> 中文摘要: 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.这种因果推理形式推广了Iwasaki因果推理方法.
Abstract: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 1wasaki'S causal reasoning method.
