| 摘 要： | 提出了权值法和修正权值法两种不确定性推理算法，与常用的几种方法相比，权值法根据各证据重要程度的不同，区别对待证据的可信度信息，同时充分利用每一条信息；修正权值法除了具有权值法的优点外，又区分了可信度分布的差异。运用修正权值法已成功建造了多个实用专家系统。

| Abstract: | This paper puts forward two kinds of non-accurate inference algorithms,weight method and revised weight method. While making full use of every certainty information,weight method assigns different weight to those information according to their importance. Revised weight method can distinguishes the distribution difference of certainty factors in addition to all the. advantages of weight method. |
