论文摘要
这项研究的重点是评估无人机在低收入和低收入国家偏远地区提供小儿疫苗的使用。由于道路网络不足，并且很长的运输距离，因此在这些地区提供疫苗是具有挑战性的，因此很难在运输过程中保持冷链完整性。我们提出了一个混合整数线性程序，以确定无人机轮毂的位置以促进疫苗的输送。该模型考虑了无人机的操作属性，供应链中的疫苗浪费，冷藏和运输能力。我们使用尼日尔的数据开发了一个案例研究，以确定无人机交付在改善尼日尔疫苗可用性方面的影响。我们的数值分析表明，疫苗的可用性增加了0.71至2.21。这些改进取决于可用的预算，以建造无人机枢纽和购买无人机，以及研究区域的人口密度。
The focus of this research is to evaluate the use of drones for the delivery of pediatric vaccines in remote areas of low income and low and middle income countries. Delivering vaccines in these regions is challenging because of the inadequate road networks, and long transportation distances that make it difficult to maintain the cold chain integrity during transportation. We propose a mixed integer linear program to determine the location of drone hubs to facilitate the delivery of vaccines. The model considers the operational attributes of drones, vaccine wastage in the supply chain, cold storage and transportation capacities. We develop a case study using data from Niger to determine the impact of drone deliveries in improving vaccine availability in Niger. Our numerical analysis show an 0.71 to 2.21 increase in vaccine availability. These improvements depend on the available budget to build drone hubs and purchase drones, and the population density in the region of study.
