Research On Optimal System Of The Sewage Pipeline Based On Particle Swarm Algorithm

In the paper, the engineering background is sewage pipeline system project in Suzhou city. Pipeline system planning usually involves pipeline layout optimization and pipeline hydraulic parameter optimization. In general, there is a large investment and a long repayment period for sewage pipeline system. This will need to offer a more advanced and reliable design method (algorithm) or design platform to optimize the design of the sewers, make an optimized design according to the sewage pipe network, and seek the economic and reasonable design scheme, which will have extremely vital significance.An improved particle swarm optimization (PSO) algorithm is proposed and applied to sewage pipeline optimization so that the cost of the whole system for sewage pipeline is reduced. The main research results are as follows:(1) Discrete particle swarm algorithm will be applied to optimize the layout of the sewers. First, layout optimization mathematical model for a sewage pipe network is established, and then discrete particle swarm algorithm is applied to the model. Compared with genetic algorithm (GA), the experimental results show that discrete particle swarm algorithm has better performance.(2) Based on the differential disturbance factor particle swarm optimization, an improved multi-swarm particle swarm optimization algorithm (MSPSO) is presented to solve the problem of the slow convergence and diversity issues for loss.(3) A particle swarm optimization algorithm based on improved multi-swarm is applied to hydraulic parameters optimized design of the sewers. Under the background of sewage system for the pipeline project in Suzhou city, corresponding simplified mathematical model is established. The algorithm is applied to the sewers hydraulic parameters optimization, and the experimental results show that the algorithm is feasible and efficient.(4) The sewage pipeline optimal system is developed. Based on an improved multi-swarm PSO (MSPSO) method, the sewage optimal system is developed relying on Shzhou Unimap Software co. Ltd., which is seamless with the company's existing pipeline system. The system has been applied to optimization of the sewers so that the whole pipeline system cost is significantly lower than in the past.(5) Sewage pipeline measured system is developed. In order to achieve result data management in the way of project, according to the characteristics of different pipelines, achieve rapid data editing for point and line etc, sewage pipeline measured system is developed using Microstation Development Language (MDL) in the Microstation environment. The system has been applied to pipeline product of Pipeline Bureau at present.This research and proposed method not only benefit the development of techniques in related fields theoretically, but also it can be applied to practical application. Moreover, it makes reference for further research in the Sewage pipeline Optimization field.
