In response to increasing supply chain costs, hospitals are investing in new technology to improve inventory visibility and control at the point of use. This poses new inventory optimization opportunities and challenges for hospital management. The technology-enabled increased inventory visibility allows hospitals to implement more sophisticated inventory policies to reduce costs and improve availability. One such policy, implemented at a large Midwest hospital, is a dual-source hybrid inventory system that combines periodic and continuous order-placement epochs under a single-item setting, in which different items are treated independently. In this paper, we extend the dual-source hybrid policy to a two-item setting. We propose different joint replenishment policies that take advantage of increased inventory visibility to coordinate periodic and continuous replenishments across items. We develop a simulation-based search engine and test the benefits of these different policies under different parameter settings. We find that more benefits can be obtained using simple joint replenishment policies than are obtained using just the hybrid policy without coordinated replenishments.

医院物资双重采购联合补货

为了应对不断增加的供应链成本,医院正在投资新技术以提高使用点的库存可见性和控制。这给医院管理带来了新的库存优化机会和挑战。技术支持的增加的库存可见性使医院能够实施更复杂的库存策略,以降低成本并提高可用性。在中西部的一家大型医院实施的一项此类政策是双源混合库存系统,该系统在单一项目设置下结合了定期和连续下单时期,其中不同项目被独立处理。在本文中,我们将双源混合策略扩展到两项设置。我们提出了不同的联合补货政策,这些政策利用增加的库存可见性来协调跨项目的定期和连续补货。我们开发了一个基于模拟的搜索引擎,并在不同的参数设置下测试了这些不同策略的好处。我们发现使用简单的联合补充策略可以获得比仅使用混合策略而不使用协调补充策略获得的收益更多。
