| 摘 要： | 本文阐述了专家系统中的不确定性及其产生原因.在分析各种不精确推理方法的基础上,指出了它们存在的问题与不足,由此引入了模糊事件的概率定义,并将模糊事件的概率引入多种不精确推理方法之中而对这些推理方法进行了扩展,使其能处理随机性与模糊性并存的不确定性问题.最后,本文吸取各种不精确推理方法的优点,从实用的角度出发,提出了模糊确定性理论作为一种新的不精确推理方法.文中对该方法进行了详细而全面的讨论.

| Abstract: | In this paper, the uncertainty in experts system and its causes are described and discussed. Several uncertain reasoning methods are analyzed and their problems are pointed out. The probability for fuzzy events is discussed and is drawn into several uncertain reasoning methods. So, these methods are expanded so that not only randomness but also fuzzy uncertainty are processed. Last, the fuzzy certainty theory is proposed and is discussed in detail in the paper. |
