The Inverse Calculation of Roughness Coefficient in Village and County Circular Pipe Network based on Stochastic Particle Swarm Optimization

摘要

As time's going on, county pipes 'aging problem is even serious, and water providing capability is coming down. Stochastic Particle Swarm Optimization is an improvement of the standard PSO, compared with which, it can be guaranteed to converge to the global optimization solution with probability one in theory, and speed up the convergence. By using this method in the county pipe network inspection system, its running conditions will be got generally and betimes, accordingly, the control of water source is regulated for supplying the industry and citizen safely.
