Abstract

Abstract: In view of the existing methods of multi-attribute group decision-making, the influence of social network and decision-makers’ limited rational factors is not considered, TODIM（TOmada de decis?o interativa multicritério） based on trust relationship is proposed for group multi-attribute decision making considering trust relationship in a social network. The trust relationship among experts is established. The leader, the trust relationship matrix and the evaluation matrix are obtained. According to their own confidence levels, experts, adjust the superiority of alternatives according to the evaluation matrix of leaders. The TODIM method is applied to calculate the final ranking results of alternatives, compared with the ranking results obtained without the trust relationship. Moreover, the sensitivity analysis of the degree of confidence is performed. An example is given to illustrate the feasibility and effectiveness of the proposed method.

Key words: TODIM, trust relationship, group decision making, confidence level, leader

摘要： 针对现有多属性群体决策方法较少考虑社会网络和决策者有限理性因素的影响，考虑到社会网络中的信任关系，提出了基于信任关系的TODIM（TOmada de decis?o interativa multicritério）群体多属性决策方法。根据决策专家之间的信任关系，计算出信任网络中的领导者、信任关系矩阵以及评价矩阵等。专家根据自身的自信程度来参考领导者的评价矩阵，调整备选方案的优势度。运用TODIM方法计算各方案最终的排序结果，并与未考虑信任关系时得出的排序结果进行比较，并对自信程度进行灵敏度分析。算例结果说明了该方法的可行性和有效性。结合信任网络和TODIM决策方法的性质和研究现状，对未来的研究发展方向进行了展望。
