基于结构元理论的折衷型决策方法

Fuzzy compromised decision-making method based on the structured element

根据折衷型决策方法的原理,提出了基于结构元理论的模糊折衷型决策方法,共有两种模式:一种是先加权,后综合的模式,另一种是先综合,后加权的模式。借助传统模糊多属性决策中的一个实例,运用这两种算法进行了决策,得出了与传统决策方法相同的结论,证明这两种算法的可靠性,同时与传统的决策算法相比,本算法不仅易于理解,而且计算的速度也远比传统算法快。

The compromised decision-making method is one of most commonly used methods in the classical decision-making. According to the principle of this method, the authors put forward fuzzy compromised decision-making method based on the structured element theory. It has two kinds of patterns, one is weighting first and synthesizing later, the other is synthesizing first and weighting later. Making use of an example in traditional fuzzy multiattribute decision-making, the authors utilize these two methods to carry out the decision-making, and draw the same conclusion with the traditional decision-making methods, and that proves the high reliability of these two methods. Compared with the traditional decision-making methods,these two methods are easy to understand,and the operation speed is much quicker than that of the traditional methods.
