边坡治理方案选择的多属性多方案大群体决策方法

Multi-attribute Multi-scheme Large Group Decision-making Method about the Option of Slope Treatment

针对边坡治理决策是一个多属性群体决策问题,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。结合实例研究,说明该方法的有效性。

Since slope treatment decision-making belongs to multi-attribute group decision-making problems,a multi-scheme large group decision-making method based on multi-attribute characteristics is proposed.In the method of model and algorithm of single scheme large group preference are expanded into multi-scheme one to obtain the large group preference matrix firstly.Then,the ordering weights of every scheme are obtained by using the entropy weight method.Finally,the integrative evaluating value vectors of all schemes can be obtained by using the ordering weights and the large group preference matrix.The integrative ordering results for all the schemes are obtained through the integrative evaluating value in the vector.A case study is given to illustrate the effectiveness of the method.
