Abstract: 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.

Abstract: 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.

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.

Abstract: The present invention provides a cable planning method based a fast marching method applied with simulated annealing (FMM/SA) algorithm. In the FMM/SA algorithm-based cable planning method, the FMM used to obtain the optimal submarine cable path with the lowest life-cycle cost, and the SA algorithm is used to continuously adjust the weight of each design consideration with the aim to achieve an optimal cable path that is as close as possible to a real-life cable path which has a history of cost-effectiveness and resilience. The set of weights contributed to the optimal cable path is then used as an optimal set of weights of design considerations for cable path planning. The FMM/SA algorithm-based cable planning method can provide a computationally effective approach which has lower computation costs and better performance in generating cable paths with optimal life-cycle cost and reliability.

Abstract: 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.

Abstract: 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.
