Disaster Resilience and Recovery Plans

Simulating human and societal behavior in digital space to support the rapid and efficient planning of infrastructure recovery.

Challenges in Infrastructure Restoration During Disasters

In the event of a large-scale disaster, it is an urgent issue to formulate a rapid and effective infrastructure recovery plan. In particular, the restoration of water infrastructure for important facilities, such as hospitals and evacuation centers, is urgent.
In practice, however, it is exceedingly difficult to formulate an optimal recovery plan based on the various circumstances of an emergency.

Solution

Digital Rehearsal recreates water pipe networks and evacuation situations in the digital space. By integrating simulators from different fields such as water pipes and traffic with human behavior models, it enables multifaceted analysis and the development of optimal recovery plans. This minimizes disruption to residents' lives and promotes the rapid resumption of economic activity. It also supports infrastructure renewal planning during normal operations.

Rapid recovery planning	Digital Rehearsal, which simulates the behavior of people and society in the digital space, enables the development of an optimal recovery plan in a short time.
Reduction of human damage and economic loss	Effective recovery planning minimizes disaster damage and promotes early recovery of social functions.
Applicability to diverse infrastructures	It can be applied not only to water supply but also to various infrastructures such as electric power, gas, and communication.
Variety of operating environments	All you need is a browser, and you do not need any technical knowledge to operate it. It can also run on a standalone basis, so it can be used even if the network is unavailable in the event of a disaster.
Usability in normal time	It can also be used for infrastructure management during normal times, such as planning to replace aging water pipes.

Technical Overview

Target Industry/Users

Organizations involved in infrastructure restoration, such as government agencies, municipalities, public utilities, telecommunication providers, and energy providers, among others, are assumed. The organizations that require rapid infrastructure recovery from a major disaster are targeted.

Challenges in Target Industry and Operations

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.

Technical Challenges

Formulation of an effective recovery plan according to the limited workforce, construction budget and actual evacuation situation.

Solutions

Water pipes are constructed as digital twins in the digital space, representing their damage status and 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, and finally selects the best one.

Fujitsu's Technological Advantage

The integration of various simulators, such as hydraulic simulators, flood simulators, and evacuation behavior simulators, allows for a comprehensive assessment of the impacts of events like water pipe damage. This approach enables the formulation of well-balanced plans by considering multiple perspectives. 【 Related patent application pending】

Effective disaster resilience and recovery strategies deliver value such as reducing the human suffering and economic losses of disasters, quickly restoring social functions, and improving business continuity. Rapid and efficient recovery will minimize the impact on society and facilitate the early resumption of economic activity.

A Proof of Concept (PoC) can also be conducted.

Case Studies

Water truck scheduling
It is possible to identify areas where water supply is difficult and plan the operation of water trucks to enable more evacuees to receive water.
Restoration of water supply to residential areas
It is possible to design a recovery plan that prioritizes water supply to habitable homes, enabling evacuees to return to their normal lives more quickly.
Regular water pipe renewal plan
It is possible to prepare for disaster by identifying old water pipes most likely to cause water problems if they break and planning to prioritize their repair.
Comprehensive Infrastructure Recovery
This approach can also be applied to other infrastructure networks such as power, gas, and communication. Furthermore, coordinated infrastructure recovery plans can be supported.
