Research On Recovery And Gate Resource Allocation After Flight Delays

With the rapid development of China’s civil aviation,the service quality of it has been focused on and belonged to National Thirteenth Five-year Planning Outline.While at the same time,because of the bad weather and other factors,flight delay is more and more prominent and the delay degree is more and more serious.It has seriously affected the promoting of China’s civil aviation service quality and the implementation of China’s air power strategy.Therefore,it is of great practical significance to study the disposal measures of flight delay,to speed up the delay of passenger disposal recovery,to reduce the cost of economic loss,and to improve the quality of transport services.The recovery strategy after flight delay was mainly studied in this paper.First of all,the early warning research of mass incidents after the flight delay was studied,through the selection of appropriate evaluation indicators,the use of fuzzy comprehensive evaluation method,an early warning model was built.Example test showed that it has about 80% warning success rate,can provide effective decision-making assistance.Secondly,the recovery strategy after flight delay was studied,the recovery model was constructed with the objective of minimizing the total economic loss,and Hungarian algorithm was used to solve the model and to determine the flight delay recovery sequence.The example showed that the minimum economic loss method can save about 9.8% of the economic loss than the general first come first service solution,which can provide reference to the airline’s flight delay recovery operations.Finally,the deployment of congestion boarding gates under the premise of resources can be used was studied,it can reduce population density,accelerate recovery speed and reduce delay costs.Using the shortest walking distance of passengers after the deployment as the target condition,type matching principle,the same service company security requirements,the gate service uniqueness conditions as the constraint conditions to establish the allocation model,it is of certain practical value.
