Seismic Topology Optimization Algorithms for Water Distribution Networks based on Automatic Generation Strategy

Abstract:

Taking water distribution network’s annual reduced cost as optimization object and seismic reliability as optimization restriction, a network topology optimization model is established. Then, an automatic generation strategy based on the existed road information is proposed. Combining with ring network generation method and automatic generation strategy, three approaches, a genetic algorithm, a simulated annealing genetic algorithm and a particle swarm algorithm, are employed to solve the seismic optimization model. Two networks are optimized using three algorithms and a comparative study is performed. The comparison indicates that the simulated annealing genetic algorithm performs the best.
