국내 혈액 센터에서의 혈액 적정 재고량 유지를 고려한 이동식 헌혈 시설의 운영 최적화 사례 연구

The inventory management in the blood center is still challenging due to the uncertainties related to blood supply and perishability of the blood products. In particular, the uncertainty originated from blood supply is hard to mitigate because blood can only be obtained from voluntary donation from blood donors. To increase blood donation, mobile blood donation facilities such as blood donation buses have widely been used all over the world since they can attract potential blood donors. However, the systematic scheduling of such mobile donation facilities is not yet adequately applied in practice. In this paper, we propose a mixed integer programming formulation that determines optimal schedules of mobile blood donation facilities while taking into account the inventory management in the blood center. Our case study is conducted on real-world instances of a Korean blood center. The results show that optimized schedules obtained from our model can significantly reduce total costs compared to two heuristic scheduling algorithms.
