Mode for Carrying Out the Invention

[0011] <First Embodiment> [Overall Configuration Example of Water Storage Tank Facility Maintenance Support System] Hereinafter, the water storage tank facility maintenance support system according to the first embodiment will be described. In this embodiment, the water storage tank facility to be maintained by the water storage tank facility maintenance system is installed in, for example, an apartment building or a public facility, and is a facility for storing tap water supplied to each household in an apartment building or a public facility. Further, the water storage tank facility in this embodiment refers to a facility including facilities attached to the water storage tank such as pumps in addition to the water storage tank. Further, "maintenance" of the water storage tank facility in this embodiment may include cleaning, inspection, repair, maintenance, etc. of the water storage tank facility. Further, the "maintenance status" of the water storage tank facility may include the progress of maintenance work, the results of the performed maintenance work, the commission status of maintenance work to the trustee, etc.

[0012] Under this embodiment, for example, a consignor such as a management company or a local government of an apartment building entrusts a contractor with cleaning, inspection, repair, construction, etc. of a water storage tank. An operator of the contractor, who is the trustee, goes to the water storage tank facility installed at a designated location and performs work related to the maintenance of the water storage tank facility at the destination. The water storage tank facility maintenance support system of this embodiment is configured to manage information regarding the maintenance status of the water storage tank facility performed in this manner.

[0013] FIG. 1 shows an overall configuration example of the water storage tank facility maintenance support system according to the first embodiment. The water storage tank facility maintenance support system in the figure includes a consignor terminal 100, a trustee terminal 200, an operator terminal 300, a maintenance status management device 400, a map information server 500, and a water storage tank facility FC.

[0014] The consignor terminal 100 is a terminal device used by the consignor. The consignor terminal 100 may be, for example, a personal computer, a smartphone, a tablet terminal, or the like. A plurality of consignor terminals 100 may be provided corresponding to each of a plurality of consignors. Also, a plurality of consignor terminals 100 may be provided for the same consignor. The consignor terminal 100 is communicably connected to the trustee terminal 200 and the maintenance status management device 400 via the network NW.

[0015] The trustee terminal 200 is a terminal used by a person in charge at the contractor, who is the trustee, in relation to receiving a business order and the received business. The trustee terminal 200 may be, for example, a personal computer, a smartphone, a tablet terminal, or the like. A plurality of trustee terminals 200 may be provided corresponding to each of a plurality of trustees. Also, a plurality of trustee terminals 200 may be provided for the same contractor as the trustee. The trustee terminal 200 may be communicably connected to the consignor terminal 100, the maintenance status management device 400, the operator terminal 300, etc. via the network NW.

[0016] The worker terminal 300 is a terminal device used by worker WK, who works for the contractor, when performing maintenance work on the water storage tank facility FC. The worker terminal 300 may be a portable terminal device such as a smartphone or tablet. Multiple worker terminals 300 may be provided to correspond to each of the multiple contractors. Furthermore, multiple worker terminals 300 may be provided to correspond to each of the multiple workers WK within the same contractor. The worker terminal 300 may be connected to the contractor terminal 200 and the maintenance status management device 400 via a network NW to enable communication.

[0017] The maintenance status management device 400 manages information regarding the maintenance status of the water storage tank facility FC. In this embodiment, the maintenance status management device 400 stores information about the client (client-related information) and information about the contractor (contractor-related information). The status of the contract and the acceptance of contracts between the client and the contractor is grasped by the client-related information and the contractor-related information. Furthermore, the maintenance status management device 400 stores property management information that manages the maintenance status of water storage tank facilities subject to maintenance by the contractor on a property-by-property basis.

[0018] In this embodiment, "property" refers to one or more buildings or facilities, including a water storage tank facility, that the client has entrusted to a contractor for maintenance. The client can, for example, use a client terminal 100 that has access to the maintenance status management device 400 to entrust the maintenance of the water storage tank equipment to a contractor. In this case, the client can entrust the maintenance as a single unit (an example of a consolidated equipment unit) that is a collection of one or more buildings or facilities including the water storage tank equipment to be maintained. The client may register the entrustment by including one or more arbitrary buildings or facilities from among the buildings or facilities they own in a single unit. For example, the client may define a geographical area that is easy for them to manage regarding the buildings or facilities they own, and include the buildings or facilities within that defined geographical area in a single unit. The client may also include buildings or facilities selected based on a defined construction period for the water storage tank equipment in the buildings or facilities to be maintained in a single unit. Furthermore, the client may include buildings or facilities that share the same manufacturer or product category of water storage tank equipment to be maintained in a single unit. In this way, management is carried out on a per-property basis, including buildings and facilities selected by the client, making it easier for the client to manage the water storage tank equipment that they have entrusted to a contractor for maintenance. Furthermore, the operator of the water storage tank equipment maintenance support system in this embodiment can accurately grasp the maintenance status of the water storage tank equipment in accordance with the client's intentions. As a result, the operator can accurately make proposals to the client, such as future maintenance plans for the water storage tank equipment or suggestions for replacing the water storage tank equipment. Furthermore, for example, the client may register the water storage tank facilities or buildings and facilities equipped with water storage tank facilities to be entrusted for maintenance to the maintenance status management device 400 without considering the individual properties. Then, for example, the maintenance status management device 400 may manage the registered water storage tank facilities or buildings and facilities by classifying them into "properties" that fall under predetermined classification conditions or classification conditions specified by the client, thereby managing them on a "property" basis.

[0019] The maintenance status management device 400 displays a maintenance status screen on the client terminal 100, in response to access from the client terminal 100, which shows the status of maintenance work performed by the contractor to the client. The maintenance status management device 400 may provide a maintenance status provision site as a website, which provides information on the maintenance status of the entrusted property to the client terminal 100. When the client terminal 100 logs into the maintenance status provision site via a web browser, the maintenance status provision site screen (web page) is displayed on the client terminal 100. The client can understand the maintenance status of the entrusted water tanks on a property-by-property basis by viewing the maintenance status information site screen displayed on the client terminal 100.

[0020] Furthermore, the maintenance status management device 400 may also provide a maintenance work support application as a web application, which is operated by the worker on the worker terminal 300. The maintenance work support application is an application that supports maintenance work on the water storage tank equipment FC, such as cleaning, inspection, repair, and construction work on the water storage tank equipment FC. When the worker terminal 300 logs in to the web server compatible with the maintenance work support application of the maintenance status management device 400 via a web browser, the maintenance work support application screen is displayed on the worker terminal 300, and the worker can operate the maintenance work support application screen.

[0021] Workers (WK) are instructed to use maintenance support applications when performing cleaning or inspection tasks. For example, workers (WK) use the maintenance support applications to record the progress of cleaning during cleaning tasks, or to confirm work details and input inspection results during inspection tasks.

[0022] Alternatively, instead of the web application that supports the maintenance work described above, a maintenance work support application as application software may be pre-installed on the worker terminal 300. Alternatively, the worker terminal 300 may access the web server of the maintenance status management device 400, thereby enabling the maintenance work support application to be installed on the worker terminal 300 from the maintenance status management device 400. Alternatively, the worker terminal 300, acting as a thin client, may access the web server of the maintenance status management device 400, thereby enabling the worker terminal 300 to operate the maintenance work support application.

[0023] The maintenance status management device 400 may be provided as a server on a network. Alternatively, the maintenance status management device 400 may be provided as a cloud server.

[0024] The map information server 500 is a server that provides map information. The maintenance status management device 400 can acquire map information from the map information server 500 and use the acquired map information to display a map image showing the location of the water storage tank facility FC.

[0025] [About the screen on the conservation status information site] The client uses a maintenance status information site accessed via the client terminal 100 to ascertain the maintenance status of the water storage tank facility FC, which the client has entrusted to a contractor for maintenance. Refer to Figures 2 to 9 to explain examples of screen layouts for conservation status information websites. When the client accesses the maintenance status provision site using the client terminal 100 and logs in, the top page of the maintenance status provision site is displayed first. From the top page of the maintenance status provision site, it is possible to navigate to the property management webpage. When the operation to navigate to the property management webpage is performed, the property list screen is displayed first as the property management webpage. The property list screen is a screen that displays information about the water storage tank facilities for which the client has entrusted maintenance, categorized by property.

[0026] Figures 2 to 4 show examples of the property list screen. Figures 2, 3, and 4 sequentially show the property list screen divided from left to right. As shown in Figure 2, the property information area AR1 is initially located at the far left of the property list screen. The property information area AR1 is the area where the name of each property (property name) of the contracted party is displayed. In the diagram, an example is shown where the list item Lt1 for each property is Lt1-1 for "Property A" and Lt1-2 for "Property B". In other words, the example in the diagram shows a situation where the client has contracted the maintenance of water storage facilities for two properties.

[0027] Furthermore, the building information area AR2 is located to the right of the property information area AR1. The building information area AR2 is an area where information (building information) for one or more buildings included in the property is displayed. Figure 2 shows an example where property A includes two buildings, "Building A1" and "Building A2," and property B also includes two buildings, "Building B1" and "Building B2," with building information presented for each of these buildings.

[0028] Figure 2 shows an example where building information is presented with the following items: building name, prefecture, city / ward / town / village, address, and building manager information. The building name information indicates the name of the corresponding building. The prefecture information indicates the prefecture where the corresponding building is located. The municipal information indicates the municipality where the corresponding building is located. The address information indicates the address where the corresponding building is located. The building manager information will indicate the building manager responsible for the actions specified by the client.

[0029] As shown in Figure 3, the water storage tank equipment information (tank information) area AR3 is located to the right of the building information area AR2 on the property list screen. The water storage tank information area AR3 is an area that displays information (water storage tank information) for one or more water storage tank facilities installed in the building. The diagram shows an example where two water storage tanks with management numbers "A1-001" and "A1-002" are installed in "Building A1", two water storage tanks with management numbers "A2-001" and "A2-002" are installed in "Building A2", two water storage tanks with management numbers "B1-001" and "B1-002" are installed in "Building B1", and one water storage tank with management number "B2-001" is installed in "Building B2".

[0030] In Figure 3, the following items are presented as water storage tank information: importance, management number, equipment number (equipment No.), purpose 1, purpose 2, installation location, tank material, dimensions, capacity, effective capacity, manufacturer, installation date, and elapsed years. The importance level information indicates the importance level set for the corresponding water storage tank facility. The importance level may be set by the client, but depending on the operation, it may also be set by the contractor. The management number information indicates the management number assigned to the corresponding water storage tank facility. The equipment number information indicates the equipment number assigned to the corresponding water storage tank facility. The information for Use 1 indicates the intended use of the water stored in the corresponding water storage facility. Information for Use 2 indicates whether the corresponding water storage facility is a receiving tank or an elevated water tank. The installation location information indicates the location where the corresponding water storage tank equipment is installed within the building. The tank material information indicates the material used in the corresponding water storage facility. The dimensional information indicates the dimensions (width (W), depth (D), height (H)) of the corresponding water storage tank equipment. The capacity information indicates the capacity determined based on the dimensions of the corresponding water storage tank facility. The effective capacity information indicates the effective capacity (effective capacity) for the corresponding water storage facility. The effective capacity will be less than the capacity shown above. The manufacturer information indicates the manufacturer that produced the corresponding water storage tank equipment. The installation date information indicates the year and month in which the corresponding water storage tank equipment was installed. The date may also be included in addition to the year and month. The elapsed time information indicates the number of years that have passed since the corresponding water storage tank facility was installed.

[0031] As shown in Figure 4, the Inspection (Diagnosis) Results Area AR4 is located to the right of the Water Storage Tank Information Area AR3 on the property list screen. The Inspection Results Area AR4 displays the inspection results reported by the contractor after inspection work has been carried out for each water storage tank facility. In the Inspection Results Area AR4 shown in the figure, the inspection results for each inspection item based on the provisions of the Waterworks Act and the inspection results for each inspection item related to the seismic performance and deterioration of the water tank body are displayed. In addition, the overall diagnosis result is displayed on the far left of the Inspection Results Area AR4. The overall diagnosis result shows the diagnosis result determined by comprehensively integrating the inspection results for each inspection item on the right for the corresponding water storage tank facility.

[0032] The overall diagnostic result may be determined by the maintenance work support application based on the content of the inspection results entered for each inspection item by the worker through operations on the worker terminal 300. Alternatively, the overall diagnostic result may be determined by the maintenance status management device 400 based on the content of the inspection results for each inspection item included in the inspection result report information transmitted from the worker terminal 300 of worker WK who inspected the corresponding water storage tank equipment.

[0033] The maintenance status management device 400 may obtain inspection result report information used for determining the overall diagnostic result in the following manner. When worker WK is performing inspection work on the water storage tank equipment, he may display the inspection result input screen as the application screen of the maintenance work support application on the worker terminal 300. Worker K can perform the operation of inputting inspection results for each inspection item presented on the inspection result input screen. When worker WK has finished inputting the inspection results into the inspection result input screen, he performs an operation to instruct the reporting of the inspection results. In response to this operation, the worker terminal 300 transmits inspection result report information indicating the inspection results entered on the inspection result input screen to the maintenance status management device 400. The maintenance status management device 400 acquires the transmitted inspection result report information. The maintenance status management device 400 may store the acquired inspection result report information in association with the water storage tank equipment that was inspected.

[0034] In the property information area AR1 of the property list screen in Figure 2, the property name portion of the property-specific list item Lt1 has a hyperlink set. In other words, in the example in Figure 2, the property name "Property A" in the property-specific list item Lt1-1 and the property name "Property B" in the list item Lt1-2 have hyperlinks set.

[0035] When the hyperlink in the property name section is opened, the user is redirected to a maintenance work-related screen that displays information related to the maintenance work commissioned for the corresponding property. The maintenance work-related screen includes a cleaning-related screen related to maintenance work such as cleaning of water storage tank facilities, a repair-related screen related to maintenance work such as repair of water storage tank facilities, and a construction-related screen related to construction work on water storage tank facilities. When the hyperlink in the property name section is opened, the system may first transition to one of the following maintenance-related screens: a cleaning-related screen, a repair-related screen, or a construction-related screen. In the following explanation, we will use the example where the cleaning-related screen is displayed first when the hyperlink in the property name section is opened.

[0036] Figures 5 and 6 show an example of a cleaning-related screen for Property A, which is displayed when the hyperlink for the property name "Property A" in Figure 2 is opened. Figures 5 and 6 sequentially show the cleaning-related screen divided from left to right.

[0037] As shown in Figure 5, the cleaning-related screen includes a screen change operation area AR11 and a cleaning-related information area AR12.

[0038] The screen change operation area AR11 is an area where you can change the displayed screen between cleaning-related screens, repair-related screens, and construction-related screens. The screen change operation area AR11 is also displayed when a repair-related screen or a construction-related screen is being displayed.

[0039] In the screen change operation area AR11, screen transition buttons BT11, BT12, BT13, and BT14 are located. The screen transition button BT11 is used to transition to the cleaning-related screen when a repair-related screen or construction-related screen is displayed. In this case, since the cleaning-related screen is displayed, the screen transition button BT11 will be displayed in a grayed-out state and will be unusable. The screen transition button BT12 is used to transition from a cleaning-related screen or a construction-related screen to a repair-related screen. The screen transition button BT13 is used to transition from a cleaning-related screen or a repair-related screen to a construction-related screen. The screen transition button BT13 is used to transition to the property list screen when one of the following screens is displayed: a cleaning-related screen, a repair-related screen, or a construction-related screen.

[0040] The cleaning-related information area AR12 is an area where information regarding cleaning work for water storage facilities at the corresponding property is presented. In the case of "Property A," which has two buildings, "Building A1" and "Building A2," the cleaning-related information area AR12 contains building-specific areas AR121 and AR122, corresponding to "Building A1" and "Building A2," respectively, arranged in a vertical relationship. Furthermore, "Building A1" has two water storage tank facilities with management numbers "A1-001" and "A1-002". Therefore, in building-specific area AR121, there is a record that displays information corresponding to the water storage tank facility with management number "A1-001", and below that record, there is a record that displays information corresponding to the water storage tank facility with management number "A1-002". Furthermore, "Building A2" has two water storage tank facilities with management numbers "A2-001" and "A2-002". Therefore, in building-specific area AR122, there is a record that displays information corresponding to the water storage tank facility with management number "A2-001", and below that record, there is a record that displays information corresponding to the water storage tank facility with management number "A2-002".

The repair completion documents may be uploaded from the contractor's terminal 200 or from the contractor's terminal 200 of the corresponding contractor. If the repair completion documents have been uploaded, the repair completion documents section will contain a hyperlink to the download page for those documents.

[0056] Opening the hyperlink for the "Completed Repair Documents" item will display the download page for the corresponding "Completed Repair Documents." The client can then download the "Completed Repair Documents" by following the instructions on the displayed download page. Alternatively, opening the hyperlink for the "Completed Repair Documents" item may open the "Completed Repair Documents" document itself.

[0057] The "Repair Details" section outlines the specific repairs that will be carried out.

[0058] Next, with reference to Figure 8, an example of a maintenance work-related screen as a construction-related screen will be described. As shown in Figure 8, the construction-related screen includes a screen change operation area AR11 and a construction-related information area AR14. In this case, in the screen change operation area AR11, a construction-related screen is displayed, and among the screen transition buttons BT11 to BT14, the screen transition button BT13, which corresponds to the construction-related screen, is grayed out and cannot be operated.

[0059] The construction-related information area AR14 is an area where information regarding construction work on the water storage facility targeted in the corresponding property is presented. In the diagram, this corresponds to the case where one water storage facility in "Building A2" of "Property A" is the target of construction. In this case, as shown in Figure 8, in the construction-related information area AR14, one building-specific area AR141 corresponding to "Building A2" may be placed, and in the building-specific area AR141, a record corresponding to one water storage facility may be placed.

[0060] In the construction-related information area AR14, records for water storage tank facilities are displayed from left to right, with the following items: status, year, project name, and contractor information. The status information indicates the status (construction status) of the corresponding water storage facility construction. The construction status may also indicate the progress of the construction. The year information indicates the year in which the contractor will carry out the construction of the corresponding water storage facility. The information regarding the contractor refers to the contractor (employer) responsible for the construction of the water storage tank facilities.

[0061] The information provided by the contractor includes the performance period, construction company, address, telephone number (TEL), contact person, completion documents, and details of the work. The "Performance Period" item indicates the period during which the construction of the corresponding water storage facility should be carried out. The "Contractor" section indicates the contractor responsible for the construction of the corresponding water storage tank facility, using the contractor's name. The address field indicates the address of the contractor handling the request. The "Telephone Number (TEL)" field indicates the telephone number of the service provider handling the inquiry. The "Person in Charge" field indicates the construction manager at the contractor handling the matter.

[0062] The "Completion Documents" item indicates whether the completion documents (construction completion documents) corresponding to the construction of the water storage facility have been uploaded to the maintenance status management device 400. The construction completion documents may be uploaded from the contractor's terminal 200 or from the contractor's terminal 200 of the corresponding contractor. If the construction completion documents have been uploaded, the section for the construction completion documents will contain a hyperlink to the download page for those documents.

[0063] Opening the hyperlink in the "Construction Completion Documents" section will display the download page for the corresponding construction completion documents. The client can then download the construction completion documents by following the instructions on the displayed download page. Alternatively, opening the hyperlink in the "Construction Completion Documents" section may open the construction completion documents themselves.

[0064] The "Construction Details" section outlines the specific details of the work being carried out.

[0065] Next, let's explain the map screen. The map screen is one of the screens displayed on the property management webpage of the conservation status provision site. The property list screen includes a section for displaying the address information for each building (Figure 2). The address displayed in this section is linked to a hyperlink. When this hyperlink is opened, the display transitions from the property list screen to the map screen.

[0066] Figure 9 shows an example of a map screen. The map screen in this figure consists of a map area AR21 and a route setting area AR22. Map area AR21 displays a map. The map displayed in map area AR21 has pins placed for each water storage facility installed in the building at the address to which the corresponding hyperlink was placed. Specifically, in the case of Figure 9, since there are two water storage facilities installed in the building at the corresponding address, two corresponding pins P(P-1, P-2) are placed for each of the two installed water storage facilities. The map in map area AR21 can be displayed using map information acquired by the maintenance status management device 400 from the map information server 500.

[0067] The map scale in map area AR21 can be changed. When the scale becomes smaller than a certain level, for example, two pins P (P-1, P-2) will be combined into a single symbol indicating the number of pins.

[0068] Furthermore, when a pin P is specified, a water storage facility screen may be displayed (though not shown in the illustration) that presents information about the corresponding water storage facility. The water storage facility screen may be, for example, a pop-up screen superimposed on the map screen. The water storage facility screen may display items such as the corresponding property name, corresponding building name, corresponding address, purpose of the water storage facility (Purpose 1, Purpose 2), water tank material, effective capacity, dimensions, and importance. Furthermore, the water storage tank equipment screen may be configured to allow users to transition to the property list screen, for example, by placing a button on it.

[0069] Route setting area AR22 is the area where operations are performed to set a route from the starting point to the destination. For example, the client enters the address of the starting point in the starting point input area AR221 within the route setting area AR22. The starting point may be, for example, the client's address. Furthermore, the starting point address may be set to a fixed value. Furthermore, in the route setting area AR22, the destination input area AR222 is located below the departure point input area AR221. The destination input area AR222 is an area where the destination is entered in response to user input. The destination may be entered into the destination input area AR222 by specifying one of the pins P located in the map area AR21. The client's operator enters the departure and destination points as described above, and then performs an operation to instruct the system to perform a route search (route search instruction operation). This route search instruction operation may be performed on the route search (search) button BT21 located in the route setting area AR22. In response to a route search instruction operation, a map image showing the searched route is displayed. The map image showing the searched route may be displayed on a different screen than the map image in Figure 9, or it may be displayed in map area AR21. Furthermore, the maintenance status management device 400 may have the map information server 500 search for a route corresponding to the input departure point and destination.

[0070] [Example of Functional Configuration of a Maintenance Status Management System] Referring to Figure 10, an example of the functional configuration of the maintenance status management device 400 will be described. The maintenance status management device 400 may be configured with hardware such as a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), and storage devices such as an HDD (Hard Disk Drive) or SSD (Solid State Drive). The maintenance status management device 400 may also be equipped with a GPU (Graphics Processing Unit) as hardware. The functions of the maintenance status management device 400 shown in the figure are realized by the CPU and GPU in the maintenance status management device 400 executing programs.

[0071] The maintenance status management device 400 in the figure comprises a communication unit 401, a control unit 402, and a storage unit 403. The communication unit 401 is connected to the client terminal 100, the contractor terminal 200, the worker terminal 300, and the map information server 500 via the network NW, enabling communication between them.

[0072] The control unit 402 performs various controls in the maintenance status management device 400. The control unit 402 includes a screen control unit 421. The screen control unit 421 executes control to display the screen provided as a web page by the maintenance status provision site on a terminal device such as the client terminal 100 that has logged into the maintenance status provision site. At this time, the screen control unit 421 transmits the web page data as a screen to the terminal device such as the client terminal 100 to display the corresponding screen.

[0073] The storage unit 403 stores various types of information corresponding to the maintenance status management device 400. The storage unit 403 includes a client-related information storage unit 431, a contractor-related information storage unit 432, and a property management information storage unit 433.

[0074] The client-related information storage unit 431 stores client-related information for one or more clients. Each piece of client-related information includes predetermined information related to the corresponding client.

[0075] Figure 11 shows an example of client-related information corresponding to one client. The client-related information corresponding to one client is associated with a client ID that identifies the corresponding client. Client-related information includes fields for client name, address, and information about the entrusted property. Furthermore, client-related information may also include information such as the client's phone number, email address, and contact person.

[0077] The address field stores the address of the client in question. Furthermore, client-related information may include the client's phone number, email address, and contact person.

[0078] The field for entrusted property information stores information about entrusted properties. Entrusted property information indicates the status of maintenance work entrusted by the relevant client on a property-by-property basis. Specifically, the entrusted property information may have a structure in which a contractor ID, indicating the contractor (contractor) to whom maintenance work has been entrusted, is associated with each property for which the relevant client has entrusted maintenance work.

[0079] Let's return to the explanation in Figure 10. The contractor-related information storage unit 432 stores contractor-related information for one or more contractors. Each piece of contractor-related information includes predetermined information related to the corresponding contractor.

[0080] Figure 12 shows an example of contractor-related information corresponding to one contractor. The contractor-related information corresponding to one contractor is associated with a contractor ID that identifies the corresponding contractor. Contractor-related information includes the contractor's name, address, and information about the contracted property. Furthermore, contractor-related information may also include the corresponding contractor's telephone number, email address, and contact person.

[0081] The "Contractor Name" field stores the name of the corresponding contractor.

[0082] The address field stores the address of the corresponding contractor. Furthermore, contractor-related information may also include the contractor's telephone number, email address, and contact person.

[0083] The field for entrusted property information stores information about entrusted properties. Entrusted property information indicates the status of maintenance work undertaken by the corresponding contractor on a property-by-property basis. Specifically, the entrusted property information may have a structure in which the client ID, which indicates the client company (client), is associated with each property for which the corresponding contractor has been entrusted with maintenance work.

[0084] The client-related information stored in the client-related information storage unit 431 and the contractor-related information stored in the contractor-related information storage unit 432 indicate the relationship between the client and the contractor regarding the entrustment and acceptance of the property.

[0085] Let's return to the explanation in Figure 10. The property management information storage unit 433 stores property management information for each property. Figure 13(A) shows an example of the structure of property management information corresponding to a single property. The property management information in this figure includes fields for property ID, property name, and one or more property information fields (1 to n). The Property ID field stores a property ID that uniquely identifies the corresponding property. The property name field stores the name of the corresponding property. The property name stored in this field may be presented as the property name in property information area AR1. Each building information field stores building information for a single corresponding building.

[0086] Figure 13(B) shows an example of the structure of a single building information. The building information in this figure includes fields for building ID, building name, address, building manager, and one or more water tank information fields (1 to n). The Building ID field stores a Building ID that uniquely identifies the corresponding building. The Building Name field stores the name of the corresponding building. The Building Name stored in this field may be displayed as the Building Name in the Building Information Area AR2 (Figure 2) of the Property List screen. The address field stores the address of the corresponding building. The address stored in this address field may be displayed as the address in the building information area AR2 on the property list screen. The Building Manager field stores information about the building manager designated as the person responsible for managing the corresponding building. The information about the building manager stored in this field may be presented as the building manager in the building information area AR2 on the property list screen. A field for one water storage tank information stores information about the corresponding one water storage tank.

[0087] Figure 13(C) shows an example of the structure of one water storage tank information. The water storage tank information in this figure includes fields for importance, management number, equipment number, use 1, use 2, installation location, water storage tank specifications, installation date, years elapsed, contractor, cleaning status, repair status, construction status, cleaning report, water supply inspection report, inspection result report, repair completion documents, and construction completion documents.

[0088] The importance field stores the importance level set for the corresponding water storage facility. The management number field stores the management number set for the corresponding water storage tank facility. The equipment number field stores the equipment number assigned to the corresponding water storage facility. The "Use 1" field stores information indicating the intended use (Use 1) of the water stored in the corresponding water storage facility. The field for Use 2 stores information indicating whether the corresponding water storage facility is a receiving tank or an elevated water tank (Use 2). The installation location field stores the location (installation site) where the corresponding water storage facility is installed within the building. The water tank specifications field stores information indicating the specifications of the water tank. This information may include, for example, the tank material, dimensions, capacity, effective capacity, and manufacturer. The field for installation date stores the installation date of the corresponding water storage tank equipment. The "Years Elapsed" field stores the number of years elapsed for the corresponding water storage tank equipment. The screen control unit 421 of the maintenance status management device 400 may store the number of years elapsed, calculated based on the installation date stored in the "Installation Date" field and the current date, in the "Years Elapsed" field. The "Contractor" field includes information about the contractor (contractor information). This contractor information may include the contractor's company name, address, telephone number, contact person, and performance period.

[0089] The information stored in the fields for Importance, Management Number, Equipment Number, Use 1, Use 2, Installation Location, Water Tank Specifications, Installation Date, and Elapsed Years may be presented as information for each item in the Water Tank Information Area AR3 on the property list screen. Information stored in the contractor's field may be presented as information in the contractor's item on cleaning-related screens. Furthermore, the elapsed years of the corresponding water storage tank equipment in the water storage tank information area AR3 of the property list screen may be calculated by the screen control unit 421 of the maintenance status management device 400 based on the installation date stored in the water storage tank information and the current date. Alternatively, the elapsed years may also be calculated by the screen control unit 421 and stored in the water storage tank information.

[0090] The cleaning status field stores the cleaning status of the corresponding water storage facility. The maintenance status management device 400 may store the cleaning status transmitted from the contractor's terminal 200 or worker's terminal 300 of the corresponding contractor in the cleaning status field. The cleaning status information stored in the cleaning status field may be displayed in the status item in the cleaning-related information area AR12 (Figure 5) of the cleaning-related screen.

[0091] The repair status field stores the repair status of the corresponding water storage facility. The maintenance status management device 400 may store the repair status transmitted from the contractor's terminal 200 or worker's terminal 300 of the corresponding contractor in the repair status field. The repair status information stored in the field for the repair status may be displayed in the status item in the repair-related information area AR13 (Figure 7) of the repair-related screen.

[0092] The Construction Status field stores the repair status of the corresponding water storage facility. The maintenance status management device 400 may store the Construction Status transmitted from the contractor's terminal 200 or worker's terminal 300 of the corresponding contractor in the Construction Status field. The construction status information stored in the relevant construction status field may be displayed in the status item in the construction-related information area AR14 (Figure 8) of the construction-related screen.

[0093] The field for "Repair Completion Documents" stores the uploaded repair completion documents for the corresponding water storage tank equipment once they have been uploaded. If the Repair Completion Documents field contains the Repair Completion Documents that have been uploaded, the Repair Completion Documents item in the Repair Related Information Area AR13 (Figure 7) of the Repair Related Screen will have a link to the URL of the Repair Completion Documents stored in that field.

[0094] The Construction Completion Documents field stores the uploaded Construction Completion Documents for the corresponding water storage facility once they have been uploaded. If the completed construction documents uploaded to the completed construction documents field are stored there, the completed documents item in the construction-related information area AR14 (Figure 8) of the construction-related screen will have a link to the URL of the completed construction documents stored in that field.

[0095] As can be understood from the above explanation, the water storage tank equipment maintenance support system of the first embodiment allows the client terminal 100 to access the maintenance status provision site, and displays a property list screen (Figures 2 to 4) on the client terminal 100. This screen presents a list of information about the building, the water storage tank equipment installed in the building, and the inspection results for each water storage tank equipment, for each property for which maintenance work on the water storage tank equipment has been commissioned. By presenting the property list screen in this way, the first embodiment makes it possible to comprehensively grasp the maintenance status of the water storage tank equipment on a property-by-property basis. Furthermore, by opening the hyperlinks set on the property list screen, it becomes possible to transition to the respective screens for each property: a cleaning-related screen for cleaning water storage tank facilities, a repair-related screen for repairing water storage tank facilities, and a construction-related screen for construction work on water storage tank facilities. Furthermore, various reports and completion documents can be downloaded from the cleaning-related screen, repair-related screen, and construction-related screen, respectively. Furthermore, by opening the hyperlink set for the building address displayed on the property list screen, users can transition to a map image showing the location of the water storage tank facilities installed in the corresponding building. Thus, in the first embodiment, the client terminal 100 displays a list of properties, and from that property list screen, it is possible to display cleaning-related screens, repair-related screens, and construction-related screens for each property. By displaying such screens, the client can more comprehensively and efficiently grasp the progress of the commissioned maintenance work and the results of the maintenance work that has been performed.

[0096] Furthermore, access to the maintenance status information site may be made possible on terminals other than the client terminal 100, such as the contractor terminal 200, if the necessary permissions are granted. In this case, it may be possible to set access permissions for each webpage of the maintenance status information site, allowing access or not.

[0097] <Second Embodiment> Here, we will describe a water storage tank equipment maintenance support system according to a second embodiment. This embodiment differs from the first embodiment in that the maintenance status management device 400 formulates a maintenance plan based on the maintenance status of the water storage tank equipment. In the following description, we will mainly describe the differences from the first embodiment, and the same reference numerals will be used for parts that are the same as in the first embodiment, and their descriptions will be omitted.

[0098] Traditionally, whenever it was determined that repairs or replacements (upgrades) of parts in water storage tank facilities were necessary, these were addressed on a case-by-case basis. Therefore, if a large number of repairs or replacements were needed in a short period, it could become difficult to provide adequate support. For example, water storage tanks are mostly manufactured on a build-to-order basis, and a large number of replacements concentrated in a short period could overwhelm production. Furthermore, because local governments manage multiple water storage tank facilities, simultaneous repairs or replacements to multiple facilities could exceed the budget. Additionally, securing workers to perform a large number of repairs or replacements becomes difficult. If water storage tank facilities are not properly maintained, it can lead to damage. Damage to water storage tank facilities can result in a water outage. When water becomes unavailable, it is necessary to repair or replace the water storage tank facilities as quickly as possible, but because water storage tank facilities are mostly manufactured on a build-to-order basis, prompt action is difficult. In light of these circumstances, in this embodiment, the maintenance status management device 400 is configured to formulate maintenance work plans based on the maintenance status of the water storage tank equipment. As a result, the water storage tank equipment maintenance support system of the second embodiment can support the repair or replacement of parts in the water storage tank equipment to be carried out efficiently at the appropriate time.

[0099] In this embodiment, "maintenance work" for the water storage tank equipment may include not only the cleaning, inspection, repair, and servicing work of the water storage tank equipment as described in the above-described embodiment, but also work related to the replacement (upgrade) of the water storage tank equipment. More specifically, "maintenance work" may include repair work, which is work to restore the function of the water storage tank equipment to its original state after a malfunction has occurred, and maintenance work, which is work to prevent malfunctions even though no malfunction has occurred in the water storage tank equipment, or to maintain the water storage tank equipment in good condition. Furthermore, "maintenance work" may include not only actual work such as replacement of parts, repair, and replacement (upgrade) of water storage tank equipment, but also investigations before performing these works, such as detailed investigation of faulty areas, investigation of the progress of deterioration, creation of maintenance plans, and creation of estimates.

[0100] Figure 14 shows an example of the functional configuration of the maintenance status management device 400 according to the second embodiment. The control unit 402 of the maintenance status management device 400 in the figure includes a maintenance information generation unit 422. The storage unit 403 includes a maintenance information storage unit 434. The maintenance information generation unit 422 generates maintenance information and stores the generated maintenance information in the maintenance information storage unit 434. The maintenance information includes information related to the maintenance of the water storage tank equipment.

[0101] Figure 15 shows an example of maintenance information. In this figure, the maintenance information includes fields such as management information, maintenance necessity, urgency, target location, and content. The management number field corresponds to the management information in the water storage tank information shown in Figure 13(C), and stores the management number set for the corresponding water storage tank equipment. The maintenance requirement field stores whether or not maintenance work is required for the corresponding water storage facility. The urgency field stores the urgency of maintenance work required for the corresponding water storage facility. The field for the target location stores the location where maintenance work is to be performed on the corresponding water storage facility, in cases where such maintenance work is required. The content field stores the specific details of the maintenance work to be performed on the corresponding water storage facility, if such maintenance work is required.

[0102] The maintenance information generation unit 422 generates maintenance information. First, the maintenance information generation unit 422 determines whether maintenance work is necessary for the water storage tank facility. For example, the maintenance information generation unit 422 can use machine learning technology to determine whether maintenance work is necessary based on photographs taken of the water storage tank facility. Photographs of the water storage tank facility can include, for example, photographs taken during cleaning or inspection work, or more specifically, photographs attached to cleaning reports, inspection result reports, etc.

[0103] The maintenance information generation unit 422 first generates a trained model used to determine whether maintenance work is necessary. The maintenance information generation unit 422 generates a training dataset in which training photographs (training data) are associated with the determination results (labels) of whether maintenance work is necessary. Past performance, i.e., photographs taken during cleaning work and inspection work, can be used as training photographs. The determination of whether maintenance work is necessary may be made by a human looking at the photographs, or it may be made using inspection results obtained by workers during inspection work according to the inspection items.

[0104] For example, the inspection of the top of the water tank includes items such as taking photographs showing the condition of the top panel (overall photo, close-up photo of the panel section, close-up photo of the cross section, etc.), and checking for openings where rainwater may enter, gaps in joints, major damage or cracks in the top panel, and deformation, damage, or rust on the bolts. The maintenance information generation unit 422 uses the photographs taken according to these inspection items as training data and can use the inspection results, such as checking for rust, as labels.

[0105] The conservation information generation unit 422 generates a trained model by training the training model with the training dataset. As the training model, for example, a classifier using a CNN (Convolutional Neural Network) can be used. Alternatively, an SVM (Support Vector Machine) based on photographic features can be applied as the training model. The maintenance information generation unit 422 trains a learning model using a training dataset to learn the correspondence between photographs and the necessity of maintenance work. This trains the learning model until it can correctly determine the necessity of maintenance work based on the state of the water tank equipment captured in the photograph. The maintenance information generation unit 422 then designates the learning model that has been trained to correctly determine the necessity of maintenance work from photographs as the trained model. The trained model generated in this way is configured to output, for example, the degree to which maintenance work is necessary for the water storage facility photographed in the photograph, based on the photograph input to the trained model, and functions as a maintenance work necessity determination model.

[0106] Furthermore, when determining the necessity of maintenance from each of the multiple perspectives, the maintenance information generation unit 422 may generate multiple trained models corresponding to each of the multiple perspectives. For example, in the inspection of water storage tank facilities, major categories are established for the surrounding area, the top of the tank, the inside of the tank, and the outside of the tank. Within each of these major categories, there are further sub-categories and minor categories, resulting in a wide range of inspection work. The maintenance information generation unit 422 can generate trained models for determining whether maintenance work is necessary for each of these major, medium, or minor inspection items. Specifically, the maintenance information generation unit 422 can generate trained models corresponding to each of the items set as sub-items for inspections related to the upper part of the tank as a major category, such as the top plate, MH (manhole), electrodes / water supply valve, vents, pipe connections, and external ladders. Furthermore, the maintenance information generation unit 422 can generate trained models corresponding to each of the items set as sub-items for inspections related to the inside of the tank as a major category, such as the internal ladder and the inside of the tank. Furthermore, the maintenance information generation unit 422 can generate trained models corresponding to each of the items set as sub-items for inspections related to the outside of the tank as a major category, such as the side plates, pipe connections, bottom plates, and foundations.

[0107] The maintenance information generation unit 422 uses the trained model generated in this way to determine whether maintenance work is necessary based on photographs taken of the water storage tank equipment. The maintenance information generation unit 422 acquires photographs (photographs of the water storage tank equipment) attached to cleaning reports, inspection result reports, etc., uploaded to the maintenance status management device 400 from the contractor's worker terminal 300 (or contractor terminal 200). The maintenance information generation unit 422 inputs the acquired photographs into the trained model and acquires the output data output from the trained model in response to the input of photographs as a determination result indicating whether maintenance work is necessary. As a result, the maintenance information generation unit 422 can determine whether maintenance work is necessary for the water storage tank equipment.

[0108] The maintenance information generation unit 422 generates maintenance information based on the determination results made using the trained model. For example, the maintenance information generation unit 422 sets whether or not maintenance work is required in the maintenance information based on the output from the trained model. Furthermore, the maintenance information generation unit 422 sets the urgency level in the maintenance information according to the maintenance necessity level output from the trained model. Furthermore, the maintenance information generation unit 422 sets the target location and content in the maintenance information based on the content of the training dataset that was used to train the trained model used to determine whether maintenance is necessary. The maintenance information generation unit 422 stores the generated maintenance information in the maintenance information storage unit 434.

[0109] The maintenance work control unit 423 generates a maintenance plan. The maintenance plan is a plan for maintenance work to be performed when maintenance work is required for the water storage tank equipment. The maintenance plan includes information contained in the maintenance information, such as management information, whether maintenance work is necessary, urgency, target location, and content, as well as an estimate of costs such as the timing when the maintenance work should be carried out, the cost of parts if parts replacement is required, and the labor costs related to the maintenance work.

[0110] To carry out maintenance work on water storage facilities installed in public buildings, it is necessary to secure a budget. For example, in a typical local government, the budgeting process begins with each local government deciding on its financial management policy for the following fiscal year. Based on that policy, each department then formulates a business plan and submits a budget request. Subsequently, the finance department assesses and reviews the requests, and after confirmation by the mayor, a budget proposal is created. This budget proposal is then submitted to the assembly, where it is deliberated and voted on by the members before finally being approved. In this embodiment, a maintenance plan is generated that includes the timing and estimated costs of the maintenance work, thereby facilitating budgeting and supporting the implementation of maintenance work on water storage facilities at the appropriate time and with the appropriate content.

[0111] The maintenance work control unit 423 calculates an estimate of the costs related to maintenance work based on maintenance information. For example, based on the maintenance information, the maintenance work control unit 423 accesses a parts database that manages the prices and inventory of parts for water storage tank equipment to obtain information such as the cost of parts and availability of parts in cases where parts replacement is required. Also, if the maintenance work control unit 423 is to update (replace) water storage tank equipment during maintenance work, it accesses a database of businesses that manufacture water storage tank equipment on order to obtain an estimate of the number of days and costs required to produce water storage tank equipment of the same type as the water storage tank equipment to be replaced. Furthermore, the maintenance work control unit 423 accesses a work database that shows the work performance of businesses that can undertake maintenance work to obtain labor costs related to maintenance work. These parts database and work database may be provided within the water storage tank equipment maintenance support system or may be provided outside the water storage tank equipment maintenance support system.

[0112] Furthermore, the maintenance work control unit 423 may be configured to generate a maintenance plan that indicates the priority of maintenance work. For example, local governments often manage multiple water storage tank facilities, so it is conceivable that there may be cases where multiple water storage tank facilities require maintenance work at the same time. In such cases, indicating which water storage tank facility's maintenance work should be prioritized would allow the entire process, from budgeting to planning and execution of maintenance work, to proceed more smoothly. For example, the maintenance work control unit 423 first extracts water storage tank facilities that require maintenance work based on maintenance information. Next, the maintenance work control unit 423 classifies the extracted water storage tank facilities according to the client that manages the water storage tank facilities. The maintenance work control unit 423 may use property IDs for classification by client. Based on the classification results, the maintenance work control unit 423 extracts cases in which maintenance work is required for multiple water storage tank facilities managed by one client, and sets a maintenance work priority for each of the multiple water storage tank facilities included in the extracted cases. The maintenance work control unit 423 sets the maintenance work priority, for example, based on the urgency, target location, and content set in the maintenance information.

[0113] The maintenance status management device 400 displays the maintenance plan generated by the maintenance work control unit 423 on the client terminal 100 in response to access from the client terminal 100.

[0114] [Example of processing procedure: Processing to be carried out before maintenance is implemented] Referring to the sequence diagram in Figure 16, the processing procedure performed by the water tank equipment maintenance support system of this embodiment in relation to the implementation of maintenance work will be described. This sequence will be explained using as an example the case in which maintenance information is generated triggered by the creation of a cleaning report. However, it is not limited to this, and maintenance information may be generated triggered by inspection work being performed together with or in lieu of cleaning work, and by the creation of an inspection report.

[0115] Step S100: The worker terminal 300 creates a cleaning report and sends the created cleaning report to the maintenance status management device 400. For example, the worker terminal 300 takes a photo before cleaning and then performs the cleaning work. Once the cleaning work is complete, the worker terminal 300 takes a photo after cleaning, creates a cleaning report with the before and after photos attached, and uploads the created cleaning report to the maintenance status management device 400. Step S102: The maintenance status management device 400 checks the cleaning report notified from the worker terminal 300 and checks whether it is OK to report it to the client. For example, the maintenance status management device 400 checks, according to a pre-generated checklist, whether there are any omissions in filling in management information for the water storage tank equipment, whether before-cleaning photos and after-cleaning photos are attached, etc. Once the check is complete and it is confirmed that there are no deficiencies in the cleaning report, the maintenance status management device 400 sends the cleaning report to the client terminal 100. Step S104: The client terminal 100 receives the cleaning report notified by the maintenance status management device 400 and confirms its contents.

[0116] Step S106: The maintenance status management device 400 generates maintenance information based on the cleaning report notified from the worker terminal 300. The maintenance status management device 400 uses a trained model to determine whether maintenance work is necessary, and if maintenance work is necessary, it generates maintenance information by setting the urgency, target location, content, etc. of the maintenance work. Step S108: The maintenance status management device 400 generates a maintenance plan based on the maintenance information. The maintenance status management device 400 calculates an estimate of costs, including parts costs and labor costs, by accessing the parts database and the work database based on the maintenance information. The maintenance status management device 400 generates a maintenance plan including the estimated costs. The maintenance status management device 400 transmits the generated maintenance plan to the client terminal 100.

[0117] Step S110: The client terminal 100 receives the maintenance plan notified by the maintenance status management device 400 and confirms its contents. Step S112: The client terminal 100 reviews the maintenance plan and determines whether or not to carry out maintenance work on the water storage tank equipment. If it is determined that maintenance work will not be carried out, the process ends. On the other hand, if it is determined that maintenance work will be carried out, the client terminal 100 transmits a notification to the maintenance status management device 400 that maintenance work will be carried out. At this point, the client can proceed with budgeting for the costs of carrying out the maintenance work in accordance with the decision to carry out the maintenance work.

[0118] Step S114: The maintenance status management device 400 prepares an estimate in response to receiving a notification from the client terminal 100 that maintenance work will be carried out. Based on the maintenance plan, the maintenance status management device 400 prepares an estimate after reconfirming the status of the water storage tank equipment. The maintenance status management device 400 sends the prepared estimate to the client terminal 100.

[0119] Step S116: The client terminal 100 receives the quotation notified by the maintenance status management device 400 and confirms its contents. The client has already budgeted for the costs related to the maintenance work. Therefore, it is easy to secure the budget according to the quotation. Step S118: The client terminal 100 sends a notification to the maintenance status management device 400 requesting the execution of maintenance work. Step S120: The maintenance status management device 400 performs maintenance work in response to receiving a request to perform maintenance work from the client terminal 100.

[0120] In the sequence described above, the maintenance status management device 400 notifies the client terminal 100 of the cleaning report in step S102, and then notifies the client terminal 100 of the maintenance plan in step S108. However, it is not limited to this. The cleaning report and the maintenance plan may be notified to the client terminal 100 simultaneously or at the same time. Alternatively, the maintenance plan may be created independently of the timing of the creation of the cleaning report, and the created maintenance plan may be notified to the client terminal 100. If a maintenance plan is created independently of the timing of the cleaning report, for example, a worker may take photographs of the water storage tank equipment for the purpose of creating a maintenance plan, and these photographs are uploaded from the worker's terminal 300 to the maintenance status management device 400. The maintenance status management device 400 creates maintenance information and a maintenance plan based on the uploaded photographs. The maintenance status management device 400 then sends the created maintenance plan to the client's terminal 100.

[0121] As can be understood from the above explanation, the water storage tank equipment maintenance support system of the second embodiment further comprises a maintenance information generation unit 422. The maintenance information generation unit 422 generates maintenance information for the water storage tank equipment based on maintenance management information (cleaning reports, inspection reports, etc.). The maintenance information generation unit 422 transmits a maintenance plan, including the costs related to maintenance based on the maintenance information, to the client terminal 100. As a result, the water storage tank equipment maintenance support system of the second embodiment can transmit a maintenance plan to the client and assist in budgeting for maintenance costs.

[0122] The above explanation uses the example of determining the necessity of maintenance work based on photographs (still images) of the water storage tank equipment. However, it is not limited to this. The necessity of maintenance work may also be determined based on video footage of the inspection of the water storage tank equipment. In this case, the maintenance information generation unit 422 can determine the necessity of maintenance work based on the video footage in the same manner as when using photographs (still images) of the water storage tank equipment.

[0123] Furthermore, programs for realizing the functions of each device in the aforementioned water storage facility maintenance support system (client terminal 100, contractor terminal 200, worker terminal 300, maintenance status management device 400, map information server 500, etc.) may be recorded on a computer-readable recording medium, and the processing of each device in the aforementioned water storage facility maintenance support system may be performed by loading the program recorded on this recording medium into a computer system and executing it. Here, "loading the program recorded on the recording medium into a computer system and executing it" includes installing the program into the computer system. Here, "computer system" includes hardware such as the OS and peripheral devices. Also, "computer system" may include multiple computer devices connected via a network including communication lines such as the Internet, WAN, LAN, and dedicated lines. Also, "computer-readable recording medium" refers to portable media such as flexible disks, magneto-optical disks, ROMs, CD-ROMs, and storage devices such as hard disks built into the computer system. Thus, the recording medium storing the program may be a non-transient recording medium such as a CD-ROM. Also, the recording medium includes internal or external recording media that can be accessed from a distribution server for distributing the program. The program code stored on the distribution server's recording medium may be different from the program code in an executable format on the terminal device. In other words, as long as it can be downloaded from the distribution server and installed in an executable format on the terminal device, the format in which it is stored on the distribution server is irrelevant. Furthermore, the program may be divided into multiple parts, downloaded at different times and then combined on the terminal device, and each of the divided programs may be distributed by a different distribution server. In addition, "computer-readable recording medium" includes volatile memory (RAM) within computer systems that act as servers or clients when a program is transmitted over a network, which retains the program for a certain period of time. Moreover, the above program may be intended to implement only a part of the functions described above.Furthermore, the above-mentioned functions may be implemented in combination with programs already recorded in the computer system, such as so-called differential files (differential programs).
