According to the invention, the push-in limited time and the push-out limited time of the machine positions with parking sequence limitation are dynamically calculated according to the machine position parking sequence rule and the real-time change of flight information, so that the situation that an airplane is pushed in the machine positions in the push-in limited time range or pushed out in the machine positions in the push-out limited time range is avoided.

Description
Technical Field
The invention belongs to the field of airport operation optimization, and particularly relates to a method for processing an airport parking sequence.
Background
With the rapid development of civil aviation industry, the taking-off and landing times of a plurality of airports are close to the saturation state, the situation of the shortage of the airplane positions is increasingly prominent, and the airplane positions become a big bottleneck for restricting the operation of the airports. How to more fully utilize the existing airport resources becomes a problem to be solved urgently in airports. Due to the positions of some stands and the models of the parked airplanes, after an airplane is parked in a certain stand, some adjacent stands may be blocked, so that the airplane cannot be pushed into the adjacent stands after landing or the airplane already parked in the adjacent stands cannot be pushed out in time. For such stands with parking sequence restrictions, the current airport practice is to use such stands as little as possible, because such stands can only be manually judged by workers through personal experience, video monitoring and other means to determine whether each limited stand can be pushed in or pushed out. Once a fault occurs, it may have the consequence of scraping the aircraft even more seriously. Therefore, the utilization rate of the airplane seats with parking sequence limitation is generally low, the use problem of the airplane seats is solved, the situation of tension of the airplane seats can be effectively relieved, and the safe operation of an airport is greatly facilitated.
Disclosure of Invention
The invention aims to: the method for processing the parking sequence of the machine positions solves the problem that the machine positions which can obstruct the adjacent machine positions in the prior art are used, dynamically calculates the push-in limited time and the push-out limited time of the machine positions with parking sequence limitation according to the real-time change of flight information, and avoids the situation that the plane is pushed in the machine positions in the push-in limited time range or pushed out in the machine positions in the push-out limited time range.
The important concepts and logics involved in the present invention are as follows:
(1) a host position: some airports in airports may have limited adjacent airports due to factors such as location and model of parked airplanes when parked, so that airplanes cannot be pushed into adjacent airports after landing or airplanes already parked in adjacent airports cannot be pushed out in time.
(2) Pushing into a restricted station: when the airplane is parked on the main station, the airplane cannot be pushed into the station due to the influence of the airplane parked on the main station.
(3) Pushing out the limited machine position: when the airplane is parked on the main station, the parked airplane cannot be pushed out due to the influence of the airplane parked on the main station.
(4) Parking time: the time from the pushing machine position to the pushing machine position is indicated,setting the time of the pushing machine to t1The time of the pusher is t2If the push-in safety threshold is m and the push-out safety threshold is n, the push-in limited time of the push-in limited machine position is (t)1-m，t2+ m) and the push-out limited time of the push-out limited station is (t)1-n，t2+ n); when no airplane is allocated on the main station, the push-in limited time of the push-in limited station and the push-out limited time of the push-out limited station are absent.
Further, the time t of pushing the airplane position of the airplane carrying the flight1And the pusher position time t2The calculation formula of (a) is as follows:
before arrival of the inbound flight, no arrival time is predicted: t is t1The scheduled arrival time of the inbound flights + a threshold;
before the arrival of the inbound flight, there has been an estimated arrival time: t is t1The estimated arrival time of the inbound flights + a threshold b;
after arrival of the inbound flight, there is no turn-up time: t is t1The actual arrival time of the inbound flights + a threshold value c;
after the inbound flight arrives, the gear-in time is up: t is t1The gear-shifting time is set;
before departure of the departure flight, no departure time is predicted: t is t2The scheduled takeoff time of the departure flight is defined as a threshold value d;
before the departure of the departure flight, the estimated departure time is as follows: t is t2The estimated takeoff time of the departure flight is defined as a threshold value e;
after the departure flight takes off, the wheel gear removing time is not as follows: t is t2The actual takeoff time of the departure flight is the threshold value f;
the departure flight has the wheel gear removing time: t is t2And (4) removing the wheel gear.
(5) The parking sequence of the machine positions is regulated as follows: determining a host position and related push-in limited machine positions and push-out limited machine positions; the time of pushing the limited airplane position into the airplane is out of the limited time range of pushing the airplane into the main airplane position, and the time of pushing the limited airplane position out of the limited time range of pushing the airplane out of the main airplane position.
