This level of urgency (first level of urgency) is based on keywords 1601 (for example, sagging communication lines or collapsed utility poles) that require immediate countermeasures for the cause of damage 904 and the status of damage 905 in the disaster area management table 900 for the disaster-affected equipment. When a certain disaster damage content.) is set, it is determined by the value of the secondary disaster occurrence degree 1602, which is a parameter corresponding to the related keyword 1601.

FIG. 17 is a diagram illustrating another example of a method for calculating the degree of urgency. This degree of urgency (second degree of urgency) is determined by the weight value 1702 associated with the number of days 1701 that has passed since the date of occurrence of the corresponding disaster with respect to the disaster-affected facility.

FIG. 18 is a diagram illustrating another example of a method for calculating the degree of urgency. This degree of urgency (third degree of urgency) is based on the communication network that allows the telecommunications carrier to provide communication services to users using communication equipment other than the disaster-affected equipment if the disaster-affected equipment is not operational. If a current detour route exists (current detour route presence/absence 1801) and the current detour route is usable (current detour route availability 1802), the countermeasure ease level 1803 is a parameter associated with that case. It is determined by multiplying the value by the weight value 1804 associated with that case.

The disaster countermeasure support device 1 can calculate the presence or absence of a current detour route 1801 based on the equipment-line information 160, and can calculate the availability of the current detour route 1802 based on the business information 190, for example.

FIG. 19 is a diagram illustrating another example of a method for calculating the degree of urgency. This level of urgency (fourth level of urgency) indicates that regarding the disaster-affected equipment, reporting obligation 1901 (for example, reporting of ground cracks or levee collapses) is required to be carried out in the cause of damage 904 and damage situation 905 of the disaster area management table 900. ) is set, it is determined by the weight value 1903 associated with the deadline 1902, which is a parameter indicating the deadline of the procedure associated with this.

FIG. 20 is a diagram illustrating another example of the method for calculating the degree of urgency. This level of urgency (fifth level of urgency) is determined when there is another business operator that manages equipment that is linked or connected to the disaster-affected facility (Other Company Coordination 2001). It is determined based on the value of the associated parameter 2002, 2002, 2002, 2002, 2002.

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

FIG. 21 is a diagram illustrating an example of a method for calculating the degree of influence. This degree of urgency (first degree of impact) is determined by the number of users who were using other communication equipment (for example, communication equipment downstream of the affected equipment) that was linked to the affected equipment at the time of the disaster. The current number of affected households 2101, which is a parameter of the number of customer households), and other communication equipment (e.g. , the number of future affected units 2102 which is a parameter of the number of users (number of consumer units) who will use the communication equipment downstream of the disaster-affected facility in the future), or the average value 2103 of the current number of affected units 2101 and the future number of affected units 2102. It is determined by

Note that the disaster countermeasure support device 1 can calculate the current number of affected households 2101 based on the equipment-line information 160. Further, the disaster countermeasure support device 1 can calculate the future number of affected households 2102 based on the future disaster-affected equipment calculated on the disaster occurrence report input screen 800 and the equipment-line information 160. In addition, the disaster countermeasure support device 1 may calculate, as the first degree of urgency, a prorated value based on each weight value associated with each, instead of the average value of the current number of affected households 2101 and the future number of affected households 2102. .

FIG. 22 is a diagram illustrating another example of a method for calculating the degree of influence. This degree of urgency (second degree of influence) is determined by a weight value 2202 corresponding to the proportion of corporate contracts (corporate line occupancy rate 2201) of all users related to the disaster-affected facility. Note that the disaster countermeasure support device 1 can calculate this weight value 2202 based on the equipment-line information 160 and the line-contract information 180.

Here, if the degree of urgency or degree of impact including future data is set in the priority calculation formula editing field of the priority calculation formula editing screen, the disaster countermeasure support device 1 calculates the current priority and future priority. It may be calculated. For example, if "Impact level 1" (first impact level) is set in the priority calculation formula editing column, the disaster countermeasure support device 1 calculates the current priority based on the current number of affected households 2101, and The future priority is calculated based on the number of future affected houses 2101 or the average value 2103.

(Priority display screen)
Next, FIG. 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 disaster management number. Specifically, the priority display screen 2300 displays a disaster management number 2301, a priority 2302 (official priority or provisional priority) related to the damaged equipment of the disaster management number 2301, a construction location 2303 (or area) of the damaged equipment, Information about the construction type 2304 of the disaster-affected facility and the team 2305 in charge of construction of the disaster-stricken facility is displayed.

Note that the construction location 2303, construction type 2304, and construction team 2305 are specified by, for example, the work information 190 or the equipment-location information 170.

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

In addition to displaying the priority values on the screen, the disaster countermeasure support device 1 may display a map on the screen, and display each disaster-stricken facility and its priority on the map. Furthermore, in this case, the disaster countermeasure support device 1 may display information on the current priority and future priority on the map. This allows the user to clearly plan future schedules for disaster recovery.

Note that the disaster countermeasure support device 1 does not calculate the priorities of all disaster-affected facilities, but calculates the priorities only for the disaster-affected facilities set as representative facilities in the disaster-affected facility management table 1100. Furthermore, the disaster countermeasure support device 1 does not calculate the priorities of all types of disaster-affected equipment, but only assigns priorities to predetermined types of disaster-stricken equipment (for example, cables) in the disaster-affected equipment management table 1100. calculate.

<Construction details presentation process>
Next, FIG. 24 is a flow diagram illustrating details of the construction content presentation process s50. Here, processing for a certain disaster-affected facility that had a high provisional priority will be described.

The disaster countermeasure support device 1 determines whether there is a configuration of communication equipment (detour route) that allows communication services to be provided to each user using communication equipment other than the disaster-affected equipment (s51). For example, the disaster countermeasure support device 1 determines whether there is a detour route using the process described for the third level of urgency.

If there is a detour route (s51: Yes), the disaster prevention support device 1 executes the process of s52, and if there is no detour route (s51: No), the disaster prevention support device 1 executes the process of s56. do.

In s52, the disaster countermeasure support device 1 determines whether a detour route is currently available. For example, the disaster countermeasure support device 1 determines whether or not a detour route is currently available using the process described for the third level of urgency.

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

In s53, the disaster countermeasure support device 1 determines the necessity and possibility of reinforcement of the detour route. For example, the disaster countermeasure support device 1 determines the necessity and possibility of reinforcing the detour route based on the information of the disaster-affected equipment registered in the disaster-stricken location management table 900 (for example, the cause of the disaster 904 and the disaster situation 905). Alternatively, information input regarding the necessity and possibility of reinforcing the detour route may be accepted from the user.

If reinforcement of the detour route is necessary and possible (s53: required, possible), the disaster countermeasure support device 1 executes the process of s54, and if reinforcement of the detour route is not necessary (s53: unnecessary). , the disaster countermeasure support device 1 executes the process of s55, and if reinforcement of the detour route is necessary but impossible (s53: required or not), the disaster countermeasure support device 1 executes the process of s58.

In s54, the disaster countermeasure support device 1 executes a detour route calculation process to 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.

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

On the other hand, in s56, the disaster countermeasure support device 1 determines whether it is possible to restore the disaster-affected equipment. For example, the disaster countermeasure support device 1 determines whether or not it is possible to restore the disaster-stricken equipment based on information about the disaster-stricken equipment registered in the disaster-stricken location management table 900 (for example, the cause of the disaster 904 and the disaster situation 905). It may be determined, or an input may be received from the user as to whether or not it is possible to restore the disaster-affected equipment.

If it is possible to restore the disaster-affected equipment (s56: OK), the disaster countermeasure support device 1 executes the process of s57, and if it is not possible to restore the disaster-stricken equipment (s56: No). , the disaster countermeasure support device 1 executes the process of s58.

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 disaster-affected equipment should be restored on the screen, and the work content presentation process s50 ends.

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

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

If it is possible to construct a detour route using existing communication equipment (s511: OK), the disaster prevention support device 1 displays information on the screen indicating that predetermined communication disconnection and connection work should be performed. (s513), and the detour route calculation process s51 ends.

If it is impossible to construct a detour route using existing communication equipment (s511: No), the disaster prevention support device 1 displays information on the screen indicating that construction work to install a new cable should be performed. (s512), the detour route calculation process s51 ends.

<Priority change processing>
Next, the priority change process s70 will be explained.
FIG. 26 is a diagram showing an example of equipment-line information 160 for explaining the priority change process s70. The communication system indicated by this equipment-line information 160 includes a main line 2602 from an upstream communication station 2601, a first sub-main line 2604 that branches from the main line 2602 at a first branch point 2603, and a sub-main line 2604 that branches from the main line 2602 at a first branch point 2603. It is configured to include a second sub-trunk line 2606 that branches from the main line 2602 at a second branch point 2605, and a third sub-trunk line 2608 that branches from the third branch point 2607 of the second sub-trunk line 2606. Then, the first disaster-affected facility 2609 provided halfway downstream from the second branch point 2605 of the main line 2602, the second disaster-affected facility 2610 provided at the end of the first sub-main line 2604, and the second sub-main line 2606. It is assumed that the priority of the third disaster-affected facilities 2611 in two mutually adjacent areas, which are provided between the second branch point 2605 and the third branch point 2607, is 30.

In this case, the disaster countermeasure support device 1 integrates the two third disaster-affected facilities 2611 into disaster-affected facilities with the same disaster management number, and manages only one of them in terms of priority processing. In this way, the disaster countermeasure support device 1 manages multiple disaster-affected facilities that are geographically or systematically adjacent or close to each other as the same disaster-affected facility in terms of priority processing. Enable countermeasures to be taken.

Furthermore, the disaster countermeasure support device 1 changes the priority of the first disaster-affected facility 2609 to be higher than the priority of the third disaster-affected facility 2611, which has been reconfigured into the same disaster-affected facility, and changes the priority of the second disaster-affected facility 2610 to The priority is changed to be higher than that of the third disaster-affected facility 2611. In this way, the disaster countermeasure support device 1 changes the priority of the disaster-affected equipment with fewer downstream communication equipment to a higher priority for disaster-affected equipment having the same priority. By giving a higher priority to disaster-affected equipment that has a small number of affected communication equipment (or users), the user can prioritize disaster-stricken equipment that can be expected to have an immediate recovery effect through recovery work. Note that the priority order adjustment described here is just an example, and for example, the ordering described here may be reversed.

FIG. 27 is a diagram showing an example of a disaster-affected equipment management table 1100 for explaining the priority change process s70. As shown in the figure, the disaster countermeasure support device 1 refers to the equipment-line information 160, etc., and identifies the area of the disaster equipment group 2701 with the disaster management number “7” and the area of the disaster equipment group 2702 with the disaster management number “25”. It is specified from the disaster equipment management table 1100 that the areas are adjacent to each other. Then, the disaster countermeasure support device 1 integrates these disaster-affected equipment group 2701 and disaster-affected equipment 2702 to create a disaster-affected equipment management table 1100 that is reconfigured into a disaster-affected equipment group 2703 with disaster management number “7”.

Note that the priority change process s70 described above is an example, and there may be various methods for integrating disaster-affected equipment and changing the priority order.

<Priority correction processing, parameter adjustment processing>
Next, the priority correction process s80 and the parameter adjustment process s100 will be explained.

FIG. 28 is a diagram showing an example of a priority correction screen 2800 displayed in priority correction processing s80. The priority correction screen 2800 displays the total priority 2801 calculated using all the degrees of urgency and impact for each disaster-affected facility, and only the degree of urgency or impact entered on the priority calculation formula editing screens 1400 and 1500. This is a screen showing the relationship with the specified priority 2802 calculated using the scatter diagram 2803. The user can move the position of the disaster equipment 2804 on the scatter diagram 2803 (reference numeral 2805). Thereby, the disaster countermeasure support device 1 stores the changed priority of the disaster-affected facility 2804.

Then, in the parameter adjustment process s100, the disaster countermeasure support device 1 changes the parameter or its weight value related to the degree of urgency or influence, which is the basis for calculating the priority, in accordance with the changed priority.

For example, the disaster countermeasure support device 1 may search for parameter values or weight values in the degree of urgency or degree of impact that will yield the changed priority. For example, the disaster countermeasure support device 1 applies the newly changed priorities to a learned model that has been subjected to machine learning using the priority change history (the user's modification history on the priority modification screen 2800) as learning data. By inputting it, a changed value of the parameter or weight value may be calculated. Further, the disaster countermeasure support device 1 may display a screen prompting to change the calculation formula for the degree of urgency or degree of impact.

FIG. 29 is a diagram illustrating an example of a priority correction screen 2900 when a specified priority based on the current number of affected units 2101 (first degree of influence) is specified as the specified priority. As shown in the figure, in the scatter diagram 2903 of this priority correction screen 2900, the designated priorities of disaster management numbers "3" and "5" are the same, but all priorities of disaster management number "3" are This is much higher than the overall priority of management number "5". Therefore, the user or the disaster countermeasure support device 1 may use the priority modification screen 2900 to change the weight values related to parameters other than the first degree of influence. Alternatively, by referring to the entire scatter diagram 2903, the user can also determine that the disaster management number "3" may be an outlier due to some factor other than the current number of affected households.
Further, the overall priority level is extremely low compared to the designated priority level of the disaster-affected facility with the disaster management number "6". Therefore, the user or the disaster countermeasure support device 1 may use the priority modification screen 2900 to change the weight value related to the first degree of influence (here, the current number of affected units 2101).

FIG. 30 is a diagram showing an example of a priority correction screen 3000 when a priority based on the degree of secondary disaster occurrence 1602 (first degree of urgency) is specified as the specified priority. As shown in the figure, in this scatter diagram 3003, the overall priority of the disaster-affected equipment with the disaster management number "2" related to the related keyword "slope" is extremely high. Therefore, it is conceivable that the user or the disaster countermeasure support device 1 lowers the weight value (secondary disaster occurrence rate 1602 here) related to the related keyword "slope". Furthermore, even though the disaster-affected facilities with disaster management number ``1'' have a low possibility of secondary damage occurring and will not have a large number of affected households in the future, their total priority is high. Therefore, the user or the disaster countermeasure support device 1 may change parameters other than the secondary disaster occurrence rate 1602 and the future number of affected households 2012 and the corresponding weight values.

As described above, through the parameter adjustment process s100, if the user experiences a feeling of discomfort with the priority calculated by the disaster countermeasure support device 1 using a predetermined algorithm, the user can change the priority based on his own knowledge. You can make fine adjustments. This allows the user to take more practical measures against disasters.

As explained above, the disaster countermeasure support device 1 of the present embodiment estimates the disaster area based on the location information of the user in the communication failure information that is the report information, identifies the disaster-affected equipment based on the disaster-stricken area, and Based on the equipment and disaster information (damaged equipment information and disaster information), calculate the degree of urgency and impact of the damaged equipment, calculate the priority for the damaged equipment based on the degree of urgency, impact, and reliability, and provide that information. Display.

In other words, the disaster countermeasure support device 1 calculates the degree of emergency and impact of a disaster based on failure information and disaster information from users collected from communication carriers, etc., and further takes into account the degree of reliability to develop countermeasures. Calculate priority.

In this way, according to the disaster countermeasure support device 1 of this embodiment, it is possible to effectively utilize the collected information to support planning of countermeasures against disasters.

Further, after calculating the provisional priority, the disaster countermeasure support device 1 of this embodiment accepts a modification of the disaster information from the user, and recalculates the priority based on the modified disaster information.

As a result, for example, the user can conduct a field survey of the disaster area and disaster-affected equipment based on the provisional priorities, and the disaster countermeasure support device 1 can calculate more accurate priorities based on the results of the field survey. .

In addition, the disaster countermeasure support device 1 of the present embodiment can determine the degree of emergency of the disaster-stricken equipment using the damage status of the disaster-stricken equipment, the elapsed time since the occurrence of the disaster, a detour route using communication equipment other than the disaster-stricken equipment, a deadline for the disaster-stricken equipment, or , calculated based on the magnitude of the impact on other communication equipment linked to the disaster-affected equipment.

Thereby, the disaster countermeasure support device 1 can calculate the degree of urgency in accordance with the disaster situation and operation situation.

Further, the disaster countermeasure support device 1 of the present embodiment calculates the degree of influence of disaster-affected equipment based on the number of affected households based on the disaster-affected equipment or the presence or absence of other carriers collaborating with the communication carrier.

Thereby, the disaster countermeasure support device 1 can calculate the degree of urgency according to the configuration of the communication system and other systems.

In addition, the disaster countermeasure support device 1 of the present embodiment accepts a selection of a method for calculating the degree of urgency and degree of impact from a plurality of methods for calculating the degree of urgency and degree of influence from the user, and calculates the degree of urgency and degree of influence based on the selected calculation method. Calculate the impact.

Thereby, the disaster countermeasure support device 1 can calculate the degree of urgency and the degree of impact based on the situation of the disaster and the situation of operation.

Furthermore, the disaster countermeasure support device 1 of the present embodiment estimates future disaster-affected equipment based on the disaster information and equipment-line information 160, and calculates the degree of future impact based on the estimated disaster-stricken equipment.

This makes it possible to calculate priorities that take into account disasters or secondary disasters that are likely to occur in the future, depending on the status of the communication system.

Further, the disaster countermeasure support device 1 of the present embodiment receives input from the user to modify the calculated priority.

Thereby, if the user determines empirically that the calculated priority is incorrect, the user can appropriately modify the priority and take practical disaster countermeasures.

Furthermore, the disaster countermeasure support device 1 of this embodiment changes the weight value related to the degree of urgency or degree of influence according to the corrected priority.

This allows the disaster countermeasure support device 1 to calculate more practical priorities.

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

This allows the user to take recovery measures by assigning a clear priority to each disaster-affected facility.

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

For example, some of the functional units of the information processing device in this embodiment may be replaced by other functional units. Alternatively, a plurality of functional units may be integrated into one functional unit.

Further, the calculation formulas for the degree of urgency and the degree of influence described in this embodiment are examples, and various types of calculation formulas are possible.

Further, in this embodiment, a case has been described in which a communication infrastructure is damaged, but the present invention is similarly applicable to infrastructure other than communication.
