摘　　要：本文在行为投资组合模型的基础上,引入模糊数学来描述投资者在多心理账户下投资决策过程中的多种模糊属性,用隶属度函数刻画投资者的心理满意度。本文在投资收益服从Log-Normal分布,用下偏矩的方法度量每个心理账户的风险承受度。最后根据模型给出了相应的数值模拟。With the mental accounts as the theoretical framework and on the basis of behavior portfolio model, this paper introduces fuzzy mathematics to describe multiple fuzzy attributes of investors in decision-making process. The investor＇s mental satisfaction is depicted by using membership functions. In this paper, the investor＇s profits are subject to Log-Normal distribution. The risk tolerance of every mental account is measured by means of lower partial moment. Finally, the corresponding numerical simulation is suggested based on the model.
