Information is associated and retained. Note that the determination result data 216 is created by the process shown in FIG.

Next, processing performed by the vehicle operation support device 110 will be described.

FIG. 11 is a diagram showing an example of a flowchart relating to processing performed by the creating unit 201. As shown in FIG. Such processing starts from step S1101.

In step S1102, the creation unit 201 reads the required specification data 211, the input item data 212, and the input data 213, which are input information. The contents read from the input data 213 may be changed by the user.

In step S<b>1103 , the creation unit 201 calculates the number of conditions to be executed by the calculation unit 202 from the input data 213 . As shown in FIG. 5, the input data 213 has correspondence between the type of the subject and the proficiency level (required time) of the subject for each stage. For 214, a fault condition is created that reflects the combination of the subject and the proficiency level.

In the example shown in FIG. 5, the input data 213 includes three types of target persons: "administration center personnel", "repair workers", and "drivers". There are two types of people. In addition, in the example shown in FIG. 5, "step 6" has information on the time required for movement work for the station where the failure occurred. Since the failure occurrence station is "station A" according to the required specification data 211 shown in FIG. 3, there is one piece of information "station A" as the "failure occurrence station". From this, as the specification reflection input data 214, the creation unit 201 creates eight failure conditions determined by (Equation 1).

2 information of "person in charge of management center" x 2 information of "repair worker" x 2 information of "driver" x 1 information of "fault station" = 8 ways (Formula 1)

FIG. 6 shows an example of eight failure conditions calculated by (Equation 1).

In step S1104, the creation unit 201 creates implementation conditions for each stage of each failure condition (condition). The execution condition includes information that serves as a trigger for changing information in the processing performed by the calculation unit 202 . For example, when changing the departure time of a specific train, when increasing the stopping time of a specific train, when a specific train arrives at a specific station, when changing the maximum speed of a specific train When the speed of a specific train reaches a specific value, when the cumulative amount of electric power sent by a specific substation exceeds a specified value, when a specific time comes, each There are cases where it is unconditionally implemented when it progresses to a stage.

In this embodiment, according to the requirement specification data 211 shown in FIG. 3, the occurrence time 312 "13:00" is the execution condition of "stage 1". Further, from the input data 213 in FIG. 5, the correspondence between the information targeted during the processing (execution of the computer simulation) of the calculation unit 202 and the contents targeted in the execution of the computer simulation is "step 4 ” to cancel the departure of the train that is stopping at the station or traveling to the next stop on the train schedule. "Set the departure time" so that the train departs from the station, and "Set the suspended train" for the train schedule in "Step 9". These are all carried out unconditionally at the time of progressing to each stage without having a specific condition, because there is no condition designation such as a train that is a condition at that stage. From this, the time when it progressed to the said stage becomes an execution condition. For this reason, by sequentially adding the required time 506 of the input data 213 shown in FIG. 5, which is information that restricts the time difference between the stages before and after each condition, to "13:00" of "stage 1", the time that becomes the execution condition is obtained. can be obtained. FIG. 7 shows an example of the implementation time, which is the implementation condition for each failure condition.

The procedure will be described by taking as an example a case of creating "failure condition 1" among the implementation times 702 of each failure condition 701 in the implementation time data 700 shown in FIG. Since the failure occurs at the occurrence time 312 "13:00" according to the requirement specification data 211 of FIG. 3, the implementation time 702-1 of "stage 1" is "13:00".

The execution time 702-2 of the next "step 2" is required for the process of "the terminal of the management center displays the failure of the signal device at the station" held in the input item data 212 of FIG. 4 from the occurrence of "step 1". Determined by time. Here, this information is uniformly set to "1 minute" for all failure conditions, is held in the input data 213, and the creation unit 201 acquires it in step S1102. Accordingly, the implementation time 702-2 of "stage 2" is "13:01".

The execution time 702-3 of the next "stage 3" is the time required for "the management center person in charge reports the failure to the person in charge of the management center". This is the case when the management center person in charge 604 is a "newcomer". In this case, the required time 506 is "5 minutes" from the input data 213 of FIG. 5, and the execution time 702-3 of "stage 3" is "13:06".

The implementation time 702-4 of "stage 4" is the time required for responding to "the management center staff instructs to stop operation on all lines" (the management center staff makes an operation decision in response to an instruction from the person in charge). According to the input data 213 of FIG. 5, the required time 506 is "5 minutes", and the execution time 702-4 of "stage 4" is "13:11".

The implementation time 702-5 of "Stage 5" is the time required for "arranging work for requesting repair work by the person in charge of the management center". According to the input data 213 of FIG. 5, the required time 506 is "5 minutes", and the implementation time 702-5 of "stage 5" is "13:16".

The implementation times 702-6 and 702-7 of "Phase 6" correspond to "the repair worker arrives at the faulty station and starts work" (work preparation and repair work for the repair worker to move to the faulty station). It takes time. Among these, the time required for work preparation is the occurrence location 313 "station A" from the required specification data 211 shown in FIG. 3, and the required time 506 ( travel time) is "10 minutes". Therefore, the execution time 702-6 of "stage 6" is "13:26". Further, in the "failure condition 1", as shown in FIG. 6, the repair worker 605 is a "rookie". In this case, the required time 506 is "15 minutes" from the input data 213 of FIG. 5, and the implementation time 702-7 of "stage 6" is "13:41".

The implementation time 702-8 of "Step 7" is the time required for "the repair worker completes the work at the faulty station and reports to the person in charge of the management center" (the person in charge of the management center reports the completion of work from the repair worker) time to receive According to the input data 213 of FIG. 5, the required time 506 is "3 minutes", and the implementation time 702-8 of "stage 7" is "13:44".

The execution time 702-9 of "Stage 8" is the time required to respond to "the person in charge of the management center instructs the resumption of operation on all lines" (until the train driver resumes train operation according to the instruction of the person in charge of the management center). time). In "failure condition 1", as shown in FIG. 6, the driver 603 is a "newcomer". In this case, the required time 506 is "2 minutes" from the input data 213 in FIG. 5, and the implementation time 702-9 of "stage 3" is "13:46".

The implementation time of "Stage 9" is the time required for "the person in charge of the management center to change the train schedule, such as setting the suspension of trains" is the time required for the adjustment to indicate the In the present embodiment, all conditions are out of the scope, so the description is omitted.

In step S1105, the creation unit 201 obtains the specification reflection input data 214 (implementation conditions) for each stage of each failure condition (condition). The correspondence between the information to be targeted during the execution of the computer simulation from step S1104 and the content to be targeted in the execution of the computer simulation is due to the fact that departure suppression is set for the train schedule in "step 4", and the "step 8" to set the departure time for the train schedule, and "step 9" to set the suspended trains for the train schedule. Further, "stage 9" is excluded from all fault conditions in this embodiment. Based on these, the specification reflection input data 214 includes two items, ie, the setting of departure suppression for the train schedule at "step 4" and the setting of the departure time for the train schedule at "step 8". An example of the specification reflection input data 214 for each failure condition is shown in FIG.

A case of creating "failure condition 1" out of the failure conditions 801 of the specification reflection input data 214 shown in FIG. 8 will be described as an example. From the input data 213 shown in FIG. 5, among the execution times 702 of each failure condition 701 of the execution time data 700, at the execution time 702-4 of "stage 4", the departure suppression is set in the train schedule, It can be seen that at execution time 702-9, the departure restraint is canceled and the departure time is set on the train schedule. That is, in the fault condition 801 "failure condition 1", the execution time 702-4 "13:11" of "phase 4" is set to the execution time 802-1 (departure suppression), and the execution time 702 of "phase 8" is set. -9 "13:46" is set as the implementation time 802-2 (operation resumed).

In step S1106, the creation unit 201 checks whether steps S1104 and S1105 have been performed for all failure conditions (conditions) and stages. If not implemented, the creation unit 201 returns to step S1104 and repeats the process, and if implemented, proceeds to step S1107.

In step S<b>1107 , the creating unit 201 saves the information read in step S<b>1102 in the input data 213 . For example, when the time required for the process of “the terminal of the management center displays the failure of the signal device at the station” is read and then changed, the changed content is saved in the input data 213 .

In step S<b>1108 , the creation unit 201 writes out the specification reflection input data 214 . The contents to be written are the information shown in the specification reflection input data 214 in FIG. Finally, the process ends in step S1109.

By performing steps S1101 to S1109, the creating unit 201 creates the specification reflection input data 214 from the required specification data 211, the input item data 212, and the input data 213. FIG. The specification reflection input data 214 includes train diagram data describing the arrival and departure times of trains (not shown) at each station, route data describing gradients, curves, etc. of routes on which trains (not shown) run, Includes train data describing the acceleration/deceleration performance of the train, power consumption, etc. Note that the train diagram data, route data, and train data are information used by the calculation unit 202 for calculations related to train operation, and publicly known information can be used.

Next, the calculation unit 202 performs calculations related to train operation with respect to the specification-reflected input data 214 for each failure condition created by the creation unit 201 and creates output data 215 . The calculation unit 202, for example, calculates the position and speed of the train (not shown) each time the train passes, and uses a known technique to obtain the power consumption and the accumulated value of the delay time (not shown).

In this embodiment, the calculation unit 202 updates the train schedule to the train schedule with departure inhibition set when the internal time reaches “stage 4” according to the specification reflection input data 214 shown in FIG. When "stage 8" is reached, the calculation is continued by updating to the train schedule for which the departure restraint has been canceled. FIG. 9 shows an example of the results of the number of trains operated per day and the power consumption as the output data 215 obtained for each failure condition. In addition to the "failure conditions 1" to "failure conditions 8" in which there is a signal device failure, the calculation unit 202 also performs calculations with "failure condition 0" in the case where no device failure occurs.

By using the specification reflection input data 214 shown in FIG. 8, the calculation unit 202 calculates the time from the occurrence time "13:00" when the equipment failure occurs to the execution time of "stage 4" when departure deterrence is set for each failure condition. Differences in train deterrence stations caused by each train running during this period, and differences in train operation status after "stage 8" when deterrence is canceled and trains resume running are considered in terms of the number of trains in operation, power consumption, etc. It can be reflected in the calculation.

Next, the determination unit 203 creates determination result data 216 from the required specification data 211 and the output data 215 . Processing performed by the determination unit 203 will be described with reference to FIG. 12 .

Here, from the required specification data 211 shown in FIG. 3, the target 320 is "2 cases", and the target value 322-1 is "105% or less of daily power consumption on failure-free operation days". , and the target value 322-2 is "95% or more of the number of trains in service on failure-free days". On the other hand, FIG. 10 shows an example of evaluation results of the number of trains operated per day and power consumption in the output data 215 shown in FIG.

FIG. 12 is a diagram showing an example of a flowchart relating to processing performed by the determination unit 203. As shown in FIG. Such processing starts from step S1201.

In step S1202, the determination unit 203 reads the required specification data 211 and the output data 215, which are input information.

In step S1203, the determination unit 203 calculates the operating number ratio for each failure condition (condition). The determination unit 203 calculates the operating number ratio using (Equation 2).

Number of operation ratio = number of operation with failure / number of operation without failure (Equation 2)

When calculating the fault condition 902 "failure condition 1" of the output data 215, the number of operation 903 "600" under "failure condition 0" corresponding to no failure and the number of operation under "fault condition 1" corresponding to failure From 903 "551", the operating number ratio is 551÷600=92% from (Equation 2).

In step S1204, the determination unit 203 calculates the power consumption ratio for each fault condition (condition). The power consumption ratio is calculated using (Formula 3).

Power consumption ratio = power consumption with failure / power consumption without failure (Formula 3)

When calculating the fault condition 902 "failure condition 1" of the output data 215, the power consumption 904 "193.8 MWh" of "fault condition 0" corresponding to no failure and the power consumption of "fault condition 1" corresponding to failure From the power 904 "205.3 MWh", the power consumption ratio is 205.3/193.8=106% from (Equation 3).

In step S1205, the determination unit 203 determines whether or not the target is achieved for each failure condition (condition). With respect to the target value 322 acquired in step S1202, under "failure condition 1", the operating number ratio is "92%" and the power consumption ratio is "106%". , and the target achievement pass/fail 1007 is set to “fail”. In the output data 215 shown in FIG. 9, the target value 322 of the required specification data 211 shown in FIG.

In step S1206, the determination unit 203 determines whether all failure conditions (conditions) have been performed. If not implemented, the determination unit 203 returns to step S1203 to repeat the process, and if implemented, the process proceeds to step S1207.

In step S<b>1207 , the determination unit 203 writes the determination result data 216 and transmits the determination result data 216 to the output unit 130 . The output unit 130 displays the determination result data 216. FIG. The determination result data 216 is, for example, as shown in FIG. The content displayed by the output unit 130 may be, for example, all information of the judgment result data 216 shown in FIG. information. Then, the determination unit 203 ends the processing in the next step S1208.

By using steps S1201 to S1208, the determination unit 203 creates determination result data 216 from the required specification data 211 and the output data 215, and the output unit 130 displays the determination result data 216. FIG.

With the above configuration, the vehicle operation support device 110 can generate the input item data 212 in FIG. 5 input data 213 and 8 fault condition combinations determined by the input data 213 of FIG. It is possible to acquire the target state and the conditions under which the target can be achieved, and acquire the conditions under which the target can be achieved for the request (not shown).

Here, the required time is associated with the proficiency level of the subject. may be associated with the type of communication device that performs information transmission and the processing time.

For example, in the input item data 212 shown in FIG. 4, regarding failure detection in "stage 2", the types of communication devices that perform information transmission between a signaling device (not shown) and the management center are "A", "B", and " FIG. 13 shows an example of the input data 213 when there are three types of input data 213. Compared to the input data 213 shown in FIG. 5, three types of communication devices corresponding to "stage 2" and the required time are added. 24 fault conditions are created.

3 information of "communication device" x 2 information of "person in charge of management center" x 2 information of "repair worker" x 2 information of "driver" x 1 information of "failure station" = 24 ways... (Formula 4)

Since the procedure after this is the same as the one that was skipped earlier, the explanation is omitted.

According to the present embodiment, the information that can specify each condition and the calculation result indicating the operation state of the vehicle for each condition are output in association with each other, so that the user can specify the target operation state. You can get achievable conditions.

(2) Second Embodiment According to the second embodiment, in the configuration of the vehicle operation support device 110 shown in the first embodiment, FIG. 4 corresponding to the target state of the required specification data 211 shown in FIG. A method of creating the input item data 212 and the input data 213 from the existing input item data 212 and the existing input data 213 when the input item data 212 shown in FIG. 5 and the input data 213 shown in FIG. In the following, a case where a request (not shown) is under consideration by the user (request under consideration) will be described as an example.

For example, using existing data (requirement specification data 211, input item data 212, and input data 213) corresponding to one or more requirements different from the requirements under consideration, requirement specification data corresponding to the requirements under consideration 211, input item data 212, and input data 213 are tentatively determined by the creation unit 201, and the results of the calculation unit 202 and the determination unit 203 are used to determine whether or not the target has been achieved. With regard to the content of the request form corresponding to the request specification data 211, the input item data 212, and the input data 213, it is possible to obtain the conditions for whether or not the target operation state can be achieved.

In the following, the configuration different from that of the first embodiment will be mainly described. Note that the processing of the calculation unit 202 and the determination unit 203 is the same as that of the first embodiment, so the description is omitted.

FIG. 14 is a diagram showing an example of a flowchart relating to processing performed by the creation unit 201. As shown in FIG. Such processing starts from step S1401.

In step S1402, the creation unit 201 reads the required specification data 211, the input item data 212, and the input data 213, which are input information. Among them, the input item data 212 and the input data 213 are information corresponding to different requests. Further, the requirement specification data 211 includes information corresponding to a requirement under consideration and information corresponding to a different requirement.

Requirement specification data 211, input item data 212, and input data 213 corresponding to different requests are the contents described in FIGS. 3 to 5 described in the first embodiment. omitted.

FIG. 15 shows requirement specification data 1500 corresponding to the requirements under consideration.

FIG. 15 is a diagram showing an example of required specification data 1500. As shown in FIG. Requirement specification data 1500 corresponding to the requirement under consideration has information of target state 1510 and goal 1520, similar to requirement specification data 211. FIG. Here, the target state 1510 is classified 1511 as "a failure occurred in a part of the platform door device at the station", as the occurrence time 1512 as "14:00", as the occurrence location 1513 as "Station C" on the line (not shown), as the occurrence facility Stored as 1514 is "failure of device corresponding to door 1 of inbound platform" (not shown).

In step S1403, the creating unit 201 associates the input item data 212 and the input data 213 corresponding to different requests by work type, and then separates and organizes them for each stage and stores them. The creation unit 201 performs sorting, for example, in which items are rearranged in accordance with data having the same content, magnitude relationships of numerical values, and the like. As a result of organizing, the creating unit 201 holds the input item data 212 and the input data 213 as the input item stage candidate data 1600 shown in FIG.

In step S1404, the creation unit 201 creates input item data 212 corresponding to the request under consideration from the input item stage candidate data 1600 corresponding to different requests. The creation may be performed by displaying each candidate held by the input item stage candidate data 1600 by the output unit 130 and selecting it using the input unit 120, or by selecting it and then modifying it using the input unit 120. You may

For example, the first stage is the stage where the classification 1511 of the requirement specification data 1500 corresponding to the request under consideration is "failure occurred in part of the platform door device of the station", and the creation unit 201 selects the closest (similar ) Select the status of the candidate 1601 "candidate 1" or the action item 403 "failure occurred in the signal device at the station". The user corrects the selected content to "failure occurred in part of the platform door device of the station" (corrects "signal device" to "platform door device"), thereby changing "step 1" data (input item data 212 and input data 213).

The second step is the step of detecting a failure, and the creation unit 201 selects “Candidate 2” from the input item stage candidate data 1600, “Terminal at management center displays failure of signal device at station”, The user modifies it to ``The terminal of the management center displays the failure of the platform door device of the station''. Further, the required time 506 is set by reflecting the specifications of the platform door device. Here, it is uniformly set to "1 minute".

The third stage is the stage of reporting the failure, and the creating unit 201 selects "Candidate 3" from the input item stage candidate data 1600, "The person in charge of the management center reports the failure to the person in charge of the management center". . If the user does not need to change the selected content (required time 506, etc.), the value at the time of selection may be applied as is.

The fourth step is the step of making operational decisions in response to failures. Here, we will explain the case where it is tentatively decided that "trains will not be stopped and the stop time will be uniformly increased by 1 minute for safety confirmation only at the station where the platform door system has failed without stopping train operation" as an implementation item in the request under consideration. From the input item stage candidate data 1600, "departure deterrence" of "candidate 4" is selected as information close to the tentatively determined action item. The user does not change the "train schedule" of the update target 507, and sets the update content 508 to "uniformly increase the stop time by 1 minute only at the station where the platform door device is broken".

The creation unit 201 repeats the above-described procedure as necessary to create the input item data 212 and the input data 213 corresponding to the request under consideration.

Steps S1405 to S1411 are the same as steps S1103 to S1109 in FIG. 11, which have been described for the creation unit 201 in the first embodiment, so description thereof will be omitted.

With the above configuration, even when there is no input item data 212 and input data 213 corresponding to the target state of the requirement specification data 211, the input item data 212 and the input data 213 corresponding to a different request (not shown) can be used. It has been explained that the input item data 212 and the input data 213 corresponding to the request under consideration can be created. Judgment result data 216 is created for the input item data 212 and the input data 213 corresponding to the request under consideration based on the contents of the first embodiment, and failure conditions for achieving the target of the requirement specification data 211 of the request under consideration are determined. can judge. Therefore, according to the procedure of the second embodiment, failure conditions that achieve the target 320 of the requirement specification data 211 can be determined even when the requirement is under consideration.

In steps S1403 and S1404, the procedure corresponding to the target request is selected and created from the result of sorting all the steps held by the input item data 212 corresponding to different requests. , but not limited to these.

For example, the user may copy the input item data 212 corresponding to a different request through the input unit 120, and edit such as changing the numerical value, inserting or deleting a step, and creating it.

Further, for example, the creation unit 201 creates input item stage candidate data 1600 in which the input item data 212 and the input data 213 are associated with each different request, classifies 1511 of the requirement specification data 1500, and inputs item stage candidate data. Calculate the degree of similarity with the state or action item 403 of 1600, and use the input item stage candidate data 1600 containing the state or action item 403 that is most similar (highest similarity) to the classification 1511 of the requirement specification data 1500 It may be selected as data.

As information for selection and copying, all stages of each request are classified by work type, and ratio information (for example, similarity) of each work type to the previous stage is created. The input item data 212 may be automatically selected corresponding to requests having a similar proportion of work corresponding to the request. Further, instead of automatic selection, the candidates may be displayed in order of close ratio, and the user may select manually.

According to this embodiment, it is possible to obtain the conditions for achieving the target operation state in the request under consideration.
