| In recent years,the capacity of Urumqi airport has become saturated.In order to improve the capacity and achieve safe operation,Urumqi airport plans to add two runways by 2025.In order to have an objective and clear understanding of the overall operation before and after the expansion of Urumqi airport,and provide decision-making basis for the expansion of the airport,it is particularly important to study the simulation of Urumqi airport operation.The operation of Urumqi Airport before and after expansion is studied from various angles。Firstly,the general situation of Urumqi airport and queuing network model are introduced,and the distribution rule of interval time of flights is discriminated by x~2-fitting test method.Secondly,the queuing network model and AIRTOP simulation model of Urumqi Airport are established.Clustering algorithm is used to analyze the distribution curve of arrival and departure flights in Urumqi Airport from January to September 2017,and the clustering results are evaluated by the evaluation index of"CP index".Thirdly,the queuing network model is solved,and the results of queuing network model and AIRTOP simulation model are compared with the actual operation,which verifies the reliability of the queuing network model and AIRTOP simulation model.Finally,the queuing network model and AIRTOP simulation model of Urumqi Airport are established.Through the comparative analysis,the operation capacity and delay of the expanded Urumqi Airport are obtained.In a word,queuing network model is innovatively applied to airport operation simulation,and achieved good results.On the one hand,decision-making basis for decision-makers of airport expansion is provided,avoiding the problem of"build first,repair later"in a certain extent,on the other hand,new ideas for the analysis of arrival and departure flights delay and airport operation simulation are also provided. |
