1. A method for assessment of an oil and gas flow network, the method comprising:
gathering historical data and/or live data relating to the status of multiple control points at different branches within the flow network and to one or more flow parameter(s) in one or more flow path(s) of the flow network in which flows of more than one of the different branches have been combined;
processing the historical and/or live data relating to the status of the multiple control points and to the one or more flow parameter(s) to identify adjustments that have been made in one or more of the control point(s) that result in changes to one or more of the flow parameter(s);
determining relationships between the status of the control point(s) and the flow parameter(s) by generating one or more local model(s) for the system based on the status of the control point(s) and the flow parameter(s) before and after the adjustments that are identified from the historical and/or live data; and
using said relationships in the assessment of factors relating to performance of the flow network.
