摘要
给出了模糊数偏差的概念,并结合模糊数的质心以及决策者的偏好,提出了排序模糊数的新指标.运用该排序指标对模糊数排序,在一定程度上克服了已有一些排序方法的缺陷.最后通过算例进行比较分析,说明了该方法的可行性和有效性.
In this paper, the deviations of fuzzy numbers are defined. Based on the centroids and deviations of fuzzy numbers and the preference of decision makers, this paper proposes a new ranking method for fuzzy numbers, which can overcome the shortcomings of some ranking method to some degree. At last, this paper illustrates the advantages of the proposed method by analysis and comparison of examples.
