防汛应急保障资源站点优化布设方法研究∗

摘要

针对高速公路网防汛应急保障资源站点的最优化布设问题，从资源到达时间、站点建设成本、线路的功能定位出发，构建更符合法规要求和应急抢险实际需要的防汛应急保障资源站点的多目标最优化布设模型，并采用粒子群优化算法进行了模型的求解，提出了高速公路网防汛应急保障资源站点的优化布设方法。对北京市高速公路网防汛应急保障资源站点的优化布设结果表明，基于粒子群算法的高速公路网应急保障资源站点多目标优化布设方法能够满足应急抢险实际工作所需，具有较好的实际应用效果。%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.
