An Optimization of the Submain and the Lateral Diameter in Microirrigation Subunit Based on the Genetic Algorithms
Based on a genetic algorithm, an optimization method is established for designing the submain and lateral with the same diameter in the micro-irrigation subunit on the sloping fields. This optimization method considers the cost of the subunit to the minimum as the goal, the irrigation uniformity and average discharge of emitter as the constraints, the submain diameter, lateral diameter, emitter number on the left side of lateral and orifice pressure at the end of submain as the decision variable. Under such condition that this method meets the design discharge of emitter and irrigation uniformity, it not only optimizes the diameter of the submain and lateral, determines inlet pressure of the subunit and the optimal submain position, but also calculates the pressure and discharge of each orifice on the submain and lateral. The simulation results show that the optimization method employed in the paper has a good solution efficiency, accuracy and reliability. If only the known desigh conditions are inputted into the computer, the optimization result will be figured out by itself, which has both the universal and the practical value.
