Aviation risk evaluation method and device and computer equipment

Abstract

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; and calculating a relative risk evaluation index of the to-be-evaluated object in the evaluation period according to the one-time deviation relative risk value, the two-time deviation relative risk value and the three-time relative deviation risk value, and evaluating the risk of the to-be-evaluated object.

Description

technical field [0001] The invention relates to the technical field of aviation risk, in particular to an aviation risk assessment method, device and computer equipment. Background technique [0002] The quantification and evaluation of civil aviation risks play a very important role in aviation safety and aviation management. At present, the mainstream method adopted by aviation management departments and airlines is to conduct risk assessment based on the number of overrun events of each monitoring item, and mainly focus on the evaluation of a single flight. This approach cannot be used for multi-dimensional aviation risk assessment. However, for the aviation management department, there are many dimensions to the assessment and comparison of aviation risks, such as: comparison between airlines, comparison between routes, comparison between airports, comparison between different aircraft type comparisons, etc. Contents of the invention [0003] In view of this, in ord...
