摘要
随着分布交互式仿真技术的发展,多分辨率建模成为建模与仿真的关键技术之一。提出了一种多分辨率模型系的概念,并分析了多分辨率模型系的重要性质。多分辨率模型系描述了同一实体的不同分辨率模型之间关系。在多分辨率模型系和DEVS描述理论的基础上提出了一种多分辨率模型系统的形式化描述规范MRMS,证明了该规范的重要性质,尤其是它的耦合封闭性。在MRMS的基础上,可以进一步深入开展多分辨率建模的理论和实现研究。
With the development of distributed interactive simulation, especially as the emergence of HLA, multi-resolution modeling （MRM） becomes one of the key technologies for advanced modeling and simulation. There is little research in the area of the theory of multi-resolution modeling, especially the formal description of MRM. A new concept named multi-resolution model family （MF） for the description of multi-resolution modeling is presented. A multi-resolution model family is defined as the set of different resolution models of the same entity. The description of MF includes two parts： models of different resolution and their relations. Based on this new concept and DEVS formalism, a new multi-resolution model system specification, named MRMS （Multi-Resolution Model system Specification） is presented. And some important properties of MRMS are proved, especially the closure of MRMS under coupling operation. MRMS provides a foundation and a powerful description tool for the research of MRM. Using this description, the theory and implementation of MRM can be further studied.
