More specifically, the invention relates to a civil aviation core element configuration optimization method based on mixed integer dynamic programming. Background Civil aviation transportation is used as a core component of a national comprehensive transportation system, and plays an irreplaceable role in promoting economic and social development, improving travel efficiency and the like. However, civil aviation is also an important field of energy consumption and carbon emission, and the carbon emission has the characteristics of wide coverage, complex space-time distribution, high emission reduction difficulty and the like. Along with the promotion of the global 'carbon neutralization' and 'carbon reaching peak' targets, the China civil aviation industry faces severe emission reduction pressure, namely according to the 'fourteen five' civil aviation green development special project, the continuous reduction of the carbon emission intensity is realized while the increase of the transportation requirement is ensured, and finally the carbon neutralization target of the whole industry is reached in 2060. The carbon emission of the civil aviation system is closely related to the configuration of core elements (airports, airlines, fleets, flight operations and the like), for example, the matching efficiency of the machine type and the airlines directly influences the fuel consumption of a single shift, the airport capacity and the network layout of the airlines determine the turnover efficiency of the flights, and the density of the flights frequently is related to the total energy consumption. However, in the configuration optimization of civil aviation core elements, due to the lack of deep fusion of multi-source heterogeneous data (including refined carbon emission and passenger demand fluctuation data), the carbon cost and the traditional operation, passenger time cost and the like are not uniformly quantized into the total cost of the system, multi-period dynamic association and uncertainty robust constraint are lacked, and the coupling of high-dimensional discrete variables and complex constraint is difficult to efficiently process by a solving algorithm, so that the global dynamic optimization of the civil aviation core elements cannot be realized, and the cooperative requirements of improving the operation efficiency and reducing the carbon emission under the view of the carbon cost are difficult to be met. In view of the foregoing, it is desirable to provide a method for dynamically optimizing civil aviation core element configuration based on mixed integer dynamic programming so as to reduce carbon emissions.
