摘　　要：为提升综合救灾能力,利用情景建模法构建不同的灾害情景;在应急资源有限的约束条件下,以最大化应急救援社会价值为目标,并兼顾分配公平,建立应急资源精益配置模型,主要包括储备库选址与规模设置、不同灾害情景下的物资分配方案制定;利用改进差分进化算法求解模型,并通过数值案例对算法进行验证。结果表明：所建模型有助于实现有限应急资源的社会价值最大化,用改进的差分进化算法能够求得模型的最优解,为决策提供依据。In order to improve the ability to cope with sudden natural disasters,and improve the efficiency of emergency response,scenario modeling method was used to construct different disaster scenarios,and a lean deploying model of emergency resources was built which was aimed at maximizing the social value of emergency rescue,considering distribution fairness and resources limitation. Main decisions included location and scale of facilities,allocation of emergency supplies in different scenarios. An improved differential evolution algorithm was worked out to solve the model and the algorithm was verified by a numerical example. The results show that the model can achieve the goal that maximizing social value of limited emergency resources,and the improved differential evolution algorithm can be used to obtain the optimal solution of the model and provide a basis for decision making.
