基于方案群体满意度的多属性群决策方法

为了在多属性群决策过程中，能够恰当体现不同决策者偏好的差异并进行偏好集结，定义了方案的群体评价正理想值和群体评价负理想值，构造了多属性群决策中衡量方案的一个新指标——方案群体满意度。在此基础上，根据主观给定的权重信息状况，分成无给定权重信息、给定权重限制条件、给定确切主观权重三种情形，并提出了相应的基于群体满意度的多属性群决策方法。最后，通过实例说明了所提方法的具体应用。

A Method Based on Group's Satisfaction Degree of Alternative for Multi-Attribute Group Decision-Making

To reflect and aggregate the individual preferences properly in the multi-attribute group decision-making processes,a new indicator for measuring decision alternatives i.e.group's satisfaction degree of alternative is first present based on the definition of group assessment ideal value of alternative and group assessment negative ideal value of alternative.According to the given weights information,the problems are divided into three conditions,namely condition of being not given weights information,condition of being given weights limitation and condition of being given certain subjective weights.Then the methods based on group's satisfaction degree for multi-attribute group decision-making are introduced respectively in the three conditions.Finally,a numerical example is given to illustrate the application of the method.
