对MYCIN不精确推理模型的修正及应用

A Method for Improving the Certainty Factor Calculating Model in MYCIN and Application to Computer Reasoning

针对ＭＹＣＩＮ可信度计算方法的不足，本文提出了“模糊逻辑”和“非纯逻辑”两种修正方法，而且“非纯逻辑”还可表示“模糊逻辑”和传统的“纯逻辑”，因而更灵活、实用。但二者也存在推理效率降低的缺陷，所以本文最后还提出了改善推理效率的几个措施。

篒n view of the limitation of the certainty factor calculating model in MYCIN，this paper put forward two kinds of improving method─—fuzzy logic and unpure logic.When applied in reasoning，the unpure logic method is more flexible and more practical，for it can express the fuzzy logic and the traditional pure logic， Finally，Some measuresare given in this paper to improve the inference efficency when applying the two methodto the reasoning.
