A method for determining optimal path arrangements for an infrastructure link between two geographic locations. The method includes modelling a geographic terrain containing the two geographic locations; optimizing an arrangement cost and a repair rate for two or more potential paths based on the modelled geographic terrain, an arrangement cost model, and a repair rate model, taking into account at least two design levels; and determining the optimal path arrangements each including multiple path portions and respective design levels associated with the path portions based on the optimization.

System and method for determining optimal path arrangements for an infrastructure link with two or more design levels

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.

System and method for analyzing survivability of an infrastructure link

A method for determining optimal path arrangements for an infrastructure link between two geographic locations, in particular, in uneven terrain. The method includes modelling a geographic terrain containing the two geographic locations; optimizing an arrangement cost and a repair rate for two or more potential paths based on the modelled geographic terrain, an arrangement cost model, and a repair rate model, taking into account at least two design levels, wherein the arrangement cost model incorporates direction-dependent factor and direction-independent factor associated with the path arrangements; and determining the optimal path arrangements each including multiple path portions and respective design levels associated with the path portions based on the optimization.

System and method for determining optimal path arrangements for an infrastructure link with terrain slope consideration

A computer-implemented method and system for determining a path arrangement of an infrastructure link. The method includes receiving one or more inputs each indicative of a constraint; and processing the one or more inputs and a set of data based on a path arrangement determination model. The set of data includes data representing one or more factors affecting the path arrangement. The method also includes determining, based on the processing, the path arrangement of the infrastructure link.

Infrastructure link path arrangement determination method and system

A method for determining an optimal laying arrangement of a new infrastructure link for connection from a new site to an existing infrastructure network includes modeling a terrain of a region around and at the new site and the existing infrastructure network near the new site; modeling each factor affecting the laying arrangement as a respective cost function; applying a respective weighting to each of the cost function to determine a life-cycle cost function; and determining, based on the determined life-cycle cost function, an optimized laying arrangement with minimal life-cycle cost from the new site to a connection point in the existing infrastructure network.
