Research On Risk Assessment Of Airline Operation Monitoring

The main purpose of risk control of airline flights is to control the risks in the process of flight operation,so as to control the risks to a reasonable extent.In the course of risk control,a comprehensive analysis of the entire system is required to effectively identify the hazards that may exist in each link and to import the relevant information into the established risk database.Related information need to be analyzed and evaluated,so as to identify the corresponding risk control strategies.Firstly,the whole process of the operation monitoring of the airlines in the current stage is expounded.Some of the aviation accidents occurred in recent years have been investigated,and some key data have been recorded,which further points out that with the rapid development of our airlines,the security situation has got some clear inconsistency.Based on the above basis,the risk management must be carried out for airline at current stage.In this paper,the impact indicators of the operation of the airline monitoring were analyzed,and the evaluation index system was also established.The basic principles of BP neural network are used to establish the corresponding safety risk assessment model.The results of the model show that the evaluation index has certain validity,which is of great significance to the improvement of domestic airlines risk management in the current stage.Secondly,this paper also analyzes the characteristics of fuzzy comprehensive evaluation method,analytic hierarchy process,evidence theory and triangular fuzzy analysis,and creatively introduces BP neural network into the model construction process of airline operation monitoring risk evaluation,And the algorithms used in the model are discussed in detail.And some necessary shortcomings of the current BP neural network are put forward.In order to avoid the influence of some experts in the process of research,to improve the objectivity of the study,the entropy method is also used to deal with the relevant indicators.Finally,the paper also analyzes the sensitivity of the established evaluation index system and finds out the most important indicators,and also puts forward some specific suggestions for the key indicators.This is of great importance to the airline.
