中文摘要：
多属性多方案大群体决策问题广泛存在于网络环境中，将单方案大群体决策方法推广到基于多属性的多方案大群体决策中，由此获得大群体偏好矩阵．利用熵权法获得各个属性权重向量．将各个属性权重向量和大群体偏好矩阵进行合成，获得各个方案的综合评价值向量，由该向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．最后通过一个算例说明了方法的有效性，
英文摘要：
The problem of multi-attributes and multi-schemes large group decision making extensively exists in network environment. In the first, this paper expands the method of single scheme large group decision into the multi-attributes and multi-schemes large group decision making, and obtains a large group preference matrix. Then, a weight vector of all the attributes is obtained by using the entropy weight method. By combining the weight vector of all the attributes and the large group preference matrix, an integration evaluation value vector of all the schemes is obtained. From the integration evaluation values in this vector, the ordering result of each scheme is got. The methood solves the problem of multi-attributes and multi-schemes large group decision making better. Finally, a calculation example explains the validity of the method.
