【摘要】 在模糊数的实际应用和决策分析中,模糊数的排序起着非常重要的作用.许多学者提出了一些模糊数的排序方法,如基于模糊数的重心排序,基于模糊数的重心与原点的距离排序,基于模糊数的距离排序等方法.本文将赵娟2008年提出的排序指标D(A)进行化简并记作D~*(■),然后根据D~*(■)的大小进行排序,对重心相同的模糊数再根据平均模糊度■(■)的大小进行排序.更多还原

【Abstract】 Ranking fuzzy numbers plays a very important role in the practical application and decision analysis of fuzzy numbers.Many scholars have proposed some ranking methods,such as ranking fuzzy numbers based on its centroid,ranking fuzzy numbers based on distance between its centroid and origin,ranking fuzzy numbers based on distance fuzzy numbers and so on.The paper simplified ranking index D(A) put forward by Zhao and be denoted by D~*(■) and ranked by the size of D~*(■),and then ranked fuzzy numbers with the same centroid according to the average ambiguity ■(■).更多还原
