【摘要】 分布交互仿真系统技术复杂、开发周期长。如何使仿真技术平台对仿真应用开发人员透明;如何重用已有的仿真实验框架和模型。这是分布交互仿真系统开发亟待解决的两个问题。MDA方法是解决以上两个问题的一种思路和途径。本文立足于仿真模型转换相关的重要技术MDA和组件开发方法,讨论了MDA的元建模和模型转换技术,分析了现有模型转换方法和工具以及目前MDA方法在分布交互仿真中的应用现状,提出了改进的方向。根据分布交互仿真的应用需求,分析了分布交互仿真中应用MDA模型转换的现实途径,提出了一个基于模型驱动架构(MDA)的分布交互仿真模型转换框架(DSMTF),以此作为仿真模型转换的设计基础,设计了仿真模型转换的元模型、转换规则和转换框架的体系结构,该框架可以通过扩展转换规则库支持不同的仿真标准。以HLA/RTI为例研究了DSMTF中模型转换的方法和步骤,提出了HLA仿真元模型并据此定义了相应的规则库。结合EMP(Eclipse Modeling Project)实现了该框架,通过一个分布交互仿真系统的开发,实现了仿真模型的自动转换,在一个仿真模拟应用开发中获得了成功的应用。更多还原

【Abstract】 Distributed Interactive Simulation system has a long development cycle and its technology is very complex. The development of this system needs to address two issues, one is how to make the simulation technology platform transparent for the simulation application developers, the other is how to reuse the existing framework and simulation models in different simulation platform. Model Driven Achitecture(MDA) is the way and idea to solve above two issues.In this paper, based on the simulation model transformation related technology, MDA and Component Based Software Development(CBSD).We focus on the meta modeling and model transformation technology. After the analysis of exsiting model transformation methods and tools, as well as the current research status of MDA approach in the Distributed Interactive Simulation Application, we put foward an improved direction. According to the application requirements of Distributed Interactive Simulation, a realistic way of MDA model transformation in domain of Simulation is set up, a distributed interactive simulation model transformation framework (DSMTF) based on model driven architecture (MDA) is proposed. Take DSMTF as design basis of simulaion model transformation, the meta-model and transformation rule of simulation model, and the achitecture of framework is designed. The framework can be adapted to different simulation standard by replacing the transformation rules. The transformation methods and realization in HLA/RTI of DSMTF is introduced in detail , a design in meta model and model transformation rules of model transformation framework is carried out. We realize this framework combined with EMP(Eclipse Modeling Project). The rules base on proposed meta-model of HLA/RTI are used in the automatic transformation of simulaiton model. The framework is applied successfully in a simulation application development.更多还原
