英文摘要：

In view of the multi-criteria decision-making problem that probabilities and the criteria values of alternatives are both three-parameter interval grey number, a risky decision-making approach based on prospect theory is proposed. In this method, firstly, the distance and the exact function of three-parameter interval grey number are defined, and on the basis of the analysis and discussion of its properties, a three-parameter interval grey number comparison method is defined. Secondly, we give the definition of the prospect value function and the probabilities weighting function of three- parameter interval grey number. Then, the prospect value of each alternative is calculated based on multi-reference point, and the integrated prospect decision matrix is constructed by giving the reference point aggregating operator. Moreover, the integrated prospect value of each alternative is aggregated by the integrated prospect decision matrix and the optimal criteria weights given by the optimization model. After that we can order these alternatives by comparing their integrated prospect values. Finally, an example is presented to examine the effectiveness of our method.
