摘要
为应对因突发事件造成大量人员伤亡而引起的用血量增长,血站往往过量增加库存以至造成血制品积压,因此必须及时转运积压血液制品以减小潜在的过期报废。通过分析库存状态,基于库龄推导出血液转运、接收的相关性质,建立最小化运输费用的转运模型;最后通过算例仿真验证了不同转运制品选择策略的差异以及保障概率、需求饱和度对使用新鲜度的调节作用,并分析了决策时刻对决策效果的影响,为应急保障中积压血液的转运决策问题提供了理论依据与实例参考。
To cope with the sharp rise in demand for blood in emergency, the blood bank tends to excessively increase the stock, which may cause the blood overstock. Therefore, it＇s necessary to transship the excessive stock to other blood banks to reduce the potential outdating. By analyzing the stock status, the age-based properties of transshipping and receiving are deduced, and a transshipment model is set up to minimize transport costs. The differences of decision effectiveness for two selection policies are studied in thia paper, which also reveals the influence of the support reliability coefficient, demand saturation coefficient and decision-making time on transshipment decision-making through simulation examples, so provide a tutorial for solving blood transshipment problem.
