ABSTRACT: With the existence of COVID-19, the whole economy experienced
an unprecedented challenge. Organizations must be resilient to the ever-changing and unanticipated market to avoid being out of
the fierce competition. In an era of information explosion, managers require
a systematic, explicable, comparative, and traceable approach to evaluate and choose
suppliers. In recent years, procurement strategies
have been revamped due to the disruption in the global supply chain by the pandemic
and war in Europe. A wrong supplier selection decision seriously damages the
Company’s supply chain, operations, and reputation. Therefore, partnering with a
sustainable supplier is a prerequisite for business success. With the rising importance of sustainability, choosing a competent supplier is one of the significant strategic management decisions. A sustainable supplier impacts business operations and accelerates
long-term growth, enhancing efficiency and effectiveness. In the post-pandemic era,
it is expected to have new approaches to define inputs and outputs to rank suppliers
and logistics firms. This study uses Data Envelopment Analysis (DEA) to identify
a sustainable supplier. Our approach involves selecting suitable inputs and outputs,
improving the accuracy and relevance of the study to find sustainable/robust suppliers.
The results of this research have been implemented in the business intelligence
system of a company.
