摘    要:针对基于模糊逻辑的加权模糊推理,Chen Shy i-M ing提出了两种计算合取式前件整体真值的方法。由于所用模糊数算子的影响,两种方法的求取结果在准确性和合理性上都存在一定的缺陷。这种缺陷将直接影响推理的性能。因此,为改善这种缺陷,提高推理性能,本文提出了一种新的三角模糊数算子。它的应用可以提高推理的准确性和合理性。

关 键 词:加权模糊推理  模糊逻辑  三角模糊数运算

Abstract:While investigating the weighted fuzzy reasoning based on fuzzy logic,Chen Shyi-Ming has proposed two approaches to calculating the truth-value of a conjunctive antecedent for a fuzzy(production) rule.Due to the inappropriate operators selected in the process of calculation,the truth-(values) given by the two approaches are often found to have some defects in accuracy and reasonability. The defects of truth-values seriously downgrade the reasoning performance.In order to improve the(accuracy) of the truth-value and the reasonability of reasoning,this paper proposes a new operator for triangular fuzzy numbers and discusses its application to weighted fuzzy reasoning.The application of the new operator can lead to a more accurate and more reasonable reasoning conclusion.
Keywords:Weighted Fuzzy Reasoning  Fuzzy Logic  Operation of Triangular Fuzzy Numbers
