An Analysis Method of Black Swan Event based on Impact-spread Tree

Journal of Risk Analysis and Crisis Response (JRACR), 2020
The black swan event has the characteristics of rarity and serious consequences. At present, the analysis of black swan events is generally preconceived (that is, the event is assumed to be a black swan event, and then the influence of the event is ...
