摘要
随着决策面临的环境越来越复杂,个人决策因其局限性难以达到有效决策的标准,致使群体决策变得更为常见;而当决策者行动时,常需考虑他人的判断和行为,使得从众行为成为群体决策中的重要影响因素.因此,文章基于模糊偏好关系提出一种考虑从众行为的群体共识决策方法,能有效节省达成共识所付出的成本.首先,根据模糊偏好关系的特征,设计一致性检验方法和调整模型,为后续的共识达成提供可靠的偏好关系.其次,考虑到专家受到群体规范的压力而产生从众行为,从而对初始效用值进行修正.然后,提出考虑从众行为的最小成本共识模型,进一步设计相应的共识达成算法.最后,计算各已选方案到理想点的距离,运用TOPSIS方法对已选方案进行排序,并通过一个企业产品升级改良的算例来分析说明所提方法是有效的和可行的.
Abstract
With the increasingly complex environment faced by decision-making,in-dividual decision-making is difficult to meet the standards of effective decision-making due to its limitations,making group decision-making more common;when decision-makers take action,they often need to consider the judgments and behaviors of others,making conformity behavior an important influencing factor in group decision-making.Therefore,this paper proposes a new group consensus decision-making method based on fuzzy preference relationships that considers conformity behavior,which can ef-fectively save the cost of reaching consensus.Firstly,in order to provide reliable preference relationships for subsequent consensus building,consistency testing meth-ods and adjustment models are designed according to the characteristics of fuzzy preference relationships.Secondly,considering that when experts are under pressure from group norms,they will exhibit conformity behavior,so we need to modify the initial utility value.Then,a minimum cost consensus model considering conformity behavior is proposed,and corresponding consensus reaching algorithms are further designed.Finally,we calculate the distance from each selected solution to the ideal point,use TOPSIS method to rank the selected solutions,and analyze and demon-strate the effectiveness and feasibility of the proposed method through an example of enterprise product upgrading and improvement.
