Abstract: Recent occurrences of pandemics, geopolitical tensions, and regional conflicts have considerably heightened the risk of disruptions within global supply chains. In response to the growing need for resilience assessment, a quantitative metric is formulated to measure the susceptibility of supply chains to disruptions. A supply chain network is considered, where nodes represent suppliers, assemblers, or buyers, and edges denote transportation carriers from logistics companies. As suppliers and logistics companies serve multiple clients, production and transportation capacities are not guaranteed to be fully available. Given this context, the supply chain is modeled as a multistate supply chain network (MSCN). The network reliability defined as the probability of successful delivery of goods to a buyer by the MSCN, is subsequently adopted as a basis for resilience assessment. A resilience index is formulated by evaluating changes in network reliability before and after the addition of new suppliers, thereby quantifying the impact of supplier integration under disruption scenarios. Through this metric, supply chain resilience is assessed in a quantitative manner.
