针对一类评价信息不完全的多属性群决策问题中的群体判断的共识性进行研究,提出一种基于相容关系的群体共识达成方法.该方法不需进行群体共识度的计算,避免了评价信息不完全时直接计算群体共识度的困难;对于专家没有给出的评价信息,不需要进行评估和填充,避免了评估和填充缺夫值时所需进行的复杂计算.最后通过一个实例对所提出方法的有效性和实用性进行了说明.
A tolerance relation based consensus approach is proposed to solve multi-attribute group decision making consensus problems, in which the evaluation information is incomplete. In this consensus approach, the difficulty of calculating the group consensus degree is also avoided in multi-attribute group decision making with incomplete evaluation information. Moreover, the unknown information is not filled up, so the difficulty of calculating the unknown information is avoided for that the tolerance relation is constructed by the known evaluation information. Finally, a case study is given to illustrate the feasibility and effectiveness of the proposed method.
