AI 中文摘要
医疗领域的循环供应链本质上十分复杂,其特征在于各参与主体间存在相互依赖关系,且产品流与性能存在高度不确定性。当前用于预测向循环经济(CE)转型效果的方法存在局限性,且大多为静态方法。本文展示了如何利用仿真技术评估引入循环产品的效果,以及在考虑变异性的情况下对整个医疗供应链的影响,选取腹腔镜剪刀供应链作为案例研究示例。据我们所知,这是首个从单个供应链成员及整个系统层面评估引入循环产品(医疗器械)设计影响的研究。该模型还可用于为医院提供最优库存策略相关信息,以确保患者安全和医院运营得到维持。我们的研究结果表明,采用循环产品可减少环境影响,但要实现成本和排放的显著降低,需要大量的前期投资。我们探讨了本研究在开发支持向循环经济转型的工具方面的理论与实践意义。
英文摘要
Circular healthcare supply chains are inherently complex, characterised by interdependencies among their actors and high uncertainty in product flows and performance. Current methods used to predict the outcomes of transitioning to circular economy (CE) are limited and mostly static. This paper demonstrates the use of simulation to assess the effect of introducing circular products and the implications across the healthcare supply chain accounting for variability. The laparoscopic scissors supply chain is chosen as a case study example. To the best of our knowledge, this is the first study that assesses the implications of introducing circular product (medical devices) designs at both the individual supply chain member and overall system level. The model can be also used to inform optimal inventory strategies for hospitals, to ensure that patient safety and hospital operations are maintained. Our findings suggest that adopting circular products can reduce the environmental impact, but to achieve significant reductions in both cost and emissions, it requires significant upfront investment. We discuss the theoretical and practical implications of our study in developing tools to support the transition to CE.
