Assessing Supply Chain Resilience with Supplier Influence via Network Reliability

Due to the recent impacts of pandemics, conflicts, and geopolitical factors, many supply chains are facing significant disruption risks. In this paper, the objective seeks to delve into the essential concepts of supplier influence and network reliability, especially within the context of a supply chain where each node represents a supplier, assembly plant, or market, and the arcs connecting the nodes represent transport carriers. The capacity of these carriers, symbolized by the available shipping containers, is not deterministic, as some capacity may be reserved for other markets. In this context, this supply chain network is referred to as a multistate supply chain network (MSC). Network reliability is defined as the probability that the MSC can successfully deliver goods to a market. By examining the changes in the network reliability through the addition of suppliers, decision-makers can leverage this analysis to adjust supplier configurations, maintaining supply chain stability by addressing variations in network reliability.
