ABSTRACT
The Covid-19 pandemic [1] has severely disrupted companies' activities, especially in their supply chains. Indeed, the crisis has generated a disruption of supplies and therefore of supply and demand in different countries [2], a transformation of customer and supplier paradigms [3], and a revitalization of transport and logistics modes ([4];[1]). If the crisis continues to disrupt both the design and the management of companies' supply chains [5], the measurement of their performance, which is already largely controversial, must be revisited. This study aims at proposing the measurement of the performance of SCs with respect to the challenges and opportunities induced by the current COVID-19 pandemic. Its objective is to propose a prospective model for evaluating this performance in the post-pandemic period. The study analyzes the existing literature and proposes a set of indicators to measure the performance of SCs through a prospective approach. The indicators selected are relatively global and integrate financial and non-financial, strategic, tactical and operational dimensions. © 2022 IEEE.
