Furthermore, in case 23, the recovery plan creation unit 12 can detect a failure in the HEMS by comparing routes 1 to 3. Further, it can be determined that no failure has occurred in the upper network 40.
  • step S434 since the degree of certainty is low, the recovery plan creation unit 12 creates a rough recovery plan. For example, the recovery plan creation unit 12 omits the creation of a detailed route as in step S433, and creates an approximate route approximated by the maximum value.
  • the recovery plan created as described above is output to the system administrator or worker terminal 50 via the UI section 15. As a result, workers can perform recovery work according to the recovery plan. This concludes the joint of FIG. 18 and returns to the explanation of FIG. 6.
  • step S44 the recovery plan creation unit 12 notifies the data management unit 13 of a write request for the created recovery plan.
  • step S36 the data storage unit 134 of the data management unit 13 stores the recovery plan in the storage unit 11 in response to the write request.
  • Embodiment 1 a recovery plan for disaster-related failures is created, but the present invention can also be provided to support so-called normal operations.
  • the second embodiment support for operations during normal times is targeted.
  • the configuration of the second embodiment is similar to that of the first embodiment, but differs in that the power grid management section 14 is used. Therefore, at least one of the recovery plan creation unit 12 and the power network management unit 14 in FIG. 1 may be omitted, or one of them may implement the function of the other.
  • step S42 in FIG. 6 the process up to step S42 in FIG. 6 is executed in the same manner as in the first embodiment. Further, in step S43, the power network management unit 14 creates a maintenance plan for maintenance as in the first embodiment. Then, from step S44 onwards, the same processing as in the first embodiment is executed. According to the second embodiment described above, more appropriate operational management such as facility maintenance can be realized. Note that it may be configured to create both the recovery plan of the first embodiment and the normal maintenance plan of the second embodiment. According to the second embodiment, a so-called normal maintenance plan can be realized more in accordance with the actual situation.
  • Embodiment 3 is an example in which, in addition to the creation of a recovery plan function in Embodiment 1, an application service using sensor data 111 and its reliability is executed as an example of a business.
  • Application services include monitoring services and home delivery services.
  • the degree of certainty is used to determine whether the consumer is at home or the like, and to provide an appropriate service. The contents will be explained below.
  • FIG. 22 is a diagram for explaining an overview of the processing of the service provision support device 100 in the third embodiment.
  • This service provision support device 100 has a service support section added to the power grid restoration plan support device 10 of the first and second embodiments.
  • patrol routes for monitoring services and home delivery services are created. That is, the data rehabilitation unit 133 performs context management on the sensor data 111 such as the utility pole sensor data 517, and identifies the consumer's at-home data. At this time, the data rehabilitation unit 133 calculates the degree of certainty that the person is at home as the degree of certainty. Then, the service support unit uses these to create a tour route. At this time, it is desirable to follow the processing flow shown in FIG.
  • the recovery plan and patrol plan be output via an API (Application Programming Interface).
  • API Application Programming Interface
  • the creation and output of the recovery plan may be omitted, and the process may be limited to service support.
