Abstract

The procurement of food grains from farmers is one of the biggest challenges under the COVID-19 outbreak due to country-wise lockdowns. The present study aims to reconfigure the existing food grain supply chain network. The study advances the extant literature by proposing a novel mathematical model that considers the government guidelines issued to procure food grains from farmers under the COVID-19 situation. The model includes personal distancing, a key parameter relevant in the COVID-19 crisis, and has remained unaddressed in the existing literature. The proposed model is tested in India. The effect of different parameters like personal distancing cost, carbon emission cost, fixed cost, and transportation cost is also investigated under a given set of procurement centers. Finally, the procurement schedule for each procurement center is generated, which is especially useful for managing its activities and is also helpful to farmers to streamline the process. Results indicate that the proposed model is highly effective under pandemic emergencies like the current COVID-19 crisis. Policymakers and the government will find this model helpful in drafting relevant policies regarding food grain procurement under emergencies such as the COVID-19 outbreak. The distribution segment of the supply chain network is not part of the present research work. In future studies, this part could be then added to the whole of the procurement process, and both procurement and distribution can be assessed together again.

摘要

由于各国实施封锁措施,在新冠疫情期间从农民手中采购粮食是最大的挑战之一。本研究旨在重新配置现有的粮食供应链网络。该研究通过提出一种新颖的数学模型推动了现有文献的发展,该模型考虑了在新冠疫情形势下政府发布的从农民手中采购粮食的指导方针。该模型纳入了人际距离这一在新冠危机中相关的关键参数,而现有文献中尚未涉及这一点。所提出的模型在印度进行了测试。在给定的一组采购中心下,还研究了人际距离成本、碳排放成本、固定成本和运输成本等不同参数的影响。最后,生成了每个采购中心的采购计划,这对于管理其活动特别有用,也有助于农民简化流程。结果表明,所提出的模型在当前新冠疫情这样的大流行紧急情况下非常有效。政策制定者和政府会发现该模型有助于起草关于在新冠疫情等紧急情况下粮食采购的相关政策。供应链网络的配送环节不属于本研究工作的范畴。在未来的研究中,可以将这一部分添加到整个采购过程中,并再次对采购和配送进行综合评估。
