Abstract: In recent years, multiple inducing information are often derived from frequent outbreaks of emergencies because of their suddenness, harmfulness and uncertainty, which usually arouse the panic of the public and dominant the formation and evolution of public opinion crisis (POC). However, the existing studies are less concerned with the decision-making problem of responding to POC under the situation of multiple inducing information. Therefore, this decision-making problem is first described on the basis of introducing basic theories and methods. Then, after analyzing the attribute structure of inducing information, a quantitative approach is developed at the attribute level based on prospect theory, to calculate the public satisfaction with development trend of multiple inducing information under the specific scenario and response plan of POC. Further, considering the impact of response plans on the evolution of scenarios of POC, a risk decision method is proposed based on cumulative prospect theory from the perspective of the intervention of the public satisfaction, to select optimal plan from alternatives. Finally, taking the decision-making problem of responding to POC in the situation of a major infectious disease epidemic as an example to illustrate the potential application and validity of the proposed method. The results show that the proposed method could obtain optimal plan from alternatives on the basis of simultaneously considering the public satisfaction, behavioral characteristics of decision-makers and the effects of response plans on the evolution of scenarios of POC at the level of attributes of multiple inducing information. The studies could not only enrich the system of decision-making method for selecting optimal plan from alternatives in response to POC under the emergency management paradigm of "scenario-response", but also provide theoretical references for the prevention of potential secondary events derived from POC, such as material panic buying, unlawful assembly and group petitions.
