摘要
从正态分布的定义及实际意义出发,对通常所用的正态模糊集进行改进,构造了一个修正的正态模糊集;利用取大取小运算的一些运算性质,推导出当论域为实数域时,在修正的正态模糊集下一个与标准正态分布有关的新的格贴近度计算式.
By Ihe definition of normal density, improvement on the usual normal fuzzyset, were made, and a modified normal fuzzy-set is constructed. By use of the operational properties of max-min algorithm, the approach degree only related normal distribution for the real domain is deduced.
