This paper deals with the optimization of the flow of sterile instruments in hospitals which takes place between the sterilization department and the operating theatre. This topic is especially of interest in view of the current attempts of hospitals to cut cost by outsourcing sterilization tasks. Oftentimes, outsourcing implies placing the sterilization unit at a larger distance, hence introducing a longer logistic loop, which may result in lower instrument availability, and higher cost. This paper discusses the optimization problems that have to be solved when redesigning processes so as to improve material availability and reduce cost. We consider changing the logistic management principles, use of visibility information, and optimizing the composition of the nets of sterile materials.
本文探讨了医院无菌器械在消毒科室与手术室之间流动的优化问题。鉴于当前医院通过外包消毒任务来削减成本的尝试，这一主题尤其引人关注。通常情况下，外包意味着将消毒单元设置在更远的地方，从而引入更长的物流循环，这可能导致器械可用性降低和成本增加。本文讨论了在重新设计流程时必须解决的优化问题，以提高物资可用性并降低成本。我们考虑改变物流管理原则、利用可视化信息以及优化无菌材料网络的构成。
