Research On Stability Of Flight Recovery Plan

Flight schedules are disturbed into irregular flight by the bad weather,aircraft failure,flow regulation and other external conditions of interference.The irregular flight not only cause passengers travel inconvenience,but also affect the efficiency of air transport and increase the operation cost of airlines.Schedule recovery is the whole world problem,all the airlines need to deal with the problem.On the one hand,we have to ensure the stability of schedule recovery,on the other hand,the speed of schedule recovery is of great significance to the normal operation of airlines.This thesis studies the theories,model and algorithms of flight schedule and schedule recovery.In the first place,the thesis explains the reason and present situation of flight schedule,introduce the strategy and model of schedule recovery,analysis their differences,advantages and disadvantages.Then,the research on the stability of irregular flight recovery is divided into two steps,firstly,in terms of preanalysis measures,according to the historical data of the airline,it can accurately calculate the delay time of the historical flight plan,and make rational analysis and scientific forecast for the future flight plan,lay the foundation for airlines to formulate reasonable flight plan,reduce the probability of abnormal flights to make efforts to alleviate the difficulty of abnormal flights do a good job paving the way to restore the difficulty.Secondly,after remedial measures in the flight recovery study on the basis of the establishment of a heuristic algorithm model,And efficient solution strategy to ensure the speed of flight recovery plan at the same time and to ensure flight stability of the restoration plan.Finally,the program and implementation algorithm are designed on Visual Studio 2015 platform in C ++ language.The correctness and validity of the flight restoration plan are validated by the test and analysis of the examples.
