Aviation risk evaluation method and device and computer equipment

The invention discloses an aviation risk evaluation method and device and computer equipment. The method comprises the steps of obtaining monitoring project data of a to-be-evaluated object, wherein the monitoring project data is monitoring data used for representing an unsafe event in an aviation process; calculating a comprehensive risk quantitative index of each flight of the to-be-evaluated object in the evaluation period according to the monitoring project data; calculating a probability density function of the risk quantitative index of the to-be-evaluated object in the evaluation periodaccording to the comprehensive risk quantitative index of each flight; calculating a doubled deviation relative risk value, a doubled deviation relative risk value and a tripled relative deviation risk value according to the probability density function of the risk quantification index of the to-be-evaluated object and a preset probability density function of the risk quantification index of thewhole historical flight; a
