摘要
在文献[1]中,通过用t模取代文献[2]中的取小算子,得出了模糊数的一种传递性排序方法。但这种方法要求模糊数满足的条件过于严格。本文旨在指出:1)该方法实质上是按最小的t模进行排序;2)当取最大的t模时,该方法仅对一类非常特殊的模糊数成立。
In paper[1] a transitive ordering method of fuzzy numbers is obtained by using t-norm to replace the rain operation in[2]. But this approach demand fuzzy numbers to satisfy some conditions which are too strict. In this paper we point out that 1) the method in (1) uses the minimum t-norm to rank fuzzy numbers in essence. 2) the method in [2] holds true only for a particular class of fuzzy numbers when the maximum t-norm is chosen.
