Research On Airline Freighter And Belly Adaptability Based On Utility Theory

The world economy recovers at a slow speed and the need of air cargo maintains in recession;the belly transport capacity of wide-body aircraft keeps increasing and the transport capacity is seriously excessive;the load factor of cargo aircraft,daily utilization factor and aircraft cargo price keeps going down,which makes the profitability of whole air cargo industry in a very low standard.Faced with the above market situations,the industry is undergoing a heated debate about freighter and passenger aircraft belly transport.As the production tool,freighter is faced with a trust crisis,and this makes different cargo company take different measures.It believes the root cause of the argument lies in that there is no absolute understanding of the nature and adaptability of freighter and passenger aircraft belly as the main production tool of air cargo transport.In order to fully recognize and understand the transport capacity of freighter and passenger aircraft belly,the paper first segments the air cargo market using the market segmentation theory and summarizes the characters of the market demanding parties,meanwhile,the paper conducts a comparative analysis of the characters of freighter and passenger aircraft belly's cargo transport capacity based on constructing comparative concept model;then based on the segmented air cargo market characters,the paper construct the Binary Logit utilization function model and analyze the adaptability of freighter and passenger aircraft belly with quantitative methods.With the example of air express market,the paper constructs the utilization function and uses the maximum likelihood method to demarcate parameters and uses Matlab to calculate the value.Based on above analysis and combined with systematic comparisons of freighter and passenger aircraft belly,the paper gives appraisals on the usability of freighter and passenger aircraft belly.Lastly,the paper gives relevant strategies and suggestions to domestic cargo airlines based on conclusions.
