关于模糊综合评判取大取小算法的研究

取小取小算法是模糊综合评判中的一种常用的方法。它具有一定的合理性,但是也存在着不合理的因素。当该算法失效时,可以使用其它一些算法来代替。本文通过对模糊综合评判的介绍,引入取大取小算法,并说明其合理性以及失效的情况,最后提出了改进的方法。

Study on The algorithm of "max-min"in the fuzzy synthetic judgement

The algorithm of "max-min" is a common method in the fuzzy synthetic judgement. It has certain rationality, but also exits irrational factors. When the algorithm fails, other algorithms can be used instead. Through the introduction of the fuzzy synthetic judgement, we introduce the algorithm of "max-min", and then analysis its rationality and failure. Finally, an improved method is proposed.
