1. A method for analyzing a network, comprising: receiving information associated with the network; automatically constructing a network representation using the information, wherein the network representation is a logically simulated network, wherein the automatically constructing comprises: assigning a highest priority to one of a plurality of construction factors, wherein the plurality of construction factors comprises a reliability target, a call volume, a cost target, a capacity target, a subscriber rate, and a call model, wherein the highest priority of the one of the plurality of construction factors is a higher priority over any other construction factors; and constructing the network representation in accordance with the highest priority of the one of the plurality of construction factors; and performing a network performance test, wherein the network performance test is performed using a portion of the network representation.
