摘　　要：为提高库区水域应急救助设施选址决策的科学性,在深入分析应急救助设施最优选址问题的基础上,引入应急需求点的安全风险权重系数,以应急救助点覆盖半径为约束条件,建立以公平性、时效性和可靠性为核心的应急救助设施选址多目标优化模型;利用多目标粒子群优化算法（MOPSO）进行模型求解,得到Pareto最优解集,运用改进的逼近理想解排序算法（TOPSIS）在Pareto最优解集中权衡筛选出最佳折衷选址方案;将所建模型应用于某库区水上应急救助设施选址问题。结果表明：模型的非劣解能够充分反映选址实例中的公平性、时效性和可靠性间的悖反关系;用MOPSO和TOPSIS算法,能有效求得选址多目标优化模型的最优折衷解。In order to make scientific decisions on emergency rescue facility location of the reservoir water,safety risk weight coefficient was introduced by analyzing the water emergency and rescue facilities optimal location problem thoroughly. A multi-objective optimization location model of emergency rescue facilities was built with fairness,timeliness and reliability as the objective,and the emergency coverage radius was taken as the constraint condition. The MOPSO algorithm was introduced to solve the Pareto optimal solution sets,and the compromise position was an effective tradeoff solution based on the improved TOPSIS algorithm. The model was used to solve a water emergency rescue facilities location problem in a certain reservoir area. The results show that the non-inferior solution fully reflects the trade-off relationship between the fairness,timeliness and reliability in this case,and that the optimal compromise solution of the multi-objective optimization location model can be achieved with the MOPSO and TOPSIS algorithms.
