Assessing the efficiency and vulnerability of global liner shipping network

Global liner shipping network (GLSN) constitutes an essential part of global maritime supply chains, but it could be vulnerable to disruptions. This paper develops integrated framework for assessing the efficiency and vulnerability GLSN. Specifically, a novel metric is proposed quantify performance GLSN, enables modeling different levels port disruption scenarios. Results show that overall GLSN quite robust under partial scenario any single (or country's ports), damage countries highly heterogeneous. Under dismantling scenarios where identified most critical ports (countries) are successively disrupted, increases non-linearly with increasing level disruption. Our findings demonstrate necessary monitor protect (countries); especially, avoiding their simultaneously complete disruptions vital importance functionality
