模糊多属性决策的三种结构元方法

将结构元理论引入到模糊多属性决策中,按照经典多属性决策的乐观型准则、悲观型准则和乐观-悲观结合型准则,对应地建立了基于模糊结构元理论的模糊乐观型、模糊悲观型、模糊乐观-悲观结合型决策方法。借助一个实例,本文运用这三种算法进行了决策,得出了和传统决策算法一致的结论。本文提出的算法不仅易于理解,而且计算的速度也远比传统算法要快,对于进一步研究模糊多属性决策问题有很好的参考作用。

Three Kinds of Fuzzy Structured Element Methods in Fuzzy Multiattribute Decision Making

The main goal of this thesis is to introduce the structured element theory into fuzzy multiattribute decision making.According to optimistic,pessimistic,and optimistic-pessimistic union rules of classic multiattribute decision making,correspondingly we establish fuzzy optimistic,fuzzy pessimistic,and fuzzy optimistic-pessimistic union decision making methods based on fuzzy structured element theory.Making use of an example,we utilize these three methods to carry out the decision making,and draw the same conclusion with the traditional decision making methods.These three methods are easy to understand,and the operation speed is much quicker than that of the traditional ones,and they will have a further referential effect on doing research on fuzzy multiattribute decision making problems.
