First Embodiment
FIG. 1 is a block diagram showing a configuration example of the operation management support device of the first embodiment. As shown in FIG. 1, the operation management support apparatus 100 is an apparatus provided to support the operation management system 150. In the present embodiment, a system in which the operation management support apparatus 100 and the operation management system 150 that manages the operation of the train are combined is referred to as an operation control system 1.

It may be realized by reading and expanding in a storage area by the CPU.

  The operation management support apparatus 100 according to the present embodiment includes the above-described configuration, thereby specifying the configuration (for example, device) to be corrected included in the operation management system 150 and correcting the configuration. We will calculate the effects and costs. Next, an example of the configuration to be corrected included in the operation management system 150 will be described.

  FIG. 2 is a diagram showing an example of a configuration included in the operation management system 150 of the present embodiment. As shown in FIG. 2, the operation management system 150 includes a vehicle 201, a vehicle operation planning device 202, a station facility 203, an operation adjustment device 204, an operation management device 205, a diagram creation device 206, and an operation curve. A creation device 207 and a driving support device 208 are provided.

  The vehicle 201 is a vehicle that travels in the route managed by the operation management system 150 as a train.

  The vehicle operation planning device 202 is a device that creates and changes a vehicle operation plan. The vehicle operation plan is a plan that determines which trains the plurality of vehicles 201 provided in the operation management system 150 are to travel. As the correction of the vehicle operation planning device 202 in the present embodiment, in addition to changing the algorithm of the vehicle operation plan, the number of vehicles 201 and the operation method of the vehicles 201 may be changed.

  The station facility 203 is a device provided at each station, and includes at least a passenger guidance device 211 and a departure guidance device 212. The passenger guidance device 211 outputs information for guiding a passenger at each station. The departure guidance device 212 outputs information for guiding the arrival and departure of a train at each station. In addition to changing the information output from at least one or more of the passenger guidance device 211 and the departure guidance device 212 as correction of the station facility 203 in the present embodiment, installation of a home door, or a station It also includes changes in the number of station members that exist.

  The operation adjustment device 204 is a device that adjusts the operation of the vehicle 201. For example, when a delay of a train occurs from a predetermined timetable, the operation adjustment device 204 adjusts the traveling time between stations of the vehicle 201 and the like. As a correction of the operation adjustment device 204, for example, a change of an adjustment algorithm of the traveling time of the vehicle 201 in the case where a delay of the vehicle 201 occurs or a delay is predicted can be considered.

  The operation management device 205 is a device that manages the operation of the vehicle 201, and performs route control of the vehicle 201, for example. As a modification of the operation management device 205, for example, a change of an operation management algorithm including route control can be considered.

  The diagram creation device 206 creates an operation diagram for causing the vehicle 201 to travel. As a modification of the diagram creating device 206, for example, a change of an algorithm for creating an operation diagram when a delay occurs, etc. can be considered in addition to a change of a predetermined diagram.

  The driving support device 208 performs control for supporting the traveling of the vehicle 201. As a modification of the driving support device 208, for example, a change of an algorithm for supporting the operation of the vehicle when a delay or the like occurs can be considered.

  The example of the correction target in the operation management system 150 of the present embodiment has been described. However, in the present embodiment, not only the above-described configuration is to be corrected, but other configurations may be corrected. For example, a signal system (interlocking device, branching device) or a driving education training device may be a correction target.

  The correction of the configuration in the present embodiment is not limited to the change of the above-described algorithm or the like, and the configuration may be replaced, the configuration may be added, or the like.

  Returning to FIG. 1, the input unit 111 inputs the operation data 180 from the operation management system 150. The operation data of the present embodiment includes at least performance diamond data 181 and predetermined diamond data 182.

  The track record data is the track data indicating the track record of operation of the train managed by the service management system 150 according to the route. The operation record is, for example, a history including arrival time at each station when actually traveling along the route and departure time.

  The predetermined diagram data is diagram data indicating the operation status when the train whose operation management system 150 is targeted for operation management operates on time according to the operation plan. The operation status includes, for example, arrival time at each station and departure time.

  In addition, although the operation data 180 is data directly related to the travel of the train, as indicated by the above-mentioned actuals diagram data 181 and the predetermined diagram data 182, it is possible to include data indirectly related to the travel of the train good.

  For example, as the operation data 180, weather data, temperature data, text data written by a passenger when a delay occurs, or image data photographed by a passenger (a crowded station or train posted to an information service on the Internet) Indirectly related data such as data indicating the condition may be included.

  The index extraction unit 112 includes an analysis unit 118, and extracts an index based on the difference between the arrival time or the departure time indicated by the actual timetable data and the predetermined timetable data input-processed by the input unit 111.

  The index in the present embodiment is a parameter managed by the operation management system 150 currently operated and indicating the operation status of the train, and is a parameter used to identify the task. In the present embodiment, an example in which a delay time of stop time of a station or a delay time of inter-station travel time is extracted as an index will be described, but other parameters may be extracted (note that a delay time of stop time). Means the time when the stop time is longer than the time set for each station, and the delay time for the inter-station travel time means that the inter-station travel time is longer than the time set for each station Mean that time).

  The analysis unit 118 performs analysis processing based on the predetermined diagram data and the performance diagram data. The analysis unit 118 according to the present embodiment determines the difference between the arrival time or the departure time indicated by the performance diamond data and the predetermined diamond data, the delay time of the stopping time calculated at each station, or the inter-station calculated for each station Calculate the delay time of the running time, and perform aggregation, visualization, etc.

  Specifically, the analysis unit 118 counts, for each station, the difference between the arrival time included in the predetermined diagram data and the arrival time included in the performance diagram data within a predetermined period.

  The predetermined period may be any period, for example, a predetermined period of morning and evening on a weekday with a high possibility of delay, for example, one month, two weeks for each of spring, summer and winter, or one month. It is possible to do.

  The index extraction unit 112 may extract an index in consideration of indirectly related data as operation data. For example, when the analysis unit 118 is performing analysis processing, if there is a time zone in which the station stop time is particularly long from the actual diamond data and the predetermined diamond data, text data written by the passenger in the time zone or It is determined based on image data captured by a passenger (e.g., a station posted to an information service on the Internet and data indicating the degree of congestion of a train, etc.) whether or not it is a normal operation status. Then, when it is determined that the operating condition is not a normal operation condition, the analysis unit 118 excludes the time zone from the aggregation of the station delay time for each time zone, such as the average and the variance.

  The index database 101 is a database that holds information for extracting an index. For example, the index database 101 extracts stations having a long delay time between stations, stations having a short delay time between stations, a station having a long delay time for stopping time, and a station having a short delay time for stopping time. Store the reference value for The index database 101 of the present embodiment is an example of storing a reference value of delay time of inter-station stop time common to stations and a reference value of delay time of travel time common to stations. However, the present invention is not limited to the method of storing the common reference value, and the reference value may be stored for each station or each station.

  Furthermore, the index database 101 of the present embodiment does not store the reference value for every station, but, for example, according to the characteristics of the line area managed by the operation management system 150, a delay such as a station having a plurality of lines. Reference values may be stored only at stations that may be generated.

  Then, the index extraction unit 112 extracts an index based on the analysis result by the analysis unit 118. The index extraction unit 112 of the present embodiment is an analysis result by the analysis unit 118, among the delay time of the stop time calculated at each station and the delay time of the inter-station travel time calculated for each station, the index database The inter-station travel time delay time is longer than the standard value stored in 101. Between inter-station travel time delay time is short between stations. Stop time delay time is longer. Station stop time delay time. Extract the short station with the delay time.

  FIG. 3 is a diagram showing an average delay time of inter-station travel time, which is an analysis result by the analysis unit 118 of the present embodiment. In FIG. 3, the travel from the station A to the station B is indicated as inter-station AB. Other notations are the same. As shown in FIG. 3, the average delay time differs depending on the station. The example shown in FIG. 3 indicates that the inter-station travel time is delayed by about 40 seconds on average in the inter-station DE. In other words, inter-station DE is between stations that are prone to delay.

  Then, the index extraction unit 112 extracts that the average delay time is higher than the reference value and “the inter-station travel time is long” in the inter-station DE, as an index for extracting the task in the operation management system 150.

  As described above, the index extraction unit 112 according to the present embodiment extracts an index indicating which station and which train are delayed. Although the format of the index may be any format, it is extracted, for example, in a format such as "delay in departure time of station A" or "delay in inter-station travel time in inter-station AB".

  Returning to FIG. 1, the task extraction unit 113 extracts a task in the operation management system 150 based on the extracted index. The task extraction unit 113 of the present embodiment extracts a task that is associated with the index in the task database 102. The issue indicates the situation that needs to be solved in the operation management system. In addition, as long as the index is extracted based on the difference between the actual timetable data and the predetermined timetable data, it is possible to consider that the task corresponding to the index is also extracted based on the difference between the actual timetable data and the predetermined timetable data.

  The task extracted by the task extraction unit 113 is a task for solving the problem occurring in the operation management system 150, and, for example, “appropriateization of a predetermined traveling time between stations AB”, “actuality of station A Stop time optimization etc. can be considered.

  For example, the task extraction unit 113 optimizes the predetermined travel time associated with the “delay in inter-station travel time” when “delay in inter-station travel time” is extracted as an index. “Renewal of predetermined diagram data” or “approval of actual travel time (update of driving support control method by driving support device)” is extracted as a task.

  In the present embodiment, the number of tasks to be extracted may be determined in advance. For example, when extracting the “approval of predetermined traveling time (updating of predetermined diamond data)”, the task extraction unit 113 “optimizes the predetermined traveling time among the upper three stations between stations having a large delay (predetermined It is conceivable to extract the update of diamond data).

  The task database 102 stores the correspondence between the index and the task. FIG. 4 is a view exemplifying the correspondence relationship stored in the task database 102. As shown in FIG. As shown in FIG. 4, the task database 102 stores the index and the task in association with each other. Further, in the task database 102 of the present embodiment, when a plurality of tasks are associated with one index, which task should be preferentially extracted may be set as the priority.

  The identifying unit 114 identifies the configuration to be corrected in the operation management system 150 based on the extracted task. The identifying unit 114 of the present embodiment refers to the configuration database 103 and extracts the configuration corresponding to the task.

  The configuration database 103 stores the correspondence between the task and the configuration. FIG. 5 is a diagram exemplifying the correspondence relationship stored in the configuration database 103. As shown in FIG. As shown in FIG. 5, the configuration database 103 is configured to be a subject that may occur in the operation management system 150 and to be corrected in order to operate the train according to the predetermined diagram data when the task occurs. (Device) is stored in association with each other. Further, in the configuration database 103 according to the present embodiment, when a plurality of devices are associated with one task, which configuration is to be preferentially identified may be set as a priority. . The configuration is a configuration (apparatus) provided in the operation management system 150.

  For example, when “the optimization of the predetermined travel time (update of predetermined diamond data)” between the stations as the task is extracted, “the identification unit 114” “the optimization of the predetermined travel time (update of the predetermined diamond data)” The “diagram creation device” associated with the above is specified as the configuration to be corrected. As a result, the predetermined diagram data is updated by the “diagram creation device” for “approval of predetermined traveling time (update of predetermined diagram data)” between certain stations.

  In other words, the identification unit 114 operates the train according to the predetermined diagram data based on the difference between the actual result diamond data and the predetermined diamond data, which is the source of the task, and the configuration stored in the configuration database 103. The configuration provided in the operation management system 150 to be corrected is identified.

  The evaluation unit 115 executes simulation of effect calculation and cost calculation in the entire operation management system 150 when the configuration specified by the specifying unit 114 is corrected.

  The value calculation unit 116 calculates an effect and a cost when the specified configuration is corrected based on the simulation result by the evaluation unit 115. Then, the value calculation unit 116 determines whether the calculated effect and cost satisfy the condition defined by the commander of the operation management system 150. If it is determined that the condition is satisfied, the configuration to be corrected and the correction content for the configuration are output to the output unit 117. The correction content is assumed to be determined based on the simulation result by the evaluation unit 115.

  The effect may be calculated, for example, as an amount obtained by multiplying the unit time per unit time by the delay time to be eliminated. In the present embodiment, an example is described in which the effects and costs in the case of correcting the specified configuration are calculated as values, but the effects and costs are not limited to values for calculating only.

  Specifically, for example, the value calculation unit 116 holds in advance correspondence relationship data that the customer value per second of the delay is y yen, and for example, for the n trains, the inter-station DE 40 If it is expected that the second delay will be resolved, it is regarded as the value of the railway operator of y * n yen. Such calculation of value can proceed with the correction of the configuration quantitatively and effectively.

  Further, in the storage unit (not shown), the specified configuration may be stored in association with the effect when the configuration is corrected. In this case, from the association stored in the storage unit, the effect in the case of correcting the configuration can be derived.

  FIG. 6 is a diagram exemplifying the correspondence between the index, the task, and the configuration in the operation management support apparatus 100. As shown in FIG. 6, a plurality of tasks are associated with one index, and a plurality of configurations are associated with one task. In the present embodiment, among the plurality of configurations, a configuration that satisfies the condition determined by the commander is specified.

  In the example shown in FIG. 6, as a subject corresponding to one index "long travel time between stations", "predetermined travel time optimization" and "actual travel time optimization" exist. And "diagram making device" exists as a configuration corresponding to "predetermined travel time optimization", "drive support device", "operation management device", "operation adjustment" as a configuration corresponding to "real travel time optimization" "Device" exists. Then, in the operation management support apparatus 100 of the present embodiment, it is determined whether the configuration specified according to the priority satisfies the condition (effect and cost) determined by the commander. In the example shown in FIG. 6, the value of the operation management support device 100 is calculated in the order of “diagram creation device”, “drive support device”, “operation management device”, and “operation adjustment device”. Then, when the calculated value satisfies the condition set by the commander, the configuration in which the value is indicated is to be corrected.

  Although the example shown in FIG. 6 has described the example in which the task and the configuration are selected according to the priority, it is not limited to the method of selecting according to the priority. For example, when the task extraction unit 113 extracts “predetermined travel time optimization” and “actual travel time optimization” as the tasks, “predetermined operation according to the selection operation from the commander via the support operation reception unit 119 One of the travel time optimization and the actual travel time optimization may be selected.

  The output unit 117 outputs an instruction to correct the configuration to be corrected. For example, the instruction for correction may be, for example, a corrected program used in the configuration or voice information output from the station facility 203. In addition, it may be a request for ordering of the configuration.

  The support operation reception unit 119 receives an operation from the commander. The support operation reception unit 119 according to the present embodiment performs processing related to index extraction in the index extraction unit 112, task extraction in the task extraction unit 113, specification in the specification unit 114, and value calculation in the value calculation unit 116 according to the received operation. I do.

  Next, an overall flow of processing in the operation management support apparatus 100 of the present embodiment will be described. FIG. 7 is a flowchart showing the procedure of the above-described process in the operation management support apparatus 100 of the present embodiment.

  First, the input unit 111 performs input processing on the actual result diamond data 181 and the predetermined diamond data 182 (S701).

  Next, the analysis unit 118 performs analysis processing based on the difference between the actual result diamond data 181 and the predetermined predetermined diamond data 182 (S702).

  Then, the index extraction unit 112 refers to the index database 101 and extracts an index according to the analysis result (S703).

  Next, the task extraction unit 113 extracts a task corresponding to the index with reference to the task database 102 (S704). When there are a plurality of issues corresponding to the index, the issues are extracted in consideration of the priority.

  Then, the identifying unit 114 refers to the configuration database 103 to identify the configuration (within the operation management system 150) corresponding to the task (S705). When there are a plurality of configurations corresponding to the problem, the configuration is specified in consideration of the priority.

  Next, the evaluation unit 115 performs simulation when the specified configuration is corrected (S706).

  Then, the value calculation unit 116 calculates the value when the configuration is corrected based on the simulation result (S707).

  The value calculation unit 116 determines whether the calculated value satisfies a predetermined condition (S 708). If it is determined that the predetermined condition is not satisfied (S 708: No), the process is performed again from S 704.

  On the other hand, when it is determined that the predetermined condition is satisfied (S 708: Yes), the process ends. At this time, the output unit 117 may output an instruction for correcting the configuration to the operation management system 150.

(Modification)
In the first embodiment, the case where the correspondence relationship stored in the index database 101, the task database 102, and the configuration database 103 is one has been described. However, the index database 101, the task database 102, and the configuration database 103 may have a plurality of types of correspondence relationships. Therefore, in the modification of the first embodiment, it is assumed that the index database 101, the task database 102, and the configuration database 103 have different correspondences for each type of train. In the present embodiment, although the case where the type of train is each station stop and the limited express train will be described, the type of train is not limited to each station stop and the limited express train.

  The index database 101 of the present modification stores a reference value for each type of train. And the subject database 102 of this modification matches and memorize | stores a parameter | index and a subject for every type of train. And the structure database 103 of this modification matches and memorize | stores a subject and a structure for every kind of train.

  Then, based on the analysis result by the analysis unit 118, the index extraction unit 112 extracts an index using a reference value associated with the type of train (for example, each station stops or the limited express train) in the index database 101. Do.

  Furthermore, the task extraction unit 113 corresponds to the index in the task database 102 based on the type of train (for example, each station stops or the express train) in which there is a difference between the performance diamond data and the predetermined diamond data. Extract the assigned task.

  And specific part 114 matches with a subject according to a kind of train (for example, each station stop or an express train) in which a difference has arisen between performance diamond data and predetermined diamond data in configuration database 103. Identify the configuration that is being

  The subsequent processes are the same as those in the first embodiment, and the description thereof is omitted. In the present modification, the configuration according to the type of train can be specified. Thereby, higher effects can be obtained in delay reduction and cost reduction.

Second Embodiment
In the first embodiment, an example in which the index is extracted using the reference value stored in the index database 101 and the task is extracted based on the correspondence relationship stored in the task database 102 has been described. However, the first embodiment is not limited to the provision of the index database 101 and the task database 102. Thus, in the second embodiment, the case where the index database 101 and the task database 102 are not provided will be described.

  FIG. 8 is a block diagram showing a configuration example of the operation management support device of the present embodiment. As shown in FIG. 8, in the operation management support apparatus 800, the index database 101 and the task database 102 are deleted as compared with the operation management support apparatus 100 of the first embodiment, and the index extraction unit 112 is an index extraction unit. In this example, the task extraction unit 113 is changed to 801 and the task extraction unit 802 is changed.

  The index extraction unit 801 includes an analysis unit 811. The analysis unit 811 tabulates the performance diamond data and the predetermined diamond data, and counts the average, variance, and the like of the departure times at all the stations in the target line area of the operation management system 150. For example, the analysis unit 811 calculates the delay of the departure time according to the following equation (1).

Delay time (seconds) = Actual schedule of each train (station arrival / station departure) time
-Predetermined diagram of each train (station arrival / station departure) time ... (1)

  Then, the index extraction unit 801 extracts, among the average and the variance of the delay of the departure time, the one with the highest average and the one with the highest variance as the index. For example, when the target line wards include stations A to H, the index extraction unit 801 extracts the average delay of the departure time of the station E and the variance of the delay of the departure time of the station F as an index.

  The task extraction unit 802 extracts optimization of the departure time as an issue from the average delay and variance of the departure time. For example, when the index extraction unit 801 extracts the average delay of the departure time of the station E as the index, the task extraction unit 802 extracts the appropriate stopping time of the station E as the task. As another example, when the index extracting unit 801 extracts the variance of the delay of the departure time of the station F as the index, the task extracting unit 802 extracts the appropriate stopping time of the station F as the task. .

  Then, the identifying unit 114 refers to the configuration database 103 and identifies a configuration corresponding to the extracted task. In the present embodiment, the configuration corresponding to the task is specified based on the correspondence shown in FIG. For example, the specification unit 114 specifies the diagram creation device 206 as a configuration corresponding to the appropriate stopping time of the station E, and the station facility 203 or the operation management device as a configuration corresponding to the actual stopping time of the station F. Identify 205. The subsequent processing is the same as that of the first embodiment, and the description will be omitted.

  In the second embodiment, since data does not have to be stored in the index database 101 or the task database 102 as in the first embodiment, the operation management support apparatus 100 is stored in the data in the initial operation state. It can be used to optimize the operation management system 150 in the case where it is not.

  Furthermore, since the index database 101 and the task database 102 are unnecessary, the operation management support apparatus can be simplified and the operation management system 150 can be optimized efficiently.

  In addition, calculation of statistics for actual results diamond data and predetermined diamond data when extracting the index requires considerable calculation time, but since the computer processing capacity in recent years has improved, there is no problem with the calculation load Conceivable. Moreover, it is thought that more effective index candidate extraction is also possible by examination of application of related techniques for extracting feature quantities from a large amount of data, such as data mining technology.

  The analysis unit 811 of the operation management support apparatus 800 may divide and collect data items specific to the railway system, such as a row number, a station, and a time zone. In this way, indexes can be efficiently extracted from a large amount of data.

Third Embodiment
In the embodiment described above, the case of correcting the configuration of the operation management system 150 has been described. However, in order to improve the operation management system 150, the present invention is not limited to only the modification of the configuration of the operation management system 150, and may be combined with other controls.

  FIG. 9 is a block diagram showing a configuration example of the operation management support device of the present embodiment. As shown in FIG. 9, the operation management support apparatus 900 is an example in which a system analysis unit 901 is added as compared with the operation management support apparatus 800 of the second embodiment.

  In the present embodiment, an operation adjustment is performed in the operation management system 150 in real time. For this reason, the input unit 111 performs input processing of the current timetable diamond data in real time.

  Furthermore, the operation adjustment device 204 of the operation management system 150 is provided with an operation adjustment function 950 that functions in accordance with an instruction from the system analysis unit 901.

Energy saving can be realized.

Fourth Embodiment
The real-time operation adjustment is not limited to the example shown in the third embodiment. Therefore, in the fourth embodiment, a case where the operation adjustment is performed based on the performance diamond data will be described.

  FIG. 10 is a block diagram showing a configuration example of the operation management support device of the present embodiment. As shown in FIG. 10, in the operation management support device 1000, an operation result data storage unit 1001 and a drive arrangement result data storage unit 1002 are added as compared with the operation management support device 900 of the third embodiment. In this example, the index extraction unit 1011 and the system analysis unit 1012 are changed.

  Further, the index extraction unit 1011 extracts the drive arrangement performed by the operation adjustment function 950 from the analysis result based on the predetermined diagram data and the actual result diagram data performed by the analysis unit 811, and performs the operation arrangement It is registered in the data storage unit 1002.

  FIG. 11 is a diagram illustrating delay times stored in the operation result data storage unit 1001 according to the present embodiment. As shown in FIG. 11, a delay time is stored for each station at which each train stops daily, in other words, the difference between actual diamond data and predetermined diamond data is stored. The operation result data storage unit 1001 may store the situation when the operation was performed. For example, congestion status at a station or weather information may be stored.

  Further, in the operation result data storage unit 1001, an analysis result based on the delay time shown in FIG. 11 is also registered. For example, the index extraction unit 1011 accumulates, for example, the number of seconds between arrival and departure of stations A to D, and analyzes the tendency of arrival and departure delays.

  In the example shown in FIG. 11, although the start position, the start time, and the scale of the delay occurrence differ depending on the day, there are days having similar trends in multiple days. For example, in the 4 days of 4/21, 4/25, 5/8, 5/10, the delay is a day of a major disturbance of 100 seconds or more. In another example, 4/24, 4/26, 4/27, 4/28, 5/9, 5/11 are the days of normal disturbance.

  Then, the index extraction unit 1011 registers data that is the result of the delay time for each group according to the magnitude of the disturbance.

  Furthermore, the operation result data storage unit 1001 may store, for example, the delay time before the diagram revision and the delay time after the diagram revision.

  Then, the analysis unit 811 analyzes whether there is a change in the occurrence place of the delay, the time zone, the train, etc. by the diagram revision based on the difference between the delay time before the diagram revision and the delay time after the diagram revision. You may. Then, the analysis result may be registered in the operation result data storage unit 1001.

  FIG. 12 is a diagram exemplifying performance data of the drive arrangement stored in the drive arrangement result data storage unit 1002 according to the present embodiment. As shown in FIG. 12, the trains for which the operation adjustment has been performed and the operation adjustment performed for the trains are stored in association with each other on a daily basis. That is, in the operation rearranging result data storage unit 1002, information indicating the operation rearranging performed when the difference between the actual result diamond data and the predetermined period data occurs is stored.

  The system analysis unit 1012 includes a delay prediction unit 1013 and an operation arrangement extraction unit 1014. When the system analysis unit 1012 recognizes that the operation disturbance has occurred based on the current performance diagram data input from the operation management system 150 via the input unit 111, how the operation disturbance is, Analyze if it is a situation For example, it is analyzed whether it is delayed from the departure station, delayed due to many passengers, or injured.

  When the system analysis unit 1012 determines that the delay is caused by the operation disturbance, based on the current performance diamond data input via the input unit 111 and the operation performance data storage unit 1001. , To calculate the delay prediction results.

  In the present embodiment, when the delay prediction unit 1013 predicts with reference to the data stored in the operation result data storage unit 1001, if it is determined that there is a past situation similar to the current situation, the driving is performed. The organization extraction unit 1014 extracts the operation arrangement actually performed in the past similar to the current situation from the operation arrangement result data storage unit 1002.

  The delay prediction unit 1013 predicts, in real time, the change of the delay time after the current based on the current performance schedule data and the operation performance data storage unit 1001.

  First, the delay prediction unit 1013 determines whether the current situation is a major disturbance or a disturbance within a normal state, based on the present performance diamond data and the operation performance data storage unit 1001.

  FIG. 13 is a diagram illustrating the delay time up to the present time. In the example shown in FIG. 13, the cell 1301 has already been stored as a record. Then, the cell 1302 is to be predicted.

  In such a case, in the example shown in FIG. 13, the delay prediction unit 1013 determines that there is a disturbance within the normal state, and is stored in the operation result data storage unit 1001, 4/24, 4/26, 4/27. , 4/28, 5/9, 5/11 The average value of the delay time of the station D of the train 6 is calculated (for example, 90 + 40 + 80 + 40 + 40 + 70) / 6 = 60 seconds), and the delay prediction value is derived.

  Further, when the delay prediction unit 1013 determines that there is a large disturbance, the delay of the station D of the train 6 of 4/21, 4/25, 5/8, 5/10, which is stored in the operation result data storage unit 1001. An average value of time is calculated (for example, 160 + 150 + 460 + 290) / 4 = 265 seconds), and a delay prediction value is derived.

  As described above, in the present embodiment, the predicted delay value after the present is calculated based on the past results. In this way, it is possible to provide support information for operation realignment.

  In the example mentioned above, the example which made the average value computed based on the size of the delay of a prediction object day the delay predicted value was explained. However, the present invention is not limited to such a method of calculating the delay prediction value, and grouping may be performed more finely. Furthermore, grouping may be performed according to whether the delay increases or remains constant as time passes. In this way, the delay prediction that matches the actual results is obtained. Furthermore, machine analysis may be used when analyzing the performance schedule data. For example, a neural network may be used to predict the number of delay seconds for a designated train / station.

  The drive arrangement extraction unit 1014 extracts the drive arrangement corresponding to the change of the delay time after the current time predicted by the delay prediction unit 1013. The extracted operation arrangement may be output to the operation management system 150 via the output unit 117, or may be displayed to a commander who issues an operation control instruction.

  Further, when the operation arrangement extraction unit 1014 extracts the operation arrangement, the operation arrangement may be extracted after analyzing the past tendency by machine learning such as a neural network. Thereby, the proposal of more appropriate operation arrangement can be realized.

  The delay prediction unit 1013 and the operation arrangement extraction unit 1014 are not limited to the case where the above information is used, but may be seasonal information, or may be updated appropriately by learning data. You may This can improve the accuracy of the prediction.

  In addition, when performing registration in the operation result data storage unit 1001 and the operation rearranging result data storage unit 1002, the index extraction unit 1011 may perform registration after being further divided into groups. For example, the delay time and the operation control may be grouped for each season. In this way, it is possible to realize the operation arrangement according to the season.

  In the present embodiment, after delay change prediction is performed based on the operation result data storage unit 1001 and the operation rearranging result data storage unit 1002, operation rearranging is performed based on delay change prediction. did.

  As a result, the burden on the commander who performs operation adjustment can be reduced. Moreover, even when there is a difference in the learning level of the commander, it is possible to achieve uniform operation arrangement. In addition, even when the work of the commander is established, the same operation management as before can be realized. Also, automatic control can be realized by outputting an instruction from the system analysis unit 1012.

  Further, in the present embodiment, by performing the driving support, it is possible to bring the performance diamond data closer to the predetermined diamond data, so it is possible to reduce the number of corrections of the configuration of the operation management system 150.
