摘要
基于行为建模的因果追溯方法是解决复杂仿真分析中因果关系追溯问题的一种思想。该思想依据仿真系统运行结果数据,重新构建描述因果关系的行为模型,并基于这些行为模型进行因果追溯。为了建立良好有效的行为模型支持追溯,首先介绍了因果关系的概念及其结构描述;然后将追溯划分为三个层次:系统表层、系统深层以及组合层,最后选取事件图行为模型为基本模型,按照这些层次分别对其进行扩展,从而获得不同层次的行为建模方法支持因果关系的描述和建模。
To solve trouble from causal tracing in complex simulation analysis, the causal tracing based on behavior modeling is put forward as a kind of ideas, This idea is to get simulation data from simulation system runs; rebuild behavior models to present behaviors and cause-and-effect relationships between them from these data, and trace based on these models, So it is very important to have an appropriate and effective behavior model, Firstly, the concept of causality and its structure were described, Then causal tracing was divided into three levels： system outside, system inside, and coupled system. At last, to model the causal relations, new models were established by extending a kind of general behavior model - Event Graphs to fit all level＇s tracing respectively.
