The following embodiments are illustrative, and the material support system and method for supporting materials according to the present disclosure are not limited to the following embodiments. For example, the numerical values, shapes, materials, steps, order of steps, etc. shown in the following embodiments are merely examples, and various modifications can be made as long as there is no technical contradiction. Moreover, it is possible to combine one aspect with another aspect as long as there is no technical contradiction.

<1. Overview of material support system>
First, with reference to FIG. 1, an overview of a material support system in an embodiment of the present disclosure will be described. FIG. 1 illustrates a schematic configuration of a material support system in an embodiment of the present disclosure.

The material support system 1000 illustrated in FIG. 1 includes a management device 100 and a storage device to be described later. A terminal device 200 used at each of the plurality of stockpiling bases 300 is connected to the management device 100 via a network 400. The management device 100 may be connected to the storage device via the network 400 or may be connected to the storage device not via the network 400. In the illustrated example, seven terminal devices 200 used at seven stockpiling bases 300 are connected to the material support system 1000, but this is merely an example. The number of terminal devices 200 connected to the material support system 1000 may be several hundred or several thousand. Furthermore, the material support system 1000 may further include one or more edge computers from the viewpoint of reducing communication delays or distributing network loads.

Each stockpiling base 300 stores supplies in preparation for disasters. The types of supplies are not particularly limited, but include, for example, drinking water, food, clothing, and medicine. The material in an embodiment of the present disclosure is aluminum canned drinking water. Drinking water in aluminum cans can be stored for a longer period of time than drinking water in plastic bottles, so it is suitable for stockpiling at the storage base 300.

An example of the management device 100 is a cloud server, and an example of the storage device (see FIG. 13) is a cloud storage. The terminal device 200 is a computer used by a user at each stockpiling base 300. The management device 100 and the plurality of terminal devices 200 can communicate with each other via the network 400. The terminal device 200 illustrated in FIG. 1 is a mobile terminal such as a smartphone or a tablet computer, but is not limited thereto. The terminal device 200 may be a stationary computer such as a laptop computer or a desktop PC (personal computer). For example, by adopting a method of accessing the cloud system from a browser, users can use the material support system 1000 regardless of the type of device such as a smartphone or a tablet computer.

In this specification, a stockpiling base that has been affected by a natural disaster or the like will be referred to as a "disaster-stricken base", and a terminal device used at the disaster-stricken base will be referred to as a "disaster-stricken terminal device". In addition, stockpiling bases that can receive support requests from disaster-stricken bases and provide supplies to disaster-stricken bases are called "support base candidates," and at least one support base candidate is selected from one or more support base candidates. A support base candidate is called a "support base", and a terminal device used at the support base is called a "support side terminal device". FIG. 1 shows a disaster-affected terminal device 201 and a support-side terminal device 202 out of seven terminal devices 200, respectively. Furthermore, users who use disaster-affected terminal devices at disaster-affected bases are called "disaster victims," users who use terminal devices at support base candidates are called "support candidates," and users who use support-side terminal devices at support bases are called "support candidates." A user who does this may be called a "supporter". For example, the user may be an individual, a person in charge of a government, an organization, or a company, or a manager.

Information including the location (or address) of each of the plurality of stockpiling bases that stockpile supplies and the amount of stockpiled supplies stored at each of the plurality of stockpiling bases is called "stockpile information." Stockpiling information is stored in a storage device for each stockpiling base, with the location and stockpiled amount associated with each other. However, the stockpiling information may include, in addition to the location and stockpiled amount of supplies, further information such as past performance including the number of times support has been provided in the past.

The material support system according to the embodiment of the present disclosure can be linked to an existing system that is already operated by a municipality, town, or village, for example. Alternatively, material support systems enable cooperation between public bodies or municipalities. In addition, with the participation of the private sector, the government and the private sector can be connected through a material support system. Furthermore, multiple terminal devices used at multiple stockpiling bases located throughout Japan can be interconnected to the same material support system via a network.

FIG. 2 shows a diagram for explaining an overview of the material support system according to the embodiment of the present disclosure. In embodiments of the present disclosure, a manufacturer or distributor of a material (e.g., drinking water) may manage the material support system and may permit a purchaser to use the material support system, for example, upon request from a purchaser of the material. . Participation in the material support system is voluntary. When there is a shortage of supplies stockpiled at a disaster-affected base, a user who is a disaster victim can request support for supplies from other stockpiling bases using the disaster-affected terminal device. A support request signal is transmitted from the disaster victim terminal device to the management device through an operation by the disaster victim. The support request signal includes a disaster victim ID for identifying the disaster victim. The disaster victim ID is unique identification information assigned to each user. The user ID may be assigned in association with, for example, the serial number of the terminal device.

In an embodiment of the present disclosure, when a disaster victim makes a support request, the disaster victim notifies the material support system of the fact of the disaster and the amount of supplies (for example, drinking water) needed at the disaster site. Furthermore, when requesting assistance, a disaster victim may send a message containing information about supplies needed at the disaster site (for example, there is a shortage of food and clothing in addition to drinking water).

When a disaster victim requests assistance, the terminal device 200 may have a function that allows confirmation of the fact of the disaster, for example, the fact that a natural disaster has occurred as announced by the Japan Meteorological Agency. With this function, it is possible to appropriately prevent false support requests or reports, or incorrect entries.

When the material support system receives a support request from a disaster victim, it causes the management device to list support candidates based on the disaster victim ID. FIG. 2 shows an example of a list of support candidates including support candidates A and B as a result of listing based on the disaster victim ID. The management device inquires of the listed support candidates as to whether or not they can request support. In other words, the management device notifies the terminal device used by the support candidate that the support candidate has been selected as a support base candidate. The terminal device used by the support candidate is notified of the disaster-affected base's stockpile information, including the location of the disaster-stricken base and the amount of stockpiled supplies. Here, the stockpiling information of the disaster-stricken base does not include contact information of the disaster-stricken person. In the example shown in FIG. 2, support candidate A who received this notification replies to the management device that support with supplies is possible, and support candidate B who received this notification replies that support is not possible. The information is sent to the management device.

The management device receives answers from the support candidates and lists support candidates who can be supported from among the support candidates. The management device notifies the disaster victim terminal device of the listed results. The disaster victim uses the disaster victim terminal device to select at least one supporter from among the notified support candidates who can provide support, and notifies the management device of the selection result. The management device receives notification of the supporter selected by the disaster victim and determines that matching of the support request has been established. Thereafter, the management device transmits contact information of the supporter to the disaster victim terminal device, and transmits contact information of the disaster victim to the support terminal device. After matching is established, the disaster victim who has been notified of the contact information of the supporter will be able to contact the supporter, and the supporter who has been notified of the contact information of the disaster victim will be able to contact the disaster victim. It will be possible to contact you. Communication between disaster victims and supporters may be performed via the supply support system, or may be conducted without going through the supply support system (for example, via a telephone network).

In this way, according to the material support system according to the embodiment of the present disclosure, the contact information of disaster victims and supporters is not revealed until matching is established, so security and privacy are protected. After matching is established, users using the system can communicate smoothly with each other. For example, users may communicate with each other using a chat function or message sending/receiving function integrated into the system, email external to the system, or telephone.

<2. Details of the material support system＞
FIG. 3 shows a flowchart illustrating an example of the operation of the management device 100 from a request for material support until the support request is established. The management device 100 performs a step S100 of acquiring stockpiling information of a disaster-stricken base, a step S200 of determining one or more support base candidates that can provide supplies to the disaster-stricken base, and a step S200 of acquiring stockpiling information of a disaster-stricken base. An operation including step S300 of transmitting information to the disaster victim terminal device 201 is executed.

As described above, the stockpiling information of each stockpiling base 300 is stored in the storage device in association with the location and stockpiled amount of supplies. In embodiments of the present disclosure, customers who have purchased supplies may be permitted to use the system, as described above. Therefore, since the database is maintained based on the information of customers who have purchased goods, the reliability of the data is higher than when users are allowed to join voluntarily.

FIG. 6 illustrates a display screen 200A of the stored water database displayed on the terminal device 200. The display screen 200A may be a menu screen that includes items such as "administrator information," "internal water storage data," "request for assistance in times of disaster," "map display," and "tutorial." However, the illustrated menu screen is only an example. FIG. 7 illustrates a storage information display screen 200B displayed on the terminal device 200. The display screen 200B is displayed when the item "Internal stored water data" on the menu screen shown in FIG. 6 is selected. The display screen 200B includes information on the amount of stored water (number of cases) and address of each of the storage bases 300A to 300C among the plurality of storage bases 300 managed by the same administrator. The terminal device 200 in the illustrated example has a function of displaying or hiding an address. The stockpiling information displayed on the display screen 200B may be updated, for example, on a daily or weekly basis.

(Step S100)
In response to a request for support for supplies sent from the disaster-side terminal device 201 of the disaster-affected base, which is the disaster-stricken stockpiling base among the plurality of stockpiling bases 300, the management device 100 accesses the storage device and stores the stockpiles at the disaster-stricken base. Get information. FIG. 8 illustrates a display screen 200C for requesting assistance in the event of a disaster, which is displayed on the terminal device 200. The display screen 200C is displayed when the item "Request for support in case of disaster" is selected on the menu screen shown in FIG. 6. According to an example of such a display screen, for example, the administrator selects a stockpiling base that requires supplies by pressing the support request button displayed on the display screen 200C, and requests support to the stockpiling base. can be easily performed. Further, as described above, the disaster victim terminal device 201 that receives input from the administrator notifies the material support system of, for example, the fact of a disaster and the amount of materials needed at the disaster site.

(Step S200)
Based on the stockpiling information of the disaster-stricken base, the management device 100 determines one or more support base candidates that can provide supplies to the disaster-stricken base from among the plurality of stockpiling bases 300 other than the disaster-stricken base.

FIG. 4 shows a more detailed flowchart of the processing included in step S200. The processing procedure illustrated in FIG. 4 includes processing in steps S210 to S270. In steps S210 to S250, the management device 100 extracts preliminary candidates for a plurality of support bases while updating the extraction conditions determined based on the storage information of the disaster-stricken base.

In step S210, the management device 100 can calculate an evaluation score as an extraction condition. For example, the management device 100 calculates an evaluation score based on stockpiling information of a disaster-affected base and stockpiling information of a plurality of stockpiling bases 300 other than the disaster-stricken base, and extracts preliminary candidates for a plurality of support bases based on the evaluation score. do. The management device 100 can calculate the distance from the support base to the disaster-stricken base based on the stockpiled information, for example, as a Euclidean distance or a Manhattan distance between coordinate points on a map. The management device 100 can calculate the evaluation score by further considering at least one of the transportation time, transportation cost, and transportation network of the supplies from the support base to the disaster-stricken base. This can be achieved, for example, by introducing optimal transport theory into the calculation of the evaluation score. Therefore, the process in step S230 may include solving the optimal transportation problem using, for example, a genetic algorithm. Details of the optimal transport theory and examples of algorithms are described in JP 2019-133323A and US Patent Application Publication No. 2020/0065759. All disclosures of JP 2019-133323 A and US Patent Application Publication No. 2020/0065759 are incorporated herein by reference. The management device 100 may calculate the evaluation score by further considering the recovery time of the stockpiled amount of supplies at the stockpiling base 300 and the like.

The evaluation score can be calculated by taking into account the type of road (national highway, prefectural road, private road, etc.) that connects the disaster-stricken base and the support base. This allows the management device 100 to present candidates for support bases that can smoothly respond to disruptions in the transportation network, making it possible to increase the resilience of the system in the event of a disaster.

In step S220, if the management device 100 cannot extract pre-candidates for multiple support bases, it updates the extraction conditions, that is, the evaluation scores (step S230), and uses the updated extraction conditions to extract multiple support bases. Extract preliminary candidates for bases. The extraction conditions, that is, the evaluation scores are updated so that the conditions are relaxed. If the management device 100 is able to extract preliminary candidates for a plurality of support bases, the process advances to the next step S240. If the management device 100 is unable to extract pre-candidates for a plurality of support bases, it repeatedly executes the processes of steps S210 to S230 until it can extract pre-candidates for a plurality of support bases.

In step S240, the management device 100 notifies the terminal device 200 of the stockpiling base 300 indicated by the location of each of the pre-candidates of the plurality of support bases that the stockpiling base 300 has been designated as a pre-candidate for the support base. The user who uses the terminal device 200 that has received this notification recognizes that the stockpiling base 300 has been selected as a preliminary support base candidate, and determines whether or not to accept the support request. The user transmits whether or not to accept the support request from the terminal device 200 to the management device 100.

FIG. 9 illustrates a display screen 200D that is displayed on the terminal device 200 and notifies that the user has been selected as a support base candidate. The terminal device 200 displays the display screen 200D in response to a signal sent from the management device 100 notifying that the terminal device 200 has been selected as a support base candidate. The user can press the "Support Allowed" button to accept the support request from the disaster-affected base that requires support displayed on the display screen 200D, and press the "Support Not Allowed" button to reject the support request. can. In this way, by displaying on the terminal device 200 that the support request has been received, the user can instantly reply to the management device 100 as to whether or not the support request has been accepted. Furthermore, when a disaster victim makes a support request, the amount of supplies and period required by the disaster-affected base may be input into the disaster-affected terminal device 201. Such information is transmitted from the disaster victim terminal device 201 to the management device 100, and is notified from the management device 100 to the terminal device 200 used as a support base candidate. A user who has received a support request can use information on the amount and period of supplies required by the disaster-stricken base as material for determining whether to accept the support request.

In step S250, the management device 100 receives an acceptance notification indicating whether the support request can be accepted, which is transmitted from the terminal device 200 in response to the notification of the support base candidate. If the acceptance notifications that can be transmitted from one or more terminal devices 200 include at least one notification indicating that the support request can be accepted, the process proceeds to the next step S260. On the other hand, if the acceptance notifications that can be transmitted from one or more terminal devices do not include any notification indicating that the support request can be accepted, the process returns to step S230. The management device 100 relaxes the extraction conditions and tries again to extract preliminary candidates for the plurality of support bases using the relaxed extraction conditions. (Step S210).

In step S260, the management device 100 extracts one or more support base candidates from among the plurality of support base candidates based on the information on whether the support request is accepted or not, which is indicated by the acceptance notice. In other words, the management device 100 selects one or more stockpiling bases 300 that use the terminal device that has transmitted the notification indicating acceptance of the support request from among the plurality of preliminary support base candidates as one or more support base candidates. Extract as. For example, assume that the management device 100 has extracted 10 bases as preliminary candidates of the plurality of support bases in step S210. In this case, when the management device 100 receives a notification indicating that the support request can be accepted from each terminal device 200 used at three of the ten bases, the management device 100 selects the three bases that are among the preliminary candidates for the ten bases. Determined as a candidate for a support base.

In step S270, the management device 100 transmits stockpiling information including the location and stockpiled amount of supplies of one or more support base candidates belonging to the plurality of preliminary support base candidates to the disaster-affected terminal device. FIG. 10 illustrates a support base candidate display screen 200E displayed on the terminal device 200. In this example, a user who is a disaster victim can select one or more support bases from support base candidates 301, 303, and 305 by pressing the enter button.

FIG. 11 illustrates a display screen 200F that is displayed on the terminal device 200 and shows the positions of support base candidates on a map. The terminal device 200 may display a display screen 200F showing the location of the support base candidate on the map. Furthermore, by placing the arrow cursor on one of the support base candidates on the map, the terminal device 200 may display the stockpiling information 200G for that stockpiling base. The user can intuitively recognize the location of the stockpiling base while checking the amount of supplies stockpiled at the stockpiling base on the map. Furthermore, in this example, the amount of stockpiled supplies (for example, the number of cases of drinking water) is clearly indicated on the map by the icon indicating the location of the stockpiling base. Since the stockpiled amount is displayed on the map, it can be easy to grasp the stockpiled status of nearby supplies.

(Step S300)
The management device 100 transmits support information including storage information of at least one support base determined from one or more support base candidates to the disaster victim terminal device 201. FIG. 5 shows a more detailed flowchart of the processing included in step S300. The processing procedure illustrated in FIG. 5 includes processing in steps S310 to S330.

In step S310, the management device 100 causes the disaster-affected terminal device 201 to output the storage information of the support base candidates, and allows the user who is the victim of the disaster-stricken base to select a support base from among one or more support base candidates. .

In step S320, if the support base is selected by the user of the disaster-stricken base, the process proceeds to the next step S330. The user is not limited to one support base, and may select multiple support bases. If no support base is selected by the user of the disaster-affected base, that is, if the support candidate desired by the disaster victim is not found, the process returns to step S250, and the management device 100 relaxes the extraction conditions. Extraction of pre-candidates for multiple support bases is attempted again using the relaxed extraction conditions (see FIG. 4). The management device 100 can quickly determine preliminary candidates for the next support base, for example, by relaxing conditions such as the distance from the disaster-affected base to the support base candidate and the stocked amount of supplies.

In step S330, the management device 100 transmits the support information of at least one support base selected by the user of the disaster-stricken base to the disaster-stricken side terminal device 201, and transmits the contact information of the disaster-stricken base to the support side of the support base. It is transmitted to the terminal device 202. Here, the stockpiling information does not include contact information of the stockpiling base 300, and the support information includes contact information of the support base. As a result, after matching is established, the disaster victim who has been notified of the contact information of the supporter will be able to contact the supporter, and the supporter who has been notified of the contact information of the disaster victim will be able to contact the supporter. It will be possible to contact. Communication between disaster victims and supporters may be performed via the material support system, or may be performed, for example, by telephone or by e-mail external to the system. After a match is established, a chat is established between the disaster victim and the support person, so that even if communication becomes unstable, the minimum information such as the location where supplies can be delivered can be exchanged. This is desirable.

FIG. 12 shows a flowchart of another example of the operation of the management device 100 from a request for material support until the support request is established. Furthermore, when the management device 100 decides to support supplies from the support base to the disaster-stricken base, the management device 100 orders supplies in an amount determined according to the amount of supplies that the disaster-stricken base receives support, with the location of the support base as the delivery destination. The process may include step S400. For example, the management device 100 may have a function of prompting the disaster victim to return the supplies to the supporter after a predetermined period (for example, 90 days) has passed after the matching is established. Thereby, the management device 100 can appropriately manage the inventory of supplies at each stockpiling base 300.

FIG. 13 shows an example of a display screen displayed on the disaster victim terminal device 201 after matching is established. The display screen in the example shown in FIG. 13 includes stock information 200H of the support base, the amount of supplies requested for support 200I, and a message 200J regarding ordering. The support base stock information 200H includes the support base representative and contact information. Furthermore, as a thank you for the support, a message 200J may be displayed urging the support base that is the support source to order supplies. If the user who is a disaster victim agrees to order the supplies, he or she can press the OK button to order the supplies. However, it is not necessary to display a message prompting the ordering of supplies, and the management device 100 may automatically order the supplies after matching is established.

After matching is established, messages may be exchanged in a chat format between the disaster victim and the supporter. FIG. 13 shows a chat box 200K for posting messages. This allows users to go back and check their messages and check their history. Further, even after matching is established, communication between disaster victims and supporters can be easily continued.

FIG. 14 shows an example of a display screen displayed on the support side terminal device 202 after matching is established. The display screen in the example shown in FIG. 14 includes stockpile information 200M of the disaster-stricken base and a message 200N of the expected delivery date of supplies ordered by disaster victims. By checking the display screen, the supporter can confirm the representative and contact information of the disaster-affected base, and also know that support supplies will be ordered from the support destination. The display screen displayed on the support side terminal device 202 may also include a chat box 200K for posting messages, similarly to the disaster victim side terminal device 201.

In this way, according to the material support system according to the embodiment of the present disclosure, the contact information of disaster victims and supporters is not revealed until matching is established, so security and privacy are protected. After a match is established, users using the system can communicate smoothly using, for example, the chat function or message sending/receiving function integrated into the system, e-mails outside the system, or telephone calls. Become. In addition, by sending and receiving a minimum amount of support information in a database, that is, stockpiled information, between disaster victims and supporters, it is possible for disaster victims to request support even if, for example, the communication network bandwidth drops during a disaster. I can do it.

FIG. 15 shows a flowchart of still another example of the operation of the management device 100 from a request for material support until the support request is established. The management device 100 may further include step S500 of making a delivery plan for delivering the supplies ordered by the disaster victim to the support base and arranging the delivery. The management device 100 can optimize the delivery plan using various known algorithms. Alternatively, if the land transportation network is unavailable due to a disaster, the management device 100 may plan the delivery of supplies using drones.

In the above example, the operation of the management device 100 during a disaster was mainly explained, but the management device 100 also discloses information on the approximate location of the stockpiling base and the stockpiled amount of supplies to the user even during normal times, or may be shared with other users. With this, for example, it is possible to grasp the stockpiled amount of supplies at stockpiling bases in other local governments or municipalities. Further, it is preferable that a backup center made up of a plurality of bases backs up data (stockpiling information of each stockpiling base) stored in a storage device in real time. This makes it possible to increase resilience during disasters.

In the above-mentioned example, the disaster victim selected at least one support person from among the notified support candidates who could provide support using the disaster victim terminal device 201, but the embodiment of the present disclosure is limited to this. Not done. The management device 100 may automatically determine a supporter from among possible support candidates. For example, the management device 100 may determine the stockpiling base with the highest evaluation score as the support base.

Access to the system in an emergency can be made easier by displaying the URL or two-dimensional barcode for accessing the supply support system on the supply container (for example, a can in the case of canned drinking water) or the cardboard case. It can be. In addition, the management device 100 notifies the terminal device 200 to perform an inventory every year, for example, after purchasing supplies, thereby prompting the manager or person in charge of each stockpiling base to check the inventory of supplies during normal times. Good too.

The management device 100 can manage the expiration dates of materials stockpiled at each stockpiling base. For example, the management device 100 may notify the manager or person in charge of the stockpiling base to replace or replenish the supplies when half of the expiration date of the supplies has passed. This will give the manager or person in charge an incentive to actively support supplies, and as a result, it is expected to have the effect of fostering communication between regions and resetting expiration dates.

The material support system 1000 according to the embodiment of the present disclosure may receive a plurality of support requests from a plurality of disaster-stricken bases located in an area where a disaster has occurred, for example. Even in that case, the management device 100 makes it possible to support supplies from a plurality of support bases to a plurality of disaster-stricken bases by, for example, introducing optimal transportation theory into the calculation of the evaluation score.
