文摘针对当前仿真组件模型(SCM,Simulation Component Model)开发存在的问题,首先采用特定领域建模(DSM,Domain-Specific Modeling)理论,通过分析仿真组件的基本结构和特征,确定仿真组件元模型整体的各部分模块及其相互关系,然后提出一种基于特定领域建模的仿真组件的建模方法和仿真组件模型开发流程。利用VMSDK(Visual Studio Visualization and Modeling SDK)工具,构建了描述仿真组件领域建模语言(SCMML,Simulation Component Model Modeling language)的元模型。最后,通过建模实例,表明该方法可显著提高仿真组件的开发效率。
