摘　　要：针对复杂系统仿真中模型需要根据环境自适应改变,导致不同分辨率模型之间的一致性和并发性问题,该文提出了基于组件的多分辨率动态结构(CMDS)建模与仿真方法。该方法从高层统一控制系统动态结构变化,利用分辨率状态图实现系统仿真模型交互一致性,通过组件端口自适应技术达到系统仿真前后状态一致性。并在此基础上,设计了模型结构快速重构算法。最后以大系统变结构问题为例,表明CMDS能够充分利用不同分辨率模型的优势,依据具体的计算资源选择合适的分辨率模型,兼顾速度和精度。In complex system simulations, the models adaptively change in accordance with the outward environment, which can lead to consistency and concurrency problems. A component-based multi resolution dynamic structure （CMDS） modeling and simulation approach was developed to improve these simulations. The model changes the structure from a high-level unified control model to a resolution state chart to achieve consistency with syntax consistency through port adaptive simulations. A algorithm is given to quickly reconstruct the CMDS system structure. Tests on a large simulation system with variable structures show that the CMDS approach can take advantage of models having different resolution and can quickly and accurately choose the appropriate model for the specific computing resources.
