考虑专家偏好关联的群决策方法及其应用

通过分析群决策过程,提出使用模糊测度描述专家偏好之间可能存在的关联关系,并给出了一种考虑专家偏好关联的群决策方法.该方法从参评专家知识结构的相似性及判断结果的相似性出发,通过计算得到相应的2-可加模糊测度来描述专家的重要程度,并使用Choquet积分将多个专家的偏好信息聚合为群体的判断结果.最后,通过一个潜艇装备论证的例子验证了所提出方法的可行性和合理性.

A Group Decision Making Method and Application with Interactions among Experts’ references

By analyzing group decision making processes, it is proposed that there may be some interactions among
experts’ preferences which can be described by fuzzy measures, and a group decision making method with interactions among experts’ preferences is proposed. The method is based on the resemblance degree between the experts’ knowledge and between the experts’ comparison matrices, and the 2-additive fuzzy measures are calculated to represent the importance of experts. Choquet integral is used as the aggregation operators to obtain group’s preference. Finally, an example of naval submarine demonstration is given to show the feasibility and rationality of the proposed method.
