摘要：
Aiming at the great influence that extreme preference members playing in emergency decisionmaking, influence model of individual extreme preference is constructed. By combining the direction and distance of risk preference vector, a new risk preference similarity model for decision-making members is put forward. From this model, the extremists group is divided into two groups: Homogeneous group and heterogeneous group. On this basis, the degree of subjective acceptance for non-extreme preference members is introduced in order to explain the acceptance degree that non-extreme preference members to the homogeneous group and heterogeneous group. Risk preference evolution model for multi-stage large group emergency decision-making is further constructed. Finally, the rationality and validity of the model are verified by the contrast analysis of the data simulation results in case study. © 2019, Editorial Board of Journal of Systems Engineering Society of China.
