Optimized Designing of Irrigation Networks Using Meta-heuristic DMPSO Algorithm

Irrigation networks are the infrastructures in which researchers have shown an increased interest due to the huge costs of the construction and maintenance. In this sense, minimizing the costs of irrigation networks is the objective of many researchers in such a way that the conditions of minimum pressure and maximum speed are satisfied. In this study, DMPSO algorithm based on modification and mutation in PSO algorithm is proposed. Applying the proposed DMPSO algorithm, the optimum solution for the irrigation network of “Esmaeelabad” including 16 pipes and 17 nodes is explored deeply. The numeric results of hydraulic analysis were evaluated by creating a dynamic connection between MATLAB and EPANET. Using DMPSO meta-heuristic algorithm, the obtained optimum solution for the irrigation network of Esmaeelabad was compared with experimental method. It was shown that meta-heuristic algorithm reduced the total cost for 10.68% related to the experimental method and, furthermore, this proposed method is simple but more relatively accurate.
