A decision management system simulates a communications network service deployment using business and technology changeable parameters a base case model, a network cost model and a bandwidth model. The 5 simulations may be performed for different sets of changeable parameters to generate multiple candidate solutions. These solutions are analyzed to identify a solution for deploying the communications network service. 0 105/09,c. 17894.spcification as filed. I -may-093 F-Z z0 < H 00 wj uj w z (Du 0 z--u 00 Qo~ U
