Summary of the Invention
Problems to be Solved by the Invention
[0004] Conventionally, for inventory management of consumable parts, during slack periods such as after a regular inspection, an operator checks the inventory quantity of consumable parts remaining at the work site or in the warehouse, and identifies and arranges the quantity of consumable parts required for the next regular inspection. Checking the inventory quantity of consumable parts is a task that takes a long time, such as several months, and places a burden on the operator.
[0005] Also, when arranging consumable parts for the next regular inspection, a spare quantity may be added to the planned usage quantity in the regular inspection based on past experience, and more may be arranged (ordered) than the actual usage quantity. For this reason, the inventory quantity of consumable parts may become excessive.
[0006] An object of this disclosure is to provide a management method and a management system that can appropriately manage the arranged quantity of consumable parts so that the inventory quantity of consumable parts, which consists of arranged parts used during a regular inspection and spare parts stored for backup, does not become excessive.
Means for Solving the Problems
[0007] According to one aspect of the present disclosure, the management method is a method for managing consumable parts consisting of procured parts, which are ordered in the required quantity each time the equipment is inspected periodically, and spare parts, which are kept in a certain number of spares separately from the procured parts, comprising the steps of: recording the total number of procured parts and spare parts when receiving the procured parts that were ordered before the periodic inspection; and ordering the procured parts and spare parts in the quantity that was reduced from the total quantity at the time of the periodic inspection.
[0008] According to one aspect of the present disclosure, the management system is a management system for managing consumable parts consisting of procured parts, which are ordered in the required quantity each time the equipment is inspected periodically, and spare parts, which are kept in a fixed number of separate spare parts, and comprises a recording processing unit that records the total number of procured parts and spare parts when receiving the procured parts that were ordered before the periodic inspection, and an ordering processing unit that orders the procured parts and spare parts in quantities that have decreased from the total number during the periodic inspection. [Effects of the Invention]
[0009] According to the above embodiment, the number of consumable parts ordered can be properly managed so that the inventory of consumable parts, consisting of parts ordered for use during periodic inspections and spare parts kept for backup, does not become excessive.

MODE FOR CARRYING OUT THE INVENTION
[0011] Hereinafter, embodiments will be described in detail with reference to the drawings. The management system 1 according to the present embodiment is a system for managing the inventory quantity and arrangement (ordering) of a plurality of consumable parts used for regular inspections of facilities such as power plants and factories.
[0012] (Overall configuration of the management system) FIG. 1 is a diagram showing the overall configuration of a management system according to an embodiment. As shown in FIG. 1, the management system 1 includes a terminal device 10 and a management server 20.
[0013] The terminal device 10 is used by an operator who manages the consumable parts P at a work site where equipment is installed to read an identification tag 30 attached to a case of the consumable parts P (such as a box or bag for transportation or storage) or a storage location (a shelf in a warehouse). The identification tag 30 is, for example, a shipping label printed with a two-dimensional code such as a QR code (registered trademark). Information such as identification information (part name, part number, etc.) and quantity of the consumable parts P is recorded on the identification tag 30. The terminal device 10 is a dedicated terminal (two-dimensional code scanner) capable of reading a two-dimensional code, a smartphone, a tablet, or the like.
[0014] The consumable parts P consist of ordered parts P1 for which the required quantity is ordered each time for regular inspection, and spare parts P2 for which a certain reserve quantity is stored separately from the ordered parts P1.
[0015] The management server 20 is communicably connected to the terminal device 10 and manages part information D1 including information such as the stock quantity and storage location of each consumable part P. In addition, the management server 20 orders the ordered parts P1 so that the ordered parts P1 for the planned usage quantity until the next regular inspection are received at the work site. Furthermore, when the spare parts P2 are used, the management server 20 promptly orders the shortage of the spare parts P2.
[0016] (Functional configuration of the terminal device) FIG. 2 is a diagram showing the functional configuration of the terminal device according to an embodiment. As shown in FIG. 2, the terminal device 10 includes a processor 11, a memory 12, a storage 13, a communication interface 14, a reading device 15, a display device 16, and an input device 17.
[0017] The memory 12 has a memory area necessary for the operation of the processor 11.
[0018] The storage 13 is a so-called auxiliary storage device, such as an HDD (Hard Disk Drive), an SSD (Solid State Drive), or the like.
[0019] The communication interface 14 is an interface for sending and receiving various types of information with an external device (management server 20).
[0020] The reading device 15 is a device such as a camera that reads the identification tag 30.
[0021] The display device 16 is a liquid crystal display or similar device that displays information read from the identification tag 30.
[0022] The input device 17 is a device for receiving operations from the operator. In this embodiment, the display device 16 and the input device 17 are assumed to be integrated by a touch panel. In other embodiments, the input device 17 may be an input device such as a keyboard provided separately from the display device 16.
[0023] The processor 11 performs its functions as an information acquisition unit 110 and a transmission processing unit 111 by operating according to a predetermined program.
[0024] The information acquisition unit 110 acquires information about consumable parts P from the identification tag 30 via the reader 15. The identification tag 30 records the quantity of consumable parts P (ordered parts P1 or spare parts P2) entering the work site, as well as a URL for accessing the part information D1 of the consumable parts P. For example, when receiving consumable parts P, the information acquisition unit 110 automatically acquires the identification information read from the identification tag 30 and the quantity of consumable parts P (number of items received).
[0025] Furthermore, the information acquisition unit 110 acquires information about consumable parts P that is entered by the worker via the input device 17. For example, when receiving consumable parts P, the information acquisition unit 110 acquires information about the storage location of consumable parts P (such as the warehouse shelf number) that is entered by the worker.
[0026] The transmission processing unit 111 transmits information about the consumable parts P acquired by the information acquisition unit 110 to the management server 20. For example, when receiving consumable parts P, the transmission processing unit 111 transmits information read from the identification tag 30 (identification information, quantity received, etc.) and information entered by the worker (storage location, etc.) to the management server 20. This information is recorded in the parts information D1 of the management server 20.
[0027] (Management server functional configuration) Figure 3 shows the functional configuration of a management server according to one embodiment. As shown in Figure 3, the management server 20 includes a processor 21, memory 22, storage 23, and a communication interface 24.
[0028] Memory 22 has a memory area necessary for the operation of the processor 21.
[0029] Storage 23 is a so-called auxiliary storage device, such as an HDD (Hard Disk Drive) or SSD (Solid State Drive). Part information D1 of consumable parts P is recorded in storage 23.
[0030] The communication interface 24 is an interface for sending and receiving various types of information with an external device (terminal device 10).
[0031] The processor 21 performs the functions of a recording processing unit 210 and an order processing unit 211 by operating according to a predetermined program.
[0032] When the recording processing unit 210 receives the ordered parts P1 and the spare parts P2 that were ordered before the periodic inspection, it records the total number of ordered parts P1 and spare parts P2 in the parts information D1.
[0033] The ordering processing unit 211 orders the required parts P1 and spare parts P2 in quantities that have decreased from the total quantity during the periodic inspection.
[0034] (Example of part information) Figure 4 shows an example of part information according to one embodiment. As shown in Figure 4, the parts information D1 includes identification information for each consumable part P, the number of parts to be used during periodic inspection, the surplus from the previous inspection, the number to be needed next time, the number in stock, and the storage location.
[0035] The identification information includes the part name and part number of the consumable part P.
[0036] The number of items to be used during periodic inspections is the maximum number of consumable parts P to be used (replaced) during the periodic inspection. Furthermore, periodic inspections may consist of multiple different inspections A, B, and C, performed in a predetermined order. For example, inspection A might involve inspecting some equipment (replacing consumable parts P). Inspection B might involve inspecting equipment different from that in inspection A. Inspection C might involve inspecting all equipment.
[0037] The previous surplus number represents the number of procured parts P1 that were not used (leftover) during the previous periodic inspection.
[0038] The next required quantity is the number of parts P1 that should be ordered for the next scheduled inspection.
[0039] The inventory count is the total number of procured parts P1 and spare parts P2 stored at the work site.
[0040] The storage location is the storage location for consumable part P (such as the shelf number in the warehouse).
[0041] (Processing of receiving ordered parts) Figure 5 shows an example of the receiving process for procured parts according to one embodiment. Here, we will explain the process of receiving the ordered part P1, referring to Figure 5.
[0042] First, the worker receives the ordered parts P1 that were ordered before the periodic inspection. The case of the ordered parts P1 has an identification tag 30 attached to it, which has been pre-recorded by the supplier of the ordered parts P1, including the identification information and quantity (number of items received). For example, the worker puts the terminal device 10 into receiving mode and performs an operation to read the identification tag 30. Then, the information acquisition unit 110 of the terminal device 10 acquires the identification information and the number of items received for the ordered parts P1 from the identification tag 30 (step S10).
[0043] Figure 6 is a first diagram illustrating the functions of a terminal device according to one embodiment. As shown in Figure 6, the display device 16 of the terminal device 10 displays the identification information and quantity of the ordered part P1 read by the information acquisition unit 110, as well as the registration button 160A and the cancel button 160B. When the operator presses the registration button 160A, the transmission processing unit 111 of the terminal device 10 sends the registration request for the quantity of ordered part P1, along with the identification information and quantity of the ordered part P1, to the management server 20 (step S11). If the operator presses the cancel button 160B, the terminal device 10 returns to step S10.
[0044] In other embodiments, the transmission processing unit 111 of the terminal device 10 may be configured to automatically send a registration request to the management server 20 when the information acquisition unit 110 acquires the number of incoming items. This can also simplify the operator's work.
[0045] Next, when the recording processing unit 210 of the management server 20 receives a registration request for ordered parts P1 from the terminal device 10, it records the total number of consumable parts P (ordered parts P1 and spare parts P2) stored at the work site and the newly received ordered parts P1 in the parts information D1 (Figure 4) (step S12). For example, the recording processing unit 210 extracts a record associated with the identification information of the ordered parts P1 for which registration has been requested from the parts information D1 recorded in the storage 23. The recording processing unit 210 updates the inventory count (the current total number of ordered parts P1 and spare parts P2) recorded in the extracted record by adding the number of ordered parts P1 received from the terminal device 10.
[0046] Figure 7 is a second diagram illustrating the functions of a terminal device according to one embodiment. Furthermore, the terminal device 10 may also accept input from the worker regarding the storage location of the ordered part P1. For example, the worker operates the terminal device 10 to enter a mode for referencing and updating part information D1. The information acquisition unit 110 of the terminal device 10 then reads the part information D1 recorded in the management server 20 and displays it on the display device 16. The information acquisition unit 110 also uses the identification information manually entered by the worker into the input device 17, or the identification information read from the identification tag 30, as a search key to search for the record of the ordered part P1 in the part information D1 and displays it on the display device 16. Additionally, when the worker registers the storage location of the ordered part P1, a screen for inputting the storage location is displayed on the display device 16 of the terminal device 10, as shown in the example in Figure 7. When an operator enters storage location information (shelf number) in the storage location input field 161A and presses the registration button 161B, the transmission processing unit 111 of the terminal device 10 sends a request to register the storage location of the ordered part P1, along with the identification information and storage location information of the ordered part P1, to the management server 20 (step S13).
[0047] Then, the recording processing unit 210 of the management server 20 adds the storage location of the ordered part P1 to the part information D1 (Figure 4) and records it (step S13).
[0048] If the storage location for the ordered part P1 has already been registered during a previous delivery and there is no need to change the storage location, steps S13 to S14 may be omitted.
[0049] Next, the worker places the received ordered part P1 into the storage location registered as the storage location (step S15). Note that the ordered part P1 and the spare part P2 may be stored in the same storage location, or they may be stored in different storage locations.
[0050] Each time the worker receives the ordered part P1 for each consumable part P, they perform the series of processes shown in Figure 5.
[0051] (Ordering process for procured parts) Figure 8 shows an example of the ordering process for procured parts according to one embodiment. Here, we will explain the ordering process for part P1, referring to Figure 8. Here, we will explain an example where, after performing inspection A, ordering is performed for part PA (Figure 4) for the next inspection B.
[0052] When using part PA in inspection A, the worker takes part PA from the storage area to the work floor (the place where inspection A is performed). At this time, the worker may take part PA to the work floor together with the case to which the identification tag 30 is attached. In addition, in this embodiment, the worker does not need to update part information D1 when taking out the ordered part P1.
[0053] After completing inspection A, the worker identifies the remaining quantities of procured part P1 and spare part P2 for part PA, as well as the number of procured part P1 used in inspection A. For example, the worker operates the terminal device 10 to enter a mode for referencing and updating part information D1. The information acquisition unit 110 of the terminal device 10 uses the identification information read from the identification tag 30 attached to the case of part PA (procured part P1) as a search key to search for the record of part PA in part information D1. The information acquisition unit 110 may also use the identification information manually entered by the worker into the input device 17 as a search key.
[0054] Figure 9 is a third diagram illustrating the functions of a terminal device according to one embodiment. As shown in Figure 9, the display device 16 of the terminal device 10 displays the identification information of the part PA retrieved by the information acquisition unit 110, its storage location, and the number of items in stock (total number of ordered part P1 and spare part P2). The display device 16 also displays a quantity input field 162A, an Apply button 162B, and a quantity setting button 162C.
[0055] First, the worker visually counts the current remaining number of parts PA. Alternatively, the worker may calculate the remaining number based on the weight of the parts PA. Next, the worker subtracts the current remaining number of parts PA from the inventory number of parts PA displayed on the display device 16 to determine the number of ordered parts P1 used for parts PA in inspection A. Then, the information acquisition unit 110 of the terminal device 10 receives the input operation from the worker and acquires the number of ordered parts P1 used for parts PA (step S20).
[0056] The quantity input field 162A in Figure 9 accepts direct input of a numerical value (the number of procured parts P1 to be used) by the worker. The entered numerical value is displayed in the quantity input field 162A. When entering the number of procured parts P1 to be used, a negative value (the number to be subtracted from the inventory quantity) should be entered. The quantity setting button 162C adds or subtracts the numerical value corresponding to the selected button.
[0057] The quantity setting button 162C has buttons such as "-10", "-", "+", "+10", and "Planned Quantity Used". When an operator enters the number of ordered parts P1 to be used, they press "-10", "-", and "Planned Quantity Used". Each time "-10" is pressed, the display in the quantity input field 162A (initial value is 0) is decreased by 10. Also, each time "-" is pressed, the display in the quantity input field 162A is decreased by 1. If the operator has used all of the ordered parts P1 in inspection A, they may also press "Planned Quantity Used". In this case, the value obtained by subtracting the planned number of ordered parts P1 to be used in inspection A (in the example in Figure 4, "-5") will be displayed in the quantity input field 162A.
[0058] The Apply button 162B is used to confirm the number of ordered parts P1 used. When the Apply button 162B is pressed, the information acquisition unit 110 of the terminal device 10 acquires the number displayed in the quantity input field 162A as the number of ordered parts P1 used for part PA in inspection A. The transmission processing unit 111 of the terminal device 10 also sends a request to update the total number, along with the identification information and number of parts PA used, to the management server 20 (step S21).
[0059] Furthermore, the worker places any surplus ordered parts P1 into the parts PA case and stores it on a shelf in the designated storage area (step S22). At this time, the worker can easily identify the storage location of the parts PA by referring to the screen display of the terminal device 10 shown in Figure 9.
[0060] Next, when the recording processing unit 210 of the management server 20 receives an update request for the total number of parts PA from the terminal device 10, it records and updates the part information D1 as the new inventory number (the total number of ordered parts P1 and spare parts P2 of part PA) by subtracting the number used from the inventory number of parts PA (step S23).
[0061] Furthermore, the order processing unit 211 of the management server 20 determines the order quantity of the ordered parts P1 for the next inspection B based on the number of ordered parts P1 for the parts PA received from the terminal device 10, or the number of parts PA in stock after updating. First, the order processing unit 211 determines whether or not there is a surplus of the ordered parts P1 for the parts PA (step S24).
[0062] For example, the ordering processing unit 211 determines that there is a surplus of ordered part P1 if the planned number of inspection A parts PA to be used is greater than the actual number used (step S24; YES). Alternatively, the ordering processing unit 211 may determine that there is a surplus of ordered part P1 if the updated inventory quantity of part PA is greater than the requested number of spare parts P2 for part PA. In this case, the ordering processing unit 211 records the surplus quantity of part PA in the "Previous Surplus Quantity" column of part PA in part information D1.
[0063] Furthermore, if there is a surplus of ordered parts P1, the ordering processing unit 211 determines the required number for the next inspection B by subtracting the surplus number of ordered parts P1 for part PA from the planned number of parts PA to be used in the next inspection B (step S25). At this time, the ordering processing unit 211 records the required number in the "Next Required Quantity" column for part PA in part information D1. In the example in Figure 4, the surplus number in inspection A is "3", and the number to be used in the next inspection B is "5". Therefore, the required number of ordered parts P1 for part PA in the next inspection B is "2".
[0064] On the other hand, if in inspection A all of the ordered parts P1 of part PA have been used and there is no surplus (step S24; NO), the ordering processing unit 211 determines the number of parts PA to be used in the next inspection B as the required number for the next inspection B (step S26).
[0065] Next, the ordering processing unit 211 processes the order for the required number of parts P1 determined in step S24 or step S25 (step S27).
[0066] Similarly, the same series of processes shown in Figure 8 are performed for other consumable parts P (parts PB, PC, ...). This prevents excess inventory by reducing the ordered parts P1 for each consumable part P by the amount remaining after inspection A.
[0067] (Ordering spare parts) Figure 10 shows an example of the ordering process for spare parts according to one embodiment. Here, we will explain the ordering process for spare part P2, referring to Figure 10.
[0068] For example, suppose in inspection A, after all of the procured parts P1 of part PC have been used, more part PC is needed. In this case, the worker will issue (deposit) spare parts P2 of part PC (step S30).
[0069] Furthermore, the operator operates the terminal device 10 to enter a mode for referencing and updating part information D1. The information acquisition unit 110 of the terminal device 10 uses the identification information read from the identification tag 30 attached to the case of part PC (spare part P2) as a search key to search for the record of part PC in part information D1. The information acquisition unit 110 may also use the identification information manually entered by the operator into the input device 17 as a search key.
[0070] When the information acquisition unit 110 of the terminal device 10 searches for a record of a component PC, it displays a screen on the display device 16 similar to that in Figure 9. The display device 16 displays the identification information of the component PC found by the information acquisition unit 110, its storage location, and the number of items in stock (total number of ordered parts P1 and spare parts P2). The display device 16 also displays a quantity input field 162A, an Apply button 162B, and a quantity setting button 162C.
[0071] Next, the worker inputs into the terminal device 10 that all of the ordered parts P1 have been used. For example, the worker presses the "Planned number used" button on the quantity setting button 162C, and then presses the Apply button 162B. The information acquisition unit 110 of the terminal device 10 then acquires the number of ordered parts P1 used (step S31). In the example in Figure 4, the planned number of parts PC to be used in inspection A is "10", so the number used is "10". The transmission processing unit 111 of the terminal device 10 also sends a request to update the total number along with the identification information and number used of parts PC to the management server 20 (step S32). The processing in steps S31 to S32 is the same as in steps S20 to S21 in Figure 8.
[0072] Next, when the recording processing unit 210 of the management server 20 receives an update request for the total number of component PCs from the terminal device 10, it records and updates the component information D1 as the new inventory number (the total number of ordered component P1 and spare component P2 for the component PC) by subtracting the number used from the inventory number of component PCs (step S33). Note that the processing in step S33 is the same as the processing in step S23 in Figure 8.
[0073] When the part information D1 is updated, the inventory count of part PC displayed on the display device 16 of the terminal device 10 becomes the number of spare parts P2 for part PC. The operator presses the quantity setting button 162C to further input the number of spare parts P2 to be used, and then presses the Apply button 162B. At this point, the information acquisition unit 110 of the terminal device 10 acquires the number of spare parts P2 to be used (step S34). The transmission processing unit 111 of the terminal device 10 also sends a request to update the total count to the management server 20, along with the identification information of part PC and the number of spare parts P2 to be used (step S35).
[0074] Next, when the recording processing unit 210 of the management server 20 receives an update request for the total number of component PCs from the terminal device 10, it records and updates the component information D1 as the new inventory number (total number of procured component P1 and spare component P2 for component PCs) by subtracting the number of spare component P2s used from the inventory number of component PCs (step S36).
[0075] Furthermore, the order processing unit 211 of the management server 20 processes an order for the required number of spare parts P2 (step S37). The number of spare parts P2 needed is the number of spare parts P2 requested minus the current inventory.
[0076] (Receiving and processing of spare parts) Figure 11 shows an example of the receiving process for spare parts according to one embodiment. Here, referring to Figure 11, we will explain the process of receiving the spare part P2 of part PC that was ordered in step S37 of Figure 10.
[0077] The worker receives the spare parts P2 of component PC. The case of spare parts P2 has an identification tag 30 attached to it, which has been pre-recorded by the supplier of the spare parts P2 (component PC) with identification information, quantity (number of items received), etc. The worker puts the terminal device 10 into receiving mode and performs an operation to read the identification tag 30. The information acquisition unit 110 of the terminal device 10 then acquires the identification information and number of spare parts P2 from the identification tag 30 (step S40). The number of spare parts P2 read from the identification tag 30 is displayed on the display device 16 of the terminal device 10 (for example, the quantity input field 162A in Figure 9).
[0078] The information acquisition unit 110 of the terminal device 10 may also accept input operations from the worker and acquire the number of spare parts P2 received by the parts PC. In this case, the display device 16 of the terminal device 10 will display the screen shown in Figure 9. For example, the worker can directly input the number of received items into the quantity input field 162A. Alternatively, the worker can input the number of received items by operating the quantity setting button 162C. Each time the "+10" button on the quantity setting button 162C is pressed, the display in the quantity input field 162A (initial value is 0) is increased by 10. Also, each time the "+" button is pressed, the display in the quantity input field 162A is increased by 1.
[0079] Furthermore, when the operator presses the Apply button 162B, the transmission processing unit 111 of the terminal device 10 sends a request to update the total number, along with the identification information of the component PC and the number of spare parts P2 in stock (step S41).
[0080] Furthermore, the worker places the received spare parts P2 on a shelf in the designated storage area (step S42). At this time, the worker can easily identify the storage location of the parts PC by referring to the display device 16 of the terminal device 10 shown in Figure 9.
[0081] Next, when the recording processing unit 210 of the management server 20 receives an update request for the total number of component PCs from the terminal device 10, it records and updates the component information D1 with a new inventory number (the total number of procured component P1 and spare component P2 of component PA) obtained by adding the number of spare component P2s received to the inventory number of component PCs (step S43).
[0082] When spare parts P2 are used, the management system 1 performs the series of processes shown in Figures 10 to 11, thereby quickly replenishing any shortage of spare parts P2.
[0083] (Effect, Action) As described above, the method for managing consumable parts P according to this embodiment includes the steps of recording the total number of ordered parts P1 and spare parts P2 in parts information D1 when ordering and receiving ordered parts P1 before a periodic inspection, and ordering ordered parts P1 and spare parts P2 in the number that has decreased from the total number (the number used) during the periodic inspection.
[0084] In this way, the number of consumable parts P ordered can be properly managed so that the inventory of consumable parts P, which consists of parts P1 ordered for use during periodic inspections and spare parts P2 kept for backup, does not become excessive.
[0085] Furthermore, in the step of ordering the procured parts P1, if there is a surplus of procured parts P1 after the periodic inspection, an order is placed to ensure that the number of procured parts P1 that is equal to the number of procured parts P1 to be used in the next periodic inspection minus the surplus number of procured parts P1 is received by the next periodic inspection (S25, S27 in Figure 8).
[0086] This method helps to prevent over-ordering of the procured part P1.
[0087] Figure 12 is the first figure showing an example of the inventory quantity of consumable parts according to one embodiment. The change in inventory levels when a surplus of ordered part P1 occurs during a periodic inspection will be explained with reference to Figure 12. The bar graph in Figure 12 shows the actual change in inventory levels of ordered part P1 and spare part P2 for consumable part P (e.g., part PA). The line graph shows the change in the total number of part PA recorded in part information D1.
[0088] Prior to receiving the shipment, only spare part P2 is stored in the warehouse. Furthermore, the total number of parts PA recorded in part information D1 is equal to the number of spare parts P2.
[0089] When the procured part P1 of part PA is received, the actual inventory quantity of part PA becomes the sum of the received procured part P1 and the spare part P2. Furthermore, by executing the series of processes shown in Figure 5, the total number of part PAs recorded in part information D1 matches the actual inventory quantity of part PAs.
[0090] Furthermore, during a periodic inspection, the ordered part P1 of part PA is used (dispatched) in two separate instances, resulting in a decrease in the actual inventory quantity. In this embodiment, since part information D1 is not updated when ordered part P1 is dispatched, the total quantity recorded in part information D1 remains unchanged from the time of receipt.
[0091] When surplus procured parts P1 are placed on shelves (received) after a periodic inspection, the series of processes shown in Figure 8 are performed. At this time, the total number recorded in the parts information D1 matches the actual number of items in stock. Also, here, the required number of procured parts P1 (ordered quantity) is obtained by subtracting the surplus number of procured parts P1 from the number of procured parts P1 that are scheduled to be used in the next periodic inspection. Therefore, only the required number will be received at the next receiving. In this way, in the management method according to this embodiment, even if a surplus of procured parts P1 occurs during a periodic inspection, it is possible to prevent the number of parts PA in stock from exceeding the sum of the number scheduled to be used during the periodic inspection and the number of spare parts P2 requested (resulting in excess inventory).
[0092] Furthermore, in the step of ordering the procured parts P1, if there is no surplus of procured parts P1 after the periodic inspection, an order is placed to ensure that the same number of procured parts P1 as the number of procured parts P1 to be used in the next periodic inspection are received by the next periodic inspection (S26, S27 in Figure 8).
[0093] By doing so, we can ensure that all the necessary parts P1 are procured in order before the next scheduled inspection.
[0094] Figure 13 is a second figure showing an example of the inventory quantity of consumable parts according to one embodiment. The change in inventory when the ordered part P1 is exactly used up during a regular inspection will be explained with reference to Figure 13. The bar graph in Figure 13 shows the actual change in inventory quantities of ordered part P1 and spare part P2 for consumable parts P (e.g., part PA). The line graph shows the change in the total number of part PA recorded in part information D1.
[0095] In a periodic inspection, part PA is used (dispatched) in two separate instances, and part P1 is completely used up in the second dispatch. In this embodiment, since part information D1 is not updated when part P1 is dispatched, the total number recorded in part information D1 remains unchanged from the time of receipt.
[0096] When surplus procured parts P1 are put into storage (received) after a periodic inspection, the series of processes shown in Figure 8 are performed. At this time, the total number recorded in the parts information D1 matches the actual inventory quantity. Also, since there is no surplus of procured parts P1 here, the required number of procured parts P1 (ordered quantity) will be the same as the number of procured parts P1 that are planned to be used in the next periodic inspection. Therefore, at the next receiving, the procured parts P1 for the planned number of uses will be received. Thus, in the management method according to this embodiment, even if all procured parts P1 are used up in a periodic inspection, an appropriate number of procured parts P1 can be ordered so that no shortage occurs in the next periodic inspection.
[0097] Furthermore, the consumable parts P management method according to this embodiment further includes a step of issuing spare parts P2 if there is a shortage of ordered parts P1 during a periodic inspection (step S30 in Figure 10). The step of ordering spare parts P2 involves ordering the same number of spare parts P2 as the number issued when spare parts P2 are issued (step S37 in Figure 10). The step of ordering ordered parts P1 involves ordering the same number of ordered parts P1 as the number of ordered parts P1 to be used in the next periodic inspection so that they arrive in stock by the next periodic inspection (steps S26 and S27 in Figure 8).
[0098] This allows for the prompt replenishment of spare part P2 if it is used during a regular inspection. Furthermore, it ensures that all required parts P1 are procured in sufficient quantities before the next regular inspection.
[0099] Figure 14 is a third figure showing an example of the inventory quantity of consumable parts according to one embodiment. The change in inventory when a procured part P1 is insufficient during a regular inspection and a spare part P2 is used will be explained with reference to Figure 14. The bar graph in Figure 14 shows the actual change in inventory quantities of procured part P1 and spare part P2 for consumable parts P (e.g., part PA). The line graph shows the change in the total number of part PA recorded in part information D1.
[0100] During a periodic inspection, part PA, specifically ordered part P1, is used (dispatched) in two separate instances. During the second dispatch, ordered part P1 becomes insufficient, and a portion of spare part P2 is used. In this embodiment, since part information D1 is not updated when ordered part P1 is dispatched, the total number recorded in part information D1 at the time of the first dispatch during the periodic inspection remains unchanged from the time of receipt. However, when spare part P2 is dispatched, the total number recorded in part information D1 is updated by executing the series of processes shown in Figure 10.
[0101] Furthermore, when spare parts P2 are issued, an order for the same number of spare parts P2 that were used (issued) is promptly placed (step S37 in Figure 10). Therefore, in the example in Figure 14, the receiving and storage of spare parts P2 takes place before the receiving of the next shipment for periodic inspection. This prevents the period during which spare parts P2 are insufficient from becoming prolonged. This prevents delays in equipment recovery due to a shortage of spare parts P2, for example, when a part PA needs to be replaced due to a sudden equipment failure.
[0102] Furthermore, an identification tag 30 is attached to the case of the ordered parts P1 to be received, which records the number of ordered parts P1 (number of items received). In the step of recording the total number, the total number obtained by adding the number of ordered parts P1 read from the identification tag 30 and the number of ordered parts P1 and spare parts P2 in stock recorded in the parts information D1 is stored.
[0103] This allows for the automation of inputting the number of incoming parts P1. This reduces the workload on workers in inventory management of consumable parts P.
[0104] Furthermore, after receiving the goods, the identification tag 30 is attached to the case of the ordered part P1 or to the storage location (shelf) of the ordered part P1. In the step of ordering the ordered part P1, the number of ordered part P1 to be used or the number of surplus is determined by subtracting the number of consumable parts P after periodic inspection from the total number read from the identification tag 30.
[0105] This makes it easy to identify the number of parts P1 used or surplus after a periodic inspection. This reduces the workload on workers in managing the inventory of consumable parts P.
[0106] Furthermore, the storage location of consumable parts P (ordered part P1 and spare part P2) may also be recorded in part information D1.
[0107] The variety of consumable parts P used in periodic inspections is enormous, and it can be difficult to keep track of where they are stored in a large storage area (warehouse). This can lead to delays in locating and retrieving necessary parts from the warehouse when needed for periodic inspections. However, in this embodiment, by pre-registering the storage location of each required part P1, workers can easily and quickly find out where the required parts P1 used in periodic inspections are stored.
[0108] As described above, several embodiments relating to this disclosure have been explained, but all of these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be carried out in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their variations are included in the scope and spirit of the invention, as well as in the claims and their equivalents.
[0109] For example, in the above embodiment, an example was described in which, in the ordering process of the procured part P1, the terminal device 10 sends the number of procured parts P1 used to the management server 20 and requests an update of the total number, but it is not limited to this. In other embodiments, instead of the number of procured parts P1 used, the terminal device 10 may accept input of the current remaining number of consumable parts P and send the update request of the total number to the management server 20 along with the current remaining number (steps S20 to S21 in Figure 8).
[0110] Furthermore, although the above embodiment describes an example in which the part information D1 is not updated when the ordered part P1 is issued, the embodiment is not limited to this. In other embodiments, steps S31 to S33 in Figure 10 may be executed each time the ordered part P1 is issued, and the total number of ordered parts P1 and spare parts P2 recorded in the part information D1 may be updated to always match the actual inventory quantity. In this way, the actual inventory quantity is always reflected in the part information D1, making it possible to manage the inventory of consumable parts P more precisely.
[0111] <Note> The above-described embodiment can be understood, for example, as follows:
[0112] (1) According to the first embodiment, the management method is a method for managing consumable parts P consisting of procured parts P1 which are ordered in the required quantity each time the equipment is inspected periodically, and spare parts P2 which are kept in a certain number of spares separately from procured parts P1, and includes the steps of recording the total number of procured parts P1 and spare parts P2 when receiving the procured parts P1 that were ordered before the periodic inspection, and ordering procured parts P1 and spare parts P2 in the number that was reduced from the total number during the periodic inspection.
[0113] In this way, the number of consumable parts P ordered can be properly managed so that the inventory of consumable parts P, which consists of parts P1 ordered for use during periodic inspections and spare parts P2 kept for backup, does not become excessive.
[0114] (2) According to the second aspect, in the management method relating to the first aspect, the step of ordering the procured parts P1 and spare parts P2 is as follows: If there is a surplus of procured parts P1 after the periodic inspection, the order is placed so that the number of procured parts P1 obtained by subtracting the surplus from the number of parts to be used in the next periodic inspection will be received by the next periodic inspection.
[0115] This method helps to prevent over-ordering of the procured part P1.
[0116] (3) According to the third aspect, in the management method relating to the first or second aspect, the step of ordering the procured parts P1 and spare parts P2 is to order the same number of procured parts P1 as the number to be used in the next procured inspection so that they are received by the next procured inspection, if there is no surplus of procured parts P1 after the procured inspection.
[0117] By doing so, we can ensure that all the necessary parts P1 are procured in order before the next scheduled inspection.
[0118] (4) According to the fourth aspect, the management method relating to any one of the first to third aspects further includes a step of issuing spare parts P2 when there is a shortage of ordered parts P1 during a periodic inspection, the step of ordering ordered parts P1 and spare parts P2 includes ordering the same number of spare parts P2 as the number issued when spare parts P2 are issued, ordering the same number of ordered parts P1 as the number to be used in the next periodic inspection so that they are received by the next periodic inspection, and the step of recording the total number includes recording the total number of ordered parts P1 and spare parts P2 when receiving the spare parts P2.
[0119] This allows for the prompt replenishment of spare part P2 if it is used during a regular inspection. Furthermore, it ensures that all required parts P1 are procured in sufficient quantities before the next regular inspection.
[0120] (5) According to the fifth embodiment, in the management method relating to any one of the first to fourth embodiments, an identification tag 30 for recording the number of ordered parts P1 is attached to the case of the ordered parts P1 to be received, and the step of recording the total number stores the total number obtained by adding the number of ordered parts P1 read from the identification tag 30 and the inventory numbers of ordered parts P1 and spare parts P2.
[0121] This allows for the automation of inputting the number of incoming parts P1. This reduces the workload on workers in inventory management of consumable parts P.
[0122] (6) According to the sixth embodiment, in the management method relating to the fifth embodiment, after receiving the goods, the identification tag 30 is attached to the case of the ordered parts P1 or the storage location of the ordered parts P1, and in the step of ordering the ordered parts P1 and spare parts P2, the number of ordered parts P1 to be used or the number of surplus is determined by subtracting the number of consumable parts P after periodic inspection from the total number read from the identification tag 30.
[0123] This makes it easy to identify the number of parts P1 used or surplus after a periodic inspection. This reduces the workload on workers in managing the inventory of consumable parts P.
[0124] (7) According to the seventh aspect, the management system 1 is a management system 1 for managing consumable parts P, which consists of procured parts P1 that are ordered in the required quantity each time the equipment is inspected periodically, and spare parts P2 that are always kept in a fixed number separate from the procured parts P1, and includes a recording processing unit 210 that records the total number of procured parts P1 and spare parts P2 when receiving procured parts P1 that were ordered before the periodic inspection, and an ordering processing unit 211 that orders procured parts P1 and spare parts P2 in quantities that have decreased from the total number during the periodic inspection.
