摘要
引进模糊数的四维表示,并据此给出一种新的排序方法,简化了模糊数特别是e-型模糊数的加减运算。
In this paper, four-dimensional representations and new ranking approaches of fuzzy numbers are presented. On the same time, simple operations of fuzzy-numbers, by which the addition and subtraction operations of e-type fuzzy numbers are well simplified, are also given.
