Impact of COVID-19 on Sustainability Enablers and Evaluation of Performance Index.

ABSTRACT

Sustainability deals with the impact of various processes and products on the economy, environment, and society. Due to the outburst of deadly coronavirus disease (COVID-19), sustainability which has three dimensions i.e., economy, environment, and social have been severely afflicted. Logistics has been stopped due to the spread of COVID-19 by which disruption in supply and demand takes place. This paper involves the study of the impact of COVID-19 on sustainability enablers. Also, the sub-attributes of sustainability enablers are studied and the performance index is calculated for pre and during COVID-19 with the help of the Graph-theoretic approach (GTA). With the help of the graph-theoretic approach (GTA), the inter-relationship between the sustainability enablers pre and during COVID-19 has been studied thereby quantitatively measuring the extent to which COVID-19 has an impact on sustainability enablers. The objective of this study is to identify a performance index by analyzing different sub-attributes of sustainability enablers. Also, digraphs are shown for the whole system and sub-systems representing inter-relationships and dependencies between various enablers and attributes to interpret the performance of the sustainability enablers before and during the time of COVID-19. This paper provides the impacts of COVID-19 on these three factors and provides the framework how to identify the performance index pre and during COVID-19.
