The interest on the irrigation pipe network systems have been increased. The irrigation pipe network is not affected by the topography and possible to enough supply. Therefore, the network system is applied in the large scale agricultural complex. In this study, a model to optimize pipe diameters was developed to supply enough irrigation water efficiently in the branch type pipe network. The developed model was applied in a agricultural complex with several water demands, hydraulic head in the starting nodes, hydraulic gradients in the different types of the irrigation sector. The optimized pipe diameter was proposed for the standardization of the design. The decision variable of the conventional method was the length of the pipes to linearize the optimization system. In the method, more than two sizes of the diameter were proposed, which was not realistic. Therefore, in this study, the new optimization method was suggested using binary integer programming whose decision variables are the binary number to represent that the pipe with the proposed diameter was installed or not. The design standard was proposed using the simulation results from the sensitivity analysis. The result is used to find the optimal pipe diameter without the model simulation if the type of sector and water demand are known, which is very economic design for the future agriculture area.
