Abstract: For the integration issues of subgroup in the process of group evaluation, this paper proposes a chain evaluation mechanism based on information entropy theory. Firstly, this paper divides evaluation subjects and objects into subgroups in order to avoid the negative impact of evaluation one by one. Secondly, to improve the consensus degree of group evaluation, this paper uses evaluation information of chain-relationship experts to amend the inconsistent scores and to adjust the differences in average and standard deviation between subgroups. At the same time, filtering evaluation information according to the theory of information entropy can effectively avoid the effect of individual on overall. Finally, a numerical example shows the feasibility and necessity for the proposed method.
