Because of the complex and massive risk factors of a large-scale activity, it is difficult to assess the risk level for such activities with an accurate numerical value. Therefore, a fuzzy linguistic based approach was proposed to evaluate the risk level of large-scale activities. Taking Jay Chou’s concert in 2016 as a case study, a hierarchy structure for risk assessment index system was built from the interviews with experts and literatures, which contain 14 risk factors in 4 groups. A five-point scale linguistic term was designed for the experts to evaluate the risk level of risk factors, and a fuzzy synthetic assessment model was adopted to present the procedures of risk assessment. The results reveal that the top risk factor is “safety education” and the top risk group is “management”, and the overall risk criticality (RC) is considered as middle. Based on the rank of RC both for risk factors and risk groups, some risk management strategies were suggested.
