Abstract: To make use of the social relationship between experts and the limited rationality of decision experts in group decision-making, the TODIM(TOmada de Decis?o Interativa Multicritério) multi-attribute group interactive decision-making method based on trust network was proposed. Firstly, according to the number of discussions, in each expert discussion, each expert would refer to his/her trustee’s decision matrix according to the degree of trust acceptance, and modify the decision matrix through information interaction and negotiation; Then, when the number of expert discussions was met, the group decision matrix was calculated. Finally, the interactive TODIM group decision making method under trust network and the TODIM method were applied to calculate the final ranking results of each alternative, and the ranking results were compared. Moreover, the sensitivity analysis was performed about the number of expert discussions and trust acceptance. The case analysis results show that the interactive TODIM group decision making method could fully integrate trust network, ensure the multi-stage information interaction and feedback process in the decision-making process, and is superior to the comparison algorithm in comparison analysis and sensitivity analysis.

摘要: 针对在群体决策中如何利用专家之间的社会关系和决策专家的有限理性因素的问题,提出了一种信任网络下的交互式TODIM群体决策方法。首先,根据专家讨论次数,在每一次专家讨论中,专家根据信任接受程度参考信任者的决策矩阵,通过信息交互和协商来修改决策矩阵;其次,当达到专家讨论次数时,计算最终的群体决策矩阵;最后,分别运用信任网络下交互式TODIM群体决策方法和TODIM群体决策方法来计算各方案排序。对结果进行对比分析,并对专家讨论次数和信任接受程度进行灵敏度分析。案例分析结果表明,交互式TODIM群体决策方法能充分结合信任网络,保证了决策过程中多阶段信息交互和反馈过程,并在对比分析和灵敏度分析上优于对比算法
