Research on influence degree of emergent events based on Bayesian network

Knowledge denotation and deduction of uncertainty are important issue to be solved in evaluating influence degree of emergent events. Aim at the diversity, uncertainty and fuzziness of assessment information about emergent event, based on the merit of Bayesian network in dealing with uncertainty influence, the Bayesian network emergent event influence assessment model and corresponding deductive decision-making method were presented in this paper. The results show that the assessment model can improve the assessment accuracy and ability of the response to the influence of emergent event.
