Outline
This study investigates resilient supply chain-transport supernetworks, which can facilitate more resilient freight transport and supply chain networks to be established. Degree of network resilience was defined on the basis of robustness against and recovery from disasters. Dynamic supernetwork models were then developed, taking into account the degree of network resilience. An optimal network design model was also developed with such models being incorporated, as well as with heuristic solution procedures deriving high-quality solutions within reasonable computational time being proposed. It was indicated, through the numerical experiments utilizing the models developed, how to optimally recover a transport network from disasters in terms of the supernetwork resilience.
