Problems to be Solved by the Invention

[0005] Conventionally, when a large number of events such as simultaneous stops or failures occur over a wide area due to a disaster such as an earthquake, the selection of workers who perform recovery work and the order of dispatch of workers to recovery targets are determined in accordance with the recovery priorities predetermined for each recovery target. However, since the recovery priorities of each recovery target are considered to change according to the damaged state of the recovery target and / or the time zone in which the disaster occurred, it may not always be appropriate to use only the predetermined recovery priorities.

MODE FOR CARRYING OUT THE INVENTION

[0014] 〔Embodiment 1〕 <Overview of the Recovery Priority Calculation System 100> Hereinafter, an embodiment of the present invention will be described. The recovery priority calculation system 100 according to an embodiment of the present invention is a system that calculates the recovery priority of each of a plurality of recovery targets R with different locations where an event requiring a recovery operation has occurred. The recovery priority calculation system 100 acquires a default value of the recovery priority determined in advance for each recovery target R, and acquires a variation value of the recovery priority determined in advance in association with the situation that the recovery target can take for each recovery target R. The recovery priority calculation system 100 calculates the recovery priority from the acquired default value and variation value for each recovery target R.

[0015] The recovery target R is a facility in which an event requiring a recovery operation has occurred among the facilities that are the targets of the recovery priority calculation by the recovery priority calculation system 100. As an example, the recovery target R is a lifting facility, and the event is a stop of the lifting facility or the like. When the lifting facility stops due to the occurrence of a disaster such as an earthquake, the recovery priority calculation system 100 sets the stopped lifting facility as the recovery target R and calculates the recovery priority of the recovery target R.

[0016] The recovery priority is the priority of the recovery operation for the recovery target R, and can be used to specify which of the plurality of recovery targets R should be recovered preferentially. In the recovery priority calculation system 100, the recovery priority is calculated as a numerical value indicating the priority of the recovery operation for the recovery target R. Note that the recovery priority may be represented by a character or the like corresponding to the numerical value indicating the priority. Hereinafter, the numerical value indicating the recovery priority will be simply referred to as the "recovery priority" for explanation.

[0017] <Details of the recovery priority calculation system 100> Hereinafter, the details of the restoration priority calculation system 100 will be described with reference to FIG. 1. FIG. 1 is a block diagram showing the configuration of the restoration priority calculation system 100 according to Embodiment 1. As shown in FIG. 1, the restoration priority calculation system 100 includes a calculation device 1. The calculation device 1 is a device that calculates the restoration priority according to the status of the facility to be restored, which is R. Also, as shown in FIG. 1, the restoration priority calculation system 100 may include an input device 2, which is an external device for inputting information indicating the status of the facility to the calculation device 1.

[0018] <Calculation device 1> As shown in FIG. 1, the calculation device 1 includes a control unit 11, a storage unit 12, an input / output interface 13, and an output unit 14. When the calculation device 1 receives an input instructing it to calculate the restoration priority, it calculates the restoration priority according to the status of the facility to be restored, which is R. The calculation device 1 may set the facility as the restoration target R and calculate the restoration priority of the restoration target R each time the necessity of restoring the facility or the information indicating the status of the facility is updated.

[0019] Note that the information indicating the status of the facility may be stored in an external device such as the input device 2. In this case, when the calculation device 1 receives an input instructing it to calculate the restoration priority, it may acquire the information indicating the status of the facility to be restored, which is R, from the input device 2. Also, the calculation device 1 may calculate the restoration priority at predetermined time intervals.

[0020] The control unit 11 executes various processes performed in the calculation device 1. The storage unit 12 stores the information used in the calculation device 1. The input / output interface 13 is a communication module for exchanging information between the calculation device 1 and devices other than the calculation device 1. The output unit 14 outputs the restoration priority calculated in the calculation device 1. The output unit 14 may be a communication module for transmitting the information indicating the calculated restoration priority to an external device such as a device for determining the restoration path. Also, the output unit 14 may be a device such as a display for displaying the information indicating the calculated restoration priority.

[0021] (Memory unit 12) As shown in FIG. 1, the memory unit 12 stores restoration necessity information 121, default value information 122, coefficient information 123, situation information 124, and variation value information 125.

[0022] FIG. 2 is a diagram showing examples of the restoration necessity information 121, default value information 122, and coefficient information 123. As shown in FIG. 2, the restoration necessity information 121, default value information 122, and coefficient information 123 for each piece of equipment are stored in association with the identification information indicating each piece of equipment.

[0023] The restoration necessity information 121 is information indicating whether restoration work is required for each of a plurality of pieces of equipment, that is, whether each of the plurality of pieces of equipment is a restoration target R that requires restoration work. When the restoration necessity information 121 of a certain piece of equipment indicates that restoration work is required (shown as "required" in FIG. 2), the said piece of equipment is a restoration target R and becomes an object for calculating the restoration priority. When the restoration necessity information 121 of a certain piece of equipment indicates that restoration work is not required (shown as "no" in FIG. 2), the said piece of equipment is not a restoration target R and the restoration priority is not calculated.

[0024] The default value information 122 is information indicating a value that serves as a reference for the restoration priority of the restoration target R. The default value is a fixed value set in advance based on the function, installation location, and characteristics of the restoration target R. In the memory unit 12, for the sake of simplifying the setting, discrimination values such as S, A, B... may be set as the default value information 122. In this case, when calculating the restoration priority, each discrimination value is sequentially converted into a numerical value representing the default value, such as 90, 70, 50..., and then used.

[0025] The coefficient information 123 is information indicating a coefficient set according to the degree to which the variable value is reflected in the restoration priority. The coefficient is a fixed value determined for each restoration target R and is set in advance for each facility. As an example, the value of the coefficient corresponding to a normal restoration target R may be about 0.5. Also, the coefficient corresponding to a facility provided at a site where it is not desired to vary the restoration priority (for example, a site such as an emergency ward where immediate action must always be taken) may be set to a small value, for example, about 0.01. Further, the coefficient corresponding to a facility provided at a site where the restoration priority varies greatly depending on the situation such as the time zone may be set to a large value, for example, about 0.8.

[0026] Also, in the storage unit 12, the coefficient information 123 may be stored as a discrimination value representing a coefficient in order to simplify the set value, similar to the default value information 122, and may be converted into a numerical value when used for calculating the restoration priority.

[0027] The situation information 124 is information indicating the situation of the restoration target R and is used to specify the variable value of the restoration target R. The situation is the situation of the restoration target R at the time when an event occurs or the situation of the restoration target R at the time when the restoration priority is calculated. For example, the situation may be a situation where the assistance of a user is required. Specifically, as the situation information 124, information indicating whether or not there is a confinement in the restoration target R may be stored.

[0028] Also, the situation may be a time zone characteristic. The time zone characteristic is a characteristic indicating the state of the restoration target R in that time zone. Specifically, the time zone characteristic may be information indicating the number of users using the restoration target R in the time zone including the time point when an event occurs or the time point when the restoration priority is calculated. For example, the time zone characteristic may be information indicating whether it is a time zone with many users, a time zone with somewhat many users, a time zone with an average number of users, a time zone with somewhat few users, a time zone with few users, or a time zone with almost no users.

[0029] Further, the situation may be a situation indicating the necessity of giving priority to the recovery target R. Specifically, as the situation information 124, information indicating that priority response to the recovery target R is necessary, information indicating that priority response to the recovery target R is unnecessary, or information indicating that no contact has been received regarding priority response to the recovery target R may be stored.

[0030] The variable value information 125 is information indicating a variable value specified based on the situation of the recovery target R, and is set for each recovery target R. FIG. 3 shows an example of the variable value information 125 of a certain recovery target R. As shown in FIG. 3, as the variable value information 125, a situation that can occur in the recovery target R and a variable value corresponding to the situation are associated. Note that in the variable value information 125, the variable value corresponding to a situation where it is not necessary to change the recovery priority is set to 0.

[0031] For example, the situation is a situation where the rescue of the user is required in the recovery target R, and the variable value associated with the situation is determined such that the recovery priority calculated by the calculation unit 115 for the recovery target R in which the situation has occurred becomes the highest priority. Specifically, as shown in FIG. 3, the situation is the presence or absence of entrapment. When entrapment has occurred in a certain recovery target R, the variable value is set such that the recovery priority calculated regardless of the default value, coefficient, and other variable values becomes the highest. On the other hand, when entrapment has not occurred in a certain recovery target R, the variable value is set to 0.

[0032] The above situation is a situation that raises the recovery priority of the recovery target R, and the variable value associated with the situation is determined such that the recovery priority calculated by the calculation unit 115 for the recovery target R in which the situation has occurred becomes relatively high. For example, the variable value associated with the situation that raises the recovery priority is a positive value.

[0033] The above situation is a situation where the recovery priority of the recovery target R is lowered, and the variation value associated with the situation is determined so that the recovery priority calculated by the calculation unit 115 for the recovery target R in which the situation has occurred is relatively low. For example, the variation value associated with a situation where the recovery priority is increased is a negative value.

[0034] As an example, as shown in FIG. 3, the situation is a time zone characteristic, and as the variation value information 125, the situation represented by the time zone characteristic and the variation value corresponding to the situation may be associated. The time zone characteristic may be, for example, a characteristic indicating whether the number of people using the facility is more than the average.

[0035] For example, when a facility such as an elevator stops during a time zone when there are more people than the average, it is considered necessary to give priority to recovery. Therefore, the variation value associated with the situation of being in a time zone when there are more people than the average is determined so that the recovery priority is relatively high. Specifically, the variation value associated with a time zone when there are more people than the average is a positive value. Also, different variation values may be set for each level of the degree of the number of people. For example, for a time zone when there are more people than the average and a time zone when there are slightly more people than the average, the variation value associated with the time zone when there are more people than the average may be set to be larger.

[0036] Also, when an event occurs during a time zone when the number of people using the facility is about the average, there is no need to vary the recovery priority based on the time zone. Therefore, the variation value associated with a time zone when the number of people using the facility is about the average may be 0.

[0037] Also, when facilities such as elevators stop during a time period with few people, it is considered that there is little need for prioritized restoration. Therefore, the variation value associated with the situation of a time period with fewer people than the average is determined such that the restoration priority is relatively low. Specifically, the variation value associated with the situation of a time period with fewer people than the average is a negative value. Also, different variation values may be set for each level of the degree of few people. For example, for a time period with slightly fewer people than the average and a time period with fewer people than the average, the variation value associated with the time period with fewer people than the average may be set to be smaller. Also, a smaller value may be set for the variation value associated with a time period when there are almost no people and the facilities are hardly used.

[0038] As shown in FIG. 3, the situation is, for example, whether or not prioritized response is necessary, and as the variation value information 125, a situation indicating whether or not prioritized response is necessary and a variation value corresponding to the situation may be associated. The situation indicating whether or not prioritized response is necessary may be, for example, any one of whether a notice indicating that prioritized response is necessary has been received, whether a notice indicating that prioritized response is unnecessary has been received, or whether no notice regarding prioritized response has been received.

[0039] For example, for a certain restoration target R, when a notice indicating that it is necessary to prioritize restoration has been received, it is considered that there is a high need to prioritize the restoration of the restoration target R. Therefore, the variation value associated with the situation of receiving a notice indicating that prioritized response is necessary is a positive value. On the other hand, for a certain restoration target R, when a notice indicating that there is no need to prioritize restoration has been received, it is considered that there is a low need to prioritize the restoration of the restoration target R. Therefore, the variation value associated with the situation of receiving a notice indicating that prioritized response is unnecessary is a negative value. Also, for a certain restoration target R, when no notice regarding the need to prioritize restoration has been received, there is no need to change the restoration priority based on the necessity of prioritized response. Therefore, the variation value associated with the situation of not receiving a notice regarding prioritized response is 0.

[0040] (Control Unit 11) As shown in FIG. 1, the control unit 11 includes an update unit 111, a specifying unit 112, a default value acquisition unit 113, a variable value acquisition unit 114, a calculation unit 115, and an output control unit 116.

[0041] (Update Unit 111) The update unit 111 updates the storage unit 12. For example, when the update unit 111 acquires information indicating that an event requiring a recovery operation has occurred for a certain facility or information indicating that the recovery operation has been completed, the update unit 111 updates the recovery necessity information 121 based on the information. In addition, each time the update unit 111 acquires the situation information 124, the update unit 111 updates the situation information 124 in the storage unit 12. The update unit 111 may acquire information by receiving it from an input device 2 outside the calculation device 1 via the input / output interface 13, or may acquire information by inputting it to an input unit (not shown) provided in the calculation device 1. When the update unit 111 updates the storage unit 12, the update unit 111 may output information indicating that the update has been performed to the specifying unit 112.

[0042] (Specifying Unit 112) The specifying unit 112 specifies a recovery target R for which the recovery priority is to be calculated. The specifying unit 112 refers to the storage unit 12 and specifies equipment that requires a recovery operation (equipment for which the recovery necessity is "required" in FIG. 2) among the equipment stored in the storage unit 12. The specifying unit 112 specifies the equipment that requires a recovery operation as the recovery target R and outputs information indicating the specified recovery target R to other processing units of the control unit 11. Thereby, in the calculation device 1, the calculation of the recovery priority of the recovery target R is started.

[0043] Note that the specifying unit 112 may confirm the recovery necessity of all the equipment stored in the storage unit 12, or may confirm only the recovery necessity of the equipment existing in the specified area among the equipment stored in the storage unit 12.

[0044] In addition, the specifying unit 112 may specify the recovery target R when an event occurs and the storage unit 12 is updated. Further, the specifying unit 112 may specify the recovery target R at predetermined time intervals after an event occurs. Further, the specifying unit 112 may specify the recovery target R each time the status information 124 of the recovery target R is updated by the updating unit 111. Further, the specifying unit 112 may specify the recovery target R when receiving an instruction to start a process of calculating a recovery priority via an external input device 2 or an input unit (not shown) of the calculation device 1.

[0045] (Default value acquisition unit 113) The default value acquisition unit 113 acquires a default value of the recovery priority, which is predetermined for each recovery target R. Specifically, when the default value acquisition unit 113 acquires information indicating the recovery target R from the specifying unit 112, it refers to the storage unit 12 and acquires the default value of the recovery priority corresponding to the recovery target R. The default value acquisition unit 113 also acquires a coefficient determined for the recovery target R. The default value acquisition unit 113 outputs the acquired default value and coefficient to the calculation unit 115. When there are a plurality of recovery targets R, the default value acquisition unit 113 acquires the default values and coefficients of each of the plurality of recovery targets R.

[0046] (Variable value acquisition unit 114) The variable value acquisition unit 114 acquires a variable value of the recovery priority, which is predetermined in association with each possible status of the recovery target R, for each recovery target R. The variable value acquisition unit 114 outputs the acquired variable value to the calculation unit 115.

[0047] Specifically, when the variable value acquisition unit 114 acquires information indicating the recovery target R, it refers to the storage unit 12, acquires the status information 124 of the recovery target R, and specifies the status of the recovery target R. When the status information 124 includes items indicating a plurality of statuses, the variable value acquisition unit 114 specifies the status corresponding to each of the plurality of items. For example, the variable value acquisition unit 114 specifies whether or not confinement has occurred in the recovery target R, time zone characteristics, necessity of priority correspondence communication, and other statuses.

[0048] Note that the time zone characteristic may be the characteristic in the time zone when an event occurs in the recovery target R, or may be the characteristic in the time zone when the calculation of the recovery priority is performed. Also, the communication regarding the necessity of priority correspondence is information indicating the presence or absence of a communication indicating that it is necessary to recover preferentially and the presence or absence of a communication indicating that it is not necessary to recover preferentially.

[0049] When the variation value acquisition unit 114 identifies the situation of the recovery target R, it refers to the variation value information 125 and acquires the variation value of the recovery priority determined in advance in association with the situation that the recovery target R can take based on the situation of the recovery target R.

[0050] As an example, in the recovery target R in which the correspondence between the situation shown in FIG. 3 and the variation value is set, when there is no confinement, the time zone characteristic is a time zone in which the number of users is slightly more than the average, there is no communication regarding priority correspondence, and there is no information regarding other situations, it will be described. In this case, the variation value acquisition unit 114 acquires 0, 40, 0, and 0 as the variation values corresponding to the respective situations.

[0051] Note that when there are a plurality of recovery targets R, the variation value acquisition unit 114 acquires the variation value of each of the plurality of recovery targets R.

[0052] (Calculation unit 115) The calculation unit 115 calculates the recovery priority for each recovery target R from the default value and the variation value. When the calculation unit 115 acquires the default value, the coefficient, and the variation value from the default value acquisition unit 113 and the variation value acquisition unit 114, it calculates the recovery priority of the recovery target R from the multiplication value based on the default value and the variation value.

[0053] The calculation unit 115 calculates the recovery priority by adding the default value and the multiplication value obtained by multiplying the coefficient determined for each recovery target R by the variation value. Specifically, the calculation unit 115 calculates the recovery priority using the following formula (1). Note that when there are a plurality of variation values, the calculation unit 115 uses the sum of the plurality of variation values as the variation value. Recovery priority = Default value + {(Coefficient) × (Variation value)} ··· Formula (1)

[0054] Here, the variation value used for calculating the recovery priority is set according to the situation of the recovery target R. For example, a positive value is set as the variation value corresponding to a situation where the recovery priority of the recovery target R is increased, such as when the user is in a time period slightly longer than the average. If the user is in a more frequent time period, a value larger than the variation value when it is a slightly longer time period is set. On the other hand, for example, a negative value is set as the variation value corresponding to a situation where the recovery priority of the recovery target R is decreased, such as when the user is in a time period slightly shorter than the average. If the user is in a less frequent time period, a value smaller than the variation value when it is a slightly shorter time period is set. Therefore, the calculation unit 115 can calculate the recovery priority according to the situation of the recovery target R.

[0055] Also, a large value coefficient is set for the recovery target R for which the priority may be changed according to the situation, and a small value coefficient is set for the recovery target R for which the priority should not be greatly changed regardless of the situation. Thereby, for the recovery target R for which the priority may be changed, the variation value has a great influence on the recovery priority, and for the recovery target R for which the priority should not be greatly changed, the variation value has little influence on the recovery priority. Therefore, the calculation unit 115 can calculate a more appropriate recovery priority for each recovery target R.

[0056] When there are a plurality of recovery targets R, the variation value acquisition unit 114 calculates the recovery priority of each of the plurality of recovery targets R.

[0057] Note that the calculation unit 115 may calculate the recovery priority without using a coefficient. In this case, the calculation unit 115 may use the value obtained by adding the variation value to the default value as the value indicating the recovery priority.

[0058] In addition, when there are multiple recovery targets R at one site, the calculation unit 115 may use a part of the multiple recovery targets R existing at one site as a representative value of the recovery priority of the recovery targets R at that site. Specifically, when a plurality of elevators provided in one building are stopped, the calculation unit 115 calculates the recovery priority for each of the plurality of elevators that are the recovery targets R, and may use the highest value as the representative value of the recovery priority of the recovery targets R provided at that site.

[0059] (Output control unit 116) The output control unit 116 acquires the recovery priority calculated by the calculation unit 115 and outputs it to the output unit 14. When the calculation unit 115 calculates the recovery priorities of a plurality of recovery targets R, the output control unit 116 outputs information indicating the recovery priorities of all the calculated recovery targets R to the output unit 14.

[0060] For example, when the output unit 14 is a communication module for communicating with an external device and the calculation device 1 is communicably connected to a device that determines the route and work order of the recovery work, etc., the output control unit 116 may transmit information associating the recovery target R with the recovery priority to the device via the output unit 14. Further, the output control unit 116 may transmit the information to other devices.

[0061] In addition, when the output unit 14 is a device such as a display, the output control unit 116 may control the output unit 14 to display information indicating the recovery priority and information indicating the position of the recovery target R on the map.

[0062] <Specific example of recovery priority calculation> Hereinafter, a specific example of the correspondence between the situation of the recovery target R and the recovery priority calculated by the calculation unit 115 in the calculation device 1 will be described.

[0063] First, in FIG. 2, a case where an event occurs in the facility indicated by the identification information "001" (hereinafter referred to as facility 001) and the facility becomes a recovery target R will be described. Here, facility 001 is a facility without any special circumstances that need to be considered in advance regarding the recovery priority, and the default value and coefficient are set to average values. Specifically, as shown in FIG. 2, the default value of facility 001 is set to 50, and the coefficient is set to 0.5.

[0064] When an event occurs in facility 001 and facility 001 becomes a recovery target R, and there is no occurrence of confinement, the variation value corresponding to this situation is 0. Also, when an event occurs during a time period when the number of users is average, the variation value corresponding to this time period is 0. Further, when there is no situation that needs to be considered regarding the increase or decrease of the variation value in other aspects, the variation value corresponding to other situations is 0. Therefore, the formula (2) obtained by substituting each value into the above formula (1) to calculate the recovery priority of facility 001 is as follows. Recovery priority of facility 001 = 50 + {0.5 × (0 + 0 + 0)} ··· Formula (2)

[0065] The recovery priority of facility 001 calculated by the calculation unit 115 based on formula (2) is 50. Thus, when there are no special circumstances with respect to the recovery target R itself and no situation that needs to be considered occurs, the recovery priority calculated for the recovery target R is a recovery priority similar to the default value.

[0066] Next, in FIG. 2, a case where an event occurs in the facility indicated by the identification information "002" (hereinafter referred to as facility 002) and the facility becomes a recovery target R will be described. Here, facility 002 is a facility with a preset high recovery priority. However, facility 002 is a facility where the number of users varies greatly depending on the time period. Therefore, the default value and coefficient of facility 002 are set to relatively high values. Specifically, as shown in FIG. 2, the default value of facility 002 is set to 70, and the coefficient is set to 0.8.

[0067] When an event occurs in equipment 002 and the equipment 002 becomes a recovery target R, and in a situation where no confinement has occurred, the variation value corresponding to this situation is 0. Also, when an event occurs during a time period when there are almost no users, the variation value corresponding to this time period is -80. Further, when there is no situation that needs to be considered regarding the increase or decrease of the variation value, the variation value corresponding to other situations is 0. Therefore, the formula (3) obtained by substituting each value into the above formula (1) to calculate the recovery priority of equipment 002 is as follows. Recovery priority of equipment 002 = 70 + [0.8 × {0 + (-80) + 0}] ··· Formula (3)

[0068] Based on the above formula (3), the recovery priority of equipment 002 calculated by the calculation unit 115 is 6. Thus, even for a recovery target R with a preset high default value of the recovery priority, when it is a situation where the recovery priority of the recovery target R may be decreased, the recovery priority is calculated considering this situation. Also, for a recovery target R for which the recovery priority may be increased or decreased depending on the situation, by setting a high coefficient, the influence of the variation value according to the situation on the recovery priority can be increased. Specifically, like equipment 002, for a recovery target R where there is no problem even if the recovery is delayed when an event occurs during a time period with few users, a relatively low recovery priority is calculated. Also, in equipment 002, since the coefficient is set high, the influence of the variation value by the time period on the recovery priority can be increased. Thereby, the recovery priority of the recovery target R that should be recovered preferentially over other equipment 002 can be made relatively high.

[0069] Next, in Fig. 2, a case will be described where an event occurs in the facility indicated by the identification information "003" (hereinafter referred to as facility 003), and the facility becomes a recovery target R. Here, facility 003 is a facility with a relatively high preset recovery priority. Therefore, a relatively high value is set as the default value of facility 003. Also, facility 003 is a facility such as an emergency ward, and although the number of users varies depending on the time zone, it is a facility that should be recovered by sending maintenance personnel immediately if an event occurs regardless of the time zone. Therefore, a relatively low value is set as the coefficient of facility 003. Specifically, as shown in Fig. 2, the default value of facility 003 is set to 90 and the coefficient is set to 0.01.

[0070] When an event occurs in facility 003 and facility 003 becomes a recovery target R, and there is no occurrence of confinement, the variation value corresponding to this situation is 0. Also, when an event occurs during a time zone with almost no users, the variation value corresponding to this time zone is -50. Also, when there is no situation that needs to be considered regarding the increase or decrease of the variation value in other cases, the variation value corresponding to other situations is 0. Therefore, the formula (4) obtained by substituting each value into the above formula (1) to calculate the recovery priority of facility 003 is as follows. Recovery priority of facility 003 = 90 + (0.01 × (0 + (-50) + 0)) ··· Formula (4)

[0071] The recovery priority of facility 003 calculated by the calculation unit 115 based on the above formula (4) is 89.5. Thus, for the recovery target R that should be preferentially recovered regardless of the situation when an event occurs, a relatively high recovery priority can be calculated. Specifically, by setting a high default value and a low coefficient like facility 003, for the recovery target R that should be recovered quickly even if an event occurs during a time zone with few users, a relatively high recovery priority is calculated.

[0072] Next, in FIG. 2, a case will be described where an event occurs in the facility indicated by the identification information "004" (hereinafter referred to as facility 004), and the facility becomes a recovery target R. Here, facility 004 is a facility with a preset low recovery priority. Therefore, the default value and coefficient of facility 004 are set to low values. Also, facility 004 is a facility without any special circumstances that need to be considered in advance regarding the recovery priority. Therefore, the coefficient of facility 004 is set to an average value. Specifically, as shown in FIG. 2, the default value of facility 004 is set to 30, and the coefficient is set to 0.5.

[0073] Here, when an event occurs in the facility and the facility becomes a recovery target R, if confinement occurs, the variation value corresponding to the situation of the occurrence of confinement is set so that the recovery priority is maximized regardless of the default value, coefficient, and variation value. Specifically, the variation value when confinement occurs in facility 004 is 1000000. Also, when an event occurs during a time period when the number of users is less than the average, the variation value corresponding to that time period is -40. Also, when there are no other situations that need to be considered regarding the increase or decrease of the variation value, the variation value corresponding to other situations is 0. Therefore, the formula (5) obtained by substituting each value into the above formula (1) to calculate the recovery priority of facility 004 is as follows. Recovery priority of facility 004 = 30 + (0.5 × (1000000 + (-40) + 0)) ··· Formula (5)

[0074] Based on the above formula (5), the recovery priority of facility 004 calculated by the calculation unit 115 is 500010. Note that since any value exceeding 100 in the calculated recovery priority is truncated, the final recovery priority is 100.

[0075] Thus, even for a recovery target R with a low default value of the preset recovery priority, when a situation occurs where the recovery priority of the recovery target R should be increased, the recovery priority is calculated in consideration of this situation. In particular, when a situation where there are people in need of rescue occurs, such as when a confinement occurs, the calculation unit 115 calculates the highest recovery priority regardless of the default value, the coefficient, and the variation value based on other situations. Therefore, for the recovery target R for which recovery should be prioritized, the highest recovery priority can be calculated regardless of the preset recovery priority and other situations of the recovery target R.

[0076] Next, in FIG. 2, a case where no event has occurred in the facility indicated by the identification information "005" (hereinafter referred to as facility 005) will be described. In this case, the calculation unit 115 does not calculate the recovery priority of the facility 005. Thereby, in the consideration of the recovery work of the recovery target R, the possibility that the facility 005 that does not require the recovery work becomes noise can be reduced.

[0077] Hereinafter, with reference to FIGS. 4 and 5, the comparison results between the preset recovery priorities of the respective facilities and the recovery priorities when events have actually occurred in a plurality of facilities will be described. FIG. 4 shows the positions of the facilities on the map and the recovery priorities based on the default values of the respective facilities. Further, FIG. 5 shows the positions of the facilities on the map and the recovery priorities based on the default values, coefficients, and variation values of the respective facilities.

[0078] In FIGS. 4 and 5, the black circles indicate high recovery priority. Specifically, the black circles indicate that the recovery priority is 70 or more. Also, in FIGS. 4 and 5, the circled dots indicate medium recovery priority. Specifically, the circled dots indicate that the recovery priority is 0 or more and less than 70. Also, in FIGS. 4 and 5, the hatched circles indicate low recovery priority. Specifically, the hatched circles indicate that the recovery priority is -100 or more and less than 0. Also, in FIGS. 4 and 5, the white circles indicate that the recovery priority is not calculated.

[0079] In FIGS. 4 and 5, the circles indicated by reference numerals 401 and 501 represent facility 001. The circles indicated by reference numerals 402 and 502 in FIGS. 4 and 5 represent facility 002. The circles indicated by reference numerals 403 and 503 in FIGS. 4 and 5 represent facility 003. The circles indicated by reference numerals 404 and 504 in FIGS. 4 and 5 represent facility 004. The circles indicated by reference numerals 405 and 505 in FIGS. 4 and 5 represent facility 005.

[0080] When a disaster such as an earthquake occurs in the areas shown in FIGS. 4 and 5, the recovery priority calculation system 100 calculates the recovery priority of the recovery target R within the area. Here, as shown in FIGS. 4 and 5, according to the recovery priority calculation system 100, it is possible to change the actual recovery priority from the preset recovery priority according to the status of the facility.

[0081] Specifically, as shown by reference numerals 401 and 501, when facility 001 becomes the recovery target R, since there are no particular circumstances to be considered, the actual recovery priority is the same medium level as the preset recovery priority. Also, as shown by reference numerals 402 and 502, it can be seen that for facility 002 where an event occurred at a time when there were few users, although the preset recovery priority is high, the actual recovery priority is medium. Also, as shown by reference numerals 403 and 503, when facility 003, which is a facility that should be recovered preferentially when an event occurs regardless of the situation, becomes the recovery target R, the actual recovery priority becomes as high as the preset recovery priority. Also, as shown by reference numerals 404 and 504, it can be seen that for facility 004 where entrapment occurred, although the preset recovery priority is low, the actual recovery priority is high.

[0082] Also, for facility 005 where no event occurred, the recovery priority is not calculated in the recovery priority calculation system 100. Therefore, by using the calculation result of the recovery priority by the recovery priority calculation system 100, it is possible to determine the priority and route of the actual recovery work, etc., with reference to the recovery priority according to the actual situation of the recovery target R that requires recovery.

[0083] <An example of the processing flow of the restoration priority calculation system 100> Hereinafter, an example of the processing performed in the restoration priority calculation system 100 will be described with reference to FIG. 6. FIG. 6 is a flowchart for explaining an example of the processing performed in the restoration priority calculation system 100. The processing shown in FIG. 6 is performed when an event that requires a restoration operation for the facility occurs, such as when the facility stops due to an earthquake, and the facility becomes the restoration target R.

[0084] When an event occurs, the calculation device 1 starts the processing by receiving an instruction from the person who makes the plan for the restoration operation via the input device 2 or the input unit (not shown) of the calculation device 1. Note that the calculation device 1 may perform the processing shown in FIG. 6 at predetermined time intervals, for example, every 30 minutes after the occurrence of the event. Further, the calculation device 1 may perform the processing shown in FIG. 6 each time the update unit 111 receives information regarding the restoration target R, for example, information indicating that an event has occurred in the facility and restoration is required, or information indicating the state of the restoration target R, and updates the storage unit 12.

[0085] First, the specifying unit 112 specifies the restoration target R among the facilities for which an event has occurred and for which a restoration operation is required (S1). Specifically, the specifying unit 112 specifies, as the restoration target R, the facility in which the restoration necessity information 121 indicates the need for restoration in the storage unit 12. The specifying unit 112 outputs information indicating the specified restoration target R to each part of the control unit 11. Note that the specifying unit 112 may specify only the facility for which restoration has newly become necessary or the facility in which the situation information 124 has been updated as the restoration target R. Thereby, in the calculation device 1, it is possible to reduce the effort of calculating the restoration priority of the restoration target R for which the restoration priority has already been calculated and the situation has not changed thereafter.

[0086] Next, when the default value acquisition unit 113 acquires information indicating the restoration target R, it refers to the storage unit 12 to acquire the default value of the restoration priority determined for the restoration target R (S2: default value acquisition step). Also, the default value acquisition unit 113 acquires the coefficient determined for the restoration target R (S3). The default value acquisition unit 113 outputs the acquired default value and coefficient to the calculation unit 115.

[0087] When the variable value acquisition unit 114 acquires information indicating the restoration target R, it refers to the storage unit 12 to acquire the status information 124 of the restoration target R (S4) and identifies the status of the restoration target R. Subsequently, the variable value acquisition unit 114 refers to the variable value information 125 and acquires the variable value of the restoration priority predetermined in association with the status that the restoration target R can take based on the status of the restoration target R (S5: variable value acquisition step).

[0088] When there are a plurality of items regarding the status of the restoration target R, the variable value acquisition unit 114 acquires the variable value of the restoration target R for each of the plurality of items. For example, the variable value acquisition unit 114 acquires the variable values corresponding to each of the items shown in FIG. 3, specifically, whether or not confinement has occurred in the restoration target R, the time zone characteristics of the restoration target R at the time when the restoration priority calculation is performed, the necessity of priority response, and other items. The variable value acquisition unit 114 outputs the acquired variable value to the calculation unit 115.

[0089] When the calculation unit 115 acquires the default value, coefficient, and variable value, it calculates the restoration priority of the restoration target R from the multiplication value based on the default value and the variable value (S6: calculation step). Specifically, the calculation unit 115 calculates a multiplication value obtained by multiplying the total value of the variable values by the coefficient, and calculates the value obtained by adding the multiplication value calculated to the default value as the restoration priority of the restoration target R.

[0090] As described above, in the recovery priority calculation system 100, the recovery priority corresponding to the situation of the recovery target R is calculated. When there are a plurality of recovery targets R identified by the specific unit 112, that is, when there are a plurality of recovery targets R for which the recovery priority is to be calculated, the recovery priority calculation system 100 performs the processes of steps S2 to S6 for each of the plurality of recovery targets R, and calculates the recovery priority for each recovery target R.

[0091] Further, the output control unit 116 may output, via the output unit 14, the identification information indicating the recovery target R and the information indicating the calculated recovery priority of the recovery target R in association with each other to an external device or the like. Thereby, the external device can use the recovery priority calculated by the recovery priority calculation system 100.

[0092] 〔Embodiment 2〕 Other embodiments of the present invention will be described below. For the sake of convenience of explanation, members having the same functions as the members described in the above embodiment are given the same reference numerals, and the description thereof will not be repeated.

[0093] FIG. 7 is a block diagram showing the configuration of a recovery priority calculation system 100A according to Embodiment 2. Hereinafter, the recovery priority calculation system 100A according to Embodiment 2 will be described with reference to FIG. 7. The recovery priority calculation system 100A according to Embodiment 2 calculates the recovery priority using a coefficient that varies according to the situation when calculating the recovery priority.

[0094] As shown in FIG. 7, the recovery priority calculation system 100A includes a calculation device 1A. The calculation device 1A is different from the calculation device 1 in that it includes a control unit 11A instead of the control unit 11 and a storage unit 12A instead of the storage unit 12. The control unit 11A includes a calculation unit 115A instead of the calculation unit 115. Further, the storage unit 12A stores coefficient information 123A instead of the coefficient information 123.

[0095] Coefficient information 123A is information indicating coefficients used in the recovery priority calculation system 100A. The coefficients indicated by the coefficient information 123A vary according to the situation when calculating the recovery priority.

[0096] The calculation unit 115A calculates the recovery priority using a default value, a coefficient, and a variable value. Note that the calculation unit 115A identifies the coefficient corresponding to the situation when an event occurs in the recovery target R, and uses the identified coefficient for calculating the multiplication value.

[0097] As an example, the coefficients are predetermined for each recovery target R in association with each time zone. FIG. 8 is a diagram showing an example of coefficient information 123A in which a plurality of coefficients and a plurality of time zones are respectively associated. The calculation unit 115A uses the coefficient associated with the time zone to which the time when the event occurs in the recovery target R belongs for calculating the multiplication value. Note that when calculating the recovery priority after a certain period of time has elapsed since the event occurred, the calculation unit 115A may use the coefficient associated with the time zone to which the time when the recovery priority is calculated belongs for calculating the multiplication value.

[0098] As another example, the coefficients may be determined for each recovery target R in association with each day of the week. FIG. 9 is a diagram showing an example of coefficient information 123A in which a plurality of coefficients and each day of the week are respectively associated. The calculation unit 115A uses the coefficient associated with the day of the week when the above event occurs in the recovery target R for calculating the multiplication value.

[0099] As yet another example, for each recovery target R, a coefficient for business days and a coefficient for non-business days may be predetermined. FIG. 10 is a diagram showing an example of coefficient information 123A in which a plurality of coefficients and whether the facility where the recovery target R is provided is a business day or not are respectively associated. The calculation unit 115A uses the coefficient determined according to whether the day when the event occurs in the recovery target R to be calculated for the recovery priority is a business day of the recovery target for calculating the multiplication value.

[0100] Note that in coefficient information 123A, two or more conditions among time zone, day of the week, and business day may be associated with coefficients. For example, different coefficients may be associated with each of the conditions of daytime on Sunday, nighttime on Sunday, and nighttime on Monday. The calculation unit 115A identifies a suitable coefficient based on the time when the event occurred or the time when the recovery priority is calculated, and uses it for calculating the multiplication value.

[0101] Also, in coefficient information 123A, other conditions may be further associated with coefficients. The calculation unit 115A acquires the coefficient corresponding to the condition stored in the coefficient information 123A based on the status of the recovery target R, and uses it for calculating the multiplication value.

[0102] How much the variation value should be reflected in the recovery priority in the recovery target R may vary depending on the status of the recovery target R, for example, the time when an event occurred in the recovery target R, or the time when the recovery priority of the recovery target R is calculated.

[0103] For example, if the recovery target R is a facility such as a hospital with a high default value, and an event occurs during the time when another hospital in the vicinity is operating, there are other available hospitals in addition to the hospital where the recovery target R is provided. Therefore, even if the recovery priority of the recovery target R decreases according to the variation value and the recovery is delayed, it is considered that the impact is relatively small. On the other hand, if an event occurs during the time when another hospital in the vicinity is not operating, since there are no other available hospitals in addition to the hospital where the recovery target R is provided, it is preferable to avoid a decrease in the function of the hospital where the recovery target R is provided. Therefore, when an event occurs during the time when another hospital in the vicinity is not operating, it is considered preferable to set the recovery priority of the recovery target R to a high value regardless of the variation value.

[0104] Here, in the recovery priority calculation system 100A, the coefficient varies according to the situation of the recovery target R, for example, the time when an event occurs in the recovery target, and the calculation unit 115A calculates the recovery priority using the coefficient corresponding to the situation of the recovery target R. Therefore, the recovery priority calculation system 100A can change the degree to which the variation value is reflected in the recovery priority according to the situation of the recovery target R, and calculate a more appropriate recovery priority.

[0105] 〔Embodiment 3〕 Hereinafter, the recovery priority calculation system 100B according to Embodiment 3 will be described. The recovery priority calculation system 100B calculates a variation value based on the degree of utilization indicating how much the facility is utilized in a predetermined time period, and calculates the recovery priority using the variation value obtained as a result of the calculation.

[0106] FIG. 11 is a block diagram showing the configuration of the recovery priority calculation system 100B according to Embodiment 3. As shown in FIG. 11, the recovery priority calculation system 100B is different from the recovery priority calculation system 100 in that it includes a calculation device 1B instead of the calculation device 1. Further, the calculation device 1B is different from the calculation device 1 in that it includes a control unit 11B and a storage unit 12B.

[0107] The control unit 11B includes an update unit 111, a specifying unit 112, a default value acquisition unit 113, a utilization degree information acquisition unit 117, a calculation unit 118, a calculation unit 115, and an output control unit 116. Further, in addition to the information stored in the storage unit 12, the storage unit 12B further stores utilization degree information 126.

[0108] The utilization degree information 126 is information indicating the normal utilization degree for each time period with a predetermined time length as one unit. FIGS. 12 and 13 are diagrams showing examples of the utilization degree information 126. As shown in FIGS. 12 and 13, as the utilization degree information 126, for example, with one hour as one unit, numerical values representing the utilization degree for each hour and information indicating the time period are associated with each other. Further, as shown in FIGS. 12 and 13, the numerical values representing the utilization degree may be shown in the range of -100 or more and 100 or less.

[0109] The method for setting the utilization degree information 126 will be described below. First, in the most recent 30 days of the target facility, the average number of operations per hour and the average moving distance per hour are specified on a daily basis. Then, based on the calculated average number of operations per hour and the average moving distance per hour for each of the 30 days, the utilization rate for each hour of the day is calculated. The time period with the highest calculated utilization rate is set to 100, and the time period with the lowest utilization rate is set to -100. Based on these indicators, a value representing the utilization rate for each time period is determined. The determined value is used as the numerical value representing the degree of utilization for each time period. In this way, the utilization degree information 126 for the target facility is set.

[0110] Note that when associating the utilization rate with the indicator representing the utilization rate, the utilization rates of multiple facilities may be used. For example, in two facilities, a certain facility A and another facility B, the time period with the highest utilization rate can be set to 100, and the time period with the lowest utilization rate can be set to -100, and values indicating the degree of utilization of each facility can be set accordingly.

[0111] (Utilization Degree Information Acquisition Unit 117) The utilization degree information acquisition unit 117 acquires the utilization degree information 126 indicating the normal utilization degree for each time period with a predetermined time length as one unit.

[0112] The utilization degree information acquisition unit 117 refers to the storage unit 12B and acquires the utilization degree information 126 for the first time period consisting of one or more units of time periods after the time when the event occurred. The utilization degree information acquisition unit 117 acquires, as the utilization degree information 126 for the first time period, the value indicating the utilization degree for the first time period, or the average value of the utilization degree values for the plurality of units of time periods including the said time.

[0113] The range of the first time period may be, for example, 4 hours. When the restoration priority is calculated at the timing when an event occurs, the usage degree information acquisition unit 117 sets the time period from 4 hours after the time when the event occurs as the first time period, and acquires the average value of the usage degrees of the time periods included in the first time period. Specifically, when one unit is 1 hour and the event occurs at 1:17, the usage degree information acquisition unit 117 acquires the average value of the usage degree values of the 1 o'clock period, 2 o'clock period, 3 o'clock period, and 4 o'clock period as the usage degree information 126 of the first time period.

[0114] Also, when the restoration priority is calculated after an event occurs and time has passed, the usage degree information acquisition unit 117 may set the time period from 4 hours after the time when the restoration priority is calculated as the first time period, and acquire the average value of the usage degrees of the time periods included in the first time period. For example, when the event occurs at 1:17 and the restoration priority is calculated at 3:05, the usage degree information acquisition unit 117 may acquire the average value of the usage degree values of the 3 o'clock period, 4 o'clock period, 5 o'clock period, and 6 o'clock period as the usage degree information 126 of the first time period.

[0115] Also, the usage degree information acquisition unit 117 refers to the storage unit 12B and specifies the usage degree information 126 of the second time period composed of the first time period and one or more unit time periods following the first time period. The range of the second time period includes the first time period and may be a time longer than the first time period, for example, 12 hours. When the restoration priority is calculated at the timing when an event occurs, the usage degree information acquisition unit 117 sets the time period from 12 hours after the time when the event occurs as the second time period, and acquires the average value of the usage degrees of the time periods included in the second time period. Specifically, when one unit is 1 hour and the event occurs at 1:17, the usage degree information acquisition unit 117 acquires the average value of the usage degree values from the 1 o'clock period to the 12 o'clock period as the usage degree information 126 of the second time period.

[0116] Note that the usage degree information 126 for the first time period is also referred to as short-term time period operability tendency. Also, the usage degree information 126 for the second time period is also referred to as long-term time period operability tendency. The usage degree information acquisition unit 117 outputs the acquired short-term time period operability tendency and long-term time period operability tendency to the calculation unit 118.

[0117] (Calculation unit 118) The calculation unit 118 calculates a variation value of the recovery priority according to the time when the event occurred for each recovery target R.

[0118] Here, the calculation unit 118 calculates the variation value based on the usage degree information 126 for one or a plurality of unit time periods after the time when the event occurred. For example, the calculation unit 118 calculates the variation value based on each of the usage degree information 126 for the first time period and each of the usage degree information 126 for the second time period. Specifically, the calculation unit 118 calculates the average value of the short-term time period operability tendency and the long-term time period operability tendency as the variation value. The calculation unit 118 outputs the variation value obtained by the calculation to the calculation unit 115.

[0119] The calculation unit 115 calculates the recovery priority based on the default value, the coefficient, and the variation value. Here, the variation value includes the variation value obtained by the calculation of the calculation unit 118. The calculation unit 115 may calculate the recovery priority using only the variation value obtained by the calculation of the calculation unit 118. Also, the calculation unit 115 may calculate the recovery priority using the variation value obtained by the calculation of the calculation unit 118 and the variation value specified based on the situation information 124 and the variation value information 125 of the recovery target R. Note that when the calculation unit 115 calculates the recovery priority using only the variation value obtained by the calculation of the calculation unit 118, the storage unit 12B does not necessarily store the situation information 124 and the variation value information 125.

[0120] For example, if the restoration target R is a facility such as a hospital, and an event occurs during the business hours of another hospital in the vicinity, there is an available hospital other than the hospital where the restoration target R is located. Also, if the restoration target R is a commercial facility or the like, and an event occurs during a time period when the number of users of the facility is small, even if the restoration priority of the facility decreases and the restoration is delayed, it is considered that the impact is relatively small. Therefore, when the time period in which the event occurs is the business hours of another facility such as a hospital in the vicinity, or a time period when the number of users of the facility is small, even if the restoration priority of the restoration target R decreases according to the fluctuation value and the restoration is delayed, it is considered that the impact is relatively small.

[0121] On the other hand, if the restoration target R is a facility such as a hospital and an event occurs during a time period when another hospital in the vicinity is not in business, since there is no available hospital other than the hospital where the restoration target R is located, it is preferable to avoid a decrease in the function of the hospital where the restoration target R is located. Also, if the restoration target R is a commercial facility or the like, and an event occurs during a time period when the number of users of the facility is large, it is considered that the impact is significant when the restoration priority of the facility decreases and the restoration is delayed. Therefore, when the time period in which the event occurs is a time period when another facility such as a hospital in the vicinity is not in business, or a time period when the number of users of the facility is large, it is considered preferable to set the restoration priority of the restoration target R to a high value.

[0122] Here, the restoration priority calculation system 100B calculates the restoration priority using the usage degree information 126 of the first time period. Thereby, the restoration priority calculation system 100B can calculate the restoration priority in consideration of the usage degree during a short period after the event occurs. For example, the restoration priority calculation system 100B can calculate a high restoration priority for a restoration target R with a high usage degree at the time when the event occurs or during a relatively short period from the time when the event occurs. Also, the restoration priority calculation system 100B can calculate a low restoration priority for a restoration target R with a low usage degree at the time when the event occurs or during a relatively short period from the time when the event occurs.

[0123] In addition, the recovery priority calculation system 100B calculates the recovery priority using the usage degree information 126 in the second time period. Thereby, the recovery priority can be calculated in consideration of the usage degree over a long period after the event occurs. For example, the recovery priority calculation system 100B can calculate a high recovery priority for the recovery target R with a high usage degree during a relatively long period from the time when the event occurs. Also, the recovery priority calculation system 100B can calculate a low recovery priority for the recovery target R with a low usage degree during a relatively long period from the time when the event occurs.

[0124] Note that in the recovery priority calculation system 100B, the recovery priority may be calculated using only one of the usage degree information 126 in the first time period or the usage degree information 126 in the second time period. In this case, the usage degree information acquisition unit 117 acquires only one of the usage degree information 126 in the first time period or the usage degree information 126 in the second time period, and the calculation unit 118 outputs the usage degree information 126 acquired by the usage degree information acquisition unit 117 as it is to the calculation unit 115 as a variation value.

[0125] <An example of the processing flow of the recovery priority calculation system 100B> Hereinafter, an example of the processing performed in the recovery priority calculation system 100B will be described with reference to FIG. 14. FIG. 14 is a flowchart for explaining an example of the processing performed in the recovery priority calculation system 100B. Note that the processing in steps S11 to S13 in FIG. 14 is the same as the processing in steps S1 to S3 in FIG. 6, and thus the description here is omitted.

[0126] After step S13, the usage degree information acquisition unit 117 refers to the storage unit 12 and acquires the usage degree information 126 of the restoration target R (S14). Subsequently, the usage degree information acquisition unit 117 specifies the short-term time zone operability tendency, which is the usage degree information 126 in the first time zone, among the usage degree information 126 of the restoration target R (S15). For example, the usage degree information acquisition unit 117 may set the time zone from the time when the usage degree information acquisition unit 117 specifies the short-term time zone operability tendency to 4 hours later as the first time zone, and specify the average value of the values indicating the usage degree in the first time zone as the short-term time zone operability tendency. Also, the usage degree information acquisition unit 117 specifies the long-term time zone operability tendency, which is the usage degree information 126 in the second time zone, among the usage degree information 126 of the restoration target R (S16). For example, the usage degree information acquisition unit 117 may set the time period from the time when the usage degree information acquisition unit 117 specifies the long-term time zone operability tendency to 12 hours later as the second time zone, and specify the average value of the values indicating the usage degree in the second time zone as the long-term time zone operability tendency. The usage degree information acquisition unit 117 outputs the specified short-term time zone operability tendency and long-term time zone operability tendency to the calculation unit 118.

[0127] The calculation unit 118 calculates a variation value of the restoration priority according to the time when the event occurs (S17: calculation step). Specifically, when the calculation unit 118 acquires the short-term time zone operability tendency and the long-term time zone operability tendency, the calculation unit 118 sets the average value of the values indicated by these pieces of information as the variation value of the restoration target R. The calculation unit 118 outputs the variation value obtained by the calculation to the calculation unit 115.

[0128] When the calculation unit 115 acquires the default value, the coefficient, and the variation value, the calculation unit 115 calculates the restoration priority of the restoration target R from the multiplication value based on the default value and the variation value (S18: calculation step). The method by which the calculation unit 115 calculates the restoration priority is the same as the processing of step S6 described with reference to FIG. 6 except that the value obtained by the calculation of the calculation unit 118 is used as the variation value.

[0129] Through the above processing, the recovery priority of the recovery target R is calculated. When there are multiple recovery targets R for which the recovery priority should be calculated, the recovery priority calculation system 100B performs the processing of steps S12 to S18 for each of the multiple recovery targets R. As a result, the recovery priority for each of the multiple recovery targets R is calculated.

[0130] Note that the recovery priority calculation system 100B may include the variation value acquisition unit 114 described in Embodiment 1. In this case, the calculation unit 115 may calculate the recovery priority of the recovery target R using not only the variation value obtained by the calculation of the calculation unit 118 but also the variation value acquired by the variation value acquisition unit 114.

[0131] 〔Embodiment 4〕 Hereinafter, the recovery priority calculation system 100C according to Embodiment 4 will be described. The recovery priority calculation system 100C calculates a variation value based on information indicating how often the facility is used and how far it has moved during normal times, and calculates the recovery priority using the variation value obtained as a result of the calculation.

[0132] FIG. 15 is a block diagram showing the configuration of the recovery priority calculation system 100C according to Embodiment 4. As shown in FIG. 15, the recovery priority calculation system 100C is different from the recovery priority calculation system 100B according to Embodiment 3 in that it includes a calculation device 1C instead of the calculation device 1B. Further, the calculation device 1C is different from the calculation device 1B in that it includes a control unit 11C and a storage unit 12C.

[0133] As shown in FIG. 15, the control unit 11C is different from the control unit 11B of the calculation device 1B in that it includes a frequency information acquisition unit 119 and a distance information acquisition unit 120 instead of the utilization degree information acquisition unit 117, and includes a calculation unit 118C instead of the calculation unit 118. Further, the storage unit 12C is different from the storage unit 12B of the calculation device 1B in that it stores frequency information 127 and distance information 128 instead of the utilization degree information 126.

[0134] In Embodiment 4, the restoration target R involves operations, and the storage unit 12C stores, for each restoration target R, frequency information 127 indicating the average number of operations per month and distance information 128 indicating the average moving distance per month.

[0135] The distance information 128 is an index indicating the moving distance of the facility per month, and the storage unit 12C stores distance information 128 corresponding to a plurality of facilities respectively. For example, the distance information 128 is represented by a value between 0 and 100, and the larger the value, the more the moving distance per month.

[0136] The distance information 128 may be an index based on the total moving distance of the facility in one month. In this case, the storage unit 12C may store, as the distance information 128 of a certain facility, an index indicating the moving distance of the facility per month for twelve months. Further, the distance information 128 may be an index indicating one value corresponding to the average value of the moving distance per month based on the total moving distance of the facility in one year.

[0137] The frequency information 127 is an index indicating the number of operations of the facility per month, and the storage unit 12C stores frequency information 127 corresponding to a plurality of facilities respectively. For example, the distance information 128 is represented by a value between 0 and 100, and the larger the value, the more the number of operations per month.

[0138] The frequency information 127 may be an index based on the total number of operations of the facility in one month. In this case, the storage unit 12C may store, as the frequency information 127 of a certain facility, an index indicating the number of operations of the facility per month for twelve months. Further, the frequency information 127 may be an index indicating one value corresponding to the average value of the number of operations per month based on the total number of operations of the facility in one year.

[0139] Note that the value indicating the frequency information 127 of a certain month is also referred to as the monthly average operation frequency index. Also, the value indicating the distance information 128 of a certain month is also referred to as the monthly average moving distance index.

[0140] For example, the restoration target R is an elevator. The storage unit 12C may store, for each elevator unit number, an index representing the number of times the elevator is used per month as the frequency information 127. Further, the storage unit 12C may store, for each elevator unit number, an index representing the distance the elevator moves per month as the distance information 128.

[0141] The frequency information acquisition unit 119 acquires the frequency information 127. Specifically, the frequency information acquisition unit 119 refers to the storage unit 12C, acquires the monthly average operation frequency index for the month in which the event occurred, and outputs the acquired monthly average operation frequency index to the calculation unit 118C.

[0142] The distance information acquisition unit 120 acquires the distance information 128. Specifically, the distance information acquisition unit 120 refers to the storage unit 12C, acquires the monthly average movement distance index for the month in which the event occurred, and outputs the acquired monthly average movement distance index to the calculation unit 118C.

[0143] The calculation unit 118C calculates a variation value of the restoration priority for each restoration target R according to the timing when the event occurred. Here, the calculation unit 118C calculates the variation value based on the frequency information 127 and the distance information 128 for the month in which the event occurred. Specifically, the calculation unit 118C calculates the average value of the frequency information 127 and the distance information 128 as the variation value. The calculation unit 118C outputs the variation value obtained by the calculation to the calculation unit 115.

[0144] The calculation unit 115 calculates the restoration priority based on the default value, the coefficient, and the variation value. Here, the variation value includes the variation value obtained by the calculation of the calculation unit 118C. The calculation unit 115 may calculate the restoration priority using only the variation value obtained by the calculation of the calculation unit 118C. Further, the calculation unit 115 may calculate the restoration priority using the variation value obtained by the calculation of the calculation unit 118C and the variation value specified based on the status information 124 and the variation value information 125 of the restoration target R. Note that when the calculation unit 115 calculates the restoration priority using only the variation value obtained by the calculation of the calculation unit 118C, the storage unit 12C does not necessarily store the status information 124 and the variation value information 125.

[0145] When a recovery target with a large normal movement distance and a large number of operations stops, it is considered necessary to give priority to recovery over a recovery target R with a small normal movement distance and a small number of operations. Here, the recovery priority calculation system 100C according to Embodiment 4 calculates the recovery priority based on the monthly average operation count index and the monthly average movement distance index for the month in which the event occurred. Thereby, the recovery priority calculation system 100C can calculate the recovery priority so that the recovery priority of the recovery target R with a large value of the normal movement distance and the number of operations, that is, the recovery target R that is used more frequently in normal times, becomes a larger value. Therefore, the recovery priority calculation system 100C can calculate the recovery priority of the recovery target R more appropriately.

[0146] In the recovery priority calculation system 100C, the calculation unit 118C may calculate the variation value using only one of the monthly average operation count index or the monthly average movement distance index.

[0147] <An example of the processing flow of the recovery priority calculation system 100C> Hereinafter, an example of the processing performed in the recovery priority calculation system 100C will be described with reference to FIG. 16. FIG. 16 is a flowchart for explaining an example of the processing performed in the recovery priority calculation system 100C. Note that the processing in steps S21 to S23 in FIG. 16 is the same as the processing in steps S1 to S3 in FIG. 16, and thus the description thereof will be omitted here.

[0148] After step S23, the count information acquisition unit 119 refers to the storage unit 12 and acquires the count information 127 of the recovery target R for the month in which the event occurred (S24). Subsequently, the distance information acquisition unit 120 refers to the storage unit 12 and acquires the distance information 128 of the recovery target R for the month in which the event occurred (S25). The count information acquisition unit 119 and the distance information acquisition unit 120 output the acquired count information 127 and distance information 128 to the calculation unit 118C.

[0149] The calculation unit 118C calculates a variation value of the recovery priority according to the time when the event occurs (S26: calculation step). Specifically, when the calculation unit 118C acquires the frequency information 127 and the distance information 128 of the recovery target R for the month in which the event occurs, the average value of the values indicated by these pieces of information is set as the variation value of the recovery target R. The calculation unit 118C outputs the variation value obtained by the calculation to the calculation unit 115.

[0150] When the calculation unit 115 acquires the default value, the coefficient, and the variation value, it calculates the recovery priority of the recovery target R from the multiplication value based on the default value and the variation value (S27: calculation step). The method by which the calculation unit 115 calculates the recovery priority is the same as the processing of step S6 described with reference to FIG. 6 except that the value obtained by the calculation of the calculation unit 118C is used as the variation value.

[0151] Through the above processing, the recovery priority of the recovery target R is calculated. When there are a plurality of recovery targets R for which the recovery priority is to be calculated, the recovery priority calculation system 100B performs the processing of steps S22 to S27 for each of the plurality of recovery targets R. Thereby, the recovery priority for each of the plurality of recovery targets R is calculated.

[0152] Note that the recovery priority calculation system 100C may include the variation value acquisition unit 114 described in Embodiment 1. In this case, the calculation unit 115 may calculate the recovery priority of the recovery target R using, in addition to the variation value obtained by the calculation of the calculation unit 118C, the variation value acquired by the variation value acquisition unit 114.

[0153] [Modification Example] In the above-described Embodiment 3, the configuration for calculating the variation value using the values indicating the short-term time zone operability improvement and the long-term time zone operability improvement has been described. Further, in Embodiment 4, the configuration for calculating the variation value using the monthly average operation frequency index and the monthly average moving distance index has been described. Here, the method for calculating the variation value is not limited to those described above.

[0154] For example, the calculation unit 118C may calculate a variation value using all of the short-term time zone operability improvement, long-term time zone operability improvement, monthly average operation frequency index, and monthly average moving distance index. Specifically, the calculation unit 118C may calculate the variation value using the following formula (6). Variation value = [({(Monthly average operation frequency index)+(Monthly average moving distance index)}×(1 / 2))]×[({(Short-term time zone operability improvement)+(Long-term time zone operability improvement)}×(1 / 2))]×(Correction coefficient) ··· Formula (6)

[0155] In the above formula (6), the correction coefficient is a coefficient for correcting the variation value calculated based on the above formula (6) to an appropriate magnitude as the value to be substituted into formula (1). Any value can be adopted as the correction coefficient. For example, when the value before multiplying by the correction coefficient is larger than the specified value in formula (1), a value of 1 or less (for example, 1 / 10, 1 / 100, etc.) can be adopted as the correction coefficient.

[0156] In the above formula (6), although the value obtained by simply averaging the operation frequency index and the moving distance index is used, it is not limited to this. For example, the average value of these after multiplying different weight coefficients (for example, 0.7 and 0.3) to the operation frequency index and the moving distance index may be used. Also, in the above formula (6), although the value obtained by simply averaging the short-term time zone operability improvement and the long-term time zone operability improvement is used, it is not limited to this. For example, the average value of these after multiplying different weight coefficients (for example, 0.6 and 0.4) to the short-term time zone operability improvement and the long-term time zone operability improvement may be used.

[0157] By calculating using the short-term time zone operability improvement, long-term time zone operability improvement, monthly average operation frequency index, and monthly average moving distance index, a variation value reflecting how much the recovery target R is utilized if it is normal can be obtained at the timing when the recovery priority is calculated. By calculating the recovery priority using such a variation value, it is possible to increase the recovery priority of the recovery target R for which a high utilization rate is expected if no event has occurred. 〔Modification example〕 The execution entity of each process described in each of the above embodiments is arbitrary and is not limited to the above examples.
