摘要
针对定性推理在有冲突情况下进行传播时所存在的问题，本文提出了一种因果关系形式，引入了“时间”和“效果”概念，给出了因果推理过程：先建立因果关系图，再传播原因变量的行为，并应用定性代数方法来处理冲突问题．
It is known that existed causal reasoning methods will have problems to propagate the causal behaviors when there are some conflicts. To solve this problem, the authors provide a causal relation formulation, which introduces the concepts of ‘time’ and ‘effect’. Then a process for causal reasoning is provided: constructs the causal relation graph, then propagates the causal behaviors of the reason variables (exogenous variables), and uses qualitative algebra to solve conflicting cases. It is an extension of Iwasaki's causal reasoning method.
