Unfortunately, an abrupt corona-virus disease (COVID-19) outbreak brought a drastic change in human lives. Almost every sector of human-beings and their related activities are severely infected and affected by this COVID-19 pandemic. As days are passing, the impact of the COVID-19 epidemic is going to be more severe. The fundamental needs for personal protective equipment (PPEs) are rising drastically all over the world. In India, many non-pharmaceutical companies or organizations such as automobile companies are engaged in producing the PPEs at a very marginal rate. Thus this paper proposes a modeling and optimization framework for sustainable production and waste management (SPWM) decision-making model for COVID-19 medical equipment under uncertainty. To quantify the uncertainties among parameter values, we have taken advantage of the intuitionistic fuzzy set theory. A robust ranking function is presented to obtain a crisp version of it. Furthermore, a novel interactive intuitionistic fuzzy programming approach is developed to solve the proposed SPWM model. An ample opportunity to generate the desired solution sets are also depicted. The performance analysis based on multiple criteria such as savings from baseline, co-efficient of variations, and desirability degrees is also introduced. Practical managerial implications are also discussed based on the significant findings after applying to the real case study data-set. Finally, conclusive remarks and the future research direction are also addressed on behalf of the current contributing study.
不幸的是,新型冠状病毒肺炎(COVID-19)疫情的突然爆发给人类生活带来了巨大变化。几乎人类的每个领域及其相关活动都受到了这场COVID-19大流行的严重影响。随着时间的推移,COVID-19疫情的影响将更加严重。全球对个人防护装备(PPE)的基本需求正在急剧上升。在印度,许多非制药公司或组织,如汽车公司,正在以非常低的产量生产个人防护装备。因此,本文针对不确定性下COVID-19医疗设备的可持续生产与废物管理(SPWM)决策模型提出了一个建模与优化框架。为了量化参数值之间的不确定性,我们利用了直觉模糊集理论。提出了一种鲁棒排序函数以获得其清晰版本。此外,还开发了一种新颖的交互式直觉模糊规划方法来求解所提出的SPWM模型。还描述了生成所需解集的充足机会。还引入了基于多种标准的性能分析,如与基线相比的节省、变异系数和期望度。在将实际案例研究数据集应用后的重要发现基础上,还讨论了实际管理意义。最后,代表当前的研究成果给出了结论性评论和未来研究方向。
