Abstract

Aiming at the problems of randomness and fuzziness in the railway emergency，and multiple scenarios in the evolution of the railway emergency, a multi-attribute group decision-making method of railway emergency is proposed based on prospect theory. Firstly, the uncertainty transformation of linguistic decision-making information is realized using the qualitative and quantitative transformation characteristics of cloud model. Secondly, the cloud distance and the cloud possibility degree are defined according to the concept of interval number, then the cloud prospect decision matrices of each decision-maker are constructed. The attribute weights of each decision-maker are obtained through establishing the attribute weight optimization models based on the principle of maximum prospect value of every alternative. Thirdly, the decision-maker weights are determined based on group’s consistency and the maximum entropy, and the best alternative is obtained by comparing the whole prospect value of alternatives. Finally, the validity and feasibility of the method are verified by an example.
