[0017] S2. Acquire, according to the first flight information, a plurality of first positions corresponding to a plurality of to-be-selected parking stands matching the first flight information.

[0018] In this embodiment, the plurality of parking stands to be selected must all meet the following requirements: the aircraft types available for take-off and landing at the plurality of parking stands to be selected include the aircraft type of the first flight, and the plurality of parking stands to be selected are idle within a preset time.

[0019] It should be noted that this matching process ensures the rationality of the aircraft position allocation and avoids problems such as aircraft model mismatch or time conflict. The preset time is set according to the actual operation scenario to meet different aircraft position change scenarios.

[0020] S3. Taking the landing point of the first flight contained in the first flight information as the starting point and the multiple first locations as the end points, based on the landing time of the first flight contained in the first flight information and the estimated airport runway conditions, simulate and calculate multiple first arrival times corresponding to the multiple parking positions to be selected.

[0024] In this embodiment, the target parking position is determined from the parking positions to be selected according to the multiple first arrival times, specifically: the parking position to be selected corresponding to the earliest arrival value among the multiple first arrival times is determined as the target parking position.

[0025] It should be noted that each first path corresponds to one arrival time, and each to-be-selected parking position corresponds to multiple arrival times.

[0026] It should be noted that the runway distribution information includes the use status of the runway at each time, including disabled, occupied, and available. All first paths are paths that can be used for the flight model corresponding to the first flight to transfer, and there will be no conflicts during the transfer process.
