TOOL FOR BUSINESS RESILIENCE TO DISASTER

1 . A computer-implemented method comprising:

calculating, by one or more processors, component fragility functions for components of a facility that are vulnerable to damage after a disaster;

calculating, by the one or more processors, component recovery functions for the components of the facility, the component recovery functions indicating a probability of recovery after a disaster over time;

calculating, by the one or more processors, a facility fragility function and a facility recovery function based on the component fragility functions and the component recovery functions;

determining, by the one or more processors, a downtime for the facility for a given intensity associated with the disaster; and

causing, by the one or more processors, presentation of the downtime for the facility on a user interface (UI).

2 . The method as recited in claim 1 , wherein the UI provides a first option for selecting a disaster from a group consisting of earthquake, hurricane, and flood, and a second option for selecting a scenario for the disaster.

3 . The method as recited in claim 1 , wherein the components include infrastructure objects and employees affected by the disaster.

4 . The method as recited in claim 1 , wherein determining the downtime includes calculating an impact of the disaster on production facilities, demand, supply, and employees.

5 . The method as recited in claim 1 , wherein the components include roads, wherein determining the downtime further comprises:

determining downtime for road segments and bridges within a predetermined distance from the facility.

6 . The method as recited in claim 1 , wherein the facility is a shipping port and the components comprise a wharf and a crane.

7 . The method as recited in claim 6 , further comprising:

calculating the facility recovery function for the shipping port for a plurality of values of earthquake shaking.

8 . The method as recited in claim 1 , further comprising:

determining an average annual downtime for the facility for a predefined planning period based on a plurality of return periods for the disaster.

9 . The method as recited in claim 1 , wherein an average downtime for the disaster is based on an area above a recovery curve associated with the facility recovery function.

10 . The method as recited in claim 1 , wherein the UI includes an option for presenting related facilities that affect recovery time for the facility when the disaster occurs.

11 . A system comprising:

a memory comprising instructions; and

one or more computer processors, wherein the instructions, when executed by the one or more computer processors, cause the system to perform operations comprising:

calculating component fragility functions for components of a facility that are vulnerable to damage after a disaster;

calculating component recovery functions for the components of the facility, the component recovery functions indicating a probability of recovery after a disaster over time;

calculating a facility fragility function and a facility recovery function based on the component fragility functions and the component recovery functions;

determining a downtime for the facility for a given intensity associated with the disaster; and

causing presentation of the downtime for the facility on a user interface (UI).

12 . The system as recited in claim 11 , wherein the UI provides a first option for selecting a disaster from a group consisting of earthquake, hurricane, and flood, and a second option for selecting a scenario for the disaster.

13 . The system as recited in claim 11 , wherein the components include infrastructure objects and employees affected by the disaster.

14 . The system as recited in claim 11 , wherein determining the downtime includes calculating an impact of the disaster on production facilities, demand, supply, and employees.

15 . The system as recited in claim 11 , wherein the components include roads, wherein determining the downtime further comprises:

determining downtime for road segments and bridges within a predetermined distance from the facility.

16 . A tangible machine-readable storage medium including instructions that, when executed by a machine, cause the machine to perform operations comprising:

calculating component fragility functions for components of a facility that are vulnerable to damage after a disaster;

calculating component recovery functions for the components of the facility, the component recovery functions indicating a probability of recovery after a disaster over time;

calculating a facility fragility function and a facility recovery function based on the component fragility functions and the component recovery functions;

determining a downtime for the facility for a given intensity associated with the disaster; and

causing presentation of the downtime for the facility on a user interface (UI).

17 . The tangible machine-readable storage medium as recited in claim 16 , wherein the UI provides a first option for selecting a disaster from a group consisting of earthquake, hurricane, and flood, and a second option for selecting a scenario for the disaster.

18 . The tangible machine-readable storage medium as recited in claim 16 , wherein the components include infrastructure objects and employees affected by the disaster.

19 . The tangible machine-readable storage medium as recited in claim 16 , wherein determining the downtime includes calculating an impact of the disaster on production facilities, demand, supply, and employees.

20 . The tangible machine-readable storage medium as recited in claim 16 , wherein the components include roads, wherein determining the downtime further comprises:

determining downtime for road segments and bridges within a predetermined distance from the facility.
