Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a train operation replanning plan preparation device in a train operation management system.

[Prior Art] Conventionally, in most railway companies, a dispatcher created a rearrangement plan by judging from station equipment, running time, etc., while looking at a train diagram drawn on paper.

On the other hand, as part of the operation management system only on the JNR Shinkansen as a preparatory step for preparing a rearrangement plan, there was one that proposed a train retreat plan to the dispatcher.

[Problems to be Solved by the Invention] However, in the former case, the work is highly dependent on empirical knowledge and requires skill, and there is no guarantee that optimal operation rescheduling will always be possible. In addition, when the schedule is disturbed, the ordering staff has to carry out a lot of work such as grasping the delay situation, preparing a schedule, and transmitting the order in a short time.
Moreover, incorrect judgment would delay recovery and cause a great deal of inconvenience to passengers.

In the latter case, when the evacuation station is changed, it is a method of judging from the sum of the delay times of the evacuation train and the passing train caused by it, and even if it is good locally, it is appropriate considering the operation of all trains. In many cases, it was not practical because it was not possible to arrange operations such as suspension or transfer simply by changing the evacuation relationship.

Recently, due to the introduction of operation management system, etc., the grasp of delay situation and the transmission of commands have been considerably automated,
Creating a rescheduling plan is still a heavy burden on the dispatcher.

The present invention has been made to eliminate the above-mentioned drawbacks of the conventional ones, and while always considering the operation of all trains, a rescheduling plan including a change of shelter, a transfer, a change of operation, and suspension of operation is prepared and its simulation is performed. By displaying the result, it is an object of the present invention to provide a train operation rescheduling plan preparation device that can reduce the burden on the dispatcher when preparing a rescheduling plan and can shorten the time to restore the schedule. is there.

[Means for Solving Problems] The train operation rescheduling plan creating apparatus of the present invention is a simulator 1 that inputs information such as time and outputs a simulation result, and is connected to this simulator 1 to save each train. The simulator 1 comprises a diamond database 2 that records the possibility of changing train operations such as station changes and transfers and the conditions for making such changes, and a display device 3 connected to the simulator 1. , When the train operation is disturbed, enter the delay time that has occurred as the operation start time or the expected operation restart time as the above information,
After obtaining the forecast timetable for the case where the train was operated without any change in operation after restarting the operation, from this obtained forecast timetable, the possibility of moving up the train shelter station and the dependency of the shelter relationship were calculated. While creating a rescue plan, while seeking the delay of the delayed train group at each station for this created rescue plan,
The conditions for changing trains stored in the above-mentioned train database 2 are compared with each other to prepare a plan for changing trains. Further, with respect to the prepared plan for changing trains, future prediction of train operation, delay time, etc. The evaluation amount and the simulation result are obtained and output to the display device 3 to be displayed as a rescheduling plan.

[Operation] When train operation is disturbed, the generated delay time and operation start time, or expected operation restart time are input to the simulator 1 as information. As a result, the simulator 1 first obtains a prediction diagram when the vehicle is operated without any change of operation after the operation is restarted. Next, the evacuation plan of the evacuation station is created by obtaining the possibility of moving up the evacuation station of the train and the dependency of the evacuation relationship from this prediction diagram. Next, while obtaining the delay of the delayed train group at each station with respect to the evacuation plan, the conditions for changing the operation stored in the timetable database 2 are compared to create a timetable change plan. Finally, the future prediction of train operation and the evaluation amount such as delay time are calculated for this timetable change plan. And simulator 1
Outputs the future prediction and the evaluation amount, which are simulation results, to the display device 3 and displays them as a rescheduling plan.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a train operation replanning plan creating apparatus. In FIG. 1, reference numeral 1 is a simulator, 2 is a diagram database that records the possibility of changing train operations such as changing train stations for each train, and the conditions for making such changes, and 3 is a display device. The diamond database 2 and the display device 3 are connected to the simulator 1.

When the train operation is disturbed, the simulator 1 inputs the generated delay time and operation start time, or expected operation restart time as information, and operates without any change of operation after operation restart The demand schedule of the train station is calculated from the obtained train schedule and the possibility of moving up the train station and the dependency of the train relation are calculated. While comparing the conditions for operation changes stored in the above-mentioned timetable database 2 while obtaining the delay of the delayed train group at each station,
The schedule change plan is created, and the future prediction of train operation and the evaluation amount such as the delay time are obtained as the simulation result for the created schedule change plan, and are output to the display device 3 for rescheduling. It is displayed as a plan.

Next, the operation of the train operation rescheduling plan creating apparatus according to the present invention will be described first.
This will be described in detail with reference to the drawings and the flowchart shown in FIG.

At the beginning, for example, 10 departures or arrivals of J trains at station I
If the generated delay and the operation start time are given to the simulator 1 as information such as the delay by a minute (step
S1), the simulator 1 first obtains a prediction diagram when the vehicle operates without any change in operation after the operation is restarted (step S2). Next, the simulator 1 sets, from the above-obtained predicted timetables, trains that are delayed or trains that pass or stop later than the planned timetable in the delayed train group, and set the evacuation relationship. It is classified into those that can be implemented at the time according to the plan schedule (the set of which is T) and those that cause a delay (the set of which is F) (step S3). Here, if only the saving relationship of the set T is changed, the delay time only increases. Therefore, for the purpose of creating a rescheduling plan with a shorter delay time than when the operation rescheduling does not make at least any change, only the evacuation relationship of the set F needs to be changed. Then, if the evacuation relationship of the set T can still be implemented according to the planned timetable in the changed forecast timetable, it is guaranteed that the evacuation relationship of the set T may be excluded from the change target. Further, the saving relationship of the set F is classified into the following two (step S4).

Set F1 can be moved up Set F2 cannot be moved up Set F1 is a shunting relationship in which the above-mentioned delayed train group waits with the preceding train, and shunting (changing the shunting station to another station in the direction in which the train is traveling) Otherwise, the preceding train will have to wait longer than planned for the passing train. If the delay of the passing train is determined, it can be determined at which station the delay time should be minimized from the station equipment and the running conditions of the train.

Further, the set F2 has a saving relationship other than the set F1, and this is further classified into the following two (step S5).

Set F2-1 Dependence relationship Set F2-2 Dependence relationship Here, there is a dependence relationship that two trains having a shunting relationship belong to the set F before the shunting relationship in time. If you have In other words, even if the evacuation relationship that has a dependency relationship is similar to the evacuation relationship that can be carried forward, if the evacuation relationship before that is fixed, at which station the delay time will be the minimum if the evacuation relationship is saved based on the station equipment and train running conditions. Can be determined. Due to the above, in the creation of a save plan, only for the save relationship of the set F2-2 that cannot be uniquely determined, for each save relationship, the station equipment and the delay occurrence time are used to determine to which station the save can be postponed. ,
Create a plurality of evacuation plans (step S6).

Next, the simulator 1 obtains the delay of the delayed train group at each station for each of the escape plans created as described above (step S7), and changes the timetable recorded in the timetable database 1 Check the conditions, and if the conditions are met, change the evacuation station, transfer, change the operation, or cancel the operation (step
S8), to create a schedule change plan (step S9). In the timetable database 1, for example, the I train evacuates the J train at the K1 station, but if the J train arrives at the K station is delayed by t1 seconds, it is changed to the K2 station. Record the possibility of changing the transfer station, transfer, and train operation and the conditions for that. This condition is determined based on station equipment and running conditions, but may be rewritten in consideration of the mission of each train based on the empirical knowledge of a skilled dispatcher.

Next, the simulator 1 predicts the train schedule for the schedule change plan created as described above (step S1).
Along with 0), evaluation amounts such as delay time, time to return to normal schedule, number of timetable changes, number of delayed trains, etc. are calculated (step S11), and these calculation results are output to the display device 3 and displayed as a rescheduling plan. (Step S12).

In this way, by obtaining the prediction diagram after the delay occurs and introducing the concept of carry-over possibility and dependency,
It is possible to significantly reduce the number of evacuation relations to be considered, and it is possible to create a schedule change plan based on the evacuation plan in a short time. Accordingly, the dispatcher may adopt the most suitable operation rescheduling plan based on the estimated train schedule and the evaluation amount for each schedule change plan.

However, in the above embodiment, the delay of the arrival and departure time at the station has been described, but the delay due to the interruption of the line section on the route or the temporary speed limitation can be similarly processed.
In addition, the timetable database 1 stores the timetable changes and the conditions that can be performed at a station with an I train. Therefore, in addition to the change, transfer, and operation change of the evacuation station described above, for example, at an intermediate station. It is possible to set the timetable changes such as suspension of operation and warehousing.

In the above, the case of creating a traffic rescheduling plan for the input delay and operation start time has been described, but the present invention is not limited to this, and can be incorporated into an existing operation management system to constantly monitor train operation. Check and update the current position from the result,
It is possible to create and display a rescheduling plan by operating when a delay occurs and inputting only the expected operation start time after the delay. At this time, it may be used for unmanned operation rescheduling by automatically determining from the simulation result and the evaluation amount. Further, since it is expected that there will be a shortage of skilled persons in the future, it may be used for education of the dispatcher.

[Effects of the Invention] As described above, the train operation rescheduling plan creating apparatus of the present invention records the possibility of changing train operations, such as the change of the shelter station and the transfer of each train, and the conditions for making the change. When the train database is disturbed by the timetable database, display device and train operation, input the delay time and operation start time, or expected operation restart time, etc. as information and do not change the operation at all after restarting operation. The forecast schedule for when the train was operated was calculated, and from this obtained forecast diagram, the escape plan for the train station was created along with the possibility of raising the train station and the dependency of the train relationship. While seeking the delay of the train group delayed at each station in response to the evacuation plan, compare the conditions for operation changes stored in the above timetable database to create a timetable change plan For the proposed timetable change plan, a future prediction of train operation and an evaluation amount such as delay time are obtained as the simulation results, output to the display device, and displayed as a rescheduling plan. The load on the dispatcher who carries out operation rescheduling is greatly reduced, and the time required to restore the normal schedule can be shortened. Therefore, the influence of train operation disturbance on passengers is also reduced. In addition, there is a great effect on labor saving by educating the dispatcher and automating the rescheduling.
