The Safety Evaluation Method Research Of Airport Service Process Under Abnormal Flight

With the improvement of aircraft manufacturing level and the increscent proportion of aviation transportation,civil aviation market share gradually expanding.As the transit nodes of civil aviation transport,airport terminal plays an important role and function that focus on the hot issues in due to abnormal flight caused by flight delays and safety concerns.The majority researchers focused on the flight back problems and passenger compensation mechanism research for the study of abnormal flight problems at home and abroad,lack of its root cause analysis of safety issues,terminal service process optimization and related research.In this paper,the queuing network model is established about terminal passenger service in the quantitative analysis of the service process from the perspective of steady and unsteady bottlenecks.Firstly,the root cause and safety risk characteristics analysis is carried out abnormal flight,the correlation between abnormal flight reason and flight rank is analyzed using the rough set method,the judgment criterion of early warning level is established for abnormal flight;secondly,the queuing network model is established for terminal passenger service process to account the index of average queue length and average stay time,analysis of the bottleneck of service process from the prospect of steady and unsteady queuing system;thirdly,the feasibility of queuing network model in the service process bottlenecks is assessed choosing a domestic terminal departure process;finally,the optimization model is established for passenger service process,calculating the minimum quantity of service facilities and its efficiency for system safe and smooth operation,validating with a domestic terminal examples.With the relationship analysis between the root causes and safety early warning for abnormal flight,it assists managers to improve process or reconstruct,upgrade services,eliminate the restriction of the bottleneck link to a certain extent,improve the service level of airport,reduce the risk of all kinds of trigger event.
