Study on the Centralization Strategy of the Blood Allocation Among Different Departments within a Hospital

By far, the researches on how to distribute blood products among different departments in hospital have not been further studied, though the problem of blood shortage and wastage that caused by improper blood allocation is severe, which may endanger patient’s lives and impose considerable costs on hospitals. In order to solve this problem, this paper mainly studies on how to distribute the blood items among different departments within a hospital and investigates the allocation approach with the novel management method by centralizing the inventory of several different departments. By integrating the blood inventory requirements of some departments, the hospital could reduce the rate of blood shortage and wastage effectively, release the pressure of the occupancy of resources and reduce the bullwhip effect of blood products. This paper illustrates the centralization principle in hospital and formulates the mixed integer programming model to work out the optimal allocation network scheme and the optimal inventory setting for every department. And the results of the numerical example demonstrate that this centralization method could considerably reduce blood shortage and wastage in hospital by about 72% and 90% respectively. Furthermore, it could decrease the total cost by about 108,540 RMB a month on blood supply chain management in the hospital and improve the effect of some certain surgeries by transfusing the fresh blood to patients.     

SAR图像并行拼接方法研究与实现* 〖HT4K〗——基于改进完全二叉树模型

随着SAR成像技术的快速发展，SAR图像覆盖的地域范围与成像精度也在迅速增长，这对SAR图像拼接工作的实时性提出了挑战;文章对SAR图像序列特征进行深入分析，提出了采用基于分割的完全二叉树模型进行SAR图像的并行拼接，并使用MPI点对点通信方式对之进行了不同数量机群规模下的实现；对比实验证明，基于该方法的并行拼接工作比传统并行拼接方法在降低拼接时耗上更加有效，且并行拼接后的完整图像效果良好.
