Returning to FIG. 1, the explanation of the maintenance plan creation support system 1 will be continued. The processing unit 20 of the maintenance plan creation support system 1 includes an input processing unit 21, an information acquisition unit 22, a notification processing unit 23, a display processing unit 24, and an update processing unit 25.

The input processing unit 21 performs processing in response to operations on the input unit 42 by the manager U1 and processing in response to operations on the input unit 52 by the worker U2. When referring to the manager U1 and the worker U2 without distinguishing them individually, they may be referred to as users U.

For example, when an operation by user U on input units 42 and 52 is a login request, if the ID and password entered by the operation on input units 42 and 52 match a preset ID and password, the input processing unit 21 permits the login request of user U. In the following, user U whose login request has been permitted may be referred to as a login user.

When a login request is accepted by the input processing unit 21, the information acquisition unit 22 acquires the maintenance information 11, management information 12, and inventory information 13 from the memory unit 10.

The notification processing unit 23 determines, based on the management information 12 acquired by the information acquisition unit 22, whether the period until the production discontinuation is within a preset period and whether the production discontinuation period has passed.

The notification processing unit 23 notifies the logged-in user of information related to the production discontinuation time if the period until the production discontinuation time is within a preset period or if the production discontinuation time has passed. The information related to the production discontinuation time is, for example, information indicating that the production discontinuation time is approaching or information indicating that the production discontinuation time has passed.

In the following, the production stop time of the maintenance target may be referred to as the production stop time Ts, the current year and month as the current year and month Tn, and a preset period as the threshold period Tths. The notification processing unit 23 determines whether the period difference ΔTs between the production stop time Ts and the current year and month Tn is equal to or less than the threshold period Tths. If the period difference ΔTs is equal to or less than the threshold period Tths, the notification processing unit 23 notifies the logged-in user of information related to the production stop time Ts.

Figure 6 is a diagram showing an example of information related to the production discontinuation time notified by the notification processing unit according to the first embodiment. As shown in Figure 6, notification information 80, which is information related to the production discontinuation time Ts, includes "notification title", "category", "importance", "text", "sender", "expiration date and time", and "sent date and time".

"Notification title" is information that indicates an overview of the notification content, "category" is information that indicates the category of the notification content, "importance" is information that indicates the importance of the notification, and "text" is information that indicates the details of the notification content. "Sender" is information that indicates the notifier, "expiration date" is information that indicates the expiration date of the notification content, and "sent date and time" is information that indicates the date and time the notification was made.

The notification information 80 shown in FIG. 6 indicates that the system administrator of the maintenance plan creation support system 1 notified at 14:35 on February 1, 2020 that the production stop date Ts of the generator with equipment ID "E003" in facility AA is approaching.

Returning to FIG. 1, the processing unit 20 will be described further. The notification processing unit 23 of the processing unit 20 determines whether the period until the end of the warranty period is within a preset period and whether the warranty period has been exceeded, based on the management information 12 acquired by the information acquisition unit 22. If the period until the end of the warranty period is within the preset period or if the warranty period has been exceeded, the notification processing unit 23 notifies the logged-in user of information regarding the warranty period.

In the following, the end date of the warranty period is the warranty deadline Tw, the current date is the current date Tn, and the preset period is the threshold period Tthw. The notification processing unit 23 determines whether the period difference ΔTw between the warranty deadline Tw and the current date Tn is equal to or less than the threshold period Tthw. If the period difference ΔTw is equal to or less than the threshold period Tthw, the notification processing unit 23 notifies the logged-in user of information related to the warranty period. The information related to the warranty period is, for example, information indicating that the warranty period is approaching or information indicating that the warranty period has expired.

The notification processing unit 23 also determines the number of items to be replaced based on the maintenance information 11 and inventory information 13 acquired by the information acquisition unit 22, and if the value Ni obtained by subtracting the determined number of items to be replaced from the inventory quantity is equal to or less than the inventory threshold Na, notifies the logged-in user of information regarding the inventory of the items to be maintained. The information regarding the inventory includes, for example, information such as the inventory quantity and the number of items to be replaced.

For example, assume that the inventory information 13 is in the state shown in FIG. 5 and the planned replacement quantity for the part "generator bearing" is "2." In this case, the value Ni obtained by subtracting the planned replacement quantity from the inventory quantity is "9," which is below the inventory threshold Na of "10." Therefore, the notification processing unit 23 notifies the logged-in user of information regarding the inventory of the part "generator bearing."

Information is notified to the logged-in user by displaying the information on the logged-in user's display unit. For example, the logged-in user's display unit is display unit 43 when the logged-in user is administrator U1, and is display unit 53 when the logged-in user is worker U2.

When the logged-in user is the administrator U1, the display processing unit 24 displays a maintenance plan screen on the display unit 43, and when the logged-in user is the worker U2, the display processing unit 24 displays a maintenance work screen on the display unit 53. First, the maintenance plan screen displayed on the display unit 43 of the administrator U1 will be described.

The display processing unit 24 displays a maintenance plan table on the display unit 43 of the logged-in administrator U1 based on the maintenance information 11 and management information 12 acquired by the information acquisition unit 22. Figure 7 is a diagram showing an example of a maintenance plan screen including a maintenance plan table displayed on the display unit according to the first embodiment.

The maintenance plan screen 60 shown in FIG. 7 includes a maintenance plan table 61, an individual setting button 62, a repeat setting button 63, an automatic inspection record setting button 64, a production stop information registration button 65, a registration button 66, and a discontinued equipment display box 67. In the maintenance plan screen 60 shown in FIG. 7, different colors are indicated by different hatching.

The maintenance plan table 61 includes information for each maintenance object, such as the name of the maintenance object, the warranty period, the type of maintenance, the time Ts when production will be stopped, the time when maintenance will be performed, and the planned time when maintenance will be performed. The maintenance object is a device or a part. The name of the maintenance object is the name of the device or the name of the part, and in the maintenance plan table 61 shown in FIG. 7, it is, for example, "generator," "generator bearing," "shaft," or "air conditioner."

The warranty period is indicated in the maintenance plan table 61 shown in FIG. 7 by the end of the warranty period, for example, "December 2018" for generators, "April 2028" for generator bearings, "June 2025" for shafts, and "December 2022" for air conditioners.

In the maintenance planning table 61 shown in FIG. 7, the production cessation time Ts is indicated as the year or month when production cessation will begin. For example, for generators, it is "2028," for generator bearings, it is "2030," and for shafts and air conditioners, it is undecided.

The maintenance implementation timing is the time when maintenance work was performed on the maintenance target, and the planned maintenance timing is the time when maintenance work is planned to be performed on the maintenance target. The maintenance plan table 61 shown in FIG. 7 shows the maintenance implementation timing and planned maintenance timing for each maintenance type for the period from 2016 to 2030. In the maintenance plan table 61 shown in FIG. 7, the period from 2016 to 2030 is divided into unit periods in yearly units, and the maintenance implementation timing and planned maintenance timing on an annual basis are shown.

For example, in the example shown in FIG. 7, the time of inspection that has been performed is indicated by a white star mark, and the time of replacement that has been performed is indicated by a white diamond mark. This allows manager U1 to easily understand the time of maintenance work that has been performed. In addition, in the example shown in FIG. 7, inspections that have been performed and replacements that have been performed are represented as inspected and replaced.

In the example shown in FIG. 7, inspections that have not been performed by the scheduled time are indicated with a black star mark, and replacements that have not been performed by the scheduled time are indicated with a black diamond mark. This allows manager U1 to easily grasp maintenance work that has not been performed even after the scheduled time has passed. In the example shown in FIG. 7, inspections that have not been performed by the scheduled time and replacements that have not been performed by the scheduled time are represented as not inspected and not replaced.

In the example shown in FIG. 7, the scheduled inspection times are indicated with a colored star mark, and the scheduled replacement times are indicated with a colored diamond mark. This allows manager U1 to easily grasp the future scheduled times for maintenance work. In the example shown in FIG. 7, the scheduled inspection times and scheduled replacement times are represented as an inspection plan and a replacement plan.

In the example shown in FIG. 7, the frame of each unit period indicating the current year in the maintenance plan table 61 is colored with a first color. In this way, since the frame of each unit period indicating the current year is highlighted in the maintenance plan table 61, the manager U1 can easily grasp the position of the frame indicating the current year in the maintenance plan table 61.

In the example shown in FIG. 7, in each row for the replacement of each maintenance item in the maintenance plan table 61, the box for each unit period after the production discontinuation date is colored a second color, and the box for each unit period outside the warranty period is colored a third color.

In this way, in the maintenance plan table 61, the period after the production stop date and the period outside the warranty period are highlighted for each maintenance item, so that the manager U1 can easily understand the period after the production stop date and the period outside the warranty period in the maintenance plan table 61.

In addition, since the maintenance plan table 61 displays the period after the production stop date and the period outside the warranty period in a timeline, the manager U1 can easily understand the period after the production stop date and the period outside the warranty period in the maintenance plan table 61.

The display processing unit 24 can also highlight the frame of each unit period indicating the current year, the frame of each unit period after the production discontinuation date, and the frame of each unit period outside the warranty period in a display manner other than color. For example, the display processing unit 24 can highlight the frame of each unit period with a pattern or symbol instead of color.

The individual setting button 62 is a button for editing the planned timing of maintenance work in the maintenance plan table 61. When the individual setting button 62 is pressed, the input processing unit 21 individually accepts edits such as adding, deleting, or changing the planned timing of maintenance work in the maintenance plan table 61. The display processing unit 24 causes the display unit 43 to display the maintenance plan table 61 updated based on the edits accepted by the input processing unit 21.

Administrator U1 can operate input unit 42 to press individual setting button 62, and then operate input unit 42 to add, delete, or change colored star marks or colored diamond marks in maintenance plan table 61.

The repeat setting button 63 is a button for setting a periodic repeat time as the planned period for maintenance work. When the repeat setting button 63 is pressed and a row in the maintenance plan table 61 is selected by the administrator U1 operating the input unit 42, the input processing unit 21 accepts input of the start date and period of the maintenance work. The display processing unit 24 displays on the display unit 43 the maintenance plan table 61 that has been updated by repeatedly setting the timing of the maintenance work based on the start date and period of the maintenance work accepted by the input processing unit 21.

The automatic inspection record setting button 64 is a button for automatically adding the maintenance record of the equipment in the selected row, which is the selected row, to the maintenance plan table 61. When the input processing unit 21 accepts the pressing of the automatic inspection record setting button 64 and the selection of a row in the maintenance plan table 61, the information acquisition unit 22 acquires the maintenance work record for the equipment in the selected row from the history information 14.

The display processing unit 24 causes the display unit 43 to display the maintenance plan table 61 to which the maintenance results acquired by the information acquisition unit 22 have been added. For example, when the automatic inspection results setting button 64 is pressed and the rows for "generator" and "replacement" are selected in the maintenance plan table 61, the display processing unit 24 causes the display unit 43 to display the maintenance plan table 61 to which the generator replacement results have been added.

The production stop information registration button 65 is information for adding information on the production stop time Ts to the maintenance plan table 61. When the input processing unit 21 accepts the pressing of the production stop information registration button 65 and the input of information on the production stop time Ts, the update processing unit 25 adds the input information on the production stop time Ts to the management information 12 and updates the management information 12.

The information acquisition unit 22 acquires the information on the production stop time Ts that has been added to the management information 12 by the update processing unit 25. The display processing unit 24 displays the maintenance plan table 61 to which the information on the production stop time Ts acquired by the information acquisition unit 22 has been added on the display unit 43.

The registration button 66 is a button for reflecting the updated maintenance plan table 61 in the maintenance information 11. When the input processing unit 21 accepts the pressing of the registration button 66, the update processing unit 25 updates the maintenance information 11 and management information 12 based on the information of the updated portion of the maintenance plan table 61. This enables the display processing unit 24 to display the updated maintenance plan table 61 on the display unit 43 for the administrator U1 who logs in next.

The discontinued equipment display box 67 is a selection box for hiding information about equipment other than equipment whose production has been discontinued. When the input processing unit 21 receives the administrator U1's operation on the input unit 42 to press the discontinued equipment display box 67, the display processing unit 24 hides information about equipment other than equipment whose production has been discontinued.

When notifying the manager U1 of information regarding the inventory of the maintenance object, the notification processing unit 23 can add information regarding the inventory of the maintenance object to the maintenance plan table 61. Figure 8 is a diagram showing another example of a maintenance plan screen including a maintenance plan table displayed on the display unit according to the first embodiment.

The maintenance plan screen 60 shown in FIG. 8 displays a warning mark 68 as information regarding the inventory of the maintenance target. The warning mark 68 shown in FIG. 8 indicates that the value Ni obtained by subtracting the planned replacement quantity for the part "generator bearing" from the inventory quantity is equal to or less than the inventory threshold Na. This allows the manager U1 to easily understand that the part "generator bearing" needs to be replenished.

Next, the maintenance work screen displayed on the display unit 53 of the worker U2 will be described. The information acquisition unit 22 acquires, as maintenance item information, information on the maintenance targets and maintenance types for which maintenance work is scheduled for the current year from the schedule information 15 stored in the memory unit 10. The display processing unit 24 displays the maintenance work screen on the display unit 53 of the worker U2 based on the maintenance item information acquired by the information acquisition unit 22.

The maintenance work screen displayed on the display unit 53 includes information on the maintenance objects and maintenance types for which maintenance work is scheduled for the current year, and an input box for inputting the results of the maintenance work. By operating the input unit 52, worker U2 can input the results of the maintenance work into the input box on the maintenance work screen.

The input processing unit 21 accepts the results of the maintenance work entered in the input box. The update processing unit 25 updates the history information 14 based on the results of the maintenance work accepted by the input processing unit 21.

Next, the processing by the processing unit 20 of the maintenance plan creation support system 1 will be explained using a flowchart. FIG. 9 is a flowchart showing an example of processing by the processing unit of the maintenance plan creation support system according to the first embodiment.

As shown in FIG. 9, the processing unit 20 of the maintenance plan creation support system 1 determines whether or not there is a login request from the administrator U1 (step S10). If the processing unit 20 determines that there is a login request from the administrator U1 (step S10: Yes), it starts the administrator processing (step S11). The administrator processing is the processing of steps S20 to S29 shown in FIG. 10, and will be described in detail later.

When the processing of step S11 is completed, or when it is determined that there is no login request from the administrator U1 (step S10: No), the processing unit 20 determines whether there is a login request from the worker U2 (step S12). When it is determined that there is a login request from the worker U2 (step S12: Yes), the processing unit 20 starts the processing for the worker (step S13). The processing for the worker is the processing of steps S40 to S48 shown in FIG. 12, and will be described in detail later.

When the processing of step S13 is completed, or when it is determined that there is no login request from worker U2 (step S12: No), the processing unit 20 determines whether or not it is time to end the operation (step S14). For example, when it is determined that the power supply (not shown) has been turned off, the processing unit 20 determines that it is time to end the operation.

If the processing unit 20 determines that it is not time to end the operation (step S14: No), it transitions to step S10, and if it determines that it is time to end the operation (step S14: Yes), it ends the process shown in FIG. 9.

Figure 10 is a flowchart showing an example of a process for an administrator by a processing unit of the maintenance plan creation support system according to the first embodiment. As shown in Figure 10, the processing unit 20 determines whether authentication of the login request of the administrator U1 has been successful (step S20). For example, the processing unit 20 determines that authentication of the login request of the administrator U1 has been successful when the ID and password included in the login request of the administrator U1 match a preset ID and password.

When the processing unit 20 determines that the authentication of the login request of the administrator U1 is successful (step S20: Yes), it executes period-related processing (step S21). The period-related processing is the processing of steps S30 to S35 shown in FIG. 11, and will be described in detail later.

Next, the processing unit 20 acquires the maintenance information 11 and management information 12 from the memory unit 10 (step S22), and displays the maintenance plan screen 60 on the display unit 43 based on the acquired maintenance information 11 and management information 12 (step S23).

Next, the processing unit 20 determines whether the maintenance plan table 61 has been updated (step S24). If the processing unit 20 determines that the maintenance plan table 61 has been updated (step S24: Yes), it updates the maintenance information 11 (step S25). Note that if information on the production stop time Ts has been added to the maintenance plan table 61, the processing unit 20 also updates the management information 12 in the processing of step S25.

When the processing of step S25 is completed, or when it is determined that the maintenance plan table 61 has not been updated (step S24: No), the processing unit 20 calculates the value Ni obtained by subtracting the number of items to be replaced from the number of items in stock for each maintenance object (step S26).

Next, the processing unit 20 determines whether there is a conservation object for which the value Ni obtained by subtracting the planned replacement quantity from the inventory quantity is equal to or less than the inventory threshold value Na (step S27). If the processing unit 20 determines that there is a conservation object for which the value Ni obtained by subtracting the planned replacement quantity from the inventory quantity is equal to or less than the inventory threshold value Na (step S27: Yes), it causes the display unit 43 to display information regarding the inventory (step S28).

When the processing of step S28 is completed, or when it is determined that there is no conservation target for which the value Ni obtained by subtracting the planned replacement quantity from the inventory quantity is equal to or less than the inventory threshold value Na (step S27: No), the processing unit 20 determines whether or not there is a logout request from the administrator U1 (step S29). When it is determined that there is no logout request from the administrator U1 (step S29: No), the processing unit 20 transitions to the processing of step S21, and when it is determined that there is a logout request from the administrator U1 (step S29: Yes) or when authentication has failed (step S20: No), the processing unit 20 terminates the processing shown in FIG. 10.

Figure 11 is a flowchart showing an example of period-related processing by the processing unit of the maintenance plan creation support system according to the first embodiment. As shown in Figure 11, the processing unit 20 acquires information on the production stop time Ts (step S30).

Next, the processing unit 20 determines whether the time difference ΔTs between the production stop time Ts and the current year and month Tn is equal to or less than the threshold time period Tths (step S31). If the processing unit 20 determines that the time difference ΔTs is equal to or less than the threshold time period Tths (step S31: Yes), it notifies the logged-in user of information related to the production stop time Ts (step S32).

When the processing of step S32 is completed, or when the processing unit 20 determines that the period difference ΔTs is not equal to or less than the threshold period Tths (step S31: No), the processing unit 20 acquires information on the warranty period Tw (step S33). Then, the processing unit 20 determines whether the period difference ΔTw between the warranty period Tw and the current year and month Tn is equal to or less than the threshold period Tthw (step S34).

If the processing unit 20 determines that the period difference ΔTw is equal to or less than the threshold period Tthw (step S34: Yes), it notifies the logged-in user of information regarding the warranty period Tw (step S35). If the processing unit 20 has completed the process of step S35 or has determined that the period difference ΔTw is not equal to or less than the threshold period Tthw (step S34: No), it ends the process shown in FIG. 11.

Figure 12 is a flowchart showing an example of worker processing by the processing unit of the maintenance plan creation support system according to the first embodiment. As shown in Figure 12, the processing unit 20 determines whether or not authentication of the login request of worker U2 has been successful (step S40). For example, the processing unit 20 determines that authentication of the login request of worker U2 has been successful when the ID and password included in the login request of worker U2 match a preset ID and password.

Next, the processing unit 20 executes the period-related processing described above (step S41), and then the processing unit 20 acquires the maintenance item information of the maintenance target from the memory unit 10 (step S42), and displays the maintenance work screen on the display unit 53 based on the acquired maintenance item information (step S43).

Next, the processing unit 20 determines whether or not a maintenance result has been input by the worker U2 operating the input unit 52 (step S44). If the processing unit 20 determines that a maintenance result has been input (step S44: Yes), it updates the history information 14 based on the input maintenance result (step S45).

Next, the processing unit 20 determines whether or not a maintenance object is to be replaced based on the input maintenance result (step S46). If the processing unit 20 determines that a maintenance object is to be replaced (step S46: Yes), it updates the inventory information 13 (step S47). As a result, the inventory quantity of the replaced maintenance object is subtracted from the inventory quantity in the inventory information 13.

When the processing of step S47 is completed, when it is determined that no maintenance result has been input (step S44: No), or when it is determined that no replacement of the maintenance target has been performed (step S46: No), the processing unit 20 determines whether or not there has been a logout request from worker U2 (step S48). When it is determined that there has been no logout request from worker U2 (step S48: No), the processing unit 20 transitions to the processing of step S41, and when it is determined that there has been a logout request from worker U2 (step S48: Yes) or when authentication has failed (step S40: No), the processing unit 20 ends the processing shown in FIG. 12.

Fig. 13 is a diagram showing an example of the system configuration of the maintenance plan creation support system according to the first embodiment. As shown in Fig. 13, the maintenance plan creation support system 1 includes a server 3 and terminal devices 4 and 5. The server 3 and the terminal devices 4 and 5 can communicate with each other via a network 2. The network 2 includes, for example, a wide area network (WAN) such as the Internet and a mobile communication network.

Server 3 is a server built in cloud environment 6. Cloud environment 6 includes computer resources provided in a cloud service platform. The cloud service platform is provided by a cloud service provider and includes, for example, PaaS (Platform as a Service). Because server 3 is built in cloud environment 6, it is sometimes called a cloud server.

The terminal device 4 is a terminal device used by the manager U1, and the terminal device 5 is a terminal device used by the worker U2. The terminal devices 4 and 5 are, for example, tablet PCs (personal computers), notebook PCs, or smartphones.

The server 3 includes a communication unit 30, a processing unit 31, and a storage unit 10. The terminal device 4 includes a communication unit 40, a processing unit 41, an input unit 42, and a display unit 43. The terminal device 5 includes a communication unit 50, a processing unit 51, an input unit 52, and a display unit 53.

The communication units 30, 40, and 50 are connected to the network 2. The processing unit 20 includes processing units 31, 41, and 51, but may be configured by the processing unit 31. Note that the system configuration of the maintenance plan creation support system 1 is not limited to the example shown in FIG. 13.

In the above example, the maintenance plan creation support system 1 supports the creation of a maintenance plan on a year-month basis, but it can also support the creation of a maintenance plan on a year-month-day basis.

The information acquisition unit 22 can also acquire the manufacturer's web page or a production discontinuation notification email from the manufacturer, and extract information on the production discontinuation time Ts from the acquired information. In this case, the information acquisition unit 22 can update the management information 12 based on the extracted information on the production discontinuation time Ts. This allows the management information 12 to be updated without the need for the administrator U1 to operate the input unit 42.

The notification processing unit 23 can also increase the inventory threshold Na when the price of the maintenance object rises or when the delivery date is delayed, and can also increase the inventory threshold Na as the production stop time Ts approaches. This allows the administrator U1 to stably replenish maintenance objects.

The maintenance plan creation support system 1 can also store information on the free repair period provided by the manufacturer of the maintenance target in the storage unit 10. In this case, the display processing unit 24 can highlight the free repair period in the maintenance plan table 61, and the notification processing unit 23 can notify the logged-in user of information on the free repair period if the difference in time between the free repair period and the current year/month Tn is equal to or less than a threshold time.

In the above example, the notification processing unit 23 notifies the logged-in user of information, but it can also display emails or messages on the display units 43 and 53 by push notification when the user U is not logged in.

Fig. 14 is a diagram showing an example of the hardware configuration of a processing unit according to the first embodiment. As shown in Fig. 11, the processing units 20, 31, 41, and 51 include a computer having a processor 101, a memory 102, and a bus 103. The processor 101 and the memory 102 can transmit and receive information to and from each other via the bus 103.

The storage unit 10 is realized by the memory 102. The processor 101 executes the functions of the processing units 20, 31, 41, and 51 by reading and executing a program stored in the memory 102. The processor 101 is, for example, an example of a processing circuit, and includes one or more of a CPU (Central Processing Unit), a DSP (Digital Signal Processor), and a system LSI (Large Scale Integration).

The memory 102 includes one or more of a RAM (Random Access Memory), a ROM (Read Only Memory), a flash memory, an EPROM (Erasable Programmable Read Only Memory), and an EEPROM (Electrically Erasable Programmable Read Only Memory). The memory 102 also includes a recording medium on which a computer-readable program is recorded. Such a recording medium includes one or more of a non-volatile or volatile semiconductor memory, a magnetic disk, a flexible memory, an optical disk, a compact disk, and a DVD (Digital Versatile Disc). The processing units 20, 31, 41, and 51 may include integrated circuits such as an ASIC (Application Specific Integrated Circuit) and an FPGA (Field Programmable Gate Array).

As described above, the maintenance plan creation support system 1 according to the first embodiment includes an information acquisition unit 22, a display processing unit 24, and an update processing unit 25. The information acquisition unit 22 acquires maintenance information 11 including history information 14 including information indicating the inspection history and replacement history of the maintenance object, schedule information 15 including information indicating the scheduled inspection time and scheduled replacement time, and management information 12 including information indicating the production stop time Ts of the maintenance object. The display processing unit 24 displays a maintenance plan table 61 indicating information on the inspection history, the replacement history, the scheduled inspection time, the scheduled replacement time, and the production stop time Ts on the display unit 43 based on the maintenance information 11 and the management information 12. When the maintenance plan table 61 is updated, the update processing unit 25 updates the maintenance information 11 based on the update of the maintenance plan table 61. As a result, the maintenance plan creation support system 1 can support the creation of a preventive maintenance-type maintenance plan that takes into account the product life cycle of the maintenance object.

The display processing unit 24 also highlights each unit period after the production stop time Ts in the maintenance plan table 61. This allows the manager U1 in the maintenance plan creation support system 1 to easily understand the period after the production stop time in the maintenance plan table 61.

In addition, the management information 12 includes information indicating the warranty period of the maintenance object, and the maintenance plan table 61 includes information on the warranty period of the maintenance object. This allows the maintenance plan creation support system 1 to better support the creation of a preventive maintenance-type maintenance plan that takes into account the product life cycle of the maintenance object.

The display processing unit 24 also highlights each unit period that comes after the warranty period in the maintenance plan table 61. This allows the administrator U1 in the maintenance plan creation support system 1 to easily understand periods outside the warranty period in the maintenance plan table 61.

The notification processing unit 23 also notifies information about the production stop time Ts if the period until the production stop time Ts is within a preset period or if the production stop time Ts has passed. This allows the manager U1 in the maintenance plan creation support system 1 to easily grasp the period after the production stop time in the maintenance plan table 61.

The notification processing unit 23 also notifies information about the warranty period if the remaining period of the warranty period is within a preset period or if it has exceeded the warranty period. This allows the administrator U1 in the maintenance plan creation support system 1 to easily understand the period outside the warranty period in the maintenance plan table 61.

The information acquisition unit 22 also acquires inventory information 13 including the inventory quantity of the maintenance object and the inventory threshold Na. If the value Ni obtained by subtracting the planned replacement quantity of the maintenance object from the inventory quantity is equal to or less than the inventory threshold Na, the notification processing unit 23 notifies information regarding the inventory of the maintenance object. This allows the administrator U1 in the maintenance plan creation support system 1 to easily understand that a maintenance object needs to be replenished.

The configurations shown in the above embodiments are merely examples, and may be combined with other known technologies. Parts of the configurations may be omitted or modified without departing from the spirit of the invention.
