The Influence of the Corona-Virus on the Tunisian Supply Chain and Transshipment Problem (Published)
This article aims to provide results of the impact of the Corona-Virus pandemic on the functioning of Tunisian companies. Based on a sample of these companies, the results showed a strong disruption of the various links in the supply chain following the generalized confinement of the population and the closure of borders.Overall, this study contributes both to the study of the effect of Corona-Virus on Supply Chain management and to the implications of the literature in this field and has important practical implications.We therefore sought to find out which links in the supply chain were the most impacted by applying ARENA modeling.The findings suggest that the analysis of the results makes it possible to detect the manifest existence of specific operating models.The Lateral-Transshipment and Commodity Allocation problem in the context of the COVID-19 outbreak has many novel features. For this, we propose a new multi-objective optimization model for Lateral-Transshipment of emergent products in two steps. The objectives envisaged are the optimization of the quality of the transhipped product, the satisfaction of customer demand and the minimization of the overall cost including the shortage penalty.
