드론 활용 혈액 운송시스템의 효과 분석

Drones, which were developed for military activities such as surveillance and attack on behalf of people in dangerous areas, are used in various social areas such as broadcasting photography, leisure activities, surveillance activities, and lifesaving. In addition, the value of utilization of these drones is prominent in the field of emergency transportation such as medicines, relief supplies, and blood products, and research on this is actively being studied in related fields. In particular, the drone-utilized blood transportation system in the city, which faces traffic congestion problems, is drawing attention as an alternative method in that it can respond more quickly to urgent blood demand than conventional road transportation. Thus, this study proposes integer programming models for three transportation systems to compare and analyze them in terms of required cost and time. These systems are a conventional transport system and two transport systems that utilize drones at only the blood center, and at the blood center and drone depots. Drone depots are installed at some of hospitals to decrease transportation distance. This paper performs a case study on the Korean National Red Cross in Seoul city and conducts sensitivity analysis to draw operational implications from the development of drone technology and the number of drone depots.
