Summary of the Invention

Problems to be Solved by the Invention

[0005] In the method described in Patent Document 1, if a match is made between the requested item and the item to be provided in the provision determination, and at least one of the requested item or the item to be provided is eligible for permission, a request notification is sent to the supporter. Therefore, according to the method described in Patent Document 1, appropriate goods are provided to the requester, and the possibility of inappropriate goods being provided to the requester is reduced.

[0006] In response to disasters, shelters are sometimes opened with supplies provided not by public institutions, but by ordinary citizens. In such cases, ordinary citizens often provide supplies to shelters based on their own subjective opinions, without checking whether there is a surplus or shortage of supplies. It is difficult to predict the type and quantity of supplies provided by ordinary citizens. In the method described in Patent Document 1, supplies cannot be provided to shelters unless the needs of the shelters match those of the supporters. Therefore, in the method described in Patent Document 1, supporters could not provide the supplies they wanted to give to shelters unless they were specifically requested by the shelters.

[0007] The purpose of this disclosure is to provide an information display device, etc., that can appropriately present to supporters the evacuation centers to which they can provide the supplies they wish to donate. [Means for solving the problem]

[0008] An information display device according to one aspect of this disclosure includes an information acquisition unit that acquires evacuation information including the number of evacuees at each evacuation center and material information including the number of supplies at each evacuation center; a prediction unit that predicts surplus / shortage information regarding the surplus / shortage of supplies at each evacuation center according to the evacuation information and material information; and an output unit that outputs the predicted surplus / shortage information.

[0009] In one aspect of the information presentation method of this disclosure, evacuation information including the number of evacuees at each evacuation center and material information including the number of supplies at each evacuation center are acquired, and information regarding surplus or shortage of supplies at each evacuation center is predicted based on the evacuation information and material information, and the predicted surplus or shortage information is output.

[0010] A program in one aspect of this disclosure causes a computer to perform the following processes: acquiring and outputting evacuation information including the number of evacuees at each evacuation center and material information including the number of supplies at each evacuation center; predicting and outputting information regarding the surplus or shortage of supplies at each evacuation center based on the evacuation information and material information; and outputting the predicted surplus or shortage information. [Effects of the Invention]

[0011] According to this disclosure, it will be possible to provide information display devices, etc., that can appropriately show supporters the evacuation centers to which they wish to provide the supplies they wish to donate. [Brief explanation of the drawing]

Embodiments for Carrying Out the Invention

[0013] The embodiments for carrying out the present invention will be described below with reference to the drawings. However, the embodiments described below have technically preferred limitations for carrying out the present invention, but the scope of the invention is not limited thereto. In all the figures used in the description of the embodiments below, the same parts are denoted by the same reference numerals unless there is a particular reason not to. Also, in the embodiments below, repeated explanations of similar configurations and operations may be omitted.

[0014] (First embodiment) First, the information display device according to the first embodiment will be described with reference to the drawings. The information display device of this embodiment displays information regarding the surplus or shortage of supplies at a managed evacuation center based on information about evacuees and supplies at the managed evacuation center. If multiple managed evacuation centers are established, the information display device of this embodiment displays information regarding the surplus or shortage of supplies for each evacuation center. For example, the information display device of this embodiment is built on a server or in the cloud. For example, the information display device of this embodiment may be built as a dedicated terminal device.

[0015] (composition) Figure 1 is a block diagram showing an example of the configuration of the information display device 10 according to this embodiment. The information display device 10 includes an information acquisition unit 11, a prediction unit 12, and an output unit 13.

[0016] The information acquisition unit 11 acquires evacuation information for each evacuation center. The evacuation information includes the number of evacuees. The evacuee information may also include the gender of the evacuees, the number of children, the number of infants, the number of elderly people, the number of people with disabilities, etc.

[0017] Figure 2 is a conceptual diagram illustrating an example of registering evacuee information for those who have taken refuge in a shelter. A terminal device 111, an input device 112, and a surveillance camera 113 are installed in the shelter. For example, the terminal device 111, the input device 112, and the surveillance camera 113 are placed at the entrance of the shelter. The terminal device 111, the input device 112, and the surveillance camera 113 are used to register evacuee information for those who have taken refuge in the shelter. For example, the terminal device 111, the input device 112, and the surveillance camera 113 may be placed inside the shelter. In this case, the terminal device 111, the input device 112, and the surveillance camera 113 can be used not only for registering evacuees who have taken refuge in the shelter, but also for managing evacuees in the shelter.

[0018] Figure 2 shows a management device 100 for managing evacuee information in an evacuation center. For example, the management device 100 is configured as a dedicated terminal installed in each evacuation center. For example, the management device 100 may be configured on a server or in the cloud. The management device 100 is connected to a terminal device 111, an input device 112, and a surveillance camera 113. The management device 100 is also connected to an information display device 10.

[0019] The management device 100 outputs the registered evacuation information to the information display device 10. The timing of the output of evacuation information to the information display device 10 can be set arbitrarily. For example, in response to the input of new evacuation information, the management device 100 outputs the registered evacuation information to the information display device 10. For example, in response to the update of registered evacuation information, the management device 100 outputs the registered evacuation information to the information display device 10. For example, at a pre-set timing, the management device 100 outputs the registered evacuation information to the information display device 10.

[0020] For example, the management device 100 registers evacuation information entered by local government officials via the terminal device 111. For example, the terminal device 111 may have a function to read codes for accessing personal information attached to evacuees' identification cards, etc. Examples of such codes include matrix-type two-dimensional codes such as QR (Quick Response) codes (registered trademark) and stack-type one-dimensional codes such as barcodes. Having a code reading function simplifies the process of registering evacuees with the management device 100 and the process of managing evacuees using the management device 100.

[0021] For example, evacuation information entered by evacuees via an input device 112 installed for evacuation shelter management is registered in the management device 100. In the example in Figure 2, the input device 112 has a touch panel. For example, the input device 112 may have a function to read a code for accessing personal information attached to an evacuee's identification card, etc.

[0022] For example, the management device 100 may identify individuals extracted from images captured by surveillance cameras 113 installed in the evacuation center using facial recognition and register the identified information. Facial recognition can also be used to monitor the status of evacuees inside the evacuation center. Alternatively, the management device 100 may identify evacuees based on their gait patterns extracted from images captured by surveillance cameras 113.

[0023] Personal authentication using codes attached to identification documents allows an individual to be identified by possessing that identification document. However, personal authentication using codes carries the risk of impersonation by possessing another person's identification document. Therefore, multiple personal authentication technologies may be combined to prevent impersonation by evacuees. For example, biometric authentication based on physical characteristics such as face, iris, fingerprint, vein, palm print, or gait may be used as a personal authentication technology to identify evacuees. For example, knowledge authentication combining a personal identifier and a password may be used as a personal authentication technology to identify evacuees. For example, lifestyle authentication based on behavioral patterns in evacuation shelters may be used as a personal authentication technology to identify evacuees.

[0024] Furthermore, the information acquisition unit 11 acquires information on supplies for each evacuation center. For example, supplies include water, food, clothing, bedding, bathing supplies, cleaning supplies, daily necessities, electrical appliances, entertainment items, luxury goods, etc. For example, supplies include cardboard boxes, blue tarpaulins, plastic bags, etc. For example, supplies include portable toilets, diapers, etc. Supplies may also include VR (Virtual Reality) goggles, ashtrays, supplies for people with disabilities, batteries, etc. For example, the information acquisition unit 11 may also include services in addition to supplies. For example, services include various construction work such as electrical work, gas work, water work, and air conditioning work, as well as repairs of various supplies. For example, services include barbering, beauty treatments, massages, etc. Supplies and services together are sometimes referred to as the items to be provided. In the following, when the term "supplies" is used, it includes services.

[0025] The quantity of supplies for each evacuation center is registered in the management device 100. For example, the quantity of supplies is registered in the management device 100 by local government officials via the terminal device 111. For example, the quantity of supplies is registered in the management device 100 by evacuees via the input device 112. For example, the quantity of supplies is registered in the management device 100 based on images captured by the surveillance camera 113. There are no particular limitations on the method of registering the quantity of supplies for each evacuation center in the management device 100.

[0026] The management device 100 outputs supply information, including the quantity of supplies for each evacuation center, to the information display device 10. The timing of the output of supply information to the information display device 10 can be set arbitrarily. For example, in response to the input of new supply information, the management device 100 outputs the registered supply information to the information display device 10. For example, in response to the update of registered supply information, the management device 100 outputs the registered supply information to the information display device 10. For example, at a pre-set timing, the management device 100 outputs the registered supply information to the information display device 10. The management device 100 may also output evacuation information and supply information to the information display device 10 at the same time.

[0027] The prediction unit 12 acquires evacuation information and supply information for each evacuation center from the information acquisition unit 11. Based on the acquired evacuation information and supply information, the prediction unit 12 predicts the surplus or shortage of supplies for each evacuation center. The prediction unit 12 outputs information regarding the surplus or shortage of supplies for each evacuation center (also called surplus / shortage information). For example, the surplus / shortage information includes information indicating whether the number of supplies is insufficient, sufficient, or in excess. For example, the indicators for surplus / shortage information are insufficient, sufficient, and excess. For example, the surplus / shortage information indicates the current surplus or shortage of supplies. For example, the surplus / shortage information may indicate future surplus or shortage of supplies. The surplus / shortage information may include information on the surplus or shortage of supplies in similar disasters that have occurred in the past. For example, similar disasters that have occurred in the past may have occurred in the same region or in different regions.

[0028] The prediction unit 12 predicts the surplus or shortage of supplies based on the current number of supplies. For example, the prediction unit 12 may predict the surplus or shortage of supplies based on information on surplus or shortage of supplies in similar disasters that have occurred in the past. For example, two thresholds (first threshold, second threshold) are set for the number of supplies. The first threshold is a threshold (quantity) for determining whether there is a shortage or sufficiency of supplies. The second threshold is a threshold (quantity) for determining whether there is a sufficiency or surplus of supplies. If the number of supplies falls below the first threshold, there is a shortage of supplies. If the number of supplies is equal to or greater than the first threshold and less than or equal to the second threshold, there is a sufficiency of supplies. If the number of supplies exceeds the second threshold, there is a surplus of supplies. However, the number of thresholds set for the number of supplies is not limited to two. The thresholds set for the number of supplies should be set according to the number of indicators set for the number of supplies.

[0029] The prediction unit 12 may predict the supply indicator (shortage, sufficient, surplus) according to the amount of consumption corresponding to the number of evacuees sheltering in the shelter. For example, the prediction unit 12 calculates the amount of consumption of supplies by multiplying the number of evacuees housed in the shelter by the amount of supplies needed for each evacuee. The prediction unit 12 calculates the current surplus or shortage of supplies by subtracting the amount of consumption of supplies corresponding to the number of evacuees from the number of supplies registered in the management device 100. The prediction unit 12 outputs the supply indicator (shortage, sufficient, surplus) according to the current surplus or shortage of supplies.

[0030] The prediction unit 12 may predict an indicator of the supply (shortage, sufficient, or surplus) according to the number of days it will take for the supply to be consumed at the present time. For example, the prediction unit 12 calculates how many days' worth of consumption the current supply represents by dividing the current supply by the daily consumption rate of the supply. For example, two thresholds (third threshold and fourth threshold) are set for the number of days it will take for the supply to be consumed (also called the consumption days). The third threshold is a threshold (date and time) for determining whether the supply is short or sufficient according to the consumption days. The fourth threshold is a threshold (date and time) for determining whether the supply is sufficient or surplus according to the consumption days. If the consumption days of the supply are below the third threshold, the supply is short. If the consumption days of the supply are above the third threshold and below the fourth threshold, the supply is sufficient. If the consumption days of the supply exceed the fourth threshold, the supply is in surplus. However, the thresholds set for the consumption days of the supply are not limited to two. The threshold set for the number of days required for the consumption of goods should be determined according to the number of indicators set for the number of days.

[0031] Information on the surplus or shortage of supplies is not limited to indicators set for the number of supplies or the number of days the supplies will last (shortage, sufficient, surplus). The indicators used by the prediction unit 12 for the surplus or shortage of supplies can be set appropriately according to the type and scale of the disaster that occurs. For example, the prediction unit 12 may predict the number of supplies or the number of days the supplies will last as information on the surplus or shortage of supplies.

[0032] The output unit 13 outputs information on the surplus or shortage of supplies predicted by the prediction unit 12. The information on the surplus or shortage of supplies includes information on the surplus or shortage of supplies (insufficient, sufficient, or surplus) for each evacuation center under management.

[0033] Figure 3 shows an example of supply shortage / surplus information 131 being output to a terminal device 170 owned by a supporter. For example, the shortage / surplus information 131 is sent to the supporter's terminal device 170 via email or the like. The shortage / surplus information 131 includes shortage / surplus information for supplies 1 to N for multiple shelters (shelter A, shelter B, ..., shelter Z) (N is a natural number). The shortage / surplus information 131 includes symbols indicating shortage (×), sufficient (○), and surplus (◎). For example, supplies that are particularly in short supply may be highlighted. For example, supplies that are particularly in short supply may be highlighted by displaying them in an easily distinguishable color, in bold, by flashing, or by changing the background color of the text to a more noticeable color. For example, supplies that are in short supply may be displayed in a ranking format according to the degree of shortage or necessity. If there are shelters that are short of the supplies (×) that the aiders intend to send, they can select those shelters as the recipients of the supplies. Also, if a shelter that the aiders intended to send supplies to is in excess of those supplies (◎), they can select a shelter that is short of those supplies as the recipients of the supplies. For example, it is possible that the supplies that the aiders intend to send are in excess at all shelters. In such cases, the aiders can cancel the delivery of the supplies.

[0034] Figure 4 shows an example of displaying a user interface 151 on a supporter's terminal device 170 for requesting the delivery of supplies. The user interface 151 displays information (also called shortage information) indicating which supplies are in short supply at each evacuation center. The user interface 151 also displays cells for entering the quantity of supplies to be sent. In addition, the user interface 151 displays checkboxes for selecting the evacuation center to which the supplies should be sent. In the example in Figure 4, the supporter wishes to send 50 units of supply N to evacuation center B. For example, the delivery request for supplies entered in the user interface 151 is sent to the designated carrier when the OK button is pressed.

[0035] Figure 5 shows an example of a transportation company delivering supplies to designated shelters in response to a delivery request from a supporter. For example, a transportation company that receives a delivery request will deliver the specified quantity of supplies to the designated shelter. For example, a transportation company can plan deliveries based on information about surpluses and shortages, allowing them to deliver supplies in time for shortages. Furthermore, a transportation company may prioritize the delivery of supplies that are not currently in short supply at one shelter to other shelters. For example, designating a transportation company to deliver supplies to multiple shelters could potentially alleviate the situation of multiple transportation companies converging on shelters. For example, it is also possible to have transportation companies deliver supplies to each shelter, taking into account traffic congestion along the delivery routes.

[0036] The output unit 13 may present information on the surplus or shortage of supplies through a website accessible by terminal devices owned by supporters, etc. For example, the output unit 13 may record the information on the surplus or shortage of supplies in a database built on a server or in the cloud. The information on the surplus or shortage of supplies recorded in the database can be accessed by users who have been registered in advance.

[0037] Figure 6 shows an example of how information on future surpluses and shortages of supplies (surplus / shortage information 132, surplus / shortage information 133) is output from a terminal device 170 owned by a supporter. For example, surplus / shortage information 132 and surplus / shortage information 133 are sent to the supporter's terminal device 170 via email or the like. Surplus / shortage information 132 includes information on supplies that are expected to be in short supply at any of the shelters in a few days. In the example in Figure 6, the information "Supply 2 is expected to be in short supply at Shelter A in one week" is displayed. Also in the example in Figure 6, the information "Supply 1 is expected to be in short supply at Shelter B in three days" is displayed. Surplus / shortage information 133 includes surplus / shortage information for supplies 1 to N for multiple shelters (Shelter A, Shelter B, ..., Shelter Z) (N is a natural number). Surplus / shortage information 133 includes symbols indicating the current supply levels: insufficient (×), sufficient (○), or surplus (◎). Furthermore, the surplus / shortage information 133 includes a symbol indicating a potential shortage of supplies in the future (△). If there is a shelter where the supplies to be sent are in short supply (×), the supporter can select that shelter as the target shelter for supply delivery. Also, if a shelter that the supporter was planning to send supplies to has an excess of those supplies (◎), the supporter can select a shelter where those supplies are in short supply (×) as the target shelter for supply delivery. Additionally, the supporter can select a shelter as the target shelter for supply delivery if there are supplies that are not currently in short supply (×) but are expected to be in short supply in the future (△). For example, it is possible that the supplies targeted by the supporter are in excess at all shelters. In such cases, the supporter can cancel the delivery of the supplies.

[0038] Figure 7 shows an example where supplementary information 134 is displayed on a terminal device 170 owned by a supporter, etc., along with information on the surplus or shortage of supplies 135. The supplementary information 134 in Figure 7 includes information about foreigners who have evacuated to the shelters. The supplementary information 134 is not particularly limited as long as it is information about the shelters. For example, the surplus or shortage information 135 and the supplementary information 134 are sent to the supporter's terminal device 170 by email or the like. The surplus or shortage information 135 includes information on the surplus or shortage of supplies 1 to N for multiple shelters (shelter A, shelter B, ..., shelter Z) (N is a natural number). The surplus or shortage information 135 includes symbols indicating shortage (×), sufficient (○), or surplus (◎) of supplies at the present time. The surplus or shortage information 135 may also include symbols indicating the expectation of a future shortage of supplies (△).

[0039] The supplementary information 134 in Figure 7 includes information about foreign evacuees. In the example in Figure 7, the information "There are evacuees from XX country. There is a shortage of △△, which is specific to XX country." is displayed on the aid worker's terminal device 170. The aid worker recognizes from the supplementary information 134 that they can deliver some supplies to the evacuation center where the evacuees from their own country are located. For example, there is a possibility that a shelter may be lacking supplies specific to a country that evacuees from a particular country are seeking. Such specific supplies are likely to be difficult to procure in a typical shelter. Such supplies may be possessed by aid workers from the same country as the evacuee. If aid workers from the same country arrange to send supplies specific to their home country to the shelter that is lacking those supplies, in response to the supplementary information 134, it may be possible to alleviate the shortage. For example, if the municipality has a large population of people from a particular country, spreading information about the shortage of those supplies in that country may lead to aid workers living in that country procuring those supplies. Furthermore, supplementary information 134 may include information on the surplus or shortage of special supplies (food) that do not contain ingredients prohibited by certain religions. Doing so may make it easier to obtain special supplies that are difficult to acquire through general distribution channels.

[0040] The supplementary information 134 in Figure 7 may include information specific to local areas or districts within Japan, not just foreign countries. For example, when a disaster occurs in the Kanto region, the information display device 10 may display information on surpluses and shortages of supplies specific to the Tohoku region. In this case, it may be possible for aid workers living in the Tohoku region to arrange for such supplies. For example, the information display device 10 may notify information about evacuees who have been displaced by a disaster that has occurred in Japan in different formats for domestic and overseas locations. In this case, it may be possible to receive material support not only from within Japan but also from overseas. For example, the information display device 10 may be configured to notify information on surpluses and shortages of supplies at evacuation centers where evacuees who have been displaced by a disaster that has occurred overseas are taking refuge, within Japan. In this case, it may be possible for aid workers in Japan to provide material support to evacuation centers overseas.

[0041] Even in domestic evacuation shelters, there may be evacuees from overseas. In such cases, communication between the shelter operators and the evacuees from overseas may be necessary. Therefore, supplementary information 134 in Figure 7 may include the evacuees' nationality and native language. Doing so could facilitate the arrangement of communication tools such as translators and translation devices that are appropriate for the evacuees' nationality and native language.

[0042] Figure 8 shows an example of displaying surplus / deficit information 131 on a television (also called TV) accessible to supporters. In the example in Figure 8, the output unit 13 outputs the surplus / deficit information of supplies to a server accessible by the terminal equipment of a broadcasting station that broadcasts television or radio. For example, a broadcasting station reports the surplus / deficit information of supplies for each evacuation center through media such as television and radio. Supporters who have checked the surplus / deficit information of supplies for each evacuation center through media such as television and radio can send the necessary supplies to the evacuation center. The example in Figure 8 is not limited to television and radio broadcasting stations, but may also be applied to information sites that provide information on the internet, or to information dissemination media operated by local governments or private companies. Furthermore, the surplus / deficit information 131 may be disseminated not only through video and audio media, but also through paper media such as newspapers. There are no particular limitations on the media used to present the surplus / deficit information 131.

[0043] Figure 9 shows an example of outputting information on the surplus or shortage of supplies to a terminal device 180 of a transportation company that delivers supplies. The transportation company can deliver the necessary supplies to each evacuation center according to the information on the surplus or shortage of supplies for each center. For example, transportation companies could be assigned to each evacuation center in response to the occurrence of a disaster. In this way, transportation companies can deliver supplies to evacuation centers efficiently, which may reduce road congestion that could occur if aid workers deliver supplies by car or other means. For example, if it is reported to the general public that a supply delivery company has been assigned to each evacuation center, it may be possible to reduce the unnecessary delivery of supplies by aid workers who are members of the general public.

[0044] (operation) Next, an example of the operation of the information display device 10 will be explained with reference to the drawings. Figure 10 is a flowchart illustrating an example of the operation of the information display device 10. In the explanation following the flowchart in Figure 10, the information display device 10 will be described as the main operating component.

[0045] In Figure 10, first, the information display device 10 acquires evacuation information and supplies information for each evacuation center (step S11).

[0046] Next, the information display device 10 predicts the surplus or shortage of supplies for each evacuation center based on the acquired evacuation information and supply information (step S12).

[0047] Next, the information display device 10 outputs information on the predicted surplus or shortage of supplies (step S13).

[0048] As described above, the information display device of this embodiment comprises an information acquisition unit, a prediction unit, and an output unit. The information acquisition unit acquires evacuation information, including the number of evacuees at each evacuation center, and material information, including the number of supplies at each evacuation center. The prediction unit predicts surplus and shortage information regarding the surplus or shortage of supplies at each evacuation center based on the evacuation information and material information. The output unit outputs the predicted surplus and shortage information.

[0049] According to the information display device of this embodiment, by outputting information on surpluses and shortages of supplies predicted in response to evacuation information and supply information, it is possible to appropriately present to the supporters the evacuation centers to which they should provide the supplies they wish to deliver.

[0050] Staff working on-site at evacuation centers are often busy dealing with complaints from evacuees and are unable to fully grasp the situation on the ground. As a result, it is difficult for the management to thoroughly manage the inventory and consumption of supplies. With the method of this embodiment, if the inventory of supplies and the number of evacuees can be grasped, the supporters can proceed with arranging for supplies, thus accurately supplying the supplies that are in short supply at the evacuation center.

[0051] In one embodiment of this system, the prediction unit predicts surplus and shortage information for each evacuation center, determining the surplus or shortage of supplies using the indicators of shortage, sufficient, and surplus. According to this embodiment, the surplus or shortage of supplies can be confirmed according to the indicators of shortage, sufficient, and surplus.

[0052] In one embodiment of this system, the prediction unit predicts a shortage or surplus of goods based on a first threshold for determining whether the quantity of goods is insufficient or sufficient, and a second threshold for determining whether the quantity of goods is sufficient or in excess. If the quantity of goods falls below the first threshold, the prediction unit predicts that there is a shortage of goods. If the quantity of goods is equal to or greater than the first threshold and less than or equal to the second threshold, the prediction unit predicts that there is a surplus of goods. If the quantity of goods exceeds the second threshold, the prediction unit predicts that there is a surplus of goods. According to this system, the predicted shortage or surplus information can be confirmed according to the quantity of goods.

[0053] In one embodiment of this system, the prediction unit predicts the surplus or shortage of supplies at each evacuation center based on the amount of consumption corresponding to the number of evacuees at each center. According to this embodiment, information on the surplus or shortage of supplies according to the amount of consumption at each evacuation center can be confirmed.

[0054] In one embodiment of this system, the prediction unit predicts the number of days each item will be consumed, using the current number of items in each shelter and the daily consumption rate of items in each shelter. The prediction unit predicts the shortage or surplus of items based on a third threshold for determining whether the items are insufficient or sufficient according to the number of days of consumption, and a fourth threshold for determining whether the items are insufficient or surplus according to the number of days of consumption. If the number of days of consumption falls below the third threshold, the prediction unit predicts that there will be a shortage of items. If the number of days of consumption is equal to or greater than the third threshold and less than or equal to the fourth threshold, the prediction unit predicts that there will be a surplus of items. If the number of days of consumption exceeds the fourth threshold, the prediction unit predicts that there will be a surplus of items. According to this embodiment, the predicted surplus or shortage information according to the number of days of consumption of items can be confirmed.

[0055] In one embodiment of this system, the output unit outputs information about surpluses and shortages to terminal devices owned by at least one of the following: supporters assisting in the provision of supplies, transporters delivering supplies, and broadcasting stations reporting information about evacuation centers. According to this embodiment, the supporters, transporters, and broadcasting stations can provide the evacuation centers with the supplies they are lacking based on the information about surpluses and shortages they have acquired.

[0056] (Second embodiment) Next, an information display device according to the second embodiment will be described with reference to the drawings. The information display device of this embodiment displays information about evacuation centers (also called evacuation center information) in accordance with information on the surplus or shortage of supplies at each evacuation center, in response to evacuation reservations made by persons subject to evacuation.

[0057] Figure 11 is a block diagram showing an example of the configuration of the information display device 20 according to this embodiment. The information display device 20 includes an information acquisition unit 21, a prediction unit 22, a first output unit 24, an evacuation reservation acquisition unit 25, an evacuation shelter allocation unit 26, and a second output unit 27. The first output unit 24 and the second output unit 27 constitute an output unit 23.

[0058] The information acquisition unit 21 has the same configuration as the information acquisition unit 11 in the first embodiment. The information acquisition unit 21 acquires evacuation information for each evacuation center. The information acquisition unit 21 also acquires supplies information for each evacuation center. The evacuation information and supplies information acquired by the information acquisition unit 21 are the same as in the first embodiment.

[0059] The prediction unit 22 has the same configuration as the prediction unit 12 in the first embodiment. The prediction unit 22 acquires evacuation information and supply information for each evacuation center from the information acquisition unit 21. The prediction unit 22 predicts the surplus or shortage of supplies for each evacuation center according to the acquired evacuation information and supply information. The prediction unit 22 predicts the surplus or shortage information (shortage, sufficient, or surplus) for each evacuation center under management. The prediction unit 22 outputs information regarding the surplus or shortage of supplies for each evacuation center (also called surplus or shortage information) to the first output unit 24 and the evacuation center allocation unit 26.

[0060] The first output unit 24 has the same configuration as the output unit 13 of the first embodiment. The first output unit 24 outputs information on the surplus or shortage of supplies predicted by the prediction unit 22. The information on the surplus or shortage of supplies includes information on the surplus or shortage of supplies (insufficient, sufficient, or surplus) for each evacuation center under management. The first output unit 24 may also present the information on the surplus or shortage of supplies through a website that can be accessed by terminal devices owned by supporters, etc. For example, the first output unit 24 may record the information on the surplus or shortage of supplies in a database built on a server or in the cloud. The information on the surplus or shortage of supplies recorded in the database can be accessed by pre-registered users. For example, the first output unit 24 may notify the person who made the evacuation reservation of the information on the surplus or shortage of supplies.

[0061] The evacuation reservation acquisition unit 25 acquires evacuation reservations from persons subject to evacuation. For example, the evacuation reservation acquisition unit 25 acquires evacuation reservations entered via a terminal device (not shown) owned by the person subject to evacuation. For example, the user interface for entering evacuation reservations is built to be accessible via a website.

[0062] The shelter allocation unit 26 obtains evacuation reservations from the evacuation reservation acquisition unit 25. The shelter allocation unit 26 also obtains information on the surplus or shortage of supplies for each shelter from the prediction unit 22. In response to the evacuation reservations, the shelter allocation unit 26 searches for shelters that have sufficient supplies for the evacuees who made the evacuation reservations. The shelter allocation unit 26 assigns the searched shelters to the evacuees who made the evacuation reservations. The shelter allocation unit 26 outputs information about the shelters assigned to the evacuees (also called shelter information) to the second output unit 27. Details of the shelter allocation by the shelter allocation unit 26 will be described later.

[0063] The second output unit 27 outputs shelter information related to the shelters assigned by the shelter assignment unit 26. The evacuation information output from the second output unit 27 is notified to the person who requested the evacuation reservation. For example, the shelter information includes the name, location, and capacity of the shelter. The shelter information may also include information on supplies and information on shortages or surpluses of supplies. For example, if there are shortages of supplies at the assigned shelter, the person who is evacuated can bring those supplies with them when they evacuate. For example, the person who is evacuated can bring extra supplies that are in short supply at the assigned shelter and distribute them to other evacuees.

[0064] Figure 12 is a conceptual diagram summarizing the relationship between the information acquired and provided by the information display device 20. For example, evacuation reservations of evacuees are acquired from the mobile terminal 260 owned by the evacuee. For example, evacuation information and supply information for each evacuation center are acquired from a management device (not shown) that manages the evacuation centers under management. The information display device 20 notifies the evacuee who requested the evacuation reservation of evacuation center information, including information about the assigned evacuation center. The information display device 20 also notifies the terminal device 270 of the surplus or shortage information 230 for each evacuation center. The surplus or shortage information 230 for each evacuation center may also be output to the mobile terminal 260 owned by the evacuee. For example, a supply search function corresponding to the surplus or shortage information 230 for each evacuation center may be installed on the mobile terminal 260 owned by the evacuee. For example, the supply search function may be configured to search for evacuation centers where there are sufficient supplies necessary for the evacuee and where the evacuee can evacuate. In this way, those who are evacuated can use a supplies search function to find shelters that have sufficient supplies for them and that they can take refuge in. For example, information on surpluses and shortages of supplies 230 could be provided through a website. In this way, those who are evacuated can use the website's search function to find shelters that have sufficient supplies for them and that they can take refuge in.

[0065] The mobile terminal 260 is a communication device that can be carried by the person to be evacuated (user). For example, the mobile terminal 260 is a communication device with communication functions such as a smartphone, smartwatch, or mobile phone. The mobile terminal 260 transmits the evacuation reservation entered by the person to be evacuated to the information display device 20.

[0066] For example, the mobile terminal 260 may have a function to determine its position using GNSS (Global Navigation Satellite System). For example, the mobile terminal 260 may be equipped with a positioning function using GPS (Global Positioning System). The mobile terminal 260 generates location information for the mobile terminal 260 using positioning signals transmitted from artificial satellites such as GPS satellites and quasi-zenith satellites. The mobile terminal 260 transmits the generated location information, along with the evacuation reservation, to the information display device 20. The location information of the mobile terminal 260 may be used to select candidate evacuation shelters. For example, the evacuation shelter allocation unit 26 narrows down the candidate evacuation shelters according to the location information of the person who made the evacuation reservation. For example, the evacuation shelter allocation unit 26 selects evacuation shelters within a predetermined range as candidate evacuation shelters based on the location information of the person who made the evacuation reservation.

[0067] Furthermore, the mobile terminal 260 receives evacuation information transmitted from the information display device 20. The mobile terminal 260 displays information about evacuation shelters included in the received evacuation information on its screen. Here, it is assumed that an application for processing evacuation information transmitted from the information display device 20 is installed on the mobile terminal 260. For example, an application for providing supplies to general supporters may be created. By displaying evacuation shelters that need supplies through such an application, appropriate information can be shared and confirmed by many people on a single platform. Such an application may also have a supply search function that corresponds to the supply shortage / surplus information 230 for each evacuation shelter. For example, the supply shortage / surplus information 230 may be displayed through a website. In that case, general supporters can search for the supply shortage / surplus information 230 using the website's search function.

[0068] Figure 13 shows an example of a management table (evacuation reservation management table 235) used to manage evacuation reservations from those subject to evacuation. The evacuation reservation management table 235 includes the number of evacuees and the number of evacuation reservations for each evacuation center. The evacuation reservation management table 235 also includes information on the surplus or shortage of supplies for each evacuation center. The information on the surplus or shortage of supplies includes the current surplus or shortage information (upper row). The information on the surplus or shortage of supplies also includes the surplus or shortage information when the number of evacuees from the number of reservations is added to the current number of evacuees (in parentheses in the lower row). For example, if there is a surplus of supplies (◎) in the current situation, it is predicted that when the number of evacuees from the number of reservations is added to the current number of evacuees, the supplies will be sufficient (○). For example, if there are sufficient supplies (○) in the current situation, it is predicted that when the number of evacuees from the number of reservations is added to the current number of evacuees, the supplies will be insufficient (△). The shelter allocation unit 26 assigns shelters to those who have made evacuation reservations, ensuring that there is no shortage of necessary supplies for them, even if additional evacuees are added to the original request.

[0069] Figure 14 is a conceptual diagram showing an example of how evacuation information transmitted from the information display device 20 is displayed on the mobile terminal 260 of the person to be evacuated (user). In the example in Figure 14, it is assumed that the information display device 20 generates evacuation information corresponding to the location information of the mobile terminal 260, in response to an evacuation reservation that includes the location information of the mobile terminal 260 carried by the person to be evacuated. It is also assumed that the person to be evacuated (user) needs supplies 1. For example, the supplies needed by the person to be evacuated (user) are estimated according to the attributes of the person to be evacuated, such as gender and age. For example, if the person to be evacuated is male, it is desirable that there be enough supplies such as razors. For example, if the person to be evacuated is female, it is desirable that there be enough supplies such as cosmetics. For example, if the person to be evacuated is a child, it is desirable that there be enough supplies such as sweets and games. For example, if the person to be evacuated is elderly, it is desirable that there be enough supplies such as tea and snacks. For example, the supplies needed by the person to be evacuated may be pre-entered for each person to be evacuated. By pre-registering the necessary supplies for each person to be evacuated, it becomes possible to select an evacuation center that has sufficient supplies tailored to the preferences of those people.

[0070] In the example shown in Figure 14, the screen of the user's mobile device 260 displays evacuation shelter information, including information about the evacuation shelter assigned to that user. In the example in Figure 14, the information "Evacuation Shelter A has sufficient supplies 1. Please evacuate to Evacuation Shelter A." is displayed on the screen of the mobile device 260. In addition, the screen of the mobile device 260 displays an evacuation map, including the route from the mobile device 260's location at the time of sending the evacuation reservation to the evacuation shelter. After the user confirms the evacuation information displayed on the screen of the mobile device 260, they can evacuate to the evacuation shelter according to that information. By evacuating while checking the evacuation map, the user can ensure they reach the evacuation shelter safely.

[0071] Figure 15 shows another example of a management table (evacuation reservation management table 236) used to manage evacuation reservations from those who are to be evacuated. Evacuation reservation management table 236 includes the number of evacuees and the number of evacuation reservations for each evacuation center. Evacuation reservation management table 235 also includes information on the surplus or shortage of supplies for each evacuation center. The information on the surplus or shortage of supplies includes current surplus or shortage information (upper row). The information on the surplus or shortage of supplies also includes surplus or shortage information when the number of evacuees in the number of evacuation reservations is added to the current number of evacuees (lower row in parentheses). Furthermore, the information on the surplus or shortage of supplies includes surplus or shortage information based on the projected amount of supplies in the future. For example, supply 2 at evacuation center A is currently insufficient (×). However, in two days, supply 2 at evacuation center A is expected to become surplus (◎). If the person who requested the evacuation reservation needs supply 2, at this time, evacuation center A cannot be assigned to that person. However, in two days, evacuation center A can be assigned to that person. If the evacuation of those subject to evacuation is not urgent, the evacuation shelter allocation unit 26 may allocate evacuation shelters to those subject to evacuation who have requested evacuation reservations, in accordance with future information on surpluses and shortages of supplies. For example, the evacuation shelter allocation unit 26 may be configured not to allocate evacuation shelters that are currently sufficient in some supplies but will be in short supply of those supplies in the future to those subject to evacuation who need those supplies.

[0072] Figure 16 is a conceptual diagram showing another example of how evacuation information transmitted from the information display device 20 is displayed on the mobile terminal 260 of the person to be evacuated (user). In the example in Figure 16, it is assumed that the information display device 20 generates evacuation information corresponding to the location information of the mobile terminal 260, in response to an evacuation reservation that includes the location information of the mobile terminal 260 carried by the person to be evacuated. It is also assumed that the person to be evacuated (user) needs supplies 2.

[0073] In the example shown in Figure 16, the screen of the user's mobile device 260 displays evacuation shelter information, including information about the evacuation shelter assigned to that user. In the example in Figure 16, the information displayed on the screen of the mobile device 260 is: "In two days, there will be enough supplies 2 at evacuation shelter A. Please evacuate to evacuation shelter A in two days." In addition, the screen of the mobile device 260 displays an evacuation map, including the route from the mobile device 260's location at the time of sending the evacuation reservation to the evacuation shelter. After the user confirms the evacuation information displayed on the screen of the mobile device 260, they can evacuate to the evacuation shelter two days later according to that information. By evacuating while checking the evacuation map, the user can ensure they reach the evacuation shelter safely.

[0074] (operation) Next, an example of the operation of the information display device 20 will be explained with reference to the drawings. Figure 17 is a flowchart for explaining an example of the operation of the information display device 10. In the explanation following the flowchart in Figure 17, the information display device 20 will be described as the main operator. In the flowchart in Figure 17, the output of information on the surplus or shortage of materials will be omitted.

[0075] In Figure 17, first, the information display device 20 obtains evacuation reservations from the persons to be evacuated (step S21).

[0076] Next, the information display device 20 acquires evacuation information and supply information for each evacuation center (step S22).

[0077] Next, the information display device 20 predicts the surplus or shortage of supplies for each evacuation center based on the acquired evacuation information and supply information (step S23).

[0078] Next, the information display device 20 assigns evacuation centers to those who are to be evacuated, according to the predicted information on the surplus or shortage of supplies at each center (step S24).

[0079] Next, the information display device 20 notifies the person to be evacuated of the evacuation shelter information assigned to that person (step S25).

[0080] As described above, the information presentation device of this embodiment comprises an information acquisition unit, a prediction unit, an evacuation reservation acquisition unit, an evacuation shelter allocation unit, and an output unit. The information acquisition unit acquires evacuation information, including the number of evacuees at each evacuation shelter, and material information, including the number of supplies at each evacuation shelter. The prediction unit predicts surplus and shortage information regarding the surplus or shortage of supplies at each evacuation shelter based on the evacuation information and material information. The evacuation reservation acquisition unit acquires evacuation reservations from those who are to be evacuated. The evacuation shelter allocation unit assigns one of the evacuation shelters to the person who requested the evacuation reservation, using the surplus and shortage information predicted by the prediction unit, based on the evacuation reservation. The output unit outputs the predicted surplus and shortage information. The output unit also notifies the person who is to be evacuated of evacuation shelter information, including information about the evacuation shelter assigned to them.

[0081] According to the information display device of this embodiment, by outputting information on surpluses and shortages of supplies predicted based on evacuation information and supply information, it is possible to appropriately present to supporters the evacuation shelters to which they should provide the supplies they wish to deliver. Furthermore, according to the information display device of this embodiment, it is possible to assign evacuation shelters to those who are to be evacuated based on the information on surpluses and shortages of supplies.

[0082] In one embodiment of this system, the evacuation reservation acquisition unit acquires an evacuation reservation, including the location information of the mobile device, from the mobile device owned by the person to be evacuated. The evacuation shelter allocation unit selects candidate evacuation shelters to be assigned to the person to be evacuated based on the location information of the mobile device. From the selected candidate evacuation shelters, the evacuation shelter allocation unit assigns the person to an evacuation shelter that has sufficient supplies necessary for them. According to this embodiment, the person to be evacuated is assigned an evacuation shelter that has sufficient supplies necessary for them, based on their location.

[0083] (Third embodiment) Next, an information display device according to the third embodiment will be described with reference to the drawings. The information display device of this embodiment has a simplified configuration compared to the information display devices of the first and second embodiments.

[0085] The information acquisition unit 31 acquires evacuation information, including the number of evacuees at each evacuation center, and supply information, including the number of supplies at each evacuation center. The prediction unit 32 predicts surplus and shortage information regarding the surplus or shortage of supplies at each evacuation center based on the evacuation information and supply information. The output unit 33 outputs the predicted surplus and shortage information.

[0086] As described above, the information display device of this embodiment can appropriately present to supporters the evacuation shelters to which they should provide the supplies they wish to deliver by outputting information on the predicted surplus or shortage of supplies based on evacuation information and supply information.

In the process of predicting the surplus and shortage information, the surplus or shortage of supplies for each evacuation center is determined using the indicators of shortage, sufficient, and surplus. In the process of predicting the surplus or shortage information, a first threshold for determining whether the quantity of goods is insufficient or sufficient, and a second threshold for determining whether the quantity of goods is sufficient or in excess, are used as criteria. If the number of supplies falls below the first threshold, it is predicted that there is a shortage of supplies. If the number of supplies is equal to or greater than the first threshold and less than or equal to the second threshold, it is predicted that the supplies are sufficient. A program that predicts a surplus of goods if the number of goods exceeds the second threshold.

10. A process for acquiring evacuation information including the number of evacuees at each evacuation center, and material information including the number of supplies at each evacuation center, A process to predict surplus or shortage information regarding the surplus or shortage of supplies for each evacuation center, based on the evacuation information and the supply information, The computer is made to perform a process that outputs the predicted surplus or deficit information. In the process of predicting the surplus and shortage information, the surplus or shortage of supplies for each evacuation center is determined using the indicators of shortage, sufficient, and surplus. In the process of predicting the surplus and shortage information, the current number of supplies for each shelter and the daily consumption rate of supplies at each shelter are used to predict the number of days each supply will be consumed. Based on a third threshold for determining whether there is a shortage or sufficiency of goods according to the number of days of consumption, and a fourth threshold for determining whether there is an excess or sufficiency of goods according to the number of days of consumption, If the number of days of consumption falls below the third threshold, a shortage of supplies is predicted. If the number of days of consumption is equal to or greater than the third threshold and less than or equal to the fourth threshold, it is predicted that there are enough supplies. A program that predicts a surplus of goods if the number of days of consumption exceeds the fourth threshold.
