It is the current train plan that is currently used by the company, that is, schedule information. As shown in FIG. 3, the current train plan 210 is a collection of records in which values such as up / down, stop station, start station, start time, and end time are associated with each other using a train number as a key. .

  FIG. 4 is a diagram showing an example of data of the current vehicle operation plan 310 of the present embodiment. The current vehicle operation plan 310 is data that the diagram information calculation unit 111 of the diagram correction plan generation system 100 acquires from the vehicle operation plan management device 300 and stores in the memory 103 or the storage device 101. This is information on the current train vehicle currently operated by the railway company or the like in accordance with the current train plan 210 described above. As shown in FIG. 4, the current vehicle operation plan 310 uses the train number common to each record of the above-described current train plan 210 as a key, the number of trains of the vehicle, the forwarding setting frequency which is the frequency of forwarding the vehicle, the vehicle This is a set of records in which values such as the inspection frequency and the vehicle warehousing frequency are associated with each other.

  FIG. 5 is a diagram illustrating an example of data of the current crew member operation plan 410 of the present embodiment. The current crew member operation plan 410 is data that the diagram information calculation unit 111 of the diagram correction plan generation system 100 acquires from the crew member operation plan management device 400 and stores in the memory 103 or the storage device 101. This is information on current crew members currently operating in accordance with the above-described current train plan 210 and current vehicle operation plan 310 by a railway company or the like. As shown in FIG. 5, the current crew member operation plan 410 is a set of records in which values such as possession licenses, assignments, flight boarding, and working conditions possessed by the crew members are associated with each other using the crew number as a key. Yes.

  In addition, the point pattern table 124 used by the correction policy input unit 110 described above is stored in the storage device 101 when the input device 105 receives an instruction from the user regarding the diamond information correction policy. As shown in FIG. 6, this score pattern table 124 indicates the degree of importance of each item such as the train delay probability, average boarding rate, fare revenue, vehicle maintenance cost, and crew labor cost, It is a table that stores a plurality of patterns of revision policy specified in. For example, assuming that the total score of the evaluation scores for each item is 100, if the correction policy is “01”, the importance of each item is: train delay probability: average occupancy rate: fare revenue: vehicle maintenance costs: crew personnel Expenses = 20: 20: 20: 20: 20 are specified, and a correction policy is shown so that the importance is equal among the items. Similarly, if the revision policy is “02”, the importance of each item is: train delay probability: average boarding rate: fare revenue: vehicle maintenance costs: crew personnel costs = 28: 18: 18: 18: 18 It is defined and indicates a revision policy that emphasizes the probability of train delay. The correction policy input unit 110 receives an instruction from the user as to which of the items in the score pattern table 124 is to be emphasized.

  Further, the diagram information calculation unit 111 uses a determination threshold value table 126 shown in FIG. The determination threshold value table 126 is a table that is a condition for achieving the evaluation score, and as shown in FIG. 7, the required minimum score of the evaluation score and the evaluation score between each item such as the train delay probability and the fare revenue.

Is preferable.

  A correction pattern table 127 shown in FIG. 8 is stored in the storage device 101 as a table used by the diagram information calculation unit 111. The correction pattern table 127 is a table that defines a plurality of correction contents for the diamond information for each diamond information correction policy. Specifically, using the identifier of the correction policy common to the point pattern table 124 of FIG. 6 as a key, an increase / decrease pattern of the number of trains, an increase / decrease pattern of the number of trains, an operation pattern of a train such as a travel route or a stop station, and the like It is a set of records in which patterns of correction contents of diagram information such as an increase / decrease pattern of the number of crew assigned to vehicles are associated. In the example of the correction pattern table 127 shown in FIG. 8, “U1” is used for the content that increases the number of trains by one, “U2” is the content that increases the number of trains by two, and the content for reducing the number of trains by one. Is “D1”, and the content to be reduced by two is “D2”.

  In such a correction pattern table 127, when a pattern that increases the number of trains or the number of trains is adopted and a diamond correction plan (including candidates) is generated, the number of passengers should increase. An increase in the evaluation score is expected for the item “income”. On the other hand, many vehicles will be operated with a dense schedule, which will lead to an increase in the frequency of vehicle maintenance and the number of crew, so the items related to “vehicle maintenance costs” and “crew personnel costs” in the revised policy A decline in the evaluation score is expected.

  In the correction pattern table 127, a plurality of records are associated with one correction policy, and the priority order between the records is defined. In the example of FIG. 8, a total of five records “01” to “05” are associated with the correction policy “01”.

--- Example of processing procedure 1 ---
Hereinafter, the actual procedure of the diamond correction plan generation method in the present embodiment will be described with reference to the drawings. Various operations corresponding to the diamond correction plan generation method described below are realized by a program 102 that the diamond correction plan generation system 100 reads into the memory 103 and executes it. And this program 102 is comprised from the code | cord | chord for performing the various operation | movement demonstrated below.

  FIG. 9 is a flowchart showing a processing example 1 of the diagram correction plan generation method in the present embodiment. Here, first, an overall flow of the diamond correction plan generation method of the present embodiment will be outlined. The flow shown here is a flow when only one diamond correction plan is generated.

  First, the correction policy input unit 110 of the diagram correction plan generation system 100 reads screen data stored in the storage device 101 in advance, displays the screen data on the output device 106, and displays the diamond information correction policy of the user on the corresponding screen. An instruction is accepted (S0001).

  Here, the screen shown in FIG. 17 can be assumed as a screen for accepting the correction policy by the user. A screen 1000 shown in FIG. 17 includes a display column 1010 for enumerating items of train delay probability, average boarding rate, fare revenue, vehicle maintenance costs, and crew labor costs, radio buttons 1020 corresponding to the items, and a decision button. 1030. The user performs a click operation on the corresponding radio button 1020 and presses the decision button 1030 in order to select an item to be emphasized as a correction policy among the items indicated by the display column 1010. The correction policy input unit 110 acquires the information of the corresponding item corresponding to the clicked radio button 1020 as the correction policy in response to pressing of the determination button 1030.

  Next, the diagram information calculation unit 111 executes a diagram simulation, that is, the train operation simulation described above (S0002), and based on the simulation result obtained thereby and the correction policy obtained in step S0001 described above, An evaluation score is calculated (S0003).

  Further, the diagram information calculation unit 111 checks the evaluation score calculated in step S0003 against the determination threshold value table 126 to make a pass / fail determination (S0004), and fails or does not satisfy the achievement condition (S0004: NG). Then, a correction pattern corresponding to the correction policy specified in step S0001 is selected from the correction pattern table 127 (S0005), and a diamond correction plan is created using this correction pattern (S0006).

  Subsequently, the diamond information calculation unit 111 performs the diamond simulation of step S0002 again on the diamond correction plan created in step S0006 described above, and repeats the subsequent steps S0002 to S0004. As a result of the determination in step S0004 regarding the schedule correction plan, if the result is a pass (S0004: OK), the diagram information calculation unit 111 displays each current plan management device (train plan management device 200, vehicle operation plan management device 300, crew member operation plan management device). 400), a diamond correction plan is transmitted (S0007), and the flow ends.

  The user of the diagram correction plan generation system 100 in the present embodiment only needs to first select a diamond correction policy from the list on the screen 1000, and the diamond correction plan generation is executed regardless of the user's knowledge and skill level. Will be. From this point, compared with the conventional situation in which the diamond information is evaluated and corrected manually, it is easier to assign the user in charge and execute the diamond correction, and the usability of the diamond correction plan generation system 100 is also improved. Become.

--- Processing procedure example 2 ---
Next, details of each process of the diamond simulation (S0002) and the calculation of the planned score (S0003) in the flow of FIG. 9 described above will be described with reference to the drawings. FIG. 10 is a flowchart showing a processing example 2 of the diagram correction plan generation method in the present embodiment.

  In this case, the diagram information calculation unit 111 receives the current train plan 210, the current vehicle as the latest plan information from each current plan management device (the train plan management device 200, the vehicle operation plan management device 300, the crew member operation plan management device 400). Each data of the operation plan 310 and the current crew member operation plan 410 is acquired (S0101).

  Subsequently, the diagram information calculation unit 111 gives the latest plan information 210, 310, 410 acquired above to the simulation program 112, performs a diagram simulation for a predetermined period (S0102), and estimates the number of times and time when train delay occurs. , The number of passengers expected for each train, the fare revenue according to the expected number of passengers, the frequency and content of vehicle maintenance according to the train operation schedule, the number of crew required according to the train operation schedule and operational vehicles, etc. Estimate the value.

  Next, the diagram information calculation unit 111 calculates the train delay probability (S0103), the average boarding rate (S0104), the fare revenue calculation (S0105), and the vehicle maintenance cost calculation (S0106) based on the simulation results described above. The calculation of the crew labor cost (S0107) is carried out. Among these, the train delay probability can be calculated, for example, by dividing the number of occurrences of the train delay indicated by the simulation execution result by the number of trains or a predetermined period. The average boarding rate can be calculated by dividing the number of passengers expected in each train indicated by the simulation execution result by the total capacity of each train. The fare revenue can be calculated by multiplying the number of passengers expected for each train indicated by the simulation execution result by a predetermined average fare amount. Further, the vehicle maintenance cost can be calculated by multiplying the vehicle maintenance frequency indicated by the simulation execution result by the average cost for each maintenance. The crew labor cost can be calculated by multiplying the required number of crew shown by the simulation execution result by the average labor cost per person.

  Subsequently, the diagram information calculation unit 111 stores the calculated values obtained in the above-described steps S0103 to S0107 in advance in the storage device 101 according to each value (eg, the train delay probability is “0.1%”). The evaluation score is specified for items such as the train delay probability, the average boarding rate, the fare revenue, the vehicle maintenance cost, and the crew personnel cost (S0108).

  Further, the diagram information calculation unit 111 calculates the total score by adding the evaluation scores obtained in step S0108 (S0109). Further, the diagram information calculation unit 111 calculates the difference between the highest score and the lowest score among the evaluation scores as a score difference (S0110). The diamond information calculation unit 111 stores the evaluation score, the total score, and the score difference calculated in this way with a calculation order in the score table 125 (FIG. 16). The diagram information calculation unit 111 counts up this calculation every time step S0003 is executed, and sets it in the score table 125.

  The evaluation score value of each item obtained in step S0108 and the score difference value obtained in step S0110 are used for the determination in step S0004. In step S0004, the diagram information calculation unit 111 calculates the evaluation score regarding each item (train delay probability, average boarding rate, total fare revenue, vehicle maintenance cost, crew personnel cost) obtained as described above and each value of the above-described score difference. Is compared with a record corresponding to the season to which the predetermined period belongs in the determination threshold value table 126, and either of the evaluation scores of each item is below the necessary minimum score, or the score difference between each item It is determined whether or not the upper limit of the score difference is exceeded. This completes the detailed description of steps S0002 and S0003.

FIG. 11 is a flowchart showing a processing example 3 of the diagram correction plan generation method in the present embodiment.

  In this case, the diagram information calculation unit 111 uses the plan management devices 200, 300, and 400 for the data of the current train plan 210, the current vehicle operation plan 310, and the current crew member operation plan 410 obtained in step S0101 (FIG. 10). From the storage device 101 or from the storage device 101 (S0201). Note that the latest plan information obtained in step S0101 has not been corrected, and is defined as information of the correction order “01” as the first correction target. For the data of each plan defined as the modified circulation “01”, the diagram information calculation unit 111 stores the train plan table 121 in FIG. 13, the vehicle operation plan table 122 in FIG. 14, and the crew member operation plan table 123 in FIG. 15. Store.

  In addition, the diagram information calculation unit 111 subtracts 1 from the last correction sequence from the records corresponding to the correction policy in the correction pattern table 127 as the correction content corresponding to the correction policy received in step S0001. A pattern having the same priority order as the value is selected as a correction pattern (S0202). For example, if the steps S0005 and S0006 are executed for the first time, the final correction number is incremented to “02” (the initial state is the correction number “01” as described above), and the diagram information calculation unit 111 Selects a record obtained by subtracting 1 from “02”, that is, a record of priority “01” from the correction pattern table 127.

  Each record of the correction pattern table 127, that is, the correction pattern has contents for correcting the number of trains, the train pattern, the operation pattern, and the number of crew members as described above. Therefore, the diagram information calculation unit 111 uses the correction pattern selected in step S0202 described above to correct the number of trains (S0203), the operation pattern (S0204), the formation pattern (S0205), and the number of crew members ( S0206) is performed.

  Finally, the diagram information calculation unit 111 reflects the correction result of each of the above steps (S0202 to S0206) on each plan information of the correction order “01” obtained in step S0201 (S0207), and the correction number A diamond correction plan candidate “02” is generated and stored in the train plan table 121 of FIG. 13, the vehicle operation plan table 122 of FIG. 14, and the crew member operation plan table 123 of FIG.

  Each process of step S0201-S0207 mentioned above is repeatedly performed whenever it determines with evaluation score failing in step S0004 (FIG. 9). Therefore, each time such a repetition is performed, the diagram information calculation unit 111 counts up the correction times and lowers the priority order by one to select a correction pattern.

  In this way, the use of a correction pattern when generating a diamond correction proposal eliminates the need for complicated calculation processing, and it is possible to achieve a quick review and correction even in the correction of diamond information in which a large number of components are complicatedly related. It becomes possible. In addition, the degree of variation in the quality and accuracy of the diamond correction results caused by the user's knowledge and experience can be minimized.

--- Processing procedure example 4 ---
Next, a process for generating a plurality of diamond correction plan candidates will be described with reference to the drawings. FIG. 12 is a flowchart showing a process example 4 of the diagram correction plan generation method in the present embodiment. A difference from the flow shown in FIG. 9 is that when a pass determination is obtained in the score threshold pass / fail determination (S0004), a re-simulation necessity determination is performed (S0008), and processing is performed according to the determination result. It is a point to do. Therefore, the description of the processing having the same contents as the flow of FIG. 9 is omitted.

  In this case, in step S0004, the diagram information calculation unit 111 evaluates the items (the train delay probability, the average boarding rate, the total fare revenue, the vehicle maintenance costs, the crew personnel costs) obtained as described above and the above-mentioned scores. Each value of the difference is collated with the record corresponding to the season to which the predetermined period belongs in the determination threshold value table 126, and either of the evaluation scores of each item is below the necessary minimum score, or each item It is determined whether the score difference between them exceeds the score difference upper limit. As a result, if the result is acceptable (S0004: OK), the diagram information calculation unit 111 stores the corresponding diagram correction plan candidate in the storage device 101 as a diamond correction plan, and the number of stored diamond correction plans stored in the memory 103. Increments the value of.

  The diagram information calculation unit 111 compares the value incremented each time the diagram correction plan is stored with a predetermined or user-desired number of transmissions to determine whether the above-described value satisfies the number of transmissions, that is, Then, the re-simulation necessity determination is executed (S0008).

  In this determination, when it is determined that the above-described value satisfies the number of transmissions (S0008: n), the diagram information calculation unit 111 stores the data of the diagram correction plan stored in the storage device 101 for each current plan management device. (Train plan management apparatus 200, vehicle operation plan management apparatus 300, crew member operation plan management apparatus 400) are transmitted (S0007), and the flow is terminated. On the other hand, when it determines with the above-mentioned value not satisfy | filling the number of transmissions (S0008: y), the diamond information calculation part 111 returns a process to the above-mentioned step S0005, and repeats subsequent steps S0006-S0002-S0004.

  Note that the number of transmissions mentioned above depends on the nature of the region and the railway operator, such as whether or not there is an expert who can consider multiple schedule revision proposals, whether or not the examination period can be secured, and whether or not enough driving records have been accumulated. An appropriate value (1 or more) is set. By adopting such a form, it is possible to easily customize the processing contents and the system according to the characteristics of various countries that operate or apply the diagram correction plan generation system 100, and the schedule correction plan generation is efficient and reliable. I can do it.

  Although the best mode for carrying out the present invention has been specifically described above, the present invention is not limited to this, and various modifications can be made without departing from the scope of the invention.

  According to this embodiment, when reviewing train schedule information in which a large number of components are related in a complex manner, the user simply specifies a correction policy, and is not affected by individual user skills such as knowledge and experience. Uniform and objective evaluation of diamond information and generation of diamond correction proposals can be made quickly and efficiently. Accordingly, it is possible to efficiently generate a schedule correction plan with good quality by suppressing the personality related to the prior evaluation of train diagrams and the correction work based thereon.

  At least the following will be clarified by the description of the present specification. That is, in the diamond correction plan generation system, the arithmetic unit generates the diamond correction plan candidate, executes the train operation simulation based on the diamond correction plan candidate, until the evaluation score reaches the achievement condition, Each process of specifying the evaluation score based on the execution result of the simulation and collating the evaluation score with the achievement condition may be repeatedly executed. According to this, generation of a suitable diamond correction plan is efficiently and reliably executed without excessive labor and cost.

  Further, in the diagram correction plan generation system, the arithmetic device repeatedly executes each of the processes until the evaluation score reaches the achievement condition until the predetermined number of the diamond correction plans is obtained, A predetermined number of schedule correction proposals may be transmitted to the management device or a predetermined terminal. According to this, it is possible to present a plurality of diamond correction proposals to a high-skilled user who can judge whether the diamond correction proposal is good or bad, and to accurately respond to the user's needs.

  Further, in the diagram correction plan generation system, the correction pattern table in the storage device includes at least two or more of a train delay probability, an average boarding rate, a fare revenue, a vehicle maintenance cost, and a crew personnel cost as a schedule policy for schedule information. It is a table that prescribes the amendment contents of the diamond information for raising and lowering the value of each item as the amendment contents for the diamond information, and the arithmetic unit is configured to perform the simulation in the process of specifying the evaluation score. As data included in the execution results, it relates to at least two items of train delay probability, average boarding rate, fare revenue, vehicle maintenance costs, and crew personnel costs corresponding to the items of the correction policy defined in the correction pattern table. The data is checked against predetermined criteria, the score for the relevant item is specified, and In the process of generating a candidate for a candidate, the specified evaluation score is compared with the necessary minimum score of the evaluation score, which is an achievement condition regarding the evaluation score, and the upper limit of the score difference between the corresponding items, If any of the evaluation scores for each item is below the required minimum score, or if the score difference between the items exceeds the score difference upper limit, it is determined that the achievement condition has not been achieved, One of the correction contents associated with the received correction policy may be selected from the correction pattern table, and the diamond information may be corrected with the corresponding correction contents to generate a diamond correction proposal candidate. According to this, a schedule correction plan that matches the user's needs for important items in train operation management, such as train delay probability, average occupancy rate, fare revenue, vehicle maintenance costs, and crew labor costs, or management in railway operators. Can be generated quickly and efficiently.
