Abstract
The COVID-19 outbreak has had a knock-on effect on the humanitarian supply chain. This research aims to identify the sourcing barriers in humanitarian charities’ supply chains and evaluate the interrelationships between the identified barriers. The agency theory and institutional theory are employed as the theoretical rationales to comprehend the value chain and operations of the humanitarian charity. To identify sourcing barriers related to humanitarian charities, a literature review and focus group discussion are conducted. Following the fuzzy Delphi method (FDM), 10 key barriers are chosen for further investigation. Finally, total interpretive structural Modeling (TISM) and matrix of cross-impact multiplications applied to a classification (MICMAC) are applied to further investigate the interrelationships among barriers and rank their priority. The findings are highly useful for the decision-makers to develop potential interventions based on the identified priorities.
