Description

[Technical Field]

[0001] The present invention relates to a decision support device, a decision support method using the same, and a program for realizing these. [Background technology]

[0002] When a disaster occurs, disaster situation assessment and decision-making are based on a large amount of spatially and temporally related information, such as meteorological information, geographical information, information on people flow, and hazard information. However, it is not easy to extract meaningful information for assessing the disaster situation and making decisions from the wide variety of disaster-related information that changes from moment to moment. How to manage and disseminate disaster-related information is important for rapid and appropriate disaster response.

[0003] For example, with regard to the transmission of information when a disaster occurs, Patent Document 1 discloses a technology for transmitting disaster-related information with priority over other information. Patent Document 2 discloses a technology for determining which disaster-related information is to be transmitted with priority. Furthermore, with regard to the management of a wide variety of disaster-related information, Patent Document 3 discloses a technology for efficiently managing information by adding location and time information as text information to disaster information collected as image information. Furthermore, as a technology for supporting disaster response, Patent Document 4 discloses a technology for managing the recognition of a disaster situation and the implementation of countermeasures on a time axis while sequentially presenting predetermined countermeasures for disaster-related information at each point in time.

[0005] As time passes after a disaster occurs, the disaster response that should be carried out changes. For example, immediately after a disaster occurs, it is important to understand the damage situation, and in the initial phase of disaster response, the priority is given to rescuing the victims. Therefore, the disaster-related information required for disaster response changes depending on the phase of the disaster response.

[0006] However, particularly in areas that have not experienced disasters in the past, it may be difficult to know which disaster-related information to check in each phase. If important disaster-related information could be presented to users according to each phase, users would be able to grasp the disaster situation and make decisions more quickly and appropriately. However, the above-mentioned Patent Documents 1 to 4 do not take into account the phases of disaster response when transmitting disaster-related information.

[0007] An example of an object of the present invention is to provide a decision support device, a decision support method, and a program that can present important disaster-related information according to the phase of disaster response and support a user's decision-making.

[0013] [1. Overview] First, the configuration and functions of a decision support device 100 according to one embodiment of the present invention will be described with reference to Fig. 1. Fig. 1 is a block diagram showing an example of the configuration of the decision support device 100 according to this embodiment.

[0014] The decision support device 100 according to this embodiment is a device that supports a user in making a decision on a disaster situation. When a disaster occurs, a user grasps the disaster situation and makes decisions based on a large amount of spatially and temporally related disaster-related information, such as meteorological information, geographical information, people flow information, and hazard information. In situations where a quick and accurate response is required, it is difficult to correctly judge the situation while referring to the large amount of disaster-related information that changes from moment to moment.

[0015] Furthermore, disaster response measures change as time passes after a disaster occurs. Therefore, the disaster-related information required for disaster response changes depending on the phase of the disaster response. However, decisions and responses when a disaster occurs are often based on know-how determined based on past cases. For this reason, especially in areas that have not experienced disasters in the past, it can be difficult to know which disaster-related information to check at each phase of disaster response.

[0016] Therefore, the decision support device 100 according to this embodiment presents important disaster-related information according to the phase of disaster response, thereby supporting even decision-makers who have no knowledge or experience of disaster response to make appropriate judgments about the situation during a disaster.

[0017] 1, the decision support device 100 includes an elapsed time information output unit 110 and a determination unit 120. The elapsed time information output unit 110 outputs elapsed time information indicating the elapsed time from a reference time. The determination unit 120 determines disaster-related information to be presented to the user based on the elapsed time information.

[0018] The decision support device 100 calculates elapsed time information at the time when the presentation information is presented to the user, and based on the calculated elapsed time information, presents the user with useful disaster-related information that is important when deciding on a disaster response at that phase. The user can check important information for each phase of the disaster response, allowing them to grasp the disaster situation and make decisions more quickly and appropriately.

[0019] [2. Equipment configuration] The configuration and functions of the decision support device 100 according to this embodiment will be described with reference to Figs. 2 to 5. Fig. 2 is an explanatory diagram showing an overview of the processing performed by the decision support device 100 according to this embodiment. Fig. 3 is a block diagram showing an example of the configuration of the decision support device 100 according to this embodiment. Fig. 4 is an explanatory diagram showing an example of the correspondence between the elapsed time from the starting point and the phase. Fig. 5 is an explanatory diagram showing an example of the correspondence between the phase and the disaster-related information to be presented.

[0020] As shown in FIG. 2, the determination support device 100 according to this embodiment determines disaster-related information to be presented to a user from a plurality of pieces of disaster-related information based on elapsed time information indicating the time elapsed from a reference time that is a starting point.

[0021] Here, disaster-related information includes, for example, weather information, people flow information, information regarding emergency calls to fire departments, evacuation shelter information, lifeline information, hazard maps, important facility information, disaster-related SNS (social networking service), and the like.

[0022] Weather information includes, for example, rainfall information, raincloud information, snowfall information, wind speed information, and temperature information. People flow information represents the ever-changing flow of people, and is represented, for example, by people's movement paths. Information regarding emergency calls to fire departments includes, for example, the number of emergency calls and the history of fire department dispatches in response to calls. Evacuation shelter information includes, for example, the location of the evacuation shelter, its capacity, and its current capacity. Lifeline information includes information on damage to infrastructure facilities such as electricity, water, gas, and communications. Hazard maps represent risk information on floods, landslides, and tsunamis, and road disaster prevention information, in association with geographic information. Important facility information includes information on hospitals and other facilities that will become important in the event of a disaster. Disaster-related SNS includes, for example, the number of SNS posts and photos posted when a disaster occurs.

[0023] The disaster-related information may be acquired as time-series data for each area, for example. The time-series data may be continuous or discontinuous in time. In addition to the disaster-related information, the determination support device 100 may also treat topographical information such as elevation as disaster-related information.

[0024] Furthermore, the elapsed time information may be, for example, the elapsed time itself from the starting point, or the disaster response phase corresponding to the elapsed time from the starting point. A disaster response phase is a time stage set according to the required disaster response. For example, phases such as the alert period, immediately after the disaster occurs, the initial period, and the emergency period are set. The elapsed time information may also represent a negative time from the starting point, such as the alert period phase.

[0025] For a user to whom disaster-related information is presented, the disaster-related information that is important changes depending on the elapsed time information. For example, during the alert period, information A, B, C, and D are important disaster-related information, while during the initial response period, information A, X, Y, and Z are important disaster-related information. The decision support device 100 according to this embodiment presents the user with the disaster-related information that is important at that time based on the elapsed time information.

[0026] The configuration of the decision support device 100 according to this embodiment will be described in more detail. As shown in Fig. 3, the decision support device 100 includes an elapsed time information output unit 110, a determination unit 120, a reference time acquisition unit 130, a phase estimation unit 140, a disaster-related information acquisition unit 150, a presentation processing unit 160, and a storage unit 170.

[0027] As described in FIG. 1, the elapsed time information output unit 110 outputs elapsed time information indicating the elapsed time from a reference time as the starting point. The elapsed time information output unit 110 obtains the elapsed time information from a reference time acquired by a reference time acquisition unit 130 (described later) as the starting point. The elapsed time information may be the elapsed time itself from the starting point, or may be a disaster response phase corresponding to the elapsed time from the starting point. The elapsed time information output unit 110 outputs the elapsed time information to the determination unit 120. Note that the elapsed time information output unit 110 may also output a phase estimated by a phase estimation unit 140 (described later).

[0028] As described in FIG. 1 , the determination unit 120 determines disaster-related information to be presented to the user based on the elapsed time information input from the elapsed time information output unit 110. The disaster-related information corresponding to the elapsed time information is set in advance and is recorded, for example, in the storage unit 170 described below. The determination unit 120 determines the disaster-related information to be presented to the user by referring to the storage unit 170. Then, the determination unit 120 outputs information that can identify the determined disaster-related information to the presentation processing unit 160.

[0029] The reference time acquisition unit 130 acquires a reference time that is the starting point of the elapsed time information. For example, in the case of an earthquake, the reference time may be the startup time of the decision support device 100 or the time a disaster prevention headquarters is established. Furthermore, for example, in the case of a windstorm or flood disaster, the reference time may be the predicted time of arrival of a typhoon or the time a warning is issued. Upon acquiring the reference time, the reference time acquisition unit 130 outputs the reference time to the elapsed time information output unit 110.

[0030] The phase estimation unit 140 estimates the phase of disaster response based on at least one disaster-related information item. The phase estimation unit 140 analyzes the disaster-related information item to estimate the current phase.

[0031] Specifically, the phase estimation unit 140 may estimate the current phase based on a preset rule-based estimation process. For example, consider a case where the current phase is estimated based on information regarding emergency calls to a fire department. In this case, if the number of emergency calls and the number of fire department dispatches in response to the calls increase and the number of cases remains high, the current phase may be estimated as the initial response period. Alternatively, if the number of emergency calls and the number of fire department dispatches in response to the calls decrease and fall below a predetermined number, or if regular requests for supply distribution continue, the current phase may be estimated as the recovery period. The phase estimation unit 140 may estimate the current phase using such rule-based estimation. Instead of using a rule-based estimation method, the phase estimation unit 140 may estimate the current phase using an estimation model modeled by machine learning.

[0032] The phase estimation unit 140 outputs the estimated phase to the elapsed time information output unit 110. Note that the phase estimation unit 140 does not necessarily have to be provided in the decision support device 100 according to this embodiment. For example, the phase estimation unit 140 only needs to function when the reference time acquisition unit 130 cannot acquire the reference time and the elapsed time information output unit 110 cannot obtain the elapsed time information.

[0033] The disaster-related information acquisition unit 150 acquires disaster-related information from a server or the like connected to the decision support device 100 via a network. The disaster-related information acquisition unit 150, for example, collects information sent by national and local government administrative agencies and companies that provide infrastructure facilities, and collects social media posts sent by residents. The disaster-related information acquisition unit 150 periodically acquires disaster-related information and outputs it to the presentation processing unit 160. The timing of acquiring the disaster-related information can be set appropriately by the user. The disaster-related information acquisition unit 150 may output the acquired disaster-related information to the phase estimation unit 140.

[0034] The presentation processing unit 160 performs processing to present the disaster-related information determined by the determination unit 120 to the output device 300. When the presentation processing unit 160 acquires the disaster-related information determined by the determination unit 120 from the disaster-related information acquisition unit 150, the presentation processing unit 160 outputs the information to the output device 300. At this time, the presentation processing unit 160 may perform display processing to adjust, for example, the size and presentation position of the disaster-related information when it is presented on the output device 300. The output device 300 outputs the disaster-related information input from the presentation processing unit 160 and presents it to the user.

[0035] The storage unit 170 stores various information required for the processing performed by the decision support device 100. The storage unit 170 stores information such as the correspondence between the time elapsed from the starting point and the phase, and the correspondence between the phase and the disaster-related information to be presented.

[0036] For example, the correspondence between the time elapsed from the starting point and the phase may be stored as an elapsed time information table 171 as shown in Fig. 4. In the elapsed time information table 171, a corresponding phase 171a and a time elapsed from the starting point 171b are recorded in association with each other. Furthermore, for example, the correspondence between a phase and disaster-related information to be presented may be stored as a presented information table 173 as shown in Fig. 5. In the presented information table 173, a corresponding phase 173a and disaster-related information 173b that is recommended to be presented are recorded in association with each other.

[0037] The storage unit 170 may also store, for example, a rule base or estimation model used when estimating a phase based on disaster-related information, and information such as the size and presentation position of the disaster-related information when presented on the output device 300. This information may be updateable by the user at any timing via the input device 200. The information recorded in the storage unit 170 can be referenced by each functional unit constituting the decision support device 100.

[0038] The decision support device 100 is connected to an input device 200 and an output device 300. The input device 200 is an interface that a user operates to input information, such as a mouse, keyboard, touch panel, button, switch, or lever. The output device 300 is a device for presenting information to a user, and may be a display device such as a liquid crystal display device, a plasma display device, or an EL display device. Alternatively, the output device 300 may be a printer, a mobile communication terminal, a facsimile machine, or the like.

[0039] [3. Decision support method] [3-1. Processing Contents] The decision support method according to this embodiment will be described below with reference to Fig. 6. Fig. 6 is a flowchart showing an example of the decision support method according to this embodiment. The decision support method according to this embodiment is implemented by operating the decision support device 100.

[0040] (S100: Obtain reference time) 6, first, the reference time acquisition unit 130 acquires a reference time that is to be used as a starting point for elapsed time information (S100). The reference time can be acquired from a server or the like connected to the decision support device 100 via a network. The reference time acquisition unit 130 may also set the time that is to be used as the reference time depending on the type of disaster, such as an earthquake, wind or flood damage, etc. Upon acquiring the reference time, the reference time acquisition unit 130 outputs the reference time to the elapsed time information output unit 110.

[0041] (S110: Output elapsed time information) Next, the elapsed time information output unit 110 outputs elapsed time information indicating the elapsed time since the reference time acquired in step S100. The elapsed time information output unit 110 obtains elapsed time information at the current time or a specified time, starting from the reference time acquired in step S100. The elapsed time information may be the elapsed time itself from the starting point. Alternatively, the elapsed time information may be the disaster response phase identified based on the elapsed time information table 171 shown in FIG. 4, for example.

[0042] Furthermore, the elapsed time information output unit 110 may output the phase estimated by the phase estimation unit 140 as the elapsed time information. For example, when the reference time cannot be acquired in step S100 and the elapsed time information output unit 110 cannot determine the elapsed time information, the phase estimated by the phase estimation unit 140 may be used. The elapsed time information output unit 110 outputs the elapsed time information to the determination unit 120.

[0043] (S120: Deciding on disaster-related information to present) Thereafter, the determination unit 120 determines disaster-related information to be presented to the user based on the elapsed time information output by the elapsed time information output unit 110 in step S110 (S120). The determination unit 120 may determine the disaster-related information to be presented to the user, for example, by referring to the presentation information table 173 shown in Fig. 5. The determination unit 120 determines the disaster-related information that is recommended to be presented in the presentation information table 173 and that can be acquired by the disaster-related information acquisition unit 150 as the disaster-related information to be presented to the user.

[0044] The determination unit 120 may present a predetermined number of pieces of disaster-related information to the user. In this case, for example, by setting a presentation priority for each piece of disaster-related information in the presentation information table 173, the determination unit 120 can determine the disaster-related information to be presented to the user in descending order of priority. The determination unit 120 outputs information that can identify the determined disaster-related information to the presentation processing unit 160. Note that the information that can identify the disaster-related information is, for example, the name of the disaster-related information, a weighting coefficient or an index associated with the disaster-related information, or the like. When the determination unit 120 acquires disaster-related information to be presented from the disaster-related information acquisition unit 150, the disaster-related information is output directly from the determination unit 120 to the presentation processing unit 160.

[0045] (S130: Presentation of disaster-related information) When the disaster-related information to be presented to the user is determined in step S120, the presentation processing unit 160 causes the output device 300 to present the designated disaster-related information (S130). The presentation processing unit 160 acquires corresponding disaster-related information from the disaster-related information acquisition unit 150 based on the information capable of identifying the disaster-related information input from the determination unit 120 in step S120. Upon acquiring the disaster-related information, the presentation processing unit 160 outputs the acquired disaster-related information to the output device 300. At this time, the presentation processing unit 160 may perform display processing to adjust, for example, the size, presentation position, etc. of the disaster-related information when presented on the output device 300. The output device 300 outputs the disaster-related information input from the presentation processing unit 160 and presents it to the user.

[0046] The above has described the decision support method according to this embodiment. In the process shown in Fig. 6, the processes of steps S110 to S130 may be repeatedly executed at predetermined time intervals. This allows the user to check disaster-related information according to desired elapsed time information.

[0047] [3-2. Examples of disaster-related information] As a specific method of presenting disaster-related information, for example, disaster-related information for each disaster response phase may be displayed in different windows, and the display may be switched using tabs. Alternatively, an icon for each phase may be displayed on the screen of the output device 300, and a window displaying disaster-related information for the selected phase may be displayed. In this way, when a user selects a disaster response phase, disaster-related information according to elapsed time information may be presented to the user. Alternatively, a tab or icon specifying the present may be set, and important disaster-related information based on the current elapsed time information may be displayed. This allows the user to check currently useful disaster-related information without worrying about the current disaster response phase.

[0048] Alternatively, the disaster-related information presented to the user may be automatically switched as time passes. For example, the decision support device 100 automatically acquires a reference time and calculates elapsed time information based on preset conditions. The calculation of the elapsed time information is repeatedly performed to grasp changes in the phase. Then, the decision support device 100 causes the output device 300 to present corresponding disaster-related information based on the calculated elapsed time information. As a result, when the phase transitions to the next phase as time passes, disaster-related information that is important in the next phase is automatically presented to the output device 300.

[0049] Furthermore, useful disaster-related information may differ depending on the user's attributes, such as the local government, fire department, or general citizen, and the role in disaster response (supervisor, person in charge, etc.). Therefore, by setting in advance the correspondence between the phase of the presentation information table 173 or the like and the disaster-related information to be presented for each user attribute, it becomes possible to present useful disaster-related information according to elapsed time information for each user attribute.

[0050] For example, as shown in FIG. 7, let us take the user attributes of a local government supervisor (user A) and a disaster response officer (user B). The supervisor is presented with disaster-related information necessary for deciding on a government response according to each phase. On the other hand, the officer is presented with disaster-related information necessary for responding to inquiries from the general public according to each phase. For this reason, for example, information E is presented to the officer instead of information B that was presented to the supervisor during the alert phase, and information W is presented to the officer instead of information Z that was presented to the supervisor during the initial response phase.

[0051] In this case, too, the disaster-related information corresponding to the elapsed time information may be presented in a manner that allows the display to be switched using tabs or icons, as described above, or may be presented in a manner that automatically switches as time passes. In the example of FIG. 7, four pieces of disaster-related information are presented to the user, and are displayed in the same size within windows divided into a mesh pattern, but the present invention is not limited to this example. The number of pieces of disaster-related information to be presented can be set as appropriate. The disaster-related information may also be presented in different sizes and layouts. Furthermore, information other than the disaster-related information presented to the user according to the elapsed time information (for example, decision support information obtained by analyzing the disaster-related information) may be displayed together with the determined disaster-related information.

[0052] The above describes the decision support device 100 according to this embodiment and the decision support method using the same. According to this embodiment, the decision support device 100 calculates elapsed time information at the time when presentation information is presented to the user, and based on the calculated elapsed time information, presents to the user useful disaster-related information that is important when deciding on a disaster response at that current phase. The user can check important information for each phase of disaster response, allowing for faster and more appropriate understanding of the disaster situation and decision-making.

[0053] [4. Program] The program according to this embodiment may be a program that causes a computer to execute the functional units shown in Fig. 1 or 3. By installing and executing this program on a computer, the decision support device 100 and the decision support method according to this embodiment can be realized. In this case, the processor of the computer functions and processes as the elapsed time information output unit 110 and the determination unit 120 of the decision support device 100, as well as the reference time acquisition unit 130, the phase estimation unit 140, the disaster-related information acquisition unit 150, and the presentation processing unit 160.

[0054] In this embodiment, the storage unit 170 may be realized by storing the data files constituting the storage unit 170 in a storage device such as a hard disk provided in the computer, or may be realized by a storage device of another computer. Examples of the computer include a general-purpose PC, a smartphone, and a tablet terminal device.

[0055] Furthermore, the program according to this embodiment may be executed by a computer system constructed by a plurality of computers, in which case, for example, each computer may function as any one of the elapsed time information output unit 110, the determination unit 120, the reference time acquisition unit 130, the phase estimation unit 140, the disaster-related information acquisition unit 150, and the presentation processing unit 160.

[0056] [5.Physical configuration] The physical configuration of a computer that executes the program according to the above embodiment to realize the decision support device 100 will be described with reference to Fig. 8. Fig. 8 is a block diagram showing an example of a computer 900 that realizes the decision support device 100 according to this embodiment.

[0057] 8, a computer 900 includes a CPU (Central Processing Unit) 901, a main memory 902, a storage device 903, an input interface 904, a display controller 905, a data reader / writer 906, and a communication interface 907. These components are connected to each other via a bus 911 so as to be able to communicate data with each other.

[0058] Furthermore, the computer 900 may include a GPU (Graphics Processing Unit) or an FPGA (Field-Programmable Gate Array) in addition to or instead of the CPU 901. In this aspect, the GPU or FPGA can execute the programs in the above-described embodiments.

[0059] The CPU 901 loads a program in the embodiment, which is composed of a group of codes and stored in the storage device 903, into the main memory 902 and executes each code in a predetermined order to perform various calculations. The main memory 902 is typically a volatile storage device such as a DRAM (Dynamic Random Access Memory).

[0060] The program according to the above embodiment is provided in a state stored in a computer-readable recording medium 910. The program according to the above embodiment may be distributed over the Internet connected via the communication interface 907.

[0061] Specific examples of the storage device 903 include a hard disk drive and a semiconductor storage device such as a flash memory. The input interface 904 mediates data transmission between the CPU 901 and input devices 908 such as a keyboard and a mouse. The display controller 905 is connected to a display device 909 and controls the display on the display device 909.

[0062] The data reader / writer 906 mediates data transmission between the CPU 901 and the recording medium 910, reads programs from the recording medium 910, and writes processing results from the computer 900 to the recording medium 910. The communication interface 907 mediates data transmission between the CPU 901 and other computers.

[0064] The decision support device 100 according to the above embodiment can be realized by using hardware corresponding to each unit, rather than a computer on which a program is installed. Furthermore, part of the decision support device 100 may be realized by a program, and the remaining part may be realized by hardware.
