摘　　要：应急设施选址问题是应急管理中的重要问题,设施的长期战略性地位,促使决策者在进行选址决策时关注多种目标.在一定的经济投入条件下,本文首先提出了决策者制定设施选址方案时的目标原则,构建以时效性、均衡性和鲁棒性为核心的评价体系,进而建立了应急设施选址的多目标优化模型,用覆盖为目标的救援总时间反映时效性,最大救援半径反映均衡性,以及设施损毁情景下额外增加的救援变更时间反映鲁棒性,用三个目标函数组成的三元组刻画选址决策的目标向量,理想点是一个三元向量,每一个分量值表示只以这个分量目标函数求解得到的最优值,提出了基于理想点的目标扰动最小化模型,并采用遗传算法设计求解方法,通过算例分析了模型和算法的有效性,说明本文提出的模型与算法在解决应急设施选址决策方面具有一定的应用价值.Abstract Emergency facility location is an important problem in emergency management. Multiple objectives need to be considered since facilities have a long-term significant position. Limited by budget, objective decision system for facility location is presented firstly in this paper which includes time-effectiveness, equitableness and robustness. Then, based on total emergency response time, maximum response time radius and additional response changing time because of facility failure scenario, a multi-objective optimization model is formulated. In order to solve this model, an objectives disturbance minimization model is presented based on ideal point. Since this model is NP-hard, an efficient algorithm is designed based on genetic algorithm. Experiment results show it is useful for decision of emergency facility location both the model and algorithm proposed in this paper.
