Description

[Technical Field]

[0001] The present invention relates to an operation control system for managing the operation of a plurality of ground support devices deployed at an airport. [Background technology]

[0002] Traditionally, airports have been equipped with multiple pieces of ground support equipment (GSE) to perform various tasks. This ground support equipment is called GSE, and there are various types of GSE, such as high-lift loaders, belt loaders, towing tractors, and passenger steps. Currently, when performing work using GSE, workers check the flight schedule and arrange for the necessary GSE before starting the work. Summary of the Invention [Problem to be solved by the invention]

[0003] However, it is extremely time-consuming for workers to check flight schedules and arrange for GSEs. Furthermore, the preparations required to carry out the work are complicated, and workers are required to have a great deal of experience and knowledge, placing a heavy burden on them. Furthermore, if workers make mistakes, such as overlooking information, it can affect flight schedules.

[0004] The present invention has been made in consideration of the above-mentioned problems, and aims to reduce the burden on operators in managing the operation of ground support equipment at airports. [Means for solving the problem]

[0005] The present invention is an operation management system that manages the operation of multiple ground support devices deployed at an airport, and is characterized in that it includes a schedule creation unit that creates a work schedule for the multiple ground support devices based on the flight schedule of the airport, and the schedule creation unit transmits at least some of the data related to the work schedule to the ground support devices.

[0006] According to the present invention, the schedule creation unit creates a work schedule based on the flight schedule available in advance from air traffic control. This eliminates the need for workers to check the flight schedule themselves and create a work schedule, thereby reducing the burden on workers.

[0007] In the present invention, it is preferable that the schedule creation unit transmits at least a portion of data relating to the work schedule to a worker terminal carried by a worker who works using the ground support equipment.

[0008] With this configuration, the worker can immediately check the work schedule that concerns him or her by referring to the data received at the worker terminal, thereby further reducing the burden on the worker.

[0009] In the present invention, it is preferable that the worker terminal is capable of transmitting work progress data regarding the progress of work by the ground support equipment to the schedule creation unit, and that the schedule creation unit is capable of re-creating the work schedule taking into account the work progress data.

[0010] With this configuration, the work schedule can be adjusted as needed depending on the progress of the work, so that even if the work is behind schedule, the work can be carried out smoothly.

[0011] In the present invention, it is preferable that the schedule creation unit determines whether or not the work schedule needs to be revised at predetermined time intervals based on the work progress data, and recreates the work schedule when it determines that revision is necessary.

[0012] If the work schedule is revised too frequently in response to the progress of work, workers will have to adapt to the new work schedule each time, which could actually increase the burden on them. Therefore, as described above, by determining whether the work schedule needs to be revised at predetermined intervals and recreating the work schedule only when it is determined that revision is necessary, balanced operation management becomes possible.

[0013] In the present invention, it is preferable that the schedule creation section recreates the work schedule when the work progress data includes data indicating an abnormality.

[0014] With this configuration, if an abnormality occurs, such as a worker becoming ill or a ground support equipment malfunction or accident, the work schedule can be quickly revised, minimizing subsequent work delays.

[0015] In the present invention, it is preferable that, when there is a change in the flight schedule, the schedule creation unit recreates the work schedule based on the changed flight schedule.

[0016] If the originally created work schedule is used as is when there is a change in the flight schedule, confusion may occur at the work site. Therefore, as described above, if the schedule creation unit recreates the work schedule based on the changed flight schedule, workers can smoothly respond to the change in the flight schedule.

[0017] In the present invention, it is preferable that the ground support equipment is capable of transmitting vehicle status data relating to the status of the ground support equipment to the schedule creation unit, and that the schedule creation unit is capable of recreating the work schedule taking into account the vehicle status data.

[0018] According to this configuration, the work schedule can be appropriately adjusted depending on the state of the ground support equipment (for example, the location, the operating status, etc.), thereby enabling smooth operation management of the ground support equipment.

[0019] In the present invention, it is preferable that the schedule creation unit determines whether or not the work schedule needs to be modified at predetermined time intervals based on the vehicle condition data, and recreates the work schedule when it determines that modification is necessary.

[0020] If the work schedule is revised too frequently in response to the status of the ground support equipment, workers will have to respond to the new work schedule each time, which could actually increase the burden on the workers. Therefore, as described above, by determining whether the work schedule needs to be revised at predetermined intervals and recreating the work schedule only when it is determined that a revision is necessary, balanced operation management becomes possible.

[0021] In the present invention, it is preferable that the schedule creation unit recreates the work schedule when the vehicle state data includes data indicating an abnormality.

[0022] With this configuration, for example, if an abnormality such as a breakdown or accident of ground support equipment occurs, the work schedule can be quickly revised, thereby minimizing subsequent work delays. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0024] Hereinafter, an embodiment of an operation control system according to the present invention will be described with reference to the drawings.

[0025] FIG. 1 is a plan view showing airport facilities in a simplified manner. As shown in FIG. 1, airport 1 is provided with a terminal building 2 and a runway 3. Terminal building 2 is provided with multiple gates 4, and boarding bridges 5 are connected to gates 4. Boarding bridges 5 are facilities for allowing passengers and crew to board and disembark from gate 4 to aircraft 100. If boarding bridges 5 are not available, passenger steps, which will be described later, may be used. While aircraft 100 is parked at airport 1, in addition to passenger and crew boarding and disembarking, various operations (ground support operations) are performed, such as loading and unloading of cargo and baggage, refueling, and cleaning of the interior of the aircraft. Then, once ground support operations are completed and preparations are complete, aircraft 100 takes off from runway 3.

[0026] Multiple GSEs 13 are used in ground support operations. GSE stands for Ground Support Equipment. There are various types of GSEs 13, but examples include work vehicles such as a high-lift loader 13a that loads cargo (containers) onto and off the aircraft, a belt loader 13b that loads passenger baggage onto and off the aircraft, a towing tractor 13c that tows the aircraft 100, and a passenger step 13d that allows passengers and crew to board and disembark directly onto and off the aircraft. The airport 1 is provided with a parking lot 6 for parking the GSEs 13 and a maintenance area 7 for performing maintenance on the GSEs 13.

[0027] Currently, arrangements for GSEs 13 are made by workers who operate the GSEs 13. In other words, the workers check the flight schedule, arrange for the necessary GSEs 13, and then begin work. However, it is extremely time-consuming for workers to check the flight schedule and arrange for the GSEs 13. In addition, the preparations before work are complicated, and the workers are required to have a great deal of experience and knowledge, which places a heavy burden on the workers. Furthermore, if a worker makes a mistake, such as overlooking information, it will affect the flight schedule. Therefore, in order to solve these problems, the inventors of the present application have devised an operation management system for GSEs 13 at airport 1. This operation management system will be described in detail below.

[0028] (GSE traffic control system) A traffic management system 10 of this embodiment is shown in Figure 2. The traffic management system 10 includes an air traffic control unit 9, a GSE control unit 11 (corresponding to the schedule creation unit of the present invention), multiple worker terminals 12 carried by each worker, and multiple GSEs 13. The GSE control unit 11 is capable of communicating with the air traffic control unit 9, the multiple worker terminals 12, and the multiple GSEs 13. The main function of the GSE control unit 11 is to create a work schedule for the multiple GSEs 13 based on the flight schedule provided by the air traffic control unit 9, and to simultaneously transmit at least some data related to the work schedule to the multiple worker terminals 12 and the multiple GSEs 13.

[0029] The worker terminal 12 is configured by, for example, a mobile terminal such as a tablet, smartphone, or mobile phone, or a wearable terminal such as smart glasses or a smart watch, and is capable of transmitting and receiving data to and from the GSE control 11. Data related to the work schedule and the like is transmitted from the GSE control 11 to the worker terminal 12. On the other hand, work progress data related to the progress of work and the like can be transmitted from the worker terminal 12 to the GSE control 11. Specific examples of work progress data include data indicating that a specific task has been completed or is delayed, and data indicating an abnormality (such as a worker's poor health or a malfunction or accident of the GSE 13).

[0030] The GSE 13 includes a communication unit 14, a location information receiving unit 15, and an ID reading unit 16. The GSE 13 is capable of communicating with the GSE control unit 11 via the communication unit 14 and is configured to be able to send and receive data to and from the GSE control unit 11. The location information receiving unit 15 can receive, for example, a GPS (Global Positioning System) signal to recognize the location of the vehicle. Note that a positioning method other than GPS may be used to recognize the location of the vehicle. The ID reading unit 16 can read the worker ID held by the worker, determine whether the worker ID matches the scheduled worker, and notify the worker of the result. The worker ID is an ID assigned to each worker. The ID reading unit 16 is configured to be able to read, for example, the worker ID displayed on the worker terminal 12 or the worker ID attached to an ID card held by the worker. Note that the worker ID may be a barcode or an IC tag, or may be manually entered by the worker.

[0031] Data related to the work schedule and the like is transmitted from the GSE control 11 to the GSE 13. On the other hand, the GSE 13 can transmit vehicle status data related to the status of the GSE 13 and the like to the GSE control 11. Specific examples of vehicle status data include location data acquired by the location information receiving unit 15, data indicating the operating status (driving, working, etc.), and data indicating an abnormality (such as a breakdown or accident of the GSE 13).

[0032] (GSE operation management flow) FIG. 3 is a flowchart showing the flow of operation management of the GSE 13 by the operation management system 10. The GSE control 11 receives the flight schedule in advance (for example, the day before) from the air traffic control 9 (step S11). FIG. 4(a) is a table showing an example of data included in the flight schedule, and FIG. 4(b) is a table showing an example of a list of cargo. Note that the cargo in FIG. 4 refers to cargo housed in a container, and is different from passenger baggage. The types of data included in the flight schedule transmitted from the air traffic control 9 to the GSE control 11 are not limited to those shown in FIG. 4 and can be changed as appropriate.

[0033] Upon receiving the flight schedule, the GSE control 11 creates a work schedule based on the flight schedule (step S12). When creating the work schedule, the GSE control 11 also references the worker-related data shown in FIG. 5(a) and the GSE-related data shown in FIG. 5(b) in addition to the flight schedule. The "operation status" and "waiting location" in FIG. 5(b) can be identified by the vehicle status data transmitted from the GSE 13. Note that when creating the work schedule, the GSE control 11 may also reference data other than the flight schedule, worker-related data, and GSE-related data.

[0034] The GSE control 11 identifies the work required for each flight based on the flight schedule, worker-related data, and GSE-related data, determines the worker in charge of each work and the GSE 13 to be used, and creates a work schedule. Figure 6 is a table showing an example of data included in the work schedule. For example, for flight number 1, the table shows that a worker with worker ID 001 will be in charge of cargo removal using a high-lift loader with GSE ID HL-01. In Figure 6, PS indicates a passenger step, TT indicates a towing tractor, and BL indicates a belt loader. The types of data included in the work schedule created by the GSE control 11 are not limited to those shown in Figure 6 and can be changed as appropriate.

[0035] When the GSE control 11 creates a work schedule (step S12), it transmits at least a portion of the data included in the work schedule to the worker terminal 12 and the GSE 13 (step S13). FIG. 7 is a table showing an example of data transmitted to the worker terminal 12, specifically showing the data transmitted to the worker terminal 12 of the worker whose worker ID is 001. When the worker receives the work schedule data on the worker terminal 12 (step S21), the worker can understand the work for which he or she is responsible and the GSE 13 to be used. Therefore, the worker can proceed with the work according to the work schedule without having to check the flight schedule or arrange for the GSE 13 himself or herself.

[0036] FIG. 8 is a table showing an example of data transmitted to the GSE 13, specifically, data transmitted to the GSE 13 with a GSE ID of HL-01. When the GSE 13 receives the work schedule data (step S31), it becomes possible to know which worker will be driving the vehicle and when. Therefore, when a worker uses the GSE 13, the ID of the worker is read by the ID reading unit 16, so that it can be determined whether the worker is the correct worker who matches the work schedule. If the work schedule does not match, this fact is notified to the worker, thereby preventing the worker from using the wrong GSE 13.

[0037] When the worker receives the work schedule data from the GSE control 11 (step S21), the worker performs work according to the work schedule. First, the worker travels to the GSE 13 determined in the work schedule. The location of the GSE 13 can be identified based on the location data acquired by the location information receiving unit 15. When the GSE control 11 creates a work schedule, the travel distance of the GSE 13 may be optimized by using the location data of the GSE 13, for example, by using the GSE 13 closest to the gate 4 where the work will be performed. Upon arriving at the GSE 13, the worker has the ID reading unit 16 read the worker ID. If there are no problems, the worker drives the GSE 13 and performs the specified work.

[0038] At an appropriate timing during or after the work is completed, the worker transmits work progress data to the GSE control 11 (step S22), and the GSE 13 transmits vehicle status data to the GSE control 11 (step S32). When the GSE control 11 receives the work progress data and vehicle status data (step S14), it checks the work progress status and whether any abnormalities have occurred based on the received work progress data and vehicle status data. Then, if necessary, it re-creates the work schedule (hereinafter referred to as rescheduling) (step S15). The circumstances under which rescheduling is performed will be explained in detail later. If rescheduling is performed, at least a portion of the data included in the re-created work schedule is transmitted to the worker terminal 12 and the GSE 13 (step S16).

[0039] Thereafter, the above-described process is repeated. That is, when the worker receives the re-created work schedule data (step S23), he / she works according to the work schedule and transmits work progress data to the GSE control 11 at an appropriate timing (step S24). When the GSE 13 receives the re-created work schedule data (step S33), it is able to determine whether the worker is the correct worker using the worker ID. The GSE 13 transmits vehicle status data to the GSE control 11 at an appropriate timing (step S34). When the GSE control 11 receives the work progress data and vehicle status data (step S17), it executes rescheduling as necessary (step S18).

[0040] (Determine whether to reschedule) The process of determining whether or not to reschedule in steps S15 and S18 will be described with reference to the flowchart in Fig. 9. When a predetermined time (here, n minutes) has elapsed (YES in step S41), the GSE control 11 determines whether or not rescheduling is necessary (step S42). Whether or not rescheduling is necessary is determined based on the work progress data transmitted from the worker terminal 12 and the vehicle status data transmitted from the GSE 13. For example, if the delay time of the work is equal to or greater than a predetermined threshold, it is determined that rescheduling is necessary (YES in step S42), and rescheduling is performed (step S46).

[0041] Even if n minutes have not passed in step S41, if there is a change in the flight schedule (YES in step S43), if an abnormality occurs in the GSE 13 (YES in step S44), or if an abnormality occurs in a worker (YES in step S45), rescheduling is immediately performed (step S46) without determining whether rescheduling is necessary. This will be explained in detail below.

[0042] If the answer is NO in step S41, the GSE control 11 checks whether there has been a change in the flight schedule (step S43). Specifically, it checks whether there has been a change in the flight (change in landing time, change in takeoff time, cancellation), change in gate number, change in runway, change in aircraft type, etc. If there has been a change in the flight schedule (YES in step S43), rescheduling is immediately performed based on the changed flight schedule (step S46). Note that if there has been a change in the flight schedule, the information is sent from the air traffic control 9 to the GSE control 11.

[0043] If the answer is NO in step S43, the GSE control 11 checks whether an abnormality has occurred in the GSE 13 (step S44). Specifically, it checks whether the work progress data transmitted from the worker terminal 12 or the vehicle status data transmitted from the GSE 13 includes data indicating an abnormality in the GSE 13. If an abnormality has occurred in the GSE 13 (YES in step S44), rescheduling is immediately performed so that work can be carried out using an alternative GSE 13 (step S46). If the abnormality in the GSE 13 affects the subsequent flight schedule, such as a collision with the aircraft 100, the GSE control 11 also reports the details of the abnormality to the air traffic control 9. Furthermore, if the occurrence of an abnormality in the GSE 13 requires the dispatch of workers, a tow truck, or an ambulance to respond to the abnormality, it is preferable that the GSE control 11 also make arrangements for these at the same time.

[0044] If the answer is NO in step S44, the GSE control 11 checks whether an abnormality has occurred with the worker (step S45). Specifically, it checks whether data indicating an abnormality with the worker is included in the work progress data transmitted from the worker terminal 12. If an abnormality has occurred with the worker, such as poor health or an accident (YES in step S45), rescheduling is immediately performed to fill in the available worker (step S46). Note that if the occurrence of an abnormality with a worker requires the provision of additional workers or an ambulance to deal with the situation, it is preferable that the GSE control 11 also make these arrangements at the same time.

[0045] When the GSE control 11 executes rescheduling, it transmits data on the new work schedule to the worker terminals 12 and the GSE 13 (step S16 in FIG. 3). At this time, the GSE control 11 may transmit the work schedule data to all worker terminals 12 and GSE 13 at once, or may transmit the data only to the worker terminals 12 and GSE 13 of the workers whose work content will be changed.

[0046] In this embodiment, after determining whether n minutes have passed in step S41, if n minutes have not passed, the GSE control 11 checks for an abnormality in the flight schedule, the GSE 13, or the operator. However, for example, when a change in the flight schedule occurs, the air traffic control 9 may notify the GSE control 11 of the change, and the GSE control 11 may reschedule upon receiving the notification. Similarly, the GSE control 11 may reschedule upon receiving a notification from the GSE 13 or the operator terminal 12 that an abnormality has occurred.

[0047] (effect) As described above, in the traffic management system 10 according to this embodiment, the GSE control 11 creates a work schedule based on the flight schedule available in advance from the air traffic control 9. This eliminates the need for workers to check the flight schedule themselves and create a work schedule, thereby reducing the burden on the workers.

[0048] Furthermore, in this embodiment, the GSE control 11 transmits at least a portion of data related to the work schedule to the worker terminal 12 carried by the worker who performs work using the GSE 13. With this configuration, the worker can immediately check the work schedule that concerns him or her by referring to the data received at the worker terminal 12, further reducing the burden on the worker.

[0049] Furthermore, in this embodiment, the worker terminal 12 can transmit work progress data relating to the progress of work by the GSE 13 to the GSE control 11, and the GSE control 11 can reschedule taking the work progress data into consideration. With this configuration, the work schedule can be appropriately revised according to the progress of the work, so that even if work is delayed, subsequent work can be carried out smoothly.

[0050] Furthermore, in this embodiment, the GSE control 11 determines whether the work schedule needs to be revised at predetermined intervals based on the work progress data, and reschedules the work if it determines that a revision is necessary. If the work schedule is revised too frequently based on the work progress status, workers will need to adapt to the new work schedule each time, which could actually increase the burden on the workers. Therefore, as described above, by determining whether the work schedule needs to be revised at predetermined intervals and rescheduling only if it determines that a revision is necessary, balanced operation management is possible.

[0051] In this embodiment, the GSE control 11 reschedules the work if the work progress data contains data indicating an abnormality. With this configuration, if an abnormality occurs, such as a worker becoming ill or a breakdown or accident of the GSE 13, the work schedule can be quickly revised to minimize subsequent work delays.

[0052] Furthermore, in this embodiment, when a change occurs in the flight schedule, the GSE control 11 performs rescheduling based on the changed flight schedule. If the originally created work schedule is used as is when a change occurs in the flight schedule, confusion may occur at the work site. Therefore, as described above, if the GSE control 11 performs rescheduling based on the changed flight schedule, workers can smoothly respond to the change in the flight schedule.

[0053] In addition, in this embodiment, the GSE 13 can transmit vehicle status data relating to the status of the GSE 13 to the GSE control 11, and the GSE control 11 can reschedule taking the vehicle status data into consideration. With this configuration, the work schedule can be appropriately revised depending on the status of the GSE 13 (for example, its location, operating status, etc.), thereby enabling smooth operation management of the GSE 13.

[0054] Furthermore, in this embodiment, the GSE control 11 determines whether the work schedule needs to be revised at predetermined intervals based on the vehicle status data, and reschedules the work if it determines that a revision is necessary. If the work schedule is revised too frequently based on the status of the GSE 13, the worker will need to respond to the new work schedule each time, which may actually increase the burden on the worker. Therefore, as described above, by determining whether the work schedule needs to be revised at predetermined intervals and rescheduling only if a revision is determined to be necessary, balanced operation management is possible.

[0055] In this embodiment, the GSE control 11 reschedules the work if the vehicle status data contains data indicating an abnormality. With this configuration, if an abnormality such as a breakdown or accident occurs in the GSE 13, the work schedule can be quickly revised, thereby minimizing subsequent work delays.

[0056] (Other embodiments) A description will be given of modifications of the above embodiment, in which various changes have been made.

[0057] In the above embodiment, the GSE 13 is provided with the communication unit 14, and the GSE 13 is configured to be able to communicate with the GSE control 11. However, it is not essential that the GSE 13 be able to communicate with the GSE control 11; it is sufficient that at least the worker terminal 12 be able to communicate with the GSE control 11. It is also possible to omit the location information receiving unit 15 and the ID reading unit 16 provided in the GSE 13. Furthermore, it is also possible to provide the functions of the worker terminal 12 in the GSE 13. In this case, the worker exchanges data such as work progress with the GSE control 11 using an input / output device or the like provided in the GSE 13.

[0058] In the above embodiment, the GSE 13 is operated by a worker. However, the GSE 13 may be configured to be capable of automatic operation. In this case, when a work schedule is transmitted from the GSE control 11 to the GSE 13, the GSE 13 may automatically move to a predetermined location at a predetermined time. This eliminates the need for a worker to travel to the GSE 13.

[0059] In the above embodiment, the GSE control 11 is capable of communicating with the air traffic control 9, the worker terminal 12, and the GSE 13. However, the GSE control 11 may also be configured to be capable of communicating with facilities at the airport 1. For example, the GSE control 11 may be configured to receive passenger-related data from terminals at check-in gates and boarding gates, and to take this data into consideration when creating a work schedule or determining whether to reschedule. Alternatively, the GSE control 11 may be configured to receive data on passenger abnormalities (e.g., sudden illness) from mobile terminals carried by cabin attendants. Furthermore, for terminals connectable to the GSE control 11 and the GSE 13, it is also possible to manage software versions, etc., via the GSE control 11.

[0060] In the above embodiment, at least a portion of the GSE 13 may be electrically powered. In this case, the vehicle status data transmitted from the GSE 13 to the GSE control 11 may include data indicating whether the GSE 13 is being charged or data regarding the remaining power level of the GSE 13. Furthermore, by taking the timing of charging the GSE 13 into consideration when creating a work schedule for the GSE control 11, the GSE 13 can be operated efficiently.

[0061] In the above embodiment, the GSE control 11 may store vehicle operation data including vehicle status data, remaining battery level, location information, etc. of the GSE 13, and may use this data to predict maintenance times, detect faults, and predict faults for the GSE 13. Deep learning or machine learning may be used for predictive maintenance and fault detection. Furthermore, by recording the location information of the GSE 13 at regular intervals and analyzing the route the GSE 13 takes within the airport, it is possible to optimize the algorithm for creating work schedules in the GSE control 11.

[0062] In the above embodiment, the GSE control 11 may utilize the accessory and worker-related data included in the GSE-related data. For example, a power suit may be provided to suit the needs of the worker, or a GSE 13 equipped with an accessory that assists in carrying luggage may be provided.

[0063] In the above embodiment, the GSE control system 11 may be connected to an airport boarding bridge, passenger steps, a shuttle bus that picks up and drops off passengers within the airport, a passenger reservation and ticketing system, etc. For example, a ticket reader may be installed on the boarding bridge or passenger steps, and the GSE control system 11 may be configured to obtain a list of passengers boarding the aircraft from the reservation and ticketing system, air traffic control 9, etc. When passengers board the aircraft via the boarding bridge or passenger steps, the ticket reader reads their tickets and compares them with the passenger list obtained by the GSE control system 11, thereby preventing passengers from boarding the wrong bus. Furthermore, a ticket reader may also be installed on the shuttle bus, and by reading the passenger's ticket when boarding the shuttle bus and comparing it with the passenger list, passengers may be prevented from going to the wrong boarding location. Furthermore, the information read by the ticket reader may not be the ticket itself, but may instead be a barcode, IC tag, or other ID that can identify the ticket or passenger. Furthermore, if the data acquired by GSE control 11 from the passenger reservation and ticketing system or the like includes passengers in wheelchairs, GSE control 11 may deploy a passenger step with a lifter such as that in Patent No. 5105054 or a wheelchair-specific GSE 13. Furthermore, if the arriving aircraft is a government aircraft or if the passengers include state guests, a dedicated passenger step may be deployed.

[0064] In the above embodiment, a cargo ID reader may be provided in the GSE 13, such as a belt loader, a high-lift loader, or a towing tractor used for loading cargo. For example, if the GSE control 11 obtains a list of cargo to be loaded onto the aircraft and attaches a cargo ID, such as a barcode or an IC tag, to the cargo to be loaded onto the aircraft, the cargo ID can be read by the reader of the GSE 13 during cargo loading and compared with the cargo list, preventing the wrong cargo from being loaded.

[0065] In the above embodiment, if multiple ground handling companies are installed within an airport, the GSE control 11 of each of the multiple ground handling companies may work together. For example, if a problem occurs during work by ground handling company A, resulting in a shortage of GSEs 13 or a shortage of workers, making work difficult, the GSE control 11A of ground handling company A may transmit a request to the GSE control 11B of another ground handling company B to inform them of the shortage of GSEs 13 or to request additional workers. In this case, the GSE control 11B may deploy GSEs 13 or workers that are not currently working to ground handling company A as backup. The GSE control 11 may also request backup GSEs or workers from another GSE control at a nearby airport.

[0066] In the above embodiment, if there are multiple waiting locations for GSE 13 and workers within the airport, GSE control 11 may optimize the deployment situation when creating a schedule based on the locations of runways 3 and gates 4 where aircraft 100 arrive and depart. For example, when GSE control 11 creates a work schedule, GSE 13 and workers may be deployed from the waiting location closest to runway 3 and gate 4 where aircraft 100 arrive and depart.

[0067] In the above embodiment, the GSE 13 may be autonomous or remotely controlled. In the autonomous driving mode, the GSE 13 may move to a work site, carrying a worker if necessary, and perform work according to a schedule and route received from the GSE control unit 11. In the remote driving mode, the GSE control unit 11 may transmit the schedule and route to a remote control console or worker terminal of a worker who remotely operates the GSE 13, and the worker may operate the GSE 13 according to instructions from the GSE control unit 11.

[0068] In the above embodiment, a work vehicle is exemplified as the GSE 13, but the GSE 13 also includes ground support equipment other than a work vehicle. In other words, the GSE control 11 may manage all ground support equipment that supports the operation of the aircraft 100. [Explanation of symbols]
