Second, three quantified indexes of urban disaster risk management were taken as the input of DEA appraisal as well as the four values of risk uncertainty as the output to model the performance appraisal of urban disaster risk management. Taking a city as an example, the DEA performance appraisal was implemented for the latest decade.
