[0028] <Processing> <<Processing to support user-initiated stockpiling>> Next, with reference to Figures 4 to 6, an example of the process by which the information processing device 10 according to the embodiment supports user stockpiling will be described. Figure 4 is a flowchart of an example of the process by which the information processing device 10 according to the embodiment supports user stockpiling. Figure 5 is a diagram showing an example of the display screen for recommended stockpiled items according to the embodiment. Figure 6 is a diagram showing an example of the information stored in the user stockpiling DB (database) 601 according to the embodiment. Note that the process in Figure 4 may be executed, for example, when a specific operation is performed on the user terminal 20.

[0029] In step S101, the control unit 12 accepts a login from the user terminal 20. Here, the control unit 12 may authenticate the user using, for example, the user's My Number Card ID and password received from the user terminal 20. The login operation on the user terminal 20 may be performed on an application installed on the user terminal 20, or on the display screen of a specific website.

[0030] Next, the acquisition unit 11 acquires the user's personal information from the local government server 30, etc. (step S102). Here, the acquisition unit 11 may, for example, acquire personal information such as address, age, gender, and chronic illness for the logged-in user (the person themselves, for example, the head of the household) and each other user living with the logged-in user (cohabitants).

[0031] Next, the control unit 12 displays a recommendation list on the user terminal 20 showing the quantity of each stockpile that it recommends the user stockpile, calculated based on the user's personal information (e.g., age, gender, and pre-existing medical conditions, etc.) (step S103). Here, the control unit 12 may, for example, use information from a table specified by the local government where the user resides to calculate the total quantity of each stockpile according to the age, gender, and pre-existing medical conditions, etc., of the user and each cohabitant. The control unit 12 may then display this information on the user terminal 20 as shown in the display screen 501 of Figure 5.

[0032] In the example shown in Figure 5, the recommended list display screen 501 shows the recommended stockpiles and quantities for the user in each area 511 to 513. When the purchase button 521 is pressed, the process proceeds as follows.

[0033] Furthermore, the control unit 12 may generate a recommendation list based, for example, on the user's personal information and the quantity of each stockpiled item stored in a warehouse associated with the specific area where the user resides. This can encourage the user to stockpile items that are not sufficiently stockpiled in warehouses such as evacuation centers.

[0034] Next, the control unit 12 sends a request to the server of an e-commerce (EC) business operator or similar to purchase the quantity of each stockpiled item specified by the user and deliver it to the user's home (step S104). As a result, each stockpiled item specified by the user is delivered to the user's home in the quantity specified by the user and stored there.

[0035] Next, when the purchase process is completed, the control unit 12 records the items and quantities purchased by the user in the user stockpiling DB 601 based on the user's purchase history of stockpiling items (step S105). This makes it possible to obtain, for example, the quantity of each stockpiling item stockpiled by each user based on the purchase history of each user's stockpiling items.

[0036] In the example shown in Figure 6, the User Stockpile DB 601 records the address, personal information of the user and their cohabitants, the quantity of each stockpile, and the expiration date, all associated with the User ID. The User ID is the identification information of the logged-in user. The quantity of each stockpile is the quantity of each stockpile purchased by the user in step S104. The expiration date of each stockpile is the expiration date of each stockpile purchased by the user in step S104. The expiration date information may be obtained, for example, from the server of the e-commerce business that sold the stockpile during step S104. The information in the User Stockpile DB 601 may be recorded in the internal storage device of the Information Processing Device 10, or in an external storage device (for example, the local government server 30). The information in the User Stockpile DB 601 may be updated in response to operations by a user who has logged into the Information Processing Device 10 from the user terminal 20.

[0037] (Example of an alert for the expiration date) The control unit 12 may warn each user about the expiration date of their stockpiled goods based on their purchase history. This can prompt users to consume food items that are nearing their expiration date, for example. In this case, the control unit 12 may send a message to the user terminal 20 of a specific user indicating that the difference between the expiration date of a stockpiled item stored by that user, as recorded in the user stockpiling DB 601, and the current date and time falls below a threshold.

[0038] Furthermore, if the expiration date of stockpiled goods held by a specific user has passed, the control unit 12 may send contact information to the user terminal 20 of that specific user for handling such stockpiled goods, such as discount sales, domestic or international donations, or provision for volunteer activities. This allows for the effective utilization of stockpiled goods that have passed their expiration date, for example, from the perspective of SDGs (Sustainable Development Goals).

[0039] <<Processing to support stockpiling by local governments>> Next, with reference to Figures 7 and 8, an example of the processing by the information processing device 10 according to the embodiment that supports stockpiling by local governments will be described. Figure 7 is a flowchart of an example of the processing by the information processing device 10 according to the embodiment that supports stockpiling by local governments. This figure shows an example of information stored in the evacuation center stockpiling DB (database) 801 according to the embodiment.

[0040] In step S201, the acquisition unit 11 acquires information indicating the quantity of each stockpiled item required for each user residing in a specific area, information indicating the quantity of each stockpiled item stored by each user, and information indicating the quantity of each stockpiled item stored in a warehouse associated with the specific area.

[0041] Here, the acquisition unit 11 may acquire the corresponding area of ​​the evacuation shelter to be processed from the evacuation shelter stockpiling DB 801 shown in Figure 8. In the example in Figure 8, the evacuation shelter stockpiling DB 801 records the address, corresponding area, quantity of each stockpiled item, and expiration date, associated with the evacuation shelter ID. The evacuation shelter ID is the identification information of each evacuation shelter. The corresponding area is the area where residents who are expected to use the evacuation shelter reside. The information on the quantity and expiration date of each stockpiled item may be registered in advance by, for example, the warehouse manager. The information in the evacuation shelter stockpiling DB 801 may be recorded in the internal storage device of the information processing device 10, or in an external storage device (for example, the local government server 30). The information in the evacuation shelter stockpiling DB 801 may be updated in response to an operation by the evacuation shelter administrator who has logged into the information processing device 10.

[0042] The acquisition unit 11 may then refer to the user stockpile DB 601 in Figure 6 and acquire personal information of each user, including the user themselves and their cohabitants, whose address is located within the service area of ​​the evacuation center being processed. The control unit 12 may then use, for example, information from a table designated by the local government to calculate the total quantity of each stockpile item according to the age, gender, and pre-existing medical conditions of each user, including the user themselves and their cohabitants, in each household whose address is located within the service area. The control unit 12 may then use the calculated value as the required quantity of each stockpile item for each user residing in the specific area.

[0043] Furthermore, the acquisition unit 11 may refer to the user stockpile DB 601 in Figure 6, which records stockpiles purchased based on a recommended list tailored to each user's personal information, and acquire the quantity of each stockpiled item stored by each user residing in the area covered by the evacuation shelter being processed. Here, the acquisition unit 11 may, for example, acquire the quantity of stockpiles purchased based on a recommended list tailored to each user's personal information that have not yet expired (the current date and time is before the expiration date). The acquisition unit 11 may also refer to the evacuation shelter stockpile DB 801 in Figure 8 and acquire the quantity of each stockpiled item stored in a warehouse associated with the evacuation shelter being processed.

[0044] Next, the control unit 12 outputs information based on the quantity (shortfall) obtained by subtracting the total quantity stockpiled by each user and the quantity stockpiled by the warehouse from the quantity required for each user (step S202). Here, the control unit 12 may calculate the shortfall F using the following equation (1). F = Q1 - (Q2 + Q3) ... (1)

[0045] Here, Q1 is the quantity of each stockpile required for each user residing in a specific area. Q2 is the total quantity of each stockpile stockpiled by each user residing in a specific area. Q3 is the quantity of each stockpile stockpiled in warehouses associated with a specific area.

[0046] The control unit 12 may send information indicating the shortage to the local government server 30. This allows, for example, local governments to consider purchasing stockpiled items for each evacuation center. The control unit 12 may also send a message to at least one of the local governments in a specific region and each user urging them to purchase a particular stockpiled item if the shortage exceeds a threshold. This allows, for example, local governments and users to consider purchasing stockpiled items that are expected to be in short supply at evacuation centers. In this case, the control unit 12 may refer to the user stockpiling DB 601 and send a message to the user terminal 20 of users who do not stockpile a particular stockpiled item urging them to purchase that item. This allows, for example, to more effectively encourage users who do not stockpile items to do so.

[0047] (Example of reporting stockpiled supplies to the local government in the event of a disaster) The control unit 12 may, in the event of a disaster (e.g., earthquake, tsunami, fire, etc.), transmit information to the local government server 30 indicating the address of each user and the quantity of each stockpiled item held by each user. This allows the local government, for example, to understand the stockpiling status of each user. In this case, the control unit 12 may, for example, receive a notification from the Japan Meteorological Agency's server that a disaster has occurred in a specific area. The control unit 12 may then transmit information regarding addresses and stockpiled items recorded in the user stockpiling DB 601 to the local government server 30.

[0048] (An example of promoting peer-to-peer support for stockpiling supplies) In the event of a disaster, the control unit 12 may notify the second user, who has stockpiled the second set of stockpiled goods, of a request to exchange the first set of stockpiled goods owned by the first user for the second set of stockpiled goods owned by another user. This allows, for example, residents to exchange and procure any insufficient stockpiled goods among themselves. In this case, the control unit 12 may, for example, receive a notification from the Japan Meteorological Agency's server that a disaster has occurred in a specific area. The control unit 12 may then receive a request from the first user's user terminal 20 to exchange the first set of stockpiled goods for the second set of stockpiled goods. The control unit 12 may then refer to the user stockpiled goods DB 601 and notify the second user's user terminal 20, who has stockpiled the second set of stockpiled goods, of a message proposing the exchange of the first set of stockpiled goods for the second set of stockpiled goods. If the second user's user terminal 20 accepts the request, the control unit 12 may then notify the second user's user terminal 20 of the first user's contact information (for example, phone number or email address).

[0049] <Other> This document examines the case where local governments stockpile necessary supplies based on the assumption that residents do not have their own reserves. In this case, the supplies that residents have voluntarily stockpiled may be left over at evacuation centers, exceeding their expiration dates and becoming wasteful. This disclosure allows for understanding residents' stockpiling status and calculating appropriate stockpiling quantities.

[0050] <Variation> The information processing device 10 may be a device contained in a single enclosure, but the information processing device 10 of this disclosure is not limited to this. Each part of the information processing device 10 may be implemented by cloud computing, for example, consisting of one or more computers. The information processing device 10 and the local government server 30 may be configured as an integrated information processing device. Furthermore, the local government server 30 may execute at least some of the processing of each functional part of the information processing device 10. Such information processing devices 10 are also included as examples of "information processing devices" in this disclosure.
