Abstract:Optimization design of annular pipe network plays an important role in decreasing the cost of water-supply engineering. A new idea of dimensionless processing of variables was introduced into the modelling process of minimizing the objective function w0 (converted value of annual cost) with constraint of hydraulic condition and then this nonlionear programming model obtained was solved by using the algorithm of particle swarm otimization. It was shown by an illustrative computation that the algorithm and its model were very valid for optimization of annular pipe network design. further, the time complexity was decreased by about 26.89%, embodying sufficiently stronger optimizing ability of particle swarm optimization algrithm.
Keywords:particle swarm optimization algorithm  annular pipe network  dimensionless processing optimization design
