| With the development of China’s economy,the increase of the number of airports and the increase of the number of operating aircraft,the network structure of airline operation is becoming more and more complex,and the number and types of operating fleet aircraft are also increasing.For Airlines,fleet operations are crucial to corporate earnings,so the degree to which the fleet matches the airline network directly affects corporate earnings,however,the existing research on fleet and route network,such as aircraft type selection and fleet planning,can not directly reflect the matching degree.In order to solve this problem,this paper decided to study the matching degree between the air fleet and the route network.In this paper,based on the summary of relevant ideas,we decide to establish a two-stage matching degree model to calculate the matching degree.In the first stage,a fleet planning model based on capacity optimization is chosen after comparison.The MODEL is set up to obtain the virtual fleet configuration under the combination of the alternative aircraft types.Then the second stage matching degree model is established,and the SBM-DEA model considering the undesired output is selected.Taking as DMU the configuration of each virtual fleet resulting from the first phase the number of types of aircraft in each fleet,the number of operational aircraft and ASK as input indicators and the profit and RPK as expected output indicators,CO2 emissions from the aircraft fleet as a non-expected output indicator.After calculation,the relative efficiency of each virtual machine fleet configuration scheme can be obtained,which can reflect the degree of resource utilization.Finally,by means of numerical simulation,a network of 50 point-to-point routes is set up,and six alternative aircraft types are selected,and a matching degree model is established and analyzed,carry out sensitivity analysis of demand,frequency and unit resources,find out their respective trends and analyze and explain them. |
