Methods Research on Airline Nonlinear Coefficient Optimization and Software Implementation
The issues of unclear definition of the nonlinear coefficient for flight routes in civil aviation and the absence of flight prompt software for direct flight routes are addressed.In response,a calculation method for the nonlinear coef-ficient of flight routes is proposed,and a flight prompt software for direct flights is designed and implemented.Firstly,the"city pairs"nonlinear coefficients proposed by the China Civil Aviation Administration are summarized,and their use in the evaluation of flight route networks is discussed.However,it is found that the existing coefficients fail to con-sider the factors of air traffic flow.Consequently,a new calculation method for the nonlinear coefficient is proposed,taking into account air traffic flow.Secondly,the relationship between different nonlinear coefficients and direct flight routes,as well as the strategies adopted by airlines,is analyzed.Furthermore,based on the nonlinear coefficient of flight routes,a flight prompt software for direct flights is developed,and detailed algorithms and implementation methods for the prompt feature are provided.Lastly,illustrative examples and case studies are presented to demonstrate the effec-tiveness of the proposed algorithms and software.
