The occurrence of events that lead to interruptions in the flow of materials, even if these events happen in a distant place, can cause disruptions on a large scale. Disruptions are sudden and unexpected disturbances caused by various factors such as natural disasters, fires, loss of vital supplies, war, cyber-attacks, economic recession, sanctions and economic shocks, terrorism, epidemics, etc. Humanitarian supply chain is a special type of supply chain with unique features, which in these conditions plays a very important role in facing, controlling and reducing the effects of disasters. Therefore, the aim of this research is to present a humanitarian supply chain resilience model in dealing with epidemic diseases such the Coronavirus.

The research method is qualitative. Based on this, using the theory derived from the data, the humanitarian supply chain resilience model was formed in organizations providing humanitarian services. The result resulted in deriving the humanitarian supply chain model in dealing with epidemic diseases.

Based on the results of the research, it was determined that the mentioned model has 28 sub-categories in the form of 6 main categories is (causal conditions of resilience, attention to the resilience of the humanitarian supply chain, background conditions of resilience, intervening elements of resilience, strategies of resilience and consequences of resilience).

The COVID-19 pandemic has posed a significant challenge to the COVID-19 vaccine supply chain that need to be resolved for a successful exit from the pandemic. It is essential to identify and evaluate the risks associated with the vaccine supply chain. We propose a new measure for quantifying the resilience of the vaccine supply chain in Iran. To evaluate the resilience of the vaccine supply chain, we use a Bayesian network to consider the vulnerability and recoverability indices as well as the associated disruption propagation. This approach enables managers to measure the resilience of the supply chain and identify the reasons for performance decline due to the ripple effect. Our results show that outbreak risks, lack of access to vaccine suppliers, low efficacy of the vaccine against new variants, inaccurate prediction of vaccine demand, and failure to choose the right suppliers are the risks likely to have a high impact on the disruption of the vaccine supply chain. Our approach provides a useful tool for evaluating the resilience of the vaccine supply chain and identifying the critical risks. It can be used by decision-makers to mitigate the impact of disruptions and improve overall resilience of the vaccine supply chain.
