A fuzzy risk attitude classification based on prospect theory

Traditional methods do not actually measure peoples' risk attitude naturally and precisely. Therefore, a fuzzy risk attitude classification method is developed. Since the prospect theory is usually considered as an effective model of decision making, the personalized parameters in prospect theory are firstly fuzzified to distinguish people with different risk atti-tudes, and then a fuzzy classification database schema is applied to calculate the exact value of risk value attitude and risk behavior attitude. Finally, by applying a two-hierarchical classification model, the precise value of synthetical risk attitude can be acquired.
