hierarchical architecture,different components are used to achieve workflow modeling. At the same time, this paper analyzes a typical workflow example,designs the actor-oriented mode on Ptolemy II platform,compares simulated results with computing results in the model. They are almost the same. The concurrent problem occurring in the workflow simulation is also solved.
