[0027] The method of the invention will be further described below in conjunction with the accompanying drawings.
[0028] First define some variables in the flight schedule.
[0029] Variables related to aircraft type i include seat capacity S i , Hourly flight cost C i , The daily utilization rate U i And the number of aircraft A i . Variables related to the flight route include, fare V ij And load factor R ij , Where j represents the route of the aircraft. In addition, use T ij Represents the flight time (range) of aircraft i on route j. The variables of these problems are shown in the following table:
[0030]
[0031] The optimization goal of the aircraft flight planning problem is to optimize the flight frequency of each aircraft on each route under the premise of satisfying a series of constraints, so as to maximize the profit. We use x ij Indicates that model i has x on the route of j every day ij Times round trip, then the solution of the problem can be expressed as fol...
