IMPROVED AHP-GROUP DECISION MAKING FOR INVESTMENT STRATEGY SELECTION
提出一种改进的层次分析法群体决策模型，通过最小二乘法调整判断矩阵并邀请五位专家评估，降低投资风险，实证表明该模型准确有效且符合实际投资环境。
Investment strategy selection relies heavily on personal experience and behavior. This paper proposes an improved Analytical Hierarchy Process-group decision making (IAHP-GDM) model to reduce investment risk. This model applies the method of least squares to adjust group decision matrix in order to satisfy the property of positive reciprocal matrix in AHP. In addition, five experts from related fields are invited to evaluate investment risk that takes group wisdom to eliminate personal bias. An empirical study is conducted to compare the proposed model to AHP for group decision making model. The results show that the IAHP-GDM model is not only accurate and effective, but also consistent with realistic investment environment.
