Summary of the Invention

Problems to be Solved by the Invention

[0004] According to the conventional technology described in Patent Document 1, when the created vehicle maintenance plan involves train delays and the impact of the delays spreads to subsequent trains, the dispatcher who operates the train operation management support device requests the vehicle maintenance plan creator to replan. The vehicle maintenance plan creator who receives the request from the dispatcher considers omitting part of the work shown in the vehicle maintenance plan, and specifies the working time in the case where part of the work is omitted, and causes the vehicle maintenance plan creation support device to create the vehicle maintenance plan again. Thus, according to the conventional technology described in Patent Document 1, the dispatcher determines the part where a change is desired in the vehicle maintenance plan, and the vehicle maintenance plan creator determines the mode of change of the vehicle maintenance plan. For this reason, there is a problem that it may be difficult to appropriately change the work plan depending on the judgments of the dispatcher and the vehicle maintenance plan creator.

[0005] This disclosure is made in view of the above, and aims to provide an information processing device that enables support for appropriately modifying work plans related to the maintenance of railway equipment. [Means for solving the problem]

[0006] To solve the above-mentioned problems and achieve the objectives, the information processing device relating to this disclosure includes a prediction unit that predicts future train schedules and future work status related to railway equipment maintenance based on timetable information showing train operation plans, work plan information showing work plans related to railway equipment maintenance, and operation performance information showing train operation performance; and an operation adjustment plan creation unit that creates an operation adjustment plan including changes to the work plan based on timetable prediction information showing the predicted timetable and work status prediction information showing the predicted work status. [Effects of the Invention]

[0007] The information processing device described herein has the effect of providing support for appropriately modifying work plans related to the maintenance of railway equipment. [Brief explanation of the drawing]

[0009] The information processing device, command support system, information processing method, and program according to the embodiment will be described in detail below with reference to the drawings.

[0010] Embodiment 1. Figure 1 shows an example configuration of the command support system 10 according to Embodiment 1. The command support system 10 is a system that supports command operations in train operation through information processing. When the train schedule is disrupted, the command support system 10 predicts the future schedule and the future status of operations, and based on the prediction results, comprehensively proposes changes to the schedule, changes to the operation of trains, changes to the duties of crew members, and changes to the work plan.

[0011] The command support system 10 comprises a train operation management device 11 for managing train operations, a work plan management device 12 for managing work plans related to the maintenance of railway equipment, an information processing device 13 for performing information processing, an operation terminal 14 connected to the train operation management device 11 and the information processing device 13, and an operation terminal 15 connected to the work plan management device 12. The operation terminal 14 is responsible for inputting information to the train operation management device 11 and the information processing device 13, respectively, and outputting information from the train operation management device 11 and the information processing device 13, respectively. The operation terminal 15 is responsible for inputting information to the work plan management device 12 and outputting information from the work plan management device 12.

[0012] In Embodiment 1, the train operation management device 11, the information processing device 13, and the operation terminal 14 are installed in a central control center. The operation terminal 14 is operated by a dispatcher located in the central control center. The operation terminal 14 also displays the operating status of each train running on the line, as well as the status of signals installed on the line. The dispatcher monitors the operating status of each train by checking the display on the operation terminal 14 and issues work instructions to the train crew and station staff.

[0013] In Embodiment 1, the work plan management device 12 and the operation terminal 15 are installed in a railway operational organization such as a track maintenance section or a rolling stock depot. The operation terminal 15 is operated by workers involved in on-site work. The operation terminal 15 may also be operated by a person indirectly involved in the work, such as a site supervisor. In the following description, the operation terminal 15 will be assumed to be operated by a worker. The worker creates a work plan by inputting information into the operation terminal 15. In Embodiment 1, the work plan will include a plan for track maintenance work and a plan for maintenance or repair work on the rolling stock that makes up the train.

[0014] The operation management device 11 and the work plan management device 12 are connected to each other via a network. The operation management device 11 and the information processing device 13 are connected to each other via a network. The network is, for example, a WAN (Wide Area Network) such as the Internet, but it may also be a LAN (Local Area Network). The operation management device 11 and the work plan management device 12 transmit and receive information to each other through communication via the network. The operation management device 11 and the information processing device 13 transmit and receive information to each other through communication via the network.

[0015] The operation management device 11 manages the train operation plan schedule information and the train operation actual performance information. The operation management device 11 holds the schedule information, the operation actual performance information, and the work plan information indicating the work plan related to the maintenance of railway facilities. The operation management device 11 sends the schedule information, the operation actual performance information, and the work plan information to the information processing device 13.

[0016] The work plan management device 12 holds the work plan information created by the worker and manages the work plan information. The operation terminal 15 displays the work plan information held in the work plan management device 12. Also, the work plan management device 12 sends the work plan information to the operation management device 11. The work plan management device 12 sends the work plan information to the operation management device 11, for example, at a fixed time every day. The operation management device 11 receives the work plan information from the work plan management device 12 and holds the received work plan information.

[0017] The information processing device 13 creates an operation adjustment plan based on the schedule information, the operation actual performance information, and the work plan information from the operation management device 11. The operation adjustment plan includes schedule change information and work plan change information. The schedule change information is information indicating the change content from the schedule shown in the schedule information. The work plan change information is information indicating the change content from the work plan shown in the work plan information. The operation terminal 14 displays the operation adjustment plan created by the information processing device 13.

[0018] The information processing device 13 sends schedule change information and work plan change information to the operation management device 11. The operation management device 11 updates the schedule information it holds based on the schedule change information from the information processing device 13. The operation management device 11 also sends work plan change information from the information processing device 13 to the work plan management device 12. The work plan management device 12 updates the work plan information it holds based on the work plan change information from the operation management device 11.

[0019] Each of the operation management device 11, the work plan management device 12, and the information processing device 13 is configured by a computer system. Each of the operation management device 11, the work plan management device 12, and the information processing device 13 may be configured by, for example, one or more cloud servers. A cloud server is a server built in a cloud environment that includes computer resources provided on a cloud service platform. However, each of the operation management device 11, the work plan management device 12, and the information processing device 13 may be a server other than a cloud server, for example, an on-premises server.

[0020] Next, an example configuration of the operation management device 11, the work plan management device 12, and the information processing device 13 will be described. Figure 2 is a diagram showing an example configuration of the operation management device 11, the work plan management device 12, and the information processing device 13 that are included in the command support system 10 according to Embodiment 1.

[0021] The operation management device 11 includes an information acquisition unit 21 that acquires information, an information management unit 22 that manages the acquired information, a storage unit 23 that stores the information, and a transmission unit 24 that transmits the information. The operation management device 11 also includes an approval request receiving unit 25 and an approval processing unit 26.

[0022] The information acquisition unit 21 acquires work plan information by receiving it from the work plan management device 12 to the operation management device 11. The information management unit 22 stores the work plan information acquired by the information acquisition unit 21 in the storage unit 23. As a result, the storage unit 23 stores the work plan information. In addition, the storage unit 23 stores timetable information and operation performance information.

[0023] The information acquisition unit 21 acquires the schedule change information and work plan change information by receiving them from the information processing device 13 to the operation management device 11. The information management unit 22 modifies the contents of the schedule information stored in the storage unit 23 based on the schedule change information acquired by the information acquisition unit 21. As a result, the information management unit 22 updates the schedule information held in the operation management device 11. The information management unit 22 sends the work plan change information acquired by the information acquisition unit 21 to the transmission unit 24. The transmission unit 24 sends the work plan change information to the work plan management device 12. The approval request receiving unit 25 and the approval processing unit 26 will be described later.

[0024] The work plan management device 12 includes an information acquisition unit 31 for acquiring information, a work plan management unit 32 for managing work plan information, a storage unit 33 for storing information, and a transmission unit 34 for transmitting information. The work plan management device 12 also includes an approval request receiving unit 35 and an approval result receiving unit 36.

[0025] The memory unit 33 stores the work plan information. The work plan management unit 32 reads the work plan information from the memory unit 33 and sends the read work plan information to the transmission unit 34. The transmission unit 34 sends the work plan information to the operation management device 11.

[0026] The information acquisition unit 31 acquires work plan change information by receiving the work plan change information sent from the operation management device 11 to the work plan management device 12. The work plan management unit 32 modifies the content of the work plan information stored in the storage unit 33 based on the work plan change information acquired by the information acquisition unit 31. As a result, the work plan management unit 32 updates the work plan information held in the work plan management device 12. The work plan management unit 32 sends the updated work plan information to the transmission unit 34. The transmission unit 34 sends the updated work plan information to the operation management device 11.

[0027] When the information acquisition unit 31 acquires work plan change information, the work plan management unit 32 sends the work plan change information to the operation terminal 15 via the transmission unit 34. The operation terminal 15 displays the contents of the work plan change information. The work plan management unit 32 requests the worker's approval for updating the work plan based on the contents displayed on the operation terminal 15 via the operation terminal 15. The worker approves or rejects the work plan update by operating the operation terminal 15. If the work plan update is approved by the worker, the work plan management unit 32 updates the work plan information stored in the storage unit 33.

[0028] When a change to the work plan is desired, the worker instructs the work plan management device 12 to change the work plan via the operation terminal 15. The work plan management unit 32 changes the contents of the work plan information stored in the storage unit 33 in response to the worker's instruction. As a result, the work plan management unit 32 updates the work plan information in response to the worker's instruction. The work plan management unit 32 sends the updated work plan information to the transmission unit 34. The transmission unit 34 sends the updated work plan information to the operation management device 11.

[0029] When work indicated in the work plan is to begin, the worker requests approval to start the work by operating the operation terminal 15. The approval request is entered from the operation terminal 15 to the approval request reception unit 35. The approval request reception unit 35 then receives the approval request to start the work. The approval request reception unit 35 sends a notification of the approval request to the operation management device 11 via the transmission unit 34.

[0030] The approval request receiving unit 25 of the operation management device 11 receives an approval request notification from the work plan management device 12. The approval request receiving unit 25 sends the received approval request notification to the approval processing unit 26. The approval processing unit 26 requests approval from the dispatcher for the start of work via the operation terminal 14. The dispatcher approves or rejects the start of work by operating the operation terminal 14. The approval processing unit 26 sends the approval result, which is information indicating that the start of work has been approved or information indicating that the start of work has been rejected, to the transmission unit 24. The transmission unit 24 transmits the approval result to the work plan management device 12.

[0031] The approval result receiving unit 36 ​​of the work plan management device 12 receives the approval result from the operation management device 11. The approval result receiving unit 36 ​​notifies the worker of the approval result by sending the received approval result to the operation terminal 15 via the transmission unit 34. The work starts when the dispatcher approves the start of the work.

[0032] When a task that has been started is about to be completed, the worker requests approval for the completion of the task by operating the control terminal 15. When a task is completed, the operation management device 11 and the work plan management device 12 perform the same processing as when a task is started. The task is completed when the dispatcher approves the completion of the task.

[0033] The information processing device 13 comprises an information acquisition unit 41 for acquiring information, a prediction unit 42, a train operation plan creation unit 43, and a transmission unit 44. The information acquisition unit 41 acquires timetable information, train operation performance information, and work plan information by receiving timetable information, train operation performance information, and work plan information sent from the train operation management device 11 to the information processing device 13. The information acquisition unit 41 periodically acquires timetable information, train operation performance information, and work plan information.

[0034] The prediction unit 42 receives timetable information, operational performance information, and work plan information acquired by the information acquisition unit 41. The prediction unit 42 also receives vehicle operation information, which shows the operational plan for the vehicles constituting the train, and crew duty information, which shows the duty plan for the crew. Based on the timetable information, operational performance information, work plan information, vehicle operation information, and crew duty information, the prediction unit 42 predicts the future timetable of the train, the future work status related to the maintenance of railway equipment, the future operational status of the vehicles, and the future duty status of the crew. Hereinafter, the prediction process performed by the prediction unit 42 will be referred to as the operation simulation.

[0035] When the operation plan of the vehicles is managed by the operation management device 11, the vehicle operation information is stored in the memory unit 23 of the operation management device 11. In this case, the information acquisition unit 41 acquires the vehicle operation information sent from the operation management device 11 to the information processing unit 13. Alternatively, when the operation plan of the vehicles is managed by a vehicle management device external to the command support system 10, the information acquisition unit 41 acquires the vehicle operation information sent from the vehicle management device to the information processing unit 13. The vehicle operation information acquired by the information acquisition unit 41 is input to the prediction unit 42. Note that the vehicle management device is not shown in the diagram.

[0036] When the crew's work schedule is managed by the operation management device 11, the crew work information is stored in the memory unit 23 of the operation management device 11. In this case, the information acquisition unit 41 acquires the crew work information sent from the operation management device 11 to the information processing device 13. Alternatively, when the crew's work schedule is managed by an external crew work management device of the command support system 10, the information acquisition unit 41 acquires the crew work information sent from the crew work management device to the information processing device 13. The crew work information acquired by the information acquisition unit 41 is input to the prediction unit 42. Note that the illustration of the crew work management device is omitted.

[0037] The prediction unit 42 sends schedule prediction information showing the predicted schedule, work status prediction information showing the predicted work status, vehicle operation prediction information showing the predicted vehicle operation status, and crew work prediction information showing the predicted crew work status to the operation plan creation unit 43.

[0038] The train schedule plan creation unit 43 creates a train schedule plan, including changes to the work plan, based on the timetable forecast information, work status forecast information, vehicle operation forecast information, and crew duty forecast information. Specifically, the train schedule plan creation unit 43 creates several candidate train schedule plans. For each of the candidate plans, the train schedule plan creation unit 43 evaluates the load associated with the change in the operation plan and the load associated with the change in the work plan, operation plan, or duty plan. Based on the evaluation results for each of the candidate plans, the train schedule plan creation unit 43 selects a candidate to be used as the train schedule plan. In this way, the train schedule plan creation unit 43 creates the train schedule plan. The train schedule plan creation unit 43 sends the created train schedule plan to the transmission unit 44. Note that, in the above, the train schedule plan creation unit 43 evaluates the load associated with the change in the operation plan and the load associated with the change in the work plan, operation plan, or duty plan for each of the candidate plans. The operational plan creation unit 43 may evaluate, for each of the multiple candidates, at least one of the burden associated with changing the operational plan and the burden associated with changing the work plan.

[0039] In the following, the burden resulting from changes in the operational plan, or from changes in the work plan, operational plan, or duty plan, will be referred to as change costs. Change costs include expenses, labor, and time costs. Expenses in change costs refer to the additional expenses required due to the change. Labor in change costs refers to the labor of personnel such as workers, crew members, or station staff that is required to be added due to the change. Examples of labor include notifying crew members of changes when the train's arrival platform is changed, and making announcements to inform railway users of the changes. Time costs in change costs include delays in the schedule, delays in work, or waiting times for railway users.

[0040] The Operational Schedule Creation Department 43 calculates the cost of changes for each candidate based on the changes to the operation plan (i.e., the timetable), the work plan, the vehicle operation plan, and the crew duty plan. The Operational Schedule Creation Department 43 selects the candidate with the lowest change cost from among the multiple candidates as the candidate for the operational schedule.

[0041] The transmitting unit 44 sends a proposed train schedule to the operating terminal 14. The operating terminal 14 displays the contents of the proposed train schedule. The operating terminal 14 requests approval from the dispatcher for the proposed train schedule displayed on the operating terminal 14. The dispatcher approves or rejects the proposed train schedule by operating the operating terminal 14. If the train schedule is approved by the dispatcher, the transmitting unit 44 transmits the timetable change information and work plan change information included in the proposed train schedule to the operation management device 11.

[0042] The operational adjustment plan includes vehicle operation change information, which shows the changes from the operational plan indicated in the vehicle operation information. If the vehicle operation plan is managed by the operation management device 11, the transmission unit 44 sends the vehicle operation change information to the operation management device 11. The operation management device 11 updates the vehicle operation information held in the operation management device 11 based on the vehicle operation change information from the information processing device 13. Alternatively, if the vehicle operation plan is managed by the vehicle management device, the transmission unit 44 sends the vehicle operation change information to the vehicle management device. The vehicle management device updates the vehicle operation information held in the vehicle management device based on the vehicle operation change information from the information processing device 13.

[0043] The operational reorganization plan includes crew duty change information, which shows the changes from the duty plan indicated in the crew duty information. If the crew duty plan is managed by the operation management device 11, the transmission unit 44 sends the crew duty change information to the operation management device 11. The operation management device 11 updates the crew duty information held in the operation management device 11 based on the crew duty change information from the information processing device 13. Alternatively, if the crew duty plan is managed by the crew duty management device, the transmission unit 44 sends the crew duty change information to the crew duty management device. The crew duty management device updates the crew duty information held in the crew duty management device based on the crew duty change information from the information processing device 13.

[0044] In the above, it was assumed that one operating terminal 14 was responsible for inputting information to the operation management device 11 and the information processing device 13, and for outputting information from the operation management device 11 and the information processing device 13, respectively. The command support system 10 may also include an operating terminal that is responsible for inputting information to the operation management device 11 and outputting information from the operation management device 11, and an operating terminal that is responsible for inputting information to the information processing device 13 and outputting information from the information processing device 13. In other words, the command support system 10 may include an operating terminal connected to the operation management device 11 and an operating terminal connected to the information processing device 13.

[0045] In the above, the prediction unit 42 is configured to perform an operation simulation based on timetable information, work plan information, operational performance information, vehicle operation information, and crew duty information. The prediction unit 42 may also perform an operation simulation based on information regarding weather or disasters. That is, the prediction unit 42 may predict the future timetable of trains, future work conditions, future vehicle operation conditions, and future crew duty conditions based on timetable information, work plan information, operational performance information, vehicle operation information, crew duty information, and information regarding weather or disasters. Information regarding weather or disasters includes, for example, information indicating sections or time periods where heavy rain, snowfall, or strong winds are expected, information indicating that obstacles that may hinder train operations have been discovered, or information indicating the occurrence of a disaster. The information processing device 13 acquires information regarding weather or disasters from, for example, an external server (not shown) via the information acquisition unit 41. Alternatively, if weather or disaster-related information is stored in the storage unit 23, the information processing device 13 retrieves the weather or disaster-related information from the storage unit 23 via the information retrieval unit 41. This enables the information processing device 13 to propose operational adjustment plans that take into account the effects of weather, disaster prevention, or accident prevention.

[0046] Next, the operation plan created by the operation plan creation unit 43 will be described. Figure 3 is the first diagram illustrating the operation plan created by the operation plan creation unit 43 of the command support system 10 according to Embodiment 1. Figure 4 is the second diagram illustrating the operation plan created by the operation plan creation unit 43 of the command support system 10 according to Embodiment 1.

[0047] Figure 3 shows an example of a graph representing train operations. In the graph shown in Figure 3, the vertical axis represents station names, and the horizontal axis represents time. The graph shown in Figure 3 is displayed on the operating terminal 14. Object 51 represents the current time when the graph shown in Figure 3 is displayed. The dashed line 54 shown in Figure 3 represents the actual timetable, which is the train operation record up to the current time. The dashed line 55 shown in Figure 3 represents the planned timetable, which is the operation plan, i.e., the timetable information. The solid line 56 shown in Figure 3 represents the predicted timetable, which is the future timetable predicted by the prediction unit 42.

[0048] In the example shown in Figure 3, the planned timetable indicates that a train departs Station X before 8:00 and arrives at Station Z at 9:00. Assume that the train was scheduled to depart Station X after a turnaround operation. Furthermore, in the same example, the actual timetable for the train is behind schedule, and at the time it was scheduled to depart Station X, it is traveling from Station Z towards Station X. The actual timetable indicates that the train has arrived at Station Y at the current time.

[0049] The prediction unit 42 creates a predicted timetable for the train based on the train's actual timetable. The predicted timetable shows that, as indicated by the straight line 56 in Figure 3, the train will travel from the current time to station X, and then turn around at station X and travel to station Z.

[0050] Object 52, shown in Figure 3, represents the work plan indicated in the work plan information. This work plan is for work performed between 9:00 and 10:00, and involves closing the tracks between Station Y and Station Z. Vertically, the placement of Object 52 between the scale representing Station Y and the scale representing Station Z indicates that the work section in which the work will be performed is between Station Y and Station Z. Horizontally, the placement of Object 52 between the scale representing 9:00 and the scale representing 10:00 indicates that the work time in which the work will be performed is between 9:00 and 10:00. In addition, the word "Closed" shown with Object 52 in Figure 3 indicates that the work represented by Object 52 involves closing the tracks.

[0051] In the example shown in Figure 3, it has been determined at the present time that the predicted timetable overlaps with the work sections and work times shown in the work plan, and that operational adjustments involving changes to the timetable or work plan are necessary. The operational adjustment proposal creation unit 43 determines that operational adjustments are necessary based on the predicted timetable information and predicted work status information input from the prediction unit 42. Based on this determination, the operational adjustment proposal creation unit 43 creates an operational adjustment proposal.

[0052] In the example shown in Figure 3, it is assumed that the train schedule creation unit 43 has created a train schedule that includes a change to the work plan. That is, the train schedule creation unit 43 creates a train schedule that includes work plan change information. Object 53 shown in Figure 3 represents the revised work plan as indicated in the work plan change information. The revised work plan is for work to be performed between 9:30 and 10:00, and involves closing the tracks between Station X and Station Y. On the operation terminal 14, the display mode is set so that the object 52 representing the work plan before the change and the object 53 representing the work plan after the change can be easily distinguished from each other. For example, objects 52 and 53 are displayed in different colors.

[0053] Figure 4 shows an example of how the contents of the proposed operational adjustments are represented in text. In the example shown in Figure 4, the changes indicated in the operational adjustments are displayed in a pop-up window. This pop-up window is displayed, for example, overlaid on the graph shown in Figure 3.

[0054] In the example shown in Figure 4, the original and modified content are shown for each of the work time, work section, and work content. In the example shown in Figure 4, it is shown that the work time has been changed from 9:00-10:00 to 9:30-10:00, and the work section has been changed from Station Y to Station Z to Station X to Station Y. In addition, in the example shown in Figure 4, it is shown that the work content has been changed from work α, work β, and work γ to work α and work γ. Here, α, β, and γ are the names of the work. The dispatcher can easily understand the content of the operation reorganization plan by displaying it as shown in Figures 3 and 4.

[0055] In the pop-up shown in Figure 4, the "Approve" button is pressed when the dispatcher approves the proposed train schedule shown in the pop-up. The "Cancel" button is pressed when the dispatcher rejects the proposed train schedule shown in the pop-up. The information processing device 13 receives the dispatcher's approval or rejection of the proposed train schedule by displaying these operation buttons on the operation terminal 14.

[0056] Next, the operation procedure of the command support system 10 will be described. Figure 5 is a flowchart showing an example of the operation procedure of the command support system 10 according to Embodiment 1. Here, the operation procedure until work is started according to the updated work plan will be described.

[0057] In step S1, the information acquisition unit 41 of the information processing device 13 acquires timetable information, operational performance information, and work plan information from the operation management device 11. In addition, as described above, the information acquisition unit 41 acquires vehicle operation information and crew duty information.

[0058] In step S2, the prediction unit 42 of the information processing device 13 performs an operation simulation based on the information acquired by the information acquisition unit 41. The prediction unit 42 outputs the results of the operation simulation, namely the schedule prediction information, the work status prediction information, the vehicle operation prediction information, and the crew duty prediction information.

[0059] In step S3, the operation plan creation unit 43 of the information processing device 13 creates an operation plan based on the results of the operation simulation in step S2. The operation plan creation unit 43 creates several candidate operation plans. The operation plan creation unit 43 calculates the change cost for each candidate and selects a candidate to be adopted as the operation plan based on the change cost.

[0060] When the train schedule plan created in step S3 is approved by the dispatcher, in step S4, the transmission unit 44 of the information processing device 13 transmits the schedule change information and the work plan change information to the operation management device 11. The information acquisition unit 21 of the operation management device 11 acquires the schedule change information and the work plan change information included in the train schedule plan.

[0061] In step S5, the information management unit 22 of the operation management device 11 updates the timetable information based on the timetable change information acquired by the information acquisition unit 21. The information management unit 22 also sends the work plan change information acquired by the information acquisition unit 21 to the transmission unit 24. In step S6, the transmission unit 24 of the operation management device 11 transmits the work plan change information to the work plan management device 12.

[0062] The information acquisition unit 31 of the work plan management device 12 acquires work plan change information from the operation management device 11. When the update of the work plan based on the acquired work plan change information is approved by the worker, in step S7, the work plan management unit 32 of the work plan management device 12 updates the work plan based on the work plan change information acquired by the information acquisition unit 31. The work plan management unit 32 sends the updated work plan information to the transmission unit 34. In step S8, the transmission unit 34 of the work plan management device 12 transmits the updated work plan information to the operation management device 11.

[0063] When work indicated in the work plan is to begin, the worker requests approval to start the work by operating the operation terminal 15. The approval request receiving unit 35 receives the approval request to start the work. In step S9, the transmission unit 34 transmits the work commencement approval request to the operation management device 11.

[0064] The approval request receiving unit 25 of the operation management device 11 receives an approval request from the work plan management device 12. In step S10, the approval processing unit 26 of the operation management device 11 performs the work commencement approval process. As part of the approval process, the approval processing unit 26 requests approval for the commencement of work from the dispatcher via the operation terminal 14. The dispatcher selects to approve or reject by operating the operation terminal 14. In step S11, the transmission unit 24 transmits the approval result, which is information indicating approval or rejection, to the work plan management device 12.

[0065] The approval result receiving unit 36 ​​of the work plan management device 12 sends the approval result to the operation terminal 15 via the transmitting unit 34. The work plan management device 12 then notifies the worker of the approval result. If the start of the work is approved by the dispatcher, the work begins. With this, the command support system 10 completes its operation according to the procedure shown in Figure 5.

[0066] Next, a specific example of creating a train schedule plan by selecting candidates for the train schedule plan in the train schedule plan creation unit 43 will be described. Figure 6 is the first diagram illustrating a specific example of creating a train schedule plan by selecting candidates for the train schedule plan in the train schedule plan creation unit 43 of the command support system 10 according to Embodiment 1.

[0067] Figure 6 shows an example of a graph representing train operations. In the graph shown in Figure 6, the vertical axis represents station names and the horizontal axis represents time. The graph shown in Figure 6 is displayed on the operating terminal 14. Here, A, B, C, and D are the names of trains that are in operation. In the following explanation, the trains in operation will be referred to as train A, train B, ..., etc. Object 57 represents a train leaving the depot. Object 58 represents a train entering the depot. In the example shown in Figure 6, station X is assumed to be a station with a depot. The train set used as train D leaves the depot at station X, and the train set used as train C enters the depot at station X.

[0068] Object 59 represents the portion of the work schedule that overlaps with the work intervals and time shown in the work plan, i.e., the portion where the work plan is disrupted. The graph shown in Figure 6 represents the graph when the work plan is disrupted due to delays in the schedule.

[0069] According to the planned timetable shown in Figure 6, train A, which arrived at station X, was scheduled to depart from station X before 10:00 AM as train B after turning around at station X. However, according to the actual timetable shown in Figure 6, train A has not yet arrived at station X at the current time due to delays, but has arrived at station Y. According to the predicted timetable, train A will travel from station Y towards station X from the current time onward.

[0070] According to the predicted timetable, a delay in train A will cause train B's departure from station X to be delayed until after 10:30. Meanwhile, the work plan indicates that work will be carried out between station Y and station Z from 11:00 to 12:00. The planned work will be work α, work β, and work γ.

[0071] As shown in Figure 6, the delay in the timetable disrupted the work plan, prompting the train schedule creation unit 43 to create several candidate train schedules. Here, we will describe an example in which the train schedule creation unit 43 creates two candidates and selects one of them as the train schedule by evaluating the cost of changing each candidate. Hereafter, the two candidates will be referred to as the first candidate and the second candidate.

[0072] Figure 7 is a second diagram illustrating a specific example of how the operation schedule creation unit 43 of the command support system 10 according to Embodiment 1 creates an operation schedule by selecting a candidate for the operation schedule. Figure 7 shows the timetable and work plan when the operation schedule is adjusted using the first candidate. The first candidate is a case in which the disruption shown in Figure 6 is avoided by changing the work plan without changing the timetable from the predicted timetable.

[0073] In the first candidate shown in Figure 7, the work section has been changed from Station Y to Station Z to Station X to Station Y. Also, the work time has been changed from 11:00-12:00 to 11:30-12:00. Furthermore, the work content has been changed from work α, work β, and work γ to work α and work β.

[0074] Figure 8 is a third figure illustrating a specific example of how the operation schedule creation unit 43 of the command support system 10 according to Embodiment 1 creates an operation schedule by selecting a candidate for the operation schedule. Figure 8 shows the timetable and work plan when the operation schedule is adjusted using the second candidate. The second candidate is a case in which the disruption shown in Figure 6 is avoided by changing the timetable from the predicted timetable without changing the work plan.

[0075] In the second candidate shown in Figure 8, train B, which was scheduled to operate, has been changed to a cancelled service. In the predicted timetable shown in Figure 6, the train set of train B, which arrived at station Z, was scheduled to be used as train C by turning around at station Z. In the second candidate, due to the cancellation of train B, instead of the train set of train B being used for train C, a train set released from the depot will be used for train C. Also, in the second candidate, since the train set of train A, which arrived at station X, will no longer be used for train B, the train set of train A, which arrived at station X, will be used for train D. In other words, the train set used for train D will be changed from a train set released from the depot at station X to a train set that was used for train A. Furthermore, in the second candidate, the cancellation of train B has resulted in the addition of train E. The operation adjustment proposal creation unit 43 sets the changes regarding the operation of train sets in the candidate operation adjustment proposal by determining the parts of the vehicle operation prediction information that can be changed. Furthermore, the Operation Plan Creation Department 43 determines, based on crew duty information, whether or not it is possible to change the assignment of crew members in accordance with changes in the operation of the train formation.

[0076] Figure 9 is the first diagram illustrating an example of calculating change costs by the operation plan creation unit 43 of the command support system 10 according to Embodiment 1. Figure 9 shows an example of calculating change costs for the first candidate. The changes in the first candidate are three: "change the work section from station X to station Y", "remove work γ from the work content", and "reduce the work time to 30 minutes".

[0077] Here, we assume that a numerical value for the change cost has been set for each change in a pre-prepared list. The numerical value for the change cost is set based on the rationale corresponding to the nature of the change. Figure 9 and Figure 10, described later, show the rationale for the change cost for each change as supplementary information.

[0078] The operation plan creation unit 43 determines the change cost for each change by referring to the list. In one example, the change costs shown in the list are defined by the railway operator using the command support system 10. According to the example shown in Figure 9, the change cost for "changing the work section from station X to station Y" is "10", the change cost for "removing work γ from the work content" is "0", and the change cost for "reducing the work time to 30 minutes" is "2". The operation plan creation unit 43 then sums up the change costs for each of these changes. In the example shown in Figure 9, by adding up the change cost values ​​for the three points above, the total change cost for the first candidate is determined to be "12".

[0079] Figure 10 is a second diagram illustrating an example of calculating change costs by the operation schedule creation unit 43 of the command support system 10 according to Embodiment 1. Figure 10 shows an example of calculating change costs for a second candidate. The changes in the second candidate are four points: "cancel train B," "use a different train set for train C," "use the train set of train A for train D," and "add train E."

[0080] According to the example shown in Figure 10, the change cost for "cancelling train B" is "7", the change cost for "using a different train set for train C" is "1", the change cost for "using the train set of train A for train D" is "2", and the change cost for "adding train E" is "5". In the example shown in Figure 10, by adding up the change costs for the above four points, the total change cost for the second candidate is found to be "15".

[0081] The train schedule revision creation unit 43 selects the first candidate, which has the smaller total change cost among the first and second candidates, as the train schedule revision plan. If the train schedule revision creation unit 43 has created three or more candidates, it selects the one candidate with the smallest total change cost among the three or more candidates as the train schedule revision plan.

[0082] Figure 11 shows an example of the display of a proposed operational reorganization plan on the operation terminal 14 of the command support system 10 according to Embodiment 1. Figure 11 shows an example of the display of the first candidate operational reorganization plan. Figure 11 shows a graph similar to the graph shown in Figure 7, with a pop-up displaying the changes shown in the operational reorganization plan superimposed on it. In Figure 11, objects representing the work plan before the changes are shown with dashed lines. The dispatcher can easily understand the contents of the operational reorganization plan through the display shown in Figure 11.

[0083] In the above, one candidate was selected by summing the change costs calculated based on a pre-prepared list and comparing the change costs of each candidate. The method for selecting a candidate for the operational reorganization plan is not limited to the above method. For example, the operational reorganization plan creation unit 43 may select a candidate by using a cost calculation model created by machine learning.

[0084] The train operation plan creation unit 43 may also create a train operation plan by using a model that has learned the relationship between the timetable forecast information, work status forecast information, vehicle operation forecast information, and crew duty forecast information input to the train operation plan creation unit 43 and the train operation plan information that represents the created train operation plan. The train operation plan creation unit 43 can create a train operation plan by inputting the timetable forecast information, work status forecast information, vehicle operation forecast information, and crew duty forecast information into the model. As a result, the information processing device 13 can create a train operation plan that enables smooth train operation and appropriate maintenance of railway equipment based on the relationship between the timetable forecast information, work status forecast information, vehicle operation forecast information, and crew duty forecast information and the train operation plan information. Alternatively, the train operation plan creation unit 43 may also create a train operation plan by inputting the timetable forecast information and work status forecast information into a model that has learned the relationship between the timetable forecast information and work status forecast information and the train operation plan information.

[0085] In the above, the prediction unit 42 is configured to perform an operation simulation that predicts the future train schedule, future work status, future vehicle operation status, and future crew work status based on the schedule information, work plan information, operation performance information, vehicle operation information, and crew work status information. The operation simulation in Embodiment 1 is not limited to being performed based on the schedule information, work plan information, operation performance information, vehicle operation information, and crew work status information. The prediction unit 42 only needs to perform an operation simulation based on at least the schedule information, work plan information, and operation performance information. That is, the prediction unit 42 may also predict the future train schedule and future work status based on the schedule information, work plan information, and operation performance information. Alternatively, the prediction unit 42 may also predict the future train schedule and future work status based on the schedule information, work plan information, operation performance information, and information on weather or disasters.

[0086] Furthermore, in the above, the train schedule plan creation unit 43 is configured to create a train schedule plan based on timetable forecast information, work status forecast information, vehicle operation forecast information, and crew duty forecast information. In Embodiment 1, the train schedule plan is not limited to being created based on timetable forecast information, work status forecast information, vehicle operation forecast information, and crew duty forecast information. The train schedule plan only needs to be created based on at least timetable forecast information and work status forecast information.

[0087] Next, the hardware that implements the operation management device 11, the work plan management device 12, and the information processing device 13 according to Embodiment 1 will be described. Each of the operation management device 11, the work plan management device 12, and the information processing device 13 is implemented using a processing circuit. A processing circuit is a circuit in which a processor executes software. An example of a processing circuit is the control circuit shown in Figure 12.

[0088] Figure 12 shows an example configuration of a control circuit 80 according to Embodiment 1. The control circuit 80 comprises an input unit 81, a processor 82, a memory 83, and an output unit 84. The input unit 81 is an interface circuit that receives data from outside the control circuit 80 and provides it to the processor 82. The output unit 84 is an interface circuit that sends data from the processor 82 or the memory 83 to the outside of the control circuit 80.

[0089] The functions of the information management unit 22 and approval processing unit 26, which are processing units of the operation management device 11 shown in Figure 1, the functions of the work plan management unit 32, which is processing unit of the work plan management device 12 shown in Figure 1, and the functions of the prediction unit 42 and operation plan creation unit 43, which are processing units of the information processing device 13 shown in Figure 1, are realized by software, firmware, or a combination of software and firmware. The software or firmware is written as a program and stored in memory 83. The processing circuit realizes these processing units by having the processor 82 read and execute the program stored in memory 83. In other words, the processing circuit includes memory 83 for storing programs that will result in the execution of processing by the operation management device 11, the work plan management device 12, or the information processing device 13. The program stored in memory 83 is a program that causes the computer to execute the procedures and methods of processing by the operation management device 11, the work plan management device 12, or the information processing device 13.

[0090] The information acquisition unit 21 and approval request receiving unit 25 of the operation management device 11, the information acquisition unit 31, approval request receiving unit 35, and approval result receiving unit 36 ​​of the work plan management device 12, and the information acquisition unit 41 of the information processing device 13 are realized by using the input unit 81. The transmission unit 24 of the operation management device 11, the transmission unit 34 of the work plan management device 12, and the transmission unit 44 of the information processing device 13 are realized by using the output unit 84. The storage unit 23 of the operation management device 11 and the storage unit 33 of the work plan management device 12 are realized by using the memory 83. The memory 83 is also used as temporary memory when the processor 82 performs various processes.

[0091] The processor 82 is a CPU (Central Processing Unit). The processor 82 may also be a central processing unit, processing unit, arithmetic unit, microprocessor, microcomputer, processor, or DSP (Digital Signal Processor). The memory 83 includes, for example, non-volatile or volatile semiconductor memory such as RAM (Random Access Memory), ROM (Read Only Memory), flash memory, EPROM (Erasable Programmable Read Only Memory), EEPROM (Registered Trademark) (Electrically Erasable Programmable Read Only Memory), magnetic disks, flexible disks, optical disks, compact disks, minidiscs, or DVDs (Digital Versatile Discs).

[0092] The processing circuit may be a dedicated circuit. A dedicated circuit may be a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a circuit combining these.

[0093] Each component of the command support system 10 does not need to be physically configured as shown in the diagram. The specific forms of distribution and integration of each component are not limited to those shown. Each component may be configured functionally or physically distributed in any unit, or it may be configured as an integrated unit.

[0094] The program according to Embodiment 1 may be provided on a recording medium such as a CD (Compact Disc)-ROM or DVD-ROM. The program according to Embodiment 1 may be provided by being stored on a computer connected to a network such as the Internet and downloaded via the Internet or other network. The program according to Embodiment 1 may be provided or distributed via a network such as the Internet.

[0095] According to Embodiment 1, the information processing device 13 includes a prediction unit 42 that predicts the future train schedule and the future work status related to the maintenance of railway equipment based on timetable information, work plan information, and operational performance information, and an operation adjustment plan creation unit 43 that creates an operation adjustment plan including changes to the work plan based on timetable prediction information showing the predicted timetable and work status prediction information showing the predicted work status. By having the operation adjustment plan creation unit 43 create an operation adjustment plan including changes to the work plan, the information processing device 13 can create an operation adjustment plan including appropriate changes to the work plan without relying on judgment by personnel such as dispatchers or workers. As a result, the information processing device 13 has the effect of being able to support the appropriate changes to the work plan related to the maintenance of railway equipment.

[0096] The operation reorganization plan creation unit 43 creates multiple candidate operation reorganization plans, evaluates at least one of the load associated with changes to the operation plan and the load associated with changes to the work plan for each of the candidates, and selects a candidate to be adopted as the operation reorganization plan based on the evaluation results for each of the candidates. As a result, the information processing device 13 can create an operation reorganization plan that takes into account the load associated with changes to the operation plan and the load associated with changes to the work plan.

[0097] The prediction unit 42 predicts the future train schedule and future operational status based on weather or disaster information. This enables the information processing device 13 to propose operational adjustment plans that take into account the impact of weather, disaster prevention, or accident prevention.

[0098] The train schedule planning unit 43 creates a train schedule plan by inputting the timetable forecast information and the work status forecast information into a model that has learned the relationship between the timetable forecast information and the work status forecast information and the train schedule information that shows the created train schedule plan. As a result, the information processing device 13 can create a train schedule plan that enables smooth train operation and appropriate maintenance of railway equipment.

[0099] The prediction unit 42 predicts the future train timetable, future work status, future vehicle operation status, and future crew operation status based on vehicle operation information showing the operation plan of the vehicles constituting the train, and crew operation information showing the crew's work schedule. The operation adjustment plan creation unit 43 then creates an operation adjustment plan based on the predicted vehicle operation forecast information showing the predicted vehicle operation status and the predicted crew operation forecast information showing the predicted crew operation status. As a result, the information processing device 13 can take into account the predicted vehicle operation status and the predicted crew operation status and provide support for appropriately changing the work plan related to the maintenance of railway equipment.

[0100] The train schedule revision creation unit 43 creates multiple candidate train schedule revisions, evaluates the load associated with changes to the operation plan and the load associated with changes to the work plan, operational plan, or duty plan for each of the candidates, and selects a candidate for the train schedule revision based on the evaluation results for each of the candidates. As a result, the information processing device 13 can create a train schedule revision that takes into account the load associated with changes to the operation plan and the load associated with changes to the work plan.

[0101] The prediction unit 42 predicts the future train schedule, future work status, future vehicle operation status, and future crew status based on timetable information, work plan information, operational performance information, vehicle operation information, crew duty information, and weather or disaster information. This enables the information processing device 13 to propose operational adjustment plans that take into account the impact of weather, disaster prevention, or accident prevention.

[0102] The train operation plan creation unit 43 creates a train operation plan by inputting the timetable forecast information, work status forecast information, vehicle operation forecast information, and crew duty forecast information into a model that has learned the relationship between the timetable forecast information, work status forecast information, vehicle operation forecast information, and crew duty forecast information and the train operation plan information that represents the created train operation plan. As a result, the information processing device 13 can create a train operation plan that enables smooth train operation and appropriate maintenance of railway equipment.

[0103] Furthermore, according to Embodiment 1, the command support system 10 assists in command operations for train operations. The command support system 10 includes an operation management device 11 that manages timetable information showing train operation plans and operation performance information showing actual train operation results, a work plan management device 12 that manages work plan information showing work plans related to the maintenance of railway equipment, a prediction unit 42 that predicts future train timetables and future work status related to the maintenance of railway equipment based on timetable information, work plan information, and operation performance information, and an information processing device 13 that has a timetable prediction information showing the predicted timetable and work status prediction information showing the predicted work status that creates an operation adjustment plan including changes to the work plan. As a result, the command support system 10 can provide support for appropriately changing work plans related to the maintenance of railway equipment. Moreover, even if the work plan is changed on the same day, it can be immediately reflected in the command support system 10, and approval can be requested and immediately obtained in the command support system 10. As a result, the command support system 10 can reduce the impact of disruptions to the timetable.

[0104] The configurations shown in the embodiments described above are examples of the content of this disclosure. The configurations of the embodiments can be combined with other known technologies. Some parts of the configurations of the embodiments can be omitted or modified without departing from the spirit of this disclosure.
