Description

  The present invention relates to a diamond management method, a program, and a technology of a diamond management apparatus.

  In the train operation management system, when the train is unable to travel according to the planned time due to trouble, the train diagram (hereinafter referred to as “diagram”) may be changed to minimize the delay of the train. Is called. The operation to return the train operation to the normal state by this change is called operation arrangement.

  In recent years, there has been a growing need for quick recovery from disrupted driving conditions in order to increase the complexity of driving arrangements due to the diversification of vehicle types and congestion, and to improve customer service. Is required.

  One of such computer systems that support operation arrangement work is a diamond prediction function. The diamond prediction function is a function that predicts the future train operation status from train travel performance information up to the current time (hereinafter referred to as performance information). Specifically, the arrival and departure times at each station in the future are predicted from the past performance information based on the forecast conditions that are constraints when forecasting the schedule, such as the shortest time that the train must travel between stations calculate.

  Patent Document 1 describes a driving arrangement support system that automatically generates an appropriate driving arrangement plan while combining a plurality of proposed functions based on a local proposal function selected by a user and an evaluation index.

JP 2008-49853 A

  However, in the diamond prediction function, since the prediction conditions are uniquely determined in advance, it is difficult to predict a flexible diamond according to the actual operation status. The user needs to redo the setting for changing the diagram if the expected result of the schedule is not obtained by looking at the expected result of the diagram. That is, since the prediction conditions in the conventional diamond prediction function are determined in advance, it is difficult to predict the schedule according to the actual train operation status (result information) and the user's intention. Therefore, it is necessary for the user to make further changes to the prediction diagram so that a more appropriate prediction result can be obtained based on the prediction result, and it takes time and effort to recover the operation status.

  Further, in the technique described in Patent Document 1, since the priority between the proposed functions is set in advance, it is difficult to change the prediction condition corresponding to the actual operation status (result information).

  The present invention has been made in view of such a background, and an object of the present invention is to perform dynamic diagram prediction.

In order to solve the above-described problem, the present invention provides a prediction condition in which a user inputs a check into a check box indicating invalidity of constraint conditions that are all valid in the initial conditions via a prediction condition setting screen displayed by a user instruction. Is set, a diamond prediction process is performed in accordance with the set prediction condition. Here, on the setting screen, a setting screen for a route for setting a constraint condition applied to the entire route and a setting screen for a station for setting a constraint condition at the station are displayed.

  According to the present invention, dynamic diamond prediction can be performed.

《Various tables》
Next, with reference to FIGS. 2 to 8, each table used in the present embodiment will be described.

(Planning diagram table)
FIG. 2 is a diagram illustrating a configuration example of a plan diagram table according to the present embodiment.
The plan diagram table 301 is a table in which schedules according to a timetable are stored, and as shown in FIG. 2, station departure and arrival times and number lines to arrive and depart are stored for each train. The number line is a number line on which the train described on the left side arrives and departs, and the blank indicates that it is a single line or a station that has one up / down number of arrival / departure number lines. For example, in the example of FIG. 2, at station C, the L train arrives and departs on line 3, and the N train departs and arrives on line 2.

(Results diamond table)
FIG. 3 is a diagram illustrating a configuration example of a record diagram table according to the present embodiment. FIG. 3 shows an actual diagram table at 7:11 as an example.
The record diagram table 307 is a table that stores record information acquired by the diagram management apparatus 2 from the operation monitoring apparatus 4 installed at each station. The configuration of the record diagram table 307 is the same as that of the plan diagram table 301 in FIG. 2 and thus will not be described. However, in the example shown in FIG. 3, since the current time is 7:11, only data before that is collected. Indicates a situation that has not been done. Further, it can be seen that there is a delay in each train as compared with the plan diagram table 301 in FIG.

(Expected diamond table)
FIG. 4 is a diagram illustrating a configuration example of the prediction diagram table according to the present embodiment.
The expected diagram table 308 is a table that stores the expected diagrams based on the actual diagram table 307 and the planned diagram table 301. The configuration of the forecast diagram table 308 is the same as that of the plan diagram table 301 in FIG. 2 and the record diagram table 307 in FIG. 3, and thus will not be described. In FIG. This is the same as the actual diagram table 307 of FIG. In Fig. 4, the N train originally arrived at the 3rd line because the 2nd train (see Fig. 2), where the N train should have arrived and departed, was used for other trains. Thus, it can be seen that there is a contradiction in the competition between the numbered lines competing with the arrival and departure number lines of the L train.

(Expected condition management table)
FIG. 5 is a diagram showing a configuration example of the prediction condition management table according to the present embodiment.
The prediction condition management table 302 stores the prediction conditions set on the prediction condition setting screen described later in FIGS. 9 and 10. Here, the predicted condition is a condition in which individual constraint conditions are set to be valid / invalid.
In FIG. 5, first, the setting conditions of the prediction conditions for each route (α route, β route,...) Are stored, and then for each station (A station, B station, C station, D station,...). Stores the setting condition of the expected condition in. Further, in the example of FIG. 5, the setting condition of the prediction condition is shown depending on whether each constraint condition is invalid (O) or not (X).
Here, the line conflict is a situation where a plurality of trains enter the same line at the same time. The line conflict determination is invalid when the diagram management device 2 makes a schedule prediction. Do not check. For example, when the passenger is waiting at the home, it is not preferable to change the number line. Therefore, in such a case, the user sets the line conflict determination to invalid.
In addition, A station, B station, C station, and D station are stations on the α route, and stations on the β route exist separately.

  The departure order is a condition that restricts the departure order of the trains at the station. The departure order contradiction determination invalidity is made possible by making the departure order of trains free when the diagram management device 2 makes a prediction of a diagram. is there. In addition, although not shown in FIG. 5, the stop time is a condition that restricts the time that the train must stop at the station, and the stop time judgment invalidity is that of the diagram management device 2 diagram. When making predictions, do not check the stop time.

  The time zone indicates a time zone in which the corresponding forecast condition is applied. In the example of FIG. 5, the entire route (α route, β route,...) Is blank because no time zone is specified.

(Expected conflict management table)
FIG. 6 is a diagram illustrating a configuration example of a predicted contradiction management table according to the present embodiment.
The prediction contradiction management table 303 is a table that stores information on the contradiction generated as a result of the diamond prediction. The predicted contradiction management table 303 includes information on the station where the contradiction occurred, the content of the contradiction, and the train name where the contradiction occurred. As shown in FIG. 4, when a contradiction occurs between the L train and the N train at the C station, as shown in FIG. 6, the station is “C station”, the content is “number line conflict”, “L train, N train” is stored in “train name”. Note that the blanks in FIG. 6 may be filled when a plurality of contradictions occur, but in the example of FIG. 6, only one contradiction has occurred, indicating that it is blank. ing.

(Proposed pattern table)
FIG. 7 is a diagram illustrating a configuration example of the proposal pattern table according to the present embodiment.
The proposal pattern table 305 is a template of a coping method (proposed content) for coping with the contradiction that has occurred. As illustrated in FIG. 7, the proposed pattern table 305 stores inconsistency contents, countermeasure contents for dealing with the contradictory contents, and conditions for selecting the countermeasure contents in association with each other in advance. .
In the example shown in FIG. 7, it is shown that when there is a number line conflict, when all the number lines are filled, it is dealt with by changing the departure order, and when there is a vacant number line, it is dealt with by changing the number line. . Similarly, when a departure order contradiction occurs, if there is a vacant number line, it is indicated that the number line is changed.

(Proposal information management table)
FIG. 8 is a diagram illustrating a configuration example of a proposal information management table according to the present embodiment.
The proposal information management table 304 is a table that stores information on a coping method (suggestion) selected with reference to the proposal pattern table 305 of FIG. 7 when a contradiction occurs as a result of calculating an expected diagram.
As shown in FIG. 8, the proposal information management table 304 has proposal contents, target trains, and target stations. In the example of FIG. 8, as shown in FIG. 4, when a contradiction occurs between the L train and the N train at station C as shown in FIG. 4, it is shown that the departure order change is selected as a countermeasure. Note that the blank in FIG. 8 may be filled when a plurality of proposals are selected, but in the example of FIG. 8, only one proposal is selected, so it is blank. Is shown.

《Setting / Proposal Screen》
Next, an example of a setting / proposing screen according to the present embodiment will be described with reference to FIGS.

(Overall forecast condition execution screen)
FIG. 9 is a diagram illustrating an example of the overall prediction condition setting screen according to the present embodiment.
The overall prediction condition setting screen 901 is a screen for setting prediction conditions for the entire route.
In the screen example shown in FIG. 9, regarding the α route, “number line conflict determination invalid”, “stop time determination invalid”,... . Here, only the departure order contradiction determination invalid is selected, but a plurality of prediction conditions may be selected, or not all of the prediction conditions may be selected. If not all prediction conditions are selected, the diamond is predicted with all the constraints valid.
When the confirmation button 903 is selected and input, the contents set on the overall prediction condition setting screen 901 are stored in the prediction condition management table 302.
The overall prediction condition setting screen 901 in FIG. 9 can be displayed when the user likes, and the prediction conditions for the entire route can be set when the user likes. For example, when trouble occurs, the user can set the prediction condition by confirming the operation status and the state of passengers at the home.

(Local prediction condition setting screen)
FIG. 10 is a diagram illustrating an example of a local prediction condition setting screen according to the present embodiment.
The local prediction condition setting screen 1001 is a screen for setting prediction conditions at each station.
In the prediction condition selection area 1002 in FIG. 10, the prediction conditions from the A station to the D station can be selected and input by the check box 1003. Each prediction condition is the same as in FIG.
In the time zone selection area 1004, a time zone in which the selected prediction condition is valid is set by inputting a start time and an end time.
When the confirmation button 1005 is selected and input, the contents set on the local prediction condition setting screen 1001 are stored in the prediction condition management table 302.
The local prediction condition setting screen 1001 in FIG. 10 can be displayed when the user likes, and the prediction condition at each station can be set when the user likes.

  For example, as described above, when the passenger is waiting at the home, the user sets the number conflict determination invalidity on the local prediction condition setting screen 1001. According to the present embodiment, it is possible to set a dynamic prediction condition according to the actual operation situation and the situation at home as described above.

(Contradiction setting screen)
FIG. 11 is a diagram illustrating an example of a conflict handling setting screen according to the present embodiment.
In the contradiction handling setting screen 1101, a handling method for a contradiction generated as a result of the diamond prediction is displayed in the contradiction handling proposal area 1102. The coping proposal selection process will be described later.
When the user selects and inputs the confirmation button 1104 displayed in the proposal confirmation area 1103, the prediction function control unit re-predicts a diagram using the coping method proposed for the contradiction coping proposal. When the user selects the discard button 1105, the proposed coping method is discarded and the current expected diagram is retained.

  In this way, by causing the user to select and display the countermeasure proposal, it is possible to deal with inconsistencies caused by setting the prediction condition, that is, by removing the restriction at the time of the diamond prediction according to the situation.

《Diagram example》
Next, an example of a diagram in each state will be described with reference to FIGS.

FIG. 12 is a diagram illustrating an example of a plan diagram according to the present embodiment.
The example of FIG. 12 shows a diagram based on the plan diagram table 301 of FIG. As shown in FIG. 12, if the L train (solid line) and the N train (broken line) are operating according to the timetable, the L train arrives and departs on line 3 and the N train arrives and departs on line 2 at station C. It can be seen that the N train departs first.

FIG. 13 and FIG. 14 are diagrams showing examples of an expected diagram according to the present embodiment.
FIG. 13 shows a diagram of the expected diagram table 308 of FIG. As shown in FIG. 13, as a result of the delay in the L train and the N train, the N train is changed to the third track due to the fact that the second line of the C station that should be used by the N train is used for other trains. Thus, a contradiction in the competition of the numbered lines occurs at reference numeral 1301.

  Therefore, the diagram management apparatus 2 presents a proposal to “change the departure order of the L train and the N train” as shown in FIG. 11, and the user selects and inputs the confirmation button 1104 shown in FIG. FIG. 14 shows that the contradiction of the diamond is resolved as a result of re-predicting the diamond according to the proposal. At this time, the diamond prediction unit 213 performs the diamond re-prediction in a state where the train has set the departure order contradiction determination invalidity at the C station.

  FIG. 14 shows an example of a re-predicted prediction diagram. Here, although the departure order is free, the restriction for the stop time is not removed, so the diamond prediction unit 213 greatly delays the N train diagram. The departure order is adjusted accordingly.

"flowchart"
FIG. 15 is a flowchart showing a procedure in the diagram prediction method according to the present embodiment.
First, when the user inputs a prediction condition setting command via the input unit 230, the prediction condition management unit 211 displays an overall prediction condition setting screen 901 shown in FIG. 9 or FIG. A screen 1001 is displayed on the display unit 240. Then, when the user sets the prediction condition displayed on the overall prediction condition setting screen 901 or the local prediction condition setting screen 1001 via the input unit 230 (S101), the prediction condition management unit 211 sets the set prediction. The conditions are stored in the expected condition management table 302. Note that the setting of the prediction condition is not limited to this timing, and can be performed when the user likes.

And the performance information management part 212 acquires performance information from the performance information provision part 401 of the operation monitoring apparatus 4 (S102), and stores the acquired performance information in the performance diagram table 307.
Next, the diagram predicting unit 213 performs a diagram prediction process using the plan diagram table 301 and the actual diagram table 307 in accordance with the forecast condition set in step S101 (S103). For the diamond prediction, for example, the diamond prediction unit 213 calculates a diamond delay time from the actual diamond table 307 and the planned diamond table 301 at each point (the station in this case) for which the actual information has been acquired, This is performed by adding the calculated delay time to the time of the plan diagram table 301. At this time, the delay time to be added may be reduced as the point (station) near the terminal station, that is, away from the current time in the future direction. This is a procedure performed to gradually recover the diamond delay.
The predicted diagram is stored in the predicted diagram table 308 by the diagram prediction unit 213.

Next, the contradiction detection unit 214 refers to the expected diagram table 308 to determine whether or not a contradiction has occurred (S104). The determination is made by the contradiction detection unit 214 searching for, for example, whether there is a train using the same line at the same time in the prediction diagram table 308.
If no contradiction has occurred as a result of step S104 (S104 → No), the processing unit 210 returns to the processing of step S102, and the diagram prediction unit 213 displays a prediction diagram based on the current prediction diagram table 308 on the display unit 240. It is displayed (S111).
If a contradiction has occurred as a result of step S104 (S104 → Yes), the contradiction detection unit 214 stores the station, train, and contradiction content in which the contradiction occurs in the predicted contradiction management table 303 (S105). Contradiction content is stored in the database 3 in advance as information (not shown) in which the content of the expected diagram table 308 and the content of the contradiction are associated with each other, such as “number conflict if the same line is used at the same time”. It is realized with.

Next, the proposal management unit 215 refers to the predicted contradiction management table 303, the predicted diagram table 308, and the proposed pattern table 305 to select a conflict handling proposal for the contradiction detected in step S102 (S106). . For example, the proposal management unit 215 searches for the contradiction content of the proposal pattern table 305 using information described in the content of the expected contradiction management table 303 as a key. Then, the proposal management unit 215 reads the information described in the condition column corresponding to the corresponding contradiction content in the proposal pattern table 305 and compares the read information with the expected diagram table 308. Next, the proposal management unit 215 reads a countermeasure content that matches the condition from the proposal pattern table 305 and selects a contradiction countermeasure proposal. If no corresponding countermeasure content is detected at this time, the processing unit 210 causes the display unit 240 to display that the countermeasure content is not found, and causes the display unit 240 to display the current diagram. In this case, the user manually changes the diamond.
Then, the proposal storage unit 216 stores the information on the contradiction handling proposal selected in step S106 in the proposal information management table 304 (S107).

And the process part 210 determines whether the process of step S101 to step S105 was performed about all the points (stations) (S108).
As a result of step S108, when all the points have not been processed (S108 → No), the processing unit 210 returns to the process of step S104.
If all points have been processed as a result of step S108 (S108 → Yes), the content stored in the proposal information management table 304 by the processing unit 210 is displayed as shown in FIG. Is displayed on the display unit 240 (S109).
Then, the processing unit 210 determines whether or not the user has approved the handling proposal by determining whether or not the confirmation button 1104 illustrated in FIG. 11 has been selected and input (S110).

As a result of step S110, when the approval by the user is not performed (S110 → No), that is, when the discard button 1105 shown in FIG. 11 is selected and input, the diagram prediction unit 213 holds the current diagram diagram 308. Then, an expected diagram based on the expected diagram table 308 is displayed on the display unit 240 (S111).
As a result of step S110, when the approval is performed by the user (S110 → Yes), that is, when the confirmation button 1104 shown in FIG. 11 is selected and input, the diagram predicting unit 213 performs a diagram based on the approved handling proposal. When the prediction diagram table 308 is updated, a prediction diagram based on the updated prediction diagram table 308 is displayed on the display unit 240 (S113).
