Abstract
A method for analyzing survivability of an infrastructure link includes determining an optimal path arrangement of the infrastructure link between two geographic locations; and determining a risk index associated with the determined optimal path arrangement based on one or more quantified cost factors and one or more quantified risk factors associated with the determined optimal path arrangement. The risk index represents a survivability of the infrastructure link.

A method for designing and constructing a sub-marine cable, comprising:
- determining, using one or more processors, a laying path of the sub-marine cable between two geographic locations, including:
- modeling a geographic terrain containing the two geographic locations, including modelling the geographic terrain into a grid with multiple grid points in which each point of the model is denoted by a 3D coordinate including altitude of the geographic terrain;
- optimizing, using the one or more processors, an arrangement cost and a repair rate for the laying path based on the modelled geographic terrain, an arrangement cost model, and a repair rate model;
- determining, using the one or more processors and based on the optimization, a set of Pareto optimal solutions for generating an approximate Pareto front;
- and
- determining, using the one or more processors, the laying path based on the approximate Pareto front;
- determining, using the one or more processors, whether a disaster that affects the determined laying path has occurred;
- in response to determining that a disaster has occurred, using the one or more processors to broadcast information related to the occurrence of the disaster;
- in response to the broadcasting of the information, receiving at the one or more processors, input of one or more weightings to be applied to one or more quantified cost factors and one or more quantified risk factors associated with the determined laying path;
- applying, using the one or more processors, the one or more weightings to the one or more quantified cost factors and one or more quantified risk factors to determine a weighted sum of the one or more quantified cost factors and the one or more risk factors;
- determining, using the one or more processors, a plurality of respective local risk indices, each respective local risk index of the plurality of respective local risk indices being associated with a respective portion of a plurality of portions of the determined laying path, the respective local risk index of at least two portions of the plurality of portions being determined based on different cost and risk factors, and a sum or integration of the plurality of respective local risk indices providing a risk index that represents a survivability of the sub-marine cable affected by the disaster;
- and
- constructing the sub-marine cable based on the determined laying path and the plurality of respective local risk indices, using one or more higher levels of cable protection and/or shielding to construct portions of the plurality of portions having higher local risk indices.
