【Abstract】 This paper set up a two-level optimal design model of gravity tree pipe network and the nonlinear programming model was solved quickly by the method of artificial neural networks.The two-level optimal design model adopting the technique of artificial neural networks is superior to the single nonlinear programming model and linear programming model in the application scopes, speed of solving and the capability of acquiring optimal solution. It’s a new way to realizing the global optimal design of tree pipe networks.更多还原
