摘　　要：【目的/意义】针对投资决策中偏好信息为区间模糊数的多准则决策问题,提出了一种基于冲突最小化的群体决策方法。【设计/方法】首先,以决策整体最优为目标,构建极大熵规划模型求解决策准则权重;其次,以决策总冲突程度最小化为目标,构建优化模型求解决策成员权重;然后,建立决策方案的比较可能度矩阵和排序向量模型,获得问题决策方案排序结果。最后,通过一个投资决策实例进行应用,验证了方法的有效性和科学性。【结论/发现】该方法能够解决投资群体决策中的冲突问题,在投资决策中形成偏好最一致的决策方案。[Purpose/Significance]Due to the multi-criteria decision-making issue in which the preference information acts as interval fuzzy number,a group decision-making method based on the minimized conflict is proposed.[Design/Methodology]Firstly,the maximum entropy model is constructed to solve the decision criteria weights with the overall optimal decision as the objective.Secondly,the optimization model is constructed to solve the decision-makers’weights with the objective of minimizing the total decisional conflict degree.Then,the comparison possibility matrix and ranking vector model of decision alternatives are established to obtain the ranking result of decision alternatives.Finally,an investment decision-making example is given to verify the effectiveness and scientificity of the method.[Findings/Conclusions]The method can solve the conflicts in group investment decision-making and form the most consistent preference decision alternatives when making investment decisions.
