摘　　要：本文首先提出了模糊逻辑和多值逻辑的相似性,并从开关信号理论出发建立了多值逻辑阈运算和模糊函数取值区间有限等级的对应关系,进而提出了利用多值逻辑阈运算实现模糊逻辑函数分析与综合的算法,并用该算法对几个模糊逻辑函数实例进行了分析与综合。实例操作表明,该算法具有操作简单、规范、方便快捷的特点,是分析和综合模糊逻辑函数的有效方法。In this paper, similarities between fuzzy logic (FL) and multi-valued logic (MVL) are discussed. Relationship between the threshold operations of MVL and the finite classes of FL function is established based on switch-signal theory, and the algorithm for analyzing and synthesizing FL function using threshold operation of MVL is proposed. Using the algorithm, several FL functions are analyzed and synthesized. Experiment on selected functions show that features of the algorithm are simple, normative and straightforward. It is an effective method for analyzing and synthesizing FL functions.
