Hereinafter, a work plan change device, a work plan change system, a storage device, a management device, and a work plan change program according to an embodiment will be described in detail based on the drawings.

Embodiment 1.
FIG. 1 is an example of a configuration diagram of a work plan change system 10 according to the first embodiment. The work plan change system 10 is a system that changes the work plan of workers at an airport.

The work plan change system 10 includes a work plan change device 11, a storage device 12, and a management device 13. The work plan changing device 11, the storage device 12, and the management device 13 are connected to a network. The work plan change device 11, the storage device 12, and the management device 13 exchange information with each other via a network. In the first embodiment, the network is, for example, a WAN (Wide Area Network) such as the Internet, but may also be a LAN (Local Area Network).

The work plan change device 11 is a device that changes the work plan of workers at the airport. The work plan change device 11 is operated, for example, by a business operator that operates turnaround operations at an airport. The work plan change device 11 includes a parking schedule input section 21, a movement information storage section 22, a worker information storage section 23, a necessary qualification information storage section 24, a work plan planning section 25, and a work progress information input section. 26, a positioning information input section 27, and a work plan input section 28.

The parking schedule input unit 21 inputs a parking schedule including parking times of aircraft at a plurality of parking lots from the parking schedule output unit 42 of the storage device 12. The parking time includes at least one of the parking start time and the parking end time.

The movement information storage unit 22 stores movement information. The movement information is information regarding the movement of a worker from one of the plurality of aprons to another apron. The movement information is information about the time required to move between parking lots or information about the distance between parking lots.

The worker information storage unit 23 stores worker information that is information regarding worker qualifications and the like.

The necessary qualification information storage unit 24 stores necessary qualification information, which is information that associates work on the tarmac with qualifications required for that work.

The work plan planning section 25 receives the parking schedule from the parking schedule input section 21 , movement information from the movement information storage section 22 , worker information from the worker information storage section 23 , and necessary qualification information storage section 24 . Develop a work plan for workers who will carry out work at the airport based on the required qualification information from For example, if the work plan is for one day, the work planning unit 25 creates the work plan before starting the work for that day. In the example shown in FIG. 1, the work plan planning unit 25 is included in the work plan change device 11, but it does not need to be included in the work plan change device 11. In this case, a work plan manually drawn up in advance by an operator who coordinates the work is input to the work plan changing device 11.

The work progress information input unit 26 inputs work progress information indicating the progress of work at the airport from the work progress information output unit 53 of the management device 13.

The positioning information input unit 27 inputs positioning information that is position information of workers and equipment from the positioning information output unit 55 of the management device 13. The positioning information only needs to include at least the worker's position information.

The work plan input unit 28 inputs the latest work plan from the work plan output unit 57 of the management device 13. If the work plan changing unit 31 has changed the work plan for the first time, the latest work plan is the plan drawn up by the work plan planning unit 25. Further, when the work plan changing unit 31 changes the work plan for the second time or later, the latest work plan is the plan that was changed by the work plan changing unit 31 one time before. That is, the latest work plan is a plan managed by the work plan management unit 56 of the management device 13, which will be described later, and is a plan currently being used as a worker's work plan.

Further, the work plan change device 11 includes a calculation section 29, an estimation section 30, a work plan change section 31, and a work plan output section 32.

The calculation unit 29 calculates the work delay time based on the work progress information from the work progress information input unit 26. The calculation unit 29 calculates the delay time of the work due to the late arrival of the aircraft or the delay time due to the delay of the work itself. The calculation unit 29 outputs a result obtained by adding a parking schedule ID and a delay factor, which will be described later, to the delay time. The calculation results will be explained in detail later using FIG. 9. The delay time is the difference between the scheduled work start time and the work start time. Further, the delay time may be the difference between the scheduled work end time and the work end time, or the difference between the scheduled work end time and the work end time requested by the airline.

The estimating unit 30 generates information for specifying the aircraft parking schedule affected by the work delay based on at least the delay time among the calculation results from the calculation unit 29 and the aircraft parking schedule from the aircraft parking schedule input unit 21. Estimate and use as estimated information. If the delay time from the calculation unit 29 is zero, the estimation unit 30 does not need to estimate information that specifies the parking schedule affected by the delay. The estimation unit 30 calculates the delay time from the calculation unit 29, the parking schedule from the parking schedule input unit 21, the movement information from the movement information storage unit 22, and the work progress information from the work progress information input unit 26. , and the positioning information from the positioning information input unit 27, in the work plan from the work plan input unit 28, information for specifying the parking schedule that is affected by delays is estimated. Here, the information specifying the aircraft parking schedule is information that has a one-to-one correspondence with the aircraft parking schedule, and is, for example, an identifier of the aircraft parking schedule. The identifier of the parking schedule corresponds to the parking schedule ID, which will be explained later.

The estimating unit 30 may estimate information specifying the parking schedule affected by the delay based only on the delay time calculated by the calculating unit 29. Further, the estimating unit 30 may estimate information specifying the parking schedule affected by the delay based not only on the delay time calculated by the calculating unit 29 but also on other information. The other information is, for example, a worker's schedule in the latest work plan. Even if a worker's work is delayed, if the worker has no plans to perform another task after that, the worker will not necessarily be affected by the delay. By using not only the delay time but also other information, the estimation unit 30 can accurately estimate information that specifies the parking schedule that is affected by the delay.

The work plan change unit 31 changes the work plan input from the work plan input unit 28 based on the estimation information from the estimation unit 30. The work plan changing unit 31 inputs the estimated information from the estimating unit 30, the parking schedule from the parking schedule input unit 21, the movement information from the movement information storage unit 22, and the worker information from the worker information storage unit 23. The work plan from the work plan input section 28 may be changed based on the required qualification information from the necessary qualification information storage section 24 and the positioning information from the positioning information input section 27.

The work plan change unit 31 changes the work plan of the worker who will perform the work at the airport for the work affected by the delay. Work affected by delays is work that is linked to information that specifies aircraft parking schedules that are affected by delays. Note that the work plan changing unit 31 changes the work plan based on predetermined constraints. For example, the constraint conditions are: the amount of change from the work plan drawn up by the work plan planning unit 25 is to be less than or equal to a predetermined amount; the amount of change from the latest work plan from the work plan input unit 28 is to be less than or equal to a predetermined amount; The maximum number of overtime hours to be allocated to a given number of workers must be less than or equal to a predetermined value, the maximum overtime hours must be less than or equal to a predetermined time in order to reduce the imbalance in overtime hours for all workers, and the travel time between the aprons for which they are responsible must be a predetermined amount of time. Examples include the following.

The work plan output unit 32 outputs the work plan from the work plan planning unit 25 or the work plan from the work plan changing unit 31 to the work plan input unit 51 of the management device 13. Specifically, if the work plan changing unit 31 has not changed the work plan, the work plan output unit 32 outputs the work plan created by the work plan planning unit 25. When the work plan change unit 31 changes the work plan, the work plan output unit 32 outputs the work plan changed by the work plan change unit 31.

The storage device 12 is a device that stores information used when the work plan change device 11 changes the work plan of workers at the airport. The storage device 12 is operated, for example, by a company that provides transportation by aircraft. The storage device 12 includes a parking schedule storage section 41 and a parking schedule output section 42.

The parking schedule storage unit 41 stores the parking schedule. The parking schedule is information used in planning performed by the work plan planning section 25, estimation performed by the estimating section 30, and modification performed by the work plan changing section 31. Specifically, the parking schedule is information used in formulating a work plan, calculating delay time, estimating information that specifies the parking schedule affected by the delay, and changing the work plan.

The aircraft parking schedule output unit 42 outputs the aircraft parking schedule from the aircraft parking schedule storage unit 41 to the aircraft parking schedule input unit 21 of the work plan changing device 11.

The management device 13 is a device that manages information used when the work plan change device 11 changes the work plan of workers at the airport. The management device 13 is operated, for example, by a business operator that operates airport turnaround services. The management device 13 includes a work plan input section 51, a work progress information management section 52, a work progress information output section 53, a positioning information management section 54, a positioning information output section 55, a work plan management section 56, and a work plan management section 56. A plan output unit 57 is provided.

The work plan input unit 51 inputs a work plan from the work plan output unit 32 of the work plan change device 11.

The work progress information management unit 52 manages work progress information. The work progress information is information used in the calculation performed by the calculation unit 29 and the estimation performed by the estimation unit 30. Specifically, the work progress information is information used to calculate the delay time and estimate information that specifies the parking schedule that is affected by the work delay.

The work progress information output unit 53 outputs the work progress information from the work progress information management unit 52 to the work progress information input unit 26 of the work plan change device 11.

The positioning information management unit 54 manages positioning information. The positioning information is information used in the estimation performed by the estimating section 30 and the modification performed by the work plan changing section 31. Specifically, the positioning information is information used for estimating information that identifies affected aircraft parking schedules and for changing work plans.

The positioning information output unit 55 outputs the positioning information from the positioning information management unit 54 to the positioning information input unit 27 of the work plan changing device 11.

The work plan management unit 56 manages the work plan from the work plan input unit 51.

The work plan output unit 57 outputs the work plan from the work plan management unit 56 to the work plan input unit 28 of the work plan change device 11.

Next, details of various information and work plans according to the first embodiment will be explained using FIGS. 2 to 10. FIG. 2 is an example of an aircraft parking schedule stored in the aircraft parking schedule storage unit 41 of the storage device 12 according to the first embodiment. The parking schedule includes the parking schedule ID, aircraft number, aircraft type, work type, parking lot number, arrival flight number, parking start time, parking end time, and departure time. It includes the flight number and update time.

The parking schedule ID is an identifier of the parking schedule. The aircraft number is a number that uniquely indicates a parked aircraft. The aircraft type is the type of aircraft to be parked. The work type is a work ID set for a parked aircraft. The parking lot number is a number indicating the location where the aircraft is parked. The flight number at the time of arrival is the flight number when the aircraft arrives at the airport and starts parking. The parking start time is the time when the aircraft arrives and stops at the apron. The parking end time is the time when the aircraft starts moving again to leave the parking lot for takeoff. The departure flight number is the flight number when the aircraft finishes parking and leaves the airport. The update time is the time when the parking schedule storage unit 41 updates the parking schedule depending on the flight status of the aircraft.

In the example shown in FIG. 2, the parking lot with the parking lot number "1" corresponding to the parking schedule ID "00001" represents the "first parking lot." Further, the parking lot with the parking lot number "2" corresponding to the parking schedule ID "00002" represents the "second parking lot".

The work type corresponding to the aircraft parking schedule ID may be one such as the aircraft parking schedule ID "00001", or may be multiple such as the aircraft parking schedule ID "00002".

FIG. 3 is an example of movement information stored in the movement information storage unit 22 of the work plan changing device 11 according to the first embodiment. The movement information includes information on the travel time required for a worker to move between one apron and each other apron for a plurality of aprons. In addition, in the example shown in FIG. 3, information on the travel time required for movement between the apron and the cargo handling area, and information on the travel time required for movement between one cargo handling area and another cargo handling area. Also included.

Travel time is, for example, the standard amount of time it takes for a worker to travel by foot or car from a starting point, such as an apron or cargo handling area, to a destination point, such as an apron or cargo handling area. Time. When a worker performs work using equipment at a moving destination, the travel time may be a standard time required for the worker to move using the equipment. In this case, considering the case where the moving speed differs for each piece of equipment, the movement information storage unit 22 may store movement information for each of the plurality of pieces of equipment. Movement information is not limited to information on travel time, but is information on travel distance, which is the distance from the apron or cargo handling area that is the source point to the apron or cargo handling area that is the destination point. Good too. In this case, the moving distance is calculated by multiplying the moving speed by the moving time.

FIG. 4 is an example of worker information stored in the worker information storage unit 23 of the work plan changing device 11 according to the first embodiment. The worker information includes a worker ID and information on whether the worker has each qualification.

The worker ID is an identifier that uniquely indicates a worker. Information on whether or not each qualification is held is represented by "T" and "F". "T" means that the person has a qualification, and "F" means that he or she does not have a qualification. In the example shown in FIG. 4, the worker with worker ID "a0010" has qualification 1 but does not have qualification 2. Qualifications here indicate whether or not the person is capable of performing the various incidental tasks that make up the ground work.

FIG. 5 is an example of necessary qualification information stored in the necessary qualification information storage unit 24 of the work plan changing device 11 according to the first embodiment. The required qualification information includes the type of work and information as to whether each qualification is required. That is, the required qualification information is information indicating which qualification is required for the type of work set for the parked aircraft.

Information on whether each qualification is required is represented by "T" and "F". "T" means qualification required; "F" means no qualification required. In the example shown in FIG. 5, the work of work type "OP001" requires qualification 1 and does not require qualification 2. Therefore, a worker who has at least qualification 1 can perform the work of the work type "OP001". Further, a worker who has at least Qualification 1 and Qualification 2 can independently perform the work of the work type "OP002". The present invention is not limited to this, and for example, a worker who only has qualification 1 and a worker who only has qualification 2 may be able to jointly perform work of work type "OP002."

FIG. 6 is an example of a work plan drawn up by the work plan planning unit 25 of the work plan change device 11 according to the first embodiment. FIG. 6 is an example of a work plan for a certain day. The work plan includes a worker ID, a work start time, a work end time, a work type, a qualification, a work place (starting point), a work place (end point), and a parking schedule ID.

The work start time is the time at which the worker corresponding to the worker ID should start work. The work end time is the time at which the worker corresponding to the worker ID should finish the work. Qualifications are qualifications required for work. Qualification "N/A" means that the qualification is not required for the relevant work. Here, there is not a one-to-one correspondence between work type and qualification. In the example shown in FIG. 6, the work of work type "OP042" requires qualification 20, but qualification 21 is also required, for example.

The work location (starting point) is the location where work corresponding to the work type is performed. Alternatively, the work location (starting point) is the starting point when the work corresponding to the work type involves movement. The work location (end point) is the end point of the work corresponding to the work type, if the work involves movement. The work location (end point) "N/A" means that the work corresponds to the work type and does not involve movement. The parking schedule ID is the ID of the parking schedule. The parking schedule ID "N/A" means that the schedule does not depend on work at a specific parking lot. In the example shown in FIG. 6, the worker corresponding to the worker ID "a0020" only moves between aprons and does not work on a specific apron.

In the example shown in FIG. 6, the worker corresponding to the worker ID "a0010" is assigned to the sixth parking lot from 10:40 to 10:50 based on the parking schedule with the parking schedule ID "00039." Loading and unloading work will be carried out at the airport. The worker corresponding to the worker ID "a0011" will move from the 3rd parking lot to the 8th cargo handling area between 11:00 and 11:10 based on the parking schedule with the aircraft parking schedule ID 00015. Transport cargo to. The worker corresponding to the worker ID "a0020" moves from the fifth tarmac to the second tarmac from 12:10 to 12:25.

FIG. 7 is an example of work progress information managed by the work progress information management unit 52 of the management device 13 according to the first embodiment. The work progress information includes the aircraft parking schedule ID, scheduled work start time, work start time, scheduled work end time, work end time, work end time required by the airline, and update time. included.

The scheduled work start time is the scheduled time when the work based on the aircraft parking schedule corresponding to the aircraft parking schedule ID is scheduled to start. The work start time is the time when the work actually started. The scheduled work end time is the scheduled time when the work based on the aircraft parking schedule corresponding to the aircraft parking schedule ID is scheduled to end. Note that if the work start time changes from the scheduled work start time, the scheduled work end time is changed based on the amount of change between the scheduled work start time and the work start time. In the example shown in FIG. 7, the scheduled start time of the work based on the aircraft parking schedule corresponding to the aircraft parking schedule ID "00002" is 14:00, whereas the work start time is 14:10. In this case, the work started 10 minutes later than scheduled. As a result, the scheduled work end time has been changed to 14:50. If the work start time is 14:00 as scheduled, the scheduled work end time is 14:40.

The work end time is the time when the work was completed. If the work has not been completed, the work end time will be left blank. The work completion time required of the airline is the work completion time that must be observed in order for the relevant aircraft to depart again. The update time is the time when the work progress information management unit 52 updates the work progress information according to the work progress status.

FIG. 8 is an example of positioning information managed by the positioning information management unit 54 of the management device 13 according to the first embodiment. The positioning information includes a worker ID or equipment ID, a position (nearest work place), and an update time.

The equipment ID is an identifier given to each of a plurality of equipment used for ground work at the airport. The position (nearest work place) is the position of the worker corresponding to the worker ID or the nearest work place. The location (nearest work location) may be the location of the equipment corresponding to the equipment ID or the closest work location. The position (nearest work place) may be detected by a GPS (Global Positioning System) not shown, or may be detected by a camera (not shown) attached to a predetermined location. Detection methods are not limited to these. The update time is the time when the positioning information management unit 54 updates the position of the worker or the equipment.

FIG. 9 is an example of calculation results by the calculation unit 29 of the work plan change device 11 according to the first embodiment and estimation information estimated by the estimation unit 30 of the work plan change device 11. The calculation result includes the parking schedule ID, delay factor, and delay time. The estimated information includes the parking schedule ID of the parking schedule affected by the delay.

A delay factor is a factor that caused a delay in work. The delay time is a delay time corresponding to a delay factor. The parking schedule ID of the parking schedule affected by the delay is an identifier of the parking schedule affected by the delay. The parking schedule ID "N/A" of the parking schedule affected by the delay means that there is no parking schedule ID of the parking schedule affected by the delay.

In the example shown in FIG. 9, the work start time for the work corresponding to the parking schedule ID "00042" is delayed by 20 minutes. As a result, the estimation unit 30 estimates that the parking schedule IDs "00042" and "00051" are affected by the delay. Specifically, the estimating unit 30 estimates that the tasks corresponding to the parking schedule IDs "00042" and "00051" will be affected by the delay. Here, the reason why the parking schedule ID "00042" is presumed to be affected by the delay is, for example, that there are multiple tasks corresponding to the parking schedule ID "00042" and the start time of one of them is delayed. This is because the rest of the work will be affected. Furthermore, the reason why it is assumed that the aircraft parking schedule ID "00051" is affected by the delay is that, for example, the worker who performs the work corresponding to the aircraft parking schedule ID "00042" This is because when the work is continued, the start time of the work corresponding to the parking schedule ID "00051" is also delayed.

Furthermore, the work corresponding to the parking schedule ID "00008" has a 15-minute delay in the work end time. As a result, the estimating unit 30 estimates that the parking schedule ID "00055" will be affected by the delay. The reason why it is assumed that the aircraft parking schedule ID "00055" is affected by delays is that, for example, after the work corresponding to the aircraft parking schedule ID "00008", the work corresponding to the aircraft parking schedule ID "00055" is performed on the same tarmac. Because it is done.

Additionally, the work start time for the work corresponding to the parking schedule ID "00039" is delayed by 5 minutes. As a result, the estimating unit 30 estimates that the parking schedule ID "00039" will be affected by the delay.

Additionally, the work corresponding to the parking schedule ID "00045" has a 2-minute delay in the work end time. However, the estimation unit 30 estimates that there is no parking schedule ID that is affected by the delay.

FIG. 10 is an example of a work plan after being changed by the work plan changing unit 31 of the work plan changing device 11 according to the first embodiment. As in Figure 6, the work plan includes the worker ID, work start time, work end time, work type, qualification, work location (starting point), work location (end point), and parking schedule ID. and is included.

In the example shown in FIG. 10, the work start time of the worker corresponding to worker ID "a0010" has been changed from 10:40 to 10:45, and the work start time of the worker corresponding to worker ID "a0032" has been changed from 10:40 to 10:45. This differs from FIG. 6 in that a work plan has been added. This is because, in the work progress information shown in FIG. 7, the start time of the work corresponding to the parking schedule ID "00039" was delayed by 5 minutes. Thereby, as shown in FIG. 9, the estimation unit 30 estimates the parking schedule ID "00039" as the estimation information.

In the example shown in FIG. 10, in addition to the worker corresponding to the worker ID "a0010", the worker corresponding to the worker ID "a0032" corresponds to the work type "OP032" with the parking schedule ID "00039". By performing the work, the work plan will be changed to make up for the delay in starting work. Note that the work corresponding to the work type "OP032" with the parking schedule ID "00039" requires the possession of qualification 1, and the worker corresponding to the worker ID "a0010" previously assigned to this work is Holds qualification 1 as shown in Figure 6. Therefore, the worker corresponding to the newly added worker ID "a0032" does not necessarily need to have Qualification 1. It is desirable that the additional worker who performs the work corresponding to the work type "OP032" be close to the 6th apron, which is the work place (starting point) for loading and unloading. Whether the distance is short can be determined based on the positioning information from the positioning information input section 27. Note that the position of the worker, which is an additional factor, can be estimated not only from the positioning information but also from the work location (starting point) or work location (end point) of the latest work plan.

In the above, the work plan for the work type "OP032" with the parking schedule ID "00039" is changed, but if there is another work corresponding to the parking schedule ID "00039", the work plan with the worker ID "a0032" is The work plan may be changed so that the worker corresponding to the work type "OP032" performs work other than the work corresponding to the work type "OP032".

Additionally, not only the worker corresponding to the worker ID "a0032" but also other workers may change their work plans to perform the work corresponding to the work type "OP032" with the parking schedule ID "00039". . In this case, it is desirable to have a worker who is close to the No. 6 parking lot, which is the work place (starting point) for loading and unloading. Furthermore, when worker ID "a0032" drives the equipment to the sixth parking lot, it is desirable that the worker be able to board the equipment on the way to the sixth parking lot.

Next, the operation of the work plan change system 10 will be explained. FIG. 11 is a flowchart illustrating an example of the operation procedure of the work plan change system 10 according to the first embodiment. As a premise for the operation procedure described below, the parking schedule is stored in the parking schedule storage section 41. The movement information storage section 22 stores movement information. The worker information storage unit 23 stores worker information. The necessary qualification information storage section 24 stores necessary qualification information. The work progress information management section 52 manages work progress information. The positioning information management section 54 manages positioning information. The work plan management unit 56 manages the latest work plans that have been drawn up or changed in advance.

In step ST1, the parking schedule output unit 42 of the storage device 12 determines whether the parking schedule shown in FIG. 2 has been updated. Specifically, the parking schedule output unit 42 determines whether the parking schedule has been updated based on the update time of the parking schedule. Further, the work progress information output unit 53 of the management device 13 determines whether the work progress information shown in FIG. 7 has been updated. Specifically, the work progress information output unit 53 determines whether the work progress information has been updated based on the update time of the work progress information. If the determination in step ST1 is Yes, that is, if at least one of the determinations made by the parking schedule output unit 42 or the work progress information output unit 53 is Yes, the process proceeds to step ST2. If the determination in step ST1 is No, that is, if both the determination made by the parking schedule output unit 42 and the determination made by the work progress information output unit 53 are No, the work plan changing device 11 repeats the process of step ST1. conduct.

In step ST2, if it is determined that the aircraft parking schedule has been updated, the aircraft parking schedule input unit 21 of the work plan changing device 11 transfers the updated aircraft parking schedule to the aircraft parking schedule output unit of the storage device 12. 42. If it is determined that the work progress information has been updated, the work progress information input unit 26 of the work plan changing device 11 receives the updated work progress information from the work progress information output unit 53 of the management device 13. .

In step ST3, the positioning information output unit 55 of the management device 13 determines whether the positioning information shown in FIG. 8 has been updated. Specifically, the positioning information output unit 55 determines whether the positioning information has been updated based on the update time of the positioning information. If the determination in step ST3 is Yes, the process proceeds to step ST4. If the determination in step ST3 is No, the process proceeds to step ST5.

In step ST4, the positioning information input unit 27 of the work plan changing device 11 receives the updated positioning information from the positioning information output unit 55 of the management device 13.

In step ST5, the calculation unit 29 of the work plan changing device 11 calculates the delay time based on the work progress information.

In step ST6, the estimating unit 30 of the work plan changing device 11 estimates the parking schedule ID of the parking schedule affected by the delay in the work plan from the work plan input unit 28. The estimating unit 30 of the work plan changing device 11 estimates the influence of delays on the work plan from the work plan input unit 28 based on the delay time, parking schedule, work progress information, movement information, and positioning information. The parking schedule ID of the parking schedule that is received is estimated. The estimation unit 30 may notify, for example, the operator who coordinates the work of the parking schedule ID of the parking schedule affected by the delay as an alert.

In step ST8, the work plan changing unit 31 of the work plan changing device 11 changes the work plan for the aircraft parking schedule ID of the aircraft parking schedule affected by the delay, based on the estimation information. Alternatively, the work plan change unit 31 of the work plan change device 11 is affected by the delay based on the estimated information, parking schedule, movement information, worker information, necessary qualification information, and positioning information.

With the above, the work plan change system 10 ends the operation according to the procedure shown in FIG. 11.

Note that in the procedure shown in FIG. 11, if neither the parking schedule nor the work progress information is updated, the processes from step ST2 onwards are not performed. The present invention is not limited to this, and the processing from step ST2 onward may be performed at a predetermined cycle regardless of whether the information has been updated. In this case, the process of step ST1 is not performed. Moreover, in step ST2, not only the updated information is acquired, but all information, that is, the parking schedule, movement information, worker information, necessary qualification information, work progress information, and positioning information are acquired.

According to the first embodiment, the calculation unit 29 calculates the delay time based on the work progress information. The estimation unit 30 estimates the parking schedule ID of the parking schedule affected by the delay based on the delay time and the parking schedule, and uses the estimated information as estimated information. The work plan changing unit 31 changes the work plan based on the estimated information. Thereby, it is possible to appropriately determine whether or not the work plan needs to be changed, it is possible to specify the parts to be changed, and it is possible to efficiently change the work plan.

The estimating unit 30 estimates the parking schedule ID of the parking schedule affected by the delay, also taking movement information into consideration. Thereby, the estimated information can be estimated with high accuracy. The work plan changing unit 31 changes the work plan while also considering movement information.

Embodiment 2.
In the first embodiment, the work plan change unit 31 changes the work plan by any method based on the estimated information, the parking schedule, the movement information, the worker information, the necessary qualification information, and the positioning information. change. On the other hand, in the second embodiment, the work plan changing unit 31 changes the work plan using, for example, machine learning. Note that the configuration diagram of the work plan change system 10 according to the second embodiment is the same as the configuration diagram shown in FIG.

We will explain how to change work plans using machine learning. FIG. 12 is an example of a configuration diagram of the work plan changing unit 70 when machine learning is used in the second embodiment. The work plan changing unit 70 is an example of the work plan changing unit 31 that changes the work plan using machine learning.

The work plan change unit 70 includes a learning device 71, an inference device 72, and a learned model storage unit 73. The learning device 71 learns the work plan. The learning device 71 outputs a learned model that is a result of learning. The learned model storage unit 73 stores learned models. The inference device 72 reads out a learned model for inferring a work plan from the learned model storage unit 73. The inference device 72 outputs an inference result as a changed work plan by inputting inference data to the trained model.

FIG. 13 is an example of a configuration diagram of the learning device 71 included in the work plan changing section 70 according to the second embodiment. The learning device 71 includes a data acquisition section 74 and a model generation section 75. The data acquisition unit 74 acquires learning data and creates a data set in which the learning data is combined. The learning data includes the latest work plan, estimated information, parking schedule, work progress information, movement information, worker information, required qualification information, and positioning information.

The model generation unit 75 generates a learned model using the learning data. The model generation unit 75 generates a learned model that infers a work plan from the latest work plan, estimated information, parking schedule, work progress information, movement information, worker information, required qualification information, and positioning information.

As the learning algorithm used by the model generation unit 75, a known algorithm such as supervised learning, unsupervised learning, or reinforcement learning can be used. As an example, a case will be described in which reinforcement learning is applied to the learning algorithm used by the model generation unit 65. Reinforcement learning is a method in which an agent in an environment observes the current state and decides what action to take. Agents obtain rewards from the environment by selecting actions, and through a series of actions, they learn strategies that will yield the most rewards. Q learning and TD (Temporal Difference) learning are known as typical methods of reinforcement learning. For example, in the case of Q-learning, the action value table, which is a general update formula for the action value function Q(s, a), is expressed by the following equation (1). The action value function Q(s, a) represents the action value Q, which is the value of the action of selecting action "a" under environment "s".

In equation (1), "s _t " represents the environment at time "t". “a _t ” represents an action at time “t”. The action "a _t " changes the environment to "s _t+1 ". “r _t+1 ” represents the reward received as a result of the change in the environment. "γ" represents a discount rate. "α" represents a learning coefficient. The work plan becomes the environment "s _t ". The method of updating the work plan in the model generation unit 65 or the point of updating the work plan is the action "a _t ". The latest work plan, estimated information, parking schedule, work progress information, movement information, worker information, required qualification information, and positioning information are the data referenced when updating the work plan.

The update formula expressed by equation (1) is that if the action value of the best action "a" at time "t+1" is greater than the action value Q of action "a" executed at time "t", then the action Increase the value Q, and in the opposite case, decrease the action value Q. In other words, the action value function Q(s, a) is updated so that the action value Q of action "a" at time "t" approaches the best action value at time "t+1". As a result, the best action value in a certain environment is sequentially propagated to the action value in the previous environment.

The model generation unit 75 includes a reward calculation unit 76 and a function update unit 77. The remuneration calculation unit 76 calculates remuneration based on the data set. The function update unit 77 updates the function for determining the work plan according to the remuneration calculated by the remuneration calculation unit 76.

Specifically, the remuneration calculation unit 76 calculates the remuneration "r" based on the value of the objective function whose index is the efficiency of the work plan. Efficiency in work planning refers to the small amount of changes from the latest work plan, the small number of spare workers assigned to the work, the small imbalance in overtime hours of all workers, and the ease of movement between the tarmacs for which they are responsible. This is due to the small number of For example, if the value of the objective function changes in a direction that improves the efficiency of the work plan, the reward calculation unit 76 increases the reward "r". The reward calculation unit 76 increases the reward "r" by giving a reward value of "1". Note that the reward value is not limited to "1". If the value of the objective function changes in a direction that reduces the efficiency of the work plan, the reward calculation unit 76 decreases the reward "r". The reward calculation unit 76 reduces the reward "r" by giving a reward value of "-1". Note that the reward value is not limited to "-1".

The function update unit 77 updates a function that is a model for determining a work plan according to the remuneration calculated by the remuneration calculation unit 76. Updating the function can be done according to the data set, for example by updating the action value table. The action value table is a data set in which arbitrary actions and their action values are associated with each other and stored in a table format. For example, in the case of Q learning, the action value function Q (s _t , a _t ) expressed by the above equation (1) is used as a function for determining estimated information.

Up to this point, a case has been described in which reinforcement learning is applied to the learning algorithm used by the model generation unit 75, but learning other than reinforcement learning may be applied to the learning algorithm. The model generation unit 75 may perform machine learning using a known learning algorithm other than reinforcement learning, such as deep learning, neural network, genetic programming, inductive logic programming, or support vector machine.

FIG. 14 is an example of a configuration diagram of the inference device 72 included in the work plan change unit 70 according to the second embodiment. The inference device 72 infers a work plan based on the inference data.

The inference device 72 includes a data acquisition section 78 and an inference section 79. The data acquisition unit 78 acquires inference data. The inference data includes the latest work plan, estimated information, parking schedule, work progress information, movement information, worker information, required qualification information, and positioning information.

The inference unit 79 reads out the learned model generated by the learning device 71 from the learned model storage unit 73. The inference unit 79 infers a work plan by inputting inference data to the trained model. The inference unit 79 outputs the inference result as a changed work plan.

In this way, the work plan changing unit 70 changes the work plan using machine learning. Thereby, the work plan changing device 11 can change the work plan with high accuracy.

Note that the learning device 71 and the inference device 72 are provided in the work plan changing device 11, but are not limited thereto. The learning device 71 and the reasoning device 72 may be provided outside the work plan changing device 11. In this case, the learning device 71 and the inference device 72 may be connected to the work plan changing device 11 via a network. The learning device 71 and the inference device 72 may exist on a cloud server.
