在决策过程中,经常有多个决策者一起共同决策,由于获取的信息有限,决策者给出的决策效果值并不是精确数而是区间灰数,针对这种情况,本文提出了一种灰色群决策方法。为将不同专家意见集结后得到一致性的结果,利用灰色关联分析的方法对专家进行赋权,建立了基于关联度的灰色群决策模型。最后通过实例分析,得出此方法计算简单且各方案之间差异较大,说明了模型的科学性、有效性和实用性。
In the decision-making process, many decision-makers often make joint decisions together. Due to the limited information obtained, the decision-making effect value given by decision-makers is not the exact number but the interval gray number. In view of this situation, Group decision-making method. In order to get the consistency of different expert opinions, the gray relational analysis method is used to empower the experts, and a gray group decision model based on the degree of association is established. Finally, through the case study, the conclusion is drawn that the method is simple to calculate and the difference between the schemes is large, which shows the scientific, validity and practicability of the model.
