Optimization of Tree Pipe Networks Layout and Size, Using Particle Swarm Optimization

摘要

A commonly used design method for irrigation pipe network (IPN) layout and size often involves trial and error approach. This makes it difficult to minimize capital investment and energy cost. Objective of this study was to optimize simultaneously size and layout of the irrigation pipe networks using particle swarm optimization (PSO) technique. This technique was linked to the MATLAB software to reduce the pipeline investment cost in irrigation projects. The Pipe layout and size optimization model for a tree irrigation pipe network are therefore, presented in this paper. The performance of PSO technique was tested and results were compared with non-optimized (Step-by-step) and genetic algorithm optimization methods. The proposed PSO technique with an increase in the search space showed a quick response in the size of the swarm and the initial swarm compared to the non-optimized (Step-by-step) design method and genetic algorithm.
