Adaptive Modeling and Simulation of Dynamic Data Driven Application System

动态数据驱动应用系统(DDDAS)是一能够将实验或测量数据与仿真紧密结合在一起的新型研究模式,是未来仿真应用的发展方向之一。本文简述了DDDAS的产生动机和发展现状,分析了DDDAS的概念与开展DDDAS相关研究的现实意义。指出了仿真在DDDAS中的重要性,并从应用、算法和系统结构三个层次详细讨论了DDDAS仿真的适应性这一核心研究问题。在此基础上,重点讨论了DDDAS建模与仿真的研究内容,以及利用先进并行与分布式仿真技术实现DDDAS建模与仿真环境所需解决的关键问题。对几个典型的DDDAS应用进行了介绍,并对DDDAS仿真的军事应用前景进行了分析。

Dynamic Data Driven Application System (DDDAS) is a new research paradigm which can entail the ability to incorporate dynamically data into an executing application simulation, and in reverse, the ability of applications to dynamically steer measurement processes. The motivation, concept and state-of-the-art of DDDAS were introduced at first. Then, the importance of simulation in DDDAS was discussed, and the core adaptabilities of DDDAS simulation were detailedly analyzed from three levels: application level, algorithm level and system structure level. Based on these analyses, the research content of M&S in DDDAS and the main problems when realizing DDDAS M&S environment in parallel and distributed simulation environments were proposed. Typical applications of DDDAS paradigm and especially its application foreground in military simulation were also discussed.
