摘要 在现实世界中,事物通常以不确定的形式存在,事物之间的关系也具有不确定性。另一方,人们从自然现象中总结出的规律或知识是经验的,或不确定的。因此,在推理判断和决策过中,均不可避免地涉及不确定的数据和知识的处理。现在。 The two uncertain reasoning models,the possibility theory and belief network,are first discussed in this paper. Next, a point-value causality reasoning model is established. In final, these three models are compared.
