[Technical Field]

[0001] The present invention relates to a disaster countermeasure support device and a disaster countermeasure support method. [Background technology]

[0002] When natural disasters such as typhoons or earthquakes occur, facilities that make up public infrastructure (for example, communication facilities) may be damaged in a short period of time in multiple locations, causing numerous failures and making it impossible for operators to provide public services.

[0003] Against this background, technologies for quickly advancing or realizing recovery from natural disasters have been proposed. For example, Patent Document 1 discloses a recovery plan formulation device having a recovery priority calculation unit that calculates a recovery priority indicating the degree to which recovery should be prioritized for each facility based on the degree of damage to each facility when a crisis event occurs and a preset degree of impact on services when each facility is damaged, and a recovery plan formulation unit that formulates a recovery plan including resource allocation for restoring each facility based on the recovery priority of each facility calculated by the priority calculation unit.

[0010] Hereinafter, an embodiment of the present invention will be described. The disaster countermeasures support device 1 according to this embodiment supports the recovery measures of the business operator related to a public facility when the public facility in the public system is damaged by a disaster such as a typhoon, flood, or earthquake. The disaster countermeasures support device 1 provides information for the recovery measures in response to a request from an information processing device or the like (hereinafter referred to as a business operator terminal) managed by the business operator.

[0011] Public facilities in a public system are facilities or equipment that contribute to the public (so-called social infrastructure facilities or infrastructure), such as roads, flood control facilities, ports, railways, parks, water supply and sewerage systems, communication facilities, and energy supply facilities. In this embodiment, public facilities are assumed to be communication equipment in a communication system that is composed of multiple communication equipment. Telecommunications carriers provide communication services to residents, who are users, using multiple communication equipment. Here, in this embodiment, the communication equipment is mainly communication cables, but this is not intended to limit the type of communication equipment.

[0012] 1 is a diagram illustrating an example of main functions of the disaster countermeasure support device 1. The disaster countermeasure support device 1 includes the following functions: an information input unit 101, a disaster area estimation unit 102, a damaged facility correction unit 103, a priority element calculation unit 104, a priority calculation unit 105, a priority change unit 106, a priority correction unit 107, a parameter adjustment unit 108, a construction content proposal unit 109, and a priority display unit 110.

[0013] The information input unit 101 receives input of fault information (hereinafter referred to as communication fault information) from a user (in this embodiment, a telecommunications carrier) that includes location information of a user using a communication service and information on a fault report related to the user's service.

[0014] The information input unit 101 also receives input of damage information (hereinafter referred to as damaged facility information) from the user, including location information of damaged communication facilities (hereinafter referred to as damaged facilities) and information on the damage status of the communication facilities.

[0015] Furthermore, the information input unit 101 accepts input of disaster information (hereinafter referred to as disaster information) from the user, including information on the disaster area and information on the damage status of public facilities in the disaster area.

[0016] The disaster area estimation unit 102 estimates the area to which the disaster-stricken public facility belongs (hereinafter referred to as the disaster area) based on the location information of the users of the communication facilities in the communication failure information.

[0017] The priority element calculation unit 104 calculates an urgency indicating the degree of damage to the affected facility and an impact indicating the magnitude of the impact of the damage on other communication facilities, based on the affected facility estimated by the affected area estimation unit 102 and the damage information (damaged facility information and disaster information) input by the information input unit 101. The urgency and impact are composed of parameters associated with the state of the affected facility and weight values associated with the affected facility. Details of the urgency and impact will be described later.

[0018] In this embodiment, the priority element calculation unit 104 receives a selection of a calculation method for the urgency and impact from a plurality of calculation methods from the user via an input device, and calculates the urgency and impact based on the selected calculation method.

[0019] The priority calculation unit 105 calculates the priority (hereinafter referred to as provisional priority) of measures for affected public facilities based on the calculated urgency and impact and information indicating the reliability of the calculated values of urgency and impact (hereinafter referred to as reliability).

[0020] After calculating the provisional priority, the damaged facility correction unit 103 accepts corrections to the damaged facility information and disaster information from the user via the input device. For example, the damaged facility correction unit 103 corrects the damage information (damaged facility information and disaster information) based on information input by the user after conducting a field survey of the disaster area. Then, the priority calculation unit 105 recalculates the priority (hereinafter referred to as the final priority) based on the corrected information.

[0021] The priority change unit 106 determines whether the priorities of multiple affected equipment are the same among the calculated priorities, and if the priorities of multiple affected equipment are the same, it changes the priorities of the affected equipment based on the equipment-location information 170 described below (making the priority of one affected equipment lower than the priority of the other affected equipment).

[0022] The priority modification unit 107 further receives an input of a priority modification from the user via an input device.

[0023] The parameter adjusting unit 108 changes the parameters and weight values relating to the urgency and impact according to the corrected priority.

[0024] The construction content proposal unit 109 identifies countermeasures (construction content, etc.) for the damaged communication equipment based on the damaged equipment information corrected and input by the damaged equipment correction unit 103, and displays the identified countermeasures on the screen.

[0025] The priority display unit 110 displays information relating to the priority on the screen.

[0026] Next, the disaster countermeasure support apparatus 1 stores disaster related information 150, facility-line information 160, facility-location information 170, line-contract information 180, and business information 190.

[0027] The disaster-related information 150 includes communication failure information, damaged facility information, and disaster information. The disaster-related information 150 includes a damaged location management table 900, which will be described later.

[0028] The facility-line information 160 is configuration information of the communication system (information including the configuration of connections and links between communication facilities, and the configuration of customers (users) connected to each communication facility).

[0029] The facility-location information 170 is stored information that associates communication facilities, the locations of the communication facilities, and the regions to which the communication facilities belong. In this embodiment, the regions are specified by the jurisdictions of the respective business offices of the telecommunications carriers.

[0030] The line-contract information 180 is information that associates the communication equipment, the specific service content provided to each user via that communication equipment (in this embodiment, the type of communication line contract; for example, the type of line, such as a personal contract or a corporate contract), and the location information (address, etc.) of each user.

[0031] The business information 190 is information about the current operating status of each piece of communication equipment. The business information 190 also includes information about the team in charge of the restoration work on the communication equipment, information about the type of work, and the like.

[0032] 2 is a diagram illustrating an example of hardware included in the disaster countermeasure support apparatus 1. The disaster countermeasure support apparatus 1 includes a processing device 91 (processor) such as a CPU (Central Processing Unit), a DSP (Digital Signal Processor), a GPU (Graphics Processing Unit), or an FPGA (Field-Programmable Gate Array), a main memory device 92 such as a ROM (Read Only Memory) or a RAM (Random Access Memory), an auxiliary memory device 93 including a storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive), a communication device 94 including a NIC (Network Interface Card), a wireless communication module, a USB (Universal Serial Interface) module, or a serial communication module, an input device 95 including a mouse, a keyboard, or the like, and an output device 96 including a liquid crystal display, an organic EL (Electro-Luminescence) display, or the like.

[0033] The functions of each functional unit of the disaster countermeasure support apparatus 1 described above are realized by the processing device 91 of the disaster countermeasure support apparatus 1 reading out a predetermined program that realizes the function of each functional unit stored in the main memory device 92 or the auxiliary memory device 93. Each program can be recorded on a recording medium and distributed, for example. Note that the disaster countermeasure support apparatus 1 may be realized, in whole or in part, using virtual information processing resources provided using virtualization technology, process space separation technology, or the like, such as a virtual server provided by a cloud system. Furthermore, all or in part of the functions provided by the disaster countermeasure support apparatus 1 may be realized, for example, by a service provided by a cloud system via an API (Application Programming Interface) or the like. Next, the processing performed by the disaster countermeasure support device 1 will be described.

[0034] <Disaster response support processing> FIG. 3 is a flow diagram illustrating an outline of the disaster countermeasure support process executed by the disaster countermeasure support device 1. As shown in FIG. First, the disaster countermeasure support device 1 executes an information input process s10 for accepting input of disaster-related information 150 from a user (such as a business operator terminal). Details of the information input process s10 will be described later.

[0035] Then, the disaster countermeasure support device 1 executes a region estimation process s20 for estimating the region (disaster-affected region) to which the affected facility (disaster-affected facility) belongs, based on the disaster-related information 150 input in the information input process s10. The region estimation process s20 will be described in detail later.

[0036] The disaster countermeasures support device 1 also executes a provisional priority calculation process s30 to calculate a provisional priority of each affected facility based on the affected area, the urgency and impact calculated from the disaster-related information 150, the reliability, etc. Details of the provisional priority calculation process s30 will be described later. Then, the disaster countermeasures support device 1 displays the calculated provisional priority on the screen of the disaster countermeasures support device 1 or the operator terminal, etc.

[0037] Here, a person in charge of the telecommunications carrier or the like identifies the status of the affected facilities and the disaster situation in the affected area by conducting an on-site investigation of each affected facility and each disaster location in the affected area according to the displayed provisional priority. For example, the person in charge or the like may discover new affected facilities and disasters that have occurred in the affected area other than the affected facilities and disasters registered in the disaster-related information 150, or may discover an error in the information entered in the information input process s10.

[0038] Thereafter, the disaster countermeasure support apparatus 1 executes a damaged facility determination process s40 to correct the damage information (damaged facility information and disaster information) that is the result of the on-site investigation.

[0039] Specifically, for example, the disaster countermeasure support device 1 accepts input of corrections to the damaged facility information and disaster information from a person in charge or the like (such as a business operator terminal).

[0040] Then, the disaster countermeasure support device 1 executes a work content presentation process s50 for proposing the details of restoration work for the affected facilities to the person in charge of the work, based on the corrected disaster-related information 150. The work content presentation process s50 will be described in detail later.

[0041] The disaster countermeasure support device 1 also executes a priority calculation process s60 to calculate a formal priority based on the newly calculated urgency and impact from the corrected disaster-related information 150. The disaster countermeasure support device 1 calculates the formal priority using the same formula as the provisional priority calculated in the provisional priority calculation process s30. Details will be described later.

[0042] Then, the disaster countermeasure support device 1 executes a priority change process s70 to change the official priorities of the affected facilities having the same official priorities among the official priorities of the affected facilities calculated in the priority calculation process s60. The details of the priority change process s70 will be described later.

[0043] Furthermore, the disaster countermeasure support apparatus 1 executes a priority modification process s80 for receiving from the user an input of further modification to the official priority of each affected facility that was modified in the priority modification process s70. The priority modification process s80 will be described in detail later.

[0044] The disaster countermeasure support apparatus 1 executes a priority display process s90 for displaying information on the formal priority corrected by the priority correction process s80 on the disaster countermeasure support apparatus 1 or a business operator terminal, etc. For example, the disaster countermeasure support apparatus 1 displays a priority display screen 2300, which will be described later.

[0045] The disaster countermeasure support apparatus 1 executes a parameter adjustment process s100 for modifying the parameters and weight values related to the priority based on the formal priority modified in the priority modification process s80. The parameter adjustment process s100 will be described in detail later. Specific examples or details of each process will be described below.

[0046] <Information input processing> The screen displayed in the information input process s10 will be described. The disaster countermeasure support device 1 displays a disaster report information input screen 400 for inputting disaster-related information 150.

[0047] (Disaster report information entry screen) 4 is a diagram showing an example of a disaster report information input screen 400. The disaster report information input screen 400 includes a communication failure information input field 410 that displays a communication failure report input screen 500 that accepts input of communication failure information from the user, a damaged facility information input field 420 that displays a facility damage report input screen 600 that accepts input of damaged facility information from the user, and a disaster occurrence report input field 430 that displays a disaster occurrence report input screen 800 that accepts input of disaster information from the user.

[0048] (Communication failure report input screen) 5 is a diagram showing an example of a communication failure report input screen 500. The communication failure report input screen 500 includes a communication failure number setting field 510 for setting a number (failure report number) for reporting (reporting) a communication failure, a customer information setting field 520 for accepting input of identification information of a customer (user) of the telecommunications carrier from a user, a report content input field 530 for accepting input of the content of the communication failure report from the user from the user, a report date and time input field 540 for accepting input of the report date and time from the user, and a registration field 550 for accepting registration of the above setting content and input content in disaster-related information 150 from a user.

[0049] (Facility damage report entry screen) 6 is a diagram showing an example of a facility damage report input screen 600. The facility damage report input screen 600 includes a damaged facility selection field 610 (selectable by address and a map screen 700 described later) for accepting input of damaged facility, a damage situation input field 620 for accepting input of information on the status of the damaged facility, a damaged facility image data import field 630 for accepting reading of an image of the damaged facility, and a damage situation keyword candidate display field 640 for displaying candidates (related keywords) for the status of the damaged facility based on the image data read in the damaged facility image data import field 630 and accepting selection of the status.

[0050] The disaster countermeasures support device 1 performs the following process with respect to the damage situation keyword candidate display field 640. That is, the disaster countermeasures support device 1 performs a predetermined image recognition process on the image data of the damaged facility input into the damaged facility image data import field 630 (for example, inputting the image data into a trained model that outputs information on the condition (damage, tilt) of the damaged facility for the read image data of the damaged facility, or performing pattern matching with image data of the facility at the time of the disaster that has been prepared in advance), thereby estimating the condition of the damaged facility, and displays one or more related keyword candidates corresponding to the estimation result in the damage situation keyword candidate display field 640.

[0051] (Map screen) 7 is a diagram showing an example of a map screen 700. The map screen 700 includes a map display field 710 that displays a map read from a predetermined map database, and a facility display field 720.

[0052] Various communication facilities 712 are displayed in the map display field 710, and when the user specifies an area 711 in the map display field 710, information about the communication facilities 712 present in that area 711 is displayed in the facility display field 720. When the user selects a communication facility displayed in the facility display field 720, the communication facility is reflected in the damaged facility selection field 610 on the facility damage report input screen 600 or the damaged area selection field 810 on the disaster occurrence report input screen 800, which will be described later.

[0053] (Disaster occurrence report entry screen) 8 is a diagram showing an example of a disaster occurrence report input screen 800. The disaster occurrence report input screen 800 is an input screen similar to the facility damage report input screen 600. The disaster occurrence report input screen 800 includes a disaster area selection field 810 (selectable by address and the map screen 700) for accepting input of a disaster area, a disaster situation input field 820 for accepting input of information about the disaster situation, a disaster image data import field 830 for accepting loading of an image of the disaster situation, and a disaster situation keyword candidate display field 840 for displaying candidates for the disaster situation (related keywords) based on the image data loaded into the disaster image data import field 830.

[0054] When an area 711 is specified on the map screen 700 on the disaster occurrence report input screen 800, the disaster countermeasures support device 1 estimates future disaster-stricken facilities (future disaster-stricken facilities) as follows. That is, the disaster countermeasures support device 1 determines whether a disaster has been predicted for an area including the specified area 711 or for an area surrounding the area 711 (for example, by referring to a predetermined weather information database, it determines whether disaster prediction information has been set for the area). Then, when it determines that a disaster has been predicted, the disaster countermeasures support device 1 searches for facilities present in the area from the facilities displayed on the map screen 700. Then, the disaster countermeasures support device 1 stores the searched facilities as future disaster-stricken facilities. When an address is input in the disaster area selection field 810 on the disaster occurrence report input screen 800, the disaster countermeasures support device 1 may similarly search for and store future disaster-stricken facilities.

[0055] (Disaster area management table) 9 is a diagram showing an example of a disaster location management table 900, which is a table that stores disaster-affected facility information, etc. The disaster location management table 900 has the following data items: record number 901, disaster location 902 in which the location of the disaster-affected facility is set, location type 903 in which the type of disaster-affected facility is set, disaster cause 904 in which the cause of the disaster-affected facility (set based on disaster information corresponding to the location of the disaster-affected facility) is set, and disaster status 905 in which information on the status of the disaster-affected facility is set.

[0056] The affected area management table 900 may store communication failure information, affected facility information, and disaster information all together.

[0057] <Region estimation processing> Next, the area estimation process s20 will be described. 10 is a diagram illustrating an example of the area estimation process s20. As shown in the figure, the disaster countermeasure support device 1 identifies the location information of the user associated with the failure report number 610 of each communication failure input on the communication failure report input screen 500, based on the line-contract information 180. Then, based on each identified piece of location information and the facility-position information 170, the disaster countermeasure support device 1 identifies the affected facility 1010 corresponding to the location information.

[0058] Then, the disaster countermeasure support apparatus 1 stores a plurality of pieces of communication failure information 1021 relating to the same damaged facility 1011 in association with the damaged facility 1011. The disaster countermeasure support apparatus 1 sets the same damage management number 1031 (identifier) for the damaged facility 1011.

[0059] As a result, the disaster countermeasure support device 1 can collectively handle a plurality of pieces of communication failure information relating to the same damaged facility 1011.

[0060] Next, the disaster countermeasures support device 1 identifies damaged facilities that belong to the same area. The disaster countermeasures support device 1 aggregates the damage management numbers of multiple damaged facilities that belong to the same area (for example, the same geographical area or the same communication system) into the same damage management number, and stores information on the damaged facilities with that damage management number in a damaged facility management table 1100, which will be described later.

[0061] For example, the disaster countermeasure support device 1 aggregates information based on the geographical relationship of the affected facilities. Specifically, the disaster countermeasure support device 1 classifies affected facilities in the same area as the same region based on the facility-location information 170. Then, the disaster countermeasure support device 1 sets one of the affected facilities belonging to the same region as a representative facility of the region (hereinafter referred to as representative facility). The disaster countermeasure support device 1 may accept the selection of the representative facility from the user, or may set it automatically.

[0062] The disaster countermeasure support device 1 calculates the priority only for representative equipment. As a result, when there are many pieces of damaged equipment, it is only necessary to calculate the priority for only the equipment necessary for taking measures against a disaster, which improves processing efficiency and enables faster support for disaster countermeasures.

[0063] Furthermore, for example, the disaster countermeasure support apparatus 1 aggregates information based on the communication system to which the affected facilities belong. Specifically, based on the facility-line information 160, the disaster countermeasure support apparatus 1 classifies affected facilities related to the same type of communication line in the same system (for example, classified into trunk lines, sub-trunk lines, or terminal communication cables connected to consumers) as the same area. Then, the disaster countermeasure support apparatus 1 sets one of the affected facilities belonging to the same area as a representative facility for that area. The disaster countermeasure support apparatus 1 may accept the selection of the representative facility from the user, or may set it automatically.

[0064] As described above, the disaster countermeasure support device 1 can collectively handle damaged facility information relating to multiple damaged facilities in the same area. Here, a specific example of the damaged facility management table 1100 will be described.

[0065] (Damaged equipment management table) 11-13 shows examples of a damaged-equipment management table created by the area estimation process s20. The damaged-equipment management table 1100 includes the following data items: a damage management number 1101, which sets the damage management number of the damaged equipment; a representative equipment flag 1102, which sets information indicating that the damaged equipment is a representative equipment if the damaged equipment is a representative equipment; a damaged-equipment number 1103, which sets the number of the damaged equipment; an equipment type 1104, which sets the type of the damaged equipment; an equipment ID 1105, which sets an identifier for the type and individual of the damaged equipment; a related damaged-equipment number 1106, which sets an identifier for a damaged equipment (related damaged equipment) related to the damaged equipment; a current priority 1107, which sets the current priority; a future priority 1108, which sets the future priority; a determination flag 1109, which sets a determination flag indicating whether the official priority value has been calculated; and an investigation flag 1110, which sets an investigation flag indicating whether the above-mentioned on-site investigation of the damaged equipment has been performed. The related damaged equipment may be specified by a user or may be automatically set by the disaster countermeasure support device 1 based on the equipment-line information 160, etc. It should be noted that the current priority 1107, future priority 1108, and final flag 1109 are set in the priority calculation process s60, for example.

[0066] <Provisional priority calculation process, priority calculation process> Next, the provisional priority calculation process s30 and the priority calculation process s60 will be described. Note that the priority calculation process s60 calculates provisional priorities in the same manner as the provisional priority calculation process s30. Therefore, the final priority and provisional priority will be collectively referred to as "priority" here, and the description of the provisional priority calculation process s30 and the priority calculation process s60 will also be included.

[0067] (Priority calculation formula editing screen) 14 and 15 are diagrams showing examples of priority calculation formula editing screens displayed in the provisional priority calculation process s30 and the priority calculation process s60.

[0068] 14 accepts input of a priority calculation formula from a user. Specifically, the priority calculation formula editing screen 1400 includes a priority calculation formula editing field 1410, a reliability editing field 1420, an urgency calculation formula addition field 1430, an impact calculation formula addition field 1440, and a calculation formula editing field 1450.

[0069] The priority calculation formula editing field 1410 accepts input of one or more types of urgency (urgency 1, urgency 2, urgency 3, ...) added in the urgency calculation formula addition field 1430, one or more types of impact (impact 1, impact 2, impact 3, ...) added in the impact calculation formula addition field 1440, and an operator (for example, an addition operator, a multiplication operator). A user can create and register any calculation formula for priority by using the priority calculation formula editing field 1410. Then, the disaster countermeasure support apparatus 1 calculates the priority by multiplying the value of the registered calculation formula by the reliability.

[0070] The calculation formula registered in the priority calculation formula editing field 1410 consists of one or more terms, and is a calculation formula for the total value of each term consisting of, for example, a term of the multiplication value of urgency and impact, a term of urgency only, or a term of impact only.

[0071] The reliability edit field 1420 accepts input of the reliability from the user. For example, the user sets a low value before conducting a field survey, and a high value after conducting the field survey.

[0072] The calculation formula edit field 1450 receives input from the user of the calculation method (calculation formula) for the urgency or impact selected in the urgency calculation formula addition field 1430 or the impact calculation formula addition field 1440 .

[0073] In the calculation formula editing field 1450, the user specifies the calculation formula for the urgency or impact level by SQL that operates the database that records the disaster-related information 150 such as the disaster area management table 900.

[0074] On the other hand, the priority calculation formula editing screen 1500 shown in Fig. 15 has a configuration similar to the priority calculation formula editing screen 1500 shown in Fig. 14. However, on this priority calculation formula editing screen 1500, the user specifies the calculation formula for the urgency or impact level by using a conditional expression for each piece of data in a database 1501 that records disaster-related information 150 such as the disaster area management table 900.

[0075] Here, a specific example of a calculation method (calculation formula) for the urgency level set on the priority calculation formula editing screens 1400 and 1500 will be described.

[0076] (Urgency) 16 is a diagram showing an example of a method for calculating the degree of urgency. When a related keyword 1601 (for example, damage details that require immediate action, such as bending of communication lines or collapsed utility poles) is set in the damage cause 904 and the damage status 905 of the damage location management table 900 for the damaged facility, this degree of urgency (first degree of urgency) is calculated from the value of the secondary disaster occurrence degree 1602, which is a parameter corresponding to the related keyword 1601.

[0077] 17 is a diagram showing another example of a method for calculating the degree of urgency. This degree of urgency (second degree of urgency) is calculated for the affected equipment by a weight value 1702 associated with the number of days 1701 that have passed since the occurrence of the corresponding disaster.

[0078] 18 is a diagram showing another example of a method for calculating the degree of urgency. This degree of urgency (third degree of urgency) is calculated by multiplying the value of the parameter corresponding to the case, ie, the degree of ease of countermeasure 1803, by the weight value 1804, when there is a communication network (current detour route) that allows the telecommunications carrier to provide communication services to users using communication facilities other than the affected facility when the affected facility is not in operation (presence of current detour route 1801) and the current detour route is usable (usability of current detour route 1802).

[0079] The disaster countermeasure support apparatus 1 can calculate the current detour route existence 1801 based on the facility-line information 160, for example, and calculate the current detour route availability 1802 based on the business information 190.

[0080] 19 is a diagram showing another example of a method for calculating the degree of urgency. When a reporting obligation 1901 (for example, a procedure required of a specific department, such as reporting a crack in the ground or a collapse of a levee) is set in the damage cause 904 and the damage status 905 of the damage location management table 900 for the damaged facility, this degree of urgency (fourth degree of urgency) is calculated from a weight value 1903 associated with a deadline 1902, which is a parameter indicating the deadline for the procedure associated with the reporting obligation 1901.

[0081] 20 is a diagram showing another example of a method for calculating the degree of urgency. When there is another business operator that manages equipment that cooperates with or is connected to the affected facility (other company coordination 2001), this degree of urgency (fifth degree of urgency) is calculated based on the value of the parameter "other company coordination presence / absence" 2002 associated with that business operator.

[0082] Next, a specific example of a method (calculation formula) for calculating the influence degree will be described.

[0083] 21 is a diagram showing an example of a method for calculating the degree of impact. This urgency (first degree of impact) is calculated from any one of a currently affected number of households 2101, which is a parameter of the number of users (number of consumer households) who used other communication facilities (for example, communication facilities downstream of the affected facility) that were linked with the affected facility at the time of the disaster, a future affected number of households 2102, which is a parameter of the number of users (number of consumer households) who use other communication facilities (for example, communication facilities downstream of the future affected facility) that are linked with communication facilities that are predicted to be affected at a predetermined future point in time after the disaster (the above-mentioned future affected facility), and an average value 2103 of the currently affected number of households 2101 and the future affected number of households 2102.

[0084] The disaster countermeasures support device 1 can calculate the current number of affected households 2101 based on the facility-line information 160. The disaster countermeasures support device 1 can also calculate the future number of affected households 2102 based on the future damaged facilities calculated on the disaster occurrence report input screen 800 and the facility-line information 160. The disaster countermeasures support device 1 may also calculate, as the first urgency, a pro rata value based on each weight value associated with each of the current number of affected households 2101 and the future number of affected households 2102, rather than the average value of the current number of affected households 2101 and the future number of affected households 2102.

[0085] 22 is a diagram showing another example of a method for calculating the impact. This urgency (second impact) is calculated for the affected facility using a weight value 2202 according to the proportion of corporate contracts among all users of the affected facility (corporate line occupancy rate 2201). The disaster countermeasure support apparatus 1 can calculate this weight value 2202 based on the facility-line information 160 and line-contract information 180.

[0086] Here, when an urgency or impact including future data is set in the priority calculation formula editing field on the priority calculation formula editing screen, the disaster countermeasure support device 1 may calculate the current priority and the future priority. For example, when "impact 1" (first impact) is set in the priority calculation formula editing field, the disaster countermeasure support device 1 calculates the current priority based on the current number of affected households 2101, and also calculates the future priority based on the future number of affected households 2101 or the average value 2103.

[0087] (Priority display screen) 23 is a diagram showing an example of a priority display screen 2300 displayed in the provisional priority calculation process s30 and the priority calculation process s60. The priority display screen 2300 displays priority information for each damage management number. Specifically, the priority display screen 2300 displays information such as a damage management number 2301, a priority 2302 (official priority or provisional priority) related to the damaged equipment of the damage management number 2301, a construction location 2303 (or area) of the damaged equipment, a construction type 2304 of the damaged equipment, and a construction team 2305 for the damaged equipment.

[0088] The construction location 2303, construction type 2304, and construction team 2305 are identified by, for example, the business information 190 or the facility-location information 170.

[0089] The display order of priorities on the priority display screen 2300 may be the order in which the priorities are calculated, or may be the order based on the values of other items, or may be changeable by the user. In addition, the user may be able to arbitrarily specify the information on the construction location 2303, construction type 2304, or construction team 2305 to be displayed on the priority display screen 2300.

[0090] Furthermore, the disaster countermeasures support device 1 may not only display the priority values on the screen, but also display a map on the screen and display each affected facility and its priority on the map. In this case, the disaster countermeasures support device 1 may also display information on the current priority and future priority on the map. This allows the user to plan a future disaster recovery schedule with a clear view.

[0091] The disaster countermeasure support device 1 does not calculate the priority of all affected facilities, but calculates the priority only for affected facilities that are set as representative facilities in the affected facility management table 1100. Furthermore, the disaster countermeasure support device 1 does not calculate the priority of all types of affected facilities, but calculates the priority only for a predetermined type of affected facility (for example, a cable) in the affected facility management table 1100.

[0092] <Construction content presentation processing> 24 is a flow diagram illustrating the details of the work content presentation process s50. Here, the process for a certain damaged facility with a high provisional priority will be described.

[0093] The disaster countermeasure support device 1 determines whether or not there is a communication facility configuration (detour route) that enables communication services to be provided to each user by other communication facilities excluding the damaged facility (s51). For example, the disaster countermeasure support device 1 determines whether or not there is a detour route by the process described for the third urgency level.

[0094] If there is a detour route (s51: Yes), the disaster countermeasure support apparatus 1 executes the process of s52, and if there is no detour route (s51: No), the disaster countermeasure support apparatus 1 executes the process of s56.

[0095] In s52, the disaster countermeasure support apparatus 1 determines whether or not the detour route is currently available. For example, the disaster countermeasure support apparatus 1 determines whether or not the detour route is currently available by the process described in the third urgency level.

[0096] If the detour route is currently available (s52: available), the disaster countermeasure support device 1 executes the process of s53, and if the detour route is currently not available (s52: no), the disaster countermeasure support device 1 executes the process of s58.

[0097] In s53, the disaster countermeasure support apparatus 1 determines the necessity and possibility of reinforcing the detour route. For example, the disaster countermeasure support apparatus 1 may determine the necessity and possibility of reinforcing the detour route based on information about the damaged facilities registered in the damaged area management table 900 (e.g., the damage cause 904 and the damage situation 905), or may accept information input from the user about the necessity and possibility of reinforcing the detour route.

[0098] If reinforcement of the detour route is necessary but possible (s53: necessary, possible), the disaster countermeasures support device 1 executes the processing of s54, if reinforcement of the detour route is not necessary (s53: not necessary), the disaster countermeasures support device 1 executes the processing of s55, and if reinforcement of the detour route is necessary but not possible (s53: necessary, not possible), the disaster countermeasures support device 1 executes the processing of s58.

[0099] In s54, the disaster countermeasure support device 1 executes a detour route calculation process, which will be described later, and displays information indicating that the detour route should be reinforced on the screen, and the work content presentation process s50 ends.

[0100] In s55, the disaster countermeasure support device 1 displays on the screen information indicating that there is no need to reinforce the detour route, and the construction content presentation process s50 ends.

[0101] On the other hand, in s56, the disaster countermeasures support apparatus 1 determines whether or not it is possible to restore the damaged facility. For example, the disaster countermeasures support apparatus 1 may determine whether or not it is possible to restore the damaged facility based on information about the damaged facility registered in the damaged location management table 900 (for example, the cause of damage 904 and the damage situation 905), or may receive an input from the user as to whether or not it is possible to restore the damaged facility.

[0102] If it is possible to restore the affected equipment (s56: Yes), the disaster prevention support device 1 executes the processing of s57, and if it is not possible to restore the affected equipment (s56: No), the disaster prevention support device 1 executes the processing of s58.

[0103] In s57, the disaster countermeasure support device 1 executes a detour route calculation process, which will be described later, and displays information indicating that the damaged facilities should be restored on the screen, and the work content presentation process s50 ends.

[0104] In s58, the disaster countermeasure support device 1 executes a detour route calculation process, which will be described later, and displays information indicating that a new detour route should be constructed on the screen, and the construction content presentation process s50 ends.

[0105] <Detour route calculation process> 25 is a flow diagram illustrating the details of the detour route calculation process. The disaster countermeasure support device 1 determines whether it is possible to construct a detour route using existing communication facilities (s51). For example, the disaster countermeasure support device 1 determines whether it is possible to construct a detour route using existing communication facilities based on the facility-line information 160.

[0106] If it is possible to construct a detour route using existing communication facilities (s511: Possible), the disaster prevention support device 1 displays information on the screen indicating that specified communication disconnection and connection work should be carried out (s513), and the detour route calculation process s51 ends.

[0107] If it is impossible to construct a detour route using existing communication facilities (s511: No), the disaster prevention support device 1 displays information on the screen indicating that construction work to lay a new cable should be carried out (s512), and the detour route calculation process s51 ends.

[0108] <Priority change process> Next, the priority change process s70 will be described. 26 is a diagram showing an example of facility-line information 160 for explaining the priority change process s70. The communication system indicated by this facility-line information 160 includes a trunk line 2602 extending from an upstream communication station 2601, a first sub-trunk line 2604 branching from the trunk line 2602 at a first branch point 2603, a second sub-trunk line 2606 branching from the trunk line 2602 at a second branch point 2605 downstream of the first branch point 2603, and a third sub-trunk line 2608 branching from a third branch point 2607 of the second sub-trunk line 2606. The priorities of the first affected facility 2609, which is located midway downstream from the second branch point 2605 of the trunk line 2602, the second affected facility 2610, which is located at the end of the first sub-trunk line 2604, and the third affected facility 2611, which is located between the second branch point 2605 and the third branch point 2607 of the second sub-trunk line 2606 and is located in two adjacent areas, are each assumed to be 30.

[0109] In this case, the disaster countermeasures support device 1 integrates the two third damaged facilities 2611 into damaged facilities with the same damage management number, and manages only one of the damaged facilities in terms of priority processing. In this way, the disaster countermeasures support device 1 manages multiple damaged facilities that are geographically or systematically adjacent or close to each other as the same damaged facility in terms of priority processing, so that measures can be taken for these damaged facilities simultaneously.

[0110] Furthermore, the disaster countermeasure support device 1 changes the priority of the first affected facility 2609 to be higher than the priority of the third affected facility 2611 that has been reconfigured into the same affected facility, and changes the priority of the second affected facility 2610 to be higher than the priority of the third affected facility 2611. In this way, for affected facilities with the same priority, the disaster countermeasure support device 1 changes the priority of the affected facility with fewer downstream communication facilities to be higher. By increasing the priority of affected facilities with fewer affected communication facilities (or users), users can prioritize affected facilities that are expected to have an immediate recovery effect through recovery work. Note that the priority adjustment described here is just an example, and for example, the reverse order of the order described here may also be used.

[0111] 27 is a diagram showing an example of the damaged facility management table 1100 for explaining the priority change process s70. As shown in the figure, the disaster countermeasures support apparatus 1 refers to the facility-line information 160, etc., and identifies from the damaged facility management table 1100 that the area of the damaged facility group 2701 with the damage management number "7" is adjacent to the area of the damaged facility 2702 with the damage management number "25". The disaster countermeasures support apparatus 1 then integrates the damaged facility group 2701 and the damaged facility 2702, and creates a damaged facility management table 1100 that is reconstructed into a damaged facility group 2703 with the damage management number "7".

[0112] The above-described priority change process s70 is merely an example, and there are various possible methods for integrating affected facilities and changing the priority order.

[0113] <Priority correction processing, parameter adjustment processing> Next, the priority modification process s80 and the parameter adjustment process s100 will be described.

[0114] 28 is a diagram showing an example of a priority modification screen 2800 displayed in the priority modification process s80. The priority modification screen 2800 is a screen that uses a scatter diagram 2803 to show the relationship between a total priority 2801 calculated using all the urgency and impact levels for each affected facility and a designated priority 2802 calculated using only the urgency or impact levels input on the priority calculation formula editing screens 1400 and 1500. The user can move the position of the affected facility 2804 on the scatter diagram 2803 (reference numeral 2805). As a result, the disaster countermeasure support apparatus 1 stores the changed priority of the affected facility 2804.

[0115] Then, in the parameter adjustment process s100, the disaster countermeasure support apparatus 1 changes the parameters or weight values relating to the urgency or impact, which are the basis for calculating the priority, in accordance with the changed priority.

[0116] For example, the disaster countermeasure support apparatus 1 may search for a parameter value or weight value for the urgency or impact that will calculate the changed priority. Furthermore, for example, the disaster countermeasure support apparatus 1 may calculate a change value for the parameter or weight value by inputting the changed priority into a trained model that has undergone machine learning using the history of priority changes (the user's history of changes on the priority correction screen 2800) as learning data. Furthermore, the disaster countermeasure support apparatus 1 may display a screen that prompts the user to change the calculation formula for the urgency or impact.

[0117] FIG. 29 is a diagram showing an example of a priority correction screen 2900 when a designated priority based on the current number of affected households 2101 (first degree of influence) is designated as the designated priority. As shown in the figure, in the scatter diagram 2903 of this priority correction screen 2900, the designated priorities for the damage management numbers "3" and "5" are the same, but the overall priority for the damage management number "3" is much higher than the overall priority for the damage management number "5." Therefore, the user or the disaster countermeasure support device 1 may use the priority correction screen 2900 to change the weight values for parameters other than the first degree of influence. Alternatively, by referring to the entire scatter diagram 2903, the user may determine that the damage management number "3" may be an outlier due to some factor other than the current number of affected households. Furthermore, its overall priority is extremely low compared to the designated priority of the damaged facility with the damage management number "6." Therefore, the user or the disaster countermeasure support device 1 may consider changing the weight value related to the first impact degree (here, the current number of affected households 2101) using the priority modification screen 2900.

[0118] FIG. 30 shows an example of a priority modification screen 3000 when a priority based on the secondary disaster occurrence degree 1602 (first urgency) is specified as the designated priority. As shown in FIG. 30, in this scatter diagram 3003, the overall priority of the damaged facility with the damage management number "2" related to the related keyword "slope" is extremely high. Therefore, the user or the disaster countermeasures support device 1 may lower the weight value (here, the secondary disaster occurrence degree 1602) related to the related keyword "slope." Furthermore, the damaged facility with the damage management number "1" has a low possibility of secondary damage and a low number of future affected households, but its overall priority is high. Therefore, the user or the disaster countermeasures support device 1 may change parameters other than the secondary disaster occurrence degree 1602 and the number of future affected households 2012 and the corresponding weight values.

[0119] In this way, the parameter adjustment process s100 allows the user to fine-tune the priorities based on their own knowledge when the user feels uneasy about the priorities calculated by the disaster countermeasure support device 1 using a predetermined algorithm, thereby enabling the user to take more practical disaster countermeasures.

[0120] As described above, the disaster prevention support device 1 of this embodiment estimates the affected area based on the user's location information in the communication failure information, which is the report information, identifies the affected equipment based on the affected area, calculates the urgency and impact of the affected equipment based on the affected equipment and damage information (damaged equipment information and disaster information), and calculates the priority of the affected equipment based on the urgency, impact, and reliability, and displays the information.

[0121] That is, the disaster countermeasure support device 1 calculates the urgency and impact of a disaster based on failure information and disaster information from users collected from telecommunications carriers, etc., and further calculates the priority of countermeasures by taking reliability into account.

[0122] In this way, the disaster countermeasure support device 1 of this embodiment can effectively utilize collected information to support the formulation of countermeasures against disasters.

[0123] Furthermore, after calculating the provisional priority, the disaster countermeasure support device 1 of this embodiment accepts a correction to the damage information from the user, and recalculates the priority based on the corrected damage information.

[0124] This allows, for example, the user to conduct an on-site survey of the disaster area or the affected facilities based on the provisional priorities, and the disaster countermeasure support apparatus 1 to calculate more accurate priorities based on the results of the on-site survey.

[0125] In addition, the disaster prevention support device 1 of this embodiment calculates the urgency of the affected equipment based on the damage status of the affected equipment, the elapsed time since the disaster occurred, detour routes using communication equipment other than the affected equipment, the deadline for the affected equipment, or the extent of the impact on other communication equipment connected to the affected equipment.

[0126] This allows the disaster countermeasure support device 1 to calculate the degree of urgency in accordance with the disaster situation and the operational situation.

[0127] Furthermore, the disaster countermeasure support device 1 of this embodiment calculates the degree of influence of the damaged facility based on the number of affected households based on the damaged facility or based on whether or not there are other carriers cooperating with the telecommunications carrier.

[0128] This allows the disaster countermeasure support device 1 to calculate the degree of urgency according to the configuration of the communication system and other systems.

[0129] Furthermore, the disaster countermeasure support device 1 of this embodiment accepts a selection of a calculation method for urgency and impact from a user from a plurality of calculation methods for urgency and impact, and calculates the urgency and impact based on the selected calculation method.

[0130] This allows the disaster countermeasure support device 1 to calculate the urgency and impact based on the disaster situation and the operational situation.

[0131] Furthermore, the disaster countermeasure support device 1 of this embodiment estimates future damaged facilities based on the damage information and the facility-line information 160, and calculates the future impact based on the estimated damaged facilities.

[0132] This makes it possible to calculate priorities that take into account potential future disasters or secondary disasters depending on the status of the communication system.

[0133] Furthermore, the disaster countermeasure support apparatus 1 of this embodiment accepts input of corrections to the calculated priorities from the user.

[0134] This allows the user to take practical disaster countermeasures by appropriately correcting the priorities when the user empirically determines that the calculated priorities are incorrect.

[0135] Furthermore, the disaster countermeasure support device 1 of this embodiment changes the weight value relating to the urgency or the impact in accordance with the corrected priority.

[0136] This allows the disaster countermeasure support apparatus 1 to calculate more practical priorities.

[0137] Furthermore, if the calculated priorities of a plurality of communication facilities are the same, the disaster countermeasure support apparatus 1 of this embodiment changes the priority of the communication facility based on the facility-line information 160.

[0138] This allows the user to implement recovery measures by clearly prioritizing each affected facility.

[0139] Although the embodiments of the present invention have been described above, the description of the embodiments is intended to facilitate understanding of the present invention and is not intended to limit the present invention. The present invention may be modified or improved without departing from the spirit thereof, and the present invention includes equivalents thereof.

[0140] For example, some of the functional units of the information processing device in this embodiment may be other functional units, or multiple functional units may be integrated into one functional unit.

[0141] Furthermore, the calculation formulas for the urgency and impact explained in this embodiment are merely examples, and various types of calculation formulas are possible.

[0142] Furthermore, in this embodiment, a case where a communication infrastructure is affected by a disaster has been described, but the present invention can also be applied to infrastructure other than communication infrastructure in the same manner. [Explanation of symbols]
