民航事故率高，医疗资源盘点在机场应急管理中显得尤为重要。同时，医疗产品通常具有时效性，使用寿命短。此外，我们发现最优的医疗资源库存取决于多种因素，如不同的风险偏好，材料的保质期等。因此，它在现实生活环境中变得非常复杂。针对这种情况，构建了机场应急准备医疗资源库存决策模型。我们的模型同时考虑了不确定性需求、随机发生时间和不同的风险偏好。为了解决这一问题，提出了一种新的编程方法。最后，给出了一个数值算例来说明所提出的方法。结果表明，在考虑机场不同风险偏好的情况下，该方法可以有效地确定需求不确定、随机发生时间的应急准备中最优医疗资源库存。
With the high accident rate of civil aviation, medical resource inventory becomes more important for emergency management at the airport. Meanwhile, medical products usually are time-sensitive and short lifetime. Moreover, we find that the optimal medical resource inventory depends on multiple factors such as different risk preferences, the material shelf life and so on. Thus, it becomes very complex in a real-life environment. According to this situation, we construct medical resource inventory decision model for emergency preparation at the airport. Our model is formulated in such a way as to simultaneously consider uncertain demand, stochastic occurrence time and different risk preferences. For solving this problem, a new programming is developed. Finally, a numerical example is presented to illustrate the proposed method. The results show that it is effective for determining the optimal medical resource inventory for emergency preparation with uncertain demand and stochastic occurrence time under considering different risk preferences at the airport.
