Abstract

The catastrophes due to widespread outbreaks create a long-standing distraction and have an accelerating transmission. The uncontrolled outbreaks cause not only health-related problems but also supply chain related problems. The outbreak caused by the coronavirus (COVID-19) shows how vulnerable the Healthcare systems and the supporting systems such as supply chains of the countries to such type of disasters. Keeping high levels of inventory, especially for healthcare products, can be beneficial to overcome such shortage problems. Nevertheless, keeping a high level of inventory can be costly, and the durability of the products creates a limit. The decision-makers have to carefully decide the inventory levels by considering many factors such as the criticality of the product and the easiness of producing the product. In this study, we try to develop a decision model for defining the inventory levels in Healthcare systems by considering multiple scenarios such as outbreaks. A novel spherical regret based multi-criteria decision-making approach is developed and used for evaluating the total regret of not keeping stock of the healthcare equipment.

基于多准则球面模糊后悔的医疗器材库存评估

摘要

由于大范围爆发而造成的灾难造成了长期的干扰，并加速了传播。不受控制的暴发不仅造成与健康有关的问题，而且还导致与供应链有关的问题。由冠状病毒（COVID-19）引起的暴发表明，医疗保健系统和支持系统（如国家的供应链）对此类灾难的脆弱性。保持高水平的库存，特别是对于保健产品，可以克服此类短缺问题。然而，保持高水平的库存可能是昂贵的，并且产品的耐用性造成了限制。决策者必须通过考虑许多因素（例如产品的关键性和生产产品的难易程度）来仔细决定库存水平。在这个研究中，我们尝试通过考虑多种情​​况（例如暴发）来开发用于定义医疗保健系统中库存水平的决策模型。一种新颖的基于球形后悔的多标准决策方法被开发出来，并用于评估没有保持医疗设备库存的总遗憾。
