公立医院药品联合库存模式下的供应中断风险管控研究

Joint Managed Inventory (JMI) is an effective strategy to resolve inefficiency of supply chain caused by current pharmaceutical supply systems of China’s public hospitals. Because of obvious reduction of average inventory level JMI may lead to supply interruption when encountering drug emergent and fluctuating demand, so it’s critical and necessary to improve supply interruption risk control ability of JMI. By analyzing the different impacts of Joint and Traditional inventory management strategies on the risks of the interruption, this project will explore how to effectively control the risks from the aspects of inventory strategy, emergency policy, node control and systematic operation. The highlights of the project are： 1) A dynamic decision-making model will be built to decide the safety stock levels and stock placement strategies；2）Emergency methods and policies will be proposed based on drug ownership features of JMI；3）A Vensim model will be established to simulate the implementation of joint inventory strategy to control the risks of supply interruption. The project is to improve the joint inventory management theory, lower the implementation risks and boost the decision makers’ confidence in China’s public hospitals.

联合库存有助于解决当前公立医院药品供应模式中效率低下问题。但实施联合库存后由于供应链平均库存水平降低，使新模式面对药品突发需求时可能会出现供应中断的情况，因此非常有必要加强供应中断的风险管控研究。课题研究的范围是药品联合库存模式相对于传统模式的差异性所导致的供应中断风险管控问题，具体为在公立医院药品供应领域实施联合库存后如何从库存策略、应急途径、节点协调机制设计、系统运作等角度有效进行供应中断风险管控。课题创造点为：1）提出了联合库存模式下安全库存水平计算以及存放策略的动态决策模型； 2）提出了基于联合库存物品所有权特点的药品应急途径和决策模式；3）建立基于系统动力学理论的药品联合库存仿真模型以控制供应中断风险。课题研究的目的是为了完善中国实施药品联合库存模式的理论基础，降低实施风险和提高决策者实施的信心。
