In the construction of natural gas pipe network, due to consideration of two important factors of technology and economy, so we need to make the best choice among these feasible schemes. In this paper, the principle of parameters optimization of natural gas pipeline network was introduced. The objective function for minimizing the investment and running cost was established, then it was solved under the premise to meet the pipeline strength, stability, gas flow and node flow conditions. The complex algorithm, penalty function method and genetic algorithm were introduced, and these algorithms were combined to simplify the calculation of the optimization mathematical model.
