一种基于权向量的组合赋值法求群权向量的方法

Way to Calculate Group Weight Based on Weights Combination Assigning Method

在群体决策中,决策群体中每个成员对一组可行的备选方案有不同的偏好次序且在确定指标权重时,随意性较大,这样对最终的方案就会作出不同的决策。运用多目标权系数的组合权向量,解决有限方案多目标群决策如何由各个决策者的偏好形成群的偏好,使决策客观、真实、有效,并用事例说明了其可行性。

In the course of group decision-making,each member of the group will keep different preference sequence for a group of feasible alternative projects,and he may fix on weights of index at random,so the ultimate result of decision-making is various.Combination weights of multiobjective weights are used to solve how to shape the groups' preference from the decision makers' preference for multiobjective group decision making with finite alternatives in this paper.This method makes sure that decision making is more objective,real and efficient.And calculating results show that the method is feasible through examples.
