| 摘 要： | 确定Fuzzy数的序是一个重要的理论问题,有广泛的应用价值.CV指标法基于Fuzzy数概率分布的均值及方差对Fuzzy数进行定序,但在Fuzzy数概率分布的均值及方差的一些组合下存在失效问题,文中通过实例对此进行了分析,定义了综合Fuzzy数均值、方差及信息量的限位系数并给出了基于限位系数的Fuzzy数定序方法.

| Abstract: | To rank fuzzy numbers is an important theoretical problem, and it has extensive application value in realistic problems. The CV index of ranking fuzzy numbers is based on average value and deviation of fuzzy number , but it loses efficiency sometimes. We analyze the CV index of ranking fuzzy numbers and point out its existing shortcoming with examples in this paper. We define restriction coefficient of fuzzy number summing up average value and deviation and news in fuzzy number. At last we propose a method of ranking fuzzy numbers basing on restriction coefficient. |
