[Description of management method]
FIG. 3 is a schematic diagram of a management method executed by the management system S according to the present embodiment. When a failure occurs in the device E, the user U1 of the device E contacts the administrator U2 by telephone or e-mail. The administrator U2 uses the administrator terminal 2 to input a situation regarding the recovery work (a).

  In the management device 1, the status acquisition unit 111 acquires status information indicating a status related to the recovery work from the administrator terminal 2. The situation regarding the recovery work is, for example, the content of the failure that has occurred in the device E, the position of the device E, and the position of the worker U3 who performs the recovery work. The time calculation unit 112 calculates the expected recovery time based on the status related to the recovery work acquired by the status acquisition unit 111 (b). The time calculation unit 112 causes the storage unit 13 to store the calculated expected recovery time.

  In order to calculate the expected recovery time, the time calculation unit 112 prepares for the preparation of the recovery work by the worker U3, and the movement for the movement from the position of the worker U3 to the position of the apparatus E (that is, the work place). Based on the time and the work time required for the recovery work, an initial recovery expected time is calculated. When the equipment E related to the failure is installed at a plurality of bases, the travel time may include a travel time between the plurality of bases, and the work time may include a work time at the plurality of bases. The time calculation unit 112 does not use progress information described later in calculating the initial recovery expected time.

  The time calculation unit 112 determines a fixed value set in advance in the management apparatus 1 as the preparation time. Alternatively, the time calculation unit 112 may determine the preparation time based on the content of the failure or the content of the recovery work.

  The time calculation unit 112 determines the travel time based on the position of the worker U3, the position of the device E, and the transportation means used by the worker U3. The position of the worker U3 may be the office or home position where the worker U3 normally stays at that time, or may be the position indicated by the position information that the worker terminal 4 periodically transmits to the management device 1. For example, the time calculation unit 112 reads a preset transportation means used by the worker U3, estimates the time required to move from the position of the worker U3 using the transportation means to the position of the apparatus E, and travel time Determine as. The time calculation unit 112 can use a known movement route and required time estimation technique in order to determine the movement time.

  The time calculation unit 112 determines the work time based on the content of the failure that has occurred in the device E. For example, the time calculation unit 112 reads the actual time taken for recovery work for a similar failure that occurred in the past from the storage unit 13, and calculates a statistical value (average value, median or mode) of the actual time, Determine as working time.

  The time calculation unit 112 calculates the initial expected recovery time by adding the preparation time, movement time, and work time determined as described above to the current time. The initial expected recovery time includes a scheduled time for completing each stage (for example, preparation, movement, and recovery work) leading to the recovery, and a scheduled time for completing the recovery. The time calculation unit 112 is not limited to the specific calculation method shown here, and may calculate the expected recovery time by other methods.

  The accuracy specifying unit 113 specifies the accuracy of the expected recovery time when the time calculation unit 112 calculates the expected recovery time. The accuracy specifying unit 113 specifies a fixed value (for example, 20%) preset in the management apparatus 1 as the accuracy for the initial expected recovery time. The accuracy specifying unit 113 stores the specified accuracy in the storage unit 13.

  The accuracy specifying unit 113 may specify the accuracy based on the situation regarding the recovery work. The accuracy specifying unit 113 specifies, for example, a value corresponding to the content of the failure as the accuracy. Thereby, the accuracy specifying unit 113 can set the initial accuracy high for a failure that is easy to recover, and can set the initial accuracy low for a failure that is difficult to recover. The accuracy specifying unit 113 specifies, for example, a value corresponding to the distance between the position of the worker U3 and the position of the apparatus E as the accuracy. As a result, the accuracy specifying unit 113 sets the initial accuracy high when the worker U3 is near the device E, so that the movement delay is difficult to occur, and when the worker U3 is far from the device E, The initial accuracy can be set low considering the movement delay.

  The output unit 114 outputs the expected recovery time calculated by the time calculation unit 112 and the accuracy specified by the accuracy specifying unit 113 to the user U1 (c). The output unit 114 may output the expected recovery time and accuracy to the administrator U2 and the worker U3.

  The output unit 114 provides the expected recovery time and accuracy to the display device (that is, the display unit included in the administrator terminal 2, the user terminal 3, and the worker terminal 4) accessible to the user U1, the administrator U2, or the worker U3. It may be displayed. The output unit 114 transmits an e-mail, a message, etc. to the administrator terminal 2, the user terminal 3 or the worker terminal 4 corresponding to the user U1, the administrator U2 or the worker U3, and the recovery expected time and The accuracy may be notified. The output unit 114 may print the expected recovery time and accuracy on paper using a printer.

  The output unit 114 preferably outputs the initial expected recovery time calculated by the time calculation unit 112 before the recovery operation is started within a predetermined time from the occurrence time of the failure. Thereby, the expected recovery time can be notified to the user U1 at an early stage, and the satisfaction degree of the user U1 can be improved.

  FIG. 4A is a front view of the user terminal 3 displaying information from the management apparatus 1 according to the present embodiment. When the user terminal 3 receives information indicating the initial recovery expected time and accuracy from the management device 1, the user terminal 3 displays the initial recovery expected time T1 and accuracy A on the display unit according to the information. The accuracy A may be the accuracy value (percentage) itself, and the text associated with the accuracy value (for example, the first report, the second report,. (A character string such as a complete report). Thereby, the management apparatus 1 can notify the user U1 of the initial expected recovery time early. Further, the management device 1 informs the user U1 that the accuracy of the initial recovery expected time is low, so that the recovery expected time is assumed to change later. Similarly, the manager terminal 2 and the worker terminal 4 may display the initial expected recovery time T1 and the accuracy A.

  The worker U3 notifies the manager U2 of the progress of the recovery by telephone or e-mail. The administrator U2 inputs the progress of recovery using the administrator terminal 2 (d). The worker U3 may input the progress of the recovery using the worker terminal 4.

  In the management device 1, the recovery expectation acquisition unit 115 reads out and acquires the initial recovery expected time calculated by the time calculation unit 112 from the storage unit 13. Further, the progress acquisition unit 116 acquires progress information indicating the progress of recovery from the administrator terminal 2 or the worker terminal 4. The progress of recovery is, for example, information indicating whether each stage (for example, preparation, movement, and recovery work) leading to the recovery is completed and the time when each stage is completed.

  The progress acquisition unit 116 may automatically determine the progress of recovery. The progress acquisition unit 116 determines the progress of recovery by comparing the current position of the worker U3 with the position of the apparatus E, for example. In this case, the position of the worker U3 is acquired based on the position information that the worker terminal 4 periodically transmits to the management device 1. The progress acquisition unit 116 reflects in the progress where the worker U3 is on the route from the departure position of the worker U3 to the device E.

  Furthermore, after the worker U3 reaches the apparatus E, the progress acquisition unit 116 reflects the ratio between the staying time of the worker U3 at the place and the scheduled time for the recovery work in the progress. For example, when the stay time is 1.2 times the scheduled time (that is, the time during which the worker U3 is staying near the position of the apparatus E has passed the scheduled time for the recovery work). In the case), the progress is judged as being 20% behind the scheduled time. On the other hand, the progress acquisition unit 116, when the stay time is 0.8 times the scheduled time (that is, the time during which the worker U3 is staying in the vicinity of the position of the apparatus E falls within the scheduled time for the recovery work) In the case where the current time is 20% earlier than the scheduled time.

  The progress acquisition unit 116 is not limited to the specific method shown here, and may automatically determine the progress of recovery by other methods.

  The time calculation unit 112 recalculates the recovery expected time based on the initial recovery expected time acquired by the recovery expected acquisition unit 115 and the recovery progress acquired by the progress acquisition unit 116 (e). The time calculation unit 112 stores the recalculated recovery expected time in the storage unit 13.

  In order to recalculate the expected recovery time, the time calculation unit 112 includes a scheduled time for completing each stage (for example, preparation, movement, and recovery work) indicated by the expected recovery time acquired by the expected recovery acquisition unit 115, and a progress acquisition unit. A difference with the completion time of each stage indicated by the progress information acquired by 116 is obtained. Then, the time calculation unit 112 recalculates the expected recovery time by correcting the initial expected recovery time based on the difference between the completion times of the respective stages. For example, the time calculation unit 112 may add the sum of the differences between the completion times of the respective stages to the initial expected recovery time, or prepare the coefficient corresponding to the difference between the completion times of the respective stages included in the expected recovery time. Time, travel time, and work time may be multiplied.

  In addition, when the progress acquisition unit 116 acquires the progress in each stage (for example, that the recovery operation is delayed or accelerated by X%), the time calculation unit 112 reflects the progress in the expected recovery time. May be.

  The accuracy specifying unit 113 specifies the accuracy of the expected recovery time based on the progress information acquired by the progress acquiring unit 116 when the time calculating unit 112 recalculates the expected recovery time. The accuracy specifying unit 113 stores the specified accuracy in the storage unit 13.

  In order to specify the accuracy, the accuracy specifying unit 113 specifies the accuracy so as to increase as the progress of recovery progresses. The accuracy specifying unit 113 may decrease the accuracy when the progress of the recovery is delayed from the schedule or when the work is stopped.

  Further, the progress acquisition unit 116 and the accuracy specifying unit 113 may specify the progress and accuracy based on a signal indicating whether or not a failure has occurred (for example, an alarm indicating a failure detected by an external system). In such a configuration, an alarm indicating a failure indicates an abnormality when a failure occurs, and indicates a normal state when no failure occurs. The progress acquisition unit 116 and the accuracy specifying unit 113 determine that the recovery progress is complete when the alarm indicating the failure returns from normal to normal and the alarm indicating the failure is normal for a predetermined time or more, The accuracy is specified as 100%. As a result, the management apparatus 1 can automatically determine the completion of the recovery and output a message to that effect to the user U1.

  The difference between the expected recovery time recalculated by the time calculation unit 112 (that is, the estimated recovery time after correction) and the expected recovery time calculated by the time calculation unit 112 (that is, the initial expected recovery time) is a predetermined time or more. In some cases, the output unit 114 outputs the corrected expected recovery time and accuracy to the user U1 (f). Since the management apparatus 1 notifies only when the difference in recovery expected time is large, the frequency of notification to the user U1 can be suppressed. Further, the output unit 114 may output the expected recovery time and accuracy after correction to the administrator U2 and the worker U3.

  The output unit 114 is a recovery expected time after correction on a display device (for example, a display unit included in the administrator terminal 2, the user terminal 3, and the worker terminal 4) accessible to the user U1, the administrator U2, or the worker U3. In addition, the accuracy may be displayed. The output unit 114 recovers after correction by sending an e-mail, a message, or the like to the administrator terminal 2, the user terminal 3, or the worker terminal 4 corresponding to the user U1, the administrator U2, or the worker U3. The expected time and accuracy may be notified. The output unit 114 may print the expected recovery time and accuracy after correction on paper using a printer. Further, the output unit 114 may output the corrected expected recovery time and accuracy by transmitting a facsimile to the telephone number corresponding to the user U1.

  FIG. 4B is a front view of the user terminal 3 displaying information from the management apparatus 1 according to the present embodiment. When the user terminal 3 receives information indicating the expected recovery time and accuracy after correction from the management device 1, the user terminal 3 displays the expected recovery time T2 and accuracy A after correction on the display unit according to the information. Thereby, the management apparatus 1 can notify the user U1 of a highly accurate recovery expected time with little deviation from the time when the recovery operation is finally completed. Moreover, the management apparatus 1 can inform the user U1 of the certainty of the recovery expected time by outputting the accuracy together with the recovery expected time to the user U1. Similarly, the manager terminal 2 and the worker terminal 4 may display the corrected expected recovery time T1 and the accuracy A.

  The output unit 114 may output the expected recovery time to the user U1 at a time interval associated with the user U1. In this case, the time interval is set in advance in the management apparatus 1 for each user U1. When the time interval associated with the user U1 has elapsed from the initial expected recovery time or the previous corrected recovery time, the output unit 114 sets the corrected recovery expected time for the user U1. Output. As a result, the management apparatus 1 outputs the expected recovery time at a low frequency for the user U1 who does not require frequent notification, and outputs the expected recovery time at a high frequency for the user U1 who requests frequent notification. can do.

  The output unit 114 may output the expected recovery time to the user U1 when the accuracy of the expected recovery time satisfies a predetermined condition. For example, the output unit 114 outputs the expected recovery time to the user U1 when the accuracy of the expected recovery time is 50% or more. Thereby, since the management apparatus 1 outputs the recovery expected time with sufficient accuracy, it is possible to suppress frequent correction of the recovery expected time.

  The output unit 114 may notify the worker U3 when the corrected recovery expected time is a predetermined time or more after the initial recovery expected time. In this case, when the expected recovery time after correction is a predetermined time (for example, 30 minutes) or more after the initial recovery expected time, the output unit 114 sets the initial recovery expected time and the expected recovery time after correction. Is transmitted to the worker terminal 4.

  FIG. 5 is a front view of the worker terminal 4 displaying information from the management device 1 according to the present embodiment. When the worker terminal 4 receives information indicating the initial recovery expected time and the corrected recovery expected time from the management apparatus 1, the worker terminal 4 displays the initial recovery expected time T1 and the corrected recovery expected on the display unit according to the information. The time T2 is displayed. As a result, the management device 1 can inform the worker U3 that the worker is behind the prospect of the original recovery, and can prompt the user to proceed with the recovery work early.

[Management method flowchart]
FIG. 6 is a diagram illustrating a flowchart of a management method executed by the management apparatus 1 according to the present embodiment. First, the status acquisition unit 111 acquires status information indicating a status related to the recovery work from the administrator terminal 2 (S11). The time calculation unit 112 calculates the expected recovery time based on the status related to the recovery work acquired by the status acquisition unit 111 (S12).

  The output unit 114 outputs the expected recovery time calculated by the time calculation unit 112 to the user U1 (S13). At this time, the output unit 114 outputs the accuracy calculated by the accuracy specifying unit 113 in addition to the expected recovery time. The output unit 114 may output the expected recovery time to the administrator U2 and the worker U3.

  The recovery expectation acquisition unit 115 reads out and acquires the initial recovery expected time from the storage unit 13, and the progress acquisition unit 116 acquires progress information indicating the progress of the recovery from the administrator terminal 2 or the worker terminal 4 ( S14). The time calculation unit 112 recalculates the expected recovery time based on the initial expected recovery time and the progress of the recovery (S15).

  When the difference between the expected recovery time recalculated by the time calculation unit 112 in step S15 and the initial expected recovery time calculated by the time calculation unit 112 in step S12 is a predetermined time or more (YES in S16), the output unit 114 outputs the corrected expected recovery time to the user U1 (S17). At this time, the output unit 114 outputs the accuracy calculated by the accuracy specifying unit 113 in addition to the expected recovery time after correction. The output unit 114 may output the expected recovery time to the administrator U2 and the worker U3.

  When the difference between the expected recovery time recalculated by the time calculation unit 112 in step S15 and the initial expected recovery time calculated by the time calculation unit 112 in step S12 is less than a predetermined time (NO in S16), the output unit 114 does not output the expected recovery time after correction.

  The management apparatus 1 repeats steps S14 to S17 when a predetermined end condition (for example, that the restoration work has been completed) is not satisfied (NO in S18). When the predetermined end condition is satisfied (YES in S18), the management device 1 ends the process.

  In the present embodiment, the time calculation unit 112 recalculates the recovery expected time by adding progress information to the initial recovery expected time calculated by itself, but progresses to the initial recovery expected time calculated by the external system. The recovery expected time may be recalculated by adding information.
