Modeling the Resilience of Supply Chains Subject to Disruptions to Logistics Hubs by Fabrizio Nocera, Alessandro Contento, and Paolo Gardoni
The well-being and economic prosperity of societies rely on large-scale interdependent infrastructure and their provision of goods and services. Natural hazards may damage components of the supply chain such as transportation infrastructure, and transport logistics hubs like ports and freight stations. Transport logistics hubs act as major multimodal hubs responsible for connecting different modes of transportation and where the transshipment of goods occurs. As an example, ports are complex systems, with both physical and institutional components that differ by function, cargo type, and geographic location. Due to their location along the coastline, ports are usually exposed to extreme weather events such as intense storms, flooding, and, in particular, hurricanes and related storm surge events. Past events have shown that the economic consequences of the disaster-related damage and failure of infrastructure are typically larger than the direct economic impact, i.e., the cost of repair of such infrastructure. Also, the extent of the impact often exceeds the immediate aftermath of a natural hazard and can be longstanding. While extensive research has been devoted to assessing the performance of infrastructure when facing a natural hazard, limited studies focused on the cascading effects of the failure of infrastructure on the performance of complex systems like businesses and supply chains. In this talk, we propose a mathematical formulation to model and quantify the impact of natural hazards on the supply chain by modeling the dependency of supply chain operations on physical infrastructure and their potential damage
