Abstract: In order to optimize the locations of emergency resource stations for flood prevention along highway net-work,a multi-objective optimization layout model is developed in the study with a focus on the arrival time of resources, construction cost of stations and functions of highways.A particle swarm optimization (PSO)algorithm is used to opti-mize the model.The optimizing layout method for emergency resource stations for flood prevention along highway net-work is proposed.The results of applying the optimization model to highway network in Beijing indicate that the solutions from the PSO algorithm are practical and meet the requirements of emergency responses. -
