COVID-19's developing trend has put the waste management systems of governments all over the world in jeopardy. The increasing rise of infectious medical waste has now become a serious problem. This paper presents a multi-period multi-objective model for designing a medical waste management system during the COVID-19 pandemic. The model aims to reduce total costs of infectious medical waste management while also reducing the environmental impact of treatment centers, disposal centers, and transportation. It also aims to maximize the suitability of treatment technology based on social considerations and reduce the risk associated with processing and transporting COVID-19 waste. Different strategic and operational decisions are taken into account that include the selection of treatment technologies, the location of treatment and disposal centers, the flow of generated medical waste between facilities, and the number of vehicles required for the medical waste transport. The model tackles the uncertainty associated with model parameters, and it uses a credibility-based possibilistic programming method to deal with uncertainties. The suggested model is solved using an interactive fuzzy programming method and the importance of social indicators for selecting treatment technology is determined using the fuzzy best–worst approach. The effectiveness of the model is demonstrated by a practical case study in Shiraz, Iran. The numerical results can help system designers to achieve the most suitable trade-off between the sustainability goals and the safety viewpoint.

在 COVID-19 期间面临不确定性和风险的可持续医疗废物管理系统设计

COVID-19 的发展趋势使世界各国政府的废物管理系统处于危险之中。传染性医疗废物的日益增加现在已成为一个严重的问题。本文提出了一种多时期多目标模型,用于在 COVID-19 大流行期间设计医疗废物管理系统。该模型旨在降低传染性医疗废物管理的总成本,同时减少治疗中心、处置中心和运输对环境的影响。它还旨在基于社会考虑最大限度地提高处理技术的适用性,并降低与处理和运输 COVID-19 废物相关的风险。考虑到不同的战略和运营决策,包括处理技术的选择、处理和处置中心的位置、产生的医疗废物在设施之间的流动,以及医疗废物运输所需的车辆数量。该模型解决了与模型参数相关的不确定性,并使用基于可信度的可能性规划方法来处理不确定性。建议的模型使用交互式模糊规划方法求解,社会指标对选择治疗技术的重要性使用模糊最佳-最差方法确定。伊朗设拉子的一个实际案例研究证明了该模型的有效性。数值结果可以帮助系统设计人员在可持续性目标和安全观点之间实现最合适的权衡。该模型解决了与模型参数相关的不确定性,并使用基于可信度的可能性规划方法来处理不确定性。建议的模型使用交互式模糊规划方法求解,社会指标对选择治疗技术的重要性使用模糊最佳-最差方法确定。伊朗设拉子的一个实际案例研究证明了该模型的有效性。数值结果可以帮助系统设计人员在可持续性目标和安全观点之间实现最合适的权衡。该模型解决了与模型参数相关的不确定性,并使用基于可信度的可能性规划方法来处理不确定性。建议的模型使用交互式模糊规划方法求解,社会指标对选择治疗技术的重要性使用模糊最佳-最差方法确定。伊朗设拉子的一个实际案例研究证明了该模型的有效性。数值结果可以帮助系统设计人员在可持续性目标和安全观点之间实现最合适的权衡。建议的模型使用交互式模糊规划方法求解,社会指标对选择治疗技术的重要性使用模糊最佳-最差方法确定。伊朗设拉子的一个实际案例研究证明了该模型的有效性。数值结果可以帮助系统设计人员在可持续性目标和安全观点之间实现最合适的权衡。建议的模型使用交互式模糊规划方法求解,社会指标对选择治疗技术的重要性使用模糊最佳-最差方法确定。伊朗设拉子的一个实际案例研究证明了该模型的有效性。数值结果可以帮助系统设计人员在可持续性目标和安全观点之间实现最合适的权衡。
