摘要
模糊数的排序法在决策及其它模糊应用系统的研究中起着非常重要的作用,众多学者提出了很多模糊数的排序方法,Cheng和Chu提出两种与模糊数中心有关的排序指标,但这两种方法都有明显的缺陷。本文构造了新的排序指标,能有效地实现各种模糊数的排序,最后用实例与前两种排序指标进行比较,体现出新指标的优越性。
Ranking Fuzzy numbers plays a very important role in decision making and some other fuzzy application systems. Many methods have been proposed to deal with ranking fuzzy numbers, Cheng and Chu proposed two different methods based on the centroids of fuzzy numbers respectively, but drawbacks are found in both indexes. To overcome the shortcomings, the paper proposed a new ranking method. The new method can effectively rank various fuzzy numbers. At last, this paper used some comparative exampies to illustrate the advantages of the proposed index.
