Description

[Technical field]

[0001] The present disclosure relates to an inspection route plan proposing system and an inspection route plan proposing method for proposing an inspection route plan for inspecting a plurality of devices installed in an inspection target area. [Background technology]

[0002] For example, patrol inspections of plants such as thermal power plants involve a variety of tasks, such as palpation, reading meters such as analog meters, detecting abnormal sounds, and checking for steam leaks. These tasks may need to be performed several times a day in shifts, and if they are performed by patrol personnel (people), there are issues such as increased inspection costs and a shortage of people. As a measure to reduce the inspection costs of patrol inspections, attempts have been made to digitize the measured values ​​of analog meters and other instruments using wireless sensors and send them to mobile devices carried by patrol personnel via wireless communication using the wireless sensors.

[0003] Patent Document 1 discloses a system that optimizes inspection routes during on-site inspections of plants using mobile terminals, and when abnormalities or information requiring caution is obtained about equipment within a specified inspection route, the system refers to maintenance management history information, etc., and then performs additional inspections of equipment outside the inspection route.

[0012] Fig. 1 is a flow diagram of an inspection route plan proposing method according to an embodiment of the present disclosure. Fig. 2 is a schematic diagram showing a configuration of an inspection route plan proposing method according to an embodiment of the present disclosure. Fig. 3 is an explanatory diagram for explaining an inspection route plan in an embodiment of the present disclosure.

[0013] (Inspection route planning method) An inspection route plan proposing method 100 according to some embodiments is a method for proposing an inspection route plan RP for inspecting a plurality of devices 2 (see FIG. 2) installed in an inspection target area 1. As shown in FIG. 1, the inspection route plan proposing method 100 at least includes an inspection result information acquisition step S1, a damage risk calculation step S2, an inspection required time calculation step S3, and an inspection route plan presentation step S4. As shown in FIG. 1, the inspection route plan proposing method 100 may further include an inspection route plan determination step S5, an inspection step S6, and an inspection result information input step S7. Hereinafter, an example will be described in which each of the plurality of devices 2 includes plant devices constituting a plant (factory equipment), and the inspection target area 1 includes the site of the plant.

[0014] At least one step in the inspection route plan proposal method 100 may be performed by the inspection route plan proposal system 10 (see FIG. 2), by a device or equipment other than the inspection route plan proposal system 10, or manually.

[0015] 3, the inspection route plan RP includes at least one inspection target device 2T to be inspected among a plurality of devices 2 installed in the inspection target area 1, inspection implementation items AE which are inspection items E to be performed on the inspection target device 2T, and a total inspection required time TTR required to inspect the inspection implementation items AE on at least one inspection target device 2T. The total inspection required time TTR is the time required to inspect all inspection implementation items AE included in the inspection route plan RP, and is calculated by adding up the inspection required times TR of all inspection implementation items AE included in the inspection route plan RP.

[0016] As shown in FIG. 3, inspection item E includes sensing of device 2, taking a photograph of device 2, checking the operation of device 2, and the like.

[0017] In the inspection route plan determination step S5, the inspection route plan RP (the equipment to be inspected 2T and the inspection implementation items AE) is determined. In the inspection step S6, an inspection is performed according to the inspection route plan RP determined in the inspection route plan determination step S5. That is, in the inspection step S6, an inspection of the inspection implementation items AE is performed on the equipment to be inspected 2T included in the inspection route plan RP. The inspection in the inspection step S6 provides an inspection result R of the equipment to be inspected 2T. The inspection result R includes a determination result as to whether the equipment to be inspected 2T is normal or abnormal.

[0018] In the inspection result information input step S7, the inspection result R of at least one inspection target device 2T (device 2) obtained by the inspection in the inspection step S6 and the inspection work time WT for each inspection implementation item AE (inspection item E) are input. The inspection result R and the inspection work time WT may be input by the inspector who performed the inspection in the inspection step S6.

[0019] The inspection results R and the inspection work time WT input in the inspection result information input step S7 are stored in the inspection result information storage unit 11. By repeatedly performing steps ranging from the inspection route plan determination step S5 to the inspection result information input step S7, the inspection result information storage unit 11 accumulates the inspection results R of each of the multiple devices 2 installed in the inspection target area 1 and the inspection work time WT for each inspection item E. As a result, the inspection result information storage unit 11 stores the inspection results R of each of the multiple devices 2 and the inspection work time WT for each inspection item E.

[0020] In the inspection result information acquisition step S1, the inspection results R and the inspection work time WT for each inspection item are acquired for each of the multiple devices 2. The inspection results R and the inspection work time WT are acquired from the inspection result information storage unit 11.

[0021] In the damage risk calculation step S2, a damage risk RD (mean time between failures, MTBF in the illustrated example) of each of the multiple devices 2 is calculated based on the inspection results R acquired in the inspection result information acquisition step S1. In the illustrated embodiment, the damage risk calculation step S2 is performed by the damage risk calculation unit 12. The damage risk calculation unit 12 is configured to calculate a damage risk RD (mean time between failures, MTBF in the illustrated example) of each of the multiple devices 2 based on the inspection results R stored in the inspection result information storage unit 11.

[0022] The damage risk calculation unit 12 performs statistical processing on the inspection results R to calculate the damage risk RD (mean time between failures MTBF) of each of the multiple devices 2. Examples of the damage risk RD include the mean time between failures MTBF, which is the average interval between failures of the devices 2 and the next failure, and the failure frequency rate, which is the reciprocal of the mean time between failures MTBF, as shown in Fig. 3. A device 2 with a short mean time between failures MTBF has a high damage risk RD, and a device 2 with a long mean time between failures MTBF has a low damage risk RD.

[0023] In the inspection required time calculation step S3, based on the inspection work time WT acquired in the inspection result information acquisition step S1, the inspection required time TR for each inspection item E of each of the multiple devices 2 is calculated. In the illustrated embodiment, the inspection required time calculation step S3 is performed by the inspection required time calculation unit 13. The inspection required time calculation unit 13 is configured to calculate the inspection required time TR for each inspection item E of each of the multiple devices 2 based on the inspection work time WT stored in the inspection result information storage unit 11.

[0024] The inspection required time calculation unit 13 performs statistical processing on the inspection work time WT for each inspection item E of each of the multiple devices 2, thereby calculating the inspection required time TR for each inspection item E of each of the multiple devices 2. The inspection required time calculation unit 13 may take, for example, an average value or a median value of the inspection work times WT as the inspection required time TR.

[0025] In the inspection route plan presentation step S4, a plurality of inspection route plans RP each having different at least one of the inspection target equipment 2T or the inspection implementation items AE is presented in consideration of the damage risk RD and the required inspection time TR. That is, in the inspection route plan presentation step S4, a plurality of inspection route plans RP each having different at least one of the inspection target equipment 2T or the inspection implementation items AE is created in consideration of the damage risk RD and the required inspection time TR, and the created plurality of inspection route plans RP is presented.

[0026] In the illustrated embodiment, the inspection route plan presentation step S4 is performed by the inspection route plan presentation unit 14. The inspection route plan presentation unit 14 is configured to be able to present a plurality of inspection route plans RP in which at least one of the inspection target equipment 2T or the inspection implementation items AE is different, taking into consideration the damage risk RD and the inspection required time TR. The inspection route plan presentation unit 14 includes a creation unit 15 configured to create a plurality of inspection route plans RP in which at least one of the inspection target equipment 2T or the inspection implementation items AE is different, taking into consideration the damage risk RD calculated in the damage risk calculation unit 12 and the inspection required time TR calculated in the inspection required time calculation unit 13, and a presentation unit 16 configured to present the plurality of inspection route plans RP created in the creation unit 15. The presentation unit 16 includes a display screen 161 and is configured to display a plurality of inspection route plans RP on the display screen 161.

[0027] In the above-mentioned inspection route plan determination step S5, one inspection route plan RP selected from the multiple inspection route plans RP presented in the inspection route plan presentation step S4 may be determined as the inspection route plan RP to be used for inspection.

[0028] According to the above method, in the inspection route plan presentation step S4, a plurality of inspection route plans RP are presented, each of which differs in at least one of the equipment to be inspected 2T or the inspection implementation items AE. Each of the plurality of inspection route plans RP presented in the inspection route plan presentation step S4 takes into consideration the damage risk RD and the inspection time required TR of each of the plurality of equipment 2. Therefore, by performing an inspection according to one inspection route plan RP selected from the plurality of inspection route plans RP, it is possible to focus on inspecting equipment 2 with a high damage risk RD, and to reduce excessive inspection costs.

[0029] (Inspection route planning proposal system) An inspection route plan proposal system 10 according to some embodiments is for proposing the above-mentioned inspection route plan RP. As shown in Fig. 2, the inspection route plan proposal system 10 includes at least the above-mentioned inspection result information storage unit 11, the above-mentioned damage risk calculation unit 12, the above-mentioned inspection required time calculation unit 13, and the above-mentioned inspection route plan presentation unit 14.

[0030] According to the above configuration, the inspection route plan presentation unit 14 presents a plurality of inspection route plans RP, each of which differs in at least one of the equipment to be inspected 2T or the inspection implementation items AE. Each of the plurality of inspection route plans RP presented by the inspection route plan presentation unit 14 takes into consideration the damage risk RD and the inspection time required TR of each of the plurality of equipment 2. Therefore, by having an inspector carry out an inspection according to one inspection route plan RP selected from the plurality of inspection route plans RP, it is possible to focus on inspecting equipment 2 with a high damage risk RD, and to reduce excessive inspection costs.

[0031] (How to create an inspection route plan) As shown in Fig. 3, among the multiple devices 2 installed in the inspection area 1, devices that have been preset as inspection targets are defined as set devices 2S, and devices other than the set devices 2S whose damage risk is equal to or greater than a predetermined risk are defined as high-risk devices 2H. Among the multiple devices 2 installed in the inspection area 1, devices other than the set devices 2S whose damage risk is less than a predetermined risk are defined as low-risk devices 2L.

[0032] In the illustrated embodiment, the set devices 2S include devices 2 whose inspection intervals are preset by law or the like. The high-risk devices 2H are made up of devices 2 other than the set devices 2S whose mean time between failures (MTBF) is equal to or less than a predetermined mean time between failures (10,000 hr / time in the illustrated example). The low-risk devices 2L are made up of devices 2 other than the set devices 2S whose mean time between failures (MTBF) exceeds a predetermined mean time between failures (10,000 hr / time in the illustrated example).

[0033] Fig. 4 is a flow diagram of a method for creating an inspection route plan. Fig. 5 is an explanatory diagram for explaining an example of a method for creating an inspection route plan. In some embodiments, the above-mentioned creation unit 15 is configured to create each of a plurality of inspection route plans RP by a creation method 200 as shown in Fig. 4.

[0034] Specifically, the creation unit 15 adds all set devices 2S to the inspection targets in the inspection route plan RP (S41). Next, the creation unit 15 determines whether or not there is high-risk device 2H that is not included in the inspection route plan RP (S42), and if there is high-risk device 2H ("YES" in S42), determines whether or not it is possible to add high-risk device 2H to the inspection targets (S43). The creation unit 15 may randomly extract the high-risk device (high-risk device to be determined) 2H to be determined in S42 from among the multiple high-risk devices 2H, or may extract them in order of increasing risk.

[0035] Whether or not the high-risk equipment (high-risk equipment to be determined) 2H can be added to the inspection target can be determined based on whether or not the total time, which is the sum of the inspection required time TR of each of all the inspection implementation items AE included in the inspection route plan RP at the time of determination and the total of the inspection required time TR of each of the inspection implementation items AE of the high-risk equipment 2H, is equal to or less than the preset required time STR. If the total time is equal to or less than the set required time STR, the creation unit 15 determines that the high-risk equipment 2H can be added to the inspection target ("YES" in S43), and adds the high-risk equipment 2H to the inspection target (S44). If the total time exceeds the set required time STR, the creation unit 15 determines that the high-risk equipment 2H cannot be added to the inspection target ("NO" in S43), and does not add the high-risk equipment 2H to the inspection target.

[0036] The creation unit 15 determines whether or not there is any high-risk equipment 2H that is not included in the inspection route plan RP (S42), and if there is no high-risk equipment 2H ("NO" in S42), determines whether or not it is possible to add low-risk equipment 2L to the inspection target (S45). The creation unit 15 may randomly extract the low-risk equipment (determination target low-risk equipment) 2L to be determined in S45 from among the multiple low-risk equipment 2L, or may extract it in order of increasing risk.

[0037] Whether or not a low-risk device (determination target low-risk device) 2L can be added to the inspection target can be determined by whether or not the total time of the sum of the inspection required time TR of each of all the inspection implementation items AE included in the inspection route plan RP at the time of determination and the sum of the inspection required time TR of each of the inspection implementation items AE of the low-risk device 2L is equal to or less than the preset required time STR. If the total time is equal to or less than the set required time STR, the creation unit 15 determines that the low-risk device 2L can be added to the inspection target ("YES" in S45), and adds the low-risk device 2L to the inspection target (S46). If the total time exceeds the set required time STR, the creation unit 15 determines that the low-risk device 2L cannot be added to the inspection target ("NO" in S45), and does not add the low-risk device 2L to the inspection target.

[0038] In some embodiments, when, among the above-mentioned multiple devices 2, devices that have been preset as inspection targets are defined as set devices 2S, and devices other than the set devices 2S whose damage risk RD is a predetermined risk or higher are defined as high-risk devices 2H, the above-mentioned inspection route plan presentation unit 14 is configured to present, as at least one inspection route plan RP among the multiple inspection route plans RP, a short-term route plan RP in which the total inspection time TTR is equal to or less than the set time STR, and in which the set devices 2S and at least one high-risk device 2H are the inspection target devices 2T.

[0039] The creation unit 15 may be configured to create a plurality of inspection route plans RP (RP1, RP2) having different total inspection times TTR as shown in FIG. 5 by the above-mentioned creation method 200. The creation unit 15 may be configured to create a first inspection route plan RP1 in which the total inspection time TTR is equal to or less than a first set required time STR1 (STR), and a second inspection route plan RP2 in which the total inspection time TTR exceeds the first set required time STR1 and is equal to or less than a second set required time STR2 (STR) longer than the first set required time STR1. Each of the first inspection route plan RP1 and the second inspection route plan RP2 includes a set device 2S and at least one high-risk device 2H as the inspection target device 2T. The second set required time STR2 is set to be equal to or shorter than the inspection work available time, which is the time available for engaging in inspection work.

[0040] According to the above configuration, by inspectors carrying out inspections according to the short-time route plans RP1 and RP2, they can inspect not only the set devices 2S but also at least one high-risk device 2H having a high damage risk RD. In addition, since the total inspection required time TTR of the short-time route plans RP1 and RP2 is equal to or less than the set required time STR, it is possible to prevent the time spent by inspectors carrying out inspections according to the short-time route plans RP1 and RP2 on inspection work from becoming too long and exceeding the set required time STR.

[0041] In some embodiments, the above-mentioned inspection route plan presenting unit 14 may be configured to present an inspection route plan RP that includes the set device 2S and all high-risk devices 2H as the inspection target devices 2T and does not include the low-risk device 2L as one of the multiple inspection route plans RP. According to the above configuration, an inspector performs an inspection according to the inspection route plan RP that includes the set device 2S and all high-risk devices 2H as the inspection target devices 2T, and therefore appropriate inspection is performed on all high-risk devices 2H, thereby improving the reliability of the multiple devices 2.

[0042] In some embodiments, the above-mentioned inspection route plan presenting unit 14 may be configured to present a preset inspection route plan SRP (see FIG. 5) in addition to the multiple inspection route plans RP. The preset inspection route plan SRP is preset, for example, in a plant in which the equipment 2 to be inspected is installed, or in a plant of the same type as the plant. In FIG. 5, the total inspection time TTR of the set inspection route plan SRP is longer than the total inspection time TTR of the second inspection route plan RP2. According to the above configuration, since each of the multiple inspection route plans RP can be compared with the set inspection route plan SRP, it is useful when determining the inspection route plan RP to be used for inspection.

[0043] (Individual inspection route plan) Fig. 6 is an explanatory diagram for explaining an inspection route plan according to an embodiment of the present disclosure. Fig. 7 is an explanatory diagram for explaining an example of a method for creating an inspection route plan. Fig. 8 is an explanatory diagram for explaining information related to an inspector.

[0044] In some embodiments, the above-mentioned inspection route plan proposal system 10 further includes an inspector information storage unit 21 (see FIG. 2) that stores information II about an inspector who performs an inspection of an inspection action item AE on at least one inspection target device 2T. The above-mentioned inspection route plan presentation unit 14 is configured to present an individual inspection route plan IRP, which is an inspection route plan RP for each inspector, when there are multiple inspectors.

[0045] In the illustrated embodiment, the above-mentioned creation unit 15 is configured to create a plurality of individual inspection route plans IRP in consideration of the information II about the inspectors stored in the inspector information storage unit 21. The information II about the inspectors includes information about the number of inspectors engaged in inspection, as shown in FIG. 6. The above-mentioned creation unit 15 creates an inspection route plan RP3, as shown in FIG. 7, in which the total inspection time TTR is equal to or less than the sum of the inspection work times of the plurality of inspectors (in the illustrated example, WAT1+WAT2), by the above-mentioned creation method 200. Then, the creation unit 15 creates individual inspection route plans IRP (IRP1, IRP2) for each of the plurality of inspectors by allocating the inspection target devices 2T and the inspection implementation items AE included in the inspection route plan RP3 to each of the plurality of inspectors so as not to exceed the inspection work available time WAT (WAT1, WAT2) of each of the inspectors. The creation unit 15 may directly create individual inspection route plans IRP (IRP1, IRP2) in which the respective total required inspection times TTR (TTR1, TTR2) are equal to or less than the respective available inspection work times WAT (WAT1, WAT2).

[0046] According to the above configuration, the individual inspection route plan IRP presented by the inspection route plan presenting unit 14 is an inspection route plan RP in which an inspection item AE is assigned to each of the multiple inspectors. Each of the multiple inspectors performs an inspection according to the individual inspection route plan IRP, thereby inspecting multiple pieces of equipment 2 including equipment 2 with a high damage risk RD, and preventing the multiple inspectors from spending too much time on their inspection work.

[0047] 8, the above-mentioned information II regarding the inspector includes information indicating inspectable items PE, which are inspection items E of each of the plurality of devices 2 that can be inspected by each inspector. The above-mentioned inspection route plan presenting unit 14 is configured to present the individual inspection route plan IRP in consideration of the information indicating the inspectable items PE.

[0048] The inspection items E that an inspector can appropriately perform may differ depending on the inspector's capabilities and experience. According to the above configuration, the individual inspection route plan IRP presented in the inspection route plan presenting unit 14 is an inspection route plan RP in which the above-mentioned inspectable items PE are assigned to each of the multiple inspectors. In the individual inspection route plan IRP, an inspector with sufficient capabilities and experience is assigned an inspection implementation item AE that cannot be performed by an inspector with little capabilities and experience. Therefore, in the individual inspection route plan IRP, an appropriate inspection implementation item AE is assigned according to the inspector's capabilities and experience. By each of the multiple inspectors performing an inspection according to the individual inspection route plan IRP including appropriate inspection implementation items (inspectable items PE), appropriate inspection is performed on each of the multiple devices 2, and the reliability of the multiple devices 2 can be improved.

[0049] In some embodiments, the inspection result information storage unit 11 stores inspectors and inspection work times WT in association with each other, and the inspection required time calculation unit 13 is configured to be able to calculate the inspection required time TR (see FIG. 8) for each inspector based on the inspection work time WT stored in the inspection result information storage unit 11. The inspection route plan presentation unit 14 is configured to present an individual inspection route plan IRP in consideration of the inspection required time TR for each inspector.

[0050] The inspection work time WT for each inspection item E may differ depending on the inspector's ability and experience. According to the above configuration, the individual inspection route plan IRP presented by the inspection route plan presentation unit 14 is an inspection route plan RP in which an inspection implementation item AE is assigned to each of the multiple inspectors, taking into consideration the inspection time TR required for each inspector. In the individual inspection route plan IRP, an inspector with sufficient ability and experience is assigned many inspection implementation items AE because the inspection time TR required for each inspection item E tends to be shorter than that of an inspector with little ability and experience. Therefore, in the individual inspection route plan IRP, appropriate inspection implementation items AE are assigned according to the inspector's ability and experience. By each of the multiple inspectors performing an inspection according to the individual inspection route plan IRP including the appropriate inspection implementation items AE, it is possible to prevent the time that the inspector spends on the inspection work from being too long or too short.

[0051] In some embodiments, the above-mentioned information II on the inspectors includes information indicating an available inspection work time WAT (see FIG. 7), which is the time when each inspector can engage in inspection work. The above-mentioned inspection route plan presenting unit 14 is configured to present the individual inspection route plan IRP in consideration of the information indicating the available inspection work time WAT.

[0052] For example, the multiple inspectors may include non-full-time inspectors, and the available inspection work time WAT, which is the time that each inspector can engage in inspection work, may differ. According to the above configuration, the individual inspection route plan IRP presented by the inspection route plan presenting unit 14 takes into consideration the available inspection work time WAT of each of the multiple inspectors. An inspection item E is assigned to each of the multiple inspectors so that the total inspection time (TTR) falls within the available inspection work time WAT (WAT1, WAT2). By each of the multiple inspectors performing inspection according to the individual inspection route plan IRP including the inspection item E, it is possible to prevent the inspection work time WT of each of the multiple inspectors from becoming too long and exceeding the available inspection work time WAT.

Each of FIGS. 11 to 13 is an explanatory diagram for explaining the update of the inspection route plan when an abnormality is determined. As shown in FIG. 10, the above-mentioned inspection route plan proposal method 100 may further include an inspection target device addition step S8 in which, when an abnormality determination is input as the inspection result R in the inspection result information input step S7 ("YES" in S81), an inspection route plan RP is updated so that an individual inspection route plan IRP different from the individual inspection route plan IRP for the inspector who input the inspection result R includes an appliance 2 whose degree of association with the appliance 2 for which the abnormality determination is input is equal to or greater than a predetermined degree of association.

[0054] In the illustrated embodiment, the inspection target device addition step S8 is performed by the inspection result information input unit 32 (see FIG. 9). In some embodiments, as shown in FIG. 9, the above-described inspection route plan proposal system 10 further includes an equipment association storage unit 31, an inspection result information input unit 32, and an inspection route plan update unit 33.

[0055] The device association degree storage unit 31 stores an association degree indicating the degree of relationship between a plurality of devices 2. Among the plurality of devices 2, the association degree between devices 2 of the same or similar type is higher than the association degree between devices 2 of different types. Also, among the plurality of devices 2, the association degree between devices 2 of the same or similar use is higher than the association degree between devices 2 of different uses.

[0056] The inspection result information input unit 32 is configured to be able to input the inspection results R of each of the multiple devices 2 and the inspection work time WT for each inspection item E. The inspection results R and the inspection work time WT input by the inspection result information input unit 32 are stored in the inspection result information storage unit 11.

[0057] The inspection route plan update unit 33 is configured to, when an abnormality determination is input as the inspection result R to the inspection result information input unit 32, update the inspection route plan RP to include an equipment 2 (2R) whose degree of association with the equipment 2 (2E) for which the abnormality determination was input is equal to or greater than a predetermined degree of association in an individual inspection route plan IRP that is different from the individual inspection route plan IRP for the inspector who input the inspection result R.

[0058] When an abnormality determination is input as the inspection result R by the inspection result information input unit 32 ("YES" in S81), the inspection route plan update unit 33 determines whether or not there is any device 2R whose degree of association with the device 2E for which the abnormality determination was input is equal to or greater than a predetermined degree of association (S82). When there is any device 2R whose degree of association is equal to or greater than the predetermined degree of association in the above determination ("YES" in S82), the inspection route plan update unit 33 adds the device 2R as an inspection target to an individual inspection route plan IRP different from the individual inspection route plan IRP for which the device 2E is an inspection target (S83).

[0059] Hereinafter, a specific example will be described with reference to Figs. 11 to 13.

The device 2R is of the same type as the device 2E and has the same purpose as the device 2E, so that the degree of association with the device 2E is equal to or greater than a predetermined degree of association. Here, the same type of equipment includes equipment of the same model as the above equipment but installed in a different location. The similar equipment includes equipment of a different model from the above equipment.

[0060] Inspection routes IR1 and IR2 are shown according to the respective inspection route plans in Fig. 11 to Fig. 13. Equipment 2R is not included in the inspection targets before the update of the inspection route plan including the facilities shown in Fig. 12. When an abnormality is determined for equipment 2E shown in Fig. 11, equipment 2R, whose degree of association with equipment 2E is equal to or greater than a predetermined degree of association, is added to the inspection targets as shown in Fig. 13, and inspection route IR2 is changed to pass through equipment 2R.

[0061] During inspection, the equipment 2 (2R) that is highly related to the equipment 2 (2E) in which an abnormality has been detected is likely to have a similar abnormality. According to the above configuration, the inspection route plan update unit 33 can include the equipment 2 (2R) that is highly related to the equipment 2 (2E) in which an abnormality has been detected as an inspection target in the individual inspection route plan IRP of an inspector other than the inspector who detected the abnormality in the equipment 2 (2E). This makes it possible to have the inspector inspect the equipment 2 (2R) that is highly related. According to the above configuration, the inspection of the equipment 2 (2R) that is highly related to the equipment 2 (2E) in which an abnormality has been detected is promptly performed, so that the reliability of the multiple equipment 2 can be improved.
