Supporting Effective Infrastructure Restoration Plans in the Event of a Disaster

Social Digital Twin technology makes it possible to efficiently create infrastructure recovery plans when a disaster occurs. Digital rehearsal allows for quick and appropriate response by simulating in advance where repairs will achieve the best results. This article introduces the restoration of water infrastructure.

Challenges

  • During disasters, people gather at disaster bases such as hospitals and shelters to seek safety. This increases the water demand in the areas where these disaster bases are located. Therefore, it is necessary to ensure that water can be supplied preferentially to these areas in case of water outage. Restoring water supply requires specialized construction, but the number of workers is limited. Various factors need to be considered, including minimizing waste due to water leakage, completing the work within a limited budget, and quickly restoring the lives of as many disaster victims as possible. Therefore, it is necessary to formulate a recovery plan in the most effective way.

Solutions

  • Digital twins are constructed in a digital space, representing the water pipes and their damage status, as well as the evacuation status to shelters. Impact indicators such as changes in water supply status due to pipe repairs and construction costs are calculated through digital rehearsal.
  • The recovery construction planner sets various repair proposals and compares the impact indicators obtained through digital rehearsal from multiple perspectives, selecting the best plan.

Strength

  • IThe combination of various simulators such as hydraulic simulators, flood simulators, and evacuation behavior simulators allows for a comprehensive evaluation of the impacts of various events such as water pipe damage. This makes it possible to formulate balanced plans. 【 Related patent application pending】

Advanced Applications

  • Water truck scheduling
    Identify areas where water supply is difficult and plan for the operation of water trucks to enable more evacuees to receive water.
  • Restoration of water supply to residential areas
    Design a recovery plan that prioritizes water supply to habitable homes so that evacuees can return to their normal lives quickly.
  • Regular water pipe renewal plan
    Prepare for disaster by figuring out which old water pipes will cause the most water problems if they break and planning to fix these critical pipes first.
  • Comprehensive Infrastructure Recovery
    This can also be applied to other infrastructure networks such as power, gas, and communication.In addition, support for recovery plans coordinated among infrastructures becomes possible.
