摘要
定义模糊数的破碎度概念,并且结合模糊数的质心给出模糊数排序的新指标。这种排序指标能够在一定程度上克服已有排序方法的某些缺陷,并且有效地实现各种模糊数的排序;文章最后通过算例分析,证明基于质心和破碎度的模糊数排序是完全可行的。
Abstract：In this paper, the fragmentation of fuzzy numbers is defined. Based on the centroid and fragmentation of fuzzy numbers, paper proposes a new ranking method of fuzzy numbers which can overcome the shortcomings of some ranking method to some degree. At last, paper illustrates the practicability of the proposed method by the analysis of examples.
