Description

  The present invention relates to a technique for supporting creation of a vehicle allocation plan in a railway depot.

  In the railway depot, each vehicle is inspected. Inspection of vehicles is performed based on an inspection plan that defines which vehicles are to be inspected and when. Further, at a railroad depot, vehicle allocation is performed to determine which vehicle is to be allocated to each train on the schedule. In the vehicle allocation, it is determined which vehicle is to be allocated to each train of a previously scheduled schedule based on a vehicle operation plan in which the operation of each vehicle is planned in advance.

  However, when the schedule is disturbed or when the inspection of the vehicle is delayed, it is necessary to change the vehicle assignment and the inspection plan defined in the vehicle operation plan. Further, if the operation and inspection plans of the vehicle are changed, the inspection plan and the operation plan of the next day may be affected.

  Patent Literature 1 discloses a technique for reducing the influence on the next day when using the vehicle for the operation of a rush train on the day, by narrowing down the usable vehicles by considering the operation and inspection type of the vehicle on the next day. ing.

JP 2014-151849 A

  However, the technology disclosed in Patent Literature 1 determines the allocation of vehicles based on the time required for the inspection on the day and the inspection plan for the next day. No consideration is given to the number of passengers, which is the number of passengers that should be able to be transported, and whether the vehicle satisfies the demand equipment required for the train at that time.

  For example, in the UK, it is common to provide catering services to commuters on trains during commuting hours. Therefore, it is preferable to give priority to a train equipped with a catering facility for implementing a catering service for a train during a commuting time. On the other hand, during the daytime, many passengers use trains for long-distance travel, and such passengers sometimes bring luggage or bicycles into the train. For this reason, it may be preferable to give priority to a vehicle equipped with a space where luggage and bicycles can be placed during the daytime. In the technique of Patent Document 1, it is not possible to perform vehicle allocation in consideration of such demand facilities.

  Also, on the depot side, the constraint itself, which is a condition for determining the vehicle allocation, may change according to the condition of the depot at the time when it becomes necessary to arrange a vehicle to be newly allocated to the train. For example, inspection plans and crew plans are relatively easy during the day, so if an additional vehicle is requested for alleviating congestion during the day, the schedule will be changed and the vehicle will be inspected. In some cases, it is possible to provide a vehicle that has been damaged. However, in the nighttime, the cost of providing vehicles is high because leaving the vehicle may cause additional work to the crew, such as forwarding the train, and the difficulty of conducting inspections due to the lack of skills and the number of maintenance workers. May be too sticky. In such a case, it may be better not to provide the vehicle in accordance with the schedule desired by the operator.

  If the company that operates the train (operating company) and the company that manages the vehicle (vehicle managing company) are different, depending on what kind of contract is concluded between those companies, Therefore, there is a possibility that the time period during which the vehicle can be provided may be limited. Also, if each vehicle depot has a different vehicle management operator, the operator may need to negotiate with each person in charge of multiple depots to find a depot that can provide vehicles under better conditions. is there. Such negotiations take time.

  The object of the present invention is a constraint imposed on a vehicle allocation defined for each depot, equipment that a vehicle defined for each time and route should have, the number of passengers that should be able to be transported by train, An object of the present invention is to provide a technology that supports performing vehicle allocation in consideration of costs required for vehicle operation.

  In order to achieve the above object, a vehicle allocation support system according to one aspect of the present invention is a vehicle allocation support system that supports work of allocating vehicles to a railway train, wherein the vehicle allocation support system is defined for each vehicle base. A constraint that manages a constraint condition indicating a matter to be satisfied when a vehicle at a base is assigned to a train and a facility condition indicating a facility that the vehicle to be assigned to the train should have, which is defined for each time and / or route. The management unit, together with the assignment execution request to execute the assignment of vehicles to the train of the train diagram, given information of the number of passengers that is the number of passengers that should be able to be transported by train, the constraint conditions and the equipment conditions By searching for vehicles that can be fulfilled and assigned to trains on the train schedule to be able to carry the passengers of the required number of passengers, A vehicle candidate extracting unit that extracts a candidate of a vehicle to be allocated to the train in a train diagram, a crew plan that is a replacement plan that is a plan related to vehicle interchange, and a crew plan that is a plan related to allocation of crew members to the train, for the extracted candidates And a work plan that is a plan related to work including vehicle inspection; and an impact determination unit that calculates an operation cost based on the degree of influence that is a degree of influence on the work plan, and the operation cost related to the candidate in the extracted candidates. And a display unit for displaying

  The main storage unit 12 stores information about the server device 10A in a nonvolatile manner.

  The input unit 13 is input by the user to the server device 10A when it is necessary to manually input information on the server device 10A.

  The output unit 14 causes the server device 10A to output information to the user when the information regarding the server device 10A needs to be output.

  The communication unit 15 is connected to the communication unit 15 of another server device via the network 70, and transmits information to and from the other server device.

  In this configuration, for example, the main control unit 11 is a CPU (Central Processing Unit) and a RAM (RANDOM ACCESS MEMORY), the main storage unit 12 is a hard disk, the input unit 13 is a keyboard, the output unit 14 is a monitor, and the communication unit is a communication unit. By realizing 15 with Ethernet (registered trademark), it is possible to configure a conventionally well-known device.

  FIG. 3 is a diagram showing a software configuration of the vehicle allocation support device 10 shown in FIG.

  As shown in FIG. 3, the vehicle allocation support device 10 shown in FIG. 1 includes a constraint management unit 101, a monitoring unit 102, a vehicle candidate extraction unit 103, an influence determination unit 104, base condition data 111, equipment condition Data 112, vehicle data 113, and vehicle allocation candidate data 114 are provided. These are software programs and data stored in the main storage unit 12 shown in FIG. 3, and are read into the RAM and executed by the CPU (processor) at the time of execution.

  The constraint management unit 101 includes a constraint condition, which is defined for each vehicle depot and indicates a condition to be satisfied when a vehicle at the depot is assigned to a train, and a vehicle to be allocated to the train, which is defined for each time or route. And equipment conditions indicating equipment to be managed. The constraint management unit 101 receives the input of the constraint condition of the base and the facility condition which is set for each time and which has priority over the vehicle, and stores them as the base condition data 111 and the facility condition data 112, respectively.

  The monitoring unit 102 monitors the assignment execution request notified from the inspection management device 50 or the operation management device 30. When the assignment execution request is notified from the inspection management device 50 or the operation management device 30, the monitoring unit 102 The vehicle candidate extraction unit 102 is operated.

  The vehicle candidate extraction unit 103 is notified of the assignment execution request from the inspection management device 50 or the operation management device 30, and is provided with information on the number of passengers, which is the number of passengers who can be transported by train, from the demand management device 20. In addition, the constraint information and the facility conditions managed as the base condition data 111 and the facility condition data 112 by the constraint management unit 101 with respect to the operation information for allocating the vehicle acquired from the operation management device 30 are satisfied, and the number of passengers of the demand number is transported. A search is made for a vehicle that can be assigned to the train on the train schedule so as to enable the search, thereby extracting a candidate of the vehicle to be assigned to the train on the train schedule.

  The impact determination unit 104 determines the vehicle candidate extraction unit 103 based on the inspection information acquired from the inspection management device 50 and the presence or absence of a change in the inspection plan determined by the plan creation device 40 for the candidate extracted by the vehicle candidate extraction unit 103. Quantitatively calculates the influence of the vehicle depot when the candidate extracted in is selected. Specifically, the impact determination unit 104 includes a replacement plan that is a plan related to vehicle accommodation, a crew plan that is a plan related to assignment of crew members to a train, and a work plan that is a plan related to work including vehicle inspection. The operation cost is calculated based on the degree of influence, which is the degree of influence on the system. In addition, when there is a change in the inspection plan in the base due to the selection of the vehicle candidate, the influence determination unit 104 causes the plan creation device 40 to calculate the plan again.

  Next, the relationship between the processing flow and the data in the vehicle allocation support system shown in FIGS. 1 and 3 will be described in detail.

  FIG. 4 is a diagram for explaining a relationship between a processing flow and data in the vehicle allocation support system shown in FIGS. 1 and 3.

  First, the constraint management unit 101 acquires the base condition and the facility condition input by the user, and updates the base condition data 111 and the facility condition data 112, respectively.

  Next, when the monitoring unit 102 receives a request to execute vehicle allocation from the operation management device 30 or the inspection management device 50, the monitoring unit 102 activates the vehicle candidate extraction unit 103. In addition, the monitoring unit 102 receives the execution request of the vehicle assignment, acquires the change schedule data from the operation management device 30, and transmits the changed schedule data to the vehicle candidate extraction unit 103. Further, when the monitoring unit 102 receives a request to execute vehicle allocation from the inspection management device 50, the monitoring unit 102 acquires vehicle inspection data and transmits the vehicle inspection data to the vehicle candidate extraction unit 103.

  Next, the vehicle candidate extraction unit 103 acquires the number of passengers for each time zone as the demand information from the demand management device 20 and the vehicle data 113 in the vehicle allocation support device 10, and A vehicle that can be allocated to the vehicle is extracted as an allocation candidate vehicle. The details of the vehicle data 113 will be described later. At this time, the vehicle candidate extraction unit 103 determines whether the constraint management unit 101 satisfies the constraint conditions and equipment conditions managed as the base condition data 111 and the equipment condition data 112 for each of the extracted allocation candidate vehicles. , The degree of satisfaction of the condition is determined.

  Next, the influence determination unit 104 determines the effect when a candidate train is allocated to the vehicle allocation candidate extracted by the vehicle candidate extraction unit 103. Specifically, it specifies how much the planned inspection plan, the occupancy plan of the track in the depot, and the human resource plan such as the on-site driver and crew will be changed by the vehicle allocation, and the plan change The operation cost of the vehicle depot is calculated from the work that occurs with the above, and the vehicle allocation candidate data 114 is updated. In addition, the difference of the operation cost from the planned plan is small, and the vehicle which has less influence on the vehicle operation due to the change has a higher priority.

  After that, the influence determination unit 104 transmits the vehicle allocation candidate data 114 to the display device 60 and displays it to the user. When the user selects a vehicle after confirming the displayed vehicle allocation candidate and the effect on the depot when the selected vehicle allocation candidate is selected, the display device 60 displays the information of the vehicle selected by the user on the operation management device. 30 and the inspection management device 50 are notified.

  FIG. 5 is a diagram showing a data structure of the base condition data 111 shown in FIG.

  The base condition data 111 shown in FIG. 3 manages the restriction of the vehicle base. As shown in FIG. 5, the base condition data 111 has a base ID 501 capable of uniquely specifying the vehicle base. An ID 502, a constraint 503, an evaluation value 504 of the constraint, and a priority 505 are stored.

  For the route ID 502, a route ID is set if the constraint is applied only to the route (T or TT in the example shown in FIG. 5), and if the constraint is applicable regardless of the route, the route ID is set using an expression such as "-". Make it possible. In the constraint 503, for example, the content such as whether or not vehicles are allocated when changing the composition of the vehicles constituting the train, the number of conditions for using the spare vehicles, and the like are set. The evaluation value 504 stores an evaluation value for determining the constraint set by the constraint 503. The evaluation value stores whether or not the constraint is applied (“Yes” or “No”), or a numerical value that can be used as an upper limit or a lower limit. The priority 505 is set according to the degree of priority, such as 1 if the constraint must be kept, and 2 if the constraint can be changed by adjustment.

  For example, the base condition data 111 shown in FIG. 5 will be described. In the first stage shown in FIG. 5, in the vehicle base having the base ID X, the vehicle formation is changed for the line having the line ID T and the vehicle formation is changed. Can be assigned, and the constraint condition at that time is set as a high priority of 1 (MUST). In the second stage shown in FIG. 5, in the vehicle base having the base ID X, the upper limit number of vehicles using the spare vehicle is 3 vehicles per day for an arbitrary route. Has a priority of 2. Further, in the third row shown in FIG. 5, in the vehicle base having the base ID X, it is possible to assign a vehicle under inspection for the route having the route ID TT. Is set as 3. In the fourth row shown in FIG. 5, in the vehicle base having the base ID of X, the operation cost when allocating a vehicle to the train is set to +2000 for the route having the route ID of T, and the constraint condition at that time has priority. The degree is set as high as 1 (MUST).

  FIG. 6 is a diagram showing a data structure of the equipment condition data 112 shown in FIG.

  The equipment condition data 112 shown in FIG. 3 stores the equipment conditions of the vehicle for different passenger demands for each route and time zone, and as shown in FIG. 6, the base condition data shown in FIG. It has a route ID 601 similar to 111 and stores a time zone 602 and an equipment list 603 for each of the route IDs 601.

  The time zone 602 stores a time zone in which a vehicle having the equipment described in the equipment list 603 is desired. The granularity of the time zone can be flexibly changed, and may be divided into weekdays and holidays. The equipment stored in the equipment list 603 indicates in-vehicle equipment and the number of trains. For example, there are Wi-Fi facilities, bicycle vehicles, wheelchair spaces, catering facilities, and the like. The equipment list can be freely set and can be changed later.

  For example, in the second row of the facility condition data 112 shown in FIG. 6, Wi-Fi and catering facilities are indispensable from 8:00 to 10:00, regardless of weekdays and holidays, and wheelchair facilities should be available if possible. It is set that the number of vehicles of eight or more is required.

  FIG. 7 is a diagram showing a data structure of the vehicle data 113 shown in FIG.

  The vehicle data 113 shown in FIG. 3 is data that can uniquely specify the attribute and state of the vehicle, and sets data that can be uniquely specified in the operation management device 30 and the inspection management device 50. As shown in FIG. 7, the vehicle data 113 includes vehicle attribute information including a format 702 indicating the type of the vehicle, a formation ID 703, and a supply number 704 indicating the number of people who can ride on the vehicle. The vehicle inspection information including the total mileage 705, the latest inspection completion date and time 706, and the vehicle state 707 are managed in association with the vehicle ID 701 set for each vehicle.

  The state 707 of the vehicle stores the train number if the train is operating and the number indicating the location if the train is present in the train depot. That is, the vehicle state 707 is information indicating where the vehicle is present. The number indicating the location of the vehicle in the depot is, for example, a track number or an inspection management number.

  In the case where the inspection cycle is controlled based on the vehicle inspection rule other than the mileage and the date and time, data items that can determine the necessity of the inspection may be set.

  FIG. 8 is a diagram showing a data structure of the vehicle allocation candidate data 114 shown in FIG.

  As shown in FIG. 8, the vehicle allocation candidate data 114 shown in FIG. 3 has the same vehicle ID 801 as the vehicle data 113 shown in FIG. 7, the constraint satisfaction number 802, the facility satisfaction number 803, and the excess number of rides 804. , The minimum preparation time 805, the inspection status on the day 806, the replacement plan influence 807, the crew plan influence 808, the work plan influence 809, and the operation cost 810.

  The number satisfying the condition based on the base condition data 111 is stored in the constraint satisfaction number 802, and the number satisfying the condition based on the facility condition data 112 is stored in the facility satisfaction number 803. The number of excess rides 804 stores the number that may not be supplied to the number of passengers acquired by the demand management device 20 by allocating the vehicle specified by the vehicle ID 801. That is, the excess number of passengers 804 indicates the number of passengers who cannot get on the vehicle, and therefore, it is preferable that the number is minus, as in the example shown in the third row of FIG. However, even if the number is negative, the larger the absolute value, the more wasted the capacity of the vehicle. The minimum preparation time 805 indicates a time required from when it is determined that the vehicle specified by the vehicle ID 801 is to be allocated to when the vehicle starts using the main line. Depending on the vehicle inspection status and the crew's plan, it may not be available immediately. Therefore, the result determined based on various plans and the state of the vehicle is stored. The inspection status on the day 806 stores the presence / absence of the inspection scheduled on the day when the vehicle is allocated, or whether the inspection is being performed. The replacement plan impact degree 807, the crew plan impact degree 808, and the work plan impact degree 809 are information necessary for the operation of the assigned vehicle, the inspection in the depot, and the management of the vehicle. This is a numerical representation of the degree of change that occurs when the relevant vehicle is assigned to the planned plan. The operation cost 810 is a numerical value of the total cost caused by the plan change, and is calculated from the replacement plan impact degree 807, the managing staff plan impact degree 808, and the work plan impact degree 809.

  Hereinafter, the operation of the vehicle allocation support system configured as described above will be described.

  First, the operation of the entire vehicle allocation support system will be described.

  FIG. 9 is a diagram showing an operation flow in the operation allocation support system shown in FIG. 1 until the vehicle allocation support device 10 outputs a vehicle allocation candidate and completes the allocation.

  In the operation assignment support system shown in FIG. 1, when the vehicle assignment support device 10 receives a vehicle assignment execution request from the operation management device 30 or the inspection management device 50 (step 901), first, the constraint condition of the base and the vehicle A vehicle allocation candidate that satisfies the condition is derived (step 902). The derivation of the vehicle assignment candidate will be described in detail with reference to FIG.

  After deriving the vehicle allocation candidate, the vehicle allocation support device 10 transmits the derived vehicle candidate to the display device 60 via the network 70, and causes the display device 60 to display the vehicle candidate.

  Thereafter, when the user operates the display device 60 to determine the vehicle to be allocated (step 903), the vehicle allocation support device 10 notifies the operation management device 30 of the determined vehicle information (step 904).

  If the assigned vehicle is not determined by the vehicle candidates displayed on the display device 60, the change information input by the user to the display device 60 is received (step 905), the process returns to step 902, and the assigned vehicle is returned again. A process for deriving candidates is performed.

  After the allocation vehicle is determined, the vehicle allocation support device 10 notifies the inspection management device 50 of whether the inspection plan has been changed (step 906).

  Next, the operation flow of the vehicle candidate extraction unit 103 shown in FIG. 3 will be described.

  FIG. 10 is a diagram for explaining the operation flow of the vehicle candidate extraction unit 103 shown in FIG. 3, and shows a detailed flow of the process in step 902 shown in FIG.

  First, the vehicle candidate extraction unit 103 acquires various information from the demand management device 20 and the operation management device 30 connected via the network 70 (step 1001). More specifically, the vehicle candidate extraction unit 103 acquires the number of demanded passengers for each time zone from the demand management device 20, and acquires the schedule data for allocating vehicles from the operation management device 30. It is assumed that the schedule data includes at least operation information such as a route name, operation time, first and last points, and whether or not an express train.

  Next, the vehicle candidate extraction unit 103 updates the state of each vehicle with respect to the vehicle stored in the vehicle data 113 and satisfies the required number of people and the schedule data obtained from the demand management device 20 and the operation management device 30 by satisfying the request. A vehicle that can be assigned to a time zone is extracted (step 1002). At this time, it does not matter whether the vehicle is staying at the depot or under inspection.

  Next, based on the base condition data 111 and the facility condition data 112, the vehicle candidate extraction unit 103 extracts a vehicle that satisfies at least one of the facility condition and the base constraint condition for the vehicle extracted in step 1002. (Step 1003).

  Next, the vehicle candidate extraction unit 103 calculates a difference between the number of demanded passengers acquired from the demand management device 20 and the number of supplied vehicles extracted in step 1003 (step 1004). This difference is the number of excess rides in the vehicle assignment candidate data.

  Next, the vehicle candidate extraction unit 103 generates, from the inspection management device 50, an inspection history indicating a history of inspections performed on all vehicles managed at the vehicle depot, and a plan of inspections to be performed on all vehicles. The vehicle inspection data including the inspection plan shown is acquired, and the inspection state of the vehicle extracted in step 1004 is specified (step 1005). The inspection state indicates whether or not each vehicle is inspected on the day (whether the inspection is planned on the vehicle allocation date) and, if the inspection is planned, whether the inspection is completed.

  After specifying the vehicle and the inspection state of the vehicle as described above, the vehicle candidate extraction unit 103 sets the time when the allocation of the vehicle to the train is requested by the allocation execution request received from the operation management device 30 or the inspection management device 50. The vehicles that can be assigned to trains are extracted from the vehicles that have been inspected in the belt, and the vehicles that meet the constraints and equipment conditions and that can transport the required number of passengers are extracted from the extracted vehicles. Then, the vehicle data of the vehicle is stored in the vehicle allocation candidate data 114 (step 1006).

  As described above, the vehicle whose inspection is completed by the time of the train is assigned to the train from the inspection history and the inspection plan, so that the vehicle can be reliably allocated to the train consistent with the execution of the inspection. .

  Next, an operation flow of the influence determination unit 104 shown in FIG. 3 will be described.

  FIG. 11 is a diagram for explaining the operation flow of the influence determining unit 104 shown in FIG.

  The influence determination unit 104 first obtains the vehicle data stored in the vehicle allocation candidate data 114 by the vehicle candidate extraction unit 103 (Step 1101), and uses the plan creation device 40 for each candidate vehicle to accommodate the vehicle. Recalculation of a premises replacement plan, which is a plan related to this, is performed (step 1102). The yard replacement plan is an execution plan of an operation of moving a vehicle in the yard of a depot. More specifically, the vehicle information and the schedule information to be allocated are transmitted to the plan creation device 40, and the recalculated result is obtained. The plan creation device 40 performs recalculation so that the original plan is not changed as much as possible, that is, only the plan of the newly allocated vehicle can be added without changing the replacement plan of another vehicle. After obtaining the calculation result, the recalculated result is compared with the original plan to specify a changed portion (step 1103).

  Next, the impact determination unit 104 recalculates a crew assignment plan, which is a plan related to the assignment of crew members to trains (step 1104). The assignment plan of the staff is a work plan of the staff assigned to the train to be operated. At this time, recalculation is performed so that the original plan is not changed as much as possible, similarly to the campus replacement plan. After obtaining the calculation result, the recalculated result is compared with the original plan to specify a changed portion (step 1105).

  Next, the influence determination unit 104 acquires the inspection plan data managed by the inspection management apparatus 50, and specifies whether or not the work plan is recalculated with reference to the inspection plan data (step 1106). The work plan is a plan for performing inspection and cleaning work on the vehicle. These tasks are usually performed in the depot, before being assigned to the train. The influence determination unit 104 refers to the acquired inspection plan data, and transmits the vehicle information and the schedule information to be allocated to the candidate preparation vehicle to the plan creation device 40 when the inspection of the current day is allocated to the candidate vehicle and the inspection is not performed. The plan is recalculated (step 1107). After obtaining the calculation result from the plan creating device 40, the recalculated result is compared with the original plan to specify a changed portion (step 1108).

  Next, the impact determination unit 104 calculates the planned impact degree and the minimum preparation time from the contents of the change to the plan specified so far (step 1109). The degree of plan impact is an index indicating how much operation cost is required for a depot by changing various plans compared to before the change. For example, for each plan specified in steps 1103 and 1105, the content of the change is weighted by 1 point when changing the plan of another vehicle, 5 points when additional work occurs due to the plan change, and the like. Calculate and calculate the degree of impact of the plan change. Further, the minimum preparation time indicates the time required from the determination of the allocation as a result of the plan change to the use of the vehicle. The minimum preparation time is specified from the re-planned replacement plan. That is, in the case where the extracted candidate vehicle is assigned to the train, the influence determination unit 104 specifies changes that occur in each of the replacement plan, the crew plan, and the work plan, and manages the cost required for the specified change. It will be calculated as cost. As described above, the change that occurs in each of the replacement plan, the crew plan, and the work plan is specified, and the cost required for the change is calculated as the operation cost, so that the change can be objectively compared and the change is caused. Operation costs can be presented.

  In the calculation of the operation cost described above, for example, the cost required for changing the replacement plan is defined as the degree of influence on the replacement plan, and the cost required for newly assigning crew members and / or changing the assignment of crew members is applied to the crew plan. The impact and the cost of new work and / or change of work are calculated as the impact on the work plan. The impact on the replacement plan, the impact on the crew plan, and the impact on the work plan are calculated. It is conceivable to add the degrees to the operation cost.

  In this way, for the extracted candidates, the degree of influence on the replacement plan, the crew plan, and the work plan is calculated, and the influence on the replacement plan, the influence on the crew plan, and the work plan are calculated. By calculating the operation cost by summing up the degree of impact of the above, it is possible to present the operation cost in consideration of the influence on the replacement plan, the influence on the crew plan, and the influence on the work plan.

  If it is determined in step 1106 that an operation such as an inspection is not planned for the candidate vehicle, the processing in step 1109 is performed without performing the processing in steps 1107 and 1108.

  Thereafter, the influence determination unit 104 updates the vehicle allocation candidate data 114 based on the data specified in steps 1103, 1105, 1108, and 1109, and ends the processing (step 1110).

  Next, in the vehicle allocation support system shown in FIG. 1, including the exchange of data among the vehicle allocation support device 10, the demand management device 20, the operation management device 30, the plan creation device 40, the inspection management device 50, and the display device 60. The operation flow will be described.

  FIG. 12 illustrates data exchange between the vehicle allocation support device 10, the demand management device 20, the operation management device 30, the plan creation device 40, the inspection management device 50, and the display device 60 in the vehicle allocation support system illustrated in FIG. It is a figure for explaining the operation flow including.

  First, a request for executing vehicle allocation is transmitted from the operation management device 30 or the inspection management device 50 to the vehicle allocation support device 10 due to a diagram change or a test delay (step 1201).

  Upon receiving the allocation execution request, the vehicle allocation support device 10 acquires demand information from the demand management device 20 (step 1202) and acquires inspection information and inspection plan information from the inspection management device 50 (step 1203).

  The vehicle allocation support device 10 derives a vehicle allocation candidate based on the acquired information (step 1204).

  If it is necessary to change the depot plan as a result of deriving the vehicle allocation candidate, the vehicle allocation support device 10 requests the plan creation device 40 to re-plan (step 1205) and obtains the recalculated plan data. (Step 1206).

  Next, the vehicle allocation support device 10 transmits the specified vehicle data candidate to the display device 60 (Step 1207).

  After the vehicle data candidates transmitted from the vehicle allocation support device 10 are displayed on the display device 60, the user 80 who has confirmed the vehicle data candidates displayed on the display device 60 requests allocation vehicle determination or reallocation (step 1208).

  When the user 80 requests the reallocation of the vehicle, the vehicle allocation candidate deriving process in step 1204 is performed again (step 1209).

  On the other hand, when the user 80 has determined the assigned vehicle, the display device 60 notifies the determined vehicle assignment data to the vehicle assignment support device 10 (step 1210).

  When the vehicle to be allocated is determined, the vehicle allocation support device 10 notifies the operation management device 30 of the vehicle data of the vehicle to be allocated (step 1211), notifies the inspection management device 50 of the inspection plan data, and ends the processing.

  Hereinafter, a screen displayed on the display device 60 shown in FIG. 1 will be described.

  First, a vehicle facility selection screen when a user selects a vehicle to be allocated to a train will be described.

  FIG. 13 is a diagram showing an example of a vehicle facility selection screen displayed on the display device 60 shown in FIG.

  The display device 60 shown in FIG. 1 displays a vehicle facility selection screen that displays the vehicle allocation candidates derived by the vehicle allocation support device.

  As shown in FIG. 13, on the vehicle equipment selection screen displayed on the display device 60, the name of the train 1302 requested to be allocated, the equipment conditions 1303 required for the train, and the allocation candidates allocated to the train are displayed. The vehicle name 1310, the facility information 1311 of the allocation candidate vehicle with the vehicle name 1310, the excess number of rides 1304 in operation when the allocation candidate vehicle with the vehicle name 1310 is allocated to the train 1302, and the vehicle name 1310 When the allocation candidate vehicle is allocated to the train with the train name 1302, the shortest time 1305 until the train leaves the base from the main line and an allocation change button 1306 are displayed. In addition, as the minimum time 1305 before the vehicle leaves the main line from the base, for example, a time threshold (for example, 10 minutes) is set in advance. Further, the equipment information 1309 constituting the equipment condition 1303 indicates the equipment stored in the equipment condition data 112, and when it is desired to exclude the equipment from the vehicle conditions, the setting can be canceled by pressing an icon. In addition, when a vehicle condition is to be added, by pressing another equipment selection button 1312 constituting the equipment condition 1303, equipment not displayed in the equipment condition 1303 can be set as a condition. Note that, with respect to the equipment condition 1309, the equipment information 1311 of the candidate vehicle indicates the presence or absence of equipment by ““ ”,“ △ ”, and“ × ”, but the expression method uses a description using characters or other symbols. You may. Also, regarding the number of excess rides 1304 and the time 1305 that can be taken out of the base, if the item is registered in the equipment condition data 112 shown in FIG. can do. For example, it is conceivable to display a specific numerical value such as 5 hours in the time 1305 when the vehicle can be taken out of the base.

  On the vehicle facility selection screen 1301, the candidate vehicles are also ranked based on the degree of satisfaction of the facility conditions and the operation cost for vehicles other than the candidate vehicle with the highest priority. It is arranged and displayed. This display can be hidden by pressing the close button 1314. As described above, the candidate vehicles to be assigned to the trains are displayed in the order in which the satisfaction of the facility conditions and the operation cost are considered, so that the user can easily select a suitable candidate in consideration of the satisfaction of the facility conditions and the operation cost. It is possible to do. In this display, a maintenance influence confirmation button 1307 is displayed for each of the vehicles other than the candidate vehicle having the highest priority. When the maintenance influence confirmation button 1307 is pressed, a base influence detail screen 1308 is activated, and detailed information on the influence on the vehicle depot can be confirmed. The vehicle allocation examiner at the depot can select the number of vehicles that can be supplied on the screen and the presence or absence of facilities that have a demand for passengers while comparing the influence on the depot.

  When the user confirms the above contents and presses the assignment change button 1306, it is determined that the vehicle with the assigned vehicle name 1310 is assigned to the train with the train name 1302.

  Although the operation in the case where the user who refers to the screen is the vehicle allocation examiner at the depot has been described, when the operator who operates the vehicle and requests vehicle arrangement uses this system, the results of the other depots are combined. It is also possible to use such a method that the vehicle is displayed and the base for which the vehicle allocation is requested is also selected. In this case, by displaying the base name 1313 together, it is possible to determine which vehicle at which base can make a request for a vehicle arrangement based on this screen. If a business operator requests a vehicle arrangement and wants to use the vehicle immediately, the shortest time from the base to the main line is prioritized, even if the effect on the depot is large. If there is enough time to get out to the main line or if there is a slight change, arrange vehicles with less impact on the depot and give priority to vehicles with facilities that better meet passenger demand. It is also possible to make a request, for example.

  Next, the base management screen will be described.

  FIG. 14 is a diagram showing an example of the base management screen displayed on the display device 60 shown in FIG.

  The display device 60 shown in FIG. 1 displays the base management screen 1401 shown in FIG. The base management screen 1401 is a screen for making it easy to grasp the operating state of the base and the tendency of an index to be shared with the service provider. The base management screen 1401 displays the operation status 1402 for each route and the KPI graph 1403 managed by the vehicle base. indicate.

  The operation status 1402 for each route displays, in the form of a graph, a diagram of the operation status corresponding to the route name 14022 when the candidate is applied to the extracted candidates, and updates it appropriately in accordance with a change in the operation status. When the vehicle allocation request is notified, the screen is updated, and boldface or color is changed so as to distinguish any of the diamonds requesting the vehicle and displayed so as to be distinguished as the specific diamond 14021.

  The KPI graph 1403 of the depot shows, on the schedule when the candidate is applied, indexes to be shared with the service provider such as congestion rate and scheduled operation rate, and the depot of the depot such as operation cost, inspection achievement rate, and worker load. The indicators that the manager should understand and improve should be displayed in a graph.

  In this way, it is possible to graphically display the timetable after application and the index to be improved with respect to the extracted candidate vehicle, and favorably assist the user in evaluating the candidate.

  When the current time 14023 shown in the operation status 1402 for each route is changed, the KPI graph 1403 of the depot is displayed in the actual KPI for past times and the predicted KPI for past times. To update. Thereby, the user can visually recognize the index value and its change at each time and evaluate the candidate.

  The base management screen 1401 shown in FIG. 14 can be linked with the vehicle facility selection screen 1301 shown in FIG.

  In this case, pressing the vehicle facility selection screen linking button 14024 displayed on the base management screen 1401 causes the display device 60 to display the vehicle facility selection screen 1301. Thus, the display device 60 displays the condition of the item included in the facility condition so that the condition can be specified and changed. When a candidate vehicle whose KPI is to be checked on the KPI graph 1403 of the base management screen 1401 is selected on the vehicle facility selection screen 1301 displayed on the display device 60, the KPI graph 1403 of the base management screen changes the predicted change. The display is updated according to the data, and the KPI difference 1401 before and after the assignment is displayed. In the example shown in FIG. 14, the congestion rate 14026 before the vehicle is allocated is 85%, but the congestion rate 14026 after the vehicle is allocated is 80%, and one of the effects of the vehicle allocation is the 5% congestion rate. Can be reduced. When a vehicle allocation occurs while managing the KPI of the base, the user 80 checks the change rate of the KPI graph 1403 together, and uses the vehicle equipment selection screen 1301 to check the items included in the equipment conditions. Conditions can be specified or changed, and better vehicle allocation can be performed. Then, when the condition of an item included in the equipment condition is designated or changed using the vehicle equipment selection screen 1301, the display device 60 causes the vehicle candidate extraction unit 103 to extract a candidate based on the new equipment condition, For the extracted candidate, a diagram when the candidate is applied and a KPI when the candidate is applied are displayed. This allows the user to check the schedules and indices of the candidates while specifying or changing the equipment conditions, and evaluate the candidates.

  By performing the above-described series of processing, when the vehicle allocation is required, the user can determine what equipment the vehicle allocation candidate has and whether the equipment is suitable for the requested schedule. it can. In addition to confirming passenger satisfaction, it is possible to determine the vehicle allocation based on how much the operation costs and effects of the vehicle allocation are affecting the base, so the vehicle allocation man-hours are reduced. can do. That is, a search is made for a candidate of a vehicle that can be assigned to a train on a train schedule so as to satisfy the constraint conditions and equipment conditions, and to be able to transport passengers of the required number of passengers, and to calculate an operation cost required to assign the vehicle. , The vehicle candidates and the operating costs are displayed, so that the restrictions imposed on the vehicle allocation defined for each depot, the equipment that the vehicles must have for each time and / or route, and the transportation by train This makes it possible to assist in allocating vehicles in consideration of the number of passengers to be made possible and the cost required for vehicle operation.

  Further, in the above-described embodiment, an example was described in which a user who performs vehicle allocation at the vehicle depot uses the present system. However, the present device manages train operation, determines a schedule change, and sends the vehicle to the base. It may be used by the user of the service provider requesting the assignment. In this case, the screens shown in FIGS. 13 and 14 are displayed for the related bases, and are used to select a base to which a request is to be made, after grasping the load on the bases and the availability of vehicles that meet the demands of passengers. It is also possible.
