Abstract: A system and method for designing an electricity distribution network in a geographic area includes receiving design inputs that include data indicative of locations of one or more substations, a location of at least one zone substation, how much power is required by the substations, a supply capacity of the zone substation, and data indicative of a maximum allowed number of outgoing feeders that can be supported by the zone substation; receiving or accessing architecture rules dictating minimum requirements of the electricity distribution network; electronically generating design outputs by determining a plurality of paths using the design inputs, the architecture rules and a linear optimisation function subject to linear and integer constraints, such that a total length of the paths is minimized, wherein the design outputs include the plurality of paths; and electronically outputting the design outputs.

Abstract: A computer-implemented method and system for designing a fiber optic network for a plurality of premises in a geographic area that has existing infrastructure. The system includes an input module arranged to electronically receive design outputs comprising geographic locations of nodes in the fiber optic network and arcs extending between the nodes, relative to at least elements of existing infrastructure used as geographic locations for the nodes and the arcs, the elements of the existing infrastructure being associated with characterizing data that characterizes the elements of existing infrastructure; the input module is further arranged to electronically receive validation data corresponding to the elements of the existing infrastructure, the validation data being indicative of validity of the characterizing data. The system includes an optimizer arranged to electronically generate new design outputs by optimizing geographic locations of the nodes and the arcs in the fiber optic network.
