Evaluating resilience in supply chain under disruptions - a renewal approach

Disruptions in supply chains are common all around the world. Hence, the effect of disruption on the supply chain must be analysed to assist enterprises in responding to the interruptions. The disruptions expose vulnerable spots in supply chain networks, resulting in delayed recovery. Therefore, improving supply chain resilience becomes an important issue. In this research, a renewal approach will be used to investigate resilience measures. The proposed approach helps determine the system's sustainability, vulnerability, and recoverability for a supplier who may encounter unforeseen events. Those resilience measures will be determined through the long-run proportions of time the system is in various states. Sensitivity analyses are also conducted to examine the influence of each system parameter on the resilience measures.
