突发事件下的医院应急资源冗余配置优化模型

突发事件发生前，医院需要保持一定的应急资源冗余量。针对突发事件下医院应急资源冗余的配置优化问题，首先，基于效用理论，通过分析医院应急资源冗余的效用体现来对应急资源冗余进行定义和分类，确定了符合边际规律的效用函数；其次，建立了总效用最大化的医院应急资源冗余配置模型，并给出应急资源储存量的上限及应急合理度的下限作为模型的约束条件；最后，把粒子群算法和序列二次规划法相结合进行寻优求解。通过案例分析，得出了医院四种应急资源冗余的优化方案，总结出了医院的应急水平对医院应急资源冗余的需求程度。研究表明，应急资源冗余配置优化模型能够帮助医院在突发事件下很好地进行应急救援，提高医院应急资源的利用效率。

Optimization model of hospital emergency resource redundancy configuration under emergencies

Before an emergency occurs， the hospitals need to maintain a certain amount of emergency resource redundancy. Aiming at the problem of configuration optimization of hospital emergency resource redundancy under emergencies， firstly， based on the utility theory， by analyzing the utility performance of the hospital emergency resource redundancy， the emergency resource redundancy was defined and classified， and the utility function conforming to the marginal law was determined. Secondly， the redundancy configuration model of hospital emergency resources with maximal total utility was established， and the upper limit of emergency resource storage and the lower limit of emergency rationality were given as the constraints of the model. Finally， the combination of particle swarm optimization and sequential quadratic programming method was used to solve the model. Through case analysis， four optimization schemes for the emergency resource redundancy of the hospital were obtained， and the demand degree of the hospital emergency level to the hospital emergency resource redundancy was summarized. The research shows that with the emergency resource redundancy configuration optimization model， the emergency rescue of hospitals under emergencies can be carried out well， and the utilization efficiency of hospital emergency resources can be improved.
