基于多参数的群决策方法

研究了多指标决策问题中，指标随着时间的变化，增加了一个时间维度，以进行更合理的综合排序，有效克服群决策方法中只考虑指标、方案二维排序问题的弊端．给出了三维标度下的群决策方法及具体步骤，并通过实例得出，把时间考虑进去能更有效地把近几年的数据进行分析，从而为决策者提供更全面的决策依据．

Group decision-making method based on the dimension of multi-parameters

In some cases of multi-attribute decision-making problems,the indexes always vary with time.By increasing the dimension of the problem more reasonable and better decision can be made and the disadvantage of considering only two dimensions of index and scheme can be effectively overcome.In the paper,the three-dimensional group decision-making method is proposed and detailed steps of the method are presented.In considering the time effect,with this method the data in recent years can be analyzed more efficiently in the illustrative examples,and will give overall reliance to decision-maker for making correct choosing.
