基于熵权的多属性大群体决策方法

针对传统的大群体决策方法只能处理单方案决策问题的缺陷,提出了一种基于多属性的多方案大群体决策方法。该方法首先将单方案大群体偏好模型与算法推广成多方案大群体偏好模型与算法,获得大群体偏好矩阵,然后利用熵权法获得各个方案的排序权重,最后利用各个方案的排序权重和大群体偏好矩阵获得各个方案的综合评价值矢量。通过该综合评价值矢量中的综合评价值得出各方案的综合排序结果,较好地解决了多属性多方案大群体决策问题。通过计算机仿真实验证明该方法的有效性。

Method of multi-attribute large group decision making based on entropy weight

Aiming at certain decision making methods can just deal with the single-scheme decision making problem,a multi-scheme large group decision making method based on multi-attribule characteristics is proposed.This method firstly expands the model and algorithm of single scheme large group preference into the multi-scheme to obtain the large group preference matrix.Then,the ordering weights of every scheme are obtained by using the entropy weight method.The integrative evaluating value vectors of all schemes can be obtained by using the ordering weights and the large group preference matrix.Finally,the integvative ovdering results for all the schemes are obtained through the integrative evaluating value in this vector,it resolves the problem of multi-attribute and multi-scheme large group decision making better.The validity of this method is proved through the computer emulation.
