The main issues addressed are uncertain knowledge representation and approximate reasoning based on fuzzy set theory.

本文主要探讨了基于模糊集合理论的不确定知识表示和近似推理方法。

Fuzzy sets and fuzzy logic are important mathematical tools for processing uncertain and vague information, which has been widely applied to approximate reasoning and so on.

模糊集与模糊逻辑是处理大量存在的不确定性与模糊性信息的重要数学工具，在近似推理等领域有着广泛的应用。

When fuzzy production rules are used in approximate reasoning, there are interaction influences on rules that have the same consequent but different antecedent.

当模糊产生式规则应用在近似推理过程中时，前件相同而后件不同的模糊规则之间往往存在交互影响。
