在基于具有某种程度的不一致性的知识进行推理的过程中，为了消除知识的不一致性，只能将这些知识看成假说，并通过对假说进行修正以重新获得一个一致的假说．文中基于布尔算子模糊逻辑，给出了一种新的假说修正方法，这种方法能够在一定程度上更多地保留被修正知识的合理成分，以便在以后有机会得到恢复． In reasoning based on knowledge with a certain degree of inconsistency, in order to eliminate the inconsistency of knowledge, the knowledge can only be regarded as a hypothesis, and the hypothesis can be corrected to regain a consistent hypothesis. In this paper, based on the Boolean operator fuzzy logic, a new hypothesis correction method is given. This method can retain more reasonable ingredients of the corrected knowledge to a certain extent so as to have a chance to be recovered later.
