In the face of growing uncertainties, supply chain resilience is coming to be seen as increasingly important. Vulnerabilities revealed during the COVID-19 pandemic have highlighted the fragility of the global supply chain but have also spurred research and uncovered effective practices and strategies to mitigate and manage supply chain disruptions.
NCHRP Research Report 1154: Supply Chain Challenges and Solutions amid COVID-19, from TRB's National Cooperative Highway Research Program, provides an overview for understanding the elements of supply chains, describing the suppliers, manufacturers, distributors, retailers, and end users, as well as the supporting infrastructure. The supply chain challenges identified in this report are organized into eight categories: physical congestion and capacity, information and data, security, equipment, workforce, regulatory, and supplier source.
