摘要
将Chen的效用指标和模糊数的期望、方差结合起来,综合各自的优点,提出一种多指标模糊数排序方法.数值计算表明该方法在一定程度上克服了某些常用排序方法存在的缺点,具有较高的分辨率及较好的合理性.
This paper combines the utility index of Chen,expectation and standard deviation,making use of their advantages,proposes a method for ranking fuzzy numbers with multiple indices.Enough numerical examples indicate that the approach overcomes some defaults to some extent and possesses better efficiency of resolution and reasonability.
