Description

The present invention relates to a system that supports vehicle allocation.
In particular, this is a vehicle allocation support system that takes into consideration the inspection implementation status and vehicle operation section on the day.

  The vehicle allocation in the railway is based on the normal vehicle operation plan, which vehicle is allocated at the vehicle base. However, this vehicle allocation is planned several days before, and if there is no change, the vehicle allocation is performed according to the plan. However, when the schedule is disturbed, the vehicle operation is changed and the number of usable vehicles is also reduced. Therefore, a system for efficiently allocating vehicles at the time of schedule disturbance on the day becomes important. Patent document 1 is mentioned as a technique relevant to this. In patent document 1, the system which transmits the condition of the inspection on the day from a vehicle base to a central command center is disclosed.

JP-A-9-226588

  However, in Patent Document 1, since the accuracy with respect to the inspection end time on the day is not high, there arises a problem that the vehicle cannot be allocated without completing the inspection of the vehicle at the expected time. In addition, since only real-time status is taken into account, even if it is determined that it can be used at the central command office, there is a high possibility of affecting the operation of the next day.

  Therefore, in the present invention, in order to increase the accuracy of the inspection end time, the inspection end time with higher accuracy is predicted by considering the inspection difficulty level, the inspection results, and the person in charge of inspection. In addition, considering the operation and inspection type of the next day as a system, even if the vehicle is used suddenly on the day, it is possible to narrow down the vehicles that can be used together with reducing vehicle operation disturbance to the next day.

  According to the present invention, it is possible to determine the inspection end time with high accuracy. Moreover, by considering the operation after the next day, the disturbance after the next day is reduced, and the vehicle operation on that day becomes smooth.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows an example of a system configuration of a vehicle allocation support system. This system can be executed by using the terminal 101, the vehicle search server 102, various databases (103 to 108), the inspection result server 109, the network 110, and the portable terminal 111. Here, the processing unit (CPU) of the vehicle search server is a function of the vehicle assignment availability determination process, unassigned vehicle extraction process, priority determination process with next-day operation, vehicle inspection process during inspection, and inspection end probability determination process. Execute.

  Next, the overall processing flow will be described. First, the process of reflecting the inspection status in real time will be described. Inspection results (inspection date, vehicle ID, inspection ID, inspection ID branch number, inspection item, person in charge information) are transmitted from the portable terminal 111 to the inspection result server 109 via the transmission path 110. After sending data to the inspection result server 109, the inspection result (inspection ID, vehicle ID, inspection item ID, inspection branch number ID, inspection item, inspection end time, inspection date, person in charge information) data is transferred to the inspection result table 105. Store it. As described above, real-time inspection data can be stored in the inspection result table 105. Next, a case where a diamond disturbance occurs will be described. First, a connection is made from the terminal 001 to the vehicle search server 102 via the transmission path 110. Vehicle information (information such as vehicle type, system, vehicle ID, etc.) required for processing in each server, vehicle allocation information (vehicle allocation information for the current day and the next day), inspection plan information (inspection date, vehicle ID, inspection ID, Information such as examination name) is collected from each table. Next, we will look at the processing in detail. First, real-time processing will be described. Reflect and store the inspection results (inspection ID, vehicle ID, inspection item ID, inspection branch ID, inspection item, inspection end time, inspection date, person in charge information) in the inspection result table 105 in real time from the inspection result server 109 . Next, daily batch processing will be described. The vehicle allocation information and vehicle inspection plan information for the current day are tabulated by daily batch processing. As processing, vehicle information table 106 (vehicle ID, model, format, vehicle number, organization ID, stop information), vehicle allocation table 107 (vehicle ID, same day operation ID, next day operation ID, next day operation ID), inspection plan table Merge data from 108 (inspection ID, inspection date, vehicle ID, inspection item ID, next day operation ID) and create vehicle inspection / assignment table 103 (vehicle ID, operation ID, inspection ID, rest information) for the day . By performing this process, it is possible to narrow down the vehicle allocation information for the current day in advance. Next is master data. The inspection item table 104 is assumed to be master data. The inspection item table (inspection item ID, inspection branch number ID, inspection name, inspection item, inspection difficulty) is configured to register data when a new vehicle is registered. The created data is called and used using SQL as necessary when processing is performed by the vehicle search server. The process will be described with reference to FIG.

  Here, the tables used in the flowcharts of FIGS. 2 to 6 will be described. FIG. 9 to FIG. 14 show tables that are inputs of this system.

  FIG. 9 is a table storing basic vehicle information. It becomes the input of this system.

  FIG. 10 is a table storing the allocation status of vehicles. It becomes the input of this system.

  FIG. 11 is a table storing information relating to a vehicle inspection plan. It becomes the input of this system.

  FIG. 12 is a table storing vehicle inspection and allocation information for the current day. In this system, intermediate data is updated every day.

  FIG. 13 is a table storing vehicle inspection items and inspection difficulty levels. In this system, it becomes master data.

  FIG. 14 is a table storing the results of the inspection vehicle. It becomes the input of this system.

  Next, the processing of this system will be described using a flowchart.

  FIG. 2 shows a main process for performing vehicle allocation. This will be described with reference to the flowchart of FIG. First, unassigned vehicle extraction processing (S0001) is performed. Here, it is a process of extracting a vehicle that is not operated. As a retrieval method, the processing for extracting all null operation IDs from the current day inspection / allocation table of FIG. Details of this processing will be described with reference to FIG. Next, a stoppage determination process (S0002) is performed. The stoppage determination process is a process for determining a vehicle to which a vehicle cannot be assigned. A closed vehicle is a vehicle that cannot be assigned normally, such as a vehicle just before it is scrapped. If this determination is NG, the vehicle is not assigned (S0003), the vehicle is not assigned, and is written in the vehicle evaluation table of FIG. On the other hand, vehicles that are not at rest are OK, and the process proceeds to inspection type determination (S0004). The inspection type determination is a process for determining the type of inspection in the railway. Railway inspections include cleaning, work inspection, police box inspection, critical part inspection, and general inspection. Of these inspections, the alternating inspection, the important part inspection, and the general inspection have many inspection items, and it takes an inspection time. In this process, the inspection is excluded from the vehicle allocation target (S0005) and is written in the vehicle evaluation table of FIG. On the other hand, other inspections and cleanings are subject to vehicle allocation because of the short inspection time. Therefore, in the case of work inspection and cleaning, the operation moves to the next day operation determination (S0006). The next day operation determination is a step of determining whether or not the corresponding vehicle is assigned to operation on the next day. When operation is assigned on the next day, it is necessary to move the vehicle to that location by the next day, which makes operation difficult. Therefore, if operation is allocated the next day, the vehicle operation allocation priority is set to -5 (S0007), and it is written in the vehicle evaluation table of FIG. The vehicle allocation priority is a numerical value of the vehicle allocation priority. The vehicle allocation priority is defined here as +10 for the highest and -8 for the lowest. Next, priority determination processing (S0008) is performed with the next day operation. Details will be described in the processing of FIG. Next, it is a process when there is no operation the next day. When there is no operation on the next day, there are few restrictions on the vehicle operation described above, and it is only necessary to return the vehicle to the previous day. Therefore, the vehicle allocation priority is not lowered. Next, a current status determination (S0009) is performed. The current status determination is a step of determining whether the vehicle is currently being inspected. If the vehicle is currently being inspected, it is determined that there is a limitation on vehicle allocation because the vehicle cannot be moved immediately. For a vehicle that is currently determined to be inspected, the in-inspection vehicle determination process (S0010) is performed. The vehicle determination process during inspection will be described with reference to the process of FIG. On the other hand, when the vehicle inspection is completed in the in-inspection vehicle determination process, the vehicle allocation priority is set to +10 (S0011), and the result is written in the vehicle evaluation table of FIG. It is determined that this vehicle has the highest priority.

  FIG. 3 is a process for extracting unassigned vehicles and vehicles that fall within a specific operation section. An unallocated vehicle refers to a vehicle that is not operated on that day. First, the operation side is entered on the command side (S0101). The operable section refers to a section that can be operated when a time disturbance occurs. For example, if there is an A station to a B station to a C station, and an inoperable section such as an accident occurs at the A station to the B station, the operable section is defined as the B station to the C station. Next, the relevant factory determination process (S0102) is performed. The relevant factory determination process is a process for extracting a vehicle factory in the operable section. The vehicle factory as used herein is defined as a vehicle that is stored and inspected. Next, the relevant factory is selected (S0103). The relevant factory selection is a step of selecting a factory for which the command is to be issued from the factories extracted in the relevant factory determination process. Finally, unallocated vehicle extraction processing (S0104). The unassigned vehicle extraction process is a process for extracting a vehicle that is not assigned to an operation in the factory selected by the factory selection. This is a process of extracting a vehicle when the operation ID is NULL in the vehicle inspection / assignment table 103 (vehicle ID, operation ID, inspection ID, rest information) for the day of FIG.

  FIG. 4 shows a priority determination process when there is a next day operation. The case where there is operation on the next day is processing when the operation allocation of the vehicle is performed after the next day. First, the next day operation start station selection (S0201) is performed at the terminal 001. The next day operation start station selection is a step of selecting and inputting the operation start station of the next day by a command. The operation start station is a reference station which station starts from the beginning of the day operation. From the above, it becomes possible to determine the operation start station of the next day. Next is start station determination processing (S0202). The start station determination process is a process for determining whether the station selected in the next day operation start station selection is the same station as the operation start station after the next day. If the next day operation start station does not match, it is excluded from the vehicle allocation target and is written in the vehicle evaluation table of FIG. If there is a match in the starting station determination, the current status determination (S0204) is performed. The current status determination is a step of determining whether the vehicle is currently being inspected. If it is determined that the vehicle is currently being inspected, a vehicle under inspection determination process (S0205) is performed. The vehicle determination process during inspection will be described with reference to the process of FIG. Next, the vehicle allocation priority is increased by +2 (S0206) and written to the vehicle evaluation table of FIG. This is a process for correcting the vehicle allocation priority. On the other hand, if the vehicle inspection is completed in the in-inspection vehicle determination process, the vehicle allocation priority is set to +5 (S0207), and the result is written in the vehicle evaluation table of FIG. This vehicle is determined as a vehicle having a high priority among vehicles in the case of operation on the next day.

  FIG. 5 shows steps for performing the vehicle determination process during inspection. First. The terminal 001 inputs the use start time and the vehicle base (S0301). In this process, it is possible to set restrictions on the system side by inputting the use start time and the vehicle base to be delivered. The use start time refers to the time at which the vehicle is to be released when a time disturbance or the like occurs. In addition, the vehicle base to be issued is a process of inputting which base vehicle to output. Next is time and place determination (S0302). The time and place determination is processing for determining the use start time and the contents input at the input of the vehicle base and the scheduled end time of inspection of the vehicle being inspected at the vehicle base. The scheduled inspection end time is the scheduled time when the vehicle inspection ends. The scheduled time when the inspection is completed is obtained by inputting from the portable terminal 007 by a person who inspects the vehicle. When the scheduled inspection time exceeds the time and place determination, the vehicle allocation priority is set to -10 (S0303), the vehicle allocation priority is lowered, and the result is written in the vehicle evaluation table of FIG. On the other hand, when the time and place determination does not exceed the scheduled inspection time, an inspection end probability determination process (S0304) is performed. The inspection end probability determination process is a process for determining from the inspection difficulty level whether or not the inspection is completed according to the scheduled inspection end time. Details of the inspection end probability determination process will be described with reference to FIG.

  FIG. 6 is a step for performing an inspection end probability determination process. In this step, it is determined whether or not the scheduled end time of inspection can be surely observed. First, the remaining inspection item difficulty level determination process (S0401) is performed. The remaining inspection item difficulty level determination process is a process of picking up the remaining inspection items and determining the number of inspections with a high degree of difficulty. The level of difficulty is set in advance, and the allocation priority of the vehicle is determined according to the level. The inspection difficulty level is set from 1 to 5. If inspections with difficulty levels of 4 and 5 are more than half of the entire inspection, the vehicle allocation priority is set to -5 (S0402), and is written in the vehicle evaluation table of FIG. In other cases, the vehicle allocation priority is set to +5 (S0403), and is written in the vehicle evaluation table of FIG. The vehicle allocation priority is determined as described above.

  FIG. 8 is a table summarizing the results of the processing performed in FIGS. First, the vehicle 1 indicates a closed vehicle. Since this vehicle is closed, it is judged as “NG” in the stop determination process, so that this vehicle is determined to be assigned. Next is the vehicle 2. This vehicle is the vehicle to which the police inspection is assigned. Although it is OK in the stoppage determination, it becomes NG in the inspection type determination, and is a harm to be assigned to the vehicle. Next is the vehicle 3. This vehicle is in operation when the next day is in operation and the starting station on the next day is NG. Since this vehicle is NG in the next day operation determination and NG in the start station determination, it is excluded from the vehicle allocation target and is written in the vehicle evaluation table of FIG. Next is the vehicle 4. This vehicle is in operation the next day, and the next day's starting station is OK and the vehicle has been inspected. The vehicle in this case can be used now, and since there is no problem in the next day's operation, the vehicle is assigned and the vehicle can be assigned. The vehicle allocation priority is determined to be +2. Next is the vehicle 5. This vehicle is in operation when the next day is in operation and the starting station of the next day is OK, and the vehicle has not been inspected. However, because it is NG in the time / place determination, it is excluded from the vehicle allocation target, and is written in the vehicle evaluation table of FIG. Next is the vehicle 6. This vehicle is in operation when the next day is in operation and the starting station of the next day is OK, and the inspection has not been completed. However, since there are few vehicles that have a high degree of difficulty for the remaining inspection, this vehicle is an assignment target because the accuracy of the inspection end is high. The allocation priority is +2. Next is the vehicle 7. This vehicle is in operation on the next day, and the inspection is not completed for the vehicle when the starting station of the next day is OK, and there are many remaining high difficulty inspections. Therefore, although vehicle allocation is targeted, the vehicle allocation priority is low and becomes -8. Next is the vehicle 8. This vehicle is not operated the next day, and the inspection is completed or is a standby vehicle. Therefore, the allocation priority of the vehicle is high and becomes +10. This vehicle is the vehicle that should be delivered with the highest priority. Next is the vehicle 9. This vehicle is not operated the next day, and has not been inspected. Also, because the time / location determination is NG, the vehicle is not assigned and is written in the vehicle evaluation table in FIG. Next is the vehicle 10. This vehicle is not operated the next day, and has not been inspected. Furthermore, since there are few things with high inspection difficulty and it is highly likely that the inspection will be completed on time, the vehicle allocation priority is +5. This vehicle is a vehicle that should be delivered prior to the vehicle 8. Next is the vehicle 11. This vehicle is not operated the next day, and has not been inspected. Furthermore, since there are many things with high inspection difficulty and it is unlikely that the inspection will be completed according to the time, the allocation priority of the vehicle is -5.
