多分辨率仿真中一致性问题研究

RESEARCH ON CONSISTENCY PROBLEM IN MULTI-RESOLUTION SIMULATIONS

在多分辨率仿真中 ,当不同级别分辨率实体交互时会出现一致性问题 .它的产生是由于建模人员还没有找到一种很好的方法 ,去描述同一实体在多个分辨率级别间的相互关系而导致的 .即使在同一分辨级别中也可能发生不一致性问题 .分析了目前建模方法存在的问题 ,提出了解决一致性问题的 CM方法 .CM方法主张使用多分辨率实体 (MRE)的概念来替代聚合实体 (AE)和解聚实体 (DE) ,以一致的方式在指定的分辨率级别描述被仿真的对象 ,当有请求时 ,及时提供任意级别的属性绑定 .建立了映射函数和一致性模型 ,较好地解决了属性集数据的识别。

Since modeling workers have not identified an effective method to describe the correlations of the same entity among multi level of resolutions, consistency problem may occur when entities at multi level of resolution interact with each other in multi resolution simulations. It may occur even at the same level of resolution. Based on the analysis of problems in current modeling methods, a CM method is offered to solve the consistency problem. The CM method uses the concept of MRE to replace AE and DE, describes objects that are being simulated at designated resolution level in a consistent way, provides attribute bindings at any level at request, and establishes two mapping functions and a model of consistency. In this way, it solves the key problems of identification of attribute data set, temporal inconsistency, and mapping inconsistency.
